    To compare variety and diversity patterns and dietary characteristics in Guatemalan women. Two non-consecutive 24-h recalls were conducted in convenience samples of 20 rural Mayan women and 20 urban students. Diversity scores were computed using three food-group systems.Variety and diversity scores and dietary origin and characteristics were compared between settings using independent t-test or Mann-Whitney-U-test. Dietary variety and diversity were generally greater in the urban sample when compared to the rural sample, depending on the number of days and food-group system used for evaluation.The diet was predominantly plant-based and composed of non-fortified food items in both areas.The rural diet was predominantly composed of traditional,non-processed foods. The urban diet was mostly based on non-traditional and processed items. Considerations of intervention strategies for dietary improvement and health protection for the Guatemalan countryside should still rely on promotion and preservation of traditional food selection.

    The complex, interacting influences on eating behavior and energy expenditure prevent elucidation of the causal role of any single factor in the current obesity epidemic. However, greater variety in the food supply, particularly in the form of highly palatable, energy-dense foods, has likely made a contribution. This study was undertaken to test the hypothesis that greater dietary variety is associated with greater caloric intake within individual meals consumed by free-feeding, socially-housed female rhesus monkeys. Meal patterns were assessed during two, two-week dietary phases. One phase consisted of a choice between a standard chow diet and a highly palatable diet (HPD). The other phase consisted of access to the chow only. Food intake for each subject was recorded continuously using previously validated, automated feeders, and a meal was defined based on a minimum kilocalorie requirement and a minimum inter-meal interval. During the choice condition, animals electively consumed mixed meals that incorporated both diets as well as other meals that consisted exclusively of a single diet - chow-only or HPD-only. Animals consumed the most calories per meal when the meal was comprised of both the chow and HPD, which differed in caloric density, flavor, and texture. Interestingly, however, there was no significant difference in the amount of calories consumed as HPD-only meals in the choice condition compared to meals in the chow-only, no choice condition, suggesting consumption of a single food during a meal, regardless of palatability, provides a constant sensory experience that may lead to more rapid habituation and subsequent meal cessation. Additionally, during the dietary choice condition, animals consumed fewer calories in the form of chow-only meals. Thus, the present results suggest that limiting dietary variety, regardless of palatability, may be a useful strategy for weight loss in overweight and obese individuals by reducing caloric intake within

    Full Text Available Nepal is one of the top twenty countries where potato contributes substantially for the human diet. Enhancing adoption of improved potato varieties could impact on farmer’s income, household food and nutritional security. As such, using a multistage sampling procedure, a study was conducted to assess the determinants of improved potato varieties adoption in Nepal covering 180 samples in four districts, two in hills and two in Tarai region. The study revealed that; Kavre and Bardiya districts in the hills and Tarai, respectively, were dominated by improved potato varieties adoption. On the other hand, Dhankuta and Jhapa in the hills and Tarai, respectively, were dominated by local potato varieties adoption. The informal seed sources followed by agro-vet and market were the major sources for improved varietal adoption. Farmers’ accesses to training and formal seed sources were important factor determining improved potato varietal adoption. However, households with larger farm size were less likely to allocate more area for improved potato varieties as many of farmers were reluctant to take potato cultivation as agri-business and still follow subsistence farming. Potato R&D programs, therefore, need to strengthen formal seed system to enhance access to quality potato seeds and build producer’s capacity through regular training and exposer visits in order to improve adoption of improved potato varieties in Nepal.

    Full Text Available Emergency food pantries provide food at no cost to low-resource populations. The purpose of this study was to evaluate single-day dietary intake patterns before and after visiting a food pantry among food-secure and food-insecure pantry clients. This observational cohort study comprised a paired, before-and-after design with a pantry visit as the intervention. Participants (n = 455 completed a demographic and food security assessment, and two 24-h dietary recalls. Adult food security was measured using the U.S. Household Food Security Survey Module. Dietary intake patterns were assessed using Automated Self-Administered 24-h Recall data and classified by Healthy Eating Index (HEI-2010 scores, dietary variety, number of eating occasions, and energy intake. Paired t-tests and Wilcoxon signed-rank tests compared outcomes before and after a pantry visit. Mean dietary variety increased after the pantry visit among both food-secure (p = 0.02 and food-insecure (p < 0.0001 pantry clients. Mean energy intake (p = 0.0003, number of eating occasions (p = 0.004, and HEI-2010 component scores for total fruit (p < 0.001 and whole fruit (p < 0.0003 increased among food-insecure pantry clients only. A pantry visit may improve dietary intake patterns, especially among food-insecure pantry clients.

    Rice (Oryza sativa L.) is an important cereal crops for human nutrition, this species can be divided into sub-species i.e. Indica and Japonica. Japonica sub-species consists of Temprate and Tropical Japonica (it is called as Javanica) groups. Mostly Javanica group originated from Indonesia, the people mentioned as Indonesian local varieties, it was covering more than 8000 varieties. This paper aims is to discuss the potential of mutation breeding, success stories and on going activities improved genetically the local rice varieties. Indonesian local varieties have been tested naturally for resistance to biotic and abiotic stresses so that they become useful collections of genetic resources. They usually adapted well toa specific environment where they grow largely, having good aroma and eating quality, but they have some weakness such very long growth duration, susceptible to lodging, unresponsive to fertilizer, and low yield. Seed multiplication is usually conducted by collecting seeds from farmer's fields so that the seed quality, especially for seeds purity level is very low. Improvements of seed quality is usually conducted through purification of exciting varieties, then, the result is released as a new variety. Other ways, some new varieties were improved through mutation breeding, for example, an early maturing mutant variety of Pandan Putri derived from irradiated Pandan Wangi variety from Cianjur area. The success story to reduce harvest age of Pandan Wangi variety through mutation breeding, it was triggers other local governments to use nuclear technology in improving agronomic traits of their local rice varieties, without altered another good characters.

    This study examined the factors related to intellectual activity in community-dwelling elderly persons. Self-administered questionnaires mailed to all people aged ≥65 years in a dormitory suburb in Japan (n = 15,210). The response rate was 72.2%. Analytical subjects (n = 8,910) were those who lived independently and completely answered questions about independent and dependent variables and covariates. Independent variables included psychosocial conditions (i.e., social activities, hobbies, and a sense that life is worth living (ikigai)), oral health (i.e., dental health behaviors and oral function evaluated by chewing difficulties, swallowing difficulties, and oral dryness), and dietary variety measured using the dietary variety score (DVS). A dependent variable was intellectual activity measured using the Tokyo Metropolitan Institute of Gerontology Index of Competence. Covariates included age, gender, family structure, pensions, body mass index, alcohol, smoking, medical history, self-rated health, medications, cognitive function, depression, and falling. Logistic regression was used to estimate the odds ratio (OR) for poor intellectual activity. Poor intellectual activity was reported by 28.9% of the study population. After adjustment for covariates and independent variables, poor intellectual activity was significantly associated with nonparticipation in social activities (OR = 1.90, 95%CI = 1.61-2.24), having neither hobbies nor ikigai (3.13, 2.55-3.84), having neither regular dental visits nor daily brushing (1.70, 1.35-2.14), the poorest oral function (1.61, 1.31-1.98), and the lowest DVS quartile (1.96, 1.70-2.26). These results indicate that psychosocial conditions, oral health, and dietary variety are independently associated with intellectual activity in elderly persons. The factors identified in this study may be used in community health programs for maintaining the intellectual activity ability of the elderly.

    The effects of the ripeness stage of banana (Musa AAA) and plantain (Musa AAB) peels on neutral detergent fibre, acid detergent fibre, cellulose, hemicelluloses, lignin, pectin contents, and pectin chemical features were studied. Plantain peels contained a higher amount of lignin but had a lower hemicellulose content than banana peels. A sequential extraction of pectins showed that acid extraction was the most efficient to isolate banana peel pectins, whereas an ammonium oxalate extraction was more appropriate for plantain peels. In all the stages of maturation, the pectin content in banana peels was higher compared to plantain peels. Moreover, the galacturonic acid and methoxy group contents in banana peels were higher than in plantain peels. The average molecular weights of the extracted pectins were in the range of 132.6-573.8 kDa and were not dependant on peel variety, while the stage of maturation did not affect the dietary fibre yields and the composition in pectic polysaccharides in a consistent manner. This study has showed that banana peels are a potential source of dietary fibres and pectins.

    Full Text Available Advancement in agricultural technologies is seen to result in the shift in production functions. The study was conducted to establish the impact of the improved rice variety on productivity in the Ejura-Sekyedumase and Atebubu-Amantin Municipalities of Ghana. The study was based on the survey of 208 rice farmers using a three-stage stratified sampling method. The study used a structured questionnaire to collect input-output data from the rice farmers. Data were analysed using the Cobb-Douglas production function. The study found that the technical change associated with the introduction of the improved rice variety was of the non-neutral type. Further, the adoption of the improved rice variety has increased rice productivity by about 46% for the adopters. The main determinants of productivity for the adopters were seed, land, fertiliser, herbicide, and education. Productivity among the non-adopters was positively influenced by seed, land, herbicide, and fertiliser. The study concluded that the improved rice variety has superior yield advantage. The study recommends for the simultaneous promotion of improved rice varieties and their recommended inputs to increase rice productivity.

  2. A Review of Dietary Fiber in the Diabetic Diet

    2017-06-01

    Full Text Available Dietary fibers are a type of carbohydrates that are found in plant-based foods. They are not absorbed or digested by the body, but play an important role in maintaining good health. There are two types of dietary fiber - soluble and insoluble. Most foods contain both types, but are usually richer in one type than the other. Current evidence suggests that high-fiber diets, especially of the soluble variety, may offer some improvement in weight management, in carbohydrate metabolism, lower total and LDL cholesterol, and have other positive effects in patients diagnosed with diabetes (improvement of insulin sensitivity, modulation of the secretion of certain gut hormones, improvement of various metabolic and inflammatory markers associated with the metabolic syndrome, thus reducing the risk of cardio-metabolic diseases. The aim of our review is to reinforce the role of dietary fiber in the improvement of diabetes management

    2009-01-01

    One of the peaceful applications of atomic energy is in the field of agriculture. It finds application in crop improvement, crop nutrition, crop protection and food preservation. Genetic improvement of crop plants is a continuous endeavor. Success of a crop improvement programme depends on the availability of large genetic variability, which a plant breeder can combine to generate new varieties. In nature, occurrence of natural variability in the form of spontaneous mutations is extremely low (roughly 10 -6 ), which can be enhanced to several fold (approximately 10 -3 ) by using ionizing radiations or chemical mutagens. Radiation induced genetic variability in crop plants is a valuable resource from which plant breeder can select and combine different desired characteristics to produce better crop varieties. Crop improvement programmes at Bhabha Atomic Research Centre (BARC) envisage radiation based induced mutagenesis along with recombination breeding in country's important cereals (rice and wheat), oilseeds (groundnut, mustard, soybean and sunflower), grain legumes (blackgram, mungbean, pigeonpea and cowpea), banana and sugarcane. The desirable traits which have been bred through induced mutations include higher yield, grain quality, early maturity, disease and pest resistance, improved plant type and abiotic stress resistance

    Several dietary patterns, both macronutrient and food based, can lead to weight loss. A key strategy for weight management that can be applied across dietary patterns is to reduce energy density. Clinical trials show that reducing energy density is effective for weight loss and weight loss maintenance. A variety of practical strategies and tools can help facilitate successful weight management by reducing energy density, providing portion control, and improving diet quality. The flexibility of energy density gives patients options to tailor and personalize their dietary pattern to reduce energy intake for sustainable weight loss. Copyright © 2017 Elsevier Inc.

    The hemodialysis (HD) diet, which is a high-calorie and high-fat regimen, may inadvertently lead to an inadequate dietary intake, resulting in undernutrition among elderly HD patients. Therefore, an attempt was made to improve the dietary intake by implementing a modified diet regimen in eligible elderly HD patients. Elderly HD patients who had ingested nutritional index [GNRI], 83.5±8.3; normalized protein catabolic ratio [nPCR], 0.78±0.14). The modified diet regimen, which involved reducing food portion sizes and incorporating a liquid diet, led to a significant increase in their dietary intake from 48.1% at baseline to 97.1% of the meals provided 3 months after the start of the modified HD diet regimen. Their GNRI also significantly increased from 83.5±8.3 to 86.1±10.2, and their serum albumin levels significantly increased from 3.2±0.2 g/dL to 3.4±0.4 g/dL, suggesting improvements in their nutritional status. The attempted dietary approach for elderly HD patients was shown to potentially increase their dietary intake and improve their nutritional status without affecting the efficiency of HD being implemented.

    Since 1971, the rice breeding program in Indonesia has developed on intensive program to improve varieties for yield potential, resistancy to major pests and diseases, early maturity good grain and eating quality. In recent years, the attacks of insects and diseases are very severe in rice cultivation in Asia. Much of the losses were due to acontinuous planting or certain varieties. Between 1966 and 1973 tungro occured in epidemic proportions on separate occasions in Indonesia, Thailand, Nort East India, Bangladesh, and Philippine. Since 1973, investation of brown planthopper and green leafhopper several damaged rice crop in most parts of Indonesia. Presently, rice improvement are directed to develop high yielding rice varieties that are resistant to brown planthopper, ragged stunt virus, blast, green leafhopper, and gallmidge. Screening for pests and diseases are conducted in the laboratory as well as in the field. The adoption of those improved varieties by farmers has contributed greatly in our efforts to attain self sufficiency in rice production in Indonesia. GH 147 -M-40 krad-Pn-89 (irradiated Barito) showed resistant to brown planthopper biotype 1 and 2 and moderately resistant to biotype 3. Napa 40 krad-St-12 has resistant reaction to blast.

    Dietary self-monitoring is linked to improved weight loss success. Mobile technologies, such as smartphone applications (apps), might allow for improved dietary tracking adherence. The authors assessed the use of a popular smartphone app for dietary self-monitoring and weight loss by comparing it with traditional diet counseling and entry methods. Diet tracking and weight loss were compared across participants during an 8-week weight loss trial. Participants tracked intake using 1 of 3 methods: the mobile app "Lose It!", the memo feature on a smartphone, or a traditional paper-and-pencil method. App users (n = 19) recorded dietary data more consistently compared with the paper-and-pencil group (n = 15; P = .042) but not the memo group (n = 13). All groups lost weight over the course of the study (P = .001), and no difference in weight loss was noted between groups. Smartphone apps could represent a novel and feasible dietary self-monitoring method for individuals. Copyright © 2014 Society for Nutrition Education and Behavior. Published by Elsevier Inc.

    Chemical compositions and glycemic indices of four varieties of banana (Musa spp.) (kolikuttu-Silk AAB, embul-Mysore AAB, anamalu-Gros Michel AAA, seeni kesel-Pisang Awak ABB) were determined. Silk, Gros Michel, Pisang Awak and Mysore contained the highest percentages of starch (14%), sucrose (38%), free glucose (29%) and fructose (58%) as a percentage of the total available carbohydrate content respectively. Total dietary fiber contents of four varieties ranged from 2.7 to 5.3%. Glycemic indices of Silk, Mysore, Gros Michel and Pisang Awak were 61 ± 5, 61 ± 6, 67 ± 7, 69 ± 9 and can be categorized as low against white bread as the standard. A single banana of the four varieties elicited a low glycemic load. Thus, consumption of a banana from any of these varieties can be recommended as a snack for healthy or diabetic patients who are under dietary management or pharmacological drugs to regulate blood glucose responses in between meals.

    Dietary acculturation, specifically the adoption of western dietary habits, may result in adverse health effects such as obesity and type 2 diabetes. Therefore, it is necessary to explore the role of acculturation in dietary patterns as well as awareness and knowledge of healthy nutrition among South Asian immigrants. This is an especially important population to target as South Asians have higher prevalence rates of type 2 diabetes and cardiovascular disease, which may be magnified with immigration. The current investigation is a sub-study of the Multi-Cultural Community Health Assessment Trial (M-CHAT). There were 207 participants of South Asian origin included in the initial study, 129 were born outside of Canada and had immigrated after the age of 18. The length of residence in Canada was used as a marker for acculturation. A questionnaire addressing perceived changes in dietary patterns, food preparation, and nutrition knowledge and awareness since immigration was used to assess dietary practices. The association between length of residence and variables related to perceived changes in dietary patterns was explored with Spearman correlation and significant associations were subsequently analyzed with ordinal logistic regression analysis adjusted for age, sex, education and body mass index. South Asian immigrants in Canada reported a variety of positive dietary practices, including an increased consumption of fruits and vegetables and an improvement in food preparation (including an increase in grilling and a decrease in deep frying when cooking). However, there was a reported increase in the consumption of convenience foods, sugar-sweetened beverages, red meat and in dining out. South Asian immigrants in Canada reported a variety of positive dietary practices including an improvement in food preparation. Future health promotion strategies should encourage cultural sensitivity in efforts to reduce the consumption of sugar-sweetened beverage, convenience foods

    The continuous improvement for rice through breeding is necessary to obtain new varieties with good quality and quantity. Cisantana variety hairy tips could be improved by mutation breeding. Seeds of Cisantana variety was irradiated by gamma rays ( 60 Co) at doses of 0.10, 0.20 and 0.30 kGy respectively at the Center for Application of Isotope and Radiation (CAIR) - Batan, Pasar Jumat, Jakarta. There after the irradiated seeds were planted as M1 plants at the CAIR’S experiment field in the dry season of 2000. Selection was carried out at the M2 generation and stressed on early maturity and bald spike. This was done at the experiment field at Pusakanegara - Subang in the Wet season of 2001/2002. From this population 19 mutants having early maturity and bald spike lets were selected. Purification in the next generation obtained 10 mutants which were homogeneous and without segregation. From these 10 mutants two mutant lines Obs-1688/PsJ and Obs-1692/PsJ were further tested. These two mutant lines showed good productivity and adaptability when tested at several locations. The resistance test for brown plant hopper and bacterial leaf blight disease showed that these two mutant lines are resistant to biotype 1 and 2, and medium resistant to biotype 3 of brown plant hopper, and also resistant to strain 3 and medium resistant to strain IV of bacterial leaf blight disease. These two mutant lines have good rice quality and were gelatinous. The Obs-1688/PsJ and Obs-1692/PsJ mutant lines were released as new rice varieties by the Minister of Agriculture and officially address as Mira-1 at 2006 and Bestari at 2008, respectively. (author)

    Suboptimal diet is a leading cause of cardiometabolic disease and economic burdens. Evidence-based dietary policies within 5 domains-food prices, reformulation, marketing, labeling, and government food assistance programs-appear promising at improving cardiometabolic health. Yet, the extent of new dietary policy adoption in the US and key elements crucial to define in designing such policies are not well established. We created an inventory of recent US dietary policy cases aiming to improve cardiometabolic health and assessed the extent of their proposal and adoption at federal, state, local, and tribal levels; and categorized and characterized the key elements in their policy design. Recent federal dietary policies adopted to improve cardiometabolic health include reformulation (trans-fat elimination), marketing (mass-media campaigns to increase fruits and vegetables), labeling (Nutrition Facts Panel updates, menu calorie labeling), and food assistance programs (financial incentives for fruits and vegetables in the Supplemental Nutrition Assistance Program (SNAP) and Women, Infant and Children (WIC) program). Federal voluntary guidelines have been proposed for sodium reformulation and food marketing to children. Recent state proposals included sugar-sweetened beverage (SSB) taxes, marketing restrictions, and SNAP restrictions, but few were enacted. Local efforts varied significantly, with certain localities consistently leading in the proposal or adoption of relevant policies. Across all jurisdictions, most commonly selected dietary targets included fruits and vegetables, SSBs, trans-fat, added sugar, sodium, and calories; other healthy (e.g., nuts) or unhealthy (e.g., processed meats) factors were largely not addressed. Key policy elements to define in designing these policies included those common across domains (e.g., level of government, target population, dietary target, dietary definition, implementation mechanism), and domain-specific (e.g., media channels

    Methods for conducting dietary assessment in the United States date back to the early twentieth century. Methods of assessment encompassed dietary records, written and spoken dietary recalls, FFQ using pencil and paper and more recently computer and internet applications. Emerging innovations involve camera and mobile telephone technology to capture food and meal images. This paper describes six projects sponsored by the United States National Institutes of Health that use digital methods to improve food records and two mobile phone applications using crowdsourcing. The techniques under development show promise for improving accuracy of food records.

  2. Improved Bean Varieties Make a difference in Western Kenya: An Impact Analysis

    2002-01-01

    A survey was conducted in Kakamega and Vihiga District of Western Kenya during 2001 cropping seasons to analyze impacts of root rot resistance bean varieties introduced in Kakamega and Vihiga Districts by KARI and CIAT between 1989 and 1998. The objective of the study were to: assess adoption of the introduced root rot resistance bush and climbing bean varieties, determine technological and socio-economic factors that enhances or lessen adoption and attainment of the impacts, and examine types and magnitude of the impacts of adoption of the improved bean varieties at farm-level. To form a composite picture on spread and impact of the varieties, a systematic approach was developed to collect and put together data from several sources mainly literature reviews and household surveys. Data were collected through interviews of 233 randomly selected households, using a structured questionnaire. Descriptive statistics and Tobit model were used to analyse the data. The study showed that although several improved bean varieties were disseminated, most farmers did not adopt all the varieties; 35-80% of the farmers had mainly adopted three bush beans KK22, KK15 and KK8. A relatively small portion of farmers (8-19%) adopted climbers. Disease resistance (root rot) was only one of the criteria, but not the most important one, farmers used in selecting the varieties they adopted. Result of Tobit analysis showed that farmers perception of the trait of the bean varieties as well as farm-farmer characteristics were important determinants of decisions to adopt and intensity the adoption. The main impacts of the new beans were their contribution to equity by improving food self-sufficiency for about 97-99% of te farmers. Most farmers used their bean harvest mainly for subsistence, only a few farmers sold beans in any given season. The 63% of the households that sold beans to earn cash income to purchase other types of food as well as investing in capital assets, especially household

    Full Text Available The objective of this study was to evaluate the nutritional compounds (fat, sugars, crude protein, soluble fiber, ash and starch of four emmer wheat varieties grown under the conditions of organic farming system. The experiment was established on Scientific Research base Dolná Malanta, near Nitra in Slovakia during 2010 – 2011 and 2011 – 2012 growing seasons. Nutritional parameters, except crude protein content, were not influenced by the variety and weather conditions. Agnone variety had the highest content of fat, crude protein and starch but the lowest content of soluble dietary fiber. The lowest values of fat, crude protein had Molise sel Colli variety; Farvento variety had the lowest sugars and starch content. Emmer wheat as ancient wheat has a unique composition in secondary components, such as starch, which may play a role as functional food ingredients.

    We assessed the nutritional status of patients with congenital heart disease (CHD) to evaluate the role of dietary intake in impaired weight for patient length. Underweight patients with CHD underwent nutritional counseling to evaluate the role of this intervention in improvement of weight for length. We prospectively evaluated a clinical protocol for nutritional assessment and counseling in patients with CHD. Eligible patients were enrolled from a cardiology clinic during a 13-month period. Initial anthropometric measurements and measurements of dietary intake of underweight and normal-weight patients were compared. Initial and follow-up measurements of underweight patients who received nutritional counseling were compared. Nineteen underweight patients with CHD and 16 normal-weight patients with CHD, aged 1 month to 2 years, were studied. Exclusion criteria included noncardiac factors that could affect growth (eg, low birth weight, Down syndrome, gastrointestinal deficit, and any severe abnormality of the central nervous system). Seventeen of the 19 underweight patients underwent nutritional counseling in the presence of a parent every 2 months for 6 months. Caloric and protein intakes were maximized using high-calorie formulas. Baseline dietary intake was lower in underweight patients than in normal-weight patients (mean percentage of the recommended daily allowance of calories, 89% vs 108%). Follow-up evaluation in normal-weight patients showed no change in percentage of ideal body weight for length. Follow-up evaluation in underweight patients showed improvement in mean dietary intake (from 90% to 104% of the recommended daily allowance of calories) and in mean percentage of ideal body weight for length after intervention (from 83.1% to 88.3%). Nutritional evaluation of patients with CHD demonstrated that underweight children had inadequate diets. Underweight patients with CHD who received nutritional counseling showed increased dietary intake and improved

    The use of simple screening tools to measure nutritional adequacy in a public health context in developed countries are currently lacking. We explore the relationship between food variety and nutrient intake of London school children using a simple tool with potential use for screening for inadequate diets. A cross-sectional survey was carried out in 2010. The survey included 2579 children aged 7-10 years in 52 primary schools in East London in the United Kingdom. The analysis included 2392 children (93% of the original sample). Food variety was assessed as the total number of listed foods recorded over 24 h using the validated Child and Diet Assessment Tool (CADET) comprising 115 listed foods divided into 16 food categories. Dietary quality was determined by the proportion of children meeting recommended intakes of individual micronutrients, namely, calcium, iron, zinc, folate, vitamin A and vitamin C. The mean number of CADET-listed foods consumed daily by children was 17.1 (95% CI: 16.8, 17.5). Children who consumed fewer than 11 foods on the collection day had particularly low nutrient intakes. Children consuming three different vegetables and two different fruits on average consumed 19-20 listed foods. It was estimated between 4 and 20% of children did not meet the recommended levels for individual micronutrients during the period of data collection. A simple method using food counts to assess daily food variety may help public health nutritionists identify groups of children at risk of inadequate diets.

    Eleven female participants from a NCAA Division I volleyball team were evaluated for adequate energy and macronutrient intake during two off-seasons. Total energy and macronutrient intake were assessed by food records and results were compared against estimated needs using the Nelson equation. Dietary intervention was employed regarding the individual dietary needs of each athlete as well as a pre- and post-sports nutrition knowledge survey. Post dietary intervention, total energy, and macronutrient intake improved, as well as a significant improvement in sports nutrition knowledge (p < 0.001). Nutrition education is useful in improving dietary intake and nutrition knowledge of female athletes. PMID:22822449

    A wide range of dietary carbohydrates, including prebiotic food ingredients, fermentable fibers, and milk oligosaccharides, are able to produce significant changes in the intestinal microbiota. These shifts in the microbial community are often characterized by increased levels of bifidobacteria and lactobacilli. More recent studies have revealed that species of Faecalibacterium, Akkermansia, and other less well studied members may also be enriched. We review the implications of these recent studies on future design of prebiotics and synbiotics to promote gastrointestinal health. Investigations assessing the clinical outcomes associated with dietary modification of the gut microbiota have shown systemic as well as specific health benefits. Both prebiotic oligosaccharides comprised of a linear arrangement of simple sugars, as well as fiber-rich foods containing complex carbohydrates, have been used in these trials. However, individual variability and nonresponding study participants can make the outcome of dietary interventions less predictable. In contrast, synergistic synbiotics containing prebiotics that specifically stimulate a cognate probiotic provide additional options for personalized gut therapies. This review describes recent research on how prebiotics and fermentable fibers can influence the gut microbiota and result in improvements to human health.

    Full Text Available Research was conducted from February to May, 2017 for socioeconomic assessment on maize production and adoption of open pollinated improved maize varieties in Dang district of Nepal. Altogether, 100 samples were taken by simple random sampling from the major maize growing areas and relevant publications were reviewed. Focal Group Discussion and Key Informant Survey were also done. Descriptive statistics, unpaired t-test, probit regression and indexing were used for data analysis using statistical tools- SPSS, STATA and MS-Excel. Probit econometric model revealed that ethnicity (1% level, gender (5% level, area under open pollinated improved maize (1% level, seed source dummy (1 % level and number of visits by farmers to agrovet (5% level significantly determined the adoption of open pollinated improved maize varieties. In addition, unpaired t-test revealed that the productivity of open pollinated improved maize varieties was significantly higher (at 1% level than local; also, the multinational companies' hybrids showed significantly higher productivity (at 1% level when compared to open pollinated improved varieties. Furthermore, indexing identified- lack of availability of quality seeds and fertilizers (I= 0.86 as the major problem associated with the maize production. Giving aggressive subsidy on open pollinated improved seeds and dealership to registered agrovets for selling the subsidy seeds could enhance the adoption. Moreover, government organizations working in the areas of agricultural extension and research must focus on adoption of open pollinated improved maize varieties among the farmers, substituting the local and developing the high yielding hybrid varieties in Nepal to increase the maize productivity.

    Full Text Available Methylsulfonylmethane (MSM has become a popular dietary supplement used for a variety of purposes, including its most common use as an anti-inflammatory agent. It has been well-investigated in animal models, as well as in human clinical trials and experiments. A variety of health-specific outcome measures are improved with MSM supplementation, including inflammation, joint/muscle pain, oxidative stress, and antioxidant capacity. Initial evidence is available regarding the dose of MSM needed to provide benefit, although additional work is underway to determine the precise dose and time course of treatment needed to provide optimal benefits. As a Generally Recognized As Safe (GRAS approved substance, MSM is well-tolerated by most individuals at dosages of up to four grams daily, with few known and mild side effects. This review provides an overview of MSM, with details regarding its common uses and applications as a dietary supplement, as well as its safety for consumption.

    Full Text Available Cereals, including barley, have been recognised as functional foods that provide beneficial effect on the health of the consumer and decrease the risk of various diseases. The aim of investigation was to determine the grain composition of barley varieties and perspective breeding lines bred in Latvia and to evaluate its functional ingredients. The results of analysis showed that protein content among varieties ranged from 106.6-146.8 g·kg-1, total dietary fibre 187.4-208.2 g·kg-1, β-glucans 42.8 g-49.4 g·kg-1, and amount of α-tocopherol 6.03-8.93 mg·kg-1. The sum of essential amino acids in barley grain samples was from 32.90 g·kg-1 to 38.71 g·kg-1. All varieties of hulled and hulless barley grain were found to be sources of protein with high biological value. Comparison of barley varieties bred in Latvia suggests that variety ‘Kornelija’ outperforms others in protein, dietary fibre and micronutrient content.

  15. Dietary manipulations for improving productivity in ruminant livestock

    Beever, D.E.

    1989-01-01

    Against a background of the major aspects of forage utilization by the rumen ecosystem and host animal metabolism, the need to manipulate the nature of the diet in order to improve animal productivity is reviewed. A number of criteria by which possible dietary manipulants should be considered are provided. The role of feed additives to manipulate rumen fermentation characteristics with respect to volatile fatty acid production, suppression of methanogenesis, and stimulation of microbial protein synthesis is discussed, and the possible benefits of changing the rumen microflora (e.g. by defaunation) are considered. The potential of nitrogen, energy and specific amino acid supplements to enhance rumen fermentation and/or nutrient absorption is examined and the paper concludes with consideration of possible areas where dietary manipulation could be beneficial, but to date suitable technology has not been satisfactorily developed. In this context, the nutritional effect of tannins, including enhancement of pronutritional and diminution of antinutritional factors, the suppression of rumen proteolysis and the ruminal protection of starch are examined.

  16. Dietary supplements and team-sport performance.

    Science.gov (United States)

    Bishop, David

    2010-12-01

    A well designed diet is the foundation upon which optimal training and performance can be developed. However, as long as competitive sports have existed, athletes have attempted to improve their performance by ingesting a variety of substances. This practice has given rise to a multi-billion-dollar industry that aggressively markets its products as performance enhancing, often without objective, scientific evidence to support such claims. While a number of excellent reviews have evaluated the performance-enhancing effects of most dietary supplements, less attention has been paid to the performance-enhancing claims of dietary supplements in the context of team-sport performance. Dietary supplements that enhance some types of athletic performance may not necessarily enhance team-sport performance (and vice versa). Thus, the first aim of this review is to critically evaluate the ergogenic value of the most common dietary supplements used by team-sport athletes. The term dietary supplements will be used in this review and is defined as any product taken by the mouth, in addition to common foods, that has been proposed to have a performance-enhancing effect; this review will only discuss substances that are not currently banned by the World Anti-Doping Agency. Evidence is emerging to support the performance-enhancing claims of some, but not all, dietary supplements that have been proposed to improve team-sport-related performance. For example, there is good evidence that caffeine can improve single-sprint performance, while caffeine, creatine and sodium bicarbonate ingestion have all been demonstrated to improve multiple-sprint performance. The evidence is not so strong for the performance-enhancing benefits of β-alanine or colostrum. Current evidence does not support the ingestion of ribose, branched-chain amino acids or β-hydroxy-β-methylbutyrate, especially in well trained athletes.

    Full Text Available Abstract Background The fastest growing age group globally is older adults, and preventing the need for long-term nursing care in this group is important for social and financial reasons. A population approach to diet and physical activity through the use of social services can play an important role in prevention. This study examined the effectiveness of a social health program for community-dwelling older adults aimed at introducing and promoting physical activity in the home at each individual’s pace, helping participants maintain good dietary habits by keeping self-check sheets, and determining whether long-standing unhealthy or less-than-ideal physical and dietary habits can be changed. Method This cluster randomized trial conducted at 6 community centers in an urban community involved 92 community-dwelling older adults aged 65–90 years. The intervention group (3 community centers; n = 57 participated in the social health program “Sumida TAKE10!” which is an educational program incorporating the “TAKE10!® for Older Adults” program, once every 2 weeks for 3 months. The control group (3 community centers; n=35 was subsequently provided with the same program as a crossover intervention group. The main outcome measures were changes in food intake frequency, food frequency score (FFS, dietary variety score (DVS, and frequency of walking and exercise. The secondary outcome measures were changes in self-rated health, appetite, and the Tokyo Metropolitan Institute of Gerontology (TMIG Index of Competence score. Results Compared to baseline, post-intervention food intake frequency for 6 of 10 food groups (meat, fish/shellfish, eggs, potatoes, fruits, and seaweed, FFS, and DVS were significantly increased in the intervention group, and interaction effects of FFS and DVS were seen between the two groups. No significant differences were observed between baseline and post-intervention in the control group. Frequency of walking and

    Full Text Available Good nutrition is a prerequisite for a healthy and active life, especially for agriculture-dependent households. However, diets in most households in Tanzania lack diversity because the intake of meat, poultry, fish, and vegetables and fruits is low. This study estimates factors influencing dietary diversity of the household, children under five years, and women using primary survey data. It qualitatively assesses male dietary patterns and men's potential role in improving the nutritional status of the entire household. The findings show that the most consumed foods within the household are cereals, vegetables, oils and fats, spices, condiments and beverages. Children (d = 0.4; p<0.05 and women (d = 0.5; p<0.01 in female-headed households have low dietary diversity compared to those in male-headed households. Women and children access less diverse diets since 46% and 26%, achieved minimum dietary diversity respectively. Production of vegetables (coef. 0.34; p<0.05 play an important role in improving the dietary diversity of women. Gender (coef. 0.05; p<0.10 and education of the household head (coef. 0.02; p<0.01, food preparation and nutrition training (coef. 0.10; p<0.05 are important factors influencing dietary diversity of the members of a household. Results suggest that there is a need to support community-based programs to provide information on food and the importance of vegetables, their preparation, consumption and utilization to address food and nutrition challenges. Men can contribute towards improving household nutrition security by reducing consumption of food away from the home, especially during periods of food shortages. We recommend the use of complementary quantitative research to determine the patterns and dynamics of men's dietary diversity and compare it with that of other household members.

    The influence of dietary lecithin at doses of 0, 4, 20 or 80 g/kg fed to finisher gilts for six weeks prior to slaughter on growth performance, carcass quality and pork quality was investigated. M. longissimus lumborum (loin) was removed from 36 pig carcasses at 24h post-mortem for Warner-Bratzler shear force, compression, collagen content and colour analyses. Dietary lecithin increased dressing percentage (P=0.009). Pork chewiness and collagen content were decreased by dietary lecithin (Plecithin had no effect on shear force, cohesiveness or hardness (P>0.05, respectively). Dietary lecithin reduced loin muscle L* values and increased a* values (Plecithin improved dressing percentage and resulted in less chewy and less pale pork. © 2013.

    Peru has high rates of iron deficiency anemia. The prevalence is 35% in nonpregnant women of fertile age and 24.7% in adolescent girls in slums of periurban Lima. The major cause of anemia is low intake of dietary iron. A community-based, randomized behavioral and dietary intervention trial was conducted to improve dietary iron intake and iron bioavailability of adolescent girls living in periurban areas of Lima, Peru. Results show that there was a change in knowledge about anemia and improved dietary iron intake in the 71 girls who completed the study compared with the 66 girls in the control group. Although the 9-mo. intervention was not sufficient to improve hemoglobin levels significantly, there appeared to be a protective effect in maintaining the iron status of girls in comparison with the control group.

    Full Text Available The aim of the study was to evaluate the effectiveness of implementing multimodal nutrition education intervention (NEI to improve dietary intake among university students. The design of study used was cluster randomised controlled design at four public universities in East Coast of Malaysia. A total of 417 university students participated in the study. They were randomly selected and assigned into two arms, that is, intervention group (IG or control group (CG according to their cluster. The IG received 10-week multimodal intervention using three modes (conventional lecture, brochures, and text messages while CG did not receive any intervention. Dietary intake was assessed before and after intervention and outcomes reported as nutrient intakes as well as average daily servings of food intake. Analysis of covariance (ANCOVA and adjusted effect size were used to determine difference in dietary changes between groups and time. Results showed that, compared to CG, participants in IG significantly improved their dietary intake by increasing their energy intake, carbohydrate, calcium, vitamin C and thiamine, fruits and 100% fruit juice, fish, egg, milk, and dairy products while at the same time significantly decreased their processed food intake. In conclusion, multimodal NEI focusing on healthy eating promotion is an effective approach to improve dietary intakes among university students.

    Unlike anticonvulsant drugs and vagus nerve stimulation, there are no guidelines regarding adjustments to ketogenic diet regimens to improve seizure efficacy once the diet has been started. A retrospective chart review was performed of 200 consecutive patients treated with the ketogenic diet at Johns Hopkins Hospital from 2007-2013. Ten dietary and supplement changes were identified, along with anticonvulsant adjustments. A total of 391 distinct interventions occurred, of which 265 were made specifically to improve seizure control. Adjustments lead to >50% further seizure reduction in-18%, but only 3% became seizure-free. The benefits of interventions did not decrease over time. There was a trend towards medication adjustments being more successful than dietary modifications (24% vs. 15%, p = 0.08). No single dietary change stood out as the most effective, but calorie changes were largely unhelpful (10% with additional benefit). PMID:24859788

    Background: Dietary simulation modeling can predict dietary strategies that may improve nutritional or health outcomes. Objectives: The study aims were to undertake a systematic review of simulation studies that model dietary strategies aiming to improve nutritional intake, body weight, and related chronic disease, and to assess the methodologic and reporting quality of these models. Methods: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guided the search strategy with studies located through electronic searches [Cochrane Library, Ovid (MEDLINE and Embase), EBSCOhost (CINAHL), and Scopus]. Study findings were described and dietary modeling methodology and reporting quality were critiqued by using a set of quality criteria adapted for dietary modeling from general modeling guidelines. Results: Forty-five studies were included and categorized as modeling moderation, substitution, reformulation, or promotion dietary strategies. Moderation and reformulation strategies targeted individual nutrients or foods to theoretically improve one particular nutrient or health outcome, estimating small to modest improvements. Substituting unhealthy foods with healthier choices was estimated to be effective across a range of nutrients, including an estimated reduction in intake of saturated fatty acids, sodium, and added sugar. Promotion of fruits and vegetables predicted marginal changes in intake. Overall, the quality of the studies was moderate to high, with certain features of the quality criteria consistently reported. Conclusions: Based on the results of reviewed simulation dietary modeling studies, targeting a variety of foods rather than individual foods or nutrients theoretically appears most effective in estimating improvements in nutritional intake, particularly reducing intake of nutrients commonly consumed in excess. A combination of strategies could theoretically be used to deliver the best improvement in outcomes. Study quality was moderate to

    2014-07-01

    Full Text Available One key reason for the failure of Jatropha plantation is the use of non-improved planting materials. We present in this paper a Jatropha variety (JO S2 through selective breeding with much better seed productivity than wild accessions as proven by field trials in Singapore and India. In a single farm trial in Singapore for two years, a comparison was conducted with accessions from China, India, Indonesia and Africa. It was found that all traits studied like seed yield, seed kernel content, seed oil content, fatty acid composition, phosphorus content and PE content differed significantly among and within the wild accessions. Overall, JO S2 was the best performer with the highest seed yield, high oil content and low phosphorus content. On two sites in Tamil Nadu, Southern India, this Jatropha variety produced up to 2.95 ton/ha of dry seeds in the first year and up to 4.25 ton/ha of dry seeds in the second year, much better than the local variety control. We attribute its higher seed productivity to early flowering, better self-branching, more flower/fruiting bunches, more fruits per bunch and importantly, better uniformity among plants. This exemplifies that breeding has improved Jatropha seed productivity which will lead to better economics for Jatropha plantation.

    Breeding disease-resistant varieties is one of the most effective and economical means to combat soilborne diseases in pulse crops. Commonalities between pathogenic and mutualistic microbe colonization strategies, however, raises the concern that reduced susceptibility to pathogens may simultaneously reduce colonization by beneficial microbes. We investigate here the degree of overlap in the transcriptional response of the Phytophthora medicaginis susceptible chickpea variety 'Sonali' to the early colonization stages of either Phytophthora, rhizobial bacteria or arbuscular mycorrhizal fungi. From a total of 6476 genes differentially expressed in Sonali roots during colonization by any of the microbes tested, 10.2% were regulated in a similar manner regardless of whether it was the pathogenic oomycete or a mutualistic microbe colonizing the roots. Of these genes, 49.7% were oppositely regulated under the same conditions in the moderately Phytophthora resistant chickpea variety 'PBA HatTrick'. Chickpea varieties with improved resistance to Phytophthora also displayed lower colonization by rhizobial bacteria and mycorrhizal fungi leading to an increased reliance on N and P from soil. Together, our results suggest that marker-based breeding in crops such as chickpea should be further investigated such that plant disease resistance can be tailored to a specific pathogen without affecting mutualistic plant:microbe interactions. © 2016 John Wiley & Sons Ltd.

    The composition of habitual diets is associated with adverse or protective effects on aspects of health. Consequently, UK public health policy strongly advocates dietary change for the improvement of population health and emphasises the importance of individual empowerment to improve health. A new and evolving area in the promotion of dietary behavioural change is e-Learning, the use of interactive electronic media to facilitate teaching and learning on a range of issues, including diet and health. The aims of this systematic review are to determine the effectiveness and cost-effectiveness of adaptive e-Learning for improving dietary behaviours. The research will consist of a systematic review and a cost-effectiveness analysis. Studies will be considered for the review if they are randomised controlled trials, involving participants aged 13 or over, which evaluate the effectiveness or efficacy of interactive software programmes for improving dietary behaviour. Primary outcome measures will be those related to dietary behaviours, including estimated intakes of energy, nutrients and dietary fibre, or the estimated number of servings per day of foods or food groups. Secondary outcome measures will be objective clinical measures that are likely to respond to changes in dietary behaviours, such as anthropometry or blood biochemistry. Knowledge, self-efficacy, intention and emotion will be examined as mediators of dietary behaviour change in order to explore potential mechanisms of action. Databases will be searched using a comprehensive four-part search strategy, and the results exported to a bibliographic database. Two review authors will independently screen results to identify potentially eligible studies, and will independently extract data from included studies, with any discrepancies at each stage settled by a third author. Standardised forms and criteria will be used.A descriptive analysis of included studies will describe study design, participants, the

    Full Text Available Despite the high prevalence of adolescent food insecurity in Ethiopia, there is no study which documented its association with suboptimal dietary practices. The objective of this study is to determine the association between adolescent food insecurity and dietary practices. We used data on 2084 adolescents in the age group of 13-17 years involved in the first round survey of the five year longitudinal family study in Southwest Ethiopia. Adolescents were selected using residence stratified random sampling methods. Food insecurity was measured using scales validated in developing countries. Dietary practices were measured using dietary diversity score, food variety score and frequency of consuming animal source food. Multivariable regression models were used to compare dietary behaviors by food security status after controlling for socio-demographic and economic covariates. Food insecure adolescents had low dietary diversity score (P<0.001, low mean food variety score (P<0.001 and low frequency of consuming animal source foods (P<0.001. After adjusting for other variables in a multivariable logistic regression model, adolescent food insecurity (P<0.001 and rural residence (P<0.001 were negatively associated with the likelihood of having a diversified diet (P<0.001 and frequency of consuming animal source foods, while a high household income tertile was positively associated. Similarly, multivariable linear regression model showed that adolescent food insecurity was negatively associated with food variety score, while residence in semi-urban areas (P<0.001, in urban areas (P<0.001 and high household income tertile (P = 0.013 were positively associated. Girls were less likely to have diversified diet (P = 0.001 compared with boys. Our findings suggest that food insecurity has negative consequence on optimal dietary intake of adolescents. Food security interventions should look into ways of targeting adolescents to mitigate these dietary consequences

    The potential dangers associated with dietary supplements sold for weight loss and muscle building are well documented and increasingly garnering the attention of the media, public, and government leaders. Public health professionals have an opportunity to improve population health in the context of dietary supplement use by translating scientific evidence into action. In this commentary, we discuss the potential to motivate corporate social responsibility (CSR) among manufacturers and retailers of dietary supplements sold for weight loss and muscle building. We examine levers available to public health professionals for generating voluntary corporate self-regulation by reviewing examples from successful CSR initiatives in other domains of public health and offering recommendations highlighting effective advocacy strategies. We encourage public health professionals to use one or multiple advocacy strategies to improve consumer protections for dietary supplements sold for weight loss and muscle building.

    1. This study was conducted to investigate the efficiency of threonine (Thr) supplementation on reducing dietary crude protein (CP) content and the effects of Thr on lipid metabolism in Pekin ducks. The effects of dietary CP concentration (160, 190 and 220 g/kg) and Thr supplemental concentration (0, 0.7, 1.4, 2.1 and 2.8 g/kg) on growth performance, carcass, liver lipid and plasma profiles were determined in Pekin ducks from 1-21 d of age. 2. A total of 720-d-old male Pekin ducks were randomly allotted to 1 of 15 dietary treatments with 6 replicate cages of 8 birds per cage for each treatment according to average body weight. 3. Dietary Thr supplementation improved growth performance and breast muscle percentage at all CP diets, and ducks fed Thr-supplemented diets had higher plasma concentrations of some plasma amino acids. Thr supplementation reduced the concentrations of total lipid, triglyceride, cholesterol in liver, and plasma low density lipoprotein cholesterin concentration at 160 and 190 g/kg CP, whereas it increased triglyceride concentration at 160 g/kg CP. 4. Thr requirements based on quadratic broken-line model estimation were 6.6 and 7.0 g/kg for optimal average daily gain (ADG), and 6.7 and 7.3 g/kg for breast muscle percentage of Pekin ducks from 1-21 d of age at 190 and 220 g/kg CP, respectively. The dietary Thr requirements and estimated ADG (55.18 vs. 55.86 g/d/bird) and breast muscle percentage (2.79% vs. 2.75%) of Pekin ducks did not differ between 190 and 220 g/kg CP according to the t-test results. 5. Dietary CP level could be reduced to 190 g/kg in Pekin ducks from 1-21 d of age with Thr supplementation to balance dietary amino acids, and Thr supplementation prevented excess liver lipid deposition in this instance.

    2017-01-01

    The chemical structure of polyphenols consisting of aromatic rings, capable of quenching free radicals, makes them ideal candidates to protect against oxidation. Polyphenols are present in a variety of foods including grapes, berries, dark chocolate, coffee and tea to mention a few. A number of studies have shown that dietary polyphenols exert a protective effect against hypertension, dyslipidemias, inflammation, endothelial function and atherosclerosis, conditions associated with increased risk for cardiovascular disease. Studies indicate that by decreasing cholesterol absorption, polyphenols alter hepatic cholesterol homeostasis resulting in decreases in plasma lipids and reduction in atherogenic lipoproteins thus having a protective effect against atherosclerosis; polyphenols have also been shown to decrease the activity of enzymes involved in the renin-angiotensinaldosterone system and improve blood pressure. Further, they have been recognized to increase nitric oxide production and to improve endothelial function. In this review we will present some of the evidence derived from epidemiological studies, clinical interventions as well as animal and cell studies supporting the cardioprotective effects of dietary polyphenols.

    The Brazilian dietary guidelines are based in part on mainstream United States' recommendations, in spite of the criticisms and shortcomings of the American guidelines. In this paper, Brazilian food guidelines are summarized and discussed in comparison with the USA recommendations. American and Brazilian dietary recommendations are quite similar in many aspects, particularly those related to variety in the diet, the importance of physical activity and weight management. Different to American guidelines, those from Brazil advise people to choose fresh foods, to prefer healthier types of fat, to limit trans fat intake and to eat good sources of protein, but does not recommend the consumption of whole grains. Besides the challenges related to their implementation, indicators for the evaluation of the effectiveness of these guidelines should be established from the beginning, particularly those related to changes in dietary habits and the prevalence of obesity.

    In accordance with US dietary guidance, incorporating variety into the diet can align with energy balance, though greater food variety in some categories may make energy balance more challenging. Thus, experimental and epidemiologic evidence is summarized on the relationship between food variety, food and energy intake, and energy balance. Lab-based, experimental research consistently demonstrates that greater variety within foods or sensory characteristics of food increases food and energy intake within an eating occasion. Epidemiologic evidence is less consistent, potentially driven by differing methodologies, particularly in defining and measuring food variety. Moreover, the effect of variety on energy balance appears to be moderated by food energy density. Integrating insights from experimental and epidemiologic research are essential for strengthening food variety guidance including developing evidence-based definitions of food variety, understanding moderators of the relationship, and developing practical guidance interpretable to consumers.

  19. Higher agrobiodiversity is associated with improved dietary diversity, but not child anthropometric status, of Mayan Achí people of Guatemala.

    Child undernutrition remains one of the greatest challenges for public health nutrition in rural areas in developing countries. Interventions aiming to increase and conserve agrobiodiversity seem to be promising alternatives to improve child nutrition. However, the existing literature on these interventions is not conclusive about their effectiveness in combating child undernutrition. We tested the hypothesis that 'higher agrobiodiversity is associated with greater dietary diversity and better anthropometric status' in rural Guatemala.Design/Setting/SubjectsIn the summer of 2016, we conducted a cross-sectional study with a sample of 154 children (6-60 months). We conducted dietary recalls and structured interviews, measured children's weight and height, and visited food production systems (Milpas, home gardens, coffee plantations). Crop species richness, nutritional functional diversity, dietary diversity scores and anthropometric status were calculated. Higher food self-sufficiency, nutritional functional diversity and dietary diversity scores were positively correlated with higher crop and animal species richness. Contrarily, remoteness to the local market was negatively correlated with dietary diversity scores. However, higher dietary diversity scores were not correlated with better child anthropometric status. Better child anthropometric status was positively correlated with improved sanitary conditions and maternal education; and negatively correlated with large household size and frequent child morbidity. Agricultural diversification could diversify diets, increase nutrient availability and improve child anthropometry. However, these interventions need to be accompanied by sanitation improvements, family planning, nutritional education and women's empowerment to strengthen their positive effect on diet and nutrition.

    Full Text Available The use of improved high yielding crop varieties is an important avenue for reducing hunger and food insecurity in developing countries. Using cross-sectional data obtained from a survey conducted during 2013 crop season, we performed a probit model (plot-level analysis to determine the probability of adopting new improved rice varieties (NIRVs by smallholder farmers particularly from two main agro-ecological regions (hills and tropical plain terai regions of Central Nepal. The results revealed that education, extension services and seed access play significant roles in adoption decisions. Additionally, farm and field characteristic variables such as farm size, endowment of favorable land type (e.g. lowlands, and animal power (e.g. oxen are the key factors influencing the probability of adopting NIRVs. The results showed that technology specific variables (e.g. yield potential and acceptability are significant for explaining adoption behavior, implying that it is important to take farmers’ preferences to varietal characteristics into consideration in the design of a research and development program. Given the significant role played by extension and access related variables, increased emphasis on information dissemination, field demonstration, and farmers’ participatory research and training programs to popularize new rice varieties and enhance their adoption rate are required. This also suggests that policy intervention should be made on improving the educational status of farming households, and developing programs on varietal package of rice seed which offer farmers a variety of choices among the appropriate pools of germplasm. Such programs ultimately help farmers develop more profit-oriented behavior which are necessary to enhance adoption rate, production and food security in the long run.

