    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.

    Full Text Available Parkinson’s disease (PD is the second most common neurodegenerative disorder. The majority of cases do not arise from purely genetic factors, implicating an important role of environmental factors in disease pathogenesis. Well-established environmental toxins important in PD include pesticides, herbicides, and heavy metals. However, many toxicants linked to PD and used in animal models are rarely encountered. In this context, other factors such as dietary components may represent daily exposures and have gained attention as disease modifiers. Several in vitro, in vivo, and human epidemiological studies have found a variety of dietary factors that modify PD risk. Here, we critically review findings on association between dietary factors, including vitamins, flavonoids, calorie intake, caffeine, alcohol, and metals consumed via food and fatty acids and PD. We have also discussed key data on heterocyclic amines that are produced in high-temperature cooked meat, which is a new emerging field in the assessment of dietary factors in neurological diseases. While more research is clearly needed, significant evidence exists that specific dietary factors can modify PD risk.

  4. Cancer preventive role of selected dietary factors

    Full Text Available Dietary behavior seems to be an important modifiable determinant for the risk of cancer. The evidences from several epidemiological studies suggest that higher intakes of fruits and vegetables have been associated with lower risk of cancer. Dietary phenolic and polyphenolic substances, terpenoids, dietary fibers, fish oils, some micronutrients present in foods of both plant and animal origin, and a reduction of caloric intake appear to inhibit the process of cancer development. Many dietary factors possess antioxidant and anti-inflammatory properties and cause induction of phase II enzymes like glutathione-S-transferases. It has been suggested that cruciferous vegetables play an important role in cancer prevention, and their chemopreventive effects are due to high glucosinolate content which under enzymatic hydrolysis produces bioactive compound isothiocyanates. Further, isothiocyanates of a wide variety of cruciferous vegetables are powerful inhibitors of carcinogenesis in experimental animal models. Several flavonoids present in fruits, tea, soya beans, etc. may be useful as cancer preventive agents. Similarly, ellagic acid, perillyl alcohol and resveratrol found in various fruits may have chemoprotective effect. Moreover, different vanilloids such as curcumin and gingerol have been shown to possess antioxidative properties. Nevertheless, in spite of several studies, still the effects of various ingredients are not clearly distinguished. In human, little convincing evidence has been established for the proposed protective effects of dietary constituents. It is an important future research goal to provide necessary evidences to support the chemopreventive role of different dietary factors, and also to clarify misunderstandings in this perplexing area.

  5. Colorectal cancer: lifestyle and dietary factors

    M. P. Corrêa Lima

    Full Text Available Introduction: Colorectal cancer is the most common tumor in the developed countries, and the number of new cases annualy is aproximately equal for men and women. Several environmental factors can interact in all steps of carcinogenesis. Lately the balance between genetic predisposition and these factors, including nutritional components and lifestyle behaviors, determines individual susceptibility to develop colorectal cancer. The aim of this study is to revise the references about lifestyle include diet, physical exercise, tobacco smoking and use of alcohol, and the risk of colorectal cancer in databases published during 1994-2004. Dietary factors: According to the reports high intake of red meat, and particularly of processed meat and positive energetic balance (high intake of total fat and carbohydrate was associated with a moderate but significant increase in colorectal cancer risk. Convincing preventive factors include increase consumption of a wide variety of fruit and vegetable, particularly, dark-green leafy, cruciferous, a deep-yellow on tones, and fibre. Lifestyle: Physical activity as a means for the primary prevention of colorectal cancer. There is a probable synergic effect among physical inactivity, high energy intake and obesity and incidence of colorectal cancer. A growing body of evidence supports that avoidance overweight and the use of tobacco and alcohol is recommended to prevent colorectal cancer. Conclusion: Current data suggest that lifestyle modification including proper diet such as the ones rich in vegetable and poor in red meat and fat, regular physical activity and maintaining an appropriate body weight and avoiding the use of tobacco and alcohol may lead to reduce colorectal cancer risk.

    Full Text Available The present cross-sectional study was designed to assess the frequency of 36 possible triggering factors precipitating a migraine crisis (hormonal, environmental, and dietary in adult outpatients suffering from migraine attacks. A group of 123 migraine sufferers, aged 43.2 ± 13.9 (mean ± SD years, including 114 (92.7% women, 68.3% having migraine without aura, 68.3% reporting pain severe enough to require drug prophylaxis, and 29.3% presenting with hypertension, were evaluated. The most common triggers were stress and fasting, and environmental and hormonal factors were frequently found to precipitate a crisis. More than 90% of the patients reported susceptibility to 5 or more factors, and only 2.4% did not complain about any dietary factor. The large number of triggers detected in the present study emphasises the importance of awareness and avoidance of these factors in the management of patients with migraine.

    Some dietary factors are proposed to affect thyroid carcinogenesis, but previous studies have reported inconsistent findings. Therefore, we performed a meta-analysis, including 18 eligible studies, to clarify the role of dietary factors in the risk of thyroid cancer. The relative risks (RRs) with 95% confidence intervals (95% CIs) were estimated to assess the association and heterogeneity tests and subgroup and sensitivity analyses, and bias assessments were performed. When the results from all studies were combined, dietary iodine, fish, and cruciferous vegetable intake were not associated with thyroid cancer. However, when the data were divided by geographic location based on iodine availability, a slight increase in the risk of thyroid cancer was observed among those consuming a high total amount of fish in iodine nondeficient areas (RR: 1.18; 95% CI: 1.03-1.35; P for heterogeneity = 0.282). When excluding the studies examining a single food item and hospital-based controls, a high intake of cruciferous vegetables was associated with an increased risk of thyroid cancer in iodine-deficient areas (RR: 1.43; 95% CI: 1.18-1.74; P for heterogeneity = 0.426). This meta-analysis implies that the role of dietary factors, such as fish and cruciferous vegetables, in thyroid cancer risk can differ based on iodine availability.

    Full Text Available Abstract Background The deterioration of the health status of the Romanian population during the economic transition from a centrally planned to a free market economy has been linked to lifestyles factors (e.g. diet regarded as a main determinants of the disparity in life expectancy between Eastern and Western Europe. Reforms in the health care system in this transition economy aim to focus on preventive action. The purpose of this study was to identify the factors that impact on the individual decision to engage in Dietary Health Preventive Behaviour (DHPB and investigate their influence in the context of an adapted health cognition model. Methods A population-based study recruited 485 adult respondents using random route sampling and face-to-face administered questionnaires. Results and discussion Respondents' health motivation, beliefs that diet can prevent disease, knowledge about nutrition, level of education attainment and age have a positive influence on DHPB. Perceived barriers to healthy eating have a negative impact on alcohol moderation. The information acquisition behaviour (frequency of reading food labels is negatively predicted by age and positively predicted by health motivation, education, self-reported knowledge about nutrition and household financial status. A significant segment of respondents believe they are not susceptible to the elicited diseases. Health promotion strategies should aim to change the judgments of health risk. Conclusion The adaptation of the Health Belief Model and the Theory of Health Preventive Behaviour represents a valid framework of predicting DHPB. The negative sign of perceived threat of disease on DHPB may suggest that, under an income constraint, consumers tend to trade off long-term health benefits for short-term benefits. This cautions against the use of negative messages in public health campaigns. Raising the awareness of diet-disease relationships, knowledge about nutrition (particularly

    2010-02-01

    Full Text Available The aim of this study was to clarify the factors influencing the dietary behavior of patients with diabetic nephropathy. One hundred twenty-two patients with type 2 diabetes were recruited from the outpatients of Okayama University Hospital in Okayama, Japan. We performed a cross-sectional study using a questionnaire including 206 items among 18 categories as follows:background factors, coping behavior (coping scale, degree of uncertainty in illness (uncertainty scale, and dietary behavior. The data were analyzed by correlation analysis, t-test, one-way analysis of variance, Pearson correlation analysis, and multiple regression analysis. We found that those patients with microalbuminuria alone tended to recognize more mild about their kidney status than those with macroalbuminuria and chronic renal failure. We also found that common factors influencing the dietary behavior of diabetic patients with and without nephropathy are as follows:1. coping with the problem (beta0.342, p0.01;2. anxiety about prognosis (beta0.344, p0.01;3. sex (beta0.234, p0.05;4. uncertainty regarding treatment (beta0.377, p0.01;5. negative coping (beta0.354, p0.01;and 6. employment status (beta0.367, p0.01. Coping and uncertainty in illness had a significant relation to positive support and lack of support. To maintain appropriate dietary behavior in diabetic patients, medical staff need to determine what the social supports are important for the patient, and also to ensure good communication among healthcare personnel as well as positive support for patients and families.

    2015-12-01

    The goal of the present study was to examine dietary adherence and acceptability among participants from the New DIETs study who were randomized to one of four plant-based diets (vegan, vegetarian, pesco-vegetarian, semi-vegetarian) or an omnivore diet. Primary outcomes at two- and six months included dietary adherence (24-hour dietary recalls), weight loss and changes in animal product intake (mg cholesterol) by adherence status, Three-Factor Eating Questionnaire (TFEQ), Power of Food Scale (PFS), dietary acceptability (Food Acceptability Questionnaire), and impact of diet preference on adherence. No differences were found in dietary adherence or changes in FAQ, TFEQ, or PFS among the groups. At six months, non-adherent vegan and vegetarian participants (n=16) had a significantly greater decrease in cholesterol intake (-190.2 ± 199.2 mg) than non-adherent pesco-vegetarian/semi-vegetarian (n=15, -2.3 ± 200.3 mg, P=0.02) or omnivore participants (n=7, 17.0 ± 36.0, P=0.04). Non-adherent vegan/vegetarian participants lost significantly more weight at six months (-6.0 ± 6.7%) than non-adherent omnivore participants (-0.4 ± 0.6%, P=0.04). Dietary preference had no impact on adherence at six months. Due to equal rates of adherence and acceptability among the diet groups, instructing participants to follow vegan or vegetarian diets may have a greater impact on weight loss and animal product intake than providing instruction in more moderate approaches even among non-adherent participants.

    Full Text Available Nutritional factors are known to be important in the development of different metabolic diseases. The history of nodular or diffuse goiter is closely related to risk of thyroid carcinoma. On account of the function of the thyroid gland, many studies focus on iodine intake.The aim of the study was to assess whether dietary patterns could be risk factors of differentiated thyroid carcinoma.Material/Methods:The case-control study was based on a questionnaire, which included information about dietary patterns and was carried out on 284 patients comprising 30 males (mean age 58.4±13.7 years, and 254 females (mean age 52.1±13.8 years, as well as 345 randomly selected controls: 58 males (mean age 60.2±12 years and 287 females (mean age 53.4±14.3 years randomly selected from the Population Register and adjusted by age and gender to the group of TC. The main groups of nutritional products, i.e. starchy foods, meat, dairy products, vegetables, fruits, and beverages, were analyzed.Results:Consumption of vegetables, fruits, saltwater fish and cottage cheese was significantly lower in patients with differentiated thyroid carcinoma than in controls, quite the contrary to starchy foods, especially white bread.Conclusions:Dietary patterns appear to modify the risk of thyroid carcinoma. A diet rich in vegetables and fruit, as well as saltwater fish (a source of iodine and low-fat meat, could be an important protective factor.