    Simple measures reflecting dietary quality are preferred for assessment of dietary intakes in low-income communities, e.g. dietary diversity that reflects a healthy, varied, nutritious diet, associated with nutrient adequacy. A strong association between household income and food access suggests dietary diversity assessment as one of the indicators of household food security. The aim of this study was to assess the food security situation of black women in an informal settlement by exploring their food access capabilities through dietary diversity measures and the coping strategies they employ to cope with poverty and hunger. A randomly selected sample of black women living in an informal settlement completed a pretested socio-demographic questionnaire (socio-economic circumstances) and validated questionnaires (1-wk quantified food frequency questionnaire: diversity measures; 24-h recall: nutrient intake; Cornell Hunger Scale: coping strategies). Food variety scores and food group diversity scores were calculated from frequency analyses for all foods and food groups. Nutrient adequacy ratios for various nutrients and the mean adequacy ratio for their diet were calculated. Relationships between dietary diversity and nutritional adequacy were investigated with Pearson correlations. Food variety score cut points were tested for sensitivity and specificity against nutritional adequacy. Intakes were deficient for all nutrients except carbohydrates. Individual mean ± SD nutrient adequacy ratios ranging between 0.15 ± 0.18 and 0.95 ± 0.19 confirmed the poor dietary quality. Zero to 40 individual foods were consumed, but the mean ± SD food variety score was only 3.17 ± 1.21, indicating low food diversity, as did the low dietary diversity score (2.82 ± 0.99) using 0 to 6 food groups. Limited food access and food variety in poor households resulted in inadequate nutrient intakes (low nutrient adequacy ratios), confirmed by poor dietary diversity (food variety score

    Dietary assessment can be challenging for many reasons, including the wide variety of foods, eating patterns and nutrients to be considered. In team-based primary care practice, various disciplines may be involved in assessing diet. Electronic-based dietary assessment (e-DA) instruments available now through mobile apps or websites can potentially facilitate dietary assessment. Providers views of facilitators and barriers related to e-DA instruments and their recommendations for improvement can inform the further development of these tools. The objective of this study was to explore provider perspectives on e-DA tools in mobile apps and websites. The exploratory sequential mixed methods design included interdisciplinary focus groups followed by a web-based survey sent to Family Health Teams throughout Ontario, Canada. Descriptive and bivariate analyses were completed. Focus group transcripts contributed to web-survey content, while interpretive themes added depth and context. 11 focus groups with 50 providers revealed varying perspectives on the use of e-DA for: 1) improving patients' eating habits; 2) improving the quality of dietary assessment; and, 3) integrating e-DA into the care process. In the web-survey 191 respondents from nine disciplines in 73 FHTs completed the survey. Dietitians reported greater use of e-DA than other providers (63% vs.19%; p = .000) respectively. There was strong interest among disciplines in the use of e-DA tools for the management of obesity, diabetes and heart disease, especially for patient self-monitoring. Barriers identified were: patients' lack of comfort with using technology, misinterpretation of e-DA results by patients, time and education for providers to interpret results, and time for providers to offer counselling. e-DA tools in mobile apps and websites may improve dietary counselling over time. Addressing the identified facilitators and barriers can potentially promote the uptake of e-DA into clinical practice.

    UK public health policy strongly advocates dietary change for the improvement of population health and emphasises the importance of individual empowerment to improve health. A new and evolving area in the promotion of dietary behavioural change is 'e-learning', the use of interactive electronic media to facilitate teaching and learning on a range of issues including health. The high level of accessibility, combined with emerging advances in computer processing power, data transmission and data storage, makes interactive e-learning a potentially powerful and cost-effective medium for improving dietary behaviour. This review aims to assess the effectiveness and cost-effectiveness of adaptive e-learning interventions for dietary behaviour change, and also to explore potential psychological mechanisms of action and components of effective interventions. Electronic bibliographic databases (Cumulative Index to Nursing and Allied Health Literature, The Cochrane Library, Dissertation Abstracts, EMBASE, Education Resources Information Center, Global Health, Health Economic Evaluations Database, Health Management Information Consortium, MEDLINE, PsycINFO and Web of Science) were searched for the period January 1990 to November 2009. Reference lists of included studies and previous reviews were also screened; authors were contacted and trial registers were searched. Studies were included if they were randomised controlled trials, involving participants aged ≥ 13 years, which evaluated the effectiveness of interactive software programs for improving dietary behaviour. Primary outcomes were measures of dietary behaviours, including estimated intakes or changes in intake of energy, nutrients, dietary fibre, foods or food groups. Secondary outcome measures were clinical outcomes such as anthropometry or blood biochemistry. Psychological mediators of dietary behaviour change were also investigated. Two review authors independently screened results and extracted data from

    To evaluate the response of wheat varieties to seed priming and salinity, an experiment was conducted in completely randomized design (CRD) with three replications at Institute of Biotechnology and Genetic Engineering (IBGE), KPK Agricultural University, Peshawar, Pakistan. The performance of 6 wheat varieties (Tatara-96, Ghaznavi-98, Fakhri Sarhad, Bakhtawar-92, Pirsabaq-2004 and Auqab-2000) at two seed conditions (primed with 30 mM NaCl and un primed) under four salinity levels (0, 40, 80 and 120 mM) was studied. Statistical analysis of the data revealed that salinity, seed priming and varieties had significantly (P= 0.05) affected shoot fresh weight plant/sup -1/ shoot dry weight plant/sup -1/, shoot Na/sup +/ contents (mg g/sup -1/ dry weight), shoot K/sup +/ contents (mg g/sup -1/ dry weight) and shoot K/sup +/Na/sup +/ ratio. Maximum shoot fresh weight plant/sup -1/ (7.71 g), shoot dry weight plant/sup -1/ (1.68 g), shoot K/sup +/ contents (1.39 mg g/sup -1/ dry weight) and shoot K/sup +/ Na/sup +/ratio (1.45) were recorded from Bakhtawar-92 as compared with other varieties. Highest shoot Na/sup +/ contents (1.43 mg g/sup -1/ dry weight) were recorded from Auqab-2000 when compared with other varieties. All parameters were enhanced with seed priming except shoot Na/sup +/ contents, which reduced significantly (p= 0.05) with seed priming. (author)

    This study was performed to examine how childhood dietary patterns change over the short term and which changes in diet-related behaviors influence later changes in individual dietary patterns. Using food frequency questionnaire data obtained from children at 7 and 9 years of age from the Ewha Birth and Growth Cohort, we examined dietary patterns by principal component analysis. We calculated the individual changes in dietary pattern scores. Changes in dietary habits such as eating a variety of food over two years were defined as "increased", "stable", or "decreased". The dietary patterns, termed "healthy intake", "animal food intake", and "snack intake", were similar at 7 and 9 years of age. These patterns explained 32.3% and 39.1% of total variation at the ages of 7 and 9 years, respectively. The tracking coefficient of snack intake had the highest coefficient (γ = 0.53) and that of animal food intake had the lowest (γ = 0.21). Intra-individual stability in dietary habits ranged from 0.23 to 0.47, based on the sex-adjusted weighted kappa values. Of the various behavioral factors, eating breakfast every day was most common in the "stable" group (83.1%), whereas consuming milk or dairy products every day was the least common (49.0%). Moreover, changes in behavior that improved the consumption of milk or dairy products or encouraged the consumption of vegetables with every meal had favorable effects on changes in healthy dietary pattern scores over two years. However, those with worsened habits, such as less food variety and more than two portions of fried or stir-fried food every week, had unfavorable effects on changes in healthy dietary pattern scores. Our results suggest that diet-related behaviors can change, even over a short period, and these changes can affect changes in dietary pattern.

    To implement and evaluate the effectiveness of a pharmacy elective on dietary supplements that emphasized evidence-based care. A 3-credit elective that employed both traditional lectures and a variety of active-learning exercises was implemented. The course introduction provided a background in dietary supplement use and evidence-based medicine principles before addressing dietary supplements by primary indication. Student learning was assessed through quizzes, case assignments, discussion board participation, and completion of a longitudinal group project. Precourse and postcourse surveys were conducted to assess students' opinions, knowledge, and skills related to course objectives. The course was an effective way to increase students' knowledge of dietary supplements and skills and confidence in providing patient care in this area.

    Full Text Available Apricot, with high contents of vitamin A and dietary fiber, is one of most popular summer fruit with its attractive color, flavor and aroma. Losses caused by late spring frosts, poor adaptation to different climatic conditions, short serving time of fresh apricot to the market, Sharka and Monilia diseases effect on fruits are the main problems of apricot production. In addition, due mainly to rapid change in consumer preferences, the demand for new varieties with different color, size, flavor and aroma is increased. A significant part of the apricot breeding program is concentrated in the northern hemisphere with leading countries of USA (74 varieties and France (70 varieties. Meanwhile, only 11 varieties were registered in Turkey. Seven of these varieties (Alata Yıldızı, Çağataybey, Çağrıbey, Dr. Kaşka, Şahinbey, Dilbay and Eylül were bred with crossbreeding techniques and others with selection methods. Alkaya suits to both drying and fresh consumption. Eylül and Mihralibey are late ripening varieties, and others are early or mid-season ripening varieties. In this paper, apricot breeding studies in Turkey are discussed considering their contents and breeding methods, and results of those studies were summarized.

    Field studies were conducted to determine the potential for alterations in photosynthetic performance and grain yield of four wheat (Triticum aestivum) varieties of India- Vidisha, Purna, Swarna and Naveen Chandausi by ambient ultraviolet radiation (UV). The plants were grown in specially designed UV exclusion chambers, wrapped with filters that excluded UV-B (solar UV exclusion increased the leaf mass per area ratio, leaf weight ratio and chlorophylls per unit area of flag leaves in all the four varieties of wheat. Polyphasic chlorophyll a fluorescence transients from the flag leaves of UV excluded wheat plants gave a higher fluorescence yield. Exclusion of solar UV significantly enhanced photosynthetic performance as a consequence of increased efficiency of PS II, performance index (PIABS) and rate of photosynthesis in the flag leaves of wheat varieties along with a remarkable increase in carbonic anhydrase, Rubisco and nitrate reductase activities. This additional fixation of carbon and nitrogen by exclusion of UV was channelized towards the improvement in grain yield of wheat varieties as there was a decrease in the UV-B absorbing substances and an increase in soluble protein content in flag leaves of all the four varieties of wheat. The magnitude of response for UV exclusion for all the measured parameters was higher in two varieties of wheat Vidisha and Purna as compared to Swarna and Naveen Chandausi. Cumulative stress response index (CSRI) for each variety was developed from the cumulative sum of physiological and yield parameters such as leaf mass area ratio of flag leaf, total chlorophyll content, performance index at absorption basis, rate of photosynthesis and grain yield. All the varieties had a negative CSRI, demonstrating a negative impact of ambient UV radiation. Naveen Chandausi and Swarna are less sensitive to ambient UV radiation; Vidisha is more sensitive to both UV-A and UV-B and Purna is more sensitive to ambient UV-B radiation. Copyright

    Probiotic administration can be a nutritional strategy to improve the immune response and growth performance of fish. The current study aimed to evaluate the effects of a probiotic blend (Bacillus sp., Pediococcus sp., Enterococcus sp., Lactobacillus sp.) as a dietary supplement on growth performance, feed utilization, innate immune and oxidative stress responses and intestinal morphology in juvenile Nile tilapia (Oreochromis niloticus). The probiotic was incorporated into a basal diet at three concentrations: 0 g/kg (A0: control), 3 g/kg (A1: 1.0×106 colony forming unit (CFU)/g) and 6 g/kg (A2: 2.3×106 CFU/g diet). After 8 weeks of probiotic feeding, weight and specific growth rate where significantly higher in fish-fed A1 diet than in fish-fed A0. Alternative complement in plasma was significantly enhanced in fish-fed A2 when compared with A0. The hepatic antioxidant indicators were not affected by probiotic supplementation. Villi height and goblet cell counts increased significantly in the intestine of fish-fed A1 and A2 diets compared with A0. The dietary probiotic supplementation was maintained until 20 weeks of feeding. Then the selected immune parameters, digestive enzymes and apparent digestibility of diets were studied. No effect of probiotic feeding was observed after that longer period supplementation. The dietary supplementation of mixed species probiotic may constitute a valuable nutritional approach towards a sustainable tilapia aquaculture. The improvement of the immune responses and intestinal morphology play an important role in increasing growth performance, nutrient absorption and disease resistance in fish, important outcomes in such a competitive and developing aquaculture sector.

  14. May Diet and Dietary Supplements Improve the Wellness of Multiple Sclerosis Patients? A Molecular Approach

    2010-01-01

    Full Text Available Multiple sclerosis is a complex and multifactorial neurological disease, and nutrition is one of the environmental factors possibly involved in its pathogenesis. At present, the role of nutrition is unclear, and MS therapy is not associated to a particular diet. MS clinical trials based on specific diets or dietary supplements are very few and in some cases controversial. To understand how diet can influence the course of MS and improve the wellness of MS patients, it is necessary to identify the dietary molecules, their targets and the molecular mechanisms involved in the control of the disease. The aim of this paper is to provide a molecular basis for the nutritional intervention in MS by evaluating at molecular level the effect of dietary molecules on the inflammatory and autoimmune processes involved in the disease.

    2014-01-01

    This review discusses dietary strategies that may improve the metabolic profile and body weight regulation in obesity. Recent evidence demonstrated that long-term health effects seem to be more beneficial for low-glycemic index (GI) diets compared to high-protein diets. Still, these results need to be confirmed by other prospective cohort studies and long-term clinical trials, and the discrepancy between these study designs needs to be explored in more detail. Furthermore, the current literature is mixed with regard to the efficacy of increased meal frequency (or snacking) regimens in causing metabolic alterations, particularly in relation to body weight control. In conclusion, a growing body of evidence suggests that dietary strategies with the aim to reduce postprandial insulin response and increase fat oxidation, and that tend to restore metabolic flexibility, have a place in the prevention and treatment of obesity and associated metabolic disorders.

    2016-01-01

    Full Text Available Non-farm activities have been generally considered as important strategy for overcoming credit constraints faced by rural households as well as for reducing poverty through income effect. This paper employs binary probit and average treatment effect to estimate the impact of participation in non-farm activities on adoption of improved cassava and beans varieties in South-Kivu, DR Congo. Results showed on one hand that the participation rate in non-farm activities in South-Kivu was 38% and 52.1% respectively for crafts and small businesses. On the other hand, the rate of adoption of new cassava and beans varieties were 14 and 28% respectively. Factors affecting the adoption rate were gender, education, household size, the presence of non-farm activities, household assets in terms of livestock owned, market access and access to the information on new technologies. These results demonstrate the tendency of rural households to include the practice of non-farm activities among their strategies for survival and diversify their sources of income or supplement farm income. Results of this study indicate a positive relationship between engagement of rural households in non-farm activities and their propensity to adopt improved varieties. There is still a huge gap between potential adoption rate and actual rate of adoption for cassava and beans improved varieties in the study area. Therefore, actors involved in the development of the agricultural sector have to be aware of the importance of these factors even when they are working for the promotion of purely agricultural activities.

    OBJECTIVE: Dietary protein dilution (PD) has been associated with metabolic advantages such as improved glucose homeostasis and increased energy expenditure. This phenotype involves liver-induced release of FGF21 in response to amino acid insufficiency; however, it has remained unclear whether...... dietary dilution of specific amino acids (AAs) is also required. Circulating branched chain amino acids (BCAAs) are sensitive to protein intake, elevated in the serum of obese humans and mice and thought to promote insulin resistance. We tested whether replenishment of dietary BCAAs to an AA-diluted (AAD......) diet is sufficient to reverse the glucoregulatory benefits of dietary PD. METHODS: We conducted AA profiling of serum from healthy humans and lean and high fat-fed or New Zealand obese (NZO) mice following dietary PD. We fed wildtype and NZO mice one of three amino acid defined diets: control, total...

    Full Text Available Dietary polyphenols represent a wide variety of compounds that occur in fruits,vegetables, wine, tea, extra virgin olive oil, chocolate and other cocoa products. They aremostly derivatives and/or isomers of flavones, isoflavones, flavonols, catechins andphenolic acids, and possess diverse biological properties such as antioxidant, antiapoptosis,anti-aging, anticarcinogen, anti-inflammation, anti-atherosclerosis, cardiovascularprotection, improvement of the endothelial function, as well as inhibition of angiogenesisand cell proliferation activity. Most of these biological actions have been attributed to theirintrinsic reducing capabilities. They may also offer indirect protection by activatingendogenous defense systems and by modulating cellular signaling processes such asnuclear factor-kappa B (NF-кB activation, activator protein-1(AP-1 DNA binding,glutathione biosynthesis, phosphoinositide 3 (PI3-kinase/protein kinase B (Akt pathway,mitogen-activated protein kinase (MAPK proteins [extracellular signal-regulated proteinkinase (ERK, c-jun N-terminal kinase (JNK and P38 ] activation, and the translocationinto the nucleus of nuclear factor erythroid 2 related factor 2 (Nrf2. This paper covers themost recent literature on the subject, and describes the biological mechanisms of action andprotective effects of dietary polyphenols.

    With rapidly changing dietary environment, dietary guidelines for Koreans were revised and relevant action guides were developed. First, the Dietary Guidelines Advisory Committee was established with experts and government officials from the fields of nutrition, preventive medicine, health promotion, agriculture, education and environment. The Committee set dietary goals for Koreans aiming for a better nutrition state of all after a thorough review and analysis of recent information related to nutritional status and/or problems of Korean population, changes in food production/supply, disease pattern, health policy and agricultural policy. Then, the revised dietary guidelines were proposed to accomplish these goals in addition to 6 different sets of dietary action guides to accommodate specific nutrition and health problems of respective age groups. Subsequently, these guidelines and guides were subjected to the focus group review, consumer perception surveys, and a public hearing for general and professional comments. Lastly, the language was clarified in terms of public understanding and phraseology. The revised Dietary guidelines for Koreans are as follows: eat a variety of grains, vegetables, fruits, fish, meat, poultry and dairy products; choose salt-preserved foods less, and use less salt when you prepare foods; increase physical activity for a healthy weight, and balance what you eat with your activity; enjoy every meal, and do not skip breakfast; if you drink alcoholic beverages, do so in moderation; prepare foods properly, and order sensible amounts; enjoy our rice-based diet.

    Meal planning could be a potential tool to offset time scarcity and therefore encourage home meal preparation, which has been linked with an improved diet quality. However, to date, meal planning has received little attention in the scientific literature. The aim of our cross-sectional study was to investigate the association between meal planning and diet quality, including adherence to nutritional guidelines and food variety, as well as weight status. Meal planning, i.e. planning ahead the foods that will be eaten for the next few days, was assessed in 40,554 participants of the web-based observational NutriNet-Santé study. Dietary measurements included intakes of energy, nutrients, food groups, and adherence to the French nutritional guidelines (mPNNS-GS) estimated through repeated 24-h dietary records. A food variety score was also calculated using Food Frequency Questionnaire. Weight and height were self-reported. Association between meal planning and dietary intakes were assessed using ANCOVAs, while associations with quartiles of mPNNS-GS scores, quartiles of food variety score and weight status categories (overweight, obesity) were evaluated using logistic regression models. A total of 57% of the participants declared to plan meals at least occasionally. Meal planners were more likely to have a higher mPNNS-GS (OR quartile 4 vs. 1 = 1.13, 95% CI: [1.07-1.20]), higher overall food variety (OR quartile 4 vs. 1 = 1.25, 95% CI: [1.18-1.32]). In women, meal planning was associated with lower odds of being overweight (OR = 0.92 [0.87-0.98]) and obese (OR = 0.79 [0.73-0.86]). In men, the association was significant for obesity only (OR = 0.81 [0.69-0.94]). Meal planning was associated with a healthier diet and less obesity. Although no causality can be inferred from the reported associations, these data suggest that meal planning could potentially be relevant for obesity prevention.

    Background: The beneficial cardiovascular effects of vegetables may be underpinned by their high inorganic nitrate content. Objective: We sought to examine the effects of a 6-wk once-daily intake of dietary nitrate (nitrate-rich beetroot juice) compared with placebo intake (nitrate-depleted beetroot juice) on vascular and platelet function in untreated hypercholesterolemics. Design: A total of 69 subjects were recruited in this randomized, double-blind, placebo-controlled parallel study. The primary endpoint was the change in vascular function determined with the use of ultrasound flow-mediated dilatation (FMD). Results: Baseline characteristics were similar between the groups, with primary outcome data available for 67 patients. Dietary nitrate resulted in an absolute increase in the FMD response of 1.1% (an ∼24% improvement from baseline) with a worsening of 0.3% in the placebo group (P nitrate group, showing a trend (P = 0.06) to improvement in comparison with the placebo group. Dietary nitrate also caused a small but significant reduction (7.6%) in platelet-monocyte aggregates compared with an increase of 10.1% in the placebo group (P = 0.004), with statistically significant reductions in stimulated (ex vivo) P-selectin expression compared with the placebo group (P nitrate were detected. The composition of the salivary microbiome was altered after the nitrate treatment but not after the placebo treatment (P nitrate treatment; of those taxa present, 2 taxa were responsible for >1% of this change, with the proportions of Rothia mucilaginosa trending to increase and Neisseria flavescens (P nitrate treatment relative to after placebo treatment. Conclusions: Sustained dietary nitrate ingestion improves vascular function in hypercholesterolemic patients. These changes are associated with alterations in the oral microbiome and, in particular, nitrate-reducing genera. Our findings provide additional support for the assessment of the potential of dietary nitrate as a

    Individuals who adhere to dietary guidelines provided during weight loss interventions tend to be more successful with weight control. Any deviation from dietary guidelines can be referred to as a "lapse." There is a growing body of research showing that lapses are predictable using a variety of physiological, environmental, and psychological indicators. With recent technological advancements, it may be possible to assess these triggers and predict dietary lapses in real time. The current study sought to use machine learning techniques to predict lapses and evaluate the utility of combining both group- and individual-level data to enhance lapse prediction. The current study trained and tested a machine learning algorithm capable of predicting dietary lapses from a behavioral weight loss program among adults with overweight/obesity (n = 12). Participants were asked to follow a weight control diet for 6 weeks and complete ecological momentary assessment (EMA; repeated brief surveys delivered via smartphone) regarding dietary lapses and relevant triggers. WEKA decision trees were used to predict lapses with an accuracy of 0.72 for the group of participants. However, generalization of the group algorithm to each individual was poor, and as such, group- and individual-level data were combined to improve prediction. The findings suggest that 4 weeks of individual data collection is recommended to attain optimal model performance. The predictive algorithm could be utilized to provide in-the-moment interventions to prevent dietary lapses and therefore enhance weight losses. Furthermore, methods in the current study could be translated to other types of health behavior lapses.

    Full text: Variety 'Bragg' (Jackson x D49-2491) of soybean (Glycine max. (L.) Merrill) was found to be high yielding and widely adaptable throughout India. Its yield stability, however, is unsatisfactory, probably due to low germinability necessitating use of higher seed rate. With the main objective to rectify this defect, mutagenesis involving chemical as well as physical mutagens was used. Dry seeds were treated with EMS or MMS (0.2, 0.4 and 0.6%), or gamma rays (15, 20 and 25 kR) with and without additional exposure to UV (2 hrs at 260 nm) in 1982. In M{sub 2}, a mutation frequency ranging from 2.24 to 22.85% was observed. Screening of M{sub 2} and of subsequent generations yielded a broad spectrum of mutations. Some of the mutants are agronomically useful. Among them, mutant 'T{sub 2}14' resulting from 25 kR gamma rays + UV, was found to possess better germinability (+15%), earliness (5 days) and high yield during both rainy and post-rainy seasons in 1986 and 1987, when compared with the parent variety 'Bragg'. The mutant has smaller seed-size (TGW 125 g) than the parent (145 g). In soybean, large-seeded varieties were reported to have poorer seed germinability. Thus, the better germinability of the mutant might be related to its reduced seed size. Seeds of the mutant show a light brown colour of the hilum in contrast to the black hilum of 'Bragg'. In other characters the mutant is similar to 'Bragg'. The mutant should have potential for commercial cultivation in India. For confirmation of its agronomically superior performance, it is undergoing national evaluation in multilocational trials under 'All India Co-ordinated Research Project on Soybean (ICAR)'. The strain has been named 'NRC-2'. (author)

    Full Text Available Traditional markets function as trading place, socio-culture interaction, and recreation facility either in regional or urban scope. Distribution and variety of spatial condition influence traditional markets’ planning both physically and non-physically. Therefore, this research aimed to conduct a mapping of traditional markets’ spatial distribution and variety as potential factors to improve spatial-based management. Analysis methods including: (1 Mapping by employing Geographic Information System, (2 Category Based Analysis (CBA, and (3 Interactive Analysis were applied in Surakarta City as the research location. The result of this research signifies that spatial variety and distribution of traditional markets in Surakarta had similar pattern between one market to others; overlapping service function; specific commodity types in accordance with the market’s characteristics; diverse operating hours. Spatial variety and distribution could be potential factors to improve traditional market management as shopping service. This result was contrasted with Central Place Theory by Christaller and NÆss & Jensen’s research finding stating that distance became a key factor influencing accessibility to a number of activity facilities. Therefore, distance toward the service center is not considered as the main factor in traditional market management. The main factor in managing and controlling traditional markets’ development includes service function, commodity specification, and operating hour’s flexibility.

    This study surveyed dietary intake and adherence to the Korean national dietary guidelines in Korean adolescents. To elucidate basic data for use in nutrition education, which aims to improve adolescent compliance with the national dietary guidelines and to increase the intake of dietary fiber, we evaluated the sources of fiber in adolescent diets. This study included 182 male and 212 female students from 2 middle schools in the Jeonju province. From November 15~20, 2011, we surveyed the students for general characteristics, adherence to the Korean national dietary guidelines, and dietary intake. Dietary fiber intake was 16.57 ± 6.95 g/day for male students and 16.14 ± 7.11 g/day for female students. The food groups that contributed most to dietary fiber intake were (in descending order) cereals, vegetables, seasoning, and fruits. The fiber-containing food items consumed most were cabbage- kimchi, cooked rice, instant noodles, and cabbage. Based on adherence to the Korean national dietary guidelines, the vegetable-based intake of dietary fiber in groups 1 (score 15~45), 2 (score 46~52), and 3 (score 53~75) were 4.41 ± 2.595 g/day, 4.12 ± 2.692 g/day, and 5.49 ± 3.157 g/day, respectively (p<0.001). In addition, the total intake of dietary fiber varied significantly among the three groups (p<0.001) as follows: Group 1, 14.99 ± 6.374 g/day; Group 2, 15.32 ± 6.772 g/day; and Group 3, 18.79 ± 7.361 g/day. In this study, we discovered that adherence to the Korean national dietary guidelines correlates with improved intake of dietary fiber. Therefore, marketing and educational development is needed to promote adherence to the Korean national dietary guidelines. In addition, nutritional education is needed to improve dietary fiber consumption through the intake of vegetables and fruits other than kimchi.

    There is wide recognition of the importance of healthy eating in cardiovascular health promotion. The purpose of this study was to identify the main dietary patterns among a Spanish population, and to determine their relationship with plasma lipid profiles. A cross-sectional analysis was conducted of data from 1290 participants of the Aragon Workers Health Study cohort. Standardized protocols were used to collect clinical and biochemistry data. Diet was assessed through a food frequency questionnaire, quantifying habitual intake over the past 12 months. The main dietary patterns were identified by factor analysis. The association between adherence to dietary patterns and plasma lipid levels was assessed by linear and logistic regression. Two dietary patterns were identified: a Mediterranean dietary pattern, high in vegetables, fruits, fish, white meat, nuts, and olive oil, and a Western dietary pattern, high in red meat, fast food, dairy, and cereals. Compared with the participants in the lowest quintile of adherence to the Western dietary pattern, those in the highest quintile had 4.6 mg/dL lower high-density lipoprotein cholesterol levels (P dietary pattern had 3.3mg/dL higher high-density lipoprotein cholesterol levels (P dietary pattern is associated with improved lipid profile compared with a Western dietary pattern, which was associated with a lower odds of optimal high-density lipoprotein cholesterol levels in this population.

    Full Text Available This study was conducted to investigate the effects of dietary supplementation with chromium chloride, CrCl3.6H2O (2mg kg–1 basal diet on the performance and immune response of broiler chickens under heat stress condition (25-43°C. A total of 80 one-day-old broiler chicks (Ross-308 were assigned to two treatment groups according to a completely randomized design. Each treatment consisted of four equal replicates, each contained ten chicks. Chicks were fed on basal diets supplemented with different concentrations of chromium (0 and 2 mg kg–1 CrCl3 from 1 to 35 days of age. Chromium supplementation as feed additives resulted in a slightly lower rectal temperature, and significantly (P<0.05 lower respiration rate for the broiler chickens received diet supplemented with chromium compared to the control (0 mg kg–1 CrCl3. Dietary chromium supplementation increased final body weight (BW at the end of the production period (5 weeks. Average weight gain was significantly (P<0.05 higher in chickens fed on chromium supplemented diet. Feed intake was not influenced by dietary chromium supplementation, however, the efficiency of feed conversion was improved (P<0.05 in chromium supplemented chickens. Furthermore, dressing percentage was significantly (P<0.05 higher in Cr-treated chickens compared to control chickens. Chromium supplementation significantly (P<0.05 improved the immune response to Newcastle Disease Virus vaccine (NDV. The present results suggest that dietary chromium supplementation provides a good nutritional management approach to ameliorate heat stress induced depression in production performance and immune response of broiler chickens.

    Full Text Available The recent rise in obesity is widely attributed to changes in the dietary environment (e.g., increased availability of energy-dense foods and larger portion sizes. However, a critical feature of our "obesogenic environment" may have been overlooked - the dramatic increase in "dietary variability" (the tendency for specific mass-produced foods to be available in numerous varieties that differ in energy content. In this study we tested the hypothesis that dietary variability compromises the control of food intake in humans. Specifically, we examined the effects of dietary variability in pepperoni pizza on two key outcome variables; i compensation for calories in pepperoni pizza and ii expectations about the satiating properties of pepperoni pizza (expected satiation. We reasoned that dietary variability might generate uncertainty about the postingestive effects of a food. An internet-based questionnaire was completed by 199 adults. This revealed substantial variation in exposure to different varieties of pepperoni pizza. In a follow-up study (n= 66; 65% female, high pizza variability was associated with i poorer compensation for calories in pepperoni pizza and ii lower expected satiation for pepperoni pizza. Furthermore, the effect of uncertainty on caloric compensation was moderated by individual differences in decision making (loss aversion. For the first time, these findings highlight a process by which dietary variability may compromise food-intake control in humans. This is important because it exposes a new feature of Western diets (processed foods in particular that might contribute to overeating and obesity.

    Full Text Available ABSTRACT Sustained swimming (SS usually promotes beneficial effects in growth and feed conversion of fishes. Although feed efficiency is improves at moderate water velocity, more information is required to determine the contributions of this factor on growth and body composition. Body composition and efficiency responses to the use of nutrients were determined in juvenile matrinxa Brycon amazonicus (Spix and Agassiz, 1829 fed with two dietary amounts of protein, 28 or 38% of crude protein (CP, and subjected to sustained swimming at a constant speed of 1.5 body lengths s−1 (BL s−1 or let to free swimming. The fish body composition under SS and fed with 28% of dietary protein showed 22% of increased in bulk protein and a 26% of decrease in water content in the white muscle. Red muscle depicted 70% less water content and a 10% more lipid. Nutrient retention was enhanced in fish subjected to SS and a higher gain of ethereal extract sustained was observed in the white muscle of exercised fish fed with 38% CP. The interaction between swimming and dietary protein resulted in a larger bulk of lipid in red muscle. Fish fed with 28% CP under SS at 1.5 BL s−1 presented the best utilization of dietary nutrients and body composition. Thus, this fish farming procedure is proposed as a promising management strategy for rearing matrinxa.

    Full Text Available Background Impaired sleep quality is commonplace within industrialized societies, as evidenced by the increasing number of prescription sleep aids available. Certain herbal preparations have been suggested to provide a natural benefit to sleep; however, limited controlled data are available documenting this benefit. In the present study we tested the effect of an experimental dietary supplement, containing the active ingredients Chlorophytum borivilianum and Velvet bean, on sleep quality using the Pittsburgh Sleep Quality Index (PSQI. Methods Eighteen healthy and active men and women, with evidence of impaired sleep quality, consumed the supplement daily for 28 days. The PSQI was administered before and after the intervention period. As indicators of safety, resting heart rate and blood pressure were measured, and a complete blood count, comprehensive metabolic panel, and lipid panel were determined. Results Sleep quality was influenced by the supplement, as evidenced by an improvement in every category of the PSQI questionnaire ( P < 0.05, with most category scores improving approximately 50% from pre to post intervention. No adverse outcomes were noted with use of the supplement, as indicated by no change in resting heart rate, blood pressure, or any bloodborne parameter. Conclusions An investigational dietary supplement containing the active ingredients Chlorophytum borivilianum and Velvet bean improves sleep quality in men and women. Additional placebo controlled trials are needed to corroborate these findings in individuals with self-reported sleeping difficulty.

    Full Text Available Poultry welfare has been extensively studied; however, there is a lack of rigorous scientific knowledge relating to the different aspects of welfare factors and how this may contribute to the production quantity and product quality as well as the welfare of chickens. Therefore, we conducted an integrated study to compare welfare factors in chickens by providing free dietary choice under cage rearing, and further comparing cage rearing with free-range rearing. One hundred chickens each were allocated to a cage rearing group with conventional feeding (CC, a cage rearing group with free dietary choice of mealworms (FDM, a cage rearing group with free dietary choice of mealworms and fresh grass (FDMG, and a free-range rearing system group with free dietary choice of mealworms and fresh grass (FRMG. Results showed that under cage rearing, free dietary choice contributed to better meat quality and gait score, higher values of blood platelets, and a richer gut microbial composition, but poorer egg production than CC chickens. As compared to FDMG, FRMG chickens showed better meat quality, gait score, and feather conditions, as well as a richer gut microbial composition; however, they had poorer egg production and a poorer foot pad and foot feather condition. We conclude that free dietary choice and free-range rearing systems improve the product quality, gait score, and microbial richness of chickens.

    To evaluate the effect of a dietary supplement containing polyunsaturated fatty acids, in association with Humulus lupulus extract, on the quality of sleep using the Leeds sleep evaluation questionnaire (LSEQ) in subjects with moderate to severe sleep disorders. Randomized placebo-controlled trial, in a Population-based setting. Participants were adult patients 25 to 65 years old with a chronic primary insomnia who volunteered for the study. The tested intervention consisted of two soft gelatine capsules per day, containing either the dietary supplement (active group) or olive oil (placebo group) for a month. Subjects could also volunteer for two ancillary studies on melatonin and actigraphy. Evaluation criteria included i) perception of the quality of sleep at the end of treatment using the LSEQ questionnaire, ii) sleep efficiency measured by one-week actigraphic movement measurement performed before and during the treatment in a subsample of subjects, iii) night melatonin and 6 sulfatoxymelatonin (aMT6S) urine rates in a subsample of subjects. The average of Leeds score was similar in both groups (p = 0.95). A marked improvement in the quality of sleep was observed in both placebo (62%) and active (65%) group (p = 0.52). The evolution of urinary melatonin, aMT6S, and of the Mel/aMT6S ratio showed no differences between the two groups. Sleep efficiency, as measured by actigraphy, improved similarly in both groups during the treatment period, from 72% to 76% and 75% in the active and placebo group respectively (p = 0.91). The dietary supplement had neither effect on the perceived quality of sleep, nor on the melatonin metabolism and sleep-wake cycle. clinical trials.gov:NCT00484497.

    Worksite dietary interventions show substantial potential for improving employee health and well-being. The aim of this pilot study was to determine the effect of a worksite nutrition intervention on improving well-being. Thirty-five university employees participated in a 6-week nutrition intervention. The dietary protocol emphasized the daily consumption of greens, beans/legumes, a variety of other vegetables, fruits, nuts, seeds, and whole grains, referred to as a micronutrient-dense, plant-rich diet. Participants were encouraged to minimize the consumption of refined foods and animal products. Significant improvements in sleep quality, quality of life, and depressive symptoms were found. Findings reveal that a worksite nutrition intervention is effective at improving sleep quality, quality of life, and depressive symptoms with a projected improvement in work productivity and attendance.

    This study aimed to determine the effects of supplementing the diet of adult Nile tilapia Oreochromis niloticus with phosphatidylcholine (PC) on growth performance, body composition, fatty acid composition and gene expression. Genetically Improved Farmed Tilapia fish with an initial body weight of 83·1 (sd 2·9) g were divided into six groups. Each group was hand-fed a semi-purified diet containing 1·7 (control diet), 4·0, 6·5, 11·5, 21·3 or 41·0 g PC/kg diet for 68 d. Supplemental PC improved the feed efficiency rate, which was highest in the 11·5 g PC/kg diet. Weight gain and specific growth rate were unaffected. Dietary PC increased PC content in the liver and decreased crude fat content in the liver, viscera and body. SFA and MUFA increased and PUFA decreased in muscle with increasing dietary PC. Cytoplasmic phospholipase A 2 and secreted phospholipase A 2 mRNA expression were up-regulated in the brain and heart in PC-supplemented fish. PC reduced fatty acid synthase mRNA expression in the liver and visceral tissue but increased expression in muscle. Hormone-sensitive lipase and lipoprotein lipase expression increased in the liver with increasing dietary PC. Growth hormone mRNA expression was reduced in the brain and insulin-like growth factor-1 mRNA expression in liver reduced with PC above 6·5 g/kg. Our results demonstrate that dietary supplementation with PC improves feed efficiency and reduces liver fat in adult Nile tilapia, without increasing weight gain, representing a novel dietary approach to reduce feed requirements and improve the health of Nile tilapia.

    To evaluate the effect of an exploratory 12-week nutrition, cooking, and gardening trial (LA Sprouts) on preference for fruit and vegetables (FV); willingness to try FV; identification of FV; self-efficacy to garden, eat, and cook FV; motivation to garden, eat, and cook FV; attitudes toward FV; nutrition and gardening knowledge; and home gardening habits. Randomized controlled trial. Four elementary schools. Three hundred four predominately Hispanic/Latino third- through fifth-grade students were randomized to either the LA Sprouts group (n = 167 students) or control group (n = 137 students). Twelve-week after-school nutrition, cooking, and gardening intervention. Determinants of dietary behavior as measured by questionnaire at baseline and postintervention. Analyses of covariance. After the 12-week program, compared with controls, LA Sprouts participants improved scores for identification of vegetables (+11% vs +5%; P = .001) and nutrition and gardening knowledge (+14.5% vs -5.0%; P = .003), and were more likely to garden at home (+7.5% vs -4.4%; P = .003). The LA Sprouts program positively affected a number of determinants of dietary behaviors that suggest possible mechanisms by which gardening and nutrition education act to improve dietary intake and health outcomes.

    Social Marketing Theory is a comprehensive approach of program development encompassing the needs and preferences of the intended audience. It was hypothesized a Social Marketing Theory-based, registered dietitian-led, in-home, cardiovascular disease-targeted diet-education program would improve the dietary status of community-residing older women. Using a randomized control group design, this 90-day program in two North Carolina counties included 58 women (30 control; 28 intervention) ages 54 to 83 years. Data were collected using the Mini Nutritional Assessment, three 3-day food records, and program evaluations. The intervention group received two individual registered dietitian-led in-home education sessions and the control group received education material mailings (Visits 2 and 3). Pretested education materials were used. Visits/mailings were scheduled 28 to 30 days apart. Variables measured included cardiovascular disease-related dietary practices and dietary status (Mini Nutritional Assessment). Data were analyzed using descriptive statistics, paired sample t tests, multivariant analyses, and independent t tests. Intervention and control Mini Nutritional Assessment scores improved (P=0.0001). Intervention subjects consumed more fiber than control (P=0.013) and reduced sodium intake (P=0.02). Controls reduced energy (P=0.01) and cholesterol intakes (P=0.029), likely because of the decreased food intake. The majority (n=51, 87.9%) rated the program as good to excellent and almost all (n=55, 94.8%) would recommend the program to a friend. The most popular features of the program were the individualized sessions (n=20, 34.5%) and diet analyses (n=11, 19%). These results suggest that cardiovascular disease diet-education materials utilizing Social Marketing Theory principles can lead to improved dietary status among community-residing older women.

    Consistent guidelines across the world for dietary standards of trace elements remain elusive. Harmonization of dietary standards has been suggested by international agencies to facilitate consistency in food and nutrition policies and international trade. Yet significant barriers exist to standardize recommendations on a global basis, such as vast differences in geography, food availability and transport; cultural, social and economic constraints, and biological diversity. Simple commonality is precluded further by the variety of terminologies among countries and regions related to diet. Certain unions have created numerous nutritional descriptive categories for standards, while other large countries are limited to only a few. This paper will explore the global multiplicity of dietary standards and efforts for harmonization. Copyright © 2012 Elsevier GmbH. All rights reserved.

    Bioactive components in rice vary depending on the variety and growing condition. Fat-soluble components such as γ-oryzanol, tocopherols, tocotrienols, carotenoids, and fatty acids were analyzed in brown, sugary brown, red, and black rice varieties using established high-performance liquid chromatography (HPLC) and GC methodologies. In addition, these colored rice varieties were further analyzed using a high-resolution liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS) (LTQ-Orbitrap XL) to identify the [M-H](-) ions of γ-oryzanol, ranging from m/z 573.3949 to 617.4211. The highest content of tocopherols (α-, 1.5; γ-, 0.5 mg/100 g) and carotenoids (lutein 244; trans-β carotene 25 μg/100 g) were observed in black rice; tocotrienols (α-, 0.07; γ-, 0.14 mg/100 g) in red rice, and γ-oryzanol (115 mg/100 g) in sugary brown rice. In all colored rice varieties, the major fatty acids were palmitic (16:0), oleic (18:1n-9), and linoleic (18:2n-6) acids. When the γ-oryzanol components were further analyzed by LC-MS/MS, 3, 10, 8, and 8 triterpene alcohols or sterol ferulates were identified in brown, sugary brown, red, and black rice varieties, respectively. Such structural identification can lead to the elucidation of biological function of each component at the molecular level. Consumption of colored rice rich in beneficial bioactive compounds may be a useful dietary strategy for achieving optimal health.

    Effective strategies to increase dietary intake in older persons with a poor appetite are needed. Previous studies have shown that increasing diet variety may increase dietary intake. This has not been tested in older adults with a poor appetite. We investigated if an increased variety of foods within a cooked meal results in a higher meal energy intake in older women with a poor appetite. This study was a randomized, controlled, cross-over trial among 19 older (>65 years) women with a poor appetite. Two cooked meals of similar weight and energy density (except starch) were served under standardized conditions on two weekdays: a test meal consisting of three different varieties of vegetables, meat or fish, and starch components, and a control meal without variety. Participants ate ad libitum and the actual consumed amounts and their nutritional content were calculated. Data were analyzed by mixed linear models. Average intake in energy was 427 kcal (SD 119) for the test meal with variety and 341 kcal (SD 115) for the control meal without variety. This resulted in a statistically significant (for period effects adjusted) mean difference of 79 kcal (95% CI = 25-134). Total meal intake in grams was also higher for the test meal with variety (48 g, 95% CI = 1-97) but protein intake (g) was not (3.7 g, 95% CI = -1.4 to 8.8). This was consistent for all meal components except starch and within each component three varieties were consumed equally. The results of the present study suggest that increasing meal variety may be an effective strategy to increase energy intake in older adults with a poor appetite. Copyright © 2015 Elsevier Ltd.

    Full Text Available Abstract Background To evaluate the effect of a dietary supplement containing polyunsaturated fatty acids, in association with Humulus lupulus extract, on the quality of sleep using the Leeds sleep evaluation questionnaire (LSEQ in subjects with moderate to severe sleep disorders. Methods Randomized placebo-controlled trial, in a Population-based setting. Participants were adult patients 25 to 65 years old with a chronic primary insomnia who volunteered for the study. The tested intervention consisted of two soft gelatine capsules per day, containing either the dietary supplement (active group or olive oil (placebo group for a month. Subjects could also volunteer for two ancillary studies on melatonin and actigraphy. Evaluation criteria included i perception of the quality of sleep at the end of treatment using the LSEQ questionnaire, ii sleep efficiency measured by one-week actigraphic movement measurement performed before and during the treatment in a subsample of subjects, iii night melatonin and 6 sulfatoxymelatonin (aMT6S urine rates in a subsample of subjects. Results The average of Leeds score was similar in both groups (p = 0.95. A marked improvement in the quality of sleep was observed in both placebo (62% and active (65% group (p = 0.52. The evolution of urinary melatonin, aMT6S, and of the Mel/aMT6S ratio showed no differences between the two groups. Sleep efficiency, as measured by actigraphy, improved similarly in both groups during the treatment period, from 72% to 76% and 75% in the active and placebo group respectively (p = 0.91. Conclusions The dietary supplement had neither effect on the perceived quality of sleep, nor on the melatonin metabolism and sleep-wake cycle. Trial registration: clinical trials.gov:NCT00484497

    Full Text Available Background. Worksite dietary interventions show substantial potential for improving employee health and well-being. The aim of this pilot study was to determine the effect of a worksite nutrition intervention on improving well-being. Methods. Thirty-five university employees participated in a 6-week nutrition intervention. The dietary protocol emphasized the daily consumption of greens, beans/legumes, a variety of other vegetables, fruits, nuts, seeds, and whole grains, referred to as a micronutrient-dense, plant-rich diet. Participants were encouraged to minimize the consumption of refined foods and animal products. Results. Significant improvements in sleep quality, quality of life, and depressive symptoms were found. Conclusions. Findings reveal that a worksite nutrition intervention is effective at improving sleep quality, quality of life, and depressive symptoms with a projected improvement in work productivity and attendance.

    People wearing mandibular two-implant overdentures (IOD) chew food with less difficulty than those wearing conventional complete dentures (CD). However, there is still controversy over whether or not this results in better dietary intake. In this randomized clinical trials (RCT), the amounts of total dietary fiber (TDF), macronutrients, 9 micronutrients, and energy in diets consumed by persons with IOD and CD were compared. Male and female edentate patients ≥ 65 yrs (n = 255) were randomly divided into 2 groups and assigned to receive a maxillary CD and either a mandibular IOD or a CD. One year following prosthesis delivery, 217 participants (CD = 114, IOD = 103) reported the food and quantities they consumed to a registered dietician through a standard 24-hour dietary recall method. The mean and median values of TDF, macro- and micronutrients, and energy consumed by both groups were calculated and compared analytically. No significant between-group differences were found (ps > .05). Despite quality-of-life benefits from IODs, this adequately powered study reveals no evidence of nutritional advantages for independently living medically healthy edentate elders wearing two-implant mandibular overdentures over those wearing conventional complete dentures in their dietary intake at one year following prosthesis delivery (International Clinical Trials ISRCTN24273915).

    Nutrition is an important modifiable factor that affects bone health. Diet is a complex mixture of nutrients and foods that correlate or interact with each other. Dietary pattern approaches take into account contributions from various aspects of diet. Findings from dietary pattern studies could complement those from single-nutrient and food studies on bone health. In this study we aimed to conduct a scoping review of the literature that assessed the impact of dietary patterns (derived with the use of both a priori and data-driven approaches) on bone outcomes, including bone mineral status, bone biomarkers, osteoporosis, and fracture risk. We retrieved 49 human studies up to June 2016 from the PubMed, Embase, and CINAHL databases. Most of these studies used a data-driven method, especially factor analysis, to derive dietary patterns. Several studies examined adherence to a variety of the a priori dietary indexes, including the Mediterranean diet score, the Healthy Eating Index (HEI), and the Alternative Healthy Eating Index (AHEI). The bone mineral density (BMD) diet score was developed to measure adherence to a dietary pattern beneficial to bone mineral density. Findings revealed a beneficial impact of higher adherence to a “healthy” dietary pattern derived using a data-driven method, the Mediterranean diet, HEI, AHEI, Dietary Diversity Score, Diet Quality Index–International, BMD Diet Score, Healthy Diet Indicator, and Korean Diet Score, on bone. In contrast, the “Western” dietary pattern and those featuring some aspects of an unhealthy diet were associated inversely with bone health. In both a priori and data-driven dietary pattern studies, a dietary pattern that emphasized the intake of fruit, vegetables, whole grains, poultry and fish, nuts and legumes, and low-fat dairy products and de-emphasized the intake of soft drinks, fried foods, meat and processed products, sweets and desserts, and refined grains showed a beneficial impact on bone health

    Full Text Available Defining dietary guidelines requires a quantitative assessment of the influence of diet on the development of diseases. The aim of the study was to investigate how dietary patterns were associated with mortality in a general population sample of Switzerland. We included 15,936 participants from two population-based studies (National Research Program 1A (NRP1A and Monitoring of Trends and Determinants in Cardiovascular Disease (MONICA—1977 to 1993 who fully answered a simplified 24-h dietary recall. Mortality data were available through anonymous record linkage with the Swiss National Cohort (follow-up of up to 37.9 years. Multiple correspondence analysis and hierarchical clustering were used to define data-driven qualitative dietary patterns. Mortality hazard ratios were calculated for all-cause, cancer and cardiovascular mortality using Cox regression. Two patterns were characterized by a low dietary variety (“Sausage and Vegetables”, “Meat and Salad”, two by a higher variety (“Traditional”, “High-fiber foods” and one by a high fish intake (“Fish”. Males with unhealthy lifestyle (smokers, low physical activity and high alcohol intake were overrepresented in the low-variety patterns and underrepresented in the high-variety and “Fish” patterns. In multivariable-adjusted models, the “Fish” (hazard ratio = 0.82, 95% CI (0.68–0.99 and “High-fiber foods” (0.85 (0.72–1.00 patterns were associated with lower cancer mortality. In men, the “Fish” (0.73 (0.55–0.97 and “Traditional” (0.76 (0.59–0.98 patterns were associated with lower cardiovascular mortality. In summary, our results support the notion that dietary patterns affect mortality and that these patterns strongly cluster with other health determinants.

    There is growing policy interest in encouraging better dietary choices. We study a nationally-implemented policy - the UK Healthy Start scheme - that introduced vouchers for fruit, vegetables and milk. We show that the policy has increased spending on fruit and vegetables and has been more effective than an equivalent-value cash benefit. We also show that the policy improved the nutrient composition of households' shopping baskets, with no offsetting changes in spending on other foodstuffs. Copyright © 2018 The Authors.

    2010-06-01

    There is a rapid change in our overall lifestyle due to impact of globalization. Every day hasty life has forced consumers to be dependent upon fast foods, which contain meagre amount of dietary fibre. Non-starch polysaccharides and resistant oligosaccharides, lignin, substances associated with NSP and lignin complex in plants, other analogous carbohydrates, such as resistant starch and dextrins, and synthesized carbohydrate compounds, like polydextrose are categorized as dietary fibre. They are mostly concentrated in cereals, pulses, fruits and vegetables. It has been proclaimed that daily dietary fibre intake helps in prevention of many nutritional disorders like gut related problems, cardiovascular diseases, type 2 diabetes, certain types of cancer and obesity. Meat is generally lacking this potential ingredient, which could be incorporated while products processing to make them more healthful. Various fibre rich sources have been attempted in different products attributed to their technological and health benefits and many are in the queue to be used in a variety of meat products. Selection of appropriate fibre rich ingredients and their proper incorporation can improve health image of meat products.

  3. Lessons from the war on dietary fat.

    Conventional dietary guidelines put forth by health care institutions and providers for the past 40 years have stressed the importance of reducing the amount of dietary fat consumed. Such a diet is purported to mitigate metabolic risk factors and optimize the ability to achieve or maintain a healthy body weight. However, over the past 35 years obesity rates in the United States have risen dramatically though the level of dietary fat consumed by U.S. adults has fallen. This review examines the potential reasons for this paradox. Various meta-analyses, controlled trials, and cohort studies have demonstrated that reducing dietary fat intake provides for very little weight loss unless accompanied by equal or greater reductions in total energy intake. Due to both psychological (e.g., the tendency for people to eat more of what they consider low fat) and physiological (e.g., the low satiety that accompanies carbohydrate intake) factors, reducing total caloric intake while simultaneously reducing fat intake is a difficult challenge. Further, reductions in total carbohydrate intake, increases in protein intake, and adoption of a Mediterranean diet seem to be more effective in inducing weight loss than reductions in fat intake. Traditional claims that simply reducing dietary fat will improve metabolic risk factors are also not borne out by research. There is some evidence that replacing dietary saturated fat with unsaturated fat may improve metabolic risk factors, but that research is not conclusive. • Over the past 40 years, Americans have decreased the percentage of calories they get from dietary fat while rates of overweight and obesity have risen dramatically. • It appears that a decrease in total dietary fat in ad libitum diets may induce a very small decrease in body weight. • Evidence suggests that reductions in total dietary fat intake often occur in conjunction with an increase in total caloric intake. • It seems reasonable to conclude that guiding the

    College students are in transition from adolescence to adulthood, and it has been reported that they show poor dietary habits. This study was conducted to compare body image perception, nutrition knowledge, dietary attitudes, dietary habits, and health-related lifestyles between Korean college students (KCS) and Mongolian college students (MCS). Subjects were 314 KCS and 280 MCS. The data includes results of self-administered questionnaires; statistical analysis was performed using the SPSS 23.0 program. With regards to body image perception, KCS perceived themselves to be fatter on current body image than ideal body image compared to MCS; 64.0% of KCS and 34.6% of MCS desired to be thinner. Total score of nutrition knowledge in KCS (17.0) was significantly higher compared to MCS (8.4) ( P correlation with dietary attitudes in MCS ( P mobile phone usage ( P < 0.001), compared to MCS. This study suggests that development of nutrition education program which is effective and proper is required to improve healthy dietary habits among college students of both countries. Essential contents should include acquirement of nutrition knowledge and a motivation for its application to actual life for KCS, and improvement of healthy dietary habits for MCS.

    Full Text Available Background: The effects of capsaicin on obesity and glucose homeostasis are still controversial and the mechanisms underlying these effects remain largely unknown. This study aimed to investigate the potential relationship between the regulation of obesity and glucose homeostasis by dietary capsaicin and the alterations of gut microbiota in obese diabetic ob/ob mice.Methods: The ob/ob mice were subjected to a normal, low-capsaicin (0.01%, or high-capsaicin (0.02% diet for 6 weeks, respectively. Obesity phenotypes, glucose homeostasis, the gut microbiota structure and composition, short-chain fatty acids, gastrointestinal hormones, and pro-inflammatory cytokines were measured.Results: Both the low- and high-capsaicin diets failed to prevent the increase in body weight, adiposity index, and Lee's obesity index. However, dietary capsaicin at both the low and high doses significantly inhibited the increase of fasting blood glucose and insulin levels. These inhibitory effects were comparable between the two groups. Similarly, dietary capsaicin resulted in remarkable improvement in glucose and insulin tolerance. In addition, neither the low- nor high-capsaicin diet could alter the α-diversity and β-diversity of the gut microbiota. Taxonomy-based analysis showed that both the low- and high-capsaicin diets, acting in similar ways, significantly increased the Firmicutes/Bacteroidetes ratio at the phylum level as well as increased the Roseburia abundance and decreased the Bacteroides and Parabacteroides abundances at the genus level. Spearman's correlation analysis revealed that the Roseburia abundance was negatively while the Bacteroides and Parabacteroides abundances were positively correlated to the fasting blood glucose level and area under the curve by the oral glucose tolerance test. Finally, the low- and high-capsaicin diets significantly increased the fecal butyrate and plasma total GLP-1 levels, but decreased plasma total ghrelin, TNF-α, IL-1

    Development and promotion of dietary guidelines is one of the key activities outlined in the National Plan of Action for Nutrition of Malaysia for the prevention of nutrition-related disorders. The first official Malaysian Dietary Guidelines (MDG) was published in 1999 and was thoroughly reviewed and launched on 25 March 2010. The new MDG 2010 is a compilation of science-based nutrition and physical activity recommendations. These guidelines form the basis of consistent and scientifically sound nutrition messages for the public. There are 14 key messages and 55 recommendations, covering the whole range of food and nutrition issues, from importance of consuming a variety of foods to guidance on specific food groups, messages to encourage physical activities, consuming safe food and beverages and making effective use of nutrition information on food labels. The MDG also has an updated food pyramid. Various efforts have been made to ensure that the revised MDG is disseminated to all stakeholders. The Ministry of Health has organised a series of workshops for nutritionists and other health care professionals, and the food industry. In collaboration with other professional bodies and the private sector, the Nutrition Society of Malaysia has been promoting the dissemination and usage of the MDG to the public through a variety of formats and channels. These include the publication of a series of leaflets, educational press articles, educational booklets, as well as through educational activities for children. It is imperative to monitor the usage and evaluation of these dietary messages.

    Dietary inclusion of antibiotics as growth promoters (AGPs) in poultry production has been applied for decades worldwide, but recently AGPs have been banned due to the negative consequences for health and food safety. Soybean oligosccharide (SOS) derived from soybean meal extract is one of natural compound without carrying-over the residue to product and is consumer’s health friendly. The purpose of the present study was to evaluate dietary inclusion of SOS on broiler meat quality. A total of 120 broilers of 7-day-old were allocated into 3 treatments with 4 replications (10 birds each) in completely randomized design. Treatments applied were D1: diet without SOS, D2: D1 plus 0.15% SOS, and D3: D1 plus 0.30% SOS. Intestinal lactic acid bacteria (LAB), protein digestibility, meat protein and fat depositions, and meat cholesterol were the parameters observed. Data were statistically tested using analysis of variance and Duncan test. Dietary SOS inclusion at 0.30% (D3) significantly (P<0.05) increased LAB population (7.21x104 cfu/g), protein digestibility (72.80%), and meat protein deposition (90.83 g/bird), but it decreased meat fat (8.27 g/bird) and meat cholesterol (37.28 mg/100 g). In conclusion, dietary SOS inclusion at 0.30% improves meat quality of broiler based on the increase in meat protein deposition with lower fat and cholesterol.

    A low Omega-3 Index (eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in erythrocytes) is associated with cardiac, cerebral, and other health issues. Intake of EPA and DHA, but not of alpha-linolenic acid (ALA), increases the Omega-3 Index. We investigated bioavailability, safety, palatability and tolerability of EPA and DHA in a novel source: a variety of sausages. We screened 96 healthy volunteers, and recruited 44 with an Omega-3 Index Omega-3 Index increased from 4.18 ± 0.54 to 5.72 ± 0.66% ( p Omega-3 Index per intake of EPA and DHA we observed was higher than for other sources previously studied, indicating superior bioavailability. As increasing production of EPA and DHA is difficult, improvements of bioavailability can facilitate reaching the target range for the Omega-3 Index (8-11%).

    Because farmers' markets include a variety of fruits and vegetables, shopping at farmers' markets would likely improve diet quality among low-income consumers, as well as promote sustainable direct farm-to-consumer business models. However, not much is known about how to promote farmers' market shopping among low-income consumers. Therefore, the purpose of the present paper was to examine barriers to and facilitators of shopping at farmers' markets and associations between shopping at farmers' markets and self-reported dietary behaviours (fruit and vegetable, sugar-sweetened beverage and fast-food consumption) and BMI. Cross-sectional analyses of associations between farmers' market shopping frequency, awareness of markets, access to markets, dietary behaviours and BMI.

Between April and July 2013, Supplemental Nutrition Assistance Program (SNAP) participants (n 205) completed a quantitative survey. Barriers to shopping at farmers' markets included does not accept SNAP/electronic benefit transfer, out of the way and lack of transportation. Farmers' market shopping was associated with awareness of farmers' markets (estimate =0·18 (se 0·04), Pmarket shopping (estimate =1·06 (se 0·32), P=0·001). Our study is one of the first to examine SNAP participants' farmers' market shopping, distance to farmers' markets and dietary behaviours. Barriers to shopping at farmers' markets and increasing awareness of existing markets should be addressed in future interventions to increase SNAP participants' use of farmers' markets, ultimately improving diet quality in this high-risk group.

    Food-Based Dietary Guidelines (FBDG) are usually accompanied by an image for dissemination and implementation. to design and validate an image to represent the variety and proportions of the new Chilean dietary guidelines, include foods high in critical nutrients that should be avoided and physical activity guidelines. a panel of experts tested seven graphics and selected three that were validated with 12 focus groups of people aged 10-14 and 20-40 years, of both sexes, from different socioeconomic groups and from both rural and urban areas. We analyzed the perception of variety and proportions of the food groups for daily intake and motivation for action in diet and physical activity. We utilized the METAPLAN method used previously in the validation of FBDG. the final image was a circle that showed the variety and proportions of each food group for daily consumption (in pictures), included physical activity guidelines in a strip around the middle of the circle and a rectangle towards of bottom of the image with examples of foods high in critical nutrients in black and white. The chosen picture was modified using input from participants and validated with three additional focus groups, improving its understanding and acceptance. most participants understood that the image represented the relationship between healthy eating and daily physical activity, correctly identifying the food groups for which increased intake was suggested and those groups in which intake should be reduced or avoided.

    To (i) determine differences in the availability of variety of fruits and vegetables (F&V) at home by food security status; and (ii) examine the inter-associations between food security status, availability of variety of F&V at home and frequency of F&V intake, among low-income pregnant women. Design/Setting Participants were interviewed to collect food security status, home availability of variety of F&V and frequency of F&V intake. Bivariate analyses, multivariate regression and exploratory mediation analyses were conducted using IBM SPSS Statistics version 23.0 and the PROCESS macro. Low-income pregnant women (n 198) were interviewed if they were ≥18 years of age, in the second trimester of pregnancy, and spoke English or Spanish. Low/very low food security was found among 43 % of participants. Compared with fully food-secure participants, very low food-secure participants reported a lower variety of fruits (P=0·028) and vegetables (P=0·058) available at home. Mediation analyses indicated that through home availability of variety of fresh F&V, food security status was associated with the daily intake of F&V (indirect effect (95 % CI): fresh fruits, -0·039 (-0·074, -0·013); fresh vegetables, -0·048 (-0·083, -0·023)). As food security worsened, the available variety of fresh F&V decreased, which was associated with lower intake. The study highlights the interlink between food security, home food environment and diet quality, and the importance of nutrition education intervention to promote a healthy home food environment and improved pregnancy outcomes among low-income women.

    Chronic low-grade inflammation plays a pivotal role in the pathogenesis of obesity, due to its associated chronic diseases such as type II diabetes, cardiovascular diseases, pulmonary diseases and cancer. Thus, targeting inflammation is an attractive strategy to counter the burden of obesity-induced health problems. Recently, food-derived bioactive compounds have been spotlighted as a regulator against various chronic diseases due to their low toxicity, as opposed to drugs that induce severe side effects. Here we describe the beneficial effects of dietary anthocyanins on obesity-induced metabolic disorders and inflammation. Red cabbage microgreen, blueberry, blackcurrant, mulberry, cherry, black elderberry, black soybean, chokeberry and jaboticaba peel contain a variety of anthocyanins including cyanidins, delphinidins, malvidins, pelargonidins, peonidins and petunidins, and have been reported to alter both metabolic markers and inflammatory markers in cells, animals, and humans. This review discusses the interplay between inflammation and obesity, and their subsequent regulation via the use of dietary anthocyanins, suggesting an alternative dietary strategy to ameliorate obesity and obesity associated chronic diseases.

  13. Inhibition of Endothelial p53 Improves Metabolic Abnormalities Related to Dietary Obesity

    Full Text Available Accumulating evidence has suggested a role for p53 activation in various age-associated conditions. Here, we identified a crucial role of endothelial p53 activation in the regulation of glucose homeostasis. Endothelial expression of p53 was markedly upregulated when mice were fed a high-calorie diet. Disruption of endothelial p53 activation improved dietary inactivation of endothelial nitric oxide synthase that upregulated the expression of peroxisome proliferator-activated receptor-γ coactivator-1α in skeletal muscle, thereby increasing mitochondrial biogenesis and oxygen consumption. Mice with endothelial cell-specific p53 deficiency fed a high-calorie diet showed improvement of insulin sensitivity and less fat accumulation, compared with control littermates. Conversely, upregulation of endothelial p53 caused metabolic abnormalities. These results indicate that inhibition of endothelial p53 could be a novel therapeutic target to block the vicious cycle of cardiovascular and metabolic abnormalities associated with obesity.

    Energy drink consumption has been associated with a variety of health risk behaviours, yet little research has explored the relationship between energy drinks and dietary behaviours of emerging adults. Therefore, the purpose of this study was to explore the relationship between energy drink consumption and dietary behaviours among energy drink users and non-users within a sample of college youth. College freshmen (n = 585, m age = 18.7 years; 47% non-Hispanic White, 20.9% Hispanic, 25.5% Asian, 2.7% non-Hispanic Black and 4.4% other; 56% female), at a large, southwest university self-reported their energy drink consumption in the past week and a variety of dietary behaviours, including past week soda, diet soda, pre-packaged salty snacks, pre-packaged sweet snacks, fast food, restaurant food, frozen food, fruits, vegetables, milk and breakfast consumption. Linear regression analyses were run to determine associations between energy drink consumption and dietary behaviour among users and non-users of energy drinks. Analyses controlled for gender, race/ethnicity and body mass index (BMI). Overall, 17.5% of students had consumed energy drinks in the past week. Energy drink users were more likely to be male, White and have a greater BMI. Students also reported low past week intake of fruits, vegetables, milk and breakfast. Past week energy drink consumption was associated with increased soda and frozen meal consumption. Given a rapidly expanding energy drink market, future dietary interventions among college youth may want to consider the implications of energy drinks, as results of this study suggest consumption of these beverages is associated with unhealthy dietary behaviours and a greater BMI. © Royal Society for Public Health 2015.

    2017-01-01

    Full Text Available Contaminants (or pollutants that affect human health have become an important issue, spawning a myriad of studies on how to prevent harmful contaminant-induced effects. Recently, a variety of biological functions of natural dietary compounds derived from consumed foods and plants have been demonstrated in a number of studies. Natural dietary compounds exhibited several beneficial effects for the prevention of disease and the inhibition of chemically-induced carcinogenesis. Contaminant-induced toxicity and carcinogenesis are mostly attributed to the mutagenic activity of reactive metabolites and the disruption of normal biological functions. Therefore, the metabolic regulation of hazardous chemicals is key to reducing contaminant-induced adverse health effects. Moreover, promoting contaminant excretion from the body through Phase I and II metabolizing enzymes is also a useful strategy for reducing contaminant-induced toxicity. This review focuses on summarizing the natural dietary compounds derived from common dietary foods and plants and their possible mechanisms of action in the prevention/suppression of contaminant-induced toxicity.

    To examine the opinions of stakeholders on strategies to improve dietary quality of Supplemental Nutrition Assistance Program (SNAP) participants. Participants answered a thirty-eight-item web-based survey assessing opinions and perceptions of SNAP and programme policy changes. Survey of 522 individuals with stakeholder interest in SNAP, conducted in October through December 2011. The top three barriers to improving dietary quality identified were: (i) unhealthy foods marketed in low-income communities; (ii) the high cost of healthy foods; and (iii) lifestyle challenges faced by low-income individuals. Many respondents (70 %) also disagreed that current SNAP benefit levels were adequate to maintain a healthy diet. Stakeholders believed that vouchers, coupons or monetary incentives for purchasing healthful foods might have the greatest potential for improving the diets of SNAP participants. Many respondents (78 %) agreed that sodas should not be eligible for purchases with SNAP benefits. More than half (55 %) believed retailers could easily implement such restrictions. A majority of respondents (58 %) agreed that stores should stock a minimum quantity of healthful foods in order to be certified as a SNAP retailer, and most respondents (83 %) believed that the US Department of Agriculture should collect data on the foods purchased with SNAP benefits. Results suggest that there is broad stakeholder support for policies that align SNAP purchase eligibility with national public health goals of reducing food insecurity, improving nutrition and preventing obesity.

    There is currently many over the counter products on the market that exert nutritional or physiological effects on the human body. The differences between dietary supplements and non-prescription drugs are however poorly understood by the average consumer and may thus affect their expectations as to the desired effect produced on the body. To evaluate patients' knowledge and attitudes towards dietary supplements as compared to non-prescription drugs. Subjects were 335 patients of the Mazowiecki Voivodeship Hospital in Warsaw, Poland. The data were collected from a face-to-face interview using a single and multiple choice questionnaire with 10 questions on dietary supplements. Statistical analysis used the Chi-square (χ2) test. The majority of respondents were found to be familiar with the term 'dietary supplements', but had difficulties in classifying these products into appropriate categories. Over 55% do not consider dietary supplements to be foodstuffs and more than 40% considered such products to be drugs. Most respondents thought that the main purpose of taking dietary supplements is to improve nutrition, but over one third expected them to also treat disease. Over 70% declared taking notice to which category the non-prescription products they bought belongs to ie. whether non-prescription drugs (medicinal products) or dietary supplements. Many patients mistakenly believe that dietary supplements are drugs and can be used to treat disease and health disorders. dietary supplements, opinion on dietary supplements, nutrition, dietary supplement vs. medicinal product.

    Dietary fibre is that part of plant material in the diet which is resistant to enzymatic digestion which includes cellulose, noncellulosic polysaccharides such as hemicellulose, pectic substances, gums, mucilages and a non-carbohydrate component lignin. The diets rich in fibre such as cereals, nuts, fruits and vegetables have a positive effect on health since their consumption has been related to decreased incidence of several diseases. Dietary fibre can be used in various functional foods like bakery, drinks, beverages and meat products. Influence of different processing treatments (like extrusion-cooking, canning, grinding, boiling, frying) alters the physico- chemical properties of dietary fibre and improves their functionality. Dietary fibre can be determined by different methods, mainly by: enzymic gravimetric and enzymic-chemical methods. This paper presents the recent developments in the extraction, applications and functions of dietary fibre in different food products.

  3. Dietary supplementation with Lactobacilli improves emergency granulopoiesis in protein-malnourished mice and enhances respiratory innate immune response.

    Matias Herrera

    Full Text Available This work studied the effect of protein malnutrition on the hemato-immune response to the respiratory challenge with Streptococcus pneumoniae and evaluated whether the dietary recovery with a probiotic strain has a beneficial effect in that response. Three important conclusions can be inferred from the results presented in this work: a protein-malnutrition significantly impairs the emergency myelopoiesis induced by the generation of the innate immune response against pneumococcal infection; b repletion of malnourished mice with treatments including nasally or orally administered Lactobacillus rhamnosus CRL1505 are able to significantly accelerate the recovery of granulopoiesis and improve innate immunity and; c the immunological mechanisms involved in the protective effect of immunobiotics vary according to the route of administration. The study demonstrated that dietary recovery of malnourished mice with oral or nasal administration of L. rhamnosus CRL1505 improves emergency granulopoiesis and that CXCR4/CXCR12 signaling would be involved in this effect. Then, the results summarized here are a starting point for future research and open up broad prospects for future applications of probiotics in the recovery of immunocompromised malnourished hosts.

    A field study was conducted to evaluate crop growth and seed yield performance of Brassica varieties under Rainfed conditions. The varieties, included in the study, were BSA, Zafar-2000, Pakola, Con.1, Con.2, Abaseen, Rainbow, SPS-5, Bard-1, and KJ-119. KJ-119 (2500.0 KG/HA) among Brassica juncea L. varieties and Abaseen (2425.9 kg/ha) among Brassica napusL. Varieties produced with maximum seed yield as compared to rest of varieties. Significantly, minimum seed yield was observed in check variety BSA. The significant difference in seed yield of Brassica varieties, Abaseen and KJ 119, was attributed to improve yield components over other varieties. Maximum pods per plant and seeds per pod led these varieties to attain maximum yield. Inspite of weather variations existence during years 2007-09,the same varieties produced with maximum seed yield.

  7. On the mechanism by which dietary nitrate improves human skeletal muscle function

    Charles eAffourtit

    2015-07-01

    Full Text Available Inorganic nitrate is present at high levels in beetroot and celery, and in green leafy vegetables such as spinach and lettuce. Though long believed inert, nitrate can be reduced to nitrite in the human mouth and, further, under hypoxia and/or low pH, to nitric oxide. Dietary nitrate has thus been associated favourably with nitric-oxide-regulated processes including blood flow and energy metabolism. Indeed, the therapeutic potential of dietary nitrate in cardiovascular disease and metabolic syndrome – both ageing-related medical disorders – has attracted considerable recent research interest. We and others have shown that dietary nitrate supplementation lowers the oxygen cost of human exercise, as less respiratory activity appears to be required for a set rate of skeletal muscle work. This striking observation predicts that nitrate benefits the energy metabolism of human muscle, increasing the efficiency of either mitochondrial ATP synthesis and/or of cellular ATP-consuming processes. In this mini-review, we evaluate experimental support for the dietary nitrate effects on muscle bioenergetics and we critically discuss the likelihood of nitric oxide as the molecular mediator of such effects.

    Most work sites engage in some form of health promotion programming designed to improve worker health and reduce health care costs. Although these programs have typically been delivered through combinations of seminars and print materials, workplace health promotion programs are increasingly being delivered through the Internet. The purpose of this research was to evaluate the effectiveness of a Web-based multimedia health promotion program for the workplace, designed to improve dietary practices, reduce stress, and increase physical activity. Using a randomized controlled trial design with pretest-posttest comparisons within each group, 419 employees of a human resources company were randomly assigned to the Web-based condition or to a condition that provided print materials on the same topics. All subjects were assessed at pretest and posttest through an online questionnaire containing multiple measures of health behavior and attitudes. The test period was 3 months. Questionnaire data were analyzed mainly by analysis of covariance and t tests. Retention rates were good for both groups-85% for the Web-based group and 87% for the print group. Subjects using the Web-based program performed significantly better than the print group on Attitudes Toward a Healthful Diet (F(1,415) = 7.104, P = .008) and Dietary Stage of Change (F(1,408) = 6.487, P = .01), but there were no significant group differences on the five other dietary measures. Both groups also showed improvement from pretest to posttest on most dietary measures, as indicated by significant t tests. Within the Web-based group, dosage analyses showed significant effects of the number of times the subject accessed the program on measures of Dietary Self-Efficacy (F(2,203) = 5.270, P = .003), Attitudes Toward a Healthful Diet (F(2,204) = 2.585, P = .045), and Dietary Stage of Change (F(2,200) = 4.627, P = .005). No significant differences were found between the two groups on measures of stress or physical

    Full Text Available Researches were carried out on horse populations of Nonius variety and Ardennes breedfrom Izvin Stud, farm that belongs to the Forestry Direction Timiş. In Romania, Noniusvariety built up at the Mezohegyes Stud in Hungary was imported at Bonţida and Ruşeţu inyear 1920. In year 1940, the two types of Nonius were blended and were raised together atthe Parţa Stud, called later Pădureni Stud. There stayed until year 1967 when the horsepopulation was moved to the Izvin Stud, where is raised together with the Ardennes horseimported from Hungary as well. The aim of the present study was to attempt to optimize thegenetic improvement actions of the horse population from Nonius variety and Ardennesbreed raised at the Izvin Stud. For Nonius variety the main genetic improvement objectiveswere set up as being the improvement of the reproduction traits, correction of the gait inhorses, increasing the energetic capacity, temperament and nervous impulse, as well asother conformation traits. For the Ardennes breed the main genetic improvement objectiveswere considered to be the increase of the constitutional strength, correction of the gait andimprovement of the reproduction indices. The study was ended with a number ofconclusions and recommendations.

    Dietary fiber consists of the structural and storage polysaccharides and lignin in plants that are not digested in the human stomach and small intestine. A wealth of information supports the American Dietetic Association position that the public should consume adequate amounts of dietary fiber from a variety of plant foods. Recommended intakes, 20-35 g/day for healthy adults and age plus 5 g/day for children, are not being met, because intakes of good sources of dietary fiber, fruits, vegetables, whole and high-fiber grain products, and legumes are low. Consumption of dietary fibers that are viscous lowers blood cholesterol levels and helps to normalize blood glucose and insulin levels, making these kinds of fibers part of the dietary plans to treat cardiovascular disease and type 2 diabetes. Fibers that are incompletely or slowly fermented by microflora in the large intestine promote normal laxation and are integral components of diet plans to treat constipation and prevent the development of diverticulosis and diverticulitis. A diet adequate in fiber-containing foods is also usually rich in micronutrients and nonnutritive ingredients that have additional health benefits. It is unclear why several recently published clinical trials with dietary fiber intervention failed to show a reduction in colon polyps. Nonetheless, a fiber-rich diet is associated with a lower risk of colon cancer. A fiber-rich meal is processed more slowly, which promotes earlier satiety, and is frequently less calorically dense and lower in fat and added sugars. All of these characteristics are features of a dietary pattern to treat and prevent obesity. Appropriate kinds and amounts of dietary fiber for the critically ill and the very old have not been clearly delineated; both may need nonfood sources of fiber. Many factors confound observations of gastrointestinal function in the critically ill, and the kinds of fiber that would promote normal small and large intestinal function are usually

  14. Should states and local governments regulate dietary supplements?

    Science.gov (United States)

    Starr, Ranjani

    2016-01-01

    Federal regulation of dietary supplements in the United States is governed by the Dietary Supplement Health and Education Act of 1994. The law has been criticized as weak and ineffective. Alarming research has emerged demonstrating that supplements may be mislabelled, contaminated, adulterated with dangerous or unknown compounds, or sold at toxic doses. As a result, the health community has raised concerns about the safety and quality of dietary supplements. Increased federal oversight is an important avenue for improving supplement safety; however, states and local governments may also pursue strategies to strengthen the overall regulatory control of dietary supplements. States and local governments have substantial experience in regulating other products that pose a risk to public health, such as tobacco. Additionally, much has been learned about the tactics the tobacco industry has employed to protect its interests. Lessons learned may be applied to new regulatory efforts aimed at improving the safety of dietary supplements at the state and local levels. Copyright © 2015 John Wiley & Sons, Ltd.

    Poor eating habits among young adults are a public health concern. This survey examined the eating habits of undergraduate university students in Finland. We assessed students' dietary intake of a variety of food groups, their adherence to international dietary guidelines (whole sample and by gender), and the associations between importance of eating healthy and dietary guidelines adherence (whole sample and by gender). During the 2013-2014 academic year, 1,189 undergraduate students enrolled at the University of Turku in southwestern Finland completed an online self-administered questionnaire. Students reported their eating habits of 12 food groups, the number of daily servings of fruits/vegetables they consume and how important it is for them to eat healthy. For dietary adherence recommendations, we employed WHO guidelines. Chi-square statistic tested the differences in dietary guidelines adherence between males and females and also the associations between the gradients of importance of healthy eating and the self reported eating habits for each of the food groups, for the whole sample and by gender. We observed high levels of dietary adherence (>70%) for most of the 'unhealthy food' items (cake/cookies, snacks, fast food/canned food, and lemonade/soft drinks), and moderate adherence for most of the 'healthy food' items (>50%) (dairy/dairy products, fruit/vegetables servings/day, fresh fruit, salads/raw vegetables and cereal/cereal products). Fish/seafood, meat/sausage products and cooked vegetables had levels healthy food' items (p≤0.001), whereas men had better adherence for sweets (difference=12.8%, p≤0.001), lemonade/soft drinks (difference=16.7%, p≤0.001) and fish/seafood (difference=6.6%, p=0.040) compared to women. Most students considered important to eat healthy (78.8%). The importance of eating healthy was significantly associated with adherence for all food groups besides sweets and cake/cookies. These associations remained significant for women

    In the approximately 70 year-old history of induced mutations, there are many examples on the development of new and valuable alteration in plant characters significantly contributing to increased yield potential of specific crops. However, knowledge on the success of induced mutations in crop improvement among geneticists and breeders is usually limited to species of their interest. The present paper contains a comprehensive list of officially released mutant varieties, based on information from plant breeders. The number of mutant varieties officially released and recorded in the FAO/IAEA Mutant Varieties Database before the end of 2000 is 2,252. Almost half of these varieties have been released during the last 15 years. Considering a significant delay in the dissemination of information on newly released varieties and difficulties in the collection of such data, there has been a renaissance in the use of mutation techniques in crop improvement. At the demand of geneticists, plant breeders, and more recently molecular geneticists, for information on released mutant varieties of specific crops, the MVD was transferred to the web site of the FAO/IAEA Joint Division. The MVD will be available on our web pages early in 2001. (author)

    This experiment was conducted to evaluate the effects of dietary inclusion of Bacillus licheniformis on laying performance, egg quality, antioxidant enzyme activities, and intestinal barrier function of laying hens. Hy-Line Variety W-36 hens (n = 540; 28 wk of age) were randomized into 6 groups, each group with 6 replications (n = 15). The control group received the basal diet formulated with maize and soybean meal. The treatment groups received the same basal diets supplemented with 0.01, 0.02, 0.03, 0.06, and 0.09% Bacillus licheniformis powder (2 × 10(10) cfu/g) for an 8-wk trial. The results showed that dietary supplementation with 0.01 and 0.03% B. licheniformis significantly increased egg production and egg mass. However, no significant differences were observed in egg weight, feed consumption, and feed conversion efficiency among the 6 groups. Supplementation with different levels of B. licheniformis was found to be effective in improvement of egg quality by increasing egg shell thickness and strength. Compared with control, d-lactate content, diamine oxidase activity, and adrenocorticotropic hormone level in serum decreased significantly, and the level of estradiol and follicle-stimulating hormone increased significantly in plasma of all the experimental groups. Dietary supplementation with B. licheniformis increased the intestinal villus height and reduced the crypt depth. In conclusion, dietary inclusion of B. licheniformis could improve laying performance and egg quality significantly in a dose-dependent manner by decreasing the stress response, upregulating the growth hormone, and improving intestinal health.

    Jute is the important agricultural and industrial resource of Bangladesh for earning foreign currency. Seeds of the widely cultivated variety, CVL-1 were treated with 4 mM to 20mM of sodium azide (NaN3). The treated seeds were grown in M1 to M10 generations. A single plant (selection number C-278) was selected from M2 segregating population on the basis of early sowing potential and late flowering. Ten fiber quality characters were tested and it was found that the fiber quality of the mutant had been improved. Hence, the mutagen sodium azide showed extra potentiality to induce fiber quality characters of jute. The strain C-278 was also tested through Preliminary, Advanced, Zonal Yield Trial and Farmers field trial at different locations of the jute growing area in Bangladesh. The field evaluation team of the National Seed Board (NSB) visited most of the trials and reported that at early sowing and overall performance of the strain C-278 was found best than that of the mother variety. Besides these the strain produced 7.5% and 20% higher fiber yield than the mother variety CVL-1 and a local cultivar, D-154, respectively. After evaluation of the Technical Committee of NSB recommended that the strain C-278 may be released as a variety. The National Seed Board released the strain C-278 as a National jute variety under the name Binadeshipat-2 for cultivation in Bangladesh

    Children are encouraged to eat a specific amount of fruits and vegetables to optimize health. The purpose of this study was to assess whether consumption of a variety of fruits and vegetables, respectively, was associated with a greater diet quality among preschool-aged children. Analyses were performed using a cross-sectional, nationally representative sample of US children. Dietary intakes from 24-h dietary recalls of two-five year old children ( n  = 2595) in 2005-2010 NHANES were examined. Diet quality was evaluated using MyPlate equivalents and the Healthy Eating Index 2010 (HEI-2010). Variety categories were determined based on children's fruit, fruit juice, and vegetable consumption on the recalled day. Differences in diet quality were examined using t -tests. Variety of fruits and vegetables was linked to higher overall diet quality. Children who consumed whole fruit had better diet quality scores for total fruit, whole fruit, whole grains, dairy, seafood, refined grains, sodium, and empty calories ( P  ≤ 0.018). Significantly higher HEI-2010 scores for total fruit, whole fruit, fatty acids, sodium, and empty calories, but a lower dairy HEI-2010 score, were identified in children who drank fruit juice ( P  ≤ 0.038). Vegetable consumption was significantly associated with higher total vegetables, greens/beans, and empty calories, but a lower sodium score ( P  ≤ 0.027). Children who consumed whole fruit, fruit juice and non-starchy vegetables ( P  ≤ 0.017), but not white potatoes, had significantly higher total HEI-2010 scores. Reinforcing fruit and 100% fruit juice consumption may indirectly support healthier diets among children. However, underlying associations between fruit and vegetable intakes and overall diet quality should be examined further.

    2009-01-01

    Although type 2 diabetes is determined primarily by lifestyle and genes, dietary composition may affect both its development and complications. Dietary fat is of particular interest because fatty acids influence glucose metabolism by altering cell membrane function, enzyme activity, insulin signaling, and gene expression. This paper focuses on the prevention of type 2 diabetes and summarizes the epidemiologic literature on associations between types of dietary fat and diabetes risk. It also summarizes controlled feeding studies on the effects of dietary fats on metabolic mediators, such as insulin resistance. Taken together, the evidence suggests that replacing saturated fats and trans fatty acids with unsaturated (polyunsaturated and/or monounsaturated) fats has beneficial effects on insulin sensitivity and is likely to reduce risk of type 2 diabetes. Among polyunsaturated fats, linoleic acid from the n-6 series improves insulin sensitivity. On the other hand, long-chain n-3 fatty acids do not appear to improve insulin sensitivity or glucose metabolism. In dietary practice, foods rich in vegetable oils, including non-hydrogenated margarines, nuts, and seeds, should replace foods rich in saturated fats from meats and fat-rich dairy products. Consumption of partially hydrogenated fats should be minimized. Additional controlled, long-term studies are needed to improve our knowledge on the optimal proportion of different types of fats to prevent diabetes.

    With the increasing use of unregulated dietary supplements, athletes are at continued risk from adverse medical events and inadvertent doping. A review of Clinical Key, MEDLINE, and PubMed databases from 2012 to 2017 was performed using search terms, including dietary supplement, contamination, doping in athletes, inadvertent doping, and prohibited substances. The references of pertinent articles were reviewed for other relevant sources. Clinical review. Level 3. Poor manufacturing processes and intentional contamination with many banned substances continue to occur in dietary supplements sold in the United States. Certain sectors, such as weight loss and muscle-building supplements, pose a greater threat because they are more likely to be contaminated. Athletes will continue to be at risk for adverse events and failed doping tests due to contaminated dietary supplements until legislation changes how they are regulated. In the interim, there are several steps that can be taken to mitigate this risk, including improved education of medical staff and athletes and use of third party-certified products.

    In recent years, concern has been raised over honey bee colony losses, and also among wild bees there is evidence for extinctions and range contractions in Europe and North America. Pesticides have been proposed as a potential cause of this decline. Bees are exposed simultaneously to a variety of agrochemicals, which may cause synergistically detrimental impacts, which are incompletely understood. We investigated the toxicity of the fungicide imazalil in mixture with four common insecticides: fipronil (phenylpyrazoid), cypermethrin (pyrethroid), thiamethoxam, and imidacloprid (neonicotinoids). Ergosterol biosynthesis inhibitor (EBI) fungicides like imazalil can inhibit P450 detoxification systems in insects and therefore fungicide - insecticide co-occurrence might produce synergistic toxicity in bees. We assessed the impact of dietary fungicide - insecticide mixtures on the mortality and feeding rates of laboratory bumble bees (Bombus terrestris L.). Regarding mortality, imazalil synergised the toxicity of fipronil, cypermethrin and thiamethoxam, but not imidacloprid. We found no synergistic effects on feeding rates. Our findings suggest that P450-based detoxification processes are differentially important in mitigating the toxicity of certain insecticides, even those of the same chemical class. Our evidence that cocktail effects can arise in bumble bees should extend concern about the potential impacts of agrochemical mixtures to include wild bee species in farmland. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

    Full text: The large scale cultivation of soybean in India (nearly 2 million ha at present) with yellow seeded varieties is a comparatively recent development. In early times, black seeded soybean was grown on a limited area, under local names like ''Bhat'', ''Bhatmash'', ''Kalitur'' or ''Kala Hulga''. These indigenous varieties are characterised by small black seeds, the ability to thrive well under suboptimal conditions, good seed germinability and organoleptic suitability for certain indigenous food preparations. However, they show low yield, long duration, high pod-shattering, vulnerability to insect-pests and diseases. Dry seeds of the variety ''Bhat'' were treated with gamma rays (15, 20 and 25 k) with and without additional exposure to UV (2 hours at 260 nm). In M 2 , the frequency of viable mutations ranged from 0.42 to 5.64%. Both macro- and micro-mutations were identified in the M 2 and M 3 generations. Agronomically useful mutants were evaluated in replicated trials for three consecutive years. A mutant ''T 1 54'', resulting from 20kR + UV, surpassed the parent and local checks in yield. Besides, the mutant has other improved desirable attributes viz., yellow seed coat, early maturity (110 days) and tolerance to yellow mosaic and bacterial pustules. The mutant has retained the good seed viability and tolerance to stress conditions as observed in the parent. It is semi-determinate in nature and possesses white flowers in contrast to purple flowers found in the parent variety ''Bhat''. This mutant, later named ''NRC-1'', was entered in the multi-locational varietal trials under the All-India Co-ordinated Research Project on Soybean in 1988. It has faired well in three zones to enmerit its promotion for large scale evaluation in the northern plain zone, the central zone and the southern zone. It has yielded up to 3.64 t/ha at Parbhani in the Central Zone. (author)

  12. Dietary fiber and blood pressure control.

    Aleixandre, A; Miguel, M

    2016-04-01

    In the past few years, new strategies to control blood pressure levels are emerging by developing new bioactive components of foods. Fiber has been linked to the prevention of a number of cardiovascular diseases and disorders. β-Glucan, the main soluble fiber component in oat grains, was initially linked to a reduction in plasma cholesterol. Several studies have shown afterward that dietary fiber may also improve glycaemia, insulin resistance and weight loss. The effect of dietary fiber on arterial blood pressure has been the subject of far fewer studies than its effect on the above-mentioned variables, but research has already shown that fiber intake can decrease arterial blood pressure in hypertensive rats. Moreover, certain fibers can improve arterial blood pressure when administered to hypertensive and pre-hypertensive subjects. The present review summarizes all those studies which attempt to establish the antihypertensive effects of dietary fiber, as well as its effect on other cardiovascular risk factors.

    This report analyzes emerging evidence about the role of dietary advanced glycation end products (AGEs) as a cardiometabolic risk factor. Two important aspects are discussed: First, the modulation of AGE load by dietary AGEs; second, if the evidence of clinical and observational studies is enough to make dietary recommendations towards lowering AGE intake. Clinical studies in subjects with diabetes mellitus have shown that high intake of dietary AGEs increases inflammation markers, oxidative stress, and could impair endothelial function. In subjects at risk for cardiometabolic diseases (with overweight, obesity, or prediabetes), dietary AGE restriction decreases some inflammatory molecules and improves insulin sensitivity. However, studies in healthy subjects are limited, and not all of the studies have shown a decrease in circulating AGEs. Therefore, it is still unclear if dietary AGEs represent a health concern for people potentially at risk for cardiometabolic diseases. The evidence shows that dietary AGEs are bioavailable and absorbed, and the rate of excretion depends on dietary intake. The metabolic fate of most dietary AGEs remains unknown. Regardless, most studies have shown that by diminishing AGE intake, circulating levels will also decrease. Thus, dietary AGEs can modulate the AGE load at least in patients with DM, overweight, or obesity. Studies with specific clinical outcomes and large-scale observational studies are needed for a better risk assessment of dietary AGEs and to establish dietary recommendations accordingly.

    To examine associations between parenting styles, family structure and aspects of adolescent dietary behaviour. Cross-sectional study. Secondary schools in the East Midlands, UK. Adolescents aged 12-16 years (n 328, 57 % boys) completed an FFQ assessing their consumption of fruit, vegetables, unhealthy snacks and breakfast. Adolescents provided information on parental and sibling status and completed a seventeen-item instrument measuring the general parenting style dimensions of involvement and strictness, from which four styles were derived: indulgent, neglectful, authoritarian, authoritative. After controlling for adolescent gender and age, analysis of covariance revealed no significant interactions between parenting style and family structure variables for any of the dietary behaviours assessed. Significant main effects for family structure were observed only for breakfast consumption, with adolescents from dual-parent families (P parent families and those with one or more brother, respectively. Significant main effects for parenting style were observed for all dietary behaviours apart from vegetable consumption. Adolescents who described their parents as authoritative ate more fruit per day, fewer unhealthy snacks per day, and ate breakfast on more days per week than those who described their parents as neglectful. The positive associations between authoritative parenting style and adolescent dietary behaviour transcend family structure. Future research should be food-specific and assess the efficacy of strategies promoting the central attributes of an authoritative parenting style on the dietary behaviours of adolescents from a variety of family structures.

    It is legal tomarketmost naturally occurring substances as dietary supplements in the USA without manufacturers demonstrating they are safe or effective, and an endless variety of ingredients, from esoteric botanicals to unapproved pharmaceuticals, can be found in dietary supplements. Use of certain supplements can pose a risk, but since a robust reporting systemdoes not exist in the USA it is difficult to know which are problematic and the number of adverse events (AE) resulting from their use. Certain populations, includingmilitary personnel, aremore likely to use dietary supplements than the general population. Approximately 70% of military personnel take dietary supplements while about 50% of civilians do. Service members prefer supplements purported to enhance physical performance such as supposedly natural stimulants, protein and amino acids, and combination products. Since some of thesemay be problematic, Servicemembers are probably at higher risk of injury than the general population. Ten percent of military populations appear to be taking potentially risky supplements, and the US Department of Defense (DoD) has taken variousmeasures to protect uniformed personnel including education, policy changes, and restricting sales. Actions taken include launching Operation Supplement Safety (OPSS), introducing a High Risk Supplement list, educating health care professionals on reporting AE thatmight be associated with dietary supplements, recommending policy for reporting AE, and developing an online AE reporting system. OPSS is a DoD-wide effort to educate service members, leaders, health care providers, military families, and retirees on how to safely select supplements

    Food neophobia (FN) is described as the rejection to eat unknown foods. Because only little is known about the role of FN in adolescence the aim of this study was to examine potential determinants of FN and associations with dietary habits of DONALD study participants. FN was measured with Pliner's and Hobden's Food Neophobia Scale (FN Score (FNS): range 10-70) in 166 10-18-year-old adolescents. Participants' age, sex, body weight status and duration of breast-feeding as well as parents' FN and educational status were considered as determinants. Energy intake, distribution of macronutrients and two variety scores were calculated from 3-day weighed dietary records. Multivariable general linear models were performed for data analyses. Boys and girls did not differ in their FNS (median (Min-Max): boys 31 (10-58), girls 32 (14-59)). Increasing age (p = 0.010) and duration of total breast-feeding (p = 0.006) were associated with decreasing FNS in girls only. FN was further positively associated with parental FN in the total sample (p = 0.004). FN was negatively associated with protein intake in the total sample (p = 0.017). The overall low level of FN in the DONALD study can be ascribed to the low level of FN in adolescence in general. Congruently with other studies, age and breast-feeding duration were identified as determinants of girls' FN and parental FN was identified as determinant of FN in the total sample. Further, our results indicate that FN leads to reduced protein intakes. Dietary variety was not strongly affected, possibly because of a broad variety of food supply in Germany.

    To examine if children use supplements to fill gaps in nutritionally inadequate diets or whether supplements contribute to already adequate or excessive micronutrient intakes from foods. Data were analyzed for children (2-18 years) from the National Health and Nutrition Examination Survey 2003-2006, a nationally representative, cross-sectional survey (n = 7250). Diet was assessed using two 24-hour recalls, and dietary supplement use was assessed with a 30-day questionnaire. Prevalence of supplements use was 21% (vitamin D intakes were low for all children. Inadequate intakes of phosphorus, copper, selenium, folate, and vitamins B-6 and B-12 were minimal from foods alone among 2-8 year olds. However, among 9-18 year olds, a higher prevalence of inadequate intakes of magnesium, phosphorus, and vitamins A, C, and E were observed. Supplement use increased the likelihood of intakes above the upper tolerable intake level for iron, zinc, copper, selenium, folic acid, and vitamins A and C. Even with the use of supplements, more than a one-third of children failed to meet calcium and vitamin D recommendations. Children 2-8 years old had nutritionally adequate diets regardless of supplement use. However, in children older than 8 years, dietary supplements added micronutrients to diets that would have otherwise been inadequate for magnesium, phosphorus, vitamins A, C, and E. Supplement use contributed to the potential for excess intakes of some nutrients. These findings may have implications for reformulating dietary supplements for children. Published by Mosby, Inc.

    Supplement of dietary fibers (DF) is regarded as one of the most effective way to prevent and relieve chronic diseases caused by long-term intake of a high-fat diet in the current society. The health benefits of soluble dietary fibers (SDF) have been widely researched and applied, whereas the insoluble dietary fibers (IDF), which represent a higher proportion in plant food, were mistakenly thought to have effects only in fecal bulking. In this article, we proved the anti-obesity and glucose homeostasis improvement effects of IDF from pear pomace at first, and then the mechanisms responsible for these effects were analyzed. The preliminary study by real-time PCR and ELISA showed that this kind of IDF caused more changes in the gut microbiota compared with in satiety hormone or in hepatic metabolism. Further analysis of the gut microbiota by high-throughput amplicon sequencing showed IDF from pear pomace obviously improved the structure of the gut microbiota. Specifically, it promoted the growth of Bacteroidetes and inhibited the growth of Firmicutes. These results are coincident with previous hypothesis that the ratio of Bacteroidetes/Firmicutes is negatively related with obesity. In conclusion, our results demonstrated IDF from pear pomace could prevent high-fat diet-induced obesity in rats mainly by improving the structure of the gut microbiota.

    Muscular exercise promotes the production of radicals and other reactive oxygen species in the working muscle. Growing evidence indicates that reactive oxygen species are responsible for exercise-induced protein oxidation and contribute to muscle fatigue. To protect against exercise-induced oxidative injury, muscle cells contain complex endogenous cellular defence mechanisms (enzymatic and non-enzymatic antioxidants) to eliminate reactive oxygen species. Furthermore, exogenous dietary antioxidants interact with endogenous antioxidants to form a cooperative network of cellular antioxidants. Knowledge that exercise-induced oxidant formation can contribute to muscle fatigue has resulted in numerous investigations examining the effects of antioxidant supplementation on human exercise performance. To date, there is limited evidence that dietary supplementation with antioxidants will improve human performance. Furthermore, it is currently unclear whether regular vigorous exercise increases the need for dietary intake of antioxidants. Clearly, additional research that analyses the antioxidant requirements of individual athletes is needed.

    For nutrition practitioners and researchers, assessing dietary intake of children and adults with a high level of accuracy continues to be a challenge. Developments in mobile technologies have created a role for images in the assessment of dietary intake. The objective of this review was to examine peer-reviewed published papers covering development, evaluation and/or validation of image-assisted or image-based dietary assessment methods from December 2013 to January 2016. Images taken with handheld devices or wearable cameras have been used to assist traditional dietary assessment methods for portion size estimations made by dietitians (image-assisted methods). Image-assisted approaches can supplement either dietary records or 24-h dietary recalls. In recent years, image-based approaches integrating application technology for mobile devices have been developed (image-based methods). Image-based approaches aim at capturing all eating occasions by images as the primary record of dietary intake, and therefore follow the methodology of food records. The present paper reviews several image-assisted and image-based methods, their benefits and challenges; followed by details on an image-based mobile food record. Mobile technology offers a wide range of feasible options for dietary assessment, which are easier to incorporate into daily routines. The presented studies illustrate that image-assisted methods can improve the accuracy of conventional dietary assessment methods by adding eating occasion detail via pictures captured by an individual (dynamic images). All of the studies reduced underreporting with the help of images compared with results with traditional assessment methods. Studies with larger sample sizes are needed to better delineate attributes with regards to age of user, degree of error and cost.

    Previous study showed that dietary Bacillus licheniformis (B. licheniformis) administration contributes to the improvement of laying performance and egg quality in laying hens. In this study, we aimed to further evaluate its underlying mechanisms. Three hundred sixty Hy-Line Variety W-36 hens (28 weeks of age) were randomized into four groups, each group with six replications (n = 15). The control group received the basal diet and the treatment groups received the same basal diets supplemented with 0.01, 0.03, and 0.06% B. licheniformis powder (2 × 10 10  cfu/g) for an 8-week trial. The results demonstrate that B. licheniformis significantly enhance the intestinal barrier functions via decreasing gut permeability, promoting mucin-2 transcription, and regulating inflammatory cytokines. The systemic immunity of layers in B. licheniformis treatment groups is improved through modulating the specific and non-specific immunity. In addition, gene expressions of hormone receptors, including estrogen receptor α, estrogen receptor β, and follicle-stimulating hormone receptor, are also regulated by B. licheniformis. Meanwhile, compared with the control, B. licheniformis significantly increase gonadotropin-releasing hormone level, but markedly reduce ghrelin and inhibin secretions. Overall, our data suggest that dietary inclusion of B. licheniformis can improve the intestinal barrier function and systemic immunity and regulate reproductive hormone secretions, which contribute to better laying performance and egg quality of hens.

    Full Text Available The health of children in Ghana has improved in recent years. However, the current prevalence rates of malnutrition remain above internationally acceptable levels. This study, therefore, revisits the determinants of child health by using Ghana’s Multiple Indicator Cluster Survey to investigate the effect of infant feeding practices on child health. We used the World Health Organization’s Infant and Young Children Feeding guidelines to measure dietary quality. The econometric analyses show that dietary diversity may cause improvement in children’s health in Ghana. This suggests that educational campaigns on proper infant feeding and complementary dieting could be an effective means of improving the health of children in Ghana.

    This study aimed to concentrate dietary fiber (DF) from peach (Prunus persica) juice by-product (PJBP), to improve its functional properties, and its polyphenols bioavailability. The dietary fiber concentrates (DFCs) were obtained from PJBP using water/ethanol treatments (100:0, 20:80, 50:50, 80:20, and 0:100, v/v) at 1:5 ratio (wet weight/solvent, w/v) for 5 and 20 min at 21 °C. All treatments concentrated condensed tannins, total and insoluble DF, with the highest content found with 100% H 2 O treatment. The major polyphenols of DFC were 4-O-caffeoylquinic, chlorogenic, and 1,5-di-O-caffeoylquinic acids. Water and oil retention capacity and maximum glucose diffusion rate were improved mainly with 100% H 2 O treatment. Healthy rats were fed with a standard diet supplemented with 8% of PJBP, DFC obtained with 100% H 2 O for 5 min, or DFC obtained with 20% EtOH for 5 min. Gastrointestinal digesta weight and viscosity were increased in animals supplemented with 100% H 2 O DFC. Moreover, the urinary excretion of polyphenol metabolites, mainly glucuronide and sulfate conjugates, was increased with this treatment, indicating a greater bioavailability of PJBP polyphenols, which was associated with an increased dietary fiber porosity. Water treatment could be used to potentiate PJBP functional properties and polyphenols bioavailability. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

    Dietary modification, through supplementation and elimination diets, has become an area of interest to help slow skin aging, reduce symptom severity or prevent reoccurrence of certain dermatologic conditions [Clinical Dermatology vol. 31 (2013) 677-700]. Free radical components (reactive oxygen species or ROS) or lipid peroxide (LPO) is involved in the pathogenesis and progression of accelerated skin aging when prolonged oxidative stress occurs. The use of antioxidant-related therapies such as nutraceuticals is of particular interest in restoring skin homeostasis. Antioxidant carotenoid zeaxanthin is concentrated in the eye and skin tissue and believed to decrease the formation of ROS associated with UV light exposure. With zeaxanthin, phytoceramides, and botanical extracts an oral and topical test product (with zeaxanthin, algae extracts, peptides, hyaluronate) have been developed to improve the appearance and condition of skin when used as directed. Subjects were divided into three groups: two tests (skin formula 1 - oral product alone (ZO-1), skin formula 2- oral product with topical product (ZO-2 + ZT)), and one placebo control. The study consisted of a washout visit, baseline (randomization), week two (2), week four (4), week six (6), week eight (8), and week twelve (12). Key parameters measured were as follows: fine lines, deep lines, total wrinkles, wrinkle severity, radiance/skin color (L, a*, b*), discolorations, and skin pigment homogeneity. Thirty-one subjects completed the twelve-week study; no adverse events were recorded during the study. Statistically significant improvements from baseline mean hydration score were observed in active groups at weeks 2, 6, and 8. A statistically significant difference was observed between mean differences from baseline scores for total wrinkle count at week 4 for the combination active groups compared to placebo. A statistically significant difference from baseline scores for fine lines count was also observed at

    An increasing number of low-income countries (LICs) exhibit high rates of malnutrition coincident with rising rates of overweight and obesity. Individual-level dietary data are needed to inform effective responses, yet dietary data from large-scale surveys conducted in LICs remain extremely limited. This discussion paper first seeks to highlight the barriers to collection and use of individual-level dietary data in LICs. Second, it introduces readers to new technological developments and research initiatives to remedy this situation, led by the International Dietary Data Expansion (INDDEX) Project. Constraints to conducting large-scale dietary assessments include significant costs, time burden, technical complexity, and limited investment in dietary research infrastructure, including the necessary tools and databases required to collect individual-level dietary data in large surveys. To address existing bottlenecks, the INDDEX Project is developing a dietary assessment platform for LICs, called INDDEX24, consisting of a mobile application integrated with a web database application, which is expected to facilitate seamless data collection and processing. These tools will be subject to rigorous testing including feasibility, validation, and cost studies. To scale up dietary data collection and use in LICs, the INDDEX Project will also invest in food composition databases, an individual-level dietary data dissemination platform, and capacity development activities. Although the INDDEX Project activities are expected to improve the ability of researchers and policymakers in low-income countries to collect, process, and use dietary data, the global nutrition community is urged to commit further significant investments in order to adequately address the range and scope of challenges described in this paper.

    Full Text Available Dietary components of adolescent obesity interventions are rarely evaluated with comprehensive reporting of dietary change. The objective was to assess dietary change in overweight adolescents, including adherence to dietary intervention. The dietary intervention was part of a multi-component intervention (CAFAP targeting the physical activity, sedentary and healthy eating behaviors of overweight adolescents (n = 69. CAFAP was a staggered entry, within-subject, waitlist controlled clinical trial with 12 months of follow up. Diet was assessed using three-day food records and a brief eating behavior questionnaire. Changes in dietary outcomes were assessed using linear mixed models, adjusted for underreporting. Food record data suggested reduced adherence to dietary intervention messages over time following the intervention, despite conflicting information from the brief eating behavior questionnaire. During the intervention, energy intake was stable but favorable nutrient changes occurred. During the 12 month maintenance period; self-reported eating behaviors improved, energy intake remained stable but dietary fat and saturated fat intake gradually returned to baseline levels. Discrepancies between outcomes from brief dietary assessment methods and three-day food records show differences between perceived and actual intake, highlighting the need for detailed dietary reporting. Further, adherence to dietary intervention principles reduces over time, indicating a need for better maintenance support.