    There is increasing evidence that dietary factors in plant-based diets are important in the prevention of chronic disease. This study examined protective (eg, antioxidant vitamins, carotenoids, and fiber) and pathogenic (eg, saturated fatty acids and cholesterol) dietary factors in a very-low-fat vegan diet. Ninety-three early-stage prostate cancer patients participated in a randomized controlled trial and were assigned to a very-low-fat (10% fat) vegan diet supplemented with soy protein and lifestyle changes or to usual care. Three-day food records were collected at baseline (n=42 intervention, n=43 control) and after 1 year (n=37 in each group). Analyses of changes in dietary intake of macronutrients, vitamins, minerals, carotenoids, and isoflavones from baseline to 1 year showed significantly increased intake of most protective dietary factors (eg, fiber increased from a mean of 31 to 59 g/day, lycopene increased from 8,693 to 34,464 mug/day) and significantly decreased intake of most pathogenic dietary factors (eg, saturated fatty acids decreased from 20 to 5 g/day, cholesterol decreased from 200 to 10 mg/day) in the intervention group compared to controls. These results suggest that a very-low-fat vegan diet can be useful in increasing intake of protective nutrients and phytochemicals and minimizing intake of dietary factors implicated in several chronic diseases.

    West, Christina E; D'Vaz, Nina; Prescott, Susan L

    2011-08-01

    Emerging evidence suggests that exposures during pregnancy and the early postnatal period can modify gene expression and disease propensity. Diet is a major environmental exposure, and dietary factors, including polyunsaturated fatty acids, probiotics, oligosaccharides, antioxidants, folate, and other vitamins, have effects on immune function. Some also have been implicated in reduced risk of allergy in observational studies. Intervention trials with polyunsaturated fatty acids, probiotics, and oligosaccharides suggest preliminary but as-of-yet-unconfirmed benefits. Food allergen avoidance during pregnancy, lactation, or infancy has provided no consistent evidence in allergy prevention and is no longer recommended. Rather, there is now a focus on food allergens in tolerance induction. Specific nutrients can induce changes in gene expression during early development and have been implicated in potentially heritable "epigenetic" changes in disease predisposition. Collectively, these observations emphasize that early exposures may modify tolerance development and that further research on these exposures should remain a priority.

    To estimate associations between dietary factors and pancreatitis in dogs. Design-Retrospective case-control study. 198 dogs with a clinical diagnosis of pancreatitis and 187 control dogs with a diagnosis of renal failure without clinical evidence of pancreatitis. Information on signalment, weight, body condition, dietary intake, medical history, diagnostic tests performed, concurrent diseases, treatments, duration of hospitalization, and discharge status was extracted from medical records. Information on dietary intake, signalment, weight, and medical, surgical, and environmental history was collected through a telephone questionnaire. Logistic regression was used to estimate odds ratios (OR) and 95% confidence intervals. On the basis of information extracted from the medical record, ingesting unusual food items (OR, 4.3) increased the odds of pancreatitis. On the basis of information gathered through the telephone questionnaire, ingesting unusual food items (OR, 6.1), ingesting table scraps the week before diagnosis (OR, 2.2) or throughout life (OR, 2.2), and getting into the trash (OR, 13.2) increased the odds of pancreatitis. Multivariable modeling indicated that reporting exposure to > or = 1 dietary factor during the telephone questionnaire (OR, 2.6), being overweight (OR, 1.3) or neutered (OR, 3.6), previous surgery other than neutering (OR, 21.1), and the interaction between neuter status and previous surgery other than neutering (OR, 0.1) were associated with the odds of pancreatitis. Results suggested that dietary factors, being neutered, and previous surgery other than neutering increased the odds of pancreatitis in dogs.

    Hypertension is the most common psychosomatic disorder affecting 972 million people worldwide being more prevalent in old age. The present survey of hypertensive patients fulfilling the standard diagnostic criteria of WHO/ISH (2004) is carried out in geriatric age group from the Saurashtra region of Gujarat in India to observe the dietary pattern and provocative factors. Total 120 patients of 50 to 80 years of age having systolic blood pressure >140 mm Hg and ≤180 mm Hg and diastolic blood pressure >90 mm Hg and ≤110 mm Hg irrespective of gender and religion were selected for the present study. They were interviewed for list of provocative factors enlisted in Ayurveda. As observed, the study supported the facts described in Ayurveda that dietary etiological factors, such as excess intake of Lavana (salty), Amla (sour), Katu (pungent), Tikshna, Ushna (hot), Vidahi (producing burning sensation), Viruddha (incompatible), Snigdha (unctuous), Abhishyandi (leading to obstruction), Madhura (sweet), Guru (heavy to digest) dietary articles, Ajirnashana (taking diet before complete digestion of previous meal), Adhyashana (repeated eating at short intervals), will vitiate Rakta dhatu as well as Pitta dosha in the body leading to disorders like hypertension. Hypertension in old age is found to be a disease of Vata-Pitta dominant vitiation with the involvement of Rasa, Rakta, Meda as main Dushya (vitiated factors) and dietary factors can contribute to worsening of the disease. The etiological factors having role in the pathogenesis can also be applied for preventive guidelines for the management of hypertension.

    The purpose of this study was to examine the cross-sectional associations between dietary glycemic index (GI) and glycemic load (GL) and cardiovascular disease (CVD) risk factors in Chinese children. A total of 234 Chinese schoolchildren aged 8-11 years in Guangdong participated in the study. Dietary intake was assessed via a 3-day dietary record. Seven established cardiovascular indicators were analyzed in this study: fasting plasma glucose (FPG), fasting triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), systolic blood pressure, and diastolic blood pressure. Higher dietary GI was significantly associated with higher TG levels (P = 0.037) and lower HDL-C levels (P = 0.005) after adjusting for age, sex, nutritional intake, physical activity, and body mass index z score. LDL-C was found to differ across tertiles of dietary GL. The middle tertile tended to show the highest level of LDL-C. TC, FPG, and blood pressure were independent of both dietary GI and GL. Our findings suggest that higher dietary GI is differentially associated with some CVD risk factors, including lower HDL-C and higher TG, in school-aged children from south China.

    Full Text Available Diet is an important factor related to the development of numerous diseases. In developing countries like Ecuador, this aspect is not considered as priority however, the study of the incidence of certain diet-related diseases could help to assess consumption habits of a country from a Public Health perspective and support national nutrition policies and programs. The objective the present study is to investigate the mortality rate of certain diet-related diseases in Ecuador and its possible relationship with Ecuadorian consumption habits. For that, mortality rates (2001-2008 associated with five different disease groups related to dietary factors (cancer of colon, cerebrovascular diseases, cardiovascular diseases, diabetes mellitus and liver diseases were collected, analyzed and compared to consumption patterns in Ecuador. According to results, Ecuador has a low level of cancer of colon in comparison with developed countries (e.g. Spain. The group with the highest number of deaths corresponded to cardiovascular diseases followed by cerebrovas-cular diseases. The mortality study per province revealed that Amazonian provinces showed few deaths in relation to other provinces in Ecuador. This could be due to different factors including fails in the disease surveillance information systems, environmental factors and consumption patterns. In this sense, further investigation on native products consumption such as "chontaduro" might help to find valuable foods contributing to healthier Ecuadorian diet. These results, though preliminary, evidence that a major effort should be made by national and international organisations to collect data on consumption patterns and nutritional aspects of the Ecuadorian population in order to better support the development of effective food security and nutrition policies.

    2014-01-01

    A literature search was done using PubMed. The age at natural menopause (ANM) depends on various factors like genetic, environmental, socioeconomic, reproductive, dietary, and lifestyle of which some like nulliparity, vegetarian diet, smoking, high fat intake, cholesterol, and caffeine accelerates; while others like parity, prior use of oral contraceptive pills, and Japanese ethnicity delays the ANM. ANM is an important risk factor for long-term morbidity and mortality; and hence, the need to identify the modifiable risk factors like diet and lifestyle changes. Delayed menopause is associated with increased risk of endometrial and breast cancer, while early ANM enhances the risk for cardiovascular diseases and osteoporosis. The correlation between diet and ANM has not been extensively studied; however, whatever studies have been done till now point towards role of high intake of total calories, fruits, and proteins in delaying the ANM, while high polyunsaturated fat intake accelerates it. The role of dietary soy, total fat, saturated fat, red meat, and dietary fiber in determining the ANM has been controversial and needs further studies to substantiate it. The lifestyle factors like current smoking and vigorous exercise have been significantly associated with early menopause, while moderate alcohol consumption delays the ANM. Large prospective studies are needed to study the association of ANM and other modifiable factors like passive smoking fish consumption, soy, and various types of tea. The knowledge of modifiable determinants of ANM can help in setting up menopausal clinics and initiating health programs specially in developing countries.

    Full Text Available Background and Aim. Helicobacter pylori (HP and diet are both risk factors for gastric cancer. The aim of this study was to evaluate the Helicobacter pylori infection and dietary habits common in Khuzestan province. Methods. This cross-sectional study was conducted in 2011–2013 on 374 patients. Participants were interviewed using a food frequency questionnaire and tissue sample of the antrum was sent for pathology lab. The histopathological major variables were graded on a scale of 3 (mild, moderate, and severe and data analyzed using nonparametric tests. Results. In this study, of 160 patients (43% that were determined, 8.1 percent had severe contamination. Among dietary patterns, relationship between energy intake and carbohydrate with H. pylori was significant. A direct association was found between mean daily intakes of sausage (P=0.001 and burgers (P<0.05 with HP infection. Low intake of fresh vegetables and fruits was the most significant risk factors (P<0.05. Conclusion. There is a possibility that some dietary factors such as consumption of fast foods and low intake of fresh vegetables may increase the chance of HP and severity of this infection.

    Aggression during mixing of pregnant sows impacts sow welfare and productivity. The aim of this study was to increase satiety and reduce aggression by including dietary fiber and fermentable carbohydrates. Sows were housed in individual stalls 7 to 14 d after breeding (moving day was considered d 0 of treatment) and were fed (at 0700 h) with a CONTROL (corn-soybean meal based with no additional fiber sources), RSTARCH (10.8% resistant starch), BEETPULP (27.2% sugar beet pulp), SOYHULLS (19.1% soybean hulls), or INCSOY (14.05% soybean hulls) for 21 d (5 sows/diet × 5 diets × 8 replications = 200 sows). The CONTROL diet was targeted to contain 185 g(d∙sow) NDF and the other diets were targeted to contain 350 g(d∙sow) NDF. The INCSOY diet was fed at 2.2 kg/(d∙sow) and the other diets were fed at 2 kg(d∙sow). On d 22, sows were mixed in groups of 5 (at 1200 h). Behaviors in stalls (on d 1, 7, 14, and 21) and after mixing (d 22 and 23), heart rate (on d 1, 7, 14, and 21), blood metabolites (on d 2, 8, 15, 22, and 25), and the effects of diets on production were collected and analyzed. Sows stood more ( 0.05). Average birth weight was lowest in the INCSOY diet ( = 0.02). This study demonstrates that RSTARCH and SOYHULLS can improve the welfare of sows by reducing aggression and increasing satiety in limit-fed pregnant sows without affecting production.

    Although the French eating model may differ from those of other countries, no studies to date have investigated dietary patterns in a wide age range of adults and at the national level. We aimed to identify dietary patterns (DP) of French adults and assess their associations with demographic, socio-economic and behavioural factors. The present study included 2624 adults (1087 men, 1537 women) aged 18-79 years from the cross-sectional national French INCA2 dietary survey. Dietary data were collected using a 7-day estimated food record. Clusters of DP were derived using principal component analysis and clustering, conjointly. Age-adjusted logistic regression analyses were used to investigate the association between DP and correlates. Five DP were identified, namely 'traditional', 'prudent', 'diversified', 'processed' and 'sandwiches'. Men were more likely to follow a traditional diet and women the 'prudent' pattern. Members of the 'processed' and 'sandwiches' patterns were younger compared to non-members. Healthier dietary patterns were overall positively associated with a higher socio-economic position, healthier behaviours (in terms of sedentary behaviours and smoking status) and lower body mass index. Under-reporting of energy intake, restrictive diet to lose weight and dietary supplement consumption were also related to specific DP, although differentially in men and women. Associations with contextual factors (i.e. household composition, agglomeration size and region) were also observed. The identification of adults' dietary patterns and associated behaviours (all modifiable) is important for the conceptualisation of multi-behavioural programs. The additional information on social and environmental correlates is also essential for targeting the most vulnerable population groups in the context of such public health interventions. © 2015 The British Dietetic Association Ltd.

    Objective To investigate the associations between socio-demographic status, lifestyle factors, dietary patterns and urinary total phthalate concentration in a cohort of South Australian men. Method We randomly selected 1527 males aged 39 to 84 from wave two of the Men Androgen Inflammation Lifestyle Environment and Stress (MAILES) study. Total phthalate concentration was examined in fasting morning urine samples. Socio-demographic and lifestyle factors were assessed by questionnaire. Food intake was assessed by food frequency questionnaire (FFQ). Dietary patterns were constructed using factor analysis. Results Total phthalates were detected in 99.6% of the urine samples. The overall geometric mean (95% CI) of total phthalate concentration was 112.4 (107.5–117.5) ng/mL. The least square geometric means (LSGMs) of total phthalate concentration were significantly higher among people who were obese (127.8 ng/mL), consuming less than two serves fruit per day (125.7 ng/mL) and drinking more than one can (375mL) of carbonated soft drink per day (131.9 ng/mL). Two dietary patterns were identified: a prudent dietary pattern and a western dietary pattern. Both the western dietary pattern (p = 0.002) and multiple lifestyle risk factors including smoking, obesity, insufficient physical activity and the highest quartile of the western dietary pattern (psocio-demographic status. Conclusion Phthalate exposure is ubiquitous and positively associated with lifestyle risk factors in urban dwelling Australian men. PMID:25875472

    Pereira Panza, Vilma Simões; Diefenthaeler, Fernando; da Silva, Edson Luiz

    2015-09-01

    The purpose of this review was to critically discuss studies that investigated the effects of supplementation with dietary antioxidant phytochemicals on recovery from eccentric exercise-induced muscle damage. The performance of physical activities that involve unaccustomed eccentric muscle actions-such as lowering a weight or downhill walking-can result in muscle damage, oxidative stress, and inflammation. These events may be accompanied by muscle weakness and delayed-onset muscle soreness. According to the current evidences, supplementation with dietary antioxidant phytochemicals appears to have the potential to attenuate symptoms associated with eccentric exercise-induced muscle damage. However, there are inconsistencies regarding the relationship between muscle damage and blood markers of oxidative stress and inflammation. Furthermore, the effectiveness of strategies appear to depend on a number of aspects inherent to phytochemical compounds as well as its food matrix. Methodological issues also may interfere with the proper interpretation of supplementation effects. Thus, the study may contribute to updating professionals involved in sport nutrition as well as highlighting the interest of scientists in new perspectives that can widen dietary strategies applied to training.

    The incidence of gastroesophageal reflux disease (GERD) is increasing in Korea. The aim of this study was to evaluate the relationship between GERD symptoms and dietary factors in Korea. From January 2007 to April 2008, 162 subjects were enrolled (81 in GERD group and 81 in control group). They were asked to complete the questionnaires about GERD symptoms and dietary habits. The symptom severity score was recorded by visual analogue scale. Subjects with overweight or obesity had an increased risk for GERD (OR, 2.52; 95% CI, 1.18-5.39). Irregular dietary intake was one of the risk factors for GERD (OR, 2.33; 95% CI, 1.11-4.89). Acid regurgitation was the most suffering (2.85 ± 2.95 by visual analogue scale) and frequent reflux-related symptom (57.5%) in GERD. Noodles (OR, 1.22; 95% CI, 1.12-1.34), spicy foods (OR, 1.09; 95% CI, 1.02-1.16), fatty meals (OR, 1.20; 95% CI, 1.09-1.33), sweets (OR, 1.42; 95% CI, 1.00-2.02), alcohol (OR, 1.16; 95% CI, 1.03-1.31), breads (OR, 1.17; 95% CI, 1.01-1.34), carbonated drinks (OR, 1.69; 95% CI, 1.04-2.74) and caffeinated drinks (OR,1.41; 95% CI, 1.15-1.73) were associated with symptom aggravation in GERD. Among the investigated noodles, ramen (instant noodle) caused reflux-related symptoms most frequently (52.4%). We found that noodles, spicy foods, fatty meals, sweets, alcohol, breads, carbonated drinks and caffeinated drinks were associated with reflux-related symptoms.

    This article examined the association between dietary patterns and cardiovascular risk factors in Chinese older adults. For this study, older adults with one or more cardiovascular risk factors or a history of cardiovascular disease were randomly selected using health check medical records from the Changshu and Beijing Fangshan Centers for Disease Control and Prevention. Exploratory factor analysis and cluster analysis was used to extract dietary pattern factors. Log binomial regression analysis was used to analyse the association between dietary patterns and chronic disease related risk factors. Four factors were found through factor analysis. A high level of internal consistency was obtained, with a high Cronbach's alpha coefficient of 0.83. Cluster analysis identified three dietary patterns: healthy diet, Western diet, and balanced diet. Findings in this sample of Chinese adults correspond to those reported in previous studies, indicating that a Western diet is significantly related to likelihood of having obesity, hypertension and the metabolic syndrome. The identification of distinct dietary patterns among Chinese older adults and the nutritional status of people with chronic diseases suggest that the three dietary patterns have a reasonable level of discriminant validity. This study provides evidence that a FFQ is a valid and reliable tool to assess the dietary patterns of individuals with chronic diseases in small- to medium-size urban and rural settings in China. It also validates the significant association between dietary pattern and cardiovascular disease risk factors, including body mass index, blood pressure, triglycerides, and metabolic conditions. Clinical diagnosis of chronic disease further confirmed this relationship in Chinese older adults.

    2013-01-01

    Allergic reactions to food can significantly reduce the quality of life and even result in life-threatening complications. In addition, the prevalence of food allergy has increased in the last decades in industrialized countries and the mechanisms underlying (increased) sensitization are still not fully understood. It is believed that the development and maintenance of oral tolerance to food antigens is a process actively mediated by the immune system and that this reaction is essential to inhibit sensitization. Ongoing research indicates that different dietary factors also may contribute to immune homeostasis and oral tolerance to food and that food processing modulates allergenicity. One of the major questions in food allergy research is therefore which impact nutrition and food processing may have on allergenicity of food and perhaps on sensitization. We summarize in this review the different dietary factors that are believed to contribute to induction of oral tolerance and discuss the underlying mechanisms. In addition, the functional consequences of allergen modification will be emphasized in the second part as severity of allergic reactions and perhaps sensitization to food is influenced by structural modifications of food allergens.

    In September 2013, the Hawaii Department of Health (HDOH) was notified of seven adults who developed acute hepatitis after taking OxyELITE Pro™, a weight loss and sports dietary supplement. CDC assisted HDOH with their investigation, then conducted case-finding outside of Hawaii with FDA and the Department of Defense (DoD). We defined cases as acute hepatitis of unknown etiology that occurred from April 1, 2013, through December 5, 2013, following exposure to a weight loss or muscle-building dietary supplement, such as OxyELITE Pro™. We conducted case-finding through multiple sources, including data from poison centers (National Poison Data System [NPDS]) and FDA MedWatch. We identified 40 case-patients in 23 states and two military bases with acute hepatitis of unknown etiology and exposure to a weight loss or muscle building dietary supplement. Of 35 case-patients who reported their race, 15 (42.9%) reported white and 9 (25.7%) reported Asian. Commonly reported symptoms included jaundice, fatigue, and dark urine. Twenty-five (62.5%) case-patients reported taking OxyELITE Pro™. Of these 25 patients, 17 of 22 (77.3%) with available data were hospitalized and 1 received a liver transplant. NPDS and FDA MedWatch each captured seven (17.5%) case-patients. Improving the ability to search surveillance systems like NPDS and FDA MedWatch for individual and grouped dietary supplements, as well as coordinating case-finding with DoD, may benefit ongoing surveillance efforts and future outbreak responses involving adverse health effects from dietary supplements. This investigation highlights opportunities and challenges in using multiple sources to identify cases of suspected supplement associated adverse events. Published 2016.

    China's nutrition transition is characterized by dramatic increases in overweight and cardiometabolic (CM) risk. The burden of obesity, CM risk factors and dietary intake among Chinese children were explored. Children 7-12 y old from the 2009 China Health and Nutrition Survey with available dietary intake data, anthropometry, blood pressure, and fasting blood samples were included (n=663). CM risk prevalence was calculated; logistic regression was used to investigate the association of nutrient intakes with CM risk, adjusting for age, gender, physical activity, area of residence and income. 14% of Chinese school-aged children and ~20% of those from urban areas and higher income households had overweight/obesity (pchildren and >=30% of those from urban areas and higher income households had impaired glucose/ HbA1c (pchildren had pre-dyslipidemia (i.e. at least one lipid measurement above borderline levels) and 21% of children had dyslipidemia. Approximately 30% of all children had energy intakes above requirements and 38% of them had excessive proportions of dietary fat and saturated fat. Children with higher intakes of total daily energy and total and added sugars had a greater likelihood of having impaired blood pressure and glucose/HbA1c. Childhood overweight and CM risk is prevalent in urban and rural areas of China and across different socioeconomic groups although disparities between classes still pervade. Several dietary factors such as sugars were significant correlates of CM risk.