    To assess the effect of dietary patterns on all deaths and diabetes-related deaths in the Japanese Elderly Diabetes Intervention Trial (J-EDIT). We investigated relationships between that of overall mortality and dietary pattern, and diabetes-related deaths and dietary pattern as observed among 912 registered cases of the J-EDIT study, which is a prospective follow-up study of elderly Japanese type 2 diabetic patients. Factor analysis with the factor number 3 led to deriving three dietary patterns (healthy type, snack type and greasy type). The relationship between these patterns and overall mortality or diabetes-related death was investigated. Although not statistically significant, there was a lower tendency of overall mortality and diabetes-related deaths for the healthy type dietary pattern. When the tendencies of overall mortality were analyzed for "young-old," who are younger than 75 years-of age, and "old-old" of over 75 years-of-age, the mortality rate for the greasy type and healthy type dietary patterns were nearly the same and higher than the snack type dietary pattern in young-old. In contrast, in old-old, a higher mortality rate was reported for the greasy type dietary pattern and a lower mortality rate was reported for the healthy type dietary pattern. The hazard ratio by Cox regression analysis for greasy type to healthy type in old-old was 3.03 (P = 0.04, CI 1.07-8.57). Furthermore, in old-old, as vegetable consumption increased, the lower the tendency foroverall mortality, and the more fish that was consumed, the overall mortality significantly decreased (P = 0.020) in the tertile. The greasy type dietary pattern with an increased amount of sugar, fat and meat led to poor life prognosis for elderly Japanese type 2 diabetic patients. The healthy type dietary pattern rich in vegetable and fish, which is similar to the Mediterranean diet and Dietary Approach to Stop Hypertension diet, was suggested to improve life prognosis. © 2012 Japan Geriatrics

  11. Improved method for measurement of dietary fiber as non-starch polysaccharides in plant foods.

    Englyst, H N; Cummings, J H

    1988-01-01

    A method is described that allows rapid estimation of total, soluble, and insoluble dietary fiber as the non-starch polysaccharides (NSP) in plant foods. It is a modification of an earlier, more complex procedure. Starch is completely removed enzymatically, and NSP is measured as the sum of its constituent sugars released by acid hydrolysis. The sugars may, in turn, be measured by gas chromatography (GC), giving values for individual monosaccharides, or more rapidly by colorimetry. Both GC and colorimetry are suitable for routine measurement of total, soluble, and insoluble dietary fiber in cereals, fruits, and vegetables. Values obtained are not affected by food processing so the dietary fiber content of various processed foods and mixed diets can be calculated simply from knowing the amount in the raw materials. The additional information obtained by GC analysis is valuable in the interpretation of physiological studies and in epidemiology where disease is related to type and amount of dietary fiber.

    Full Text Available Background: WHO statistics show that Indonesia has the fourth highest number of diabetes sufferers. The International Diabetes Federation‟s 5th estimated that in 2011 there were 71.4 million people in South East Asia region were suffering with DM Purpose: To develop a family-based dietary self-management support program to improve dietary behaviors in patients with T2DM. Method: A literature review was conducted by reviewing articles related evidence-based practices. Only articles in the English and Indonesian languages were reviewed. The search found eleven published experimental studies related to the topic. Result: Even though dietary self-management has benefits for patients with diabetes, many studies have found that these patients often have difficulty in establishing or maintaining an effective program to self-manage their dietary behaviors. Lack of family support is one factor that often seems to be related to such failures. Family participation in a diabetes education program also had positive psychosocial impacts. Otherwise, another study found that family might not always have a positive impact on self-management. Therefore, this review recommends that development of a family-based support program could be a positive factor in helping to improve dietary self-management behaviors in patients with T2DM. Self-management theory by Funnell and Anderson‟s work (2004 can guide the development of a program with the goal of empowering individuals and families in improving the patient‟s dietary behaviors. The program consists of: (1 reflecting on current and/or past self-management experiences by listening to the patient about their dietary behaviors, (2 discussing the emotions and feelings of the patients, (3 engaging the patient in improving their situation by active listening and helping the patient reflect on their problems and identifying effective strategies, (4 providing information about dietary management and problem

    Objective To examine if children use supplements to fill gaps in nutritionally inadequate diets or whether supplements contribute to already adequate or excessive micronutrient intakes from foods. Study design Data were analyzed for children (2–18 y) from the NHANES 2003–2006, a nationally representative, cross-sectional survey (n=7,250). Diet was assessed using two 24-hour recalls, and dietary supplement use was assessed with a 30-day questionnaire. Results Prevalence of supplements use was 21% (Supplement users had higher micronutrient intakes than nonusers. Calcium and vitamin D intakes were low for all children. Inadequate intakes of phosphorus, copper, selenium, folate, and vitamins B-6 and B-12 were minimal from foods alone among 2–8 y olds. However, among 9–18 y olds, a higher prevalence of inadequate intakes of magnesium, phosphorus, and vitamins A, C, and E were observed. Supplement use increased the likelihood of intakes above the Upper Tolerable Intake Level for iron, zinc, copper, selenium, folic acid, and vitamins A and C. Conclusions Even with the use of supplements, more than a one-third of children failed to meet calcium and vitamin D recommendations. Children 2–8 y had nutritionally adequate diets regardless of supplement use. However, in children older than 8 y dietary supplements added micronutrients to diets that would have otherwise been inadequate for magnesium, phosphorus, vitamins A,C, and E. Supplement use contributed to the potential for excess intakes of some nutrients. These findings may have implications for reformulating dietary supplements for children. PMID:22717218

    2018-03-01

    Some dietary supplements are recommended to athletes based on data that supports improved exercise performance. Other dietary supplements are not ergogenic per se, but may improve health, adaptation to exercise, or recovery from injury, and so could help athletes to train and/or compete more effectively. In this review, we describe several dietary supplements that may improve health, exercise adaptation, or recovery. Creatine monohydrate may improve recovery from and adaptation to intense training, recovery from periods of injury with extreme inactivity, cognitive processing, and reduce severity of or enhance recovery from mild traumatic brain injury (mTBI). Omega 3-fatty acid supplementation may also reduce severity of or enhance recovery from mTBI. Replenishment of vitamin D insufficiency or deficiency will likely improve some aspects of immune, bone, and muscle health. Probiotic supplementation can reduce the incidence, duration, and severity of upper respiratory tract infection, which may indirectly improve training or competitive performance. Preliminary data show that gelatin and/or collagen may improve connective tissue health. Some anti-inflammatory supplements, such as curcumin or tart cherry juice, may reduce inflammation and possibly delayed onset muscle soreness (DOMS). Beta-hydroxy beta-methylbutyrate (HMB) does not consistently increase strength and/or lean mass or reduce markers of muscle damage, but more research on recovery from injury that includes periods of extreme inactivity is needed. Several dietary supplements, including creatine monohydrate, omega 3-fatty acids, vitamin D, probiotics, gelatin, and curcumin/tart cherry juice could help athletes train and/or compete more effectively.

    Hellen Clair Garcez NABUCO

    Full Text Available ABSTRACT Objective: To investigate the prevalence and establish the profile of the consumption of dietary supplements among Brazilian athletes. Methods: A total of 182 athletes of both genders from 20 different sports participated in this study. The athletes answered a questionnaire containing sociodemographic and sports-related questions and were interviewed about the consumption of dietary supplements. Results: Forty seven percent of athletes reported having consumed at least one type of dietary supplement and 38% said they use more than three different types of supplements concurrently. Whey protein was the most commonly consumed supplement, and the most frequently mentioned reason for its consumption was performance improvement. The main source of information was coaches, and individual sport athletes were the greatest consumers and the most likely to seek dietary supplement. Conclusion: Approximately half of the participants used dietary supplements, which on most occasions were recommended by coaches. The consumption profile also revealed multiple supplementation practice and showed that nutrition education is essential for this specific population.

    Background: Above-average dietary protein, as a single nutrient, improves musculoskeletal health. Evaluating the link between dietary protein and musculoskeletal health from a whole-diet perspective is important, as dietary guidelines focus on dietary patterns. Objective: We examined the prospective association of novel dietary protein food clusters (derived from established dietary pattern techniques) with appendicular lean mass (ALM), quadriceps strength (QS), and bone mineral density (BMD) in 2986 men and women, aged 19-72 y, from the Framingham Third Generation Study. Design: Total protein intake was estimated by food-frequency questionnaire in 2002-2005. A cluster analysis was used to classify participants into mutually exclusive groups, which were determined by using the percentage of contribution of food intake to overall protein intake. General linear modeling was used to 1 ) estimate the association between protein intake (grams per day) and BMD, ALM, appendicular lean mass normalized for height (ALM/ht 2 ), and QS (2008-2011) and to 2 ) calculate adjusted least-squares mean outcomes across quartiles of protein (grams per day) and protein food clusters. Results: The mean ± SD age of subjects was 40 ± 9 y; 82% of participants met the Recommended Daily Allowance (0.8 g · kg body weight -1 · d -1 ). The following 6 dietary protein food clusters were identified: fast food and full-fat dairy, fish, red meat, chicken, low-fat milk, and legumes. BMD was not different across quartiles of protein intake ( P -trend range = 0.32-0.82); but significant positive trends were observed for ALM, ALM/ht 2 ( P dietary protein is associated with ALM and QS but not with BMD. In this study, dietary protein food patterns do not provide further insight into beneficial protein effects on muscle outcomes. © 2017 American Society for Nutrition.

    Objective The purpose of this study was to examine the nutritional adequacy and dietary composition among women residing in Zinder and Maradi of Niger, and the factors that affect the variety of their dietary intake. Methods Data from 3360 women of ages 15-49 were used in the analysis. The variable of interest was the Women Dietary Diversity Score (WDDS), which is the simple sum of scores of the 9 categorized food groups, ranging from 0 to 9. Lower values for WDDS indicate nutritionally inadequate dietary diversity. Analysis included descriptive, Mann-Whitney U test and linear regression. Results The majority of the participants were residing in the Maradi Region (56.7%) and were living in households with both male and female adults (94.9%). The mean WDDS was 3.5 in Zinder compared to 2.5 in Maradi (p Hunger Scale (HHS) had a negative and significant effect on WDDS. Conclusion Niger has one of the highest concentrations of malnutrition in the world. In 2012, approximately 2.5 million Nigeriens were affected by malnutrition. Our study results reinforce the importance to conduct more studies that examine the nutritional intake of women in Niger.

    2013-01-01

    Full Text Available Aim. To investigate the role of AMPK activation and autophagy in mediating the beneficial effects of exercise and caloric restriction in obesity. Methods. Dietary-induced obesity mice were made and divided into 5 groups; one additional group of normal mice serves as control. Mice in each group received different combinations of interventions including low fat diet, caloric restriction, and exercise. Then their metabolic conditions were assessed by measuring serum glucose and insulin, serum lipids, and liver function. AMPK phosphorylation and autophagy activity were detected by western blotting. Results. Obese mice models were successfully induced by high fat diet. Caloric restriction consistently improved the metabolic conditions of the obese mice, and the effects are more prominent than the mice that received only exercise. Also, caloric restriction, exercise, and low fat diet showed a synergistic effect in the improvement of metabolic conditions. Western blotting results showed that this improvement was not related with the activation of AMPK in liver, skeletal muscle, or heart but correlates well with the autophagy activity. Conclusion. Caloric restriction has more prominent beneficial effects than exercise in dietary-induced obese mice. These effects are correlated with the autophagy activity and may be independent of AMPK activation.

    To assess the impact on food-related cost of meals to fulfill the new compulsory dietary standards for primary schools in France. A descriptive study assessed the relationship between the level of compliance with the standards of observed school meals and their food-related cost. An analytical study assessed the cost of series of meals published in professional journals, and complying or not with new dietary standards. The costs were based on prices actually paid for food used to prepare school meals. Food-related cost of meals. Parametric and nonparametric tests from a total of 42 and 120 series of 20 meals in the analytical and descriptive studies, respectively. The descriptive study indicated that meeting the standards was not related to cost. The analytical study showed that fulfilling the frequency guidelines increased the cost, whereas fulfilling the portion sizes criteria decreased it. Series of meals fully respecting the standards (ie, frequency and portion sizes) cost significantly less (-0.10 €/meal) than series not fulfilling them, because the standards recommend smaller portion sizes. Introducing portion sizes rules in dietary standards for school catering may help increase dietary quality without increasing the food cost of meals.

    Providing a variety of foods has been emphasized as one of the most important features of optimal complementary feeding. This study investigated key beliefs that guide mothers' intention to adherence to dietary diversity in their 1-2-year-old children's complementary feeding. This was a cross-sectional study involving 290 mothers (mean age = 27, standard deviation = 5.32) with child 1-2-year-old attending maternal and child health section of health centers in Rasht, Iran. To represent the socioeconomic status of the participants, 6 centers out of 15 were selected from three different socioeconomic areas (low-, middle-, and high-income areas). Mothers completed a questionnaire assessing intention and belief-based items of theory of planned behavior. Correlations and multiple regression analyses were performed. The mean age of mothers was 27 ± 5.33 (27-43 years). Regression analyses revealed that among behavioral beliefs, the perception that adherence to dietary diversity would lead to improve children's growth was the significant predictor of intention (β = 0.13, P = 0.04). Regarding normative beliefs, perceived social pressure from health-care professionals to adherence to dietary diversity significantly predicted intention (β = 0.15, P = 0.01). Among control beliefs, the perception that daily pressures made difficult adherence to dietary diversity was the key determinant (β = 0.19, P = 0.01). Findings of this study represent the important beliefs that can be addressed in development planning aimed at modifying mothers' child complementary feeding practices.

    Full Text Available The prevalence of adverse mental health outcomes in adults is increasing. Although beneficial effects of selected micronutrients and foods on mental health have been reported, they do not reflect the impact of the habitual diet on mental health. Therefore, our objective is to examine potential associations between dietary quality, dietary composition and compliance with food pyramid recommendations with depressive symptoms, anxiety and well-being (assessed using CES-D, HADS-A and WHO-5 screening tools in a cross-sectional sample of 2047 middle-aged adults. Diet was assessed using a self-completed FFQ. Chi-square tests, t-tests and logistic regression analyses were used to investigate the associations between dietary components and mental health outcomes. Dietary quality, but not dietary composition or guideline adherence, was associated with well-being. Those with high dietary quality were more likely to report well-being (OR =1.67, 95% CI 1.15–2.44, p = 0.007 relative to those with low dietary quality. This remained significant among females (OR = 1.92, (95% CI 1.14–3.23, p = 0.014 and non-obese individuals (OR = 2.03, 95% CI 1.28–3.20, p = 0.003. No associations between any dietary measures with anxiety or depressive symptoms were observed. These novel results highlight the importance of dietary quality in maintaining optimal psychological well-being. Better understanding of the relationship between dietary quality and mental health may provide insight into potential therapeutic or intervention strategies to improve mental health and well-being.

    Full Text Available Abstract Dietary Guidelines for Americans provide nutrition advice aimed at promoting healthy dietary choices for life-long health and reducing risk of chronic diseases. With the advancing age of the population, the 2010 Dietary Guidelines confront increasing risks for age-related problems of obesity, osteoporosis, type 2 diabetes, Metabolic Syndrome, heart disease, and sarcopenia. New research demonstrates that the meal distribution and amount of protein are important in maintaining body composition, bone health and glucose homeostasis. This editorial reviews the benefits of dietary protein for adult health, addresses omissions in current nutrition guidelines, and offers concepts for improving the Dietary Guidelines.

    The food prices including pulses were beginning to increase from 2008, something that was not expected to happen before 2020. It was due to climate change, a scarcity of good arable land, water and nutrients. With these obstacles, we must produce almost double than what we are producing now to achieve food security by 2050. It can be achieved through crop improvement. Crop improvement is the art and science of changing the genetic make of crop plant in desire direction through various method of plant breeding. Mutation breeding is one of the techniques which utilize the physical and chemical mutagens to create genetic variability. Till date more than 3200 mutant varieties have been developed worldwide in which two physical mutagens i.e. X-rays and gamma rays have major contributions. Bhabha Atomic Research Centre is one of the leading institutes in India where nuclear energy is used for crop improvement, which resulted in to development of 43 improved high yielding varieties in different crops including 19 varieties of pulse crops. These varieties are contributing significantly to production of pulses and ultimately to national food security. (author)

    Full Text Available The multiple-pass 24-h dietary recall is used in most national dietary surveys. Our purpose was to assess if adolescents’ accuracy of recall improved when a 5-step multiple-pass 24-h recall was repeated. Participants (n = 24, were Chinese-American youths aged between 11 and 15 years and lived in a supervised environment as part of a metabolic feeding study. The 24-h recalls were conducted on two occasions during the first five days of the study. The four steps (quick list; forgotten foods; time and eating occasion; detailed description of the food/beverage of the 24-h recall were assessed for matches by category. Differences were observed in the matching for the time and occasion step (p < 0.01, detailed description (p < 0.05 and portion size matching (p < 0.05. Omission rates were higher for the second recall (p < 0.05 quick list; p < 0.01 forgotten foods. The adolescents over-estimated energy intake on the first (11.3% ± 22.5%; p < 0.05 and second recall (10.1% ± 20.8% compared with the known food and beverage items. These results suggest that the adolescents’ accuracy to recall food items declined with a second 24-h recall when repeated over two non-consecutive days.

    The variation of glucosinolates and quinone reductase (QR) activity in fourteen varieties of Chinese kale (Brassica oleracea var. alboglabra Bailey) was investigated in the present study. Results showed that gluconapin (GNA), instead of glucoraphanin (GRA), was the most predominant glucosinolate in all varieties, and QR activity was remarkably positively correlated with the glucoraphanin level. AOP2, a tandem 2-oxoglutarate-dependent dioxygenase, catalyzes the conversion of glucoraphanin to gluconapin in glucosinolate biosynthesis. Here, antisense AOP2 was transformed into Gailan-04, the variety with the highest gluconapin content and ratio of GNA/GRA. The glucoraphanin content and corresponding QR activity were notably increased in transgenic plants, while no significant difference at the level of other main nutritional compounds (total phenolics, vitamin C, carotenoids and chlorophyll) was observed between the transgenic lines and the wide-type plants. Taken together, metabolic engineering is a good practice for improvement of glucoraphanin in Chinese kale. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Nine types of commercially produced variety breads, plain bagels, corn tortillas, and three types of pasta products were obtained from each of four cities, New York, San Francisco, Atlanta, and Kansas City. Proximate components and 12 minerals and vitamins were determined in these and in cooked pasta products. Available carbohydrate and energy values were calculated. On the average, French, Italian, and pita breads were lower in moisture than other breads. Protein in bread products averaged between 7.6% and 10.4% and in cooked pastas and tortillas between 4.4% and 5.3%. Bagels averaged 10.2% protein. Insoluble dietary fiber in whole wheat bread averaged 5.6%; for most products, dietary fiber values were five- to eightfold higher than crude fiber values. Pasta products and tortillas were virtually free of sodium. Sodium in bread products averaged between 379 and 689 mg/100 gm. Although all pasta products and most bread products were enriched, calcium was often not included. Iron averaged from 2.16 to 3.29 mg/100 gm in bread products and 3.10 to 4.24 mg/100 gm in dry pasta products. Products made with unrefined or less-refined flours and/or containing germ and bran tended to be high in phosphorus, magnesium, zinc, and manganese, and, to a lesser extent, in copper. A good portion of potassium, thiamin, riboflavin, and niacin in pasta products was lost during cooking.

    Migration has an influence on health behavior and food intake. Dietary variety is a key component to high-quality diets because a single food item does not contain a variety of nutrients and may not reflect nutritional adequacy. We aimed to compare the dietary diversity scores (DDS), food variety scores (FVS), and nutrient adequacy levels of married Filipino immigrant women in Korea to those of Korean women. We matched the data of 474 participants aged 20-57 years from the Filipino Women's Diet and Health Study (FiLWHEL) by age category with those of married Korean women randomly selected from the Korea National Health and Nutrition Examination Survey (KNHANES). Dietary information in FiLWHEL and KNHANES were assessed through the 24-hour recall method. We calculated the DDS by summing the number of eleven food groups consumed (DDS 10 g if they consumed at least 10 g/day; DDS all if they consumed any amount) and the FVS by counting the number of food items consumed. For nutrient adequacy, we calculated the probability of adequacy (PA) and intake below the estimated average requirement (EAR). Filipino women had a lower DDS and FVS in comparison to Korean women. The means (±SDs) of DDS 10 g, DDS all, and FVS for Filipino women versus Korean women were 6.0 (±1.6) versus 6.8 (±1.5) (p Filipino women than for Korean women. The mean probability of adequacy (MPA) of nutrient intake of the nine selected nutrients was lower for Filipino women in comparison to Korean women. The mean (±SD) was 0.55 (±0.28) versus 0.66 (±0.26), respectively. Our findings showed that married Filipino immigrant women in Korea had lower dietary variety scores in comparison to Korean women. This was reflected in their nutritional adequacy. Nutrition education focusing on the promotion of eating a variety of foods may be needed for Filipino immigrant women in Korea.

    Social relationships are an important aspect of a person's social environment that can protect against a wide range of chronic conditions and facilitate recovery from disease. Social relationships have also been linked to dietary behaviour which may be an important pathway through which social circumstances exert their influence on health. Yet, questions remain about which structural aspects of social relationships most affect healthful dietary behaviours and whether different structural components interact to produce a combined effect. Using data from adults (≥50 years) in the European Prospective Investigation of Cancer-Norfolk study (1996-2002), we examined marital status, living arrangement and social isolation in relation to scores for variety of fruit and vegetable intake as a marker of diet quality associated with adverse health outcomes. Data were analysed with multivariable linear regression models for gender-specific and interaction associations. We found that being single or widowed was associated with a lower variety score, particularly vegetable variety, and associations were enhanced when combined with male gender, living alone or infrequent friend contact. Lower variety scores for lone-living were also observed, especially for men. Infrequent friend contact interacted with living arrangement to amplify negative associations of lone-living with variety, with statistically significant differences in contact frequency for vegetable variety. Lower levels of friend contact were associated with reduced variety of fruits and vegetables in a graded trend for both genders; the trend was more pronounced among men. Family contact appeared to have limited association with vegetable variety in men; among women, weekly contact was significantly and positively associated with vegetable variety compared to daily family contact. Results highlight the importance of considering living arrangement and/or frequency of social contact when assessing whether widowed

    2015-11-01

    It is the position of the Academy of Nutrition and Dietetics that the public should consume adequate amounts of dietary fiber from a variety of plant foods. Dietary fiber is defined by the Institute of Medicine Food Nutrition Board as "nondigestible carbohydrates and lignin that are intrinsic and intact in plants." Populations that consume more dietary fiber have less chronic disease. Higher intakes of dietary fiber reduce the risk of developing several chronic diseases, including cardiovascular disease, type 2 diabetes, and some cancers, and have been associated with lower body weights. The Adequate Intake for fiber is 14 g total fiber per 1,000 kcal, or 25 g for adult women and 38 g for adult men, based on research demonstrating protection against coronary heart disease. Properties of dietary fiber, such as fermentability and viscosity, are thought to be important parameters influencing the risk of disease. Plant components associated with dietary fiber may also contribute to reduced disease risk. The mean intake of dietary fiber in the United States is 17 g/day with only 5% of the population meeting the Adequate Intake. Healthy adults and children can achieve adequate dietary fiber intakes by increasing their intake of plant foods while concurrently decreasing energy from foods high in added sugar and fat, and low in fiber. Dietary messages to increase consumption of whole grains, legumes, vegetables, fruits, and nuts should be broadly supported by food and nutrition practitioners.

    To identify the dietary patterns of adult men and examine their relationships with nutrient intake and chronic disease risk over long-term follow-up. Baseline 145-item food frequency questionnaires from 1,666 Framingham Offspring-Spouse cohort men were used to identify comprehensive dietary patterns. Independent 3-day dietary records at baseline and 8 years later provided estimates of subjects' nutrient intake by dietary pattern. Chronic disease risk factor status was compared at baseline and 16-year follow-up across all male dietary patterns. Cluster analysis was applied to food frequency data to identify non-overlapping male dietary patterns. Analysis of covariance and logistic regression were used to compare nutrient intake, summary nutritional risk scores, and chronic disease risk status at baseline and follow-up by male dietary pattern. Five distinct and comprehensive dietary patterns of Framingham Offspring-Spouse men were identified and ordered according to overall nutritional risk: Transition to Heart Healthy, Higher Starch, Average Male, Lower Variety, and Empty Calories. Nutritional risk was high and varied by dietary pattern; key nutrient contrasts were stable over 8-year follow-up. Chronic disease risk also varied by dietary pattern and specific subgroup differences persisted over 16 years, notably rates of overweight/obesity and smoking. Quantitative cluster analysis applied to food frequency questionnaire data identified five distinct, comprehensive, and stable dietary patterns of adult Framingham Offspring-Spouse cohort men. The close associations between the dietary patterns, nutritional risk, and chronic disease profiles of men emphasize the importance of targeted preventive nutrition interventions to promote health in the male population.

    Five elite varieties of barnyard (Echinochloa frumentacea) and finger (Eleusine coracana) growing at northwestern Himalaya were investigated for nutraceutical and antinutritional properties. Barnyard millet contained higher amount of crude fiber, total dietary fiber, tryptophan content, total carotenoids, α-tocopherol compared to the finger millet whereas the finger millet contains higher amount of methionine and ascorbic acid as compared to the barnyard millet. The secondary metabolites of biological functions were analyzed and found that barnyard millet contained the higher amount of polyphenols, tannins and ortho-dihydroxy phenol content compared to finger millet. Among antinutitional compounds barnyard millet contained lower phytic acid content compare to finger millet whereas no significant difference in trypsin inhibition activity of barnyard millet and finger millet varieties were found. Barnyard millet contained higher acid phosphatase, α-galactosidase and α-amylase inhibitor activity compared to finger millet. Finger millet seeds contained about 10-13 folds higher calcium content and double amount of manganese content in comparison to barnyard millet seeds. Present study suggests that barnyard millet varieties studied under present investigation were found nutritionally superior compared to finger millet varieties.

    The present study was carried out to investigate the effect of dietary supplementation of organic selenium (Se) on performance, egg quality indices, and yolk oxidative stability in laying hens fed diets with different fat sources. A total of 270 Hy-line W-36 Leghorn hens of 47 weeks of age were randomly distributed into the 5 replicate cages of 9 dietary treatments. Experimental diets consisted of a 3 × 3 factorial arrangement of treatments with three different fat sources (soybean oil, SO; yellow grease, YG; and palm fat powder, PFP) and three different levels of supplemental Se (0, 0.2, and 0.4 mg/kg of diet) as supplied by zinc-L-selenomethionine (ZnSeMet) complex, which fed during a 77-day feeding trial including 7 days for adaptation and 70 days as the main recording period. Results showed that the highest (P hens fed on SO-supplemented diets. Hen-day egg production was affected by both dietary fat source (P feed intake was not affected by experimental diets during the first 35-day period, dietary inclusion of PFP reduced feed intake during both second 35-day (P feed conversion ratio during the first 35-day period was assigned to the birds fed on SO-diets, followed by those fed YG-diets. Dietary supplementation of ZnSeMet improved (P feed efficiency during the first 35-day period. Supplementation of ZnSeMet into the diets increased yolk index, with more impact in hens fed on YG-diets. The highest concentration of yolk malondialdehyde was observed in YG-fed groups, and ZnSeMet supplementation of diets decreased (P hens fed on diets supplemented by YG, followed by those on SO-diets. Although different fat sources had no effect on antibody titer against Newcastle disease virus, supplemental ZnSeMet improved (P hens, with the highest impact in diets containing oxidized (high peroxide values) fat sources.

    The current study aimed to assess Uruguayan consumers' accounts of their own need to change their dietary patterns, their intended changes and the barriers related to doing so, and to compare the intentions and barriers with the recommendations of the national dietary guidelines. An online survey with 2381 Uruguayan employed adults, aged between 18 and 65 years, 65 % females, was conducted. Participants had to answer two open-ended questions related to changes they could make in the foods they eat and/or the way in which they eat to improve the quality of their diet and the reasons why they had not implemented those changes yet. Content analysis using inductive coding by two researchers was used to analyse the responses. Consumers mainly intended to change consumption of types of foods, particularly eating more fruits, vegetables and legumes and consuming less flour, but also intended to alter their eating patterns. Lack of time and the fact that healthy foods are perceived as being more expensive than unhealthy foods were major barriers to behaviour change. Some of the recommendations of the dietary guidelines, particularly those related to enjoying cooking and meals and engaging in it as a social activity, were not represented in consumer accounts. Accompanying policies to the dietary guidelines need to underline the importance of changes in dietary patterns, including greater enjoyment and sharing food preparation and meals in the company with others, address misconceptions about flour, and provide concrete, consumer-derived recommendations on how to enact the guidelines.

    Products derived from the manufacturing or processing of plant based foods: cereals, fruits, vegetables, as well as algae, are sources of abundant dietary fibre. Diets high in dietary fibre have been associated with the reduced risk of cardiovascular disease, diabetes, hypertension, obesity, and gastrointestinal disorders. These fibre-rich products and byproducts can also fortify foods, increase their dietary fibre content and result in healthy products, low in calories, cholesterol and fat. Traditionally, consumers have chosen foods such as whole grains, fruits and vegetables as sources of dietary fibre. Recently, food manufacturers have responded to consumer demand for foods with a higher fibre content by developing products in which highfibre ingredients are used. Different food processing methods also increase the dietary fiber content of food. Moreover, its chemical and physical properties may be affected by food processing. Some of them might even improve the functionality of fibre. Therefore, they may also be applied as functional ingredients to improve physical properties like the physical and structural properties of hydration, oil-holding capacity, viscosity. This study was conducted to examine the effect of different food processing methods on the physicochemical properties of dietary fibre.

    Full Text Available Purpose. To summarize results of studying consumptive qualities of different varieties of potato and define basic characteristics which allow to subsume them under specific economic categories. Methods. Field study, laboratory test, summarizing, analytical approach. Results. Potato varieties entered in the State register of plant varieties suitable to dissemination in Ukraine and new ones especially to be bred at the Institute of Potato Growing of NAAS were studied during the period of 2005–2016 for such basic economic characters as consumptive quality of tubers, content of starch, dry matters, protein, sugar, vitamins, carotenoids and mineral substances as well as aminoacids, color of flesh, suitability for industrial manufacturing of potato products and for purpose of technology. Attention was paid to the good prospects to use varie­ties with purple, blue and red potato tuber flesh with high antioxidant capacity. Potato varieties with above cha­racteristics and their complex combination were defined and described. The requirements of processing industry for potato as a raw material for manufacturing of potato food were given. Conclusions. The major criterion for consumptive qualities of a potato variety and correspondingly division for the commercial use is consumptive quality of tubers, especially content of essential nutrients and their favorable combination, improved taste and cooking quality, high antioxidant capacity, suitability for potato products manufacturing and use for purpose of technology. Potato varieties can be divided for economic purposes into edible, suitable for potato products manufacturing, technical and multipurpose ones.

  5. Flower volatiles, crop varieties and bee responses.

    Directory of Open Access Journals (Sweden)

    Björn K Klatt

    Full Text Available Pollination contributes to an estimated one third of global food production, through both the improvement of the yield and the quality of crops. Volatile compounds emitted by crop flowers mediate plant-pollinator interactions, but differences between crop varieties are still little explored. We investigated whether the visitation of crop flowers is determined by variety-specific flower volatiles using strawberry varieties (Fragaria x ananassa Duchesne and how this affects the pollination services of the wild bee Osmia bicornis L. Flower volatile compounds of three strawberry varieties were measured via headspace collection. Gas chromatography showed that the three strawberry varieties produced the same volatile compounds but with quantitative differences of the total amount of volatiles and between distinct compounds. Electroantennographic recordings showed that inexperienced females of Osmia bicornis had higher antennal responses to all volatile compounds than to controls of air and paraffin oil, however responses differed between compounds. The variety Sonata was found to emit a total higher level of volatiles and also higher levels of most of the compounds that evoked antennal responses compared with the other varieties Honeoye and Darselect. Sonata also received more flower visits from Osmia bicornis females under field conditions, compared with Honeoye. Our results suggest that differences in the emission of flower volatile compounds among strawberry varieties mediate their attractiveness to females of Osmia bicornis. Since quality and quantity of marketable fruits depend on optimal pollination, a better understanding of the role of flower volatiles in crop production is required and should be considered more closely in crop-variety breeding.

    Consumer usage of dietary supplements is prevalent in the United States, and total usage is higher than reported in recent National Health and Nutrition Examination Surveys (NHANES), because these surveys capture usage only in the 30 days prior to the respondent's interview and do not capture occasional and seasonal use throughout the year. We report data from a series of consumer surveys on the full extent of dietary supplement use, on the reasons for supplement use, and on the products most commonly taken, as well as other health habits of supplement users. The Council for Responsible Nutrition (CRN), a trade association of the dietary supplement industry, has contracted with Ipsos Public Affairs to conduct consumer surveys annually since 2000. The surveys have been administered online since 2007 to about 2000 subjects each year. We report 5 years of data (2007 to 2011) on the prevalence of dietary supplement use, as well as more detailed data from the 2011 survey on the products used, the reasons for using supplements, and other health habits of supplement users. The prevalence of supplement use fluctuated within the range of 64% to 69% from 2007 to 2011, and the prevalence of regular supplement use ranged from 48% to 53%, with no statistically significant differences from year to year. Over the 5-year period, the percentage of respondents who said that they regularly used a variety of supplements increased from 28% to 36%, and the increase from 2010 to 2011 was statistically significant. The percentage of respondents who said that they regularly used only a multivitamin, as opposed to a variety of supplements, declined from 24% to 17%, and the decrease from 2007 to 2008 was statistically significant. Detailed results from the 2011 survey confirm that supplement use increases with age and is higher in women than in men. Vitamin or mineral supplements were used by 67% of all respondents in 2011, specialty supplements by 35%, botanicals by 23%, and sports

    The safety and effectiveness of over-the-counter (OTC) drugs are assessed through the Food and Drug Administration's (FDA's) OTC drug review. Prescription drugs are approved through the rigorous new drug application (NDA) process. In contrast, dietary supplements are regulated as foods, and the FDA must determine that a dietary supplement ingredient poses a "significant or unreasonable risk of illness or injury" instead of requiring the manufacturer to provide safety data. According to the FDA, there are more than 29,000 different dietary supplements available to consumers today. This momentum has its roots in consumer interest in health and self-care and suggests that Americans are searching for alternatives to conventional foods for physical and mental well being. The Committee on the Framework for Evaluating the Safety of Dietary Supplements was formed under the auspices of the Food and Nutrition Board that produced a report entitled Dietary Supplements: A Framework for Evaluating Safety. Categories of specific information identified for use are 1) human data, 2) animal studies, 3) in vitro experiments, and 4) information on related substances. Several factors were identified to guide the FDA in applying the framework. Two of these factors are expressed as follows: 1) "the appropriate scientific standard to be used to overturn this basic assumption of safety is to demonstrate significant or unreasonable risk, not prove that an ingredient is unsafe"; and 2) "approaches taken by diverse organizations and governmental bodies, both within and outside the United States, which evaluate the safety and at times efficacy of dietary supplement ingredients, vary in their relevance to the protection of the American public from risks associated with consumption of dietary supplement ingredients".

    Current dietary guidelines for breast cancer patients (BCPs) fail to address adequate dietary intakes of macro- and micronutrients that may improve patients' nutritional status. This review includes information from the PubMed and Biomed Central databases over the last 15 y concerning dietary guidelines for BCPs and the potential impact of a personalized, nutrient-specific diet on patients' nutritional status during and after antineoplastic treatment. Results indicated that BCPs should receive a nutritional assessment immediately after diagnosis. In addition, they should be encouraged to pursue and maintain a healthy body weight [body mass index (BMI; in kg/m 2 ) 20-24.9], preserving their lean mass and avoiding an increase in fat mass. Therefore, after nutritional status diagnosis, a conservative energy restriction of 500-1000 kcal/d could be considered in the dietary intervention when appropriate. Based on the reviewed information, we propose a personalized nutrition intervention for BCPs during and after antineoplastic treatment. Specifications in the nutritional therapy should be based on the patients' nutritional status, dietary habits, schedule, activities, and cultural preferences. BCPs' daily energy intake should be distributed as follows: vegetables (∼75 g/serving) should be encouraged. Garlic and cruciferous vegetables must also be part of the nutrition therapy. Adequate dietary intakes of food-based macro- and micronutrients rich in β-carotene and vitamins A, E, and C can both prevent deterioration in BCPs' nutritional status and improve their overall health and prognosis. © 2017 American Society for Nutrition.

    Iron deficiency is endemic in much of the world, and food system-based approaches to eradication may be viable with new plant breeding approaches to increase the micronutrient content in staple crops. It is thought that conventional plant breeding approaches provide varieties of rice that have 400-500% higher iron contents than varieties commonly consumed in much of Asia. The efficacy of consuming high-iron rice was tested during a 9-mo feeding trial with a double-blind dietary intervention in 192 religious sisters living in 10 convents around metro Manila, the Philippines. Subjects were randomly assigned to consume either high-iron rice (3.21 mg/kg Fe) or a local variety of control rice (0.57 mg/kg Fe), and daily food consumption was monitored. The high-iron rice contributed 1.79 mg Fe/d to the diet in contrast to 0.37 mg Fe/d from the control rice. The 17% difference in total dietary iron consumption compared with controls (10.16 +/- 1.06 vs. 8.44 +/- 1.82 mg/d) resulted in a modest increase in serum ferritin (P = 0.10) and total body iron (P = 0.06) and no increase in hemoglobin (P = 0.59). However, the response was greater in nonanemic subjects for ferritin (P = 0.02) and body iron (P = 0.05), representing a 20% increase after controlling for baseline values and daily rice consumption. The greatest improvements in iron status were seen in those nonanemic women who had the lowest baseline iron status and in those who consumed the most iron from rice. Consumption of biofortified rice, without any other changes in diet, is efficacious in improving iron stores of women with iron-poor diets in the developing world.

    The aim of this study was to find out the influence of selected dietary components on plasma and tissue response of repeated micellar and dietary lutein in aged rats with lutein deficiency. In repeated (16 d) gavage study, micellar lutein was co-ingested with either phosphatidylcholine (PC), lyso-phosphatidylcholine (lysoPC), β-carotene, dietary fiber or vegetable fat (3% soybean oil). In dietary study, rats were fed (4 wk) semi-synthetic diet either with lutein + PC, lutein + dietary fiber or B. alba (lutein source) + PC. The post-prandial plasma and tissue response of lutein was measured by HPLC. Results showed that micellar fat, PC and lysoPC significantly (P ≤ 0.05) increased the lutein levels in plasma (31.1%, 26.8%, and 34.9%), liver (27.4%, 29.5%, and 8.6%), and eyes (63.5%, 90.2%, and 86%) compared to the control group (group gavaged micelles with no dietary components studied). Similarly, dietary study showed an enhanced plasma, liver, and eye lutein levels by 44.8%, 24.1%, and 42.0% (lutein + PC group) and 51.7%, 39.8%, and 31.7% (B.alba + PC group), respectively compared to control. The activity of antioxidant enzymes in plasma and liver of both the studies were also affected compared to control. Result reveals, that PC enhance the intestinal absorption of both micellar and dietary lutein which is either in free or bound form with food matrices in aged rats with lutein deficiency. Hence, PC at a concentration used in this study can be considered to improve the lutein bioavailability in lutein deficiency. Lutein and zeaxanthin are macular pigments acquired mostly from greens, that play an significant role in protecting vision from Age related macular degeneration (AMD). However, their biological availability is poor and affected by dietary components. This study demonstrates the positive influence of dietary PC and lyso PC in improving intestinal uptake of lutein. Our previous and present finding shows there is a possibility of developing functional

    Full Text Available Probiotic bacteria are known to harbor intrinsic and mobile genetic elements that confer resistance to a wide variety of antibiotics. Their high amounts in dietary supplements can establish a reservoir of antibiotic resistant genes in the human gut. These resistant genes can be transferred to pathogens that share the same intestinal habitat thus resulting in serious clinical ramifications. While antibiotic resistance of probiotic bacteria from food, human and animal sources have been well-documented, the resistant profiles of probiotics from dietary supplements have only been recently studied. These products are consumed with increasing regularity due to their health claims that include the improvement of intestinal health and immune response as well as prevention of acute and antibiotic-associated diarrhea and cancer; but, a comprehensive risk assessment on the spread of resistant genes to human health is lacking. Here, we highlight recent reports of antibiotic resistance of probiotic bacteria isolated from dietary supplements, and propose complementary strategies that can shed light on the risks of consuming such products in the context of a global widespread of antibiotic resistance. In concomitant with a broader screening of antibiotic resistance in probiotic supplements is the use of computational simulations, live imaging and functional genomics to harvest knowledge on the evolutionary behavior, adaptations and dynamics of probiotics studied in conditions that best represent the human gut including in the presence of antibiotics. The underlying goal is to enable the health benefits of probiotics to be exploited in a responsible manner and with minimal risk to human health.

    Dietary fiber and bioactive compounds are widely used as functional ingredients in processed foods. The market in this field is competitive and the development of new types of quality ingredients for the food industry is on the rise. Opuntia ficus-indica (cactus pear) produces edible tender stems (cladodes) and fruits with a high nutritional value in terms of minerals, protein, dietary fiber and phytochemicals; however, around 20% of fresh weight of cladodes and 45% of fresh weight of fruits are by-products. The objective of this study was therefore to determine the nutritional value of by-products obtained from cladodes and fruits from two varieties of Opuntia ficus-indica, examining their dietary fiber and natural antioxidant compound contents in order to obtain quality ingredients for functional foods and increase the added value of these by-products.

    Full Text Available Microsatellite polymorphism was studied in a sample of 39 traditional rice (Oryza sativa L. varieties and 11 improved varieties widely planted in Cuba. The study was aimed at assessing the extent of genetic variation in traditional and improved varieties and to establish their genetic relationship for breeding purposes. Heterozygosity was analyzed at each microsatellite loci and for each genotype using 10 microsatellite primer pairs. Between varieties genetic relationship was estimated. The number of alleles per microsatellite loci was 4 to 8, averaging 6.6 alleles per locus. Higher heterozygosity (H was found in traditional varieties (H TV = 0.72 than in improved varieties (H IV = 0.42, and 68% of the total microsatellite alleles were found exclusively in the traditional varieties. Genetic diversity, represented by cluster analysis, indicated three different genetic groups based on their origin. Genetic relationship estimates based on the proportion of microsatellite loci with shared alleles indicated that the majority of traditional varieties were poorly related to the improved varieties. We also discuss the more efficient use of the available genetic diversity in future programs involving genetic crosses.

Methods: This was a cross-sectional study involving 290 mothers (mean age = 27, standard deviation = 5.32 with child 1–2-year-old attending maternal and child health section of health centers in Rasht, Iran. To represent the socioeconomic status of the participants, 6 centers out of 15 were selected from three different socioeconomic areas (low-, middle-, and high-income areas. Mothers completed a questionnaire assessing intention and belief-based items of theory of planned behavior. Correlations and multiple regression analyses were performed. Results: The mean age of mothers was 27 ± 5.33 (27–43 years. Regression analyses revealed that among behavioral beliefs, the perception that adherence to dietary diversity would lead to improve children's growth was the significant predictor of intention (β = 0.13,P= 0.04. Regarding normative beliefs, perceived social pressure from health-care professionals to adherence to dietary diversity significantly predicted intention (β = 0.15,P= 0.01. Among control beliefs, the perception that daily pressures made difficult adherence to dietary diversity was the key determinant (β = 0.19,P= 0.01. Conclusions: Findings of this study represent the important beliefs that can be addressed in development planning aimed at modifying mothers' child complementary feeding practices.

    The Dietary Approaches to Stop Hypertension (DASH) diet is a proven way to prevent and control hypertension and other chronic disease. Because the DASH diet emphasizes plant-based foods, including vegetables and grains, adhering to this diet might also bring about environmental benefits, including lower associated production of greenhouse gases (GHGs). The objective was to examine the interrelation between dietary accordance with the DASH diet and associated GHGs. A secondary aim was to examine the retail cost of diets by level of DASH accordance. In this cross-sectional study of adults aged 39-79 y from the European Prospective Investigation into Cancer and Nutrition-Norfolk, United Kingdom cohort (n = 24,293), dietary intakes estimated from food-frequency questionnaires were analyzed for their accordance with the 8 DASH food and nutrient-based targets. Associations between DASH accordance, GHGs, and dietary costs were evaluated in regression analyses. Dietary GHGs were estimated with United Kingdom-specific data on carbon dioxide equivalents associated with commodities and foods. Dietary costs were estimated by using national food prices from a United Kingdom-based supermarket comparison website. Greater accordance with the DASH dietary targets was associated with lower GHGs. Diets in the highest quintile of accordance had a GHG impact of 5.60 compared with 6.71 kg carbon dioxide equivalents/d for least-accordant diets (P dietary costs, with the mean cost of diets in the top quintile of DASH scores 18% higher than that of diets in the lowest quintile (P < 0.0001). Promoting wider uptake of the DASH diet in the United Kingdom may improve population health and reduce diet-related GHGs. However, to make the DASH diet more accessible, food affordability, particularly for lower income groups, will have to be addressed.

    Full Text Available Rosaceae (strawberry, cherry, blackberry, red raspberry, and black raspberry dietary supplements and food products (total n = 74 were purchased and analyzed to determine their anthocyanin concentrations and profiles. Eight of the 33 dietary supplements had no detectable anthocyanins (five samples or were adulterated with anthocyanins from unlabeled sources (three samples. Five of 41 food products contained no detectable anthocyanins. In mg per serving, the dietary supplements tested contained 0.02–86.27 (average 10.00, and food products contained 0.48–39.66 (average 7.76. Anthocyanin levels between the dietary supplements and food products were not significantly different in mg per serving. Individual anthocyanin profiles can be used to evaluate quality of Rosaceae food products and dietary supplements. These findings show that increasing anthocyanin content and reducing adulteration could improve the quality of Rosaceae products available in the marketplace.

    2017-11-01

    Full Text Available The nutritional evaluation of quality protein maize (QPM in feeding trials has proved its nutritional superiority over non-QPM varieties for human and livestock consumption. The present paper reviews some of the most recent achievements in development of QPM varieties using both conventional and molecular breeding under stressed and non-stressed environments. It is evident that numerous QPM varieties have been developed and released around the world over the past few decades. While the review points out some gaps in information or research efforts, challenges associated with adoption QPM varieties are highlighted and suggestions to overcome them are presented. The adoption of released varieties and challenges facing QPM production at the farmer level are also mentioned. Several breeding methods have been conventionally used to develop QPM varieties in stressed (drought, low soil nitrogen, resistance to grey leaf spot, Turcicum leaf blight, ear rot, and Striga and non-stressed environments. At least three genetic loci have been found to be implicated in controlling the levels of a protein synthesis factor correlated with lysine. They have been mapped on chromosomes 2, 4, and 7. While the use of molecular approaches will improve the efficiency and speed of variety development, the cost implications might limit the use of these technologies in the developing world. More emphasis should be given to breeding QPM for tolerance to environmental stresses, such as low soil pH, heat, and combined heat and drought stress. The post-harvest attack of QPM grains should also be considered. The adoption of QPM genotypes by farmers has been found to be limited mainly due to the minimal collaboration between maize breeders, farmers, agricultural extension workers, and other relevant stakeholders, as well as the need for isolating QPM varieties from normal maize. Therefore, there is need to use participatory plant breeding (PPB and/or participatory variety

    The ecology of Neanderthals is a pressing question in the study of hominin evolution. Diet appears to have played a prominent role in their adaptation to Eurasia. Based on isotope and zooarchaeological studies, Neanderthal diet has been reconstructed as heavily meat-based and generally similar across different environments. This image persists, despite recent studies suggesting more plant use and more variation. However, we have only a fragmentary picture of their dietary ecology, and how it may have varied among habitats, because we lack broad and environmentally representative information about their use of plants and other foods. To address the problem, we examined the plant microremains in Neanderthal dental calculus from five archaeological sites representing a variety of environments from the northern Balkans, and the western, central and eastern Mediterranean. The recovered microremains revealed the consumption of a variety of non-animal foods, including starchy plants. Using a modeling approach, we explored the relationships among microremains and environment, while controlling for chronology. In the process, we compared the effectiveness of various diversity metrics and their shortcomings for studying microbotanical remains, which are often morphologically redundant for identification. We developed Minimum Botanical Units as a new way of estimating how many plant types or parts are present in a microbotanical sample. In contrast to some previous work, we found no evidence that plant use is confined to the southern-most areas of Neanderthal distribution. Although interpreting the ecogeographic variation is limited by the incomplete preservation of dietary microremains, it is clear that plant exploitation was a widespread and deeply rooted Neanderthal subsistence strategy, even if they were predominately game hunters. Given the limited dietary variation across Neanderthal range in time and space in both plant and animal food exploitation, we argue that

    Over the past 50 years, dietary restriction (DR) has been shown to extend the life span of a wide variety of organisms. A hallmark feature of DR is improved glucose homeostasis resulting in increased glucose tolerance and insulin sensitivity of animals ranging from rodents to humans. In this study, we demonstrate the early effects of varying levels of DR on glucose tolerance. Within 10 days of 40% DR, glucose tolerance was significantly improved and by 120 days; 10 and 20% DR also showed enhanced glucose tolerance. All three levels of DR showed reduced adiposity, increased expression of genes involved in fat turnover, and a reduction in the expression for markers of inflammation. Studies have shown that mice fed a DR diet retained metabolic memory in terms of improved glucose tolerance even after DR is discontinued. We show that 40% DR not only has an early effect on glucose tolerance but also maintained it after DR was discontinued for 2 months. Therefore, improvement in glucose tolerance is brought about by all three levels of DR but the metabolic memory is not dose responsive.

    Full Text Available Background. Several studies showed that regular gymnasium users use various dietary supplements without comprehension of their potential risks. Objective. To determine the prevalence and dietary supplement intake and assess the awareness of supplement use among regular gymnasium users in Riyadh, Saudi Arabia. Methods. A descriptive cross-sectional study was conducted among regular gymnasium users in Riyadh, Saudi Arabia, between April 2015 and June 2015. A validated structured questionnaire was used. Results. The study included 299 participants. Of these 113 (37.8% were dietary supplements users and this was more common among males than females (44.7% versus 16.4%. Gender based analysis showed that males were exercising more frequently than females and the type of cardiovascular exercise was more among them. The most commonly used supplements were whey protein (22.1%, amino acids (16.8%, multivitamins (16.8%, creatine (11.5%, and omega 3 (11.5%. The reasons for taking dietary supplements were to improve body shape (47.7%, increase health (44.2%, and improve performance (41.5%. Conclusion. Most of the information about supplements was obtained from unreliable sources. More studies are needed to better understand supplements use and their impact on health in Saudi Arabia.

    Rainfall variability has a significant impact on crop production with manifestations in frequent crop failure in semiarid areas. This study used the parameterized APSIM crop model to investigate how rainfall variability may affect yields of improved sorghum varieties based on long-term historical rainfall and projected climate. Analyses of historical rainfall indicate a mix of nonsignificant and significant trends on the onset, cessation, and length of the growing season. The study confirmed that rainfall variability indeed affects yields of improved sorghum varieties. Further analyses of simulated sorghum yields based on seasonal rainfall distribution indicate the concurrence of lower grain yields with the 10-day dry spells during the cropping season. Simulation results for future sorghum response, however, show that impacts of rainfall variability on sorghum will be overridden by temperature increase. We conclude that, in the event where harms imposed by moisture stress in the study area are not abated, even improved sorghum varieties are likely to perform poorly.

    Full Text Available Abstract Despite its use in our diet for hundreds of years, hempseed has surprisingly little research published on its physiological effects. This may have been in the past because the psychotropic properties wrongly attributed to hemp would complicate any conclusions obtained through its study. Hemp has a botanical relationship to drug/medicinal varieties of Cannabis. However, hempseed no longer contains psychotropic action and instead may provide significant health benefits. Hempseed has an excellent content of omega-3 and omega-6 fatty acids. These compounds have beneficial effects on our cardiovascular health. Recent studies, mostly in animals, have examined the effects of these fatty acids and dietary hempseed itself on platelet aggregation, ischemic heart disease and other aspects of our cardiovascular health. The purpose of this article is to review the latest developments in this rapidly emerging research field with a focus on the cardiac and vascular effects of dietary hempseed.