    Full Text Available Background: Many factors can influence an athlete to consume dietary supplements, such as age, sex and sports, among others. Few studies regarding the prevalence and associated factors are available for athletes, especially in developing countries. Objective: The aim of the study was to determine the factors associated with the consumption of dietary supplements among Brazilian athletes. Material and methods: This is a cross-sectional study involving 182 athletes of both sexes. The athletes answered a questionnaire containing sociodemographic and sports information, current consumption of supplements, consumption of pharmacological substances and information on body image disorder (Body Shape Questionnaire and muscle dysmorphia (Muscle Appearance Satisfaction Scale. Analyses were performed using Pearson's Chi-squared test, the crude prevalence ratio (PR and Poisson regression with robust variance. Results: In the bivariate analysis, the male gender, age between 25-29 years, engaging in a remunerated activity, consumption of pharmacological substances, body image disorder, risk of muscle dysmorphia, power modality athletes and lack of medical care were factors associated with supplement intake. After the regression analysis, the consumption of supplements was associated with the male gender (PR: 1.68; 95% CI: 1.01; 2.78; p = 0.044, use of pharmacological substances (PR: 1.77; 95 %: 1.37; 2.27; p < 0.001 and the risk of muscle dysmorphia (PR: 1.75; 95% CI: 1.37; 2.23; p < 0.001. Conclusions: The results of this research clearly demonstrate the importance of professionals working closely with athletes to continuously monitor their use of supplements, since it was an alimentary behavior associated with other risk behavior (pharmacological use as well as image disorders (muscle dysmorphia.

    Dietary glycemic load (GL) and glycemic index (GI), indicators of the postprandial glucose and insulin response to carbohydrate composition of diet, have been suggested as independent risk factors for cardiovascular disease and diabetes. However, current knowledge about the distribution, correlates, and major contributors of these measures in human populations is limited. To describe the intakes and correlates of GL and GI in African American, Caucasian, Chinese, and Japanese women in the Study of Women's Health Across the Nation (SWAN). Data are from 2025 women participating in SWAN, a multi-ethnic, community-based cohort study of women transitioning into menopause. GL and GI were estimated from dietary information obtained in the fifth year of the study using a modified Block food frequency questionnaire. The relationship of GL and GI to dietary factors and selected demographic measures, including race/ethnicity and lifestyle factors, was examined using bivariate and multivariate analyses. GI and GL were consistently lower in Caucasian women than in African American, Japanese, or Chinese women. Education was inversely associated with GL and alcohol consumption was inversely associated with GI among all ethnic groups. The association between family income and glycemic measures varied across ethnic groups. GI was positively associated with consumption of grains and potatoes and inversely associated with consumption of fruits, juices, dairy foods, protein sources, and sweets among all ethnic groups. It is important for researchers to consider factors such as ethnicity, family income, and alcohol intake as potential confounders when investigating the associations of GL and GI with disease.

    The knowledge on the etiology of breast cancer has advanced substantially in recent years, and several etiological factors are now firmly established. However, very few new discoveries have been made in relation to occupational risk factors. The International Agency for Research on Cancer has evaluated over 900 different exposures or agents to-date to determine whether they are carcinogenic to humans. These evaluations are published as a series of Monographs (www.iarc.fr). For breast cancer the following substances have been classified as "carcinogenic to humans" (Group 1): alcoholic beverages, exposure to diethylstilbestrol, estrogen-progestogen contraceptives, estrogen-progestogen hormone replacement therapy and exposure to X-radiation and gamma-radiation (in special populations such as atomic bomb survivors, medical patients, and in-utero exposure). Ethylene oxide is also classified as a Group 1 carcinogen, although the evidence for carcinogenicity in epidemiologic studies, and specifically for the human breast, is limited. The classification "probably carcinogenic to humans" (Group 2A) includes estrogen hormone replacement therapy, tobacco smoking, and shift work involving circadian disruption, including work as a flight attendant. If the association between shift work and breast cancer, the most common female cancer, is confirmed, shift work could become the leading cause of occupational cancer in women.

    Diet composition affects organismal health. Nutrient uptake depends on the microbiome. Caenorhabditis elegans fed a Bacillus subtilis diet live longer than those fed the standard Escherichia coli diet. Here we report that this longevity difference is primarily caused by dietary coQ, an antioxidant synthesized by E. coli but not by B. subtilis. CoQ-supplemented E. coli fed worms have a lower oxidation state yet live shorter than coQ-less B. subtilis fed worms. We showed that mutations affecting longevity for E. coli fed worms do not always lead to similar effects when worms are fed B. subtilis. We propose that coQ supplementation by the E. coli diet alters the worm cellular REDOX homeostasis, thus decreasing longevity. Our results highlight the importance of microbiome factors in longevity, argue that antioxidant supplementation can be detrimental, and suggest that the C. elegans standard E. coli diet can alter the effect of signaling pathways on longevity.

    To explore the cultural factors related to dietary and fluid restriction behaviours among older Chinese patients. Excess dietary sodium and fluid intake are risk factors contributing to the worsening and rehospitalisation for heart failure in older patients. Managing the complex fluid and diet requirements of heart failure patients is challenging and is made more complicated by cultural variations in self-management behaviours in response to a health threat. Qualitative study using semi-structured in interviews and framework analysis. The design of this study is qualitative descriptive. Semi-structured in-depth interviews were conducted with 15 heart failure patients. Data were analysed through content analysis. Seven cultural themes emerged from the qualitative data: the values placed on health and illness, customary way of life, preference for folk care and the Chinese healthcare system, and factors related to kinship and social ties, religion, economics and education. Dietary change and management in response to illness, including heart failure, is closely related to individuals' cultural background. Healthcare providers should have a good understanding of cultural aspects that can influence patients' conformity to medical recommendations. Heart failure patients need support that considers their cultural needs. Healthcare providers must have a good understanding of the experiences of people from diverse cultural backgrounds. © 2016 John Wiley & Sons Ltd.

    Sustainability has become a greater concern among consumers that may influence their dietary intake. Only a few studies investigated the relationship between sustainable food choice motives and diet and they focused on specific food groups. This cross-sectional study aimed to assess the associations between food choice motives during purchasing, with a focus on sustainability, and dietary patterns in a large sample of French adults. Food choice motives were collected in 31,842 adults from the NutriNet-Santé study, using a validated 63 items questionnaire gathered into 9 dimension scores: ethics and environment, traditional and local production, taste, price, environmental limitation (i.e. not buying a food for environmental concerns), health, convenience, innovation and absence of contaminants. Dietary intake was assessed using at least three web-based 24-h food records. Three dietary patterns were obtained through factor analysis using principal component analysis. The associations between food choice motive dimension scores and dietary patterns were assessed using linear regression models, stratifying by sex. Individuals were more likely to have a "healthy diet" when they were more concerned by not buying a food for environmental concerns (only for 3(rd) tertile versus 1(st) tertile βwomen=0.18, 95% CI=0.15-0.20, βmen=0.20 95% CI=(0.15-0.25)), ethics and environment (women only, β=0.05, 95% CI=0.02-0.08), absence of contaminants (women only, β=0.05, 95% CI=0.01-0.07), local production (women only, β=0.08, 95% CI=0.04-0.11), health (women only) and innovation (men only), and when they were less concerned by price. Individuals were also less likely to have traditional or western diets when they gave importance to food choice motive dimensions related to sustainability. Individuals, especially women, having higher concerns about food sustainability dimensions such as ethics and environment and local production, appear to have a healthier diet. Further

    Background  The prevalence of overweight and obesity in children and adolescents is increasing at an alarming rate around the world and prevention has become a key public health objective. Treatment and management of those already overweight and obese must be aligned with the best available evidence on effectiveness, if the risk of obesity-related morbidity and mortality is yet be reduced. Diet plays a pivotal role in successful treatment of obesity but to date, there is limited evidence on which to base practice. Objectives  To identify and present the best available evidence on the optimal dietetic treatment and management of children and adolescent who are overweight or obese. Search strategy  Published English language literature was searched using the electronic databases CINAHL, MEDLINE, PRE-MEDLINE, DARE, COCHRANE, EMBASE, AUSTROM, Current Concepts and Dissertation Abstracts. The databases were limited to English Language from 1975 until 2003. Government reports from the UK, USA and Australian were also searched and a hand search performed for the Journal of the Dietitians Association of Australia, International Journal of Obesity and the Journal of Human Nutrition and Dietetics and the bibliographies of retrieved articles. Selection criteria  (i) Interventions that evaluated the effectiveness of nutrition or dietary interventions to treat or manage overweight and obesity; (ii) Children aged less than 18 years; and (iii) Participants were defined as overweight or obese by relative weight or a measure of body weight status, studies that reported body weight per se were excluded. Data collection and analysis  An experienced professional librarian searched the databases, and two trained research assistants independently identified studies for retrieval and assessed each article for inclusion. The included studies were critically appraised for methodological quality by two people independently. Data were extracted from the appropriate articles and

  1. Tolerance of Broiler to Dietary Soybean Antinutritional Factors

    2001-01-01

    Raw, heat treated soybean meal and diets made from soybeans extruded at varying temperature were compared to examine dietary threshold levels of the major soybean antinutritional factors (ANF)for broilers.Whole full-fat soybeans were extruded at 90,100,110,120,130,or 140 C. An in vivo nutritional evaluation of the extruded soybean meals was carried out using 224 Arbor Acres broilers allotted to seven treatments with four replicates of eight birds per pen. As extrusion cooking temperature increased,the urease activity,TI activity,lectin content and PDI decreased. Extruding at 120 C reduced the urease actvity to 0.11 units.the TI activity to 7.20 mg@ g-1 ,and lectin content to zero. Raw soybean meal significantly depressed the growth rate of broiler chickens. Remaining ANF obviously reduced feed intake and dietary nitrogen metabolism. The performance of broilers was improved as extrusion temperature increased. Extruding at 110 C produced an effect equal to that of conventional soybean meal. The weight of the pancreas of the birds fed the raw soybean or 90C-extruded soybean were significantly higher than those in heated-soybean meal group and in the higher temperature-extruded soyean groups. The same tendency was found from 3 to 7 wk of age. The weights of duodenum and ileum of the broilers fed the raw soybean were significantly higher than those in heated-soybean meal group. Extending the feeding of raw soybean or low temperature-extruded soybean to 7-wk-old hroilers significantly increased the fresh weights of proventriculus,jejunum and ileum and dry weights of jejunum and ileum. The villi of birds fed raw soybean meal and low-temperature-extruded soybean meals were shot tened and damaged. Broilers grew well on the diets containing soybean trypsin inhitory activity as high as 3.74 mg @ g-1 without showing any negative effect on the weights of organs and alimentary tracts.