    Cowpea is traditionally cultivated in some regions of southern Europe for its dried seeds; however, there is a scarcity of information on the quality and dietary characteristics of fresh pods, which are occasionally used in folk diets. This paper aims at covering this gap in knowledge, thereby contributing to the dissemination of fresh cowpea pods as a novel product for the market. The quality and dietary characteristics of pods from 37 accessions (Vigna unguiculata ssp. unguiculata and ssp. sesquipedalis) grown in southern Europe were assessed in an attempt to provide information on pod quality and nutritional properties and to identify relationships between quality traits and accession origin. Pods from the sesquipedalis accessions were heavier and larger, and reached commercial maturity 2 days later, than those from the unguiculata accessions. There were also large differences in the quality and dietary characteristics of the accessions. The pods of most accessions were rich in proteins, chlorophylls, carotenoids and phenolics, and showed high antioxidant activity and low concentrations of nitrates and raffinose-family oligosaccharides. Cluster analysis based on quality, dietary or antinutritional traits did not reveal any apparent grouping among the accessions. All the quality characteristics were independent of accession origin and subspecies. Most of the accessions produced fresh pods of good quality and high dietary value, suitable for introduction in the market and/or for use as valuable genetic material for the development of new improved varieties. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

    As part of study on ''Reference Asian Man'' to strengthen radiation protection, the data on the dietary consumption patterns of the Asian region were collected. Eight provided dietary data - Bangladesh, China, India, Indonesia, Japan, Pakistan, Philippines, and Viet Nam. Whereas the dietary information from Bangladesh, Indonesia, Pakistan and Viet Nam are preliminary in nature, the dietary information from China, India, Japan and Philippines, on the other hand, is quite substantial. The population of the countries from which sufficient dietary data are available represents more than 2/3 of the population of the Asian region. The details of the individual data available on dietary parameters from different Asian countries are listed below

    This study aimed to provide an overview of available literature on interventions aiming to improve dietary intake among university students. A systematic review was conducted following the PRISMA guidelines. Web of Science, PubMed, PsycINFO and SPORTDiscus were searched for relevant articles. Risk of bias was assessed using the Academy of Nutrition and Dietetics Quality Criteria Checklist for Primary Research. Twenty studies were identified, consisting of 12 randomised controlled trials, 1 quasi-experiment and 7 pre-experiments. Six studies were conducted outside the US. Risk of bias assessment revealed an average quality score of 5.8/10. Of the 13 interventions which were effective in improving students' dietary intake, 8 used an intrapersonal approach, with 6 of them using the web or some kind of media to facilitate the intervention. The 5 remaining studies used an environmental (point-of-purchase) approach. Only 1 intervention, using 10 web-based lessons, based on non-diet principles and focused on eating competence and size acceptance to promote healthy eating, was found to be effective in the long term. Nutrition education, enhancing self-regulation components towards dietary intake (often facilitated by the worldwide web or other media devices), and point-of-purchase messaging strategies may improve university or college students' dietary intake. Future high quality randomised controlled trials should evaluate sustainability of intervention effects, as well as further investigate the effectiveness of realistic and low-cost environmental (preferably combined with intrapersonal) interventions which can easily and instantly reach a great part of the university population.

    Dietary patterns represent a broader picture of food consumption, and are better correlated with a variety of health outcomes. However, few studies have been conducted to explore the associations between dietary patterns and obesity in Southwest China. Data from the 2010-2012 National Nutrition Survey in the province of Yunnan, Southwest China, were analyzed ( n = 1604, aged 18-80 years). Dietary data were collected using the 24 h dietary recall over three consecutive days. Height, weight, and waist circumference were measured following standard methods. Exploratory factor analysis was used to identify dietary patterns. Logistic regression was used to explore the association between dietary patterns and obesity. Three distinct dietary patterns were identified, which were labeled as traditional, modern, and tuber according to their key components. With potential confounders adjusted, adults in the highest quartile of the modern pattern were at higher risk of general and central obesity (odds ratio (OR) 1.95, 95% confidence interval (CI) 1.15-3.48; OR 2.01, 95% CI 1.37-2.93). In contrast, adults in the highest quartile of the tuber pattern were at lower risk of general and central obesity (OR 0.34, 95% CI 0.15-0.61; OR 0.64, 95% CI 0.43-0.95) but at higher risk of underweight (OR 2.57, 95% CI 1.20-6.45). No significant association was found between the traditional pattern and obesity. Moreover, dietary pattern differences occurred due to the differences in socio-demographic characteristics. In conclusion, the modern dietary pattern was positively, and the tuber pattern negatively, associated with general and central obesity among adults in Southwest China.

    U.S. nutrition surveys find that intakes of many nutrients fall short of recommendations. The majority of U.S. adults use multivitamins and other dietary supplements as one means of improving nutrient intakes. Some policy makers and health professionals appear reluctant to recommend routine use of dietary supplements to fill nutrient gaps in the diet, in part because they are concerned that people will view the supplements as a substitute for dietary improvement and that the use of supplements may lead to overconsumption of micronutrients. Surveys find that in fact users of dietary supplements tend to have better diets and adopt other healthy habits, suggesting that the supplements are viewed as one aspect of an overall effort to improve wellness. Furthermore, evidence demonstrates that the incidence of excess micronutrient intake is low. We report the results of a survey probing consumer attitudes about the role of dietary supplements. The Council for Responsible Nutrition funded a survey to measure consumer attitudes about the role of multivitamins, calcium and/or vitamin D supplements, and other supplements in improving dietary intakes. The research was designed and analyzed by FoodMinds and was fielded using Toluna's On-line Omnibus. The weighted sample of 2159 respondents is representative of U.S. adults. Nearly 90% of the survey respondents agreed that multivitamins and supplements of calcium and/or vitamin D can help meet nutrient needs when desirable intakes are not achieved through food alone. At the same time, 80% agreed that dietary supplements should not be used to replace healthy dietary or lifestyle habits, and 82% agreed that people considering taking a high dose, single nutrient supplement should talk with their physician. These results provide additional support for the conclusion that the vast majority of consumers recognize that multivitamins and other supplements can help fill nutrient gaps but should not be viewed as replacements for a healthy

    Severe malnutrition and wasting are considered hallmarks of advanced malignant disease, and clinical research into anorexia-cachexia therapy and nutritional support for cancer patients is ongoing. However, information on typical dietary intakes and food choices for this population is notably lacking; proposed therapies for anorexia and wasting are not framed within the context of current intake. The objective of the study was to characterize the food intake patterns of patients with advanced cancer. Patients with advanced cancer (n = 151) recruited from a regional cancer center and palliative-care program completed a 3-d dietary record a mean (+/-SD) 8 +/- 7 mo before death. Food items were categorized according to macronutrient content and dietary use and subsequently entered into cluster analysis. Wide variations in intakes of energy (range: 4-53 kcal . kg body wt(-1) . d(-1); x +/- SD: 25.1 +/- 10.0 kcal . kg body wt(-1) . d(-1)) and protein (range: 0.2-2.7 g . kg body wt(-1) . d(-1); x +/- SD: 1.0 +/- 0.4 g . kg body wt(-1) . d(-1)) were observed. Even the subjects with the highest intakes had a recent history of weight loss, which suggests that the diets of those persons were consistently inadequate for weight maintenance. Cluster analysis found 3 dietary patterns that differed in food choice and caloric intake. Low intakes and a high risk of weight loss were associated with decreased frequency of eating and dietary profiles with little variety and unusually high proportions of liquids. These data provide a glimpse into dietary habits toward the end of life. Unique dietary patterns were found in this nutritionally vulnerable patient population.

    Weight gain after stopping smoking potentially counteracts improvements in cardiometabolic risks. We investigated changes in metabolic syndrome (MetS) components and homeostasis assessment model insulin resistance (HOMA-IR) in smokers given dietary counseling during their quit attempt. Smokers (≥10 cigarettes/day) with BMI 25-40 kg/m 2 were randomized to a low-carbohydrate or low-fat diet and treated with a standard course of varenicline for 12 weeks. Quitters were assessed according to the Russell standard (≤5 cigarettes after the quit date) validated with expired breath carbon monoxide (CO) vs 0.3 ± 3.1 kg; p = 0.7) and change in waist circumference (-2.0 ± 3.8 cm vs -0.9 ± 3.9 cm; p = 0.2). Changes in triglyceride concentrations (-0.16 ± 0.52 mmol/l vs 0.21 ± 0.95 mmol/l; p = 0.015) and diastolic blood pressure (-0.9 ± 6 mmHg vs 1.9 ± 8 mmHg; p = 0.039) were more favorable in quitters. Changes in other cardiometabolic risks and HOMA-IR did not differ between quitters and continuous smokers, nor did energy intake or resting metabolic rate. Dyslipidemia and blood pressure improved and no early weight gain was seen in quitters, suggesting that dietary intervention can mitigate some of the effects of stopping smoking on cardiometabolic risk factors in overweight and obese smokers.

    Full Text Available Antibiotics and chemical treatments are often used as disease control strategy. A prophylactic and alternative method to this chemical approach are the probiotics [1]. Probiotics are defined as "live microorganisms which when administered in adequate amounts confer a health benefit on the host" (FAO, 2001. The benefits of probiotic treatments are improvements in host nutritional retention [2], antagonistic properties to bacterial pathogen proliferation [3], modulation of immune responses [4], among others. Temperature plays a major role in dietary nutrient utilization and immune responses in fish, and have a modulatory effect on probiotic activity in intestine. The current study evaluated the use of a dietary probiotic supplementation in European seabass (Dicentrarchus labrax, one of the most important fish species in Southern Europe. Fish were fed on a multi-species probiotic (Bacillus sp., Pedicoccus sp., Enterococcus sp., Lactobacillus sp. , reared under 3 different temperatures (17, 20 and 23 ºC for 70 days. Fish were pair-fed, fixed to the voluntary feed intake of fish reared at 17 º C, in order to have similar probiotic intake among the temperature groups. Final body weight tripled initial weight (12.7 to 30.7g. At the end of the growth trial, all fish were subjected to a handling stress, in which stocking density increased by 6 fold (from 4 kg/m3 to 25 kg/m3, followed by a 15 min chase with a pole. Growth performance was not affected by the dietary treatment. Post-stress cumulative mortality were significantly higher in the 17ºC control group (figure 1A. Digestive enzymes activity were significantly affected by temperature and diet interaction. The activity ratio of amylase to trypsin (figure 1B increased with temperature and dietary probiotic supplementation, an indication that probiotic treatment at 23oC have a positive influence on the metabolic flexibility of carbohydrate-protein utilization.

    Dietary iodine is essential for thyroid hormone production. Although U.S. dietary iodine is generally adequate, some groups, especially women of childbearing age, are at risk for mild iodine deficiency. Children's average urinary iodine is higher than that of adults. U.S. dietary iodine sources have not been assessed recently. A survey of iodine content in 20 brands of bread, 18 brands of cows' milk, and eight infant formulae was performed between 2001 and 2002. Three bread varieties contained more than 300 microg iodine per slice. Iodine content in other brands was far lower (mean +/- sd, 10.1 +/- 13.2 microg iodine/slice). All cows' milk samples had at least 88 microg iodine/250 ml, ranging from 88-168 microg (116.0 +/- 22.1 microg/250 ml). Infant formulae values ranged from 16.2 to 56.8 microg iodine/5 oz (23.5 +/- 13.78 microg/5 oz). The public should be aware of the need for adequate dietary iodine intake and should be aware that ingredient lists do not reflect the iodine content of foods.

    Dietary assessment has come under much criticism of late to the extent that it has been questioned whether self-reported methods of dietary assessment are worth doing at all. Widespread under-reporting of energy intake, limitations due to memory, changes to intake due to the burden of recording and social desirability bias all impact significantly on the accuracy of the dietary information collected. Under-reporting of energy intakes has long been recognized as a problem in dietary research with doubly labeled water measures of energy expenditure uncovering significant under-reporting of energy intakes across different populations and different dietary assessment methods. In this review we focus on dietary assessment with children with particular attention on the 24-hour dietary recall method. We look at the level of under-reporting of energy intakes and how this tends to change with age, gender and body mass index. We discuss potential alternatives to self-reported (or proxy-reported) dietary assessment methods with children, such as biomarkers, and how these do not enable the collection of information important to public health nutrition such as the cooking method, the mixture of foods eaten together or the context in which the food is consumed. We conclude that despite all of the challenges and flaws, the data collected using self-reported dietary assessment methods are extremely valuable. Research into dietary assessment methodology has resulted in significant increases in our understanding of the limitations of self-reported methods and progressive improvements in the accuracy of the data collected. Hence, future investment in dietary surveillance and in improving self-reported methods of intake can make vital contributions to our understanding of dietary intakes and are thus warranted.

    One of the greatest challenges in nutritional epidemiology is improving upon traditional self-reporting methods for the assessment of habitual dietary intake. The aim of this study was to evaluate the relative validity of a new method known as the current-day dietary recall (or current-day recall), based on a smartphone app called 12-hour dietary recall, for determining the habitual intake of a series of key food and drink groups using a food frequency questionnaire (FFQ) and four dietary records as reference methods. University students over the age of 18 years recorded their consumption of certain groups of food and drink using 12-hour dietary recall for 28 consecutive days. During this 28-day period, they also completed four dietary records on randomly selected days. Once the monitoring period was over, subjects then completed an FFQ. The two methods were compared using the Spearman correlation coefficient (SCC), a cross-classification analysis, and weighted kappa. A total of 87 participants completed the study (64% women, 56/87; 36% men, 31/87). For e-12HR versus FFQ, for all food and drink groups, the average SCC was 0.70. Cross-classification analysis revealed that the average percentage of individuals classified in the exact agreement category was 51.5%; exact agreement + adjacent was 91.8%, and no participant (0%) was classified in the extreme disagreement category. The average weighted kappa was 0.51. For e-12HR versus the four dietary records, for all food and drink groups, the average SCC was 0.63. Cross-classification analysis revealed that the average percentage of individuals classified in the exact agreement category was 47.1%; exact agreement + adjacent was 89.2%; and no participant (0%) was classified in the extreme disagreement category. The average weighted kappa was 0.47. Current-day recall, based on the 12-hour dietary recall app, was found to be in good agreement with the two reference methods (FFQ & four dietary records), demonstrating its

    Dates (Phoenix dactylifera L.) are distributed worldwide as major food complement providing a source of sugars and dietary fiber as well as macro- and micronutrients. Although phytochemical analyses of date fruit non-volatile metabolites have been reported, much less is known about the aroma given off by the fruit, which is critical for dissecting sensory properties and quality traits. Volatile constituents from 13 date varieties grown in Egypt were profiled using SPME-GCMS coupled to multivariate data analysis to explore date fruit aroma composition and investigate potential future uses by food industry. A total of 89 volatiles were identified where lipid-derived volatiles and phenylpropanoid derivatives were the major components of date fruit aroma. Multivariate data analyses revealed that 2,3-butanediol, hexanal, hexanol and cinnamaldehyde contributed the most to classification of different varieties. This study provides the most complete map of volatiles in Egyptian date fruit, with Siwi and Sheshi varieties exhibiting the most distinct aroma among studied date varieties.

    Sesame varieties/genotypes showed a good response to radiation with gamma rays and treatments with EMS. In M 1 both gamma rays and EMS influenced germination, seedling height, survival of plants and pollen fertility/sterility, producing deleterious effects on these characters. Compared to black seeded genotypes, white seeded ones are more susceptible to radiation. Both gamma rays and EMS produced various types of morphological variations in M 2 generation. These were dwarf plant mutants, mottled and fleshy leaved mutants (sterile), fasciated stem, flower colour, altered phyllotaxy, early, uniculm, capsule size variations, multiple capsule/leaf axil, seed coat colour variations, indehiscent and semi-indehiscent type mutants. Moreover, studies on quantitative characters including seed yield revealed the induction of mutants in both positive and negative directions for such traits which made a good scope of selection of desirable mutants in M 2 generation. Mutants selected in M 2 were raised in M 3 in plant to progeny rows and further selection was made. Compared to the M 2 generation, the range of family means became narrower in M 3 which indicated the effectiveness of selection in the M 2 . True breeding lines isolated in M 3 generation have given potentially higher seed and oil yield in a preliminary yield trial in M 4 compared to source. Six promising mutant lines were evaluated in M 4 , M 5 , M 6 , M 7 and M 8 generations for seed yield and other agronomic parameters at various locations of Bangladesh under variable environments. Mutants SM5, SM7 have produced significantly higher seed yields at all locations with 50-52% oil content compared to 40-44% oil content in the source varieties. Some mutants were tolerant to stem rot and sesame mosaic in most of the locations. The increased yield was due to higher number of capsules/leaf axil, longer capsules with continuous bearing and increased number of seeds/capsule. It was also observed that white seeded mutants

    Flavonoids are the most common group of polyphenolic compounds and abundant in dietary fruits and vegetables. Diet high in vegetables or dietary flavonoid supplements is associated with reduced mortality rate for patients with breast cancer. Many studies have been proposed for mechanisms linking flavonoids to improving chemotherapy efficacy in many types of cancers, but data on this issue is still limited. Herein, we report on a new mechanism through which dietary flavonoids inhibit DNA damage checkpoints and repair pathways. We found that dietary flavonoids could inhibit Chk1 phosphorylation and decrease clonogenic cell growth once breast cancer cells receive ultraviolet irradiation, cisplatin, or etoposide treatment. Since the ATR-Chk1 pathway mainly involves response to DNA replication stress, we propose that flavonoid derivatives reduce the side effect of chemotherapy by improving the sensitivity of cycling cells. Therefore, we propose that increasing intake of common dietary flavonoids is beneficial to breast cancer patients who are receiving DNA-damaging chemotherapy, such as cisplatin or etoposide-based therapy. - Highlights: • First report on inhibition of both DNA damage and repair by dietary flavonoids • Dietary flavonoids inhibit cisplatin- and UV-induced Chk1 phosphorylation. • Flavonoids combined with cisplatin or UV treatment show notable growth inhibition. • Promising treatment proposal for patients who are receiving adjuvant chemotherapy

    Improving maternal and child nutrition in resource-poor settings requires effective use of limited resources, but priority-setting is constrained by limited information about program costs and impacts, especially for interventions designed to improve diet quality. This study utilized a mixed methods approach to identify, describe and estimate the potential costs and impacts on child dietary intake of 12 nutrition-sensitive programs in Ethiopia, Nigeria and India. These potential interventions included conditional livestock and cash transfers, media and education, complementary food processing and sales, household production and food pricing programs. Components and costs of each program were identified through a novel participatory process of expert regional consultation followed by validation and calibration from literature searches and comparison with actual budgets. Impacts on child diets were determined by estimating of the magnitude of economic mechanisms for dietary change, comprehensive reviews of evaluations and effectiveness for similar programs, and demographic data on each country. Across the 12 programs, total cost per child reached (net present value, purchasing power parity adjusted) ranged very widely: from 0.58 to 2650 USD/year among five programs in Ethiopia; 2.62 to 1919 USD/year among four programs in Nigeria; and 27 to 586 USD/year among three programs in India. When impacts were assessed, the largest dietary improvements were for iron and zinc intakes from a complementary food production program in Ethiopia (increases of 17.7 mg iron/child/day and 7.4 mg zinc/child/day), vitamin A intake from a household animal and horticulture production program in Nigeria (335 RAE/child/day), and animal protein intake from a complementary food processing program in Nigeria (20.0 g/child/day). These results add substantial value to the limited literature on the costs and dietary impacts of nutrition-sensitive interventions targeting children in resource

    Dietary supplements are increasingly marketed to and consumed by the American public for a variety of purported health benefits. On 9 September 2013, the Hawaii Department of Health (HDOH) was notified of a cluster of acute hepatitis and fulminant hepatic failure among individuals with exposure to the dietary supplement OxyELITE Pro™ (OEP). HDOH conducted an outbreak investigation in collaboration with federal partners. Physicians were asked to report cases, defined as individuals with acute onset hepatitis of unknown etiology on or after 1 April 2013, a history of weight-loss/muscle-building dietary supplement use during the 60 days before illness onset, and residence in Hawaii during the period of exposure. Reported cases' medical records were reviewed, questionnaires were administered, and a product investigation, including chemical analyses and traceback, was conducted. Of 76 reports, 44 (58%) met case definition; of these, 36 (82%) reported OEP exposure during the two months before illness. No other common supplements or exposures were observed. Within the OEP-exposed subset, two patients required liver transplantation, and a third patient died. Excessive product dosing was not reported. No unique lot numbers were identified; there were multiple mainland distribution points, and lot numbers common to cases in Hawaii were also identified in continental states. Product analysis found consumed products were consistent with labeled ingredients; the mechanism of hepatotoxicity was not identified. We report one of the largest statewide outbreaks of dietary supplement-associated hepatotoxicity. The implicated product was OEP. The increasing popularity of dietary supplements raises the potential for additional clusters of dietary supplement-related adverse events. Copyright © 2015 John Wiley & Sons, Ltd.

    Achieving nutritional requirements for pregnant and lactating mothers in rural households while maintaining the intake of local and culture-specific foods can be a difficult task. Deploying a linear goal programming approach can effectively generate optimal dietary patterns that incorporate local and culturally acceptable diets. The primary objective of this study was to determine whether a realistic and affordable diet that achieves nutritional goals for rural pregnant and lactating women can be formulated from locally available foods in Tanzania. A cross sectional study was conducted to assess dietary intakes of 150 pregnant and lactating women using a weighed dietary record (WDR), 24 h dietary recalls and a 7-days food record. A market survey was also carried out to estimate the cost per 100 g of edible portion of foods that are frequently consumed in the study population. Dietary survey and market data were then used to define linear programming (LP) model parameters for diet optimisation. All LP analyses were done using linear program solver to generate optimal dietary patterns. Our findings showed that optimal dietary patterns designed from locally available foods would improve dietary adequacy for 15 and 19 selected nutrients in pregnant and lactating women, respectively, but inadequacies remained for iron, zinc, folate, pantothenic acid, and vitamin E, indicating that these are problem nutrients (nutrients that did not achieve 100% of their RNIs in optimised diets) in the study population. These findings suggest that optimal use of local foods can improve dietary adequacy for rural pregnant and lactating women aged 19-50 years. However, additional cost-effective interventions are needed to ensure adequate intakes for the identified problem nutrients.

    The advantage of supplemental sodium bicarbonate (NaHCO3) on eggshell quality in laying hens changes with age. Besides increasing calcium (Ca) secretion in the eggshell gland, it may improve Ca absorption in the intestine or kidney. Hy-Line Brown layers (n = 384), 25 weeks of age, were allocated to two treatment groups in two experiments, each of which included 4 replicates of 24 hens. Hens were fed a basal diet (control) or the basal diet containing 3 g NaHCO3 g/kg for 50 or 20 weeks in Experiment 1 or 2, respectively. A 24-h continuous lighting regimen was used to allow hens to consume the dietary supplements during the period of active eggshell formation. In Experiment 1, particularly from 25 to 50 weeks of age, and in Experiment 2, NaHCO3 supplementation favoured hen-d egg production at the expense of lower egg weight. The increased eggshell thickness should have nothing to do with the additional eggshell formation, because of the unchanged egg mass and daily eggshell calcification. At 35 weeks of age in both experiments, NaHCO3 supplementation increased duodenal expression of calbindin-d28k (CaBP-D28k) protein, contributing to higher Ca retention and balance. From 50 to 75 weeks of age in Experiment 1, the hens had little response to NaHCO3 supplementation and showed a negative trend on eggshell thickness and strength. It is concluded that dietary supplementation with 3 g NaHCO3 g/kg improves Ca absorption and eggshell quality of laying hens during the peak but not late production period, with the introduction of continuous lighting.

    One of the peaceful applications of atomic energy is in the field of agriculture. It finds application in crop improvement, crop nutrition, crop protection and food preservation. Genetic improvement of crop plants is a continuous endeavor. Success of a crop improvement programme depends on the availability of large genetic variability, which a plant breeder can combine to generate new varieties. In nature, occurrence of natural variability in the form of spontaneous mutations is extremely low (roughly 10 -6 ), which can be enhanced to several fold (approximately 10 -3 ) by using ionizing radiations or chemical mutagens. Radiation induced genetic variability in crop plants is a valuable resource from which plant breeder can select and combine different desired characteristics to produce better crop varieties. Crop improvement programmes at Bhabha Atomic Research Centre (BARC) envisage radiation based induced mutagenesis along with recombination breeding in country's important cereals (rice and wheat), oilseeds (groundnut, mustard, soybean and sunflower), grain legumes (blackgram, mungbean, pigeonpea and cowpea), banana and sugarcane

    Assess the evolution of cardiovascular lifestyle behaviors in hypercholesterolemic patients concomitantly with changes in their daily intake of phytosterol-supplemented yoghurt (Phyto-SY). Nationwide prospective observational study conducted in general practices across France and Spain. Each practitioner suggested lifestyle changes to five consecutive patients with hypercholesterolemia (whether or not they were taking hypocholesterolemic drugs) and recommended daily consumption of Phyto-SY. The study design involved an inclusion visit, a patient's self-monitoring assessment after 1 month, and a final visit after 4 months. Primary evaluation criterion: changes in dietary habits assessed by a standardized Nutritional Lifestyle score. Secondary criteria: changes in lipid profile, anthropometry (waist circumference) and lifestyle behavior. A total of 2376 hypercholesterolemic patients (of whom 54.8% were women) were included. The average age was 56.2 years old. The Nutritional Lifestyle score improved from 15.4 ± 5.4 to 8.7 ± 4.0 (p 30 min) increased from 59.3% to 78.3% (p < 0.0001). The overweight rate decreased from 22.8% to 17.5% (p < 0.0001) and waist circumference from 94.6 ± 13.3 cm to 93.0 ± 12.8 cm (p < 0.0001). Nutritional Lifestyles and other lifestyle markers' improvement were parallel to adherence to Phyto-SY adherence. Improvements in Nutritional Lifestyle scores, which included regular consumption of Phyto-SY over 4 months, was significantly linked to healthier lifestyles and to beneficial modifications in atherogenic lipid profiles, which reflected patient empowerment in a 'real life' context.

    The use of image-based dietary assessment methods shows promise for improving dietary self-report among children. The Technology Assisted Dietary Assessment (TADA) food record application is a self-administered food record specifically designed to address the burden and human error associated with conventional methods of dietary assessment. Users would take images of foods and beverages at all eating occasions using a mobile telephone or mobile device with an integrated camera [e.g. Apple iPhone, Apple iPod Touch (Apple Inc., Cupertino, CA, USA); Nexus One (Google, Mountain View, CA, USA)]. Once the images are taken, the images are transferred to a back-end server for automated analysis. The first step in this process is image analysis (i.e. segmentation, feature extraction and classification), which allows for automated food identification. Portion size estimation is also automated via segmentation and geometric shape template modeling. The results of the automated food identification and volume estimation can be indexed with the Food and Nutrient Database for Dietary Studies to provide a detailed diet analysis for use in epidemiological or intervention studies. Data collected during controlled feeding studies in a camp-like setting have allowed for formative evaluation and validation of the TADA food record application. This review summarises the system design and the evidence-based development of image-based methods for dietary assessment among children. © 2013 The Authors Journal of Human Nutrition and Dietetics © 2013 The British Dietetic Association Ltd.

    The use of mutation techniques for crop improvement in China has a long and well-established tradition of more than 50 years. As the result of intensive research in many institutes dealing with application of nuclear technologies more than 620 cultivars of 44 crop species have been released. Numerous mutant varieties have been grown on a large scale bringing significant economic impact, sustaining crop production and greatly contributing to increase of food production also in stress prone areas of the country. However, there is still missing information not only on the number of mutant varieties released in particular crop species but also on mutagens applied, selection approaches and on the use of mutants in cross breeding. Numerous Chinese scientists collected and systematized this information. Results of their work were often published in local scientific journals in the Chinese language and as such were unavailable to breeders from other countries. Having this in mind, we requested Dr. Liu Luxiang, the Director of the Department of Plant Mutation Breeding and Genetics, Institute for Application of Atomic Energy, Chinese Academy of Agricultural Sciences in Beijing to help us in finding as much information as possible on mutant varieties officially released in China. The data has been collected in close collaboration with his colleagues from various institutions all over the country and then evaluated, edited and prepared for publication by our team responsible for the FAO/IAEA Database of Officially Released Mutant Varieties. We would like to thank all Chinese colleagues who contributed to this list of Chinese mutant varieties. We hope that this publication will stimulate plant breeders in China to collect more information on released mutant varieties and especially on the use of mutated genes in cross breeding. (author)

    The prevalence of dietary supplement use varies largely among populations, and previous studies have indicated that it is high in the Danish population compared with other European countries. The diversity in supplement use across countries indicates that cultural and environmental factors could influence the use of dietary supplements. Only few studies investigating the use of dietary supplements have been conducted in the Danish population. The present cross-sectional study is based on 54,948 Danes, aged 50-64 years, who completed self-administrated questionnaires on diet, dietary supplements and lifestyle between 1993 and 1997. A health index including smoking, physical activity, alcohol and diet, and a metabolic risk index including waist circumference, urinary glucose and measured hypertension were constructed. Logistic regression was used to investigate these determinants in relation to the intake of dietary supplements. We found that 71 % of the participants were dietary supplement users; female sex, older age groups and higher educated participants were more likely to be users of any dietary supplements. One additional point in the health index was associated with 19, 16 and 9 % higher likelihood of being user of any, more common and less common supplements, respectively. In the metabolic risk index, one additional point was associated with 17 and 16 % lower likelihood of being user of any supplement and more common supplements, respectively. No significant association was found for less common supplement use. In conclusion, those with the healthiest lifestyle were more likely to use dietary supplements. Thus, lifestyle and dietary composition should be considered as confounders on supplement use and health outcomes.

    Full Text Available A 60-days feeding trial was conducted to determine the effect of dietary supplementation of Lonicera macranthoides leaf (LML on growth performance, meat quality, and free amino acid profiles in growing-finishing pigs. L. macranthoides leaves were harvested, air-dried and milled to powder. A total of 288 crossbred barrows (Large White × Landrace with an average initial BW of 54.0 ± 3.4 kg were randomly allocated to 3 treatment groups and fed either a basal diet or a diet supplemented with 0.5% or 1.0% LML powder. Results showed that diet supplemented with LML powder did not affect average daily feed intake (ADFI and feed: gain ratio (P > 0.05 in growing-finishing pigs. Moreover, diet supplemented with LML powder showed no significant effects on carcass traits (P > 0.05 including dressing percentage, backfat thickness and loin muscle area, and meat quality traits (P > 0.05 including meat color, intramuscular fat and cooking loss. However, diet supplemented with LML powder significantly improved free amino acid profiles in serum and longissimus thoracis muscle in growing-finishing pigs. Most importantly, dietary LML powder increased total free amino acids content (P < 0.001 and essential free amino acid content (P < 0.001 in longissimus thoracis muscle. These results indicate that LML has the potential to improve the nutritional value of meat through improving free amino acid profiles.

    Several educational intervention programs have been designed and developed to improve osteoporosis diagnosis and treatment. However, most of the prior studies focused on how educational intervention programs affected diagnosis and treatment of condition of osteoporosis. The purpose of this prospective and educational intervention study was to evaluate the changes in osteoporosis knowledge, osteoporosis self-efficacy, fall self-efficacy, physical exercise and changes in dietary pattern of calcium and vitamin D intake after osteoporosis education. From November 1, 2015 to August 31, 2016, 271 eligible candidates (who were over 50 years old and from 23 different community centers) were recruited through an announcement made by the public office, by two health care providers. The intervention involved an individualized education program to allow for differences in antecedent educational levels regarding several aspects of osteoporosis, including osteoporosis knowledge, osteoporosis self-efficacy, awareness of self-efficacy risk factors relating to an accidental fall and nutritional education (including the importance of sufficient calcium and vitamin D intake). The researchers revisited the community centers three months after the initial visit. Of the 271 potential participants, 199 (73.4%; 43 men and 156 women) completed the education program and the second questionnaire. After education intervention, parameters including osteoporosis knowledge, osteoporosis self-efficacy and fall self-efficacy were improved (P vitamin D intake below recommended cut-offs, inadequate dietary calcium and vitamin D intake were decreased (P vitamin D intake.

    Dietary triggers are commonly reported by patients with a variety of headaches, particularly those with migraines. The presence of any specific dietary trigger in migraine patients varies from 10 to 64 % depending on study population and methodology. Some foods trigger headache within an hour while others develop within 12 h post ingestion. Alcohol (especially red wine and beer), chocolate, caffeine, dairy products such as aged cheese, food preservatives with nitrates and nitrites, monosodium glutamate (MSG), and artificial sweeteners such as aspartame have all been studied as migraine triggers in the past. This review focuses the evidence linking these compounds to headache and examines the prevalence of these triggers from prior population-based studies. Recent literature surrounding headache related to fasting and weight loss as well as elimination diets based on serum food antibody testing will also be summarized to help physicians recommend low-risk, non-pharmacological adjunctive therapies for patients with debilitating headaches.

    Abstract Objective To investigate whether improving adherence to healthy dietary patterns interacts with the genetic predisposition to obesity in relation to long term changes in body mass index and body weight. Design Prospective cohort study. Setting Health professionals in the United States. Participants 8828 women from the Nurses’ Health Study and 5218 men from the Health Professionals Follow-up Study. Exposure Genetic predisposition score was calculated on the basis of 77 variants associated with body mass index. Dietary patterns were assessed by the Alternate Healthy Eating Index 2010 (AHEI-2010), Dietary Approach to Stop Hypertension (DASH), and Alternate Mediterranean Diet (AMED). Main outcome measures Five repeated measurements of four year changes in body mass index and body weight over follow-up (1986 to 2006). Results During a 20 year follow-up, genetic association with change in body mass index was significantly attenuated with increasing adherence to the AHEI-2010 in the Nurses’ Health Study (P=0.001 for interaction) and Health Professionals Follow-up Study (P=0.005 for interaction). In the combined cohorts, four year changes in body mass index per 10 risk allele increment were 0.07 (SE 0.02) among participants with decreased AHEI-2010 score and −0.01 (0.02) among those with increased AHEI-2010 score, corresponding to 0.16 (0.05) kg versus −0.02 (0.05) kg weight change every four years (Pdietary patterns could attenuate the genetic association with weight gain. Moreover, the beneficial effect of improved diet quality on weight management was particularly pronounced in people at high genetic risk for obesity. PMID:29321156

    This article describes adherence to a low-fat dietary pattern (less than 20% energy from fat, five or more fruit/vegetable and six or more grain servings daily) in Years 1 and 5 of the Women's Health Initiative Dietary Modification Trial, which was designed to examine the effects of a low-fat dietary pattern on risk of breast and colorectal cancers and other chronic diseases in postmenopausal women. Participants were randomly assigned to a low-fat dietary intervention arm (40%, n=19,542) or a usual diet control arm (60%, n=29,294). Women in the intervention arm completed 18 group sessions during the first year, followed by quarterly annual maintenance sessions. Adherence was assessed as control minus intervention (C-I) group differences in percent total energy from fat as estimated by a food frequency questionnaire. Based on these self-reported dietary data, mean C-I was 10.9 percentage points of energy from fat at Year 1, decreasing to 9.0 at Year 5. Factors associated with poorer adherence were being older, being African American or Hispanic (compared with white), having low income, and being obese. Group session attendance was strongly associated with better dietary adherence. There are many limitations of self-reported dietary data, particularly related to social desirability and intervention-associated bias. Nonetheless, these data indicate that long-term dietary change was achieved in this clinical trial setting and reinforce the potential of the ongoing trial to answer questions of public health importance.

    Little is known about the feasibility of online education in improving communication and documentation of dietary supplements (DS) among clinicians. This prospective educational study included clinicians at an urban teaching hospital. The curriculum included video streams, didactics, and interactive case presentations to discuss (1) DS safety and effectiveness, (2) cultural competency, (3) managing DS in a hospital setting, and (4) DS adverse events. Participants were surveyed, at baseline and after training, about DS knowledge, confidence, communication, and documentation practices. Thirty-nine of 61 (64%) recruited clinicians completed all four patient cases and post-tests. Most (82%) were women and 59% were physicians. The mean DS knowledge test score increased after the curriculum (p online curriculum is an effective tool for presenting DS education to clinicians with the goal of improving clinicians' knowledge, confidence, and documentation practices about DS.

    We say that a group G acts infinitely transitively on a set X if for every m element of N the induced diagonal action of G is transitive on the cartesian mth power X m backslash Δ with the diagonals removed. We describe three classes of affine algebraic varieties such that their automorphism groups act infinitely transitively on their smooth loci. The first class consists of normal affine cones over flag varieties, the second of nondegenerate affine toric varieties, and the third of iterated suspensions over affine varieties with infinitely transitive automorphism groups.

    Dietary Reference Values (DRVs) for vitamin D have a key role in the prevention of vitamin D deficiency. However, despite adopting similar risk assessment protocols, estimates from authoritative agencies over the last 6 years have been diverse. This may have arisen from diverse approaches to data analysis. Modelling strategies for pooling of individual subject data from cognate vitamin D randomized controlled trials (RCTs) are likely to provide the most appropriate DRV estimates. Thus, the objective of the present work was to undertake the first-ever individual participant data (IPD)-level meta-regression, which is increasingly recognized as best practice, from seven winter-based RCTs (with 882 participants ranging in age from 4 to 90 years) of the vitamin D intake–serum 25-hydroxyvitamin D (25(OH)D) dose-response. Our IPD-derived estimates of vitamin D intakes required to maintain 97.5% of 25(OH)D concentrations >25, 30, and 50 nmol/L across the population are 10, 13, and 26 µg/day, respectively. In contrast, standard meta-regression analyses with aggregate data (as used by several agencies in recent years) from the same RCTs estimated that a vitamin D intake requirement of 14 µg/day would maintain 97.5% of 25(OH)D >50 nmol/L. These first IPD-derived estimates offer improved dietary recommendations for vitamin D because the underpinning modeling captures the between-person variability in response of serum 25(OH)D to vitamin D intake.

Modelling strategies for pooling of individual subject data from cognate vitamin D randomized controlled trials (RCTs are likely to provide the most appropriate DRV estimates. Thus, the objective of the present work was to undertake the first-ever individual participant data (IPD-level meta-regression, which is increasingly recognized as best practice, from seven winter-based RCTs (with 882 participants ranging in age from 4 to 90 years of the vitamin D intake–serum 25-hydroxyvitamin D (25(OHD dose-response. Our IPD-derived estimates of vitamin D intakes required to maintain 97.5% of 25(OHD concentrations >25, 30, and 50 nmol/L across the population are 10, 13, and 26 µg/day, respectively. In contrast, standard meta-regression analyses with aggregate data (as used by several agencies in recent years from the same RCTs estimated that a vitamin D intake requirement of 14 µg/day would maintain 97.5% of 25(OHD >50 nmol/L. These first IPD-derived estimates offer improved dietary recommendations for vitamin D because the underpinning modeling captures the between-person variability in response of serum 25(OHD to vitamin D intake.

    Meat is an important source of all essential nutritional components of our daily diet as it content most of the essential amino acids, fatty acids, vitamins, and minerals which are lack in plant based food, but it is devoid of dietary fiber, which is very essential component for normal physiological/biochemical process. During meat products processing, its functional values can be improved by supplementation of dietary fiber rich vegetative substances like cereal and pulse flour, vegetable and fruits pulp, etc. by this process, a significant proportion of required daily allowance of dietary fiber can be fulfilled for the frequent meat consumers. The consumption of meat products fortified with of dietary fiber can lead to the prevention of diseases like coronary heart disease, diabetes, irritable bowel disease, obesity, etc. On the other hand, the dietary fiber can effectively be incorporated in the processed meat products as binders, extender, and filler, they can significantly replace the unhealthy fat components from the products; increase acceptability by improving nutritional components, pH, water-holding capacity, emulsion stability, shear press value, sensory characters, etc. of finished products. Addition of dietary fiber in the meat products can increase the cooking yield therefore the economic gain as well.

    The cost and dietary choices required to fulfil nutrient recommendations defined nationally, need investigation, particularly for disadvantaged populations. We used optimisation modelling to examine the dietary change required to achieve nutrient requirements at minimum cost for an Aboriginal population in remote Australia, using where possible minimally-processed whole foods. A twelve month cross-section of population-level purchased food, food price and nutrient content data was used as the baseline. Relative amounts from 34 food group categories were varied to achieve specific energy and nutrient density goals at minimum cost while meeting model constraints intended to minimise deviation from the purchased diet. Simultaneous achievement of all nutrient goals was not feasible. The two most successful models (A & B) met all nutrient targets except sodium (146.2% and 148.9% of the respective target) and saturated fat (12.0% and 11.7% of energy). Model A was achieved with 3.2% lower cost than the baseline diet (which cost approximately AUD$13.01/person/day) and Model B at 7.8% lower cost but with a reduction in energy of 4.4%. Both models required very large reductions in sugar sweetened beverages (-90%) and refined cereals (-90%) and an approximate four-fold increase in vegetables, fruit, dairy foods, eggs, fish and seafood, and wholegrain cereals. This modelling approach suggested population level dietary recommendations at minimal cost based on the baseline purchased diet. Large shifts in diet in remote Aboriginal Australian populations are needed to achieve national nutrient targets. The modeling approach used was not able to meet all nutrient targets at less than current food expenditure.

    Full Text Available Obesity has been recognized as one of the most important risk factors for a variety of chronic diseases, such as diabetes, hypertension/cardiovascular diseases, steatosis/hepatitis, and cancer. Keishibukuryogan (KBG, Gui Zhi Fu Ling Wan in Chinese is a traditional Chinese/Japanese (Kampo medicine that has been known to improve blood circulation and is also known for its anti-inflammatory or scavenging effect. In this study, we evaluated the effect of KBG in two distinct rodent models of obesity driven by either a genetic (SHR/NDmcr-cp rat model or dietary (high-fat diet-induced mouse obesity model mechanism. Although there was no significant effect on the body composition in either the SHR rat or the DIO mouse models, KBG treatment significantly decreased the serum level of leptin and liver TG level in the DIO mouse, but not in the SHR rat model. Furthermore, a lower fat deposition in liver and a smaller size of adipocytes in white adipose tissue were observed in the DIO mice treated with KBG. Importantly, we further found downregulation of genes involved in lipid metabolism in the KBG-treated liver, along with decreased liver TG and cholesterol level. Our present data experimentally support in fact that KBG can be an attractive Kampo medicine to improve obese status through a regulation of systemic leptin level and/or lipid metabolism.

    Dietary supplements intake has grown in the last years because of their potential health benefits. This supplementation is very common among athletes, elderly population and consumers that want to increase the total daily nutrient intake. Consequently, elemental composition evaluation in these supplements is of great interest due to its increasingly high consumption and the brand variety offered in the market. This study aimed to evaluate the elemental composition in three types of dietary supplements acquired in a pharmacy and drugstore in Sao Paulo city. Concentrations of As, Br, Ca, Co, Cr, Cu, Fe, K, La, Na, Sb, Sc, Se and Zn were determined in these supplements by applying neutron activation analysis (NAA) followed by a gamma ray spectrometry. from the concentrations obtained in the dietary supplement analyses, the data obtained were compared to the values presented on the product label. These comparisons indicated in general, a good agreement of the data obtained and the values of the product label depending on the supplement. From the results obtained it can be concluded that NAA is an important tool for the analysis of this type of products due to its reliability of results and its multielemental character. (author)

    We evaluated the effectiveness of a community-based healthy lifestyle intervention in improving dietary behaviors of pregnant Latinas from 2004 to 2006 in Detroit, Michigan. The 11-week, culturally tailored, Spanish-language Healthy Mothers on the Move (MOMs) intervention offered home visits, group classes, related activities, and social support from trained community health workers (CHWs) and peers. Dietary behaviors were measured by food frequency questionnaire. Linear mixed models estimated pre- and post-intervention changes, within and between MOMs intervention and minimal intervention (MI) groups. MOMs (n = 139) and MI (n = 139) participants had similar baseline characteristics and dietary intake. Post-intervention, MOMs participants showed significant improvement in all dietary behaviors, except fruit and fiber consumption. Compared with MI participants, MOMs participants had significantly decreased consumption of added sugar (P = .05), total fat (P < .05), saturated fat (P < .01), percentage of daily calories from saturated fat (P < .001), solid fats and added sugars (P < .001), and had increased vegetable consumption (P < .001). Their increase in fiber consumption (P < .05) was significant relative to MI participants' decrease in fiber intake. We confirmed the hypothesis that a community-planned, CHW-led healthy lifestyle intervention could improve dietary behaviors of low-income Latina women during pregnancy.

    The current study investigated the effects of dietary Aloe vera on plasma lipid profile status, antioxidant, and hepatoprotective enzyme activities of GIFT-tilapia juveniles under Streptococcus iniae challenge. Five dietary groups were designed including a control and 100 % Aloe powder incorporated into a tilapia feed at 0.5, 1, 2, and 4 %/kg feed, which were administered for 8 weeks. Fish fed dietary Aloe at 4 %/kg feed significantly reduced in total cholesterol, while triacylglycerol reduced (P Aloe/kg feed compared to unsupplemented ones. High-density lipoprotein was significantly elevated in fish fed 0.5 and 1 % Aloe/kg feed compared to unsupplemented ones, and no significant changes (P > 0.05) were noted in low-density lipoprotein among test groups. Furthermore, high activities of superoxide dismutase, catalase, and glutathione peroxide in liver tissues were observed in Aloe-supplemented fish compared to unsupplemented ones, before and after S. iniae challenge (7.7 × 10(6) CFU cells/mL). Variations were also noted in malondialdehyde activity throughout the trial, but no significant difference (P > 0.05) was observed between groups. Meanwhile, Aloe-supplemented fish reduced serum aspartate and alanine aminotransferase (AST and ALT) activities before and after challenge. Based on the second-order polynomial regression analysis, dietary Aloe inclusion levels less than or equal to 1.88, 1.86, and 2.79 %/kg feed were determined to be suitable in improving plasma lipid profile status, antioxidant, and hepatoprotective enzyme activities in GIFT-tilapia in this study, respectively. Thus, A. vera extracts may be recommended as a tilapia feed supplement to enhance fish antioxidant and hepatoprotective capacities, especially during disease outbreaks.

    Full Text Available Adolescents in Australia have a poor dietary intake, leading to large numbers of them being at risk for inadequate intake of micronutrients, and excessive intake of less healthful dietary components. This study examined dietary intakes at multiple eating occasions to identify opportunities for more targeted recommendations and strategies to improve dietary intakes among adolescents. Data from the first 24-h recall of 14–18 years old in the 2011–2012 National Nutrition and Physical Activity Survey were analysed (n = 772. Participant-defined eating occasions were classified as breakfast, lunch, dinner or other eating occasions combined. The mean percent contribution to the total day intake of top shortfall nutrients (calcium, magnesium, vitamin A, iron, discretionary calories, saturated fat, free sugars and sodium, as well as nutrient density, the foods consumed and the percent of consumers at each eating occasion, were calculated. Breakfast had the lowest prevalence of consumers (81%, contributed the least to total daily energy (14.6% and almost a quarter of daily calcium and iron. Other eating occasions combined contributed 47.5% of free sugars and were top contributors of daily calcium (34.6% and magnesium (31.7%. Discretionary foods contributed 32.4% of the energy at lunch, and the sodium content at lunch was 415 mg/1000 kJ. Key opportunities identified for adolescents were to increase breakfast consumption, given the high nutrient densities of breakfasts consumed; improve overall lunch quality, particularly the sodium content; promote the intake of milk, fruit and a variety of vegetables at both lunch and dinner; maintain healthful choices at in-between meal eating occasions while focusing on decreasing the intake of discretionary foods.

    The multiple dietary restrictions recommended to hemodialysis patients may be difficult to achieve and, at the same time, may result in nutritional deficiencies rendering a poor dietary quality. We here assess the dietary quality and adherence to renal-specific guideline recommendations among hemodialysis patients from a single center in Canary Islands, Spain. Cross-sectional study, including 91 patients undergoing maintenance hemodialysis. Clinical data and 3-day dietary records were collected. We compared patient's reported nutrients intake with guideline recommendations. We also evaluated their alignment with current American Heart Association dietary guidelines for cardiovascular prevention. Seventy-seven percent and 50% of patients consumed less than the recommended daily energy and protein, respectively. Although half of the patients met the recommendations for dietary fat intake, this was accounted by an excess of saturated fat in 92% of them. Only 22% consumed sufficient fiber. A very small proportion of patients (less than 50%) met the requirements for vitamins and other micronutrients. Insufficient dietary intake was observed in most patients for all vitamins except for cobalamin. Similarly, inadequate dietary intake was observed for many minerals, by both excess (phosphorus, calcium, sodium, and potassium) and defect (magnesium). Most patients met the recommendations for iron and zinc in their diets. A large proportion of hemodialysis patients at our center did not meet current renal-specific dietary recommendations. The quality of the diet was considered poor and proatherogenic according to American Heart Association guidelines. Copyright © 2016 National Kidney Foundation, Inc. Published by Elsevier Inc.

    Chia (Salvia hispanica L.) plant is native from southern Mexico and northern Guatemala. Their seeds are a rich source of bioactive compounds which protect consumers against chronic diseases. Germination improves functionality of the seeds due to the increase in the bioactive compounds and associated antioxidant activity. The purpose of this study was to obtain functional flour from germinated chia seeds under optimized conditions with increased antioxidant activity, phenolic compounds, GABA, essential amino acids, and dietary fiber with respect to un-germinated chia seeds. The effect of germination temperature and time (GT = 20-35 °C, Gt = 10-300 h) on protein, lipid, and total phenolic contents (PC, LC, TPC, respectively), and antioxidant activity (AoxA) was analyzed by response surface methodology as optimization tool. Chia seeds were germinated inside plastic trays with absorbent paper moisturized with 50 mL of 100 ppm sodium hypochlorite dissolution. The sprouts were dried (50 °C/8 h) and ground to obtain germinated chia flours (GCF). The prediction models developed for PC, LC, TPC, and AoxA showed high coefficients of determination, demonstrating their adequacy to explain the variations in experimental data. The highest values of PC, LC, TPC, and AoxA were obtained at two different optimal conditions (GT = 21 °C/Gt = 157 h; GT = 33 °C/Gt = 126 h). Optimized germinated chia flours (OGCF) had higher PC, TPC, AoxA, GABA, essential amino acids, calculated protein efficiency ratio (C-PER), and total dietary fiber (TDF) than un-germinated chia seed flour. The OGCF could be utilized as a natural source of proteins, dietary fiber, GABA, and antioxidants in the development of new functional beverages and foods.

    Improving infant and young child feeding practices is critical for improving growth and reducing child mortality and morbidity. This paper aims to compare predictors of minimum dietary diversity, an important indicator of adequate complementary feeding practices, in Bangladesh in 2011 and 2014. The 2011 and 2014 Bangladesh Demographic and Health Survey were used to examine predictors of minimum dietary diversity among 6-23 months. An additional analysis was conducted for the 18-23-month group, because a significant increase in meeting minimum dietary diversity recommendations was seen in this age group only. Factors found to be associated with practices were compared across time points. In 2011, minimum dietary diversity was 23.8% and increased to 28.8% in 2014. Among children 18-23 months, in 2011, minimum dietary diversity was 32.5% and increased to 42.8% in 2014. Among all children, wealth, education, exposure to media, and antenatal care were significant predictors of dietary diversity. In the 18-23-month age group, significant predictors in 2011 were wealth and decision making. In 2014, significant predictors were education and exposure to media. Demographic trends indicated a significant increase in education and exposure to media between 2011 and 2014. As these were significant for minimum dietary diversity in 2014 overall and for 18-23 months, they might be important targets of future interventions, specifically utilizing media channels and tailoring special strategies for women with low education and limited exposure to media. © 2018 John Wiley & Sons Ltd.

    This study was conducted to observe recent changes in adolescents' dietary behavior and indirectly evaluate the effects of the government's nutritional policies in Korea. We analyzed the secular trends in seven dietary behaviors using the Korea Youth Risk Behavior Web-based Survey data from 2005 to 2009. Through literature review, we included the policies implemented for the improvement of adolescents'dietary behaviors during the same periods. The significant linear trends were observed in all dietary behaviors (ppolicies were implemented including 'Ban on carbonated-beverages in school', 'Green Food Zone', etc. Despite confirmed evidence of their effects, the policies on individual behavior such as nutrition education didn't influence the prevalence of dietary behaviors because they were conducted to too limited persons. Policies on the school environmental improvement, such as ban on carbonated beverage in school, were more effective because they decreased the exposure of undesirable food environment. However, for effect of Green Food Zone improving community environment we couldn't come to a conclusion because of too short period after full implementation. Among government nutrition policies conducted from 2005 to 2009, those on environmental improvement, especially in school, were more effective than those on individual behavior. Therefore, the development and implement of policies on school environmental improvement are needed in Korea.

    The influence of acute and recurrent gamma irradiation was investigated on the quantitative characters of Dukat, Paloma, BR 52, Ujmajor early and Marro pea varieties. All five varieties were irradiated with 25, 50, 75 and 100 Gy of gamma rays. The influence of recurrent irradiation was investigated in two and three subsequent generations. Varietal differences in radiation sensitivity were observed. The yield components of different varieties changed under similar dose conditions. The Dukat variety was found to be most sensitive to acute irradiation, so the quantitative characters of Dukat may be improved by using this method. Recurrent irradiation in two subsequent generations was succesful in the Paloma variety while treating three subsequent generations proved to be less succesful in improving yield components than in two generations.

    Rice bean ( Vigna umbellata ) is grown in South and Southeast Asia, and the bean has gained importance due to its nutritional strength in terms of dietary fiber, quality protein and minerals. In current study, the nutritional and functional components, cooking and thermo-gravimetric properties of eleven rice bean varieties from NE India were investigated. Results revealed that the major nutrients among the varieties ranged as follows: 54.21-60.49% carbohydrates, 15.64-21.60% protein, 1.22-2.3% fat, 5.53-6.56% crude fibre, 3.34-3.8% ash; while the functional, anti-nutritional factors and mineral were present as 1189.32-1645.8 mg gallic acid equivalent (GAE)/100 g polyphenols, 205.38-432.14 mg/100 g phytic acid, 23.14-34.12 mg/100 g oxalate, 690.7-1589.5 mg/100 g saponins, 49.90-158.17 μg/100 g hydrocyanide, 111.51-168 calcium, 5.50-10.44 zinc, 3.72-8.37 iron. Principal component analysis revealed that varieties with higher calcium, iron and ash content had lower cooking time, swelling ratio, and cooked grain hardness. It is also revealed that varieties with higher weight loss at sixth stage in thermogravimetric graph had lower carbohydrate and higher protein content. Nagadal variety had higher fat, potassium, magnesium, calcium, sodium, iron, copper and chromium content and better cooking quality as compared to the other varieties. The study revealed that Nagadal variety was superior to other varieties with respect to mineral content, cooking and thermal properties and hence have better potential in the development of value added products.