    Objective: To find out the dietary patterns and explore the relationship between environmental factors (especially dietary patterns) and diabetes mellitus in the adults of Fujian. Methods: Multi-stage sampling method were used to survey residents aged ≥18 years by questionnaire, physical examination and laboratory detection in 10 disease surveillance points in Fujian. Factor analysis was used to identify the dietary patterns, while logistic regression model was applied to analyze relationship between dietary patterns and diabetes mellitus, and classification tree model was adopted to identify the influencing factors for diabetes mellitus. Results: There were four dietary patterns in the population, including meat, plant, high-quality protein, and fried food and beverages patterns. The result of logistic analysis showed that plant pattern, which has higher factor loading of fresh fruit-vegetables and cereal-tubers, was a protective factor for non-diabetes mellitus. The risk of diabetes mellitus in the population at T2 and T3 levels of factor score were 0.727 (95%CI:0.561-0.943) times and 0.736 (95%CI: 0.573-0.944) times higher, respectively, than those whose factor score was in lowest quartile. Thirteen influencing factors and eleven group at high-risk for diabetes mellitus were identified by classification tree model. The influencing factors were dyslipidemia, age, family history of diabetes, hypertension, physical activity, career, sex, sedentary time, abdominal adiposity, BMI, marital status, sleep time and high-quality protein pattern. Conclusion: There is a close association between dietary patterns and diabetes mellitus. It is necessary to promote healthy and reasonable diet, strengthen the monitoring and control of blood lipids, blood pressure and body weight, and have good lifestyle for the prevention and control of diabetes mellitus.

    Full Text Available BACKGROUND As India is considered as the diabetic capital of the world, a huge burden of undiagnosed Metabolic Syndrome (MetS is a possibility. Early intervention can be planned if MetS can be detected early along with risk factor assessment to avert cardiovascular morbidities. The aim of this study was to assess the dietary risk factor of metabolic syndrome. MATERIALS AND METHODS Community based cross-sectional study was conducted in Dibrugarh District of Assam with multistep sampling. Study area, i.e. four rural sub-centres and two urban electoral blocks were selected randomly. From the list of population of selected area, the consenting eligible were included. Sample size was 1700 population with MetS. Socio-demographic information, World Health Organisation’s STEPS questionnaire for behavioural risk factors along with dietary history, anthropometric assessment and laboratory investigations were conducted in three stages. Food frequency questionnaire was used for dietary assessment. Statistical analysis was done using rates, ratio, proportion, univariate and multivariate analysis. RESULTS MetS was 47.6% (1606 of 3372 screened. Mean age of study population was 47.1 ± 10.9 years. Behavioural risk factors like tobacco, alcohol consumption was high and significantly associated with metabolic syndrome (p= 0.000. Similarly financial stress, feeling stressed in last one year (p=0.034, lower physical activity level were also significantly associated with metS (p=0.000. Consumption of meat (p=0.000, egg (p=0.000, fast food (p=0.000, pickled vegetable (p=0.000 and sweet snacks (p=0.000 was found significantly higher amongst those with metabolic syndrome. Significant association was also seen with number of meals served per day and metS (p=0.000. CONCLUSION Dietary risk factors of cardiovascular diseases were rampant amongst persons with MetS. Dietary risk factor survey and counselling on healthy diet can be implemented in these population to give

    The association between diet and prostate cancer (PC) risk, although suggestive, still remains largely elusive particularly in the Asian population. This study sought to further evaluate the possible effects of different dietary factors on risk of PC in Iran. Using data from a prospective hospital-based multicenter case-control study, dietary intakes of red meat, fat, garlic, and tomato/tomato products, as well as thorough demographic and medical characteristics, were determined in 194 cases with the newly diagnosed, clinicopathologically confirmed PC and 317 controls, without any malignant disease, admitted to the same network of hospitals. Odds ratios (ORs) and corresponding 95% confidence intervals (CIs) were obtained after adjustment for major potential confounders, including age, body mass index, smoking, alcohol, education, occupation, family history of PC, and total dietary calories. Comparing the highest with the lowest tertile, a significant trend of increasing risk with more frequent consumption was found for dietary fat (OR: 1.79, 95% CI: 1.71-4.51), whereas inverse association was observed for tomato/tomato products (OR: 0.33, 95% CI: 0.16-0.65). A nonsignificant increase in PC risk was revealed for dietary red meat (OR: 1.69, 95% CI: 0.93-3.06). For garlic consumption, a borderline reduction in risk was observed (OR: 0.58, 95% CI: 0.32-1.01; P = 0.05). In conclusion, our study supports the hypothesis that total fat may increase PC risk and tomatoes/tomato products and garlic may protect patients against PC.

Total phthalate concentration was examined in fasting morning urine samples. Socio-demographic and lifestyle factors were assessed by questionnaire. Food intake was assessed by food frequency questionnaire (FFQ. Dietary patterns were constructed using factor analysis.Total phthalates were detected in 99.6% of the urine samples. The overall geometric mean (95% CI of total phthalate concentration was 112.4 (107.5-117.5 ng/mL. The least square geometric means (LSGMs of total phthalate concentration were significantly higher among people who were obese (127.8 ng/mL, consuming less than two serves fruit per day (125.7 ng/mL and drinking more than one can (375mL of carbonated soft drink per day (131.9 ng/mL. Two dietary patterns were identified: a prudent dietary pattern and a western dietary pattern. Both the western dietary pattern (p = 0.002 and multiple lifestyle risk factors including smoking, obesity, insufficient physical activity and the highest quartile of the western dietary pattern (p<0.001, were positively associated with total phthalate levels. There was no significant relationship between total phthalate concentration and socio-demographic status.Phthalate exposure is ubiquitous and positively associated with lifestyle risk factors in urban dwelling Australian men.

    The aim of this study was to compare the clinical characteristics of "pure" uric acid renal stone formers (UA-RSFs) with that of mixed uric acid/calcium oxalate stone formers (UC-RSFs) and to identify which urinary and dietary risk factors predispose to their formation. A total of 136 UA-RSFs and 115 UC-RSFs were extracted from our database of renal stone formers. A control group of 60 subjects without history of renal stones was considered for comparison. Data from serum chemistries, 24-h urine collections and 24-h dietary recalls were considered. UA-RSFs had a significantly (p = 0.001) higher body mass index (26.3 ± 3.6 kg/m(2)) than UC-RSFs, whereas body mass index of UA-RSFs was higher but not significantly than in controls (24.6 ± 4.7) (p = 0.108). The mean urinary pH was significantly lower in UA-RSFs (5.57 ± 0.58) and UC-RSFs (5.71 ± 0.56) compared with controls (5.83 ± 0.29) (p = 0.007). No difference of daily urinary uric acid excretion was observed in the three groups (p = 0.902). Daily urinary calcium excretion was significantly (p = 0.018) higher in UC-RSFs (224 ± 149 mg/day) than UA-RSFs (179 ± 115) whereas no significant difference was observed with controls (181 ± 89). UA-RSFs tend to have a lower uric acid fractional excretion (0.083 ± 0.045% vs 0.107+/-0.165; p = 0.120) and had significantly higher serum uric acid (5.33 ± 1.66 vs 4.78 ± 1.44 mg/dl; p = 0.007) than UC-RSFs. The mean energy, carbohydrate and vitamin C intakes were higher in UA-SFs (1987 ± 683 kcal, 272 ± 91 g, 112 ± 72 mg) and UC-SFs (1836 ± 74 kcal, 265 ± 117, 140 ± 118) with respect to controls (1474 ± 601, 188 ± 84, 76 ± 53) (p = 0.000). UA-RSFs should be differentiated from UC-RSFs as they present lower urinary pH, lower uric acid fractional excretion and higher serum uric acid. On the contrary, patients with UC-RSFs show urinary risk factors

    However, the incidence of gastric cancer (GC) has been decreased in past decades; GC is the second cause of cancer related death in the world. Evidence has illustrated that several factors including Helicobacter pylori (H. pylori) infection, host genetics, and environmental factors (smoking and particularly diet) may play a crucial role in gastric carcinogenesis. It has been demonstrated that high consumption of fresh fruits, vegetables, high level of selenium and zinc in drinking water, sufficient iron, and cholesterol protect against GC, while; smoked , pickled, and preserved foods in salt, and nitrites increase the risk of GC. Epidemiological studies have also proved that H. pylori infection and a high salt diet could independently induce atrophic gastritis and intestinal metaplasia. Recently, studies have been demonstrated that dietary factors directly influence H. pylori virulence. The use of appropriate diet could reduce levels of H. pylori colonization or virulence and prevent or delay development of peptic ulcers or gastric carcinoma. This is attractive from a number of perspectives including those of cost, treatment tolerability, and cultural acceptability. This review will describe new insights into the pathogenesis of H. pylori in relation to environmental factors, especially dietary, not only to find the developed means for preventing and treating GC, but also for understanding the role of chronic inflammation in the development of other malignancies.

    2011-03-01

    Over 50 years of research has sought to define the role dietary fat plays in cardiovascular disease (CVD) risk. Although optimal dietary fat quantity has been keenly pursued over past decades, attention has recently centered on the value of dietary fat quality. The purpose of the present review is to provide a critical assessment of the current body of evidence surrounding efficacy of dietary monounsaturated fatty acids (MUFA) for reduction of traditional risk factors defining metabolic syndrome (MetS) and CVD. Due to existing and emerging research on health attributes of MUFA rich diets, and to the low prevalence of chronic disease in populations consuming MUFA rich Mediterranean diets, national dietary guidelines are increasingly recommending dietary MUFA, primarily at the expense of saturated fatty acids (SFA). Consumption of dietary MUFA promotes healthy blood lipid profiles, mediates blood pressure, improves insulin sensitivity and regulates glucose levels. Moreover, provocative newer data suggest a role for preferential oxidation and metabolism of dietary MUFA, influencing body composition and ameliorating the risk of obesity. Mounting epidemiological and human clinical trial data continue to demonstrate the cardioprotective activity of the MUFA content of dietary fat. As the debate on the optimal fatty acid composition of the diet continues, the benefit of increasing MUFA intakes, particularly as a substitute for dietary SFA, deserves considerable attention.

    Reduced dietary sodium intake (sodium reduction) increases heart rate in some studies of animals and humans. As heart rate is independently associated with the development of heart failure and increased risk of premature death a potential increase in heart rate could be a harmful side-effect of sodium reduction. The purpose of the present meta-analysis was to investigate the effect of sodium reduction on heart rate. Relevant studies were retrieved from an updated pool of 176 randomized controlled trials (RCTs) published in the period 1973-2014. Sixty-three of the RCTs including 72 study populations reported data on heart rate. In a meta-analysis of these data sodium reduction increased heart rate with 1.65 beats per minute [95% CI: 1.19, 2.11], p sodium reduction increases heart rate by as much (2.4%) as it decreases blood pressure (2.5%). This side-effect, which may cause harmful health effects, contributes to the need for a revision of the present dietary guidelines.