    The area of dietary assessment is becoming increasingly important as obesity rates soar, but valid measurement of the food intake in free-living persons is extraordinarily challenging. Traditional paper-based dietary assessment methods have limitations due to bias, user burden and cost, and therefore improved methods are needed to address important hypotheses related to diet and health. In this paper, we will describe the progress of our mobile Diet Data Recorder System (DDRS), where an electronic device is used for objective measurement on dietary intake in real time and at moderate cost. The DDRS consists of (1) a mobile device that integrates a smartphone and an integrated laser package, (2) software on the smartphone for data collection and laser control, (3) an algorithm to process acquired data for food volume estimation, which is the largest source of error in calculating dietary intake, and (4) database and interface for data storage and management. The estimated food volume, together with direct entries of food questionnaires and voice recordings, could provide dietitians and nutritional epidemiologists with more complete food description and more accurate food portion sizes. In this paper, we will describe the system design of DDRS and initial results of dietary assessment.

    Acculturation, the subsequent changes that occur in one culture after continuous first hand contact with another culture, impacts the dietary habits and health risks of individuals. This study examines the acculturation, dietary habits and anthropometric measurements in a sample of 210 first generation Filipino American immigrants in New Jersey (NJ). Acculturation was measured using the Short Acculturation Scale for Filipino Americans (ASASFA). Dietary acculturation was measured using the Dietary Acculturation Questionnaire for Filipino Americans (DAQFA) and dietary intake was determined using the Block's Brief Food Frequency Questionnaire (BFFQ). Anthropometric measurements were obtained including weight, height and waist circumference. Acculturation had a significant negative relationship with Filipino Dietary acculturation. Western dietary acculturation was significantly correlated with caloric intake (r(208) = 0.193, p Filipino dietary acculturation, dietary intake and anthropometric measurements. The results showed that Filipino American immigrants have increased risks including increased BMI, waist circumference and increased fat intake. Over all, this research highlighted some dietary changes and their effects on dietary intake and health status.

    In the Laboratory of Genetics and Improvement of the National Institute of Agricultural Sciences was developed a Program of Genetic Improvement using Biotechnical and Nuclear Techniques in order to obtain new rice varieties of high yield potential under drought stress condition. For them different explants types were used starting from seeds of the Cuban variety of rice Amistad 82 irradiated with protons in dose of 10, 20, 30, 40, 50, 60, 70, 80, 90 and 100 Gy. The explants were cultivated in vitro in order to obtaining callus and later plant regenerate. The plant selected in vitro was multiplied being carried out several selection cycles under field conditions. A remarkable stimulation was observed from the regeneration of plants when using dose of 20 Gy and it was possible to select 4 promising lines that differ of the donor as for cycle, architecture of the plant and tolerance to drought. Tjis result demonstrates the potentialities of this radiation source for obtaining of new rice varieties

    Full Text Available Bread wheat (Triticum aestivum L. is an important cereal in human consumption. In recent years, there has been a growing interest in ancient wheat varieties. The latter represent an important source of germplasm, characterised by a broader genetic base and, therefore, a potential source of biodiversity. The objective of the study was to ascertain the optimal balance between the presence of secondary metabolites having beneficial effects on health and technological features that ensure successful baking quality. The experimental trial was performed in 2011-2012 on three organic farms located in three different areas within the province of Siena (Tuscany. In each location, an overall evaluation of the commercial, rheological and functional properties of five ancient Tuscan bread wheat varieties (Andriolo, Frassineto, Gentil rosso, Inallettabile 96, Verna as compared with a commercial modern variety (Palesio was carried out. The ancient varieties were compared both singularly (pure and in combination (mixtures of two varieties in equal proportion, respectively. Biometric and productive parameters were detected for each plot (32 plots in each farm. Macro- and trace elements, polyphenols, flavonoids and antioxidant activity (antiradical power, ARP were similarly determined on representative whole grain samples. Rheological analysis was carried out on flour samples. The multivariate statistical analysis using principal components analysis was performed on all variables analysed. The results showed a significant environment effect on the different parameters measured and did not reveal significant improvements in the variables measured when varieties were cultivated in mixtures. However, the study did reveal various interesting trends that are warranting of further investigation. The most interesting effect from a nutritional and functional point of view is the relationship between ARP, rheological properties, protein content and gluten content. These

    Dietary restriction (DR) improves health, delays tissue aging, and elongates survival in flies and worms. However, studies on laboratory mice and nonhuman primates revealed ambiguous effects of DR on lifespan despite improvements in health parameters. In this study, we analyzed consequences of adult-onset DR (24 h to 1 yr) on hematopoietic stem cell (HSC) function. DR ameliorated HSC aging phenotypes, such as the increase in number of HSCs and the skewing toward myeloid-biased HSCs during aging. Furthermore, DR increased HSC quiescence and improved the maintenance of the repopulation capacity of HSCs during aging. In contrast to these beneficial effects, DR strongly impaired HSC differentiation into lymphoid lineages and particularly inhibited the proliferation of lymphoid progenitors, resulting in decreased production of peripheral B lymphocytes and impaired immune function. The study shows that DR-dependent suppression of growth factors and interleukins mediates these divergent effects caused by DR. Supplementation of insulin-like growth factor 1 partially reverted the DR-induced quiescence of HSCs, whereas IL-6/IL-7 substitutions rescued the impairment of B lymphopoiesis exposed to DR. Together, these findings delineate positive and negative effects of long-term DR on HSC functionality involving distinct stress and growth signaling pathways. PMID:26951333

    To investigate whether improving adherence to healthy dietary patterns interacts with the genetic predisposition to obesity in relation to long term changes in body mass index and body weight. Prospective cohort study. Health professionals in the United States. 8828 women from the Nurses' Health Study and 5218 men from the Health Professionals Follow-up Study. Genetic predisposition score was calculated on the basis of 77 variants associated with body mass index. Dietary patterns were assessed by the Alternate Healthy Eating Index 2010 (AHEI-2010), Dietary Approach to Stop Hypertension (DASH), and Alternate Mediterranean Diet (AMED). Five repeated measurements of four year changes in body mass index and body weight over follow-up (1986 to 2006). During a 20 year follow-up, genetic association with change in body mass index was significantly attenuated with increasing adherence to the AHEI-2010 in the Nurses' Health Study (P=0.001 for interaction) and Health Professionals Follow-up Study (P=0.005 for interaction). In the combined cohorts, four year changes in body mass index per 10 risk allele increment were 0.07 (SE 0.02) among participants with decreased AHEI-2010 score and -0.01 (0.02) among those with increased AHEI-2010 score, corresponding to 0.16 (0.05) kg versus -0.02 (0.05) kg weight change every four years (Pdietary patterns could attenuate the genetic association with weight gain. Moreover, the beneficial effect of improved diet quality on weight management was particularly pronounced in people at high genetic risk for obesity. Published by the BMJ Publishing Group Limited.

    (i) To identify determinants of participation in the 'Healthy School Canteen Program', a programme that encourages schools to set up their canteen in a way that promotes healthy dietary behaviour. (ii) To compare food supply and actions between participating and non-participating schools. (iii) To investigate what reasons schools have to increase attention for nutrition in the curriculum. A cross-sectional study based on information from questionnaires performed in 2010/2011. All secondary schools (age group 12-18 years) in the Netherlands (n 1145). Response was 33 % (n 375). Analyses included all schools with a canteen in which food is offered (28 %, n 325). None of the investigated determinants was associated with participation. Participating schools offered significantly (P schools. However, there was no difference in the number of less healthy products offered (e.g. candy bars, cakes and regular soft drinks). Participating schools reported more often that they took actions to improve dietary behaviour and more often had a policy on nutrition. Participating schools more often increased attention for nutrition in the curriculum in recent years than non-participating schools (57 % v. 43 %, P = 0·01). Reported reasons were similar and included media attention, eating behaviour of students and 'overweight'. Schools that participate in the programme seemed to offer more healthy products in their canteens and took more actions to improve dietary behaviour than non-participating schools. However, at all schools less healthy foods were also available.

    Despite the well-documented importance of nutrition in optimizing performance and health, the dietary intake of soccer players has attracted little attention. We aimed to assess the pre-season dietary intake of professional soccer players and its adequacy in macro and micronutrients. The pre-season dietary intake of 19 male athletes was assessed using a semi-structured 3-day food record. To determine dietary adequacy and excess, energy and macronutrient intake were compared with the Brazilian dietary reference values for athletes, and micronutrients were compared with the Estimated Average Requirement - EAR (minimum recommendation) and Tolerable Upper Intake Level - UL (maximum recommendation). Mean daily energy intake (40.74±12.81 kcal/kg) was adequate. However, there was a low carbohydrate intake (5.44±1.86 g/kg/day) and a high amount of protein and fat (1.91±0.75 and 1.27±0.50 g/kg/day, respectively). Sodium intake (3141.77±939.76 mg/day) was higher than UL (2300 mg/day), while the majority of players showed daily intake of vitamin A (74%), vitamin D (100%), folate (58%), calcium and magnesium (68%) below the EAR (625, 10 and 320 µg/day, 800 and 330 mg/day, respectively). The dietary intake of professional soccer players was adequate in energy, but inadequate in macro and micronutrients, which suggests the need to improve nutritional practices to sustain the physical demands of soccer during pre-season.

    This review focuses on dietary intake and dietary supplement use among the U.S. population age 1-74 based on four National Health and Nutrition Examination Surveys conducted in 1971-74, 1976-80, 1988-94, and 1999-2000. Secular trends in intake of energy, macronutrients, cholesterol, sodium, calcium, iron, folate, zinc, vitamins A and C, fruits, vegetables, and grain products are summarized. During the 30-year period, mean energy intake increased among adults, and changed little among children age 1-19, except for an increase among adolescent females. Factors contributing to increases in energy intake include increases in the percentage of the population eating away from home (particularly at fast-food restaurants), larger portion sizes of foods and beverages, increased consumption of sweetened beverages, changes in snacking habits, and improved dietary methodology. Dietary supplement use increased among adult men and women, decreased among children age 1-5, and was stable for children age 6-11 and adolescents.

    Full Text Available Lactobacillus rhamnosus GG (LGG has been regarded as a safe probiotic strain. The aim of this study was to investigate whether dietary LGG supplementation could alleviate diarrhea via improving jejunal mucosal barrier function in the weaned piglets challenged by RV, and further analyze the potential roles for apoptosis of jejunal mucosal cells and intestinal microbiota. A total of 24 crossbred barrows weaned at 21 d of age were assigned randomly to 1 of 2 diets: the basal diet and LGG supplementing diet. On day 11, all pigs were orally infused RV or the sterile essential medium. RV infusion increased the diarrhea rate, increased the RV-Ab, NSP4 and IL-2 concentrations and the Bax mRNA levels of jejunal mucosa (P<0.05, decreased the villus height, villus height: crypt depth, the sIgA, IL-4 and mucin 1 concentrations and the ZO-1, occludin and Bcl-2 mRNA levels of jejunal mucosa (P<0.05, and affected the microbiota of ileum and cecum (P<0.05 in the weaned pigs. Dietary LGG supplementation increased the villus height and villus height: crypt depth, the sIgA, IL-4, mucin 1 and mucin 2 concentrations, and the ZO-1, occludin and Bcl-2 mRNA levels of the jejunal mucosa (P<0.05 reduced the Bax mRNA levels of the jejunal mucosa (P<0.05 in weaned pigs. Furthermore, dietary LGG supplementation alleviated the increase of diarrhea rate in the weaned pigs challenged by RV (P<0.05, and relieve the effect of RV infection on the villus height, crypt depth and the villus height: crypt depth of the jejunal mucosa (P<0.05, the NSP4, sIgA, IL-2, IL-4, mucin 1 and mucin 2 concentrations of jejunal mucosa (P<0.05, the ZO-1, occludin, Bax and Bcl-2 mRNA levels of the jejunal mucosa (P<0.05, and the microbiota of ileum and cecum (P<0.05 in the weaned pigs challenged by RV. These results suggest that supplementing LGG in diets alleviated the diarrhea of weaned piglets challenged by RV via inhibiting the virus multiplication and improving the jejunal mucosal barrier

    Objective Non-alcoholic steatohepatitis (NASH) is the outcome of interactions between overnutrition, energy metabolism, and adipose function. Obeticholic acid (OCA) improves steatosis in patients, but for unknown reason does not resolve NASH pathology. We therefore investigated OCA effects in Wt mice which develop obesity with atherogenic dietary feeding, and appetite-dysregulated, Alms1 mutant foz/foz mice fed the same diet which develop metabolic obesity and diabetes. Methods OCA (1mg/kg) was administered orally to female foz/foz mice and Wt littermates from weaning until 28 weeks. We studied adipose indices, glucose tolerance and fatty liver pathology. Experiments were repeated with OCA 10mg/kg. Results OCA reduced body weight and hepatic lipids and improved glucose disposal only in Wt mice. OCA limited Wt adipose expansion, altered morphometry in favour of small adipocytes, enhanced expression of genes indicating adipose browning, and reduced crown-like structure (CLS) number in visceral adipose. foz/foz mice showed more CLSs in all compartments; OCA failed to alter adipose morphometry, browning, inflammation, or improve NASH severity, even at 10mg/kg. Conclusion OCA improves adipose indices, glucose tolerance and steatosis in milder metabolic phenotype, but fails to improve these factors in morbidly obese diabetic mice. These results help explain OCA’s limited efficacy to reverse human NASH. PMID:27804232

    Background: Dietary supplements are used by one-third of children. We examined motivations for supplement use in children, the types of products used by motivations, and the role of physicians and health care practitioners in guiding choices about supplements. Methods: We examined motivations for dietary supplement use reported for children (from birth to 19 y of age; n = 8,245) using the National Health and Nutrition Examination Survey 2007–2010. Results: Dietary supplements were used by 31% of children; many different reasons were given as follows: to “improve overall health” (41%), to “maintain health” (37%), for “supplementing the diet” (23%), to “prevent health problems” (20%), and to “boost immunity” (14%). Most children (~90%) who use dietary supplements use a multivitamin–mineral or multivitamin product. Supplement users tend to be non-Hispanic white, have higher family incomes, report more physical activity, and have health insurance. Only a small group of supplements used by children (15%) were based on the recommendation of a physician or other health care provider. Conclusion: Most supplements used by children are not under the recommendation of a health care provider. The most common reasons for use of supplements in children are for health promotion, yet little scientific data support this notion in nutrient-replete children. PMID:24002333

    The importance of the diet in modulating mental health is uncovering as many dietary factors have been described to alter brain chemistry. Brain maturation may not complete until the age of 30 which may explain the differential emotional control, mindset, and resilience between young adults and matured adults. As a result, dietary factors may influence mental health differently in these two populations. To study dietary intake, dietary practices and exercise in young adults (YA) (18-29 years) versus matured adults (MA) (30 years and older) in relation to mental distress. Another aim was to assess whether mental well-being potentially stimulates healthy eating, healthy practices, and exercising. An anonymous internet-based survey was sent through social media platforms to different professional and social group networks. Best-fit models were constructed using the backward regression analysis to assess the relationship between dietary variables, exercise, and mental distress in YA versus MA. YA mood seems to be dependent on food that increases availability of neurotransmitter precursors and concentrations in the brain (such as frequent meat consumption and exercise, respectively). However, MA mood may be more reliant on food that increases availability of antioxidants (fruits) and abstinence of food that inappropriately activates the sympathetic nervous system (coffee, high glycemic index, and skipping breakfast). Level of brain maturation and age-related changes in brain morphology and functions may necessitate dietary adjustments for improving mental well-being.

    A 3-month feeding experiment was conducted in an in-door seawater system to investigate the effect of dietary vitamin E (Ve) on the sperm quality of turbot ( Scophthalmus maximus). D-α-tocopherol acetate was supplemented to the basal (control) diet (65.14 mg kg-1 Ve) to obtain low and high levels of dietary Ve (244.60 mg kg-1, LVe; 721.60 mg kg-1, HVe). Compared with the control, sperm concentration was significantly increased in Ve-supplemented groups (LVe and HVe); while relative sperm volume and testis-somatic index were significantly increased in group HVe only. Sperm motility duration was significantly longer in group HVe than in the control, but no significant difference was observed in percent motility among groups. Sperm size, the uniformity of mitochondrial size, and the integrity of mitochondria cristae and plasma membrane were improved by dietary Ve, especially in HVe. The content of Ve in testis and liver as well as polyunsaturated fatty acids in sperm increased with dietary Ve. These results suggested that dietary Ve, especially at the high level (721.60 mg kg-1), significantly improved sperm concentration and motility duration and maintained normal sperm morphology of turbot.

    To explore the possibility of applying the concept of various stages of dietary behavior changes in Hangzhou residents. The dietary behavior was surveyed and analyzed in 1 388 Hangzhou residents with 18 year-old and older using the various dietary behavior change model model and stages of change. The proportion of Hangzhou residents with unhealthy dietary behavior was high and associated with gender and education level. The changes of dietary behavior could be divided into 5 stages, i.e. preintention, intention, preparation, action and maintenance. These stages of change happen consecutively. The changes of unhealthy dietary behavior do not match the improvement of health knowledge. Although a significant proportion of the residents understand that it is unhealthy to eat too much fat, pickles and high salt food, there are only a few of them really take action to reduce the consumption of these foods and to consume more milk, fruit and vegetable. There are multiple factors that affect the changes of dietary behavior in people. The changes of dietary behavior occur in various consecutive stages. Different intervention measures should be applied to people in different dietary behavior changes.

    In Mali, a large area of rice is planted with the local rice, O. glaberrima which under conditions of low rainfall and flood water is more hardy to stress than the introduced O. sativa cultivars. A program to improve the local varieties of O. glaberrima by induced mutations was started in 1988. Ten local varieties were irradiated with 20 and 30 krad. In M{sub 4} of cv. `Gorbal`, irradiated with 20 krads, 13 variants were selected. Five of these were evaluated in M{sub 5} for their agronomic performance. The induced mutants in the remaining 9 varieties were highly sterile with 90% or more sterility in the M{sub 2} and M{sub 3}. Irradiation with 20-30 krad gave high survival (70-95%), and several mutants with white kernel were obtained from the red seeded types. Nearly two-third of the identified mutants had white caryopsis. There is better consumer acceptance of the white seeded type of rice than the red seeded varieties in Mali and the white seeded mutants may have an added premium in the market. The field performance of the M{sub 5} mutants was investigated. Preliminary results showed that some of mutants derived from cv. `Gorbal` were early in maturity and had more panicles per plant, but had a lower 1000-kernel weight, and did not differ from the parent in grain yield. Additional trials are planned to establish potential of the mutants for yield and quality. Three more cultivars of O. glaberrima - `Haira`, `Tombo` and `Yele` - were irradiated with 20 and 60 krads, and gave 75, 81 and 72% seed viability, respectively. M{sub 1} showed reduced plant height. Selection for non-shattering of grains shall be carried out in M{sub 2}. Any plants which are non-shattering but sterile shall be crossed with the parent to recover the mutant types. The taxonomic status of cv. `Gorbal` is not very clear. Isozyme patterns suggest that this cultivar may belong to O. sativa and not to O. glaberrima. To establish its taxonomic status, crosses shall be made with O. sativa and O

    Between 1979 and 1981 seeds of the early ripening Swedish variety ''Fiskeby V'' were treated with N-nitroso-N-methylurea, sodium azide or gamma rays. Induced mutants were selected which are characterized by longer stalk, higher insertion point of the lowest pods and improved grain yield as well as sufficiently early maturity. Starting from 60 000 treated seeds, 6 mutant lines were developed, and in 1988 one variety named ''Dorado'' was released. Under optimal agrotechnical conditions in fields of 2-10 ha ''Dorado'' achieved grain yields between 1,5 and 2,3 t/ha during the last four years. It is intended to grow this variety in the middle and southern districts of the German Democratic Republic, primarily for human consumption. A technology for growing this variety was recommended

    This intervention sought to promote healthy eating with the ultimate goal of reducing childhood obesity risk. Three hundred and sixty-one Latino families living on the US-Mexico border with at least one child between 7-13 years of age were eligible to participate. Families randomly assigned to the four-month intervention received 14 contacts with a promotora (community health worker), consisting of 11 home visits and three telephone calls; the control condition was a delayed treatment intervention. Children reported on their dietary intake at baseline, immediately post-intervention and at the six month follow-up visit. The intervention reduced weekly consumption of fast food (p<0.05). A dose-response relationship was observed such that for every seven hours of promotora contact, monthly variety of fruits (p<0.01) and vegetables (p<0.01) increased by one. No other intervention effects were observed. Family-based interventions can improve children's eating habits, with the amount of contact with the promotora being key to success.

    This article reviews the current knowledge of the health effects of dietary fiber and prebiotics and establishes the position of prebiotics within the broader context of dietary fiber. Although the positive health effects of specific fibers on defecation, reduction of postprandial glycemic response, and maintenance of normal blood cholesterol levels are generally accepted, other presumed health benefits of dietary fibers are still debated. There is evidence that specific dietary fibers improve the integrity of the epithelial layer of the intestines, increase the resistance against pathogenic colonization, reduce the risk of developing colorectal cancer, increase mineral absorption, and have a positive impact on the immune system, but these effects are neither generally acknowledged nor completely understood. Many of the latter effects are thought to be particularly elicited by prebiotics. Although the prebiotic concept evolved significantly during the past two decades, the line between prebiotics and nonprebiotic dietary fiber remains vague. Nevertheless, scientific evidence demonstrating the health-promoting potential of prebiotics continues to accumulate and suggests that prebiotic fibers have their rightful place in a healthy diet.

    Diet plays a crucial role for maintaining normal growth and development while optimizing glycemic control in children with diabetes. Dietary restrictions, in a diabetic child's diet may lead to micronutrient deficiencies. To examine dietary nutritional deficiencies of Asian Indian children with Type 1 diabetes mellitus and develop micronutrient-rich recipes suitable for them. Anthropometry, diet (3-day recall) of 70 children with diabetes (24 boys) was recorded. Daily nutrient intakes and nutrient content of recipes were estimated using CDIET version 2.0. Mean intake amongst children for energy was 79% of Indian Recommended Dietary Allowance (RDA), protein was 105% RDA, but fat intakes were high (143% RDA). Mean intakes of riboflavin, β carotene, zinc, iron were less than 50%, and thiamin and calcium were around 60% RDA suggesting a possible multiple micronutrient deficiency. Based on popularly consumed snacks, 20 healthy recipes were devised that can be incorporated in children's diet. Mean energy content of new recipes was similar to routine snacks (281±28 kcal/100 g vs 306±27 kcal/100 g cooked weight). However, the mean vitamin and mineral content of new recipes was significantly higher (pcontent (zinc, calcium and iron) and twofold increase in total vitamin content (β carotene, vitamin C, vitamin B-1, B-2, and B-3) in new recipes compared with the routine snacks. Multiple dietary micronutrient deficiencies are observed in diabetic children. Addition of newly developed recipes in their everyday diet may help to enhance micronutrient intakes without increasing their energy load.

    Aboriginal people access diabetes and nutrition education less than non-Aboriginal people. Culturally appropriate, effective and accessible diabetes and nutrition education for Aboriginal people is urgently needed. A qualitative approach was used to explore the experiences of Aboriginal people who had attended cooking courses run at the Aboriginal Medical Service Western Sydney between 2002 and 2007. Data from 23 semi-structured interviews were analysed thematically. Despite reported improvements in nutrition knowledge and cooking skills, the ability of participants to implement desired dietary changes varied. A new health diagnosis, such as diabetes, pre-diabetes, heart disease or cancer and the desire of participants to influence their families to lead healthier, diabetes-free lives were strong motivators for dietary change. In contrast, lack of family support for dietary change and a sense of social isolation caused by dietary change strongly impeded some participants' attempts to improve their diets. Other significant barriers were poor oral health and depression, the higher cost of healthier food and generational food preferences. Aboriginal cooking course participants faced multiple barriers to dietary change - social, financial, medical and historical. The family was the most crucial determinant of participant ability to achieve sustained dietary change.

    The Eastern Himalayan region of Northeast (NE) India is home to a large number of indigenous rice varieties, which may serve as a valuable genetic resource for future crop improvement to meet the ever-increasing demand for food production. However, these varieties are rapidly being lost due to changes in land-use and agricultural practices, which favor agronomically improved varieties. A detailed understanding of the genetic structure and diversity of indigenous rice varieties is crucial for efficient utilization of rice genetic resources and for developing suitable conservation strategies. To explore the genetic structure and diversity of rice varieties in NE India, we genotyped 300 individuals of 24 indigenous rice varieties representing sali, boro, jum and glutinous types, 5 agronomically improved varieties, and one wild rice species (O. rufipogon) using seven SSR markers. A total of 85 alleles and a very high level of gene diversity (0.776) were detected among the indigenous rice varieties of the region. Considerable level of genetic variation was found within indigenous varieties whereas improved varieties were monoporphic across all loci. The comparison of genetic diversity among different types of rice revealed that sali type possessed the highest gene diversity (0.747) followed by jum (0.627), glutinous (0.602) and boro (0.596) types of indigenous rice varieties, while the lowest diversity was detected in agronomically improved varieties (0.459). The AMOVA results showed that 66% of the variation was distributed among varieties indicating a very high level of genetic differentiation in rice varieties in the region. Two major genetically defined clusters corresponding to indica and japonica groups were detected in rice varieties of the region. Overall, traditionally cultivated indigenous rice varieties in NE India showed high levels of genetic diversity comparable to levels of genetic diversity reported from wild rice populations in various parts of the

    In this substudy of the effect of dietary nitrate on blood pressure, endothelial function, and insulin sensitivity in type 2 diabetes, we report the development of a novel nitrate depleted beetroot juice for use clinical trials and determine if dietary nitrate supplementation improved cognitive function in patients with type 2 diabetes mellitus. Beetroot juice was treated with the anion exchange resin Purolite A520e. UV-vis-spectrophotometry, and a blind taste test were performed along with determination of sugar content, measurement of ascorbate and dehydroascorbate, the ionic composition of juice and Proton NMR. Subsequently, 27 patients, age 67.2±4.9 years, (18 male) were recruited for a double blind, randomised, placebo-controlled crossover trial. Participants were randomised to begin in either order beetroot juice (nitrate content 7.5 mmol per 250 ml) or placebo (nitrate depleted beetroot juice nitrate content 0.002 mmol per 250 ml). At the end of each 2 week supplementation period cognitive function was assessed using E-prime, E-Studio software with 5 separate tests being performed. The tests utilised in the present study have been adapted from the Cambridge Neuropsychological Test Automated Battery (CANTAB). The differences in the UV-vis spectra were comparable to the natural variation found in differing cultivars. There were no discernable differences in taste, sugar content, or Proton NMR. Ascorbate and dehydroascorbate were undetectable in either juice. After 2 weeks of beetroot juice simple reaction time was significantly quicker in the active arm at 327±40 ms versus 341.8±52.7 ms in the placebo arm, mean difference 13.9±25.6 ms (95% CI 3.8-24.0 ms), p=0.009. No other measures of cognitive function differed between treatment arms. We have developed an effective placebo beetroot juice for use in trials of supplementation of dietary nitrate. Two weeks supplementation of the diet with 7.5 mmol of nitrate per day caused a significant improvement in

    The causes of motility disorder of gastrointestinal tract and in particular Irritable Bowel Syndrome IBS are multifold, leading to complexity of treatment and requirement of more precise investigation of different pharmacological and non-pharmacological approaches. The aim of the study was investigation and comparison of the dietary fiber intake among women with constipation-predominant irritable bowel syndrome (IBS-C) and without, improvement of the dietary fiber intake using interventions with less rough changes of food related behavior and study of its effects on the bowel function, general wellbeing and compliance of patients. In total 100 healthy women, without any clinical signs of gastrointestinal disorders and 98 women who met Rome III criteria of IBS-C were enrolled in the dietary fiber intake assessment survey. The dietary habits of all participants, as well as bowel function, digestive feelings and general wellbeing of patients at baseline, on the 7th and 14th day of dietary intervention was assessed by the means of adopted questionnaires. The dietary supplementation was provided during the breakfast with fiber enriched food - bread and muesli. Research data reviled significantly lower daily intake of dietary fiber among patients with IBS-C compared with healthy group. The main source of dietary fiber in IBS-C group was bread and cereals, therefore introduction of dietary fiber rich bread and muesli in the breakfast didn't affect diet-related habits and determined high compliance of patients. Two week long intervention significantly improved the bowel function and irritation related complains, the feeling of general wellbeing was considerably better on the endpoint as well.

  20. Effects of Dietary Flavonoids on Reverse Cholesterol Transport, HDL Metabolism, and HDL Function.

    Strong experimental evidence confirms that HDL directly alleviates atherosclerosis. HDL particles display diverse atheroprotective functions in reverse cholesterol transport (RCT), antioxidant, anti-inflammatory, and antiapoptotic processes. In certain inflammatory disease states, however, HDL particles may become dysfunctional and proatherogenic. Flavonoids show the potential to improve HDL function through their well-documented effects on cellular antioxidant status and inflammation. The aim of this review is to summarize the basic science and clinical research examining the effects of dietary flavonoids on RCT and HDL function. Based on preclinical studies that used cell culture and rodent models, it appears that many flavonoids (e.g., anthocyanidins, flavonols, and flavone subclasses) influence RCT and HDL function beyond simple HDL cholesterol concentration by regulating cellular cholesterol efflux from macrophages and hepatic paraoxonase 1 expression and activity. In clinical studies, dietary anthocyanin intake is associated with beneficial changes in serum biomarkers related to HDL function in a variety of human populations (e.g., in those who are hyperlipidemic, hypertensive, or diabetic), including increased HDL cholesterol concentration, as well as HDL antioxidant and cholesterol efflux capacities. However, clinical research on HDL functionality is lacking for some flavonoid subclasses (e.g., flavanols, flavones, flavanones, and isoflavones). Although there has been a tremendous effort to develop HDL-targeted drug therapies, more research is warranted on how the intake of foods or specific nutrients affects HDL function. © 2017 American Society for Nutrition.

    National and international agencies recommend a reduction in dietary sodium intake. However, some have questioned the wisdom of these policies. The goal of this report was to assess the findings and quality of studies that have examined the relationship between dietary sodium and both blood pressure and cardiovascular disease. Literature review of the available observational studies and randomized controlled trials, including systematic reviews and meta-analyses. A large body of evidence from observational studies and clinical trials documents a direct relationship between dietary sodium intake and the level of blood pressure, especially in persons with a higher level of blood pressure, African-Americans, and those who are older or have comorbidity, including chronic kidney disease. A majority of the available observational reports support the presence of a direct relationship between dietary sodium intake and cardiovascular disease but the quality of the evidence according to most studies is poor. The limited information available from clinical trials is consistent with a beneficial effect of reduced sodium intake on incidence of cardiovascular disease. The scientific underpinning for policies to reduce the usual intake of dietary sodium is strong. In the United States and many other countries, addition of sodium during food processing has led to a very high average intake of dietary sodium, with almost everyone exceeding the recommended goals. National programs utilizing voluntary and mandatory approaches have resulted in a successful reduction in sodium intake. Even a small reduction in sodium consumption is likely to yield sizable improvement in population health. © 2015 S. Karger AG, Basel.

    This study investigated the effect of different timings of milk intake on body iron stores and improvement in the dietary habit of female collegiate rhythmic gymnasts. Subjects took iron tablets at both breakfast and dinner times during a weight-loss period. In addition, subjects ingested low-fat milk twice a day either at breakfast or dinner (group I; n = 7), or between meals (group II; n = 6) for 3 mo. Blood was collected four times. Red blood cell count, hemoglobin, serum iron, ferritin and erythropoietin concentrations were measured. Subjects completed a dietary survey for three consecutive days before each blood sampling. The mean body fat in both groups I and II was significantly lower after 3 mo than at the start of the study (p meals. In conclusion, iron-supplemented meals via milk ingestion did not decrease body iron stores and maintained higher body iron stores compared to a diet that included milk intake between meals. Further, milk intake with meals is related to keeping regular meal times and frequency.

    Consumption of a high quantity and wide variety of vegetables is currently recommended for health. Dietary variety can be low, however, particularly for older adults. This study investigated the affective factors associated with the quantity and variety of vegetables consumed by older adults in France, Italy and the UK. Adults aged 65 years plus completed questionnaires on self-reported vegetable intake (quantity and variety), liking for vegetables, attitudes towards intake, and demographic variables. In 497 older adults (France, n = 187, Italy, n = 152, UK, n = 158), higher quantities of vegetables consumed were associated with a higher age, affluence score and liking for vegetables, and a lower importance in consumption of familiarity (smallest β = 0.11, p = 0.03). Greater variety was associated with a higher liking and importance of health benefits, and a lower importance of familiarity (smallest β = -0.11, p foods in vegetable consumption, and a particular role for concern for health benefits in the consumption of a greater variety of vegetables.

    Workplaces are a good setting for interventions that aim to support workers in achieving a healthier diet and body weight. However, little is known about the factors that impact on the feasibility and implementation of these interventions, and how these might vary by type of workplace and type of worker. The aim of this study was to explore the views of those involved in commissioning and delivering the Better Health at Work Award, an established and evidence-based workplace health improvement programme. One-to-one semi-structured interviews were conducted with 11 individuals in North East England who had some level of responsibility for delivering workplace dietary interventions. Interviews were transcribed verbatim and analysed using thematic framework analysis. A number of factors were felt to promote the feasibility and implementation of interventions. These included interventions that were cost-neutral (to employee and employer), unstructured, involved colleagues for support, took place at lunchtimes, and were well-advertised and communicated via a variety of media. Offering incentives, not necessarily monetary, was perceived to increase recruitment rates. Factors that militate against feasibility and implementation of interventions included worksites that were large in size and remote, working patterns including shifts and working outside of normal working hours that were not conducive to workers being able to access intervention sessions, workplaces without appropriate provision for healthy food on site, and a lack of support from management. Intervention deliverers perceived that workplace dietary interventions should be equally and easily accessible (in terms of cost and timing of sessions) for all staff, regardless of their job role. Additional effort should be taken to ensure those staff working outside normal working hours, and those working off-site, can easily engage with any intervention, to avoid the risk of intervention-generated inequalities (IGIs).

    Consumption of a cholesterol lowering dietary portfolio including plant sterols (PS), viscous fibre, soy proteins and nuts for 6 months improves blood lipid profile. Plant sterols reduce blood cholesterol by inhibiting intestinal cholesterol absorption and concerns have been raised whether PS consumption reduces fat soluble vitamin absorption. The objective was to determine effects of consumption of a cholesterol lowering dietary portfolio on circulating concentrations of PS and fat soluble vitamins. Using a parallel design study, 351 hyperlipidemic participants from 4 centres across Canada were randomized to 1 of 3 groups. Participants followed dietary advice with control or portfolio diet. Participants on routine and intensive portfolio involved 2 and 7 clinic visits, respectively, over 6 months. No changes in plasma concentrations of α and γ tocopherol, lutein, lycopene and retinol, but decreased β-carotene concentrations were observed with intensive (week 12: p = 0.045; week 24: p = 0.039) and routine (week 12: p = 0.031; week 24: p = 0.078) portfolio groups compared to control. However, cholesterol adjusted β-carotene and fat soluble compound concentrations were not different compared to control. Plasma PS concentrations were increased with intensive (campesterol:p = 0.012; β-sitosterol:p = 0.035) and routine (campesterol: p = 0.034; β-sitosterol: p = 0.080) portfolio groups compared to control. Plasma cholesterol-adjusted campesterol and β-sitosterol concentrations were negatively correlated (p portfolio diet reduces serum total and LDL-C levels while increasing PS values, without altering fat soluble compounds concentrations. The extent of increments of PS with the current study are not deleterious and also maintaining optimum levels of fat soluble vitamins are of paramount necessity to maintain overall metabolism and health. Results indicate portfolio diet as one of the best options for CVD risk reduction

    Crop improvement is a multifaceted micro-evolutionary process, involving changes in breeding approaches, planting configurations and consumption preferences of human beings. Recent research has started to identify the specific genes or genomic regions correlate to improved agronomic traits, however, an apparent blank between the genetic structure of crop elite varieties and their improving histories in diverse modern breeding programs is still in existence. Foxtail millet (Setaria italica) was one of the earliest cereal crops to be domesticated and served as a staple crop for early civilizations in China, where it is still widely grown today. In the present trial, a panel of foxtail millet elite varieties, which were released in the last sixty years in different geographical regions of China, was characterized using microsatellite markers (SSRs). A clear separation of two subpopulations corresponding to the two eco-geographical regions of foxtail millet production in China was identified by the dataset, which also indicated that in more recently released elite varieties, large quantities of accessions have been transferred from spring-sowing to summer-sowing ecotypes, likely as a result of breeding response to planting configurations. An association mapping study was conducted to identify loci controlling traits of major agronomic interest. Furthermore, selective sweeps involved in improvement of foxtail millet were identified as multi-diverse minor effect loci controlling different agronomic traits during the long-term improvement of elite varieties. Our results highlight the effect of transition of planting configuration and breeding preference on genetic evolvement of crop species.

    O'Brien, P

    1995-06-01

    Changes to healthier dietary patterns similar to those of traditional Mediterranean diets or those of the US government's dietary guidelines and food guide pyramid would require significant changes in American agricultural practices. The volume, mix, production, and marketing of agricultural commodities would need to be modified. Because differences between actual and recommended intakes for major food groups are quite large and affect a broad range of products, adjustments in supply and demand could overshadow past experience in dealing with such changes. New food and agriculture policies may well be needed to ease and accelerate agricultural adjustments, to improve nutritional characteristics of popular foods, and to promote desirable changes in consumers' food choices.

    The consumption of dietary supplements is highest among athletes and it can represent potential a health risk for consumers. The aim of this study was to determine the prevalence of consumption of dietary supplements by road runners. We interviewed 817 volunteers from four road races in the Brazilian running calendar. The sample consisted of 671 male and 146 female runners with a mean age of 37.9 ± 12.4 years. Of the sample, 28.33% reported having used some type of dietary supplement. The main motivation for this consumption is to increase in stamina and improve performance. The probability of consuming dietary supplements increased 4.67 times when the runners were guided by coaches. The consumption of supplements was strongly correlated (r = 0.97) with weekly running distance, and also highly correlated (r = 0.86) with the number of years the sport had been practiced. The longer the runner had practiced the sport, the higher the training volume and the greater the intake of supplements. The five most frequently cited reasons for consumption were: energy enhancement (29.5%), performance improvement (17.1%), increased level of endurance (10.3%), nutrient replacement (11.1%), and avoidance of fatigue (10.3%). About 30% of the consumers declared more than one reason for taking dietary supplements. The most consumed supplements were: carbohydrates (52.17%), vitamins (28.70%), and proteins (13.48%). Supplement consumption by road runners in Brazil appeared to be guided by the energy boosting properties of the supplement, the influence of coaches, and the experience of the user. The amount of supplement intake seemed to be lower among road runners than for athletes of other sports. We recommend that coaches and nutritionists emphasise that a balanced diet can meet the needs of physically active people.

    Crude lecithin, a mixture of mainly phospholipids, potentially helps to increase the systemic availability of dietary omega-3 polyunsaturated fatty acids (n-3 PUFA), such as docosahexaenoic acid (DHA). Nevertheless, no clear data exist on the effects of prolonged combined dietary supplementation of DHA and lecithin on RBC and plasma PUFA levels. In the current experiments, levels of DHA and choline, two dietary ingredients that enhance neuronal membrane formation and function, were determined in plasma and red blood cells (RBC) from rats after dietary supplementation of DHA-containing oils with and without concomitant dietary supplementation of crude lecithin for 2-3 weeks. The aim was to provide experimental evidence for the hypothesized additive effects of dietary lecithin (not containing any DHA) on top of dietary DHA on PUFA levels in plasma and RBC. Dietary supplementation of DHA-containing oils, either as vegetable algae oil or as fish oil, increased DHA, eicosapentaenoic acid (EPA), and total n-3 PUFA, and decreased total omega-6 PUFA levels in plasma and RBC, while dietary lecithin supplementation alone did not affect these levels. However, combined dietary supplementation of DHA and lecithin increased the changes induced by DHA supplementation alone. Animals receiving a lecithin-containing diet also had a higher plasma free choline concentration as compared to controls. In conclusion, dietary DHA-containing oils and crude lecithin have synergistic effects on increasing plasma and RBC n-3 PUFA levels, including DHA and EPA. By increasing the systemic availability of dietary DHA, dietary lecithin may increase the efficacy of DHA supplementation when their intake is combined.

    Metabolic syndrome (MetS) enhances salt sensitivity of blood pressure and is an important risk factor for cardiovascular disease. The effects of dietary salt restriction on cardiac pathology associated with metabolic syndrome remain unclear. We investigated whether dietary salt restriction might ameliorate cardiac injury in DahlS.Z-Lepr(fa)/Lepr(fa) (DS/obese) rats, which are derived from a cross between Dahl salt-sensitive and Zucker rats and represent a model of metabolic syndrome. DS/obese rats were fed a normal-salt (0.36% NaCl in chow) or low-salt (0.0466% NaCl in chow) diet from 9 weeks of age and were compared with similarly treated homozygous lean littermates (DahlS.Z-Lepr(+)/Lepr(+), or DS/lean rats). DS/obese rats fed the normal-salt diet progressively developed hypertension and showed left ventricular hypertrophy, fibrosis, and diastolic dysfunction at 15 weeks. Dietary salt restriction attenuated all of these changes in DS/obese rats. The levels of cardiac oxidative stress and inflammation and the expression of cardiac renin-angiotensin-aldosterone system genes were increased in DS/obese rats fed the normal-salt diet, and dietary salt restriction downregulated these parameters in both DS/obese and DS/lean rats. In addition, dietary salt restriction attenuated the increase in visceral adipose tissue inflammation and the decrease in insulin signaling apparent in DS/obese rats without reducing body weight or visceral adipocyte size. Dietary salt restriction did not alter fasting serum glucose levels but it markedly decreased the fasting serum insulin concentration in DS/obese rats. Dietary salt restriction not only prevents hypertension and cardiac injury but also ameliorates insulin resistance, without reducing obesity, in this model of metabolic syndrome. © 2014 The Authors.

    Full Text Available Acculturation, the subsequent changes that occur in one culture after continuous first hand contact with another culture, impacts the dietary habits and health risks of individuals. This study examines the acculturation, dietary habits and anthropometric measurements in a sample of 210 first generation Filipino American immigrants in New Jersey (NJ. Acculturation was measured using the Short Acculturation Scale for Filipino Americans (ASASFA. Dietary acculturation was measured using the Dietary Acculturation Questionnaire for Filipino Americans (DAQFA and dietary intake was determined using the Block’s Brief Food Frequency Questionnaire (BFFQ. Anthropometric measurements were obtained including weight, height and waist circumference. Acculturation had a significant negative relationship with Filipino Dietary acculturation. Western dietary acculturation was significantly correlated with caloric intake (r(208 = 0.193, p < 0.01, percentage fat intake (r(208 = 0.154, p < 0.05, percentage carbohydrate intake (r(208 = −0.172, p < 0.05, Body Mass Index (BMI (r(208 = 0.216, p < 0.01 and waist circumference (r(208 = 0.161, p < 0.01. There was no significant correlation between Filipino dietary acculturation, dietary intake and anthropometric measurements. The results showed that Filipino American immigrants have increased risks including increased BMI, waist circumference and increased fat intake. Over all, this research highlighted some dietary changes and their effects on dietary intake and health status.

Nutritional adequacy was evaluated and compared using mean intake; the proportion of participants with intakes below Australian nutrient reference values (NRV), U.S. military dietary reference intakes (MDRI), and current sports nutrition recommendations; and probability estimates of nutrient inadequacy. Mean energy intake was 10,551 +/- 3,836 kJ/day with macronutrient distribution 18% protein, 31% fat, and 46% carbohydrate, consistent with Australian acceptable macronutrient distribution ranges. Mean protein intake (1.6 g . kg(-1) . d(-1)) was consistent with (>1.2 g . kg(-1) . d(-1)), and carbohydrate intake (4.5 g . kg(-1) . d(-1)), below, current sports nutrition recommendations (>5 g . kg(-1) . d(-1)), with 30% and 65% of individuals not meeting these levels, respectively. Mean micronutrient intake met the relevant NRV and MDRI except for vitamin D and folate. A proportion of participants failed to meet the estimated average requirement for folate (48%), calcium (24%), magnesium (19%), and iron (4%). Probability estimates of inadequacy identified intake of folate (44%), calcium (22%), iron (19%), and magnesium (15%) as inadequate. Interpretation of dietary adequacy is complex and varies depending on whether the mean, proportion of participants below the relevant NRV, or statistical probability estimate of inadequacy is used. Further research on methods to determine dietary adequacy in athlete populations is required.

    Rye products typically induce low insulin responses and appear to facilitate glucose regulation. The objective of this study was to investigate differences in postprandial glucose, insulin, and satiety responses between breads made from five rye varieties. Breads made from whole grain rye (Amilo, Rekrut, Dankowski Zlote, Nikita, and Haute Loire Pop) or a white wheat bread (WWB) were tested in a randomized cross-over design in 14 healthy subjects (50 g available starch). Metabolic responses were also related to the composition of dietary fiber and bioactive compounds in the breads and to the rate of in vitro starch hydrolysis. The Amilo and Rekrut rye breads induced significantly lower insulin indices (II) than WWB. Low early postprandial glucose and insulin responses (tAUC 0-60 min) were related to higher amounts of caffeic, ferulic, sinapic, and vanillic acids in the rye breads, indicating that the phenolic acids in rye may influence glycemic regulation. All rye breads induced significantly higher subjective feelings of fullness compared to WWB. A low II was related to a higher feeling of fullness and a lower desire to eat in the late postprandial phase (180 min). The data indicate that some rye varieties may be more insulin-saving than others, possibly due to differences in dietary fiber, rate of starch hydrolysis, and bioactive components such as phenolic acids.

    The incidence of gestational diabetes mellitus (GDM) is increasing and GDM might be prevented by improving diet. Few interventions have assessed the effects of dietary counselling on dietary intake of pregnant women. This study examined the effects of dietary counselling on food habits and dietary intake of Finnish pregnant women as secondary outcomes of a trial primarily aiming at preventing GDM. A cluster-randomized controlled trial was conducted in 14 municipalities in Finland, including 399 pregnant women at increased risk for developing GDM. The intervention consisted of dietary counselling focusing on dietary fat, fibre and saccharose intake at four routine maternity clinic visits. Usual counselling practices were continued in the usual care municipalities. A validated 181-item food frequency questionnaire was used to assess changes in diet from baseline to 26-28 and 36-37 weeks gestation. The data were analysed using multilevel mixed-effects linear regression models. By 36-37 weeks gestation, the intervention had beneficial effects on total intake of vegetables, fruits and berries (coefficient for between-group difference in change 61.6 g day(-1), 95% confidence interval 25.7-97.6), the proportions of high-fibre bread of all bread (7.2% units, 2.5-11.9), low-fat cheeses of all cheeses (10.7% units, 2.6-18.9) and vegetable fats of all dietary fats (6.1% -units, 2.0-10.3), and the intake of saturated fatty acids (-0.67 energy-%-units, -1.16 to -0.19), polyunsaturated fatty acids (0.38 energy-%-units, 0.18-0.58), linoleic acid (764 mg day(-1), 173-1354) and fibre (2.07 g day(-1) , 0.39-3.75). The intervention improved diet towards the recommendations in pregnant women at increased risk for GDM suggesting the counselling methods could be implemented in maternity care. © 2012 John Wiley & Sons Ltd.

    To evaluate dietary supplement use in young Canadian athletes, their motivation for consuming supplements, and their sources of information. A questionnaire tested for content validity and reliability was administered to 567 athletes between the ages of 11 and 25 years from the Canadian athletic community in face-to-face meetings. Demographics and sport variables were analyzed using descriptive statistics. Fisher's exact tests were used to examine dietary supplementation patterns and sources of information regarding dietary supplement use between categories of gender, age, sport type, and competition level. Ninety-eight percent of athletes were taking at least one dietary supplement. Males were more likely to consume protein powder, energy drinks, recovery drinks, branched chain amino acids, beta-alanine, and glutamine (p performance. Primary sources of information were family and friends, coaches, and athletic trainers; with 48% of athletes having met with a dietitian. Preferred means of education included individual consultations, presentations, and the internet. The majority of young athletes are using dietary supplements with the belief they will improve performance and health; however, may not always have reliable information. Educational programs using individual consultations and electronic media are recommended for this demographic.

    Colorectal cancer (CRC) is now a major public health problem with heavy morbidity and mortality in rural Africans despite the lingering dietary fiber-rich foodstuffs consumption. Studies have shown that increased intake of dietary fiber which contribute to low fecal pH and also influences the activity of intestinal microbiota, is associated with a lowered risk for CRC. However, whether or not the apparent high dietary fiber consumption by Africans do not longer protects against CRC risk is unknown. This study evaluated dietary fiber intake, fecal fiber components and pH levels in CRC patients. Thirty-five subjects (CRC=21, control=14), mean age 45 years were recruited for the study. A truncated food frequency questionnaire and modified Goering and Van Soest procedures were used. We found that all subjects consumed variety of dietary fiber-rich foodstuffs. There is slight preponderance in consumption of dietary fiber by the control group than the CRC patients. We also found a significant difference in the mean fecal neutral detergent fiber, acid detergent fiber, hemicellulose, cellulose and lignin contents from the CRC patients compared to the controls ( P fiber components and stool pH levels between the 2 groups may relate to CRC incidence and mortality in rural Africans. There is crucial need for more hypothesis-driven research with adequate funding on the cumulative preventive role of dietary fiber-rich foodstuffs against colorectal cancer in rural Africans "today."

    Many obese subjects suffer from an increased hedonic drive to consume palatable foods, i.e., hedonic hunger, and often show unfavorable dietary habits. Here, we investigated changes in the hedonic hunger and dietary habits after Roux-en-Y gastric bypass (RYGB) surgery. Forty-four severely obese patients were examined before and on average 15.9 ± 0.9 months after RYGB surgery with the Power of Food Scale (PFS), a questionnaire that reliably measures an individual's motivation to consume highly palatable foods but not actual consumptive behavior. Dietary habits were assessed by a food frequency questionnaire. After the RYGB procedure, patients showed markedly lower aggregated PFS scores and sub-domain scores related to generally available, physically present, as well as tasted foods than before the surgery (all P habits after the surgery were characterized by a more frequent consumption of poultry, fish, eggs, and cooked vegetables (P habits characterized by an increased intake of protein-rich foods and vegetables and a reduced consumption of sugar-containing snacks and beverages after RYGB surgery. Based on these findings, it can be speculated that the reduction of the hedonic drive to consume palatable foods induced by RYGB surgery helps severely obese patients to establish healthier dietary habits.

    Full Text Available Calcium is an important structural component of the skeletal system. Although an adequate intake of calcium helps to maintain bone health and reduce the risk of osteoporosis, many women do not meet recommended daily intakes of calcium. Previous interventions studies designed to increase dietary intake of women have utilized primarily dairy sources of calcium or supplements. However, lactose intolerance, milk protein allergies, or food preferences may lead many women to exclude important dairy sources of dietary calcium. Therefore, we undertook a 9 week randomized crossover design trial to examine the potential benefit of including a non-dairy source of calcium in the diet of women. Following a 3 week run-in baseline period, 35 healthy women > 18 years were randomized by crossover design into either Group I or Group II. Group I added 2 calcium-fortified cereal bars daily (total of 400 mg calcium/day (intervention to their usual diet and Group II continued their usual diet (control. At the end of 3 weeks, diets were switched for another 3 weeks. Intakes of calcium and energy were estimated from 3-day diet and supplemental diaries. Wilcoxon signed-rank tests were used for within group comparisons and Mann Whitney U tests were used for between group comparisons of calcium and energy intake. Dietary calcium was significantly higher during intervention (1071 mg/d when participants consumed 2 calcium-fortified cereal bars daily than during the baseline (720 mg/d, P <0.0001 or control diets (775 mg/d, P = 0.0001 periods. Furthermore, the addition of 2 calcium-fortified cereal bars daily for the 3 week intervention did not significantly increase total energy intake or result in weight gain. In conclusion, consumption of calcium-fortified cereal bars significantly increased calcium intake of women. Further research examining the potential ability of fortified cereal bars to help maintain and improve bone health of women is warranted.ClinicalTrials.gov NCT

    The aim of this study was to clarify the impact of wearing removable partial dentures (RPDs) replacing a small number of teeth on dietary intake. Participants had at least 20 teeth and were classified as Eichner B1 or B2. The participants underwent dental and oral examinations, and their dietary intake was assessed. Analysis of covariance showed that RPD wearers consumed more vegetables, n-3 fatty acids, calcium, vitamin A, and dietary fiber than nonwearers after adjusting for possible confounding factors. It is concluded that RPDs are effective for improving dietary intake even in participants who have lost a small number of teeth.