    This study was performed to identify dietary patterns in Korean men and to determine the associations among dietary patterns, nutrient intake, and health-risk factors. Using baseline data from the Korean Health and Genome Study, dietary patterns were identified using factor analysis of data from a validated food-frequency questionnaire, and associations between these dietary patterns and health-risk factors were analyzed. Three dietary patterns were identified: 1) the "animal-food" pattern (greater intake of meats, fish, and dairy products), 2) the "rice-vegetable" pattern (greater intake of rice, tofu, kimchi, soybean paste, vegetables, and seaweed), and 3) the "noodle-bread" pattern (greater intake of instant noodles, Chinese noodles, and bread). The animal-food pattern (preferred by younger people with higher income and education levels) had a positive correlation with obesity and hypercholesterolemia, whereas the rice-vegetable pattern (preferred by older people with lower income and educational levels) was positively associated with hypertension. The noodle-bread pattern (also preferred by younger people with higher income and education levels) had a positive association with abdominal obesity and hypercholesterolemia. This study identifies three unique dietary patterns in Korean men, which are independently associated with certain health-risk factors. The rice-vegetable dietary pattern, modified for a low sodium intake, might be a healthy dietary pattern for Korean men. Copyright © 2011 Elsevier Inc. All rights reserved.

    Malnutrition is conditioned by a series of factors, among them the dietary factors, which include appetite, eating behaviors and habits. In order to assess these factors, the following objective was pursued: describe the dietary factors and their relation to appetite in children under two years of age with mild malnutrition. A correlational study was conducted. The sample consisted of all children under two years of age (n = 168) diagnosed with primary (mild) malnutrition, who attended consultation at the Centro de Atención Nutricional Infantil Antímano, CANIA, during the period 2000-2008. The results showed intake of energy and macronutrients was lower than the individual requirement; iron intake children showed rebellious behavior and caregivers were permissive. Protein adequacy, vegetable and whole milk consumption frequency, preparation type, identification of refusals and preferences, place and duration of meals, and child-caregiver interaction at mealtimes were significantly associated with appetite; if we consider this last one as a guide and we try to modify inadequate eating behaviors and habits, we will generate an impact over the child appetite that could improve the food consumption and prevent malnutrition.

    The study gives a survey of the factors most frequently mentioned in the literature as factors likely to adversely affect a pregnancy. One essential aspect is the discussion of those factors that can be counted among the causes of malformations, as among others, prenatal radiation exposure. The study prepared within the framework of the research project `Radiobiological environmental monitoring in Bavaria` is intended to serve as a basis for a retrospective and prospective evaluation of infant mortality, perinatal conditions and occurrence of malformations in Bavaria, with the principal idea of drawing up an environment - related health survey. The study therefore, in addition to ionizing radiation also takes into account other detectable risks within the ecologic context, as e.g. industrial installations, refuse incineration plants or waste dumps, or urbanity. (orig./MG). [Deutsch] In der vorliegenden Arbeit wird ein Ueberblick ueber die haeufigsten in der Literatur beschriebenen Faktoren, die einen unguenstigen Einfluss auf den Schwangerschaftsverlauf ausueben koennen, gegeben. Ein Hauptgewicht liegt dabei auf der Beschreibung von solchen Faktoren, die mit der Induktion von Fehlbildungen in Zusammenhang gebracht werden koennen, so unter anderem auch der praenatalen Strahlenexposition. Diese Arbeit, die im Rahmen des Forschungsvorhabens `Strahlenbiologisches Umweltmonitoring Bayern` angefertigt wurde, bildet die Grundlage einer im Sinne einer umweltbezogenen Gesundheitsberichterstattung retro- bzw. prospektiv angelegten Auswertung der Saeuglingssterblichkeit, des Perinatalgeschehens und der Fehlbildungshaeufigkeit in Bayern, wobei neben der ionisierenden Strahlung als Risikofaktor auch andere im Rahmen einer oekologischen Studie erfassbare Risiken, wie beispielsweise Industrieansiedlungen, Muellverbrennungsanlagen und -deponien oder Urbanitaet beruecksichtigt werden sollen.

    Data available on the effect of quality (glycemic index [GI]) and quantity (glycemic load [GL]) of carbohydrates on the risk factors of cardiovascular disease (CVD) are inconsistent. The objective of this study was to examine the association between dietary GI, GL, and CVD risk factors among Tehranian adults, the participants of the Tehran Lipid and Glucose Study. This population- based cross-sectional study was conducted on 2457 subjects (46% men and 54% women), aged 19 to 84 years. Dietary GI and GL were measured using a validated 168- item semiquantitative food frequency questionnaire. Anthropometrics, blood pressure, fasting blood glucose, and lipid profiles were measured. The mean intakes of GI and GL were 68.3 and 244.8, respectively. Rice (26.6%) and bread (19.0%) were the major contributors to dietary GI and GL, respectively. Higher dietary GI and GL were associated with high intakes of carbohydrate, fiber, refined grain, fruits, simple sugar, snack, and desserts. After adjustment for lifestyle and dietary variables, a higher dietary GI was positively associated with triglycerides and high-density lipoprotein (HDL) cholesterol concentrations among obese subjects. Dietary GL was positively associated with fasting and 2-h blood glucose among nonobese subjects, after adjustment for confounders.   Dietary GI and GL were associated with a few CVD risk factors, and body mass index levels may modulate these associations.

    The consumption of instant noodles is relatively high in Asian populations. It is unclear whether a higher intake of instant noodles is associated with cardiometabolic risk independent of overall dietary patterns. We therefore investigated the association using the Korean National Health and Nutrition Examination Survey IV 2007-2009, a nationally representative cross-sectional survey of the Korean population with a clustered, multistage, stratified, and rolling sampling design. A total of 10,711 adults (54.5% women) 19-64 y of age were analyzed, with adjustment for sampling design complexity. Diet was assessed by using a 63-item food-frequency questionnaire. We identified 2 major dietary patterns with the use of principal components analysis: the "traditional dietary pattern" (TP), rich in rice, fish, vegetables, fruit, and potatoes, and the "meat and fast-food pattern" (MP), with less rice intake but rich in meat, soda, fried food, and fast food including instant noodles. The highest MP quintile was associated with increased prevalence of abdominal obesity (OR: 1.41; 95% CI: 1.05, 1.90), LDL cholesterol ≥130 mg/dL (1.3 g/L) (OR: 1.57, 95% CI 1.26, 1.95), decreased prevalence of low HDL cholesterol (OR: 0.65; 95% CI: 0.53, 0.80), and high triglycerides [≥150 mg/dL (1.5 g/L); OR: 0.73; 95% CI: 0.57, 0.93]. The highest quintile for the TP was associated with decreased prevalence of elevated blood pressure (OR: 0.73; 95% CI: 0.59, 0.90) and marginally lower trends for abdominal obesity (OR: 0.76; 95% CI: 0.58, 0.98; P-trend = 0.06), but neither of the dietary patterns was associated with prevalence of metabolic syndrome. The consumption of instant noodles ≥2 times/wk was associated with a higher prevalence of metabolic syndrome (OR: 1.68; 95% CI: 1.10, 2.55) in women but not in men (OR: 0.93; 95% CI: 0.58, 1.49; P-interaction = 0.04). The 2 major dietary patterns were associated with distinct cardiometabolic risk factors. The consumption of instant noodles was

    Full Text Available Objective. A shift in the total incidence from left- to right-sided colon cancer has been reported and raises the question as to whether lifestyle risk factors are responsible for the changing subsite distribution of colon cancer. The present study provides a review of the subsite-specific risk estimates for the dietary components presently regarded as convincing or probable risk factors for colorectal cancer: red meat, processed meat, fiber, garlic, milk, calcium, and alcohol. Methods. Studies were identified by searching PubMed through October 8, 2012 and by reviewing reference lists. Thirty-two prospective cohort studies are included, and the estimates are compared by sex for each risk factor. Results. For alcohol, there seems to be a stronger association with rectal cancer than with colon cancer, and for meat a somewhat stronger association with distal colon and rectal cancer, relative to proximal colon cancer. For fiber, milk, and calcium, there were only minor differences in relative risk across subsites. No statement could be given regarding garlic. Overall, many of the subsite-specific risk estimates were nonsignificant, irrespective of exposure. Conclusion. For some dietary components the associations with risk of cancer of the rectum and distal colon appear stronger than for proximal colon, but not for all.

    Full Text Available BACKGROUND: Information on dietary supplement (DS use during pregnancy is largely lacking. Besides, little is known about the share of DS use as self-medication versus such use following a physician's advice/prescription. Our aim was to evaluate DS use and its socioeconomic, lifestyle and dietary correlates among pregnant women participating in the French NutriNet-Santé cohort study. METHOD: Data were collected by self-administered web-based questionnaires. Food intake was assessed by repeated 24 h dietary records. 903 pregnant women provided data on their DS use (both "regular" DS and medication containing mainly vitamins/minerals. Supplement users were compared to non-users by unconditional logistic regression. RESULTS: DS use-in general and as regards folic acid in particular-was positively correlated with age, being primiparous, having higher income and belonging to a higher socioprofessional category. DS users had significantly higher dietary intakes of most vitamins and minerals. The proportion of DS users (e.g., those reporting use at least three days a week increased significantly with the trimester of pregnancy (58.0%, 62.2% and 74.5%, respectively. 50.2% of women in their 1st trimester used folic acid. The proportion of iron users tripled from the 1st to the 3rd trimester (18.5 to 63.9%. DS use was prescribed or recommended by a physician in 86.7% of the cases. CONCLUSION: This study provided new and detailed information on DS use and its correlates during pregnancy. Even in this relatively well-educated population, folic acid supplementation at the beginning of pregnancy was inadequate and was associated with socioeconomic and demographic disparities.

    Dietary fiber is beneficial for the treatment of type 2 diabetes mellitus, although it is consumed differently in ethnic foods around the world. We investigated the association between dietary fiber intake and obesity, glycemic control, cardiovascular risk factors and chronic kidney disease in Japanese type 2 diabetic patients. A total of 4,399 patients were assessed for dietary fiber intake using a brief self-administered diet history questionnaire. The associations between dietary fiber intake and various cardiovascular risk factors were investigated cross-sectionally. Body mass index, fasting plasma glucose, HbA1c, triglyceride and high-sensitivity C-reactive protein negatively associated with dietary fiber intake after adjusting for age, sex, duration of diabetes, current smoking, current drinking, total energy intake, fat intake, saturated fatty acid intake, leisure-time physical activity and use of oral hypoglycemic agents or insulin. The homeostasis model assessment insulin sensitivity and HDL cholesterol positively associated with dietary fiber intake. Dietary fiber intake was associated with reduced prevalence of abdominal obesity, hypertension and metabolic syndrome after multivariate adjustments including obesity. Furthermore, dietary fiber intake was associated with lower prevalence of albuminuria, low estimated glomerular filtration rate and chronic kidney disease after multivariate adjustments including protein intake. Additional adjustments for obesity, hypertension or metabolic syndrome did not change these associations. We demonstrated that increased dietary fiber intake was associated with better glycemic control and more favorable cardiovascular disease risk factors including chronic kidney disease in Japanese type 2 diabetic patients. Diabetic patients should be encouraged to consume more dietary fiber in daily life.

    Little is known about the relationship of dietary cost to health status. The present cross-sectional study examined the association between the monetary cost of dietary energy (Japanese yen/4184 kJ) and several metabolic risk factors. Monetary cost of dietary energy was estimated based on dietary intake assessed by a self-administered diet history questionnaire and retail food prices. Body height and weight, from which BMI was derived, waist circumference and blood pressure were measured and fasting blood samples were collected for biochemical measurements. A total of fifteen universities and colleges in Japan. A total of 1136 female Japanese dietetic students aged 18-22 years. After adjustment for potential confounding factors, monetary cost of dietary energy was significantly and negatively associated with BMI (P for trend = 0.0024). Monetary cost of dietary energy also showed a significant and negative association with waist circumference independently of potential confounding factors, including BMI (P for trend = 0.0003). No significant associations were observed for other metabolic risk factors examined (P for trend = 0.10-0.88). The monetary cost of dietary energy was independently and negatively associated with both BMI and waist circumference, but not other metabolic risk factors, in a group of young Japanese women.

    Objective Given the public health importance of improving dietary behavior in chronic disease prevention in low- and middle-income countries it is crucial to understand the factors influencing dietary behavior in these settings. This study tested the validity of a conceptual framework linking individual and environmental factors to dietary behavior among Ecuadorian adolescents aged 10–16 years. Methods A cross-sectional survey was conducted in 784 school-going Ecuadorian adolescents in urban and rural Southern Ecuador. Participants provided data on socio-economic status, anthropometry, dietary behavior and its determining factors. The relationships between individual (perceived benefits and barriers, self-efficacy, habit strength, and a better understanding of healthy food) and environmental factors (physical environment: accessibility to healthy food; social environment: parental permissiveness and school support), and their association with key components of dietary behavior (fruit and vegetables, sugary drinks, breakfast, and unhealthy snack intake) were assessed using structural equation modeling. Results The conceptual model performed well for each component of eating behavior, indicating acceptable goodness-of-fit for both the measurement and structural models. Models for vegetable intake and unhealthy snacking showed significant and direct effects of individual factors (perceived benefits). For breakfast and sugary drink consumption, there was a direct and positive association with socio-environmental factors (school support and parental permissiveness). Access to healthy food was associated indirectly with all eating behaviors (except for sugary drink intake) and this effect operated through socio-environmental (parental permissiveness and school support) and individual factors (perceived benefits).

    2016-04-01

    The scope of this study was to conduct a systematic review to establish the major dietary habits of adolescents and the corresponding association with cardiovascular risk factors. Research was performed in the LILACS, SciELO, PubMed, Scopus and Web of Science databases in addition to a manual search for original articles published between 2005 and 2014. Of the 371 entries identified; 26 fulfilled the inclusion criteria and were covered in the review. The main dietary habits observed were Western (61%) Healthy (42%) and Traditional (38%). Western dietary habits were positively associated with total cholesterol and SM, while Healthy dietary habits were inversely associated with fasting glycaemia, DBP and SM and positively with HDL-C, all of the aforementioned associations with very low (D) quality of evidence in accordance with the GRADE rating. The Traditional dietary habits were considered a risk factor for hyperglycemia, hyperinsulinemia and hypertriglyceridemia and protection for physical activity and eutrophic BMI. Although these results need to be analyzed with caution, due to the low quality of evidence, there is a clear need for actions aimed at promoting healthy dietary habits in adolescents in order to contribute to the prevention of cardiovascular risk factors.

    Full Text Available Obesity is a growing health problem in developed nations and in countries that are in the process of westernization like India. Obesity is linked with several health disorders such as hypertension and cardiovascular diseases, Type 2 diabetes, dyslipidemia and certain cancers. Currently, obesity-related malignancies, e.g., cancers of the breast, prostate and colon are the leading cancers in the industrialized societies. An increased amount of fat or adipose tissue in an overweight or obese person probably influences the development of cancer by releasing several hormone-like factors or adipokines. The majority of adipokines are pro-inflammatory, which promote pathological conditions like insulin resistance and cancer. On the other hand, many recent studies have shown that adiponectin, an anti-inflammatory adipokine, has anti-cancer and insulin-sensitizing effects. Adiponectin exerts its physiological functions chiefly by activation of AMP kinase via adiponectin receptors. Interestingly, several fruits and vegetables may contain adiponectin-like molecules or may increase the biosynthesis of adiponectin in our body. Studies on adiponectin analogues or adiponectin receptor agonists are a promising area of cancer chemoprevention research. In general, fruits and vegetables contain various dietary substances such as vitamins, minerals (like calcium and selenium, fiber and phytochemicals or phenolic compounds (like flavonoids and vanilloids, which may act as anti-cancer agents. Similarly, several dietary constituents including phytochemicals may have anti-obesity effects. Consumption of such dietary compounds along with caloric restriction and physical activity may be helpful in preventing obesity-related cancers. For this review article, we searched PubMed primarily to get the relevant literature.

    To better understand the relationship between dietary factors and thyroid cancer risk, we summarized the published evidence on relationship between dietary factors and thyroid cancer incidence. Searching several databases for relevant studies published by March 2014 included a total of 19 studies. We calculated summary odds ratios (ORs) for each risk factor. Based on the highest level of total consumption vs. the lowest level, the summary OR [95% (confidence interval) CI] of thyroid cancer was 0.79 (0.66, 0.94) for fish; 0.95 (0.74, 1.23) for salt water fish; 0.86 (0.63, 1.16) for fresh water fish; 0.76 (0.58, 1.00) for vegetables; 0.88 (0.72, 1.08) for shellfish; 0.93 (0.66, 1.29) for cruciferous vegetables; 0.97 (0.78, 1.21) for fruits; 0.96 (0.70, 1.34) for meat; and 1.11 (0.86, 1.42) for grains. Subgroup analysis showed that fish (OR 0.74, 95%CI: 0.59, 0.92) and shellfish (OR 0.46, 95%CI: 0.27, 0.75) consumption have a protective effect in iodine deficiency areas, whereas the ORs were not statistically significant in iodine-rich areas. Our findings indicated that fish and shellfish consumption may decrease the risk of thyroid cancer in iodine deficiency areas, although no such effect was observed in iodine-rich areas.

    AIM: Although epidemiological and experimental studies validate influence of genetic, environmental and dietary factors in the causation of various types of cancers including colon, results from all these sources are inconclusive.Hypothesizing that high fat diet and obesity are among the major predisposing factors in the incidence of colon cancer,we evaluated the role of diet constituted with food material derived from a tropical plant, Tamarindus indica Linn (TI).METHODS: A two part randomized double-blind study was conducted employing inbred Swiss albino mice from a single generation for the whole investigation. One day-old neonates (n = 12) were subcutaneously administered with monosodium glutamate (MSG) to induce obesity (OB). At weaning these animals were maintained on modified AIN-76 diet supplemented with 10% TI and 10% fat bolus (w/w, TIFB) for 8 wk. Subsequently, in the second part of study, four groups of animals belonging to the same generation, age and gender (n = 12 per group), were maintained on: AIN-76 control diet (CD); AIN-76 mixed with 10% TI extract (TI); and, mixed with 10% TI and 10% FB (TIFB) for 8 wk, to determine intestinal crypt cell proliferation, functionally-specific enzyme activities,fermentation profile, and energy preferences.RESULTS: We observed a significant increase in the crypt cell production rate in distal colonic segment of experimental animals when compared with the controls. This segment also contained significantly low butyrate levels compared to control and TIFB groups. All the experimental groups showed a gross decrease in the enzyme activities viz.,succinate dehydrogenase, acid-galactosidase and dipeptidyl amino peptidase Ⅳ demonstrating pathological stress caused by the test regimens, and an altered metabolic flux in the cellular environment.CONCLUSION: We have demonstrated a cumulative response to the three dietary factors, one of which (TI) is reported, herein, for the first time to modulate kinetics of large

    Full Text Available BACKGROUND: The association of dietary pattern with chronic diseases has been investigated widely in western countries. However, information is quite limited among children in China. Our study is aimed to identify the dietary patterns of Chinese children and examine their association with obesity and related cardiometabolic risk factors. METHODS: A total of 5267 children were selected using multistage random sampling from 30 primary schools of 5 provincial capital cities in China. Dietary intake was derived from 24 hour dietary recall for three consecutive days. Anthropometric measurements, glucose and lipid profiles were obtained. Factor analysis combined with cluster analysis was used for identifying major dietary patterns. The associations of dietary patterns with obesity and related cardiometabolic risk factors were examined by logistic regression analysis. RESULTS: Three mutually exclusive dietary patterns were identified, which were labeled as the healthy dietary pattern, the transitive dietary pattern, and the Western dietary pattern. Compared with children of the healthy dietary pattern, the multiple-adjusted odds ratios (95% confidence interval (CI of obesity were 1.11 (0.89-1.38 for children with the transitive dietary pattern and 1.80 (1.15-2.81 for children with the Western dietary pattern, which was 1.31 (95%CI 1.09-1.56 and 1.71 (95%CI: 1.13-2.56, respectively, for abdominal obesity. The Western dietary pattern was associated with significantly higher concentrations of low-density lipoprotein cholesterol (P<.001, triglycerides (P<.001, systolic blood pressure (P = 0.0435 and fasting glucose (P = 0.0082 and a lower concentration of high-density lipoprotein cholesterol (P = 0.0023, as compared with the healthy dietary pattern. CONCLUSIONS: The Western dietary pattern characterized by red meat, eggs, refined grain and products, was positively associated with odds of obesity, the levels of plasma glucose, low-density lipoprotein

    To ascertain the major dietary patterns in the cohort 'SUN' and to assess the association of several sociodemographic (including age and gender) and lifestyle variables with the adherence to these dietary patterns. This study is a cross-sectional analysis of 3847 subjects (1587 men and 2260 women) belonging to a prospective cohort study based on self-reported questionnaires. A factor analysis based on 30 predefined food groups was conducted to ascertain the major dietary patterns in the cohort. Multiple regression models were fitted to assess the relationship between several sociodemographic and lifestyle variables and the adherence to these dietary patterns (measured using two scores with observed values ranging from -3.2 to +4.6 for the Western pattern and -3.1 to +5.5 for the Mediterranean pattern). Two major dietary patterns were found. The first pattern was labelled as a 'Western' dietary pattern and the other as a 'Spanish-Mediterranean' dietary pattern. Younger subjects were more likely to follow a 'Western' dietary pattern; the coefficient representing the change for every 10 y increase in age was b=-0.24 (P<0.001) for men and b=-0.12 (P<0.001) for women. More physically active subjects were less likely to follow a 'Western' dietary pattern and more likely to follow a 'Spanish-Mediterranean' dietary pattern. An association between a higher level of physical activity during leisure time and adherence to a 'Spanish-Mediterranean' diet was apparent. However, the profile of being a young, sedentary and single male was identified as the most likely to exhibit a departure from the traditional 'Spanish-Mediterranean' diet and follow a 'Western' dietary pattern.