    Mung bean (Vigna radiata) is an important crop. Marathwada Agricultural University has developed and released a variety BM4 for Western Zone. This variety has got yield potential of 1200-1300 kg/ha. However it has small grain size and dull green colour resulting in less dahl recovery and less market price. To improve these parameters, a mutation breeding programme was taken up. Dry seeds of variety BM4 were treated with 10, 15, 25 kR gamma rays at BARC Mumbai. In M 1 generation, germination decreased with increased dose of gamma rays. Twenty five kR showed lowest germination, 10 and 15 kR showed satisfactory germination. Individual plants were harvested and plant to row progenies were grown in M 2 in augmented block design. Range of mean was 39.8 to 77.2, 6.3 to 45.4, 1.85 to 3.25 and 9.2 to 60.0 for plant height (cm), number of pods/plant, test weight (g) and yield/plant(g) respectively. Out of 3 doses of gamma rays 10 kR proved more effective in increasing seed size, number of pods and seed yield/plant. (author)

    Lifestyle modification programs (LMPs) can provide individuals with behavioral skills to sustain long-term changes to their physical activity (PA) levels and dietary habits. Yet, there is much work to be done in the translation of these programs to community settings. This review identified LMPs that focused on changing both PA and dietary behaviors and examined common features and barriers faced in their translation to community settings. A search of multiple online databases was conducted to identify LMPs that included participants over the age of 18 who enrolled in LMPs, offered in community settings, and had the goal of improving both PA and dietary behaviors. Data were extracted on participant demographics, study design characteristics, and study outcome variables including changes in PA, dietary habits, body weight, and clinical outcomes. We identified 27 studies that met inclusion criteria. Despite high levels of retention and adherence to the interventions, varying levels of success were observed in increasing PA levels, improving dietary habits, reducing body weight, and improving clinic outcomes. LMPs addressing issues of PA and dietary habits can be successfully implemented in a community setting. However, inconsistent reporting of key components in the translation of these studies (participant recruitment, utilization of behavioral strategies) may limit their replication and advancement of future programs. Future efforts should better address issues such as identifying barriers to participation and program implementation, utilization of community resources, and evaluating changes across multiple health behaviors.

    Dietary guidelines provide evidence-based statements on food choices to meet nutritional requirements and reduce the risk of prevailing chronic disease. They involve a substantial amount of research translation, and their implementation has important health consequences. Foods, however, are complex combinations of nutrients and other compounds that act synergistically within the food and across food combinations. In addition, the evidence base underpinning dietary guidelines accesses research that reflects different study designs, with inherent strengths and limitations. We propose a systematic approach for the review of evidence that begins with research on dietary patterns. This research will identify the combinations of foods that best protect, or appear deleterious to, health. Next, we suggest that evidence be sought from research that focuses on the effects of individual foods. Finally, nutrient-based research should be considered to explain the mechanisms by which these foods and dietary patterns exert their effects, take into account the effects of ingredients added to the food supply, and enable assessments of dietary sufficiency. The consideration of individual nutrients and food components (e.g., upper limits for saturated fat, added sugar, and sodium) provides important benchmarks for evaluating overall diet quality. The concepts of core and discretionary foods (nutrient-rich and nutrient-poor foods, respectively) enable distinctions between foods, and this has implications for the relation between food policy and food manufacturing. In summary, evidence supporting healthy dietary patterns provides the foundation for the development of dietary guidelines. Further reference to individual foods and nutrients follows from the foundation of healthy dietary patterns. PMID:27184272

Afterward, the rats were fed diets with 50% of the kilocalories of fat derived from lard replaced by the different dietary oils. In addition, a control group fed a standard diet (4% kcal fat and a high fat fed group (45% kcal were maintained. The treatment period was 32 weeks. The endpoints evaluated included motor and sensory nerve conduction velocity, thermal sensitivity, innervation of sensory nerves in the cornea and skin, and vascular relaxation by epineurial arterioles.Results: Menhaden oil provided the greatest benefit for improving peripheral nerve damage caused by dietary obesity. Similar results were obtained when we examined acetylcholine-mediated vascular relaxation of epineurial arterioles of the sciatic nerve. Enriching the diets with fatty acids derived from the other oils provided minimal to partial improvements.Conclusion: These studies suggest that omega-3 polyunsaturated fatty acids derived from fish oil could be an effective treatment for neural and vascular complications associated with obesity.

    Full Text Available Crop improvement is a multifaceted micro-evolutionary process, involving changes in breeding approaches, planting configurations and consumption preferences of human beings. Recent research has started to identify the specific genes or genomic regions correlate to improved agronomic traits, however, an apparent blank between the genetic structure of crop elite varieties and their improving histories in diverse modern breeding programs is still in existence. Foxtail millet (Setaria italica was one of the earliest cereal crops to be domesticated and served as a staple crop for early civilizations in China, where it is still widely grown today. In the present trial, a panel of foxtail millet elite varieties, which were released in the last sixty years in different geographical regions of China, was characterized using microsatellite markers (SSRs. A clear separation of two subpopulations corresponding to the two eco-geographical regions of foxtail millet production in China was identified by the dataset, which also indicated that in more recently released elite varieties, large quantities of accessions have been transferred from spring-sowing to summer-sowing ecotypes, likely as a result of breeding response to planting configurations. An association mapping study was conducted to identify loci controlling traits of major agronomic interest. Furthermore, selective sweeps involved in improvement of foxtail millet were identified as multi-diverse minor effect loci controlling different agronomic traits during the long-term improvement of elite varieties. Our results highlight the effect of transition of planting configuration and breeding preference on genetic evolvement of crop species.

    Following a cancer diagnosis, dietary supplements are reportedly used by 20%-80% of individuals. Supplements are most commonly used by breast cancer survivors, followed by patients with prostate, colorectal, and lung cancers, which is not surprising since these are the most common types of cancer diagnosed in adults. Reasons cited for such use include improving quality of life, reducing symptoms related to treatment and/or the disease process, and recommendation from medical practitioners; family and friends may also be an influence. However, controversy surrounds the use of dietary supplements, particularly during treatment-specifically, whether supplements affect treatment efficacy is unknown. This article discusses the evidence related to common dietary supplements used to prevent cancer or a recurrence.

    Dietary choices in out-of-home eating are key for individual as well as for public health. These dietary choices are caused by a wide array of determinants, one of which is automatic decision-making. Nudging is attracting considerable interest due to its understanding and application of heuristic biases among consumers. The aim of this study is to test and compare three nudges in promoting vegetable consumption among test persons in a food lab-based experiment. The initial sample consisted of 88 participants recruited in Copenhagen, Denmark. Each study participant was randomly assigned to one of the three experiments: priming, default and perceived variety. The priming arm of the experiment consisted of creating a leafy environment with green plants and an odour of herbs. In the default arm of the experiment, the salad was pre-portioned into a bowl containing 200g of vegetables. The third experiment divided the pre-mixed salad into each of its components, to increase the visual variety of vegetables, yet not providing an actual increase in items. Each individual was partaking twice thus serving as her/his own control, randomly assigned to start with control or experimental setting. The default experiment successfully increased the energy intake from vegetables among the study participants (124 kcal vs. 90 kcal in control, ppriming condition and perceived variety reduced the total energy intake among the study participants (169 kcal, peffects, whether it is increasing intake of healthy components, or limiting intake of unhealthy meal components. This work has demonstrated that consumer behaviour can be influenced without restricting or providing incentives for behaviour change. The present findings have promising application to the foodservice sector.

    The Chotanagpur plateau region of Bihar is the main potential area for groundnut cultivation in the State. Var. AK 12-24 - an early, bunch type - has been the predominant variety under cultivation. Because of special nature of soil and rainfall pattern of this area, it is desirable to evolve a variety with early to mid-early maturity and bunch habit, but with improved yield potential over the ruling var. AK 12-24. Two bold podded mutants BP 1 and BP 2 were obtained throuo.h gamma irradiation of var 41-C which is a late maturing variety (135-140 days), spreading in habit and with medium kernel and pod size, whereas the mutant varieties have early (110-115 days for BP 1) to mid-early (115-120 days for BP 2) maturity, bunch habit and bold kernel and pods (HKW 55-60 gm for BP 1 and 60-66 gms for BP 2). Both have 20-25% higher yield potential over AK 12-24. The results of 3 years' yield evaluation trials at Kanke and one year minikit trials at different locations in Bihar show that BP 1 and BP 2 have significantly outyielded the check AK 12-24 and were at par with each other. Both varieties -because of their bold seededness - come under HPS type and have good export market. These varieties have now been released by the Rajendra Agricultural University as Sonya Bold 1 and Sonya Bold 2 for cultivation in Bihar. (author)

    Full Text Available Background: Calcium (Ca plays an important role in bone formation. Attaining optimal bone mass and peak bone densities is essential to prevent osteoporotic fractures in future life. In conditions of Ca deficiency, Ca from the bones maintains the blood levels of Ca leading to its depletion in bones. Calcium depletion leads to poor bone density and a higher risk of osteoporosis particularly in women who have repeated episodes of pregnancy and lactation.Aim & Objective: To assess the dietary intake of calcium.Material Methods: the study was conducted among 200 healthy women of reproductive age group of 20-49 years.Result: The dietary intake of calcium was less than the Recommended Dietary Allowances of 600mg/day. Women from upper socioeconomic class had a higher intake of dietary calcium 435±268 mg/day as compared to women from low socioeconomic class with a dietary intake of 295±163 mg/day.Conclusion: The dietary intake of calcium improved with an increase in socioeconomic class.

    Full Text Available Targeted deletion of S6 kinase (S6K 1 in mice leads to higher energy expenditure and improved glucose metabolism. However, the molecular mechanisms controlling these effects remain to be fully elucidated. Here, we analyze the potential role of dietary lipids in regulating the mTORC1/S6K system. Analysis of S6K phosphorylation in vivo and in vitro showed that dietary lipids activate S6K, and this effect is not dependent upon amino acids. Comparison of male mice lacking S6K1 and 2 (S6K-dko with wt controls showed that S6K-dko mice are protected against obesity and glucose intolerance induced by a high-fat diet. S6K-dko mice fed a high-fat diet had increased energy expenditure, improved glucose tolerance, lower fat mass gain, and changes in markers of lipid metabolism. Importantly, however, these metabolic phenotypes were dependent upon dietary lipids, with no such effects observed in S6K-dko mice fed a fat-free diet. These changes appear to be mediated via modulation of cellular metabolism in skeletal muscle, as shown by the expression of genes involved in energy metabolism. Taken together, our results suggest that the metabolic functions of S6K in vivo play a key role as a molecular interface connecting dietary lipids to the endogenous control of energy metabolism.

    To clarify directions for research and practice, research literature evaluating nutrition and dietary interventions in college and university settings was reviewed. Systematic search of database literature. Postsecondary education. Fourteen research articles evaluating randomized controlled trials or quasi-experimental interventions targeting dietary outcomes. Diet/nutrition intake, knowledge, motivation, self-efficacy, barriers, intentions, social support, self-regulation, outcome expectations, and sales. Systematic search of 936 articles and review of 14 articles meeting search criteria. Some in-person interventions (n = 6) show promise in improving students' dietary behaviors, although changes were minimal. The inclusion of self-regulation components, including self-monitoring and goal setting, may maximize outcomes. Dietary outcomes from online interventions (n = 5) were less promising overall, although they may be more effective with a subset of college students early in their readiness to change their eating habits. Environmental approaches (n = 3) may increase the sale of healthy food by serving as visual cues-to-action. A number of intervention approaches show promise for improving college students' dietary habits. However, much of this research has methodological limitations, rendering it difficult to draw conclusions across studies and hindering dissemination efforts.

    Full Text Available Aim: To evaluate the methane generation potential and digestibility of different (normal and three high-quality protein maize [HQPM] varieties of maize fodder with goat rumen liquor in vitro. Materials and Methods: Methane production potential and digestibility of different varieties of maize fodder were tested in in vitro gas production test. Seven varieties of maize, four normal (HTHM 5101, DHM 117, HM 5, and Shaktiman/900 M Gold, and three high-quality protein (HQPM 5, HQPM 7, and HQPM 9/Vivek were grown in different plots under the same environmental and agro-climatic conditions. Fodders were harvested at 45-50 days of sowing, and the representative samples of fodder from different varieties of maize were collected for analysis. Dried and grinded form of these maize fodder varieties was tested for gas, methane, and digestibility using goat rumen microflora in in vitro gas syringes. Results: Gas production (ml/g dry matter [DM] was highest for HM5 variety (97.66, whereas lowest for HQPM 9 variety (64.22. Gas production (ml/g degraded DM [DDM] and methane (% were statistically similar in different varieties of maize fodder. The methane production expressed as ml/g DM and ml/g DDM was significantly (p<0.05 highest for HM 5 (14.22 and 26.62 and lowest for DHM 117 variety (7.47 and 14.13. The in vitro DM digestibility (% and in vitro organic matter digestibility (% varied from 47.48 (HQPM 5 to 52.05 (HQPM 9 and 50.03 (HQPM 7 to 54.22 (HM 5, respectively. Conclusion: The present study concluded that DHM 117 maize variety fodder has lowest methane generation potential and incorporating it in the dietary regime of ruminants may contribute to lower methane production.

    In an effort to improve the yield of Kenyan sesame cultivars the seeds of three cultivars, SPS SIK6, SIK 096 and SPS SIK 50/1 were subjected to 300Gy, 400Gy and 600Gy of gamma rays. A first batch of seeds were subjected to these treatments in March 1994 (Experiment I) while the second batch was treated in March 1995 (Experiment II). The M 1 , M 2 , M 3 and M 4 generations of experiment I and M 1 generation of Experiment II were raised at the University of Nairobi Dryland Research Field Station, Kibwezi from 1994 to 1996. The M 6 and M 7 generations of Experiment I and M 2 of Experiment II were raised at Siaya Farmer's Training Centre in 1997. The effects of radiation in M 1 generation were expressed in reduced and delayed seedling emergence, reduced plant height, sectorial deformed plants, delayed flowering and extremely low yield. There was increased variation in M 2 for most evaluated traits. Plants in M 2 and subsequent generations were scored for a number of yield related morphological traits and days to flowering. Selection was done in the early generations for increased capsule number and earliness. As a result of selection, a total of 88 lines from M 4 generation were used to derive M 5 generation. Further selection in M 6 generation lead to 35 lines being retained for preliminary yield trials in M 7 generations. (author)

    Black rice is a local rice variety that contains a high level of anthocyanin pigment. Anthocyanin has been reported to be very effective in reducing cholesterol levels as well as cancer cell invasion. One of the main problems in rice cultivation is lack of water. System of Rice Intensification (SRI) has shown to be able to increase rice productivity by increasing the number of tillers. This system is known as a water-efficient cultivation. Other rice cultivation barrier is related to the use of nitrogen fertilizer. One of replacement of nitrogen fertilizer is by adding azolla. The objective of this research was identifying growth and yield of organic black rice with intermittent irrigation and application of azolla. The plant material used was black rice Cempo variety from Sleman, Yogyakarta. This experiment utilized 4 dosages of azolla as the first treatment: 100 gm-2, 200 gm-2 and 400 gm-2. The second treatment was water supply consisted of continuous flooded 2 cm; flooded 2 cm every 3 days; flooded 2 cm every 6 days. The results depicted that the application of azolla was able to increase the growth of black rice. Azolla of 200 gm-2 and 400 gm-2 and intermittent 3 days to 6 days generated higher dry grain, anthocyanin and antioxidant. Azolla 200 gm-2 with intermittent irrigation 3 days could be a good combination to improve plant growth, yield and properties of local black rice.

    Reduced caloric intake including fasting, as well as the dietary composition or the timing of food intake, impact longevity, likely through a modification in the onset or the severity of chronic aging-related diseases such as cancer. As with pre- and post-operative dietary recommendations, evidence-based nutritional advice from healthcare professionals during and after cancer treatment is often vague or conflicting. We hypothesize that preventive dietary recommendations can help in the context of both chronic cancer treatment efficacy and the avoidance of development of secondary malignancies, as well as in the context of protection from the acute stress of surgery. In this perspective review, we will discuss the latest findings on the potential role of short-term dietary restriction in cancer treatment and improvement of surgical outcome. Copyright © 2017.

    Full Text Available Background/Aims: Age-related cerebrovascular dysfunction contributes to stroke, cerebral amyloid angiopathy, cognitive decline and neurodegenerative diseases. One pathogenic mechanism underlying this effect is increased oxidative stress. Up-regulation of mitochondrial uncoupling protein 2 (UCP2 plays a crucial role in regulating reactive oxygen species (ROS production. Dietary patterns are widely recognized as contributors to cardiovascular and cerebrovascular disease. In this study, we tested the hypothesis that dietary curcumin, which has an antioxidant effect, can improve aging-related cerebrovascular dysfunction via UCP2 up-regulation. Methods: The 24-month-old male rodents used in this study, including male Sprague Dawley (SD rats and UCP2 knockout (UCP2-/- and matched wild type mice, were given dietary curcumin (0.2%. The young control rodents were 6-month-old. Rodent cerebral artery vasorelaxation was detected by wire myograph. The AMPK/UCP2 pathway and p-eNOS in cerebrovascular and endothelial cells were observed by immunoblotting. Results: Dietary curcumin administration for one month remarkably restored the impaired cerebrovascular endothelium-dependent vasorelaxation in aging SD rats. In cerebral arteries from aging SD rats and cultured endothelial cells, curcumin promoted eNOS and AMPK phosphorylation, up-regulated UCP2 and reduced ROS production. These effects of curcumin were abolished by either AMPK or UCP2 inhibition. Chronic dietary curcumin significantly reduced ROS production and improved cerebrovascular endothelium-dependent relaxation in aging wild type mice but not in aging UCP2-/- mice. Conclusions: Curcumin improves aging-related cerebrovascular dysfunction via the AMPK/UCP2 pathway.

    Polycystic ovary syndrome (PCOS) is a common cause of ovulatory dysfunction impacting women of reproductive age. Obesity and insulin resistance are thought to potentiate disruptions in antral follicle development that result in chronic anovulation, and as such, have become important therapeutic targets of dietary interventions aimed at weight loss. Caloric restriction has been shown to promote sporadic ovulation in obese women with PCOS, but improvements have occurred across a wide range of patients and little has been garnered about the factors that distinguish responders from non-responders. Further, few studies have evaluated the likelihood for modest weight loss to restore normal ovulatory cyclicity in PCOS. Consensus regarding the impact of dietary intervention on ovulation has been limited by variability in the measures used to characterize and report ovulatory status across studies. In response, this review provides an assessment of the evidence surrounding the effectiveness of hypocaloric dietary intervention to normalize ovulatory function in PCOS. The impact of physiological versus methodological factors on the evaluation of ovulatory status is discussed and recommendations to strengthen future studies in this area are provided. Ultimately, further research is needed to understand the optimal dietary or lifestyle approaches that promote ovulation and sustained improvements in reproductive function in PCOS.

    Seventy percent of Mexican households experience some level of food insecurity (FI). Studies have shown positive associations between FI and poor dietary quality. As far as it is known, this is the first time the Healthy Eating Index (HEI-2010) has been used to assess dietary quality of children and adolescents in Mexico, and to examine if FI is related to it. The objective of this research is to assess dietary quality and its association with FI among Mexican children and adolescents from a nationally representative cross-sectional sample. We analyzed data from 4635 2-19-year-old Mexican children and adolescents participating in the Mexican National Health and Nutrition Survey (Ensanut 2012). FI was measured using the Latin American and Caribbean Household Food Security Scale (ELCSA) and dietary quality with the HEI-2010. We examined the association between FI and dietary quality using multivariate linear regressions. Dietary quality was worst as FI became more severe among children and adolescents compared with their counterparts living in households with food security. Specifically, FI had a negative association with fruits, vegetables, and protein foods, and a positive association with refined grains consumption. Dairy intake was negatively associated with FI among older children and adolescents. Added sugars were not associated with FI, but intake was excessive across the population at 15% of total daily energy intake. Decreasing FI may help improve dietary quality of Mexican children and adolescents. © 2016 John Wiley & Sons Ltd.

    Full Text Available Drought is the major abiotic stress factor that limits rice production worldwide. To evaluate the osmotic stress responses in rice varieties under drought condition, a total of 42 high-yielding rice varieties were collected from various research stations of Kerala Agricultural University in India. The experimental setup comprises of initial hydroponic treatments at different osmotic potentials, artificially induced by desired strengths of polyethylene glycol (PEG6000, and followed by the pot planted experiments in the rain-out-zone. The activities of antioxidant enzymes, relative water content, cell membrane stability, photosynthetic pigments, proline content, along with plant growth parameters of the varieties under drought condition were evaluated. Moreover, the standard scores of these rice varieties were assessed under stress and recovery conditions based on the scoring scale of the Standard Evaluation System for rice. Among the 42 rice varieties, we identified 2 rice varieties, Swarnaprabha and Kattamodan, with less leaf rolling, better drought recovery ability as well as relative water content, increased membrane stability index, osmolyte accumulation, and antioxidant enzyme activities pointed towards their degree of tolerance to drought stress. The positive adaptive responses of these rice varieties towards drought stress can be used in the genetic improvement of rice drought resistance breeding program.

    More kidney protective strategies are needed to reduce the burden of complete kidney failure from chronic kidney disease (CKD). Clinicians sometimes use protein restriction as kidney protection despite its demonstrated lack of effectiveness in the only large-scale study. Small-scale studies support that dietary acid reduction is kidney-protective, including when done with base-inducing foods like fruits and vegetables. We review these studies in light of current kidney-protective recommendations. Animal models of CKD show that acid-inducing dietary protein exacerbates and base-inducing protein ameliorates nephropathy progression, and that increased intake of acid-inducing but not base-inducing dietary protein exacerbates progression. Clinical studies show that dietary acid reduction with Na-based alkali reduces kidney injury and slows nephropathy progression in patients with CKD and reduced glomerular filtration rate (GFR); base-inducing fruits and vegetables reduce kidney injury in patients with reduced GFR; and base-inducing fruits and vegetables improve metabolic acidosis in CKD. Protein type rather than amount might more importantly affect nephropathy progression. Base-inducing foods might be another way to reduce dietary acid, a strategy shown in small studies to slow nephropathy progression. Further studies will determine if CKD patients should be given base-inducing food as part of their management.

    Full Text Available Strong evidence supports that dietary modifications may decrease incident type 2 diabetes mellitus (T2DM. Numerous diabetes risk models/scores have been developed, but most do not rely specifically on dietary variables or do not fully capture the overall dietary pattern. We prospectively assessed the association of a dietary-based diabetes-risk score (DDS, which integrates optimal food patterns, with the risk of developing T2DM in the SUN ("Seguimiento Universidad de Navarra" longitudinal study.We assessed 17,292 participants initially free of diabetes, followed-up for a mean of 9.2 years. A validated 136-item FFQ was administered at baseline. Taking into account previous literature, the DDS positively weighted vegetables, fruit, whole cereals, nuts, coffee, low-fat dairy, fiber, PUFA, and alcohol in moderate amounts; while it negatively weighted red meat, processed meats and sugar-sweetened beverages. Energy-adjusted quintiles of each item (with exception of moderate alcohol consumption that received either 0 or 5 points were used to build the DDS (maximum: 60 points. Incident T2DM was confirmed through additional detailed questionnaires and review of medical records of participants. We used Cox proportional hazards models adjusted for socio-demographic and anthropometric parameters, health-related habits, and clinical variables to estimate hazard ratios (HR of T2DM.We observed 143 T2DM confirmed cases during follow-up. Better baseline conformity with the DDS was associated with lower incidence of T2DM (multivariable-adjusted HR for intermediate (25-39 points vs. low (11-24 category 0.43 [95% confidence interval (CI 0.21, 0.89]; and for high (40-60 vs. low category 0.32 [95% CI: 0.14, 0.69]; p for linear trend: 0.019.The DDS, a simple score exclusively based on dietary components, showed a strong inverse association with incident T2DM. This score may be applicable in clinical practice to improve dietary habits of subjects at high risk of T2DM

    The school canteen provides a substantial proportion of the daily nutritional intake for many children. There are nutritional standards for school meals, however, it is still difficult to assess the dietary quality. To design a questionnaire for assessing the dietary quality of school meals, quickly and easily. A dietary questionnaire (COMES) was designed on the basis of the current recommendations. COMES consist of 15 items related to the food-frequency and to other characteristics of school meals. Then, a longitudinal prospective study was performed in order to analyze, with COMES, 36 school meals of 4 catering companies from Castilla y León during the academic years 2006-2007 to 2010-2011. Differences in dietary quality menus according to the management system of catering companies (in situ vs. transported) were analyzed by using the Mann-Whitney and the Kruskal-Wallis tests. The significance was reached at p culinary techniques were appropriate. No significant differences were found in the COMES score according to the management system (p=0,87), although catering system provides higher dietary quality. A new tool to assess quickly and easily the nutritional quality of school meals has been proposed. The assessment of the frequency intake of the most problematic foods for schoolchildren with this scale is much more demanding than the current recommendations. Even so, menus analyzed showed an acceptable quality in terms of variety of foods and culinary techniques, although milk frequency in the menus was excessive at the expense of fresh fruit. On the other hand, the transported system (i.e. catering, both hot and cold-holding) provides menus more consistent with the dietary recommendations. Copyright AULA MEDICA EDICIONES 2014.

    The beneficial effect of dietary fiber (DF) consumption has long been recognized. The global economy and open market trade policies have increased the availability of food products in Mexican markets, resulting in a wide variety of ready-to-eat commercial breakfast cereals classified as 'high fiber'. This research was aimed to evaluate the total dietary fiber contents, its fractions (soluble and insoluble) and β-glucan in 13 commercial 'high-fiber' breakfast cereals, as well as to evaluate their protein quality by rat bioassays. Commercial 'high-fiber' breakfast cereals had 7.42-39.82% insoluble dietary fiber, 2.53-12.85% soluble dietary fiber, and 0.45-4.96% β-glucan. These ready-to-eat commercial 'high-fiber' breakfast cereals differed significantly in their total dietary fiber, their soluble and insoluble DF fractions, and also in their β-glucan contents. When supplied as experimental diets, in 14-day rat feeding trials, the 'high-fiber' breakfast cereals showed an adverse effect on the % N digestibility but protein utilization, as measured as net protein ratio (NPR), was not significantly affected. The consumption of these commercial breakfast cereals, especially those made of oats as the basic ingredient, is highly recommended, since these products, being a concentrated source of dietary fiber, do not affect their protein quality.

    Athletes require sufficient nutrition knowledge and skills to enable appropriate selection and consumption of food and fluids to meet their health, body composition, and performance needs. This article reports the nutrition knowledge and dietary habits of male football (soccer) players in Australia. Players age 18 years and older were recruited from 1 A-League club (professional) and 4 National Premier League clubs (semiprofessional). No significant difference in general nutrition knowledge (GNK; 54.1% ± 13.4%; 56.8% ± 11.7%; M ± SD), t(71) = -0.91, p = .37, or sports nutrition knowledge (SNK; 56.9% ± 15.5%; 61.3% ± 15.9%), t(71) = -1.16, p = .25) were noted between professional (n = 29) and semiprofessional (n = 44) players. In general, players lacked knowledge in regard to food sources and types of fat. Although nutrition knowledge varied widely among players (24.6-82.8% correct responses), those who had recently studied nutrition answered significantly more items correctly than those who reported no recent formal nutrition education (62.6% ± 11.9%; 54.0% ± 11.4%), t(67) = 2.88, p = .005). Analysis of 3-day estimated food diaries revealed both professionals (n = 10) and semiprofessionals (n = 31) consumed on average less carbohydrate (3.5 ± 0.8 gC/kg; 3.9 ± 1.8 gC/kg) per day than football-specific recommendations (FIFA Medical and Assessment Research Centre [F-MARC]: 5-10 gC/kg). There was a moderate, positive correlation between SNK and carbohydrate intake (n = 41, ρ = 0.32, p = .04), indicating that players who exhibited greater SNK had higher carbohydrate intakes. On the basis of these findings, male football players in Australia would benefit from nutrition education targeting carbohydrate and fat in an attempt to improve nutrition knowledge and dietary practices.

    Breast cancer patients often show an interest in making dietary changes after diagnosis of breast cancer to improve their health condition and prevent cancer recurrence. The objective of the study was to determine changes in dietary intake 2 years after diagnosis among breast cancer patients. One hundred sixteen subjects were asked to complete a semiquantitative food frequency questionnaire, diet recalls, and dietary changes questionnaire to assess dietary intake before and after diagnosis. The information on sociodemographic background, cancer treatment history, and anthropometric indices was also collected. Seventy-two subjects considered diet as a contributing factor to breast cancer, and 67 subjects changed their dietary habits after breast cancer diagnosis. The reasons for changes in diet were physician and dietitian advice and desire to cure cancer. The sources of information were derived from their physician, mass media, and family members. Total energy, protein, total fat, fatty acids, and vitamin E intake were significantly decreased after diagnosis. Meanwhile, the intake of β-carotene and vitamin C increased significantly after diagnosis. The changes included reduction in red meat, seafood, noodles, and poultry intake. An increased consumption of fruits, vegetables, fish, low-fat milk, and soy products was observed. The subjects tended to lower high-fat foods intake and started to eat more fruits and vegetables. Breast cancer patients had changed to a healthier diet after breast cancer diagnosis, although the changes made were small. This will be helpful to dietitians in providing a better understanding of good eating habits that will maintain patients' health after breast cancer diagnosis.

    Poor appetite in older adults leads to sub-optimal food intake and increases the risk of undernutrition. The impact of poor appetite on food intake in older adults is unknown. The aim of this study was to examine the differences in food intake among older community-dwelling adults with different reported appetite levels. Cross-sectional analysis of data from a longitudinal prospective study. Health, aging, and body composition study performed in the USA. 2,597 community-dwelling adults aged 70-79. A semi-quantitative, interviewer-administered, 108-item food frequency questionnaire designed to estimate dietary intake. Poor appetite was defined as the report of a moderate, poor, or very poor appetite in the past month and was compared with good or very good appetite. The mean age of the study sample was 74.5 ± 2.8 years; 48.2% were men, 37.7% were black, and 21.8% reported a poor appetite. After adjustment for total energy intake and potential confounders (including biting/chewing problems), participants with a poor appetite had a significantly lower consumption of protein and dietary fiber, solid foods, protein rich foods, whole grains, fruits, and vegetables, but a higher consumption of dairy foods, fats, oils, sweets, and sodas compared to participants with very good appetite. In addition, they were less likely to report consumption of significant larger portion sizes. Older adults reporting a poor appetite showed a different dietary intake pattern compared to those with (very) good appetite. Better understanding of the specific dietary intake pattern related to a poor appetite in older adults can be used for nutrition interventions to enhance food intake, diet variety, and diet quality. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

    Maternal nutrition during gestation, especially dietary protein intake, is a key determinant in embryonic survival, growth, and development. Low maternal dietary protein intake can cause embryonic losses, intra-uterine growth restriction, and reduced postnatal growth due to a deficiency in specific amino acids that are important for cell metabolism and function. Of note, high maternal dietary protein intake can also result in intra-uterine growth restriction and embryonic death, due to amino acid excesses, as well as the toxicity of ammonia, homocysteine, and H 2 S that are generated from amino acid catabolism. Maternal protein nutrition has a pronounced impact on fetal programming and alters the expression of genes in the fetal genome. As a precursor to the synthesis of molecules (e.g. nitric oxide, polyamines, and creatine) with cell signaling and metabolic functions, L-arginine (Arg) is essential during pregnancy for growth and development of the conceptus. With inadequate maternal dietary protein intake, Arg and other important amino acids are deficient in mother and fetus. Dietary supplementation of Arg during gestation has been effective in improving embryonic survival and development of the conceptus in many species, including humans, pigs, sheep, mice, and rats. Both the balance among amino acids and their quantity are critical for healthy pregnancies and offspring. Impact statement This review aims at: highlighting adverse effects of elevated levels of ammonia in mother or fetus on embryonic/fetal survival, growth, and development; helping nutritionists and practitioners to understand the mechanisms whereby elevated levels of ammonia in mother or fetus results in embryonic/fetal death, growth restriction, and developmental abnormalities; and bringing, into the attention of nutritionists and practitioners, the problems of excess or inadequate dietary intake of protein or amino acids on pregnancy outcomes in animals and humans.

    Dietary factors are increasingly recognized to have an important role in triggering symptoms in a large proportion of patients with functional dyspepsia. Fatty foods seem to be the main culprits, but other foods (including carbohydrate-containing foods, milk and dairy products, citrus fruits, spicy foods, coffee and alcohol) have also been implicated. However, blind challenge tests do not provide consistent results. Moreover, although patients identify specific foods as triggers of their symptoms, these patients often do not seem to make behavioural adjustments in an attempt to improve symptoms; that is, any differences in dietary intake and lifestyle between patients and healthy individuals are small. Patients with functional dyspepsia exhibit mixed sensory-motor abnormalities, such as gastric hypersensitivity and impaired gastric accommodation of a meal. Nutrients, particularly fat, exacerbate these abnormalities and might thereby trigger postprandial symptoms. Cognitive factors, including anticipation related to previous negative experience with certain foods, might also have a role in triggering symptoms. Studies evaluating the potential beneficial effect of dietary interventions and changes in lifestyle are lacking, and this Review outlines a number of options that could be used as starting points for meaningful large-scale studies in the future.

    Since the passage of the Dietary Supplement Health and Education Act in 1994, the marketplace for dietary supplements has experienced dramatic growth. New products have redefined the entire marketplace, and new ingredients are introduced to consumers at lightning speed. As part of this act, laws were passed to ensure the safety of new dietary ingredients introduced into the United States marketplace. But more than 11 years later, these laws are frequently misunderstood, and more frequently ignored. This article reviews the regulatory landscape of new dietary ingredients and defines the issues manufacturers must contend with to legally market dietary supplements with new dietary ingredients in the U.S

    The Dietary Guidelines for Americans is the official nutrition policy statement for the United States. Government involvement in providing information on private behavior, such as food choice, is justified by the high cost of poor diets, as measured in medical expenses and lost productivity. The Guidelines are intended to provide an up-to-date, consistent information base for federal nutrition education and information efforts and food assistance program regulations. Through these policy mechanisms, the Guidelines are assumed to improve dietary behavior, and, ultimately, health. By law, the Dietary Guidelines for Americans must be updated every five years; however, there is no mandate for evaluation. Evaluation could provide useful information to assess the extent to which the Guidelines positively influence health and provide insights into reasons for their successes and limitations. However, evaluation would also present considerable challenges. This paper discusses the critical data and methodological needs for improving evaluation of the Dietary Guidelines for Americans.

    Full Text Available The aim of this study was to determine the prevalence of usage and the knowledge and attitudes towards dietary supplements among medical sciences and nonmedical sciences students from Croatia. The study was conducted based on a questionnaire about dietary supplement usage, knowledge and attitudes. The prevalence of dietary supplement use, among 910 university students was 30.5%. The most-used dietary supplements were vitamins (18.0% in medical sciences students and 9.8% in non-medical sciences students. For all students, the internet (66.1% was the most common source of information, followed by healthcare professionals (33.2%. The most common reason for taking dietary supplements was to maintain good health (26.4%. Use of the internet rather than health professionals as a trusted information source should be revised among this young population. Supplement intake was significantly associated with body mass index (BMI (p = 0.016 and physical activity (p = 0.050. Students with normal BMI (61.5% and the most physically active students (37.7% took significantly more dietary supplements. Results of this study could help medicine faculties to improve their curriculum and support the development of public health messages aimed at wise and safe use of dietary supplements.

    Full Text Available Introduction: Though nutrition is a key input to blood formation, little is known about the extent maternal dietary quality contributes to the haematological status of pregnant women in Northern Region of Ghana. Objective: The aim of this study was to assess the independent contribution of dietary diversity to haematological status of pregnant women whilst controlling for potential confounding factors including malarial infection. Methods: A cross-sectional study design was used on a sample of 307 pregnant women in their third trimester. A structured questionnaire was used to collect socio-demographic characteristics, obstetric and dietary data related to anaemia. Overall dietary quality was assessed using the dietary diversity score. Haemoglobin concentration (Hb was measured using portable HemoCueR Hb 301 system. Predictors of anaemia were estimated using multiple linear regression analysis. Results: The mean Hb was 10.8±1.4 g/dl and prevalence of anaemia (Hb < 11.0 g/dl was 46.3 %. High dietary diversity score [Beta coefficient (β, = 0.141 p < 0.001], multi-gravidity (β=0.205 and high composite score for ANC content (β= 0.201 were associated with a decreased risk of anaemia in the third trimester of pregnancy. Conclusion: The findings suggest the need to strengthen interventions that focus on improving the consumption of diversified foods particularly during pregnancy.

    Full Text Available Supplementation with nitrate (NO3−-rich beetroot juice has been shown to improve exercise performance and cardiovascular (CV responses, due to an increased nitric oxide (NO availability. However, it is unclear whether these benefits are greater in older adults who have an age-related decrease in NO and higher risk of disease. This systematic review examines 12 randomised, crossover, control trials, investigating food-based NO3− supplementation in older adults and its potential benefits on physiological and cognitive performances, and CV, cerebrovascular and metabolic health. Four studies found improvements in physiological performance (time to exhaustion following dietary NO3− supplementation in older adults. Benefits on cognitive performance were unclear. Six studies reported improvements in CV health (blood pressure and blood flow, while six found no improvement. One study showed improvements in cerebrovascular health and two found no improvement in metabolic health. The current literature indicates positive effects of dietary NO3− supplementation in older adults on physiological performance, with some evidence indicating benefits on cardiovascular and cerebrovascular health. Effects on cognitive performance were mixed and studies on metabolic health indicated no benefit. However, there has been limited research conducted on the effects of dietary NO3− supplementation in older adults, thus, further study, utilising a randomised, double-blind, control trial design, is warranted.

    Full Text Available Background: In most countries worldwide, hypertension is considered as an important problem. Moreover, an increasing trend in the prevalence and incidence has been reported in most countries. This increasing trend requires an innovative approach to improve the lifestyle modification of hypertensive sufferers including their dietary behaviors. Objective: This developmental research aims to develop a program for improving the dietary behaviors of community dwellers with hypertension. Method: The process of this program development includes a literature review related to the self-management programs for hypertension, and dietary behavior outcomes, expert validation, and pilot testing. Result: The setting, strategies, duration, and outcome measurement from the literature review were taken into consideration to develop the new program. The newly developed group-based self-management program consists of: 1 the sharing and reflecting of individual current dietary behavior, 2 group educational session, 3 individual comparison of behavior and reflection of obstacles, 4 individual goal setting, and 5 follow up. In the educational session, the DASH eating plan is used as the reference as it is commonly used in studies about diet for hypertension. Key words: hypertension, self-management, group based program, dietary behaviors.

    Basic research has shown that increasing variety increases energy intake, and repeated consumption of the same food increases habituation to those foods and reduces consumption. Twenty-four families with overweight/obese 8-12 year-old children and overweight/obese parents were randomly assigned to 6months of usual family based treatment (FBT) or FBT plus reduced variety of high energy-dense foods (FBT+Variety). Intention to treat mixed model ANOVA showed between group differences in child percent overweight (FBT+Variety-15.4% vs. FBT-8.9%, p=0.017) and parent BMI (FBT+Variety-3.7kg/m(2) vs. FBT-2.3kg/m(2); p=0.017). Positive relationships were observed between child zBMI and parent BMI changes (r=0.51, p=0.018), and between reductions in food variety of high energy-dense foods and reductions in child zBMI (r=0.54, p=0.02) and parent BMI (r=0.45, p=0.08). These pilot data suggest that reducing the variety of high energy dense foods and repeating meals within the context of FBT resulted in improved child and parent weight changes at six months. This represents easy to implement changes that reduce choice and may reduce response burden on families. Reducing variety may be a complement to standard FBT that enhances weight loss. Long term studies are needed to assess maintenance of these changes. Copyright © 2015 Elsevier Ltd. All rights reserved.

    2013-01-01

    Toric varieties associated with distributive lattices arise as a fibre of a flat degeneration of a Schubert variety in a minuscule. The singular locus of these varieties has been studied by various authors. In this article we prove that the number of diamonds incident on a lattice point $\\a$ in a product of chain lattices is more than or equal to the codimension of the lattice. Using this we also show that the lattice varieties associated with product of chain lattices is smooth.

    A strawberry isn't just a strawberry. Some are sweeter than others, more fragrant and juicier. It is therefore a difficult task to develop a strawberry that tastes like in childhood memories of endless sunny days, and which also is suitablefor the distribution system of today. But new varieties...... are on their way. And this time consumers have participated in the development process. The new strawberry varieties are the result of extensive product development in the research project 'Better Danish strawberries' in which the Danish Institute of Agricultural Science, Danish Fruit Growers' Association......, the Danish Veterinary and Food Administration and MAPP participated. Danish strawberry growers initiated the project and the purpose is to assure the quality of strawberries and to improve the distribution and sale. In order to get consumers to evaluate both new and existing varieties the MAPP Centre carried...

    conduct interventions for health promotion and disease prevention to ameliorate chronic risk factors for disease, such as for cardiovascular disease (CVD). Likewise, nutrient-dense, plant-rich (NDPR) dietary patterns have been shown to be effective at preventing and improving chronic-disease conditions, including CVD. Objective • The study's aim was to determine the feasibility and effectiveness of an NDPR dietary intervention for worksites to lower CVD risk factors. Design • The study was a 6-wk pilot intervention using a pretest and posttest design. The intervention was conducted at the Northern Arizona University (Flagstaff, AZ, USA) and sponsored by its Employee Assistance and Wellness Department. Participants • Participants were 35 employees with body mass indexes (BMIs) >25 kg/m2 who were ready and willing to make a lifestyle change, who were not currently participating in a weight loss program, and who were not taking any medications that could increase medical risk or had weight loss as a primary side effect. The average age of participants was 42.57 y; 91.4% were female, and 80% were Caucasian. Intervention • The intervention used a dietary protocol consisting of the daily consumption of greens, beans, legumes, and a variety of other vegetables, as well as fresh or frozen whole fruits, nuts, seeds, and whole grains. Participants were encouraged to minimize the consumption of refined grains, vegetable oils, processed foods, and animal products. Outcome Measures • The study measured serum lipids, height, weight, waist and hip circumference, waist-to-hip ratio, and blood pressure. Results • Based on paired-sample t tests and Wilcoxon signed-ranks test with a maximum level of P = .05, the intervention resulted in significant changes in weight, BMI, waist and hip measurements, high-density lipoproteins, low-density lipoproteins, and estimated average glucose. Conclusions • The findings favorably revealed that an NDPR dietary intervention that was

    The development of hull-less (naked) barley genotypes with the ability to grow under stressed environmental conditions becomes essential to increase the national production of the crop to supplement wheat production for bread making , which in turn will decrease our imports of wheat grains and flour. Thus, a selection breeding program was conducted to enhancement salt tolerance of the two local hull-less barley varieties Giza 129 and Giza 131. Grains of the both genotypes were exposed to gamma rays at doses of 0.0, 250 Gy and 350 Gy aiming to create genetic variability and selection within the induced variation. Phenotypic correlation coefficients between yield and its components for M2 populations indicated the possibility of using number of spikes/plant, biological yield/plant and harvest index as a selection criterion to pick out high yielding variants with improving tolerance to salt stress. On this basis, a considerable number of plants were selected and carried forward to the next generation to raise M3 progenies. The obtained results indicated that means of grain yield/plant for Giza 129 progenies derived from 250 and 350 Gy mutagenic treatments located between 10.37 gram and 13.90 gram for the former treatment and between 9.81 gram to 13.84 gram for the latter one compared to 8.01 gram for the average of the superior control populations. On the other hand, Averages of grain yield for Giza 131 progenies ranged from 11.10 gram to 14.17 gram (250 Gy treatment) and from 11.32 gram to 13.50 gram (350 Gy treatment) vs.8.92 gram for the better untreated control plants. Results also revealed that 250 Gy mutagenic treatment was superior to 350 Gy for improving yield potentiality of the materials at hand under salinity stressed conditions

    Several compounds of pharmaceutical importance from a variety of chemical families, for example chlorpromazine and clomipramine, have been found to form charge-transfer complexes with iodine. We have investigated the influence of dietary iodine on thyroid-gland dysfunction induced by clomipramine, chlorpromazine or 2-thiazoline-2-thiol. We suggest that iodine is partly diverted from its metabolic pathway by complexation with drugs, and so the urinary concentration of iodide is increased. Both chlorpromazine and clomipramine, at doses which do not inhibit thyroperoxidase, enhanced urinary iodine excretion when dietary iodine was restricted (3.944+/-0.96 microg/day for chlorpromazine-tested rats, 3.43+/-1.33 microg/day for clomipramine-tested rats, compared with 2.34+/-0.11 microg/day in control rats). Concurrently, these pharmaceutical compounds increased the level of free thyroid-stimulating hormone (TSH) in comparison with controls and induced histological modifications in, and enlargement of, the thyroid gland. We have demonstrated that drug-induced loss of iodine in the urine was associated with antithyroid action when iodine intake was limited.

    Clearance of fibrin and associated inflammatory cytokines by tissue-type plasminogen activator (t-PA) is related to improved regeneration in neurological disorder. The biological activity of fermented soybean (natto) is very similar to that of t-PA. We investigated the effect of the dietary supplement of natto on peripheral nerve regeneration. The peripheral nerve injury was produced by crushing the left sciatic nerve with a vessel clamp in Sprague-Dawley rats. The injured animals were fed orally either with saline or natto (16 mg/day) for seven consecutive days after injury. Increased functional outcome such as sciatic nerve functional index, angle of ankle, compound muscle action potential and conduction latency were observed in natto-treated group. Histological examination demonstrated that natto treatment improved injury-induced vacuole formation, S-100 and vessel immunoreactivities and axon loss. Oral intake of natto prolonged prothrombin time and reduced fibrinogen but did not change activated partial thromboplastin time and bleeding time. Furthermore, natto decreased injury-induced fibrin deposition, indicating a tolerant fibrinolytic activity. The treatment of natto significantly improved injury-induced disruption of blood-nerve barrier and loss of matrix component such as laminin and fibronectin. Sciatic nerve crush injury induced elevation of tumor necrosis factor alpha (TNF-alpha) production and caused apoptosis. The increased production of TNF-alpha and apoptosis were attenuated by natto treatment. These findings indicate that oral intake of natto has the potential to augment regeneration in peripheral nerve injury, possibly mediated by the clearance of fibrin and decreased production of TNF-alpha.

    Insight into the role of acculturation in dietary patterns is important to inform the development of nutrition programmes that target ethnic minority groups. Therefore, the present study aimed to investigate how the adherence to dietary patterns within an ethnic minority population in the Netherlands varies by acculturation level compared with the host population. Cross-sectional study using data of the HELIUS study. Dietary patterns were assessed with an ethnic-specific FFQ. Acculturation was operationalized using unidimensional proxies (residence duration, age at migration and generation status) as well as on the basis of the bidimensional perspective, defined by four distinct acculturation strategies: assimilation, integration, separation and marginalization. Amsterdam, the Netherlands. Participants of Dutch (n 1370) and Surinamese (n 1727) origin. Three dietary patterns were identified: (i) 'noodle/rice dishes and white meat' (traditional Surinamese pattern); (ii) 'red meat, snacks and sweets'; and (iii) 'vegetables, fruit and nuts'. Surinamese-origin respondents adhered more to the traditional Surinamese pattern than the other dietary patterns. Neither the unidimensional proxies nor the bidimensional acculturation strategies demonstrated consistent associations with dietary patterns. The lack of consistent association between acculturation and dietary patterns in the present study indicates that dietary patterns are quite robust. Understanding the continued adherence to traditional dietary patterns when developing dietary interventions in ethnic minority groups is warranted.

    This is the first of five review articles investigating dietary supplements (DS; includes herbs) that now exceed over 50,000 in the Office of Dietary Supplement's "Dietary Supplement Label Database." Four review articles follow summarizing published medical case reports of DS related to liver toxicity, kidney toxicity, heart toxicity, and cancer. The most popular DS were vitamin or mineral supplements (43%) followed by specialty supplements (20%), botanicals (20%; herbs), and sports supplements (16%). The 2013 Annual Report of the American Association of Poison Control Centers revealed 1692 fatalities due to drugs, and zero deaths due to DS. Less than 1 percent of Americans experience adverse events related to DS, and the majority was classified as minor, with many of these related to caffeine, yohimbe, or other stimulant ingredients. The number one adulterant in DS is drugs, followed by New Dietary Ingredients (NDI) not submitted to the FDA - both are illegal and not DS, but rather "tainted products marketed as dietary supplements." The three main categories of DS prone to medical problems are those for sexual enhancement, weight loss, and sports performance/body building. DS are regulated in the U.S. by several federal agencies with overlapping jurisdiction - the Food and Drug Administration (FDA) and the Federal Trade Commission (FTC); enforced by the State Attorneys General Offices (AGO) and Department of Justice (DOJ); and monitored (not regulated) by the Centers for Disease Control and Prevention (CDC). The FDA can remove a DS from the market for phase IV post-marketing surveillance adverse event reports, adulteration (drugs, NDI, synthetic substances), contamination, misidentification, mislabeling or false claims, and not meeting good manufacturing practices (GMP). The FTC and state AGO can also enforce laws against deceptive marketing practices. Suggested improvements to current regulatory requirements are included along with online DS Toxic Tables in the

    Smith-Morris, Carolyn

    2016-10-01

    The term "traditional diet" is used variously in public health and nutrition literature to refer to a substantial variety of foodways. Yet it is difficult to draw generalities about dietary tradition for specific ethnic groups. Given the strong association between migration and dietary change, it is particularly important that dietary advice for migrants be both accurate and specific. In this article, I examine the cultural construct of "traditional foods" through mixed method research on diet and foodways among rural farmers in Guanajuato, MX and migrants from this community to other Mexican and U.S. destinations. Findings reveal first, that quantitatively salient terms may contain important variation, and second, that some "traditional" dietary items -like "refresco," "carne," and "agua" - may be used in nutritionally contradictory ways between clinicians and Mexican immigrant patients. Specifically, the term "traditional food" in nutritional advice for Mexican migrants may be intended to promote consumption of fresh produce or less meat; but it may also invoke other foods (e.g., meats or corn), inspire more regular consumption of formerly rare foods (e.g., meats, flavored waters), or set up financially impossible goals (e.g., leaner meats than can be afforded). Salience studies with ethnographic follow up in target populations can promote the most useful and accurate terms for dietary advice. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Full Text Available Dietary indices evaluate diet quality, usually based on current dietary guidelines. Indices can therefore contribute to our understanding of early-life obesity-risk dietary behaviours. Yet indices are commonly applied to dietary data collected by onerous methods (e.g., recalls or records. Short dietary assessment instruments are an attractive alternative to collect data from which to derive an index score. A systematic review of studies published before April 2013 was conducted to identify short (≤50 items tools that measure whole-of-diet intake of young children (birth-five years and are applicable to dietary indices, in particular screening obesogenic dietary behaviours. The search identified 3686 papers of which 16, reporting on 15 tools (n=7, infants and toddlers birth-24 months; n=8, preschoolers 2–5 years, met the inclusion criteria. Most tools were food frequency questionnaires (n=14, with one innovative dietary questionnaire identified. Seven were tested for validity or reliability, and one was tested for both. Six tools (n=2, infants and toddlers; n=4, preschoolers are applicable for use with current dietary indices, five of which screen obesogenic dietary behaviours. Given the limited number of brief, valid and reliable dietary assessment tools for young children to which an index can be applied, future short tool development is warranted, particularly for screening obesogenic dietary behaviours.

    Diet is considered an important factor for bone health, but is composed of a wide variety of foods containing complex combinations of nutrients. Therefore we investigated the relationship between dietary patterns and fall-related fractures in the elderly. We designed a population-based prospective survey of 1178 elderly people in Japan in 2002. Dietary intake was assessed with a 75-item food frequency questionnaire (FFQ), from which dietary patterns were created by factor analysis from 27 food groups. The frequency of fall-related fracture was investigated based on insurance claim records from 2002 until 2006. The relationship between the incidence of fall-related fracture and modifiable factors, including dietary patterns, were examined. The Cox proportional hazards regression model was used to examine the relationships between dietary patterns and incidence of fall-related fracture with adjustment for age, gender, Body Mass Index (BMI) and energy intake. Among 877 participants who agreed to a 4 year follow-up, 28 suffered from a fall-related fracture. Three dietary patterns were identified: mainly vegetable, mainly meat and mainly traditional Japanese. The moderately confirmed (see statistical methods) groups with a Meat pattern showed a reduced risk of fall-related fracture (Hazard ratio = 0.36, 95% CI = 0.13 - 0.94) after adjustment for age, gender, BMI and energy intake. The Vegetable pattern showed a significant risk increase (Hazard ratio = 2.67, 95% CI = 1.03 - 6.90) after adjustment for age, gender and BMI. The Traditional Japanese pattern had no relationship to the risk of fall-related fracture. The results of this study have the potential to reduce fall-related fracture risk in elderly Japanese. The results should be interpreted in light of the overall low meat intake of the Japanese population.

    Full Text Available Abstract Background Diet is considered an important factor for bone health, but is composed of a wide variety of foods containing complex combinations of nutrients. Therefore we investigated the relationship between dietary patterns and fall-related fractures in the elderly. Methods We designed a population-based prospective survey of 1178 elderly people in Japan in 2002. Dietary intake was assessed with a 75-item food frequency questionnaire (FFQ, from which dietary patterns were created by factor analysis from 27 food groups. The frequency of fall-related fracture was investigated based on insurance claim records from 2002 until 2006. The relationship between the incidence of fall-related fracture and modifiable factors, including dietary patterns, were examined. The Cox proportional hazards regression model was used to examine the relationships between dietary patterns and incidence of fall-related fracture with adjustment for age, gender, Body Mass Index (BMI and energy intake. Results Among 877 participants who agreed to a 4 year follow-up, 28 suffered from a fall-related fracture. Three dietary patterns were identified: mainly vegetable, mainly meat and mainly traditional Japanese. The moderately confirmed (see statistical methods groups with a Meat pattern showed a reduced risk of fall-related fracture (Hazard ratio = 0.36, 95% CI = 0.13 - 0.94 after adjustment for age, gender, BMI and energy intake. The Vegetable pattern showed a significant risk increase (Hazard ratio = 2.67, 95% CI = 1.03 - 6.90 after adjustment for age, gender and BMI. The Traditional Japanese pattern had no relationship to the risk of fall-related fracture. Conclusions The results of this study have the potential to reduce fall-related fracture risk in elderly Japanese. The results should be interpreted in light of the overall low meat intake of the Japanese population.

    Peptic ulcer disease is a multifactorial and complex disease involving gastric and duodenal ulcers. Despite medical advances, the management of peptic ulcer and its complications remains a challenge, with high morbidity and death rates for the disease. An accumulating body of evidence suggests that, among a broad reach of natural molecules, dietary polyphenols with multiple biological mechanisms of action play a pivotal part in the management of gastric and duodenal ulcers. The current review confirmed that dietary polyphenols possess protective and therapeutic potential in peptic ulcer mediated by: improving cytoprotection, re-epithelialization, neovascularization, and angiogenesis; up-regulating tissue growth factors and prostaglandins; down-regulating anti-angiogenic factors; enhancing endothelial nitric oxide synthase-derived NO; suppressing oxidative mucosal damage; amplifying antioxidant performance, antacid, and anti-secretory activity; increasing endogenous mucosal defensive agents; and blocking Helicobacter pylori colonization associated gastric morphological changes and gastroduodenal inflammation and ulceration. In addition, anti-inflammatory activity due to down-regulation of proinflammatory cytokines and cellular and intercellular adhesion agents, suppressing leukocyte-endothelium interaction, inhibiting nuclear signaling pathways of inflammatory process, and modulating intracellular transduction and transcription pathways have key roles in the anti-ulcer action of dietary polyphenols. In conclusion, administration of a significant amount of dietary polyphenols in the human diet or as part of dietary supplementation along with conventional treatment can result in perfect security and treatment of peptic ulcer. Further well-designed preclinical and clinical tests are recommended in order to recognize higher levels of evidence for the confirmation of bioefficacy and safety of dietary polyphenols in the management of peptic ulcer.

    A 9-week study was conducted to compare dietary corn starch (CS) or tapioca starch (TS), with or without being pre-gelatinized (PG), on the growth, feeding efficiencies, plasma and muscle biochemistry, intestinal short chain fatty acids (SCFA), and liver glycogen of triplicate groups of 20 red hybrid tilapia (Orecohromis sp.). Various pellet characteristics were evaluated, along with their surface and cross sectional microstructure. The PG diets had significantly higher water stability, bulk density, and protein solubility, along with a smoother surface. Tilapia fed the TS diet had lower growth than had all other tilapia, but were significantly improved when diet was pre-gelatinized. In the PG treatments, intestinal SCFA significantly decreased while plasma glucose, cholesterol and triglycerides, as well as liver glycogen, significantly increased. Fish fed the CS diet had significantly more long chain polyunsaturated fatty acid than had those fed by other treatments. Pre-gelatinization may improve fish productivity and offer greater flexibility during aquafeed production. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The aim of this study was to investigate how dietary supplementation of tea polyphenols (TP) and tea catechins (TC) affect laying performance, albumen quality, ovomucin composition, and magnum morphology of laying hens in the late phase of production. Two hundred seventy Hy-Line Brown laying hens (64 wk old) were assigned to a basal diet (the control), the basal diet supplemented with 200 mg/kg tea polyphenols (TP200) or 200 mg/kg tea catechins (TC200). Each treatment had 6 replicates with 15 hens each. The feeding trial lasted 10 wks. Over the course of the trial, dietary supplementation with TP200 significantly increased the egg production (EP) and improved the feed conversion ratio (FCR) in wk 6 to 10 and wk 1 to 10 (P hens fed TP200 were higher than those of hens fed the control diet at wks 8 and 10 (P 0.05). The SDS-PAGE analysis indicated that bands of the ovomucin fractions in the TP200 group had the highest intensity compared with those of the control and TC200 groups. Compared with the control, there was a significant increase in protein sulfhydryl (SH) content of the albumen in the TP200 group at the end of experiment, while a significant decrease in protein carbonyl content and protein surface hydrophobicity (P hens. In addition, TP rather than TC could improve the health status of the magnum for aged layers.

    Full Text Available Background/Aims: Colorectal cancer (CRC is now a major public health problem with heavy morbidity and mortality in rural Africans despite the lingering dietary fiber-rich foodstuffs consumption. Studies have shown that increased intake of dietary fiber which contribute to low fecal pH and also influences the activity of intestinal microbiota, is associated with a lowered risk for CRC. However, whether or not the apparent high dietary fiber consumption by Africans do not longer protects against CRC risk is unknown. This study evaluated dietary fiber intake, fecal fiber components and pH levels in CRC patients. Methods: Thirty-five subjects (CRC=21, control=14, mean age 45 years were recruited for the study. A truncated food frequency questionnaire and modified Goering and Van Soest procedures were used. Results: We found that all subjects consumed variety of dietary fiber-rich foodstuffs. There is slight preponderance in consumption of dietary fiber by the control group than the CRC patients. We also found a significant difference in the mean fecal neutral detergent fiber, acid detergent fiber, hemicellulose, cellulose and lignin contents from the CRC patients compared to the controls (P<0.05. The CRC patients had significantly more fecal pH level than the matched apparently healthy controls (P=0.017. Conclusions: The identified differences in the fecal fiber components and stool pH levels between the 2 groups may relate to CRC incidence and mortality in rural Africans. There is crucial need for more hypothesis-driven research with adequate funding on the cumulative preventive role of dietary fiber-rich foodstuffs against colorectal cancer in rural Africans “today.”

    Children in the United States fall far short of meeting federal dietary recommendations. The unhealthy diets common amongst young children are of crucial public health concern, given that they can inhibit healthy development and are predictive of chronic diseases in adulthood. Research investigating behaviors that are related to dietary habits is crucial to allow a better understanding of the causes of unhealthy dietary practices. Involvement in food preparation is known to be associated with healthy dietary behaviors in school-aged children, but little is known about these behaviors and their correlates in younger children. The present study sought to examine the influences and correlates of involvement in family food preparation in children at ages three and four. Parents of preschool aged children (n = 497) completed surveys including information about demographic background, their children's family food involvement, dietary intake, mealtime routines, and problematic eating behaviors. Data were collected when children were three (wave one of the survey) and four years of age (wave two). Findings from this study indicate that family food involvement at age three is predictive of healthier dietary intake at age four (increased consumption of fruits and vegetables, decreased consumption of fast food). These findings indicate that family food involvement is predictive of healthier dietary behaviors in young children, and that outreach efforts focused on family food involvement in early childhood may improve children's dietary habits.

    This study sought to determine the simultaneous effect of immediate eating environment variables; portion size, plate size, proximity to food, variety of food, side serves of salad/vegetables and presence of distraction on dietary energy intake (EI), of a reported evening meal, in the participants' real world setting. A retrospective computer assisted telephone interview collected data on ten immediate eating environment variables, covariates and a 24-hour dietary recall of EI at an evening meal. Multiple regression analysis was conducted to determine relationships of these variables with EI. Significant (Phunger score also had a positive relationship with EI (β=0.190), explaining 17.5% of the variance. This study provides evidence that some immediate food environment variables at an evening eating occasion are associated with EI. Findings suggest there are several strategies that people could implement to assist in controlling their EI and help address over consumption. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Virtually all chronic liver injuries result in the activation of hepatic stellate cells (HSCs). In their activated state, these cells are the main collagen-producing cells implicated in liver fibrosis. Capsaicin (CPS), the active compound of chili peppers, can modulate the activation and migration of HSCs in vitro. Here, we evaluated the potential protective and prophylactic effects of CPS related to cholestatic and hepatotoxic-induced liver fibrosis and its possible underlying mechanism of action. Male Balb/c mice received dietary CPS after 3 days of bile duct ligation (BDL) or before and during carbon tetrachloride (CCl4 ) injections. Mice receiving dietary CPS after BDL had a significant improvement of liver fibrosis accompanied by a decrease in collagen deposition and downregulation of activation markers in isolated HSCs. In the CCl4 model, dietary CPS inhibited the upregulation of profibrogenic markers. However, CPS could not attenuate the CCl4 -induced fibrosis when it was already established. Furthermore, in vitro CPS treatment inhibited the autophagic process during HSC activation. Dietary CPS has potential benefits in the therapy of cholestatic liver fibrosis and in the prophylaxis of hepatotoxic-induced liver injury. © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    Dietary fat content (low versus high fat) may modulate the serum lipid-lowering effect of high-performance (HP)-inulin. This study investigated the effect of dietary HP-inulin on metabolism in rats fed a low- or high-fat diet. Rats were fed a diet of 5% fat with 5% cellulose or 5% HP-inulin (average degree of polymerization = 24) (low-fat diet) or of 20% fat with 5% cellulose or 5% HP-inulin (high-fat diet) for 28 days. Total, HDL, and non-HDL cholesterols, and triglyceride concentrations in the serum were measured along with total lipid content of liver and feces. Hepatic triglyceride and cholesterol, and fecal neutral and acidic sterol concentrations in total lipid were assessed. In addition, cecum SCFA levels and bacterial profiles were determined. The hypolipidemic effect of HP-inulin differed depending on dietary fat content (5% versus 20%). Specifically, 5% inulin instead of cellulose in a semi-purified diet significantly reduced serum lipid levels in rats fed a high-fat diet, which was strongly associated with increased total lipid and neutral sterol excretion. Dietary fat content modulates the hypolipidemic effect of dietary inulin. © 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

  16. Oxidative Stress and Dietary Fat Type in Relation to Periodontal Disease

    Full Text Available Oxidative stress is one of the main factors studied to explain the pathophysiological mechanisms of inflammatory conditions, such as periodontitis. In this respect, nutrition may be of great importance. Actually, research on nutrients’ effects on periodontal diseases has expanded to include those influencing the redox status, which correlates to the inflammatory process. Dietary fat or lipids are often blamed as the major source of excess energy. Consequently, when caloric intake exceeds energy expenditure, the resultant substrate-induced increase in citric acid cycle activity generates an excess of reactive oxygen species (ROS. In addition, dietary fatty acid intake influences in relative fatty acid composition of biological membranes determining its susceptibility to oxidative alterations. From this standpoint, here, we reviewed studies analyzing the dietary fat role in periodontal disease. Research data suggest that periodontal health could be achieved by main dietary strategies which include substitution of saturated fats with monounsaturated fatty acids (MUFA and polyunsaturated fatty acids (PUFA, particularly n-3 PUFA. Maybe in the future, we should analyze the diet and provide some advice to periodontitis patients to improve treatment outcomes.

    Competitive bodybuilders are well known for extreme physique traits and extremes in diet and training manipulation to optimize lean mass and achieve a low body fat. Although many of the dietary dogmas in bodybuilding lack scientific scrutiny, a number, including timing and dosing of high biological value proteins across the day, have more recently been confirmed as effective by empirical research studies. A more comprehensive understanding of the dietary intakes of bodybuilders has the potential to uncover other dietary approaches, deserving of scientific investigation, with application to the wider sporting, and potential health contexts, where manipulation of physique traits is desired. Our objective was to conduct a systematic review of dietary intake practices of competitive bodybuilders, evaluate the quality and currency of the existing literature, and identify research gaps to inform future studies. A systematic search of electronic databases was conducted from the earliest record until March 2014. The search combined permutations of the terms 'bodybuilding', 'dietary intake', and 'dietary supplement'. Included studies needed to report quantitative data (energy and macronutrients at a minimum) on habitual dietary intake of competitive bodybuilders. The 18 manuscripts meeting eligibility criteria reported on 385 participants (n = 62 women). Most studies were published in the 1980-1990s, with three published in the past 5 years. Study methodological quality was evaluated as poor. Energy intake ranged from 10 to 24 MJ/day for men and from 4 to 14 MJ/day for women. Protein intake ranged from 1.9 to 4.3 g/kg for men and from 0.8 to 2.8 g/kg for women. Intake of carbohydrate and fat was 6 months from competition) or immediate post-competition period and lowest during competition preparation (≤6 months from competition) or competition week. The most commonly reported dietary supplements were protein powders/liquids and amino acids. The studies failed to provide

    Micronutrient malnutrition affects the well-being of both adults and children. Dietary diversity score (DDS) is a useful evaluation index with a relatively well-developed guideline by FAO. It's meaningful to assess and predict inadequate micronutrient intakes using DDS in Chinese children, after ruling out the risk of obesity coming with more dietary diversity. Data for evaluation were extracted from the Nutrition Study of Preschool Children and School Children, which is a cross-sectional study covering 8 cities of China, including 1694 children in kindergartens and primary schools. This study applied DDS to Chinese children to test the validity for micronutrient inadequacy, and then explored the relationship between dietary diversity and obesity. It reveals that dietary diversity varied with age and place of residence; the older ones and the ones living in rural areas tend to have poorer dietary diversity. Another discovery is that DDS is positively correlated with indicators of micronutrient adequacy, with a score of 6-8 indicating the lowest risk of micronutrient inadequacy in different groups of children. In our study population, dietary diversity is not related with obesity. Dietary diversity score is a valid indicator to evaluate micronutrient inadequacy in Chinese children, though there is still room for improvement of the method. Besides, the relationship between increase of dietary diversity and risk of obesity should be treated circumspectly.

    Although an estimated 50% of adults in the United States consume dietary supplements, analytically substantiated data on their bioactive constituents are sparse. Several programs funded by the Office of Dietary Supplements (ODS) at the National Institutes of Health enhance dietary supplement database development and help to better describe the quantitative and qualitative contributions of dietary supplements to total dietary intakes. ODS, in collaboration with the United States Department of Agriculture, is developing a Dietary Supplement Ingredient Database (DSID) verified by chemical analysis. The products chosen initially for analytical verification are adult multivitamin-mineral supplements (MVMs). These products are widely used, analytical methods are available for determining key constituents, and a certified reference material is in development. Also MVMs have no standard scientific, regulatory, or marketplace definitions and have widely varying compositions, characteristics, and bioavailability. Furthermore, the extent to which actual amounts of vitamins and minerals in a product deviate from label values is not known. Ultimately, DSID will prove useful to professionals in permitting more accurate estimation of the contribution of dietary supplements to total dietary intakes of nutrients and better evaluation of the role of dietary supplements in promoting health and well-being. ODS is also collaborating with the National Center for Health Statistics to enhance the National Health and Nutrition Examination Survey dietary supplement label database. The newest ODS effort explores the feasibility and practicality of developing a database of all dietary supplement labels marketed in the US. This article describes these and supporting projects.

    Full Text Available Several early ripening pumpkin varieties adn hybrids with high yield and resistance to cold and diseases and high organoleptic properties were developed in Federal Scientific Vegetable Cencer. They are early, cold-resistant, yielding and resistant to a diseases and they have high taste and technological qualities of fruits. Most varieties of pumpkin need to fruit ripening to improve their taste. Lateripening varieties with long-term storage of fruits, until the end of November – early December, accumulate up to 10% of the amount of sugars. The timing of pumpering and storage of pumpkin fruits without loss of quality and taste indicators are individual for each variety and can vary greatly between each other. Gourds of a pumpkin of a dining room are shown as practically not requiring, and requiring in fruit ripening – from two weeks to two months. To a large extent, all varieties differ in terms of the shelf life of the fruit. Using these characteristics of varieties, even in the conditions of the Moscow region, you can create a continuous conveyor of consumption of pumpkin fruits. Recommendations are given on the timing of dosage and use of fruits of different varieties of pumpkin selection Federal Scientific Vegetable Center.

    Three mutant varieties, 16 hybrids of advanced generation, 6 recommended varieties and many local collections of rice in Bangladesh were screened for protein content. The 25 varieties or strains showed a variation of protein content between 8.9 - 11.7% and also wide ranges of variation in amylose content, starch-iodine-blue value and water absorption by grain. Amino acid compositions of some promising varieties were also investigated. 60 rice germplasms tested also showed a wide range of variation in protein content (6-13%) and variations of other seed characteristics. 3000 local collections showed a variation range of 5-13% protein content. Mutation breedings were carried out on chickpeas and lentils on a large scale. Dry seed was treated with 60 Co gamma ray and mutants were detected, selected, particularly for high protein content, and evaluated in M 2 -M 8 generations. Of the 10 selected mutant lines of each of the pulses, variations of various agronomic characters were observed. However, induced variation in protein content was only remarkable in chickpea. The most promising chickpea mutant showed 19% higher yield and 12% higher protein content than the mother variety, and was proposed to be released as a variety

    In this paper, we will show that a vanishing generalized concurrence of a separable state can be seen as an algebraic variety called the Segre variety. This variety defines a quadric space which gives a geometric picture of separable states. For pure, bi- and three-partite states the variety equals the generalized concurrence. Moreover, we generalize the Segre variety to a general multipartite state by relating to a quadric space defined by two-by-two subdeterminants

    Epidemiological studies have linked whole-grain cereal consumption to a reduced risk of developing several chronic diseases – coronary heart disease, arteriosclerosis, type-2 diabetes and colonic and breast cancer. The underlying physiological mechanisms behind the protective effects of whole......-grains, however, are unclear but is most likely assigned to a concerted action of dietary fiber (DF) and a wide variety of phytochemicals. The DF fraction of cereals consists of non-starch polysaccharides (NSP), resistant starch, oligosaccharides (mostly fructans) and the non-carbohydrate polyphenolic ether...... lignin. The main NSP in cereals are arabinoxylan (AX), mixed linkages β(1-3; 1-4)-glucan (β-glucan) and cellulose, which vary significantly according to the cereal species but also between different tissues of the grains. Rye, triticale, wheat and corn are rich in AX, whereas barley and oats contain...

    The Akaike Information Criterion (AIC) is a well-known tool for variable selection in multivariable modeling as well as a tool to help identify the optimal representation of explanatory variables. However, it has been discussed infrequently in the dental literature. The purpose of this paper is to demonstrate the use of AIC in determining the optimal representation of dietary variables in a longitudinal dental study. The Iowa Fluoride Study enrolled children at birth and dental examinations were conducted at ages 5, 9, 13, and 17. Decayed or filled surfaces (DFS) trend clusters were created based on age 13 DFS counts and age 13-17 DFS increments. Dietary intake data (water, milk, 100 percent-juice, and sugar sweetened beverages) were collected semiannually using a food frequency questionnaire. Multinomial logistic regression models were fit to predict DFS cluster membership (n=344). Multiple approaches could be used to represent the dietary data including averaging across all collected surveys or over different shorter time periods to capture age-specific trends or using the individual time points of dietary data. AIC helped identify the optimal representation. Averaging data for all four dietary variables for the whole period from age 9.0 to 17.0 provided a better representation in the multivariable full model (AIC=745.0) compared to other methods assessed in full models (AICs=750.6 for age 9 and 9-13 increment dietary measurements and AIC=762.3 for age 9, 13, and 17 individual measurements). The results illustrate that AIC can help researchers identify the optimal way to summarize information for inclusion in a statistical model. The method presented here can be used by researchers performing statistical modeling in dental research. This method provides an alternative approach for assessing the propriety of variable representation to significance-based procedures, which could potentially lead to improved research in the dental community. © 2017 American

    Rice occupies a major share in crop production in the Chotanagpur plateau of Bihar State. Uplands are roughly 40% in area where traditional low yielding rice, known as ''gora'' is cultivated as directly sown crop. Despite introduction of high yielding rice varieties, gora group of rices continue to prevail. It is therefore desired to increase the productivity level of the gora rice by mutation breeding. One such mutant known as ''gora mutant'' was obtained through gamma irradiation (10 kR) of variety Brown gora. The maturity of both parent and mutant remaining constant (ie. 100 days), there is some improvement in other characteristics like plant height, tillering capacity and kernel character. The parent being tall, shy in tillering and red bold kernel, the mutant has dwarfish characteristics, profuse tillering habit and white kernel with fine grains. The yielding capacity of mutant derivative is 30-40% higher than the parent Brown gora. This variety is in pre-release stage, and the farmers have taken great liking for it. (author)

    An unfavorable trend of increasing rates of colorectal cancer has been observed across modern societies. In general, dietary factors are understood to be responsible for up to 70% of the disease's incidence, though there are still many inconsistencies regarding the impact of specific dietary items. Among the dietary minerals, calcium intake may play a crucial role in the prevention. The purpose of this study was to assess the effect of intake of higher levels of dietary calcium on the risk of developing of colorectal cancer, and to evaluate dose dependent effect and to investigate possible effect modification. A hospital based case-control study of 1556 patients (703 histologically confirmed colon and rectal incident cases and 853 hospital-based controls) was performed between 2000-2012 in Krakow, Poland. The 148-item semi-quantitative Food Frequency Questionnaire to assess dietary habits and level of nutrients intake was used. Data regarding possible covariates was also collected. After adjustment for age, gender, education, consumption of fruits, raw and cooked vegetables, fish, and alcohol, as well as for intake of fiber, vitamin C, dietary iron, lifetime recreational physical activity, BMI, smoking status, and taking mineral supplements, an increase in the consumption of calcium was associated with the decrease of colon cancer risk (OR = 0.93, 95% CI: 0.89-0.98 for every 100 mg Ca/day increase). Subjects consumed >1000 mg/day showed 46% decrease of colon cancer risk (OR = 0.54, 95% CI: 0.35-0.83). The effect of dietary calcium was modified by dietary fiber (p for interaction =0.015). Finally, consistent decrease of colon cancer risk was observed across increasing levels of dietary calcium and fiber intake. These relationships were not proved for rectal cancer. The study confirmed the effect of high doses of dietary calcium against the risk of colon cancer development. This relationship was observed across different levels of dietary fiber, and the

    Full Text Available Introduction: The incidence of diabetes increases in Poland and all over the world. Diet is an integral element of diabetes therapy. The knowledge of dietary rules and compliance with them facilitates body mass reduction and improves metabolic parameters of the body thus preventing diabetes’ complications development. Aim: The aim of the study was to evaluate the knowledge of dietary rules among diabetic patients. Material and methods: The study included 50 patients with recognized diabetes  who were hospitalized in SPSK-4 hospital in Lublin from January to May, 2016. In the study the diagnostic survey was applied. Results: The knowledge of basic dietary rules in diabetes among the majority of surveyed diabetic patients (64% was unsatisfactory. The most significant deficit included lack of acquaintance with glycemic index and carbohydrate exchanges thus making it impossible to make use of them in preparing everyday meals. The knowledge of the surveyed patients depended on their educational status, place of residence and age. Unsatisfactory knowledge was found among 82% of patients  with primary education vs. 40% with higher education, in 80% with countryside residence vs. 53% residing in town and in 80% of patients aged 31-40  and 41-55 years vs. 50% aged 18-30. Conclusion: Dietary education is a necessary element of diabetes therapy. Educating patients about diabetic diet should be repeated regularly as even patients with long-standing diabetes history have unsatisfactory knowledge about the dietary rules. Preferably, educating should be individual and adjusted to patient’s age and education.

  11. The role of dietary creatine.

    The daily requirement of a 70-kg male for creatine is about 2 g; up to half of this may be obtained from a typical omnivorous diet, with the remainder being synthesized in the body Creatine is a carninutrient, which means that it is only available to adults via animal foodstuffs, principally skeletal muscle, or via supplements. Infants receive creatine in mother's milk or in milk-based formulas. Vegans and infants fed on soy-based formulas receive no dietary creatine. Plasma and muscle creatine levels are usually somewhat lower in vegetarians than in omnivores. Human intake of creatine was probably much higher in Paleolithic times than today; some groups with extreme diets, such as Greenland and Alaskan Inuit, ingest much more than is currently typical. Creatine is synthesized from three amino acids: arginine, glycine and methionine (as S-adenosylmethionine). Humans can synthesize sufficient creatine for normal function unless they have an inborn error in a creatine-synthetic enzyme or a problem with the supply of substrate amino acids. Carnivorous animals, such as lions and wolves, ingest much larger amounts of creatine than humans would. The gastrointestinal tract and the liver are exposed to dietary creatine in higher concentrations before it is assimilated by other tissues. In this regard, our observations that creatine supplementation can prevent hepatic steatosis (Deminice et al. J Nutr 141:1799-1804, 2011) in a rodent model may be a function of the route of dietary assimilation. Creatine supplementation has also been reported to improve the intestinal barrier function of the rodent suffering from inflammatory bowel disease.

    Full Text Available People with diabetes have accelerated arterial stiffening. The aim of this study was to determine the effect of increasing fruit, vegetable and dairy intake for 12 months on carotid femoral pulse wave velocity (cfPWV, augmentation index (AIx, and central blood pressure (cBP, compared to a usual diet control, in people with type 1 and type 2 diabetes. In a 12 months randomised controlled trial, cfPWV, AIx and cBP were measured every 3 months. The intervention group received dietary counselling to increase consumption of fruit (+1 serving/day; 150 g/day, vegetables (+2 servings/day; 150 g/day and dairy (+1 serving/day; 200–250 g/day at baseline, 1, 3, 6 and 9 months. The control group continued on their usual diet. One hundred and nine participants were randomised and 92 (intervention n = 45; control n = 47 completed. At 3 months, fruit (184 g/day; p = 0.001 and dairy (83 g/day; p = 0.037 intake increased in the intervention group compared with the control group but this increase was not maintained at 12 months. After adjustment for baseline measurements there was no time by treatment effect for central systolic or diastolic BP, AIx or cfPWV. A time effect existed for AIx which modestly increased over time. Peripheral diastolic BP and central pulse pressure were improved in the intervention group compared with the control group at 12 months. In the cohort with type 1 and type 2 diabetes, improving dietary quality by increasing consumption of fruit, vegetables and dairy did not improve cBP, AIx or cfPWV, compared with a control group continuing on their usual diet, after 12 months.

    The effect of dietary supplementation with N,N-dimethylglycine sodium salt (Na-DMG) was evaluated in a feeding trial with 1500 1-day-old broiler chicks (Cobb 500). DMG was supplemented at 0, 0.1, 0.2, 0.5 or 1 g Na-DMG/kg feed to a ration with either animal fat (chicken fat) or vegetal fat (soy oil) as main fat source. In the vegetal fat diets, production value was significantly linearly improved by supplementation with DMG up to 11%. Irrespective of dietary fat source, abdominal fat percentage was significantly linearly reduced up to 24% and meat yield tended to increase linearly with DMG level up to 4%. In the vegetal fat groups, DMG significantly lowered abdominal fat pad by up to 38% and tended to increase meat yield up to 6% at the highest dose. Fasted non-esterified fatty acid level significantly decreased with increasing DMG level up to 36% and thiobarbituric acid reactive species (TBARS) decreased with a statistical trend up to 46% at the highest dose. In vegetal fat diets, addition of DMG resulted in significant lower TBARS level by 56% at the highest dose. Finally, a significant quadratic effect on ascites heart index was present in the vegetal fat diets, with a minimal value at 0.5 g Na-DMG/kg. In conclusion, dietary supplementation with DMG may improve technical and slaughter performance, and may reduce oxidative stress and pulmonary hypertension, but the degree of effects is modulated by fatty acid profile of the diet. Herewith, effects are more pronounced in a diet rich in polyunsaturated fatty acids compared with a diet rich in saturated and monounsaturated fatty acids. © 2010 Blackwell Verlag GmbH.

    1. This experiment was conducted to evaluate the effects of dietary supplementation of resveratrol on laying performance, egg quality, egg yolk cholesterol and antioxidant enzyme activities of laying hens. 2. A total of 360 Beijing PINK-1 laying hens (60 weeks old) were randomly distributed among five dietary treatments, each of which included 6 replicates of 12 hens. Dietary treatments were basal diet supplemented with 0 (control), 0.5, 1.0, 2.0 and 4.0 g/kg diet resveratrol. The study lasted for 9 weeks including 1 week of adaptation and 8 weeks of the main experimental period. 3. The results indicated that dietary resveratrol significantly improved feed conversion ratios during 5-8 weeks and 1-8 weeks of the trial. Increasing dietary concentrations of the resveratrol linearly improved Haugh unit and albumen height of eggs. 4. The content of total cholesterol (TC), total triglyceride (TG), low density lipoprotein cholesterol (LDL-C), very low density lipoprotein cholesterol (VLDL-C) in serum and cholesterol in yolk was significantly decreased by dietary resveratrol, and there were significant linear correlations between these indexes and resveratrol supplemental levels. 5. Dietary resveratrol supplementation significantly improved serum Glutathione peroxidase (GSH-Px) enzyme activity and decreased serum malondialdehyde (MDA) content in groups with 2.0 and 4.0 g/kg resveratrol as compared to the control, respectively. However, supplementation of resveratrol did not affect the activity of serum superoxide dismutase (SOD). 6. It is concluded that resveratrol supplementation has a positive effect on performance, lipid-related traits and antioxidant activity of laying hens.

    In practice, nutrition recommendations vary widely for inpatient and discharge management of acute, uncomplicated diverticulitis. This systematic review aims to review the evidence and develop recommendations for dietary fibre modifications, either alone or alongside probiotics or antibiotics, versus any comparator in adults in any setting with or recently recovered from acute, uncomplicated diverticulitis. Intervention and observational studies in any language were located using four databases until March 2017. The Cochrane Risk of Bias tool and GRADE were used to evaluate the overall quality of the evidence and to develop recommendations. Eight studies were included. There was “very low” quality evidence for comparing a liberalised and restricted fibre diet for inpatient management to improve hospital length of stay, recovery, gastrointestinal symptoms and reoccurrence. There was “very low” quality of evidence for using a high dietary fibre diet as opposed to a standard or low dietary fibre diet following resolution of an acute episode, to improve reoccurrence and gastrointestinal symptoms. The results of this systematic review and GRADE assessment conditionally recommend the use of liberalised diets as opposed to dietary restrictions for adults with acute, uncomplicated diverticulitis. It also strongly recommends a high dietary fibre diet aligning with dietary guidelines, with or without dietary fibre supplementation, after the acute episode has resolved. PMID:29382074

    Nutrition is a major determinant of health throughout all stages of life and together with smoking is the most important risk factor for morbidity and mortality in the Asia Pacific Region. The workshop participants examined Dietary Guidelines and Food Guides that are in use in our region, together with additional materials from the World Health Organization, UNICEF and the World Cancer Research Foundation. The resulting set of guidelines is meant as a reminder of the main issues to be covered in a general public health education program. It may also be of value in reminding public health practitioners, educators, administrators, and policy makers of current nutrition issues. It may additionally be useful as a checklist of the issues to be considered in public health programs and regulations. The main areas of nutrition that are included in the Guidelines are eating a variety of foods, including vegetables, fruits, whole grain cereals, and nuts. Choose fish, poultry, and meats grown in a sustainable way. Appropriate growth, including avoiding obesity, and physical activity are important. Breastfeeding is the basis of infant nutrition and nutrition of mothers is an important public health measure. Negative factors in the Asian diet include salt, refined sugar, alcohol and fats. The APACPH Dietary Guidelines will need to be kept under review and modified to meet regional differences in food supply. The Guidelines will be useful as a checklist of the issues to be considered in public health programs, addressing both acute and chronic diseases.

    Estimating trends in dietary intake data is integral to informing national nutrition policy and monitoring progress towards dietary guidelines. Dietary intake of sugars is a controversial public health issue and guidance in relation to recommended intakes is particularly inconsistent. Published data relating to trends in sugars intake are relatively sparse. The purpose of the present review was to collate and review data from national nutrition surveys to examine changes and trends in dietary sugars intake. Only thirteen countries (all in the developed world) appear to report estimates of sugars intake from national nutrition surveys at more than one point in time. Definitions of dietary sugars that were used include 'total sugars', 'non-milk extrinsic sugars', 'added sugars', sucrose' and 'mono- and disaccharides'. This variability in terminology across countries meant that comparisons were limited to within countries. Hence trends in dietary sugars intake were examined by country for the whole population (where data permitted), and for specific or combined age and sex subpopulations. Findings indicate that in the majority of population comparisons, estimated dietary sugars intake is either stable or decreasing in both absolute (g/d) and relative (% energy) terms. An increase in sugars intake was observed in few countries and only in specific subpopulations. In conclusion, the findings from the present review suggest that, in the main, dietary sugars intake are decreasing or stable. A consistent approach to estimation of dietary sugars intake from national nutrition surveys is required if more valid estimates of changes in dietary sugars intakes are required in the future.

    The dental care setting is an appropriate place to deliver dietary assessment and advice as part of patient management. However, we do not know whether this is effective in changing dietary behaviour. To assess the effectiveness of one-to-one dietary interventions for all ages carried out in a dental care setting in changing dietary behaviour. The effectiveness of these interventions in the subsequent changing of oral and general health is also assessed. The following electronic databases were searched: the Cochrane Oral Health Group Trials Register (to 24 January 2012), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2012, Issue 1), MEDLINE via OVID (1950 to 24 January 2012), EMBASE via OVID (1980 to 24 January 2012), CINAHL via EBSCO (1982 to 24 January 2012), PsycINFO via OVID (1967 to 24 January 2012), and Web of Science (1945 to 12 April 2011). We also undertook an electronic search of key conference proceedings (IADR and ORCA between 2000 and 13 July 2011). Reference lists of relevant articles, thesis publications (Dissertations Abstracts Online 1861 to 2011) were searched. The authors of eligible trials were contacted to identify any unpublished work. Randomised controlled trials assessing the effectiveness of one-to-one dietary interventions delivered in a dental care setting. Abstract screening, eligibility screening and data extraction decisions were all carried out independently and in duplicate by two review authors. Consensus between the two opinions was achieved by discussion, or involvement of a third review author. Five studies met the criteria for inclusion in the review. Two of these were multi-intervention studies where the dietary intervention was one component of a wider programme of prevention, but where data on dietary behaviour change were reported. One of the single intervention studies was concerned with dental caries prevention. The other two concerned general health outcomes. There were no studies

    Full Text Available Introduction: Adolescents are considered to be a nutritionally vulnerable segment of the population. There is a greater need to look into the nutritional status of adolescents but unfortunately, precise estimates of their dietary intake, dietary practices as well as nutritional deficiencies have been the least explored area. The general objective for conducting this study was to assess the dietary pattern and nutritional deficiencies among adolescents. Materials and Methods: A cross-sectional study was conducted among adolescents in schools and colleges in the urban areas of Jhansi district in Uttar Pradesh. The study sample consisted of 400 school children in the age group of 10-19 years. Food consumption of the subjects was assessed using a 3-day food intake recall method. Results: Mean age of the adolescents was 14.16 years. More than half of the children studied had malnutrition (53.5%. Mean intake of calorie, protein, fat, iron, and vitamins A and C were lower than the Recommended Dietary Allowances (RDAs. The habitual dietary pattern indicated poor consumption of milk, liver, and leafy vegetables. In comparison to boys (31.5%, more girls (46% were underweight. On seeing the association, nutritional status of these adolescents within the normal limits were found to be significantly higher in those from nuclear families (P < 0.001, those with better educated parents (P < 0.000, and those from families of higher socioeconomic status (P < 0.000. Conclusion: Overall, among the participants, there were both macro- and micronutrients deficiencies. Therefore, there is a need to encourage people to adopt small family norms, and a need for the sensitization of both adolescents and their parents through health and nutrition education (HNE to improve the health and nutritional status of the adolescents.

    To explore the effect of maternal dietary intervention on infant essential fatty acid (FA) status, we conducted a prospective, single-blind, randomized nutrition intervention study. At the first trimester of pregnancy, 90 women from families with a history of allergy were randomized either to receive intensive dietary counseling to modify dietary intake according to current recommendations or as controls. Infants' cord and 1-mo isolated serum phospholipid FA were identified and quantified by GC. Detectable levels of eicosatrienoic acid [ETA, 20:3(n-9)] were taken as a biochemical marker for essential FA deficiency, and the DHA sufficiency index [22:6(n-3):22:5(n-6)] and the DHA deficiency index [22:5(n-6):22:4(n-6)] were taken as markers for DHA [22:6(n-3)] status. The concentration of ETA was lower in cord blood in the intervention (I) group [median 0.64 (IQR 0.40-0.78) mg/L; 2.09 (1.31-2.54) μmol/L] than in the control (C) group [0.92 (0.54-1.20) mg/L; 3.00 (1.76-3.92) μmol/L] (P = 0.048). The proportion of ETA in total FA in the I group [0.73% (0.48-0.85%)] was lower than in the C group [0.93% (0.78-1.22%)] (P = 0.003). A higher DHA sufficiency index and lower DHA deficiency index were detected in cord blood in the I group than in the C group, although the groups did not differ in the DHA concentration or proportion of the total FA. There were no differences among groups at 1 mo for any of the variables measured. Our findings suggest a better supply of essential FA, particularly important during the period of rapid development, in infants whose mothers received dietary counseling. The results thus highlight the importance of maternal diet for child health, calling for dietary counseling for pregnant women in primary health care.

    The dietary life of humans varies with the environment where they live and has been changing with time. It has become possible to examine such changes by using stable carbon and nitrogen isotope composition as a chemical tool. The present report outlines recent developments in the application of this tool and compares the dietary ecologies of various human groups from the viewpoint of isotope geochemistry. The history of the application of this tool to dietary analysis is summarized first, and features of the carbon and nitrogen isotope composition in animals and their relations with the food chain are outlined. The dietary ecology of the current people is then discussed in relation to the isotope composition in food, the isotope composition in hair of the current people, and determination of food habit of specific groups of people from such isotope compositions. For prediction of dietary composition, the report presents a flow chart for an algorism which is based on the Monte Carlo method. It also outlines processes for analyzing food habits of people in the prehistoric age, focusing on distribution of isotope composition in humans over the world. (N.K.)

    Achieving weight loss after bariatric surgery depends on the individual's ability to sustain lifestyle changes involving dietary modifications. Presurgical dietary assessment is critical to evaluate usual dietary habits and identify the need for intervention before surgery. The objective of this study was to identify usual dietary habits of black and white women seeking bariatric surgery and to examine potential differences between these ethnic groups. An additional aim was to describe participants' plans to change dietary behaviors after surgery. This study examined data from an observational study sponsored by a benefits management group in Louisiana. In this cross-sectional study, a presurgical dietary assessment interview questionnaire collected information on dietary habits. Participants (n = 200) were adult women being screened for bariatric surgery; 54% were white, and 46% were black. Descriptive statistics were calculated and differences between groups were tested using 2-way analysis of the variance. Participants reported consuming fast food 2.9 ± 2.6 times per week, fried foods 2.1 ± 1.8 times per week, and desserts 3.4 ± 3.2 times per week. Blacks reported more frequent consumption of fast food (P<.01), sugar-sweetened sodas (P<.05), and sugar-sweetened tea (P<.01) compared with whites. Plans for changing dietary behaviors after surgery were similar between ethnic groups. Findings indicated that frequent consumption of fast foods, fried foods, desserts, and sugar-sweetened beverages was common among women seeking bariatric surgery. Blacks tended to consume these foods and beverages more often than whites. Current dietary habits and future plans to change dietary behaviors should be addressed before surgery for success. Follow-up studies investigating the assessment instrument's ability to predict dietary adherence and weight loss after surgery are warranted. Copyright © 2018 American Society for Bariatric Surgery.

    A study was made to assess the impact of two late blight tolerant potato varieties Tigoni and Asante releases in 1998. The appraisal and impact assessment set out to collect information on the adoption of the two varieties; assess their economic impact; and forecast future prospects for these two varieties and identity constraints to their adoption and diffusion in three divisions of Molo, Timboroa and Laikipia. The methodology adopted was conducting field surveys between September and October 2001, and gathering secondary information from the Ministry of Agriculture, research Centres, seed companies, NGO's and farmers. Results indicated that high yield, early maturity, tolerant to late blight, good market for ware potatoes and good taste were the advantages of Tigoni and Asante, widely recognised in all survey sites. Disadvantages of Tigoni and Asante were poor storage, rapid greening of tubers (mainly for Tigoni), and limited availability of planting material. The two varieties had higher yield benefits, net benefit per hectare and higher rates of return compared to the local varieties. the rate of returns when the local cultivars were substituted by the new improved varieties ranged from 556 to 1070%. Data on diffusion of Tigoni and Asante showed that combined acreage of varieties Tigoni and Asante rose to 196.3, 137.5 and 1476 ha in Molo, Timboroa and Laikipia respectively. The future forecast for the two varieties is good if the limitation on seed availability is addressed

    The impact of climate change on crop yields has become widely measured; however, the linkages for winter wheat are less studied due to dramatic weather changes during the long growing season that are difficult to model. Recent research suggests significant reductions under warming. A potential adaptation strategy involves the development of heat resistant varieties by breeders, combined with alternative variety selection by producers. However, the impact of heat on specific wheat varieties remains relatively unstudied due to limited data and the complex genetic basis of heat tolerance. Here, we provide a novel econometric approach that combines field-trial data with a genetic cluster mapping to group wheat varieties and estimate a separate extreme heat impact (temperatures over 34 °C) across 24 clusters spanning 197 varieties. We find a wide range of heterogeneous heat resistance and a trade-off between average yield and resistance. Results suggest that recently released varieties are less heat resistant than older varieties, a pattern that also holds for on-farm varieties. Currently released - but not yet adopted - varieties do not offer improved resistance relative to varieties currently grown on farm. Our findings suggest that warming impacts could be significantly reduced through advances in wheat breeding and/or adoption decisions by producers. However, current adaptation-through-adoption potential is limited under a 1 °C warming scenario as increased heat resistance cannot be achieved without a reduction in average yields. © 2015 John Wiley & Sons Ltd.

    Traditionally, the Arctic diet has been derived entirely from locally harvested animal and plant species; however, in recent decades, imported foods purchased from grocery stores have become widely available. The present study aimed to examine Inuvialuit, traditional or nontraditional dietary patterns; nutrient density of the diet; dietary adequacy; and main food sources of energy and selected nutrient intakes. This cross-sectional study used a culturally appropriate quantitative food frequency questionnaire to assess diet. Traditional and nontraditional eaters were classified as those consuming more or less than 300 g of traditional food daily. Nutrient densities per 4184 kJ (1000 kcal) were determined. Dietary adequacy was determined by comparing participants' nutrient intakes with the Dietary Reference Intakes. The diet of nontraditional eaters contained, on average, a lower density of protein, niacin, vitamin B12 , iron, selenium, zinc, omega-3 fatty acids (P ≤ 0.0001), vitamin B6 , potassium, thiamin, pantothenic acid (P ≤ 0.001), riboflavin and magnesium (P ≤ 0.05). Inadequate nutrient intake was more common among nontraditional eaters for calcium, folate, vitamin C, zinc, thiamin, pantothenic acid, vitamin K, magnesium, potassium and sodium. Non-nutrient-dense foods (i.e. high fat and high sugar foods) contributed to energy intake in both groups, more so among nontraditional eaters (45% versus 33%). Traditional foods accounted for 3.3% and 20.7% of total energy intake among nontraditional and traditional eaters, respectively. Diet quality and dietary adequacy were better among Inuvialuit who consumed more traditional foods. The promotion of traditional foods should be incorporated in dietary interventions for this population. © 2014 The British Dietetic Association Ltd.

    To study consumer acceptance of unmilled brown and undermilled rice among urban south Indians. Overweight and normal weight adults living in slum and nonslum residences in Chennai participated (n = 82). Bapatla (BPT) and Uma (red pigmented) rice varieties were chosen. These rice varieties were dehusked (unmilled, 0% polish) and further milled to 2.3% and 4.4% polishing (undermilled). Thus, 9 rice samples in both raw and parboiled forms were provided for consumer tasting over a period of 3 days. A 7-point hedonic scale was used to rate consumer preferences. A validated questionnaire was used to collect demographic, anthropometric, medical history, physical activity, dietary intake data, and willingness of the consumers to switch over to brown rice. Consumers reported that the color, appearance, texture, taste, and overall quality of the 4.4% polished rice was strongly preferred in both varieties and forms. Ratings for 0% polished (brown rice) were substantially lower than those of 2.3% polished rice, which were intermediate in ratings between 0% and 4.4% polishing. However, most of the consumers (93%) expressed a willingness to substitute brown or 2.3% polished rice, if affordable, after the taste tests and education on nutritional and health benefits of whole grains. Though most consumers preferred polished white rice, education regarding health benefits may help this population switch to brown or undermilled rice. Cooking quality and appearance of the grains were perceived as the most important factors to consider when purchasing rice among Chennai urban adults.

    A new wheat variety named Hezu 8 was developed by in vitro mutation techniques combining the somatic tissue culture with the radiation-induced mutation. This is the first one in the world for breeding wheat variety in such a way, that the nuclear technology was successfully applied to biotechnology. Hezu 8 is featured by high yield potential, early maturity, disease resistance, tolerance to moisture as well as good grain quality. In vitro mutation technique has proved to be helpful in increment of the frequency of somaclonal variation, promotion of the variation stability, acceleration of breeding process, reduction of the population size for variant selection, and finally, improvement of the breeding efficiency. In vitro mutation technique can be also widely applied to other crops and will open up a brilliant prospect for crop improvement

  13. Dietary Fiber Analysis of Four Pulses Using AOAC 2011.25: Implications for Human Health

    Full Text Available Chickpeas, common beans, dry peas, and lentils are pulse crops that have been a cornerstone of the human diet since the inception of agriculture. However, the displacement of pulses from the diet by low fiber protein alternatives has resulted in a pervasive deficiency referred to as the dietary fiber gap. Using an analytical method American Association of Analytical Chemists (AOAC 2011.25 that conforms to the Codex Alimentarius Commission consensus definition for dietary fiber, the fiber content of these pulse crops was evaluated in seed types used for commercial production. These pulse crops have 2 to 3 times more fiber per 100 g edible portion than other dietary staples. Moreover, there is marked variation in fiber content among cultivars of the same crop. We conclude that pulse crop consumption should be emphasized in efforts to close the dietary fiber gap. The substantial differences in fiber content among currently available cultivars within a crop can be used to further improve gains in fiber intake without the need to change dietary habits. This provides a rationale for cultivar-based food labeling.

    In two experiments adult rats (aged at least 6 months at the start of the procedure) received a diet enriched with added choline for a period of 10 weeks; control subjects were maintained on a standard diet during this time. All rats then underwent the spontaneous object recognition (SOR) procedure in which they were exposed to a pair of objects and then tested, after a retention interval, to a display with one object changed. Exploration of the changed object indicates retention and use of information acquired during the exposure phase. All subjects showed retention with a 24-h interval (Experiments 1 and 2) and when retested after a further 24 h (Experiment 1). But when tested for the first time after a 48-h interval (Experiment 2), control subjects showed no evidence of retention, exploring both objects equally, whereas those given the dietary supplement continued to show a preference for the changed object. This supports the conclusion that dietary choline supplementation can enhance performance on a task regarded as a test of declarative memory, and will do so even when the supplementations is given in adulthood.

    Full Text Available The objective of this study was to understand the usage patterns of dietary supplements among professional athletes in Saudi Arabia. The survey consisted of sixteen questions divided into four categories: use of supplements, reason for consumption of supplements, personal beliefs about supplements, and behavior. The questionnaires were given to the three teams residing in Riyadh: Al Hilal, Al Nasr, and Al-Shabab. Out of the 105 athletes surveyed, we found that only 98 are currently taking dietary supplements and the mean age and standard deviation were 25.74±2.90. The survey results showed a high percentage of athletes (93.3%; n=98 using different dietary supplements throughout the season, 43.8% (n=43 reported using supplements for performance, and 32.6% (n=32 believed in health benefits as a reason for using dietary supplements. Our results showed that a total of 87 (88.7%, 81 (82.6%, and 51 (52.0% athletes are consuming sports drinks, vitamin C, and multivitamins, respectively. Meanwhile, those supplements ranking among the least used included omega 6 (18.6%, creatine (16.3%, and Ginkgo biloba (10.2%. A majority of athletes indicated that their use of supplements was for the purpose of improving their health and performance.

    Consumption of excess calories results in obesity and insulin resistance and has been intensively studied in mice and humans. The objective of this study was to determine the specific contribution of dietary fat rather than total caloric intake to the development of obesity-associated insulin resistance. We used an intragastric feeding method to overfeed excess calories from a low-fat diet (and an isocalorically matched high-fat diet) through a surgically implanted gastric feeding tube to generate obesity in wild-type mice followed by hyperinsulinemic-euglycemic clamp studies to assess the development of insulin resistance. We show that overfeeding a low-fat diet results in levels of obesity similar to high-fat diet feeding in mice. However, despite a similar body weight, obese high-fat diet-fed mice are more insulin resistant than mice fed an isocaloric low-fat diet. Therefore, increased proportion of calories from dietary fat further potentiates insulin resistance in the obese state. Furthermore, crossover diet studies revealed that reduction in dietary fat composition improves glucose tolerance in obesity. In the context of the current obesity and diabetes epidemic, it is particularly important to fully understand the role of dietary macronutrients in the potentiation and amelioration of disease.

    Dietary patterns are often considered as one of the main causes of non-communicable diseases worldwide. It is of utmost importance to study dietary habits in developing countries since this work is scarce. To summarize the most recent research conducted in this field in African countries, namely the most used methodologies and tools. A systematic review was conducted on MEDLINE®/PubMed, aiming to identify scientific publications focused on studies of dietary intake of different African populations, in a ten-year period. Papers not written in English/Portuguese/Spanish, studies developed among African people but not developed in African countries, studies aiming to assess a particular nutrient/specific food/food toxin and studies that assessed dietary intake among children were excluded. Out of 99 included studies, the 24-hour recall and the food-frequency questionnaire were the most used dietary intake assessment tools, used to assess diet at an individual level. It was also observed that often country-unspecific food composition databases are used, and the methodologies employed are poorly validated and standardized. There is an emergent need to improve the existing food databases by updating food data and to develop suitable country-specific databases for those that do not have their own food composition table.

    We investigated the effect of the replacement of dietary fish oil with vegetable oils on the growth and flesh quality of large yellow croaker ( Larmichthys crocea). The basal diet (FO) was formulated to contain 66.5% fish meal and 6.4% menhaden fish oil; whereas the other 3 experimental diets were formulated by replacing the fish oil with 50% soybean oil (SO50), 100% soybean oil (SO100) and 100% palm oil (PO100), respectively. The 4 diets were randomly assigned to 4 floating sea cages (3.0 m × 3.0 m × 3.0 m), and each was stocked with 250 fish individuals with an initial average weight of 245.29 g ± 7.45 g. The fish were fed to apparent satiation twice a day at 5:00 and 17:00, respectively, for 12 weeks. Experimental analysis showed that the specific growth rate of fish fed SO50 or PO100 were significantly higher than that of fish fed FO or SO100 ( P0.05). Compared to FO diet, SO50, SO100 and PO100 diets led to substantial decreases in the liquid loss and water loss from fresh fillets (1 d, 4°C) ( Preplacement of fish oil with vegetable oils. These findings indicated that the growth performance and selected flesh quality properties (liquid holding capacity and TBARS value) of large yellow croaker were substantially improved by replacing dietary fish oil with vegetable oils.

    Diet, along with lifestyle factors, is an important determinant of the health status of an individual and of a community. Dietary assessment at the population level provides us with key information on the frequency and distribution of possible inadequate diets and/or nutritional status. It is also useful as input into the elaboration of food and nutrition policies aiming to improve dietary habits and the health status of a community. This article reviews the characteristics, advantages and limitations of the 24-hour dietary recall method (24hDR), which is one of the most widely used tools in nutrition epidemiology to identify food, energy and nutrient intake in national nutrition surveys, cross-sectional studies, clinical trials and cohort studies as well as in the evaluation of individual dietary intake and Total Diet assessment. To reduce the key factors associated with bias, the importance of previously trained interviewers is highlighted, as well as the role of support materials and the contribution of novel technologies.

    To examine within-person variation in dietary self-monitoring during a 6-month technology-supported weight loss trial as a function of time-varying factors including time in the study, day of the week, and month of the year. Smartphone self-monitoring data were examined from 31 obese adults (aged 18-60 years) who participated in a 6-month technology-supported weight loss program. Multilevel regression modeling was used to examine within-person variation in dietary self-monitoring. Participants recorded less as time in the study progressed. Fewer foods were reported on the weekends compared with weekdays. More foods were self-monitored in January compared with October; however, a seasonal effect was not observed. The amount of time in a study and day of the week were associated with dietary self-monitoring but not season. Future studies should examine factors that influence variations in self-monitoring and identify methods to improve technology-supported dietary self-monitoring adherence.