    Studies on diet quality among individuals with type 2 diabetes mellitus (T2DM) are scarce. This crosssectional study aimed to assess the diet quality and to determine its associated factors among individuals with T2DM at the Medical Outpatients Department, Serdang Hospital, Selangor, Malaysia, from July 2010 to March 2011. Subjects were interviewed for sociodemographic data. Diabetes history was retrieved from the hospital's e-database. Usual dietary intake was measured using a food frequency questionnaire, from which a dietary diversity score was obtained with two measures: Food Group Score and Serving Score were constructed based on the Malaysian Dietary Guidelines. Food Group Score was computed from the number of food groups consumed from five major food groups (grains, vegetables, fruits, meat, and dairy products) whereas Serving Score was computed from the number of servings consumed from the various food groups. Anthropometric measures, including weight, height, waist- and hip-circumference were examined. For data analyses, descriptive statistics, simple and multiple linear regression were conducted using IBM SPSS Statis- tics 20.0. A total of 113 subjects (50.4% female), with mean?SD age of 54.05 +/- 10.30 years and duration of diabetes of 11.25?9.05 years were studied. The mean Food Group Score and Serving Score were 4.12 +/- 0.79 and 12.75+3.50 respectively. Slightly more than one-third of the subjects achieved five food groups a day while less than 2% consumed a desirable number of servings from all food groups. Among the five food groups, dairy, and fruits were the least-frequently consumed foods. Lower education, lower personal income, working, non-insulin, overweight and obese subjects had significantly lower Food Group Score than their counterparts [F (6,106)=4.924, pnational dietary guidelines. The importance of taking a well-balanced diet in accordance with the guidelines should be emphasized, especially among those with lower educational level

    Full Text Available This study aimed to investigate the effects of factor rotation methods on interpretability and construct validity of dietary patterns derived in a representative sample of 1,102 Brazilian adults. Dietary patterns were derived from exploratory factor analysis. Orthogonal (varimax and oblique rotations (promax, direct oblimin were applied. Confirmatory factor analysis assessed construct validity of the dietary patterns derived according to two factor loading cut-offs (≥ |0.20| and ≥ |0.25|. Goodness-of-fit indexes assessed the model fit. Differences in composition and in interpretability of the first pattern were observed between varimax and promax/oblimin at cut-off ≥ |0.20|. At cut-off ≥ |0.25|, these differences were no longer observed. None of the patterns derived at cut-off ≥ |0.20| showed acceptable model fit. At cut-off ≥ |0.25|, the promax rotation produced the best model fit. The effects of factor rotation on dietary patterns differed according to the factor loading cut-off used in exploratory factor analysis.

    Full Text Available Abstract Background Obesity develops when energy intake continuously exceeds energy expenditure, causing a fundamental chronic energy imbalance. Societal and behavioural changes over the last decades are held responsible for the considerable increase in sedentary lifestyles and inappropriate dietary patterns. The role of dietary fat and other dietary factors in the aetiology and maintenance of excess weight is controversial. The purposes of the present study were to investigate the dietary factors associated with body mass index (BMI and waist circumference (WC, and to analyse whether dietary intake varies between subjects with different levels of sports participation. Methods Data for this cross-sectional study, including anthropometric measurements, 3-day diet diary and physical activity questionnaire, were collected by the Flemish Policy Research Centre Sport, Physical Activity and Health (SPAH between October 2002 and April 2004. Results of 485 adult men and 362 women with plausible dietary records were analysed. Analyses of covariance were performed to determine the differences in dietary intake between normal weight, overweight and obese subjects, and between subjects with different levels of sports participation. Results Total energy intake, protein and fat intake (kcal/day were significantly higher in obese subjects compared to their lean counterparts in both genders. Percentage of energy intake from fat was significantly higher in obese men compared to men with normal weight or WC. Energy percentages from carbohydrates and fibres were negatively related to BMI and WC in men, whereas in women a higher carbohydrate and fibre intake was positively associated with obesity. Alcohol intake was positively associated with WC in men. Subjects participating in health related sports reported higher intake of carbohydrates, but lower intake of fat compared to subjects not participating in sports. Conclusion This study supports the evidence that

    Objective To obtain distinct dietary patterns in the third trimester of pregnancy using principal components analysis (PCA); to determine associations with socio-demographic and lifestyle factors. Design and methods A total of 12 053 pregnant women partaking in a population-based cohort study recorded current frequency of food consumption via questionnaire in 1991-1992. Dietary patterns identified using PCA were related to social and demographic characteristics and lifestyle factors. Results Five dietary patterns were established and labelled to best describe the types of diet being consumed in pregnancy. The ‘health conscious’ component described a diet based on salad, fruit, rice, pasta, breakfast cereals, fish, eggs, pulses, fruit juices, white meat and non-white bread. The ‘traditional’ component loaded highly on all types of vegetables, red meat and poultry. The ‘processed’ component was associated with high-fat processed foods. The ‘confectionery’ component was characterized by snack foods with high sugar content and the final ‘vegetarian’ component loaded highly on meat substitutes, pulses, nuts and herbal tea and high negative loadings were seen with red meat and poultry. There were strong associations between various socio-demographic variables and all dietary components; in particular, a ‘health conscious’ diet was positively associated with increasing education and age and non-white women. There was a negative association with increased parity, single, non-working women, those who smoked and who were overweight pre-pregnancy. Opposite associations were seen with the ‘processed’ component. Conclusions Distinct dietary patterns in pregnancy have been identified. There is clear evidence of social patterning associated with the dietary patterns, these social factors need to be accounted for in future studies using dietary patterns. This study will form the basis for further work investigating pregnancy outcome. PMID:17375108

    This study aimed to identify dietary behaviors that might be considered as associated factors for overweight or obesity among French adolescents. Forty-nine of the 536 middle and high schools in Aquitaine (southwest of France) were invited to take part in the study. For each school, participating adolescents were selected using stratification by grade. A self-report questionnaire, including information about sex, age, dietary behaviors, physical and sedentary activities, and parental socioeconomic status (SES), was filled in by adolescents during class. Overweight and obesity were defined according to the age- and sex-specific body mass index cutoff points of the International Obesity Task Force. Multivariate analysis (logistic regression) was used to identify independent dietary factors associated with overweight including obesity and obesity alone (adjustment on sex, age, parental SES, and weight status and adolescents' sedentary activity). In addition to parental SES and weight status and adolescents' sedentary activity, some dietary behaviors are also independently and significantly associated with a higher prevalence of overweight including obesity: absence (OR 1.43, 0.91-2.23) or rare (OR 1.57, 1.23-2.01) breakfast intake (p < 0.01) and absence (OR 5.03, 3.19-7.92) or rare (OR 1.90, 1.46-2.47) light afternoon meal intake (p < 0.001). All variables were also significantly and independently associated with obesity alone. This study shows that socioeconomic factors and individual behaviors are associated with overweight or obesity. These results confirm the importance to carry out multifaceted educational actions among adolescents, by promoting physical activity and healthy food choices in order to prevent overweight and promote healthy lifestyle behaviors.

    Full Text Available Colon cancer rates are rising dramatically in once low incidence nations. These nations are undergoing rapid economic development and are known as “nations in transition” (NIT. This review identifies some of the most common etiological risk factors of colon cancer in these nations and evaluates the existing epidemiological evidence. The main risk factors which were found to be prevalent in NIT include: lifestyle factors such as physical inactivity, obesity and abdominal adiposity, alcohol consumption and cigarette smoking; dietary factors such as fatty food and red meat consumption. Protective factors included white meat and fiber consumption. Several studies found to have significantly higher rates of colon cancer among the young population (<40 years old. There appears to be a quantitative and qualitative increase in risk to relatives of patients diagnosed at a young age compared with those diagnosed later in life, at least part of which is likely to be the result of a hereditary susceptibility. Close relatives of patients with colon cancer are at an increased risk of developing a colon cancer. Close relatives of early onset cases warrant more intensive endoscopic screening and at an earlier age than relatives of patients diagnosed at older ages. Furthermore, these suggest the existence of genetic predispositions in these nations which need to be investigated further and have implications for screening programs. In conclusion, public health awareness campaigns promoting prevention of modifiable risk factors and screening initiatives with guidelines suited to the age-specific incidence rates of NIT are needed very urgently.

    The role of gastrointestinal infection as a factor determining vitamin B12 status in populations with low intake of animal-source foods is unclear. To determine dietary adequacy and serum concentrations of vitamin B12 in an extremely impoverished indigenous population of Panamanian children aged 12 to 60 months, and to identify predictors of both dietary and serum vitamin B12. A previous community-based survey provided the usual dietary intake and personal, household, and infection (Ascaris and diarrheal disease) information for 209 weaned children. Serum vitamin B12 was assayed using electrochemiluminescence for 65 of these children. Children with adequate or inadequate dietary vitamin B12 intake were compared, and predictors of dietary and serum vitamin B12 were identified using stepwise regression analyses of one index child per household. Dietary vitamin B12 intake was inadequate in 43% of children; these children were poorer, had less frequent diarrhea, and obtained a higher percentage of their energy from carbohydrate than children with adequate intake. Energy intake positively predicted dietary vitamin B12 intake. In contrast, serum vitamin B12 concentrations were normal in all but 3% of the children. Serum vitamin B12 was positively associated with weekly servings of fruit, corn-based food, and name (a traditional starchy food), but not with animal-source foods. Finally, serum vitamin B12 was not associated with Ascaris intensity but was lowered with increasing frequency of diarrhea. Although inadequate dietary intake of vitamin B12 was common, most serum values were normal. Nevertheless, diarrheal disease emerged as a negative predictor of serum vitamin B12 concentration.

    AIM: To examine if dietary and socio-economic factors contribute to Helicobacter pylori (H pylori) re-infection.METHODS: The population of patients consisted of subjects in whom H py/or/infection had been successfully treated in the past. Patients were divided into two groups;I-examined group (111 persons with Hpy/or/re-infection) and Ⅱ-control group (175 persons who had not been re-infected). The respondents were interviewed retrospectively on their dietary habits and socio-economic factors.RESULTS: A statistically significant lower frequency of fermented dairy products (P < 0.0001), vegetables (P = 0.02), and fruit (P = 0.008) consumption was noted among patients with H pylori re-infection as compared to those who had not been re-infected.CONCLUSION: High dietary intake of probiotic bacteria, mainly lactobacillus, and antioxidants, mainly vitamin C (contained in fruit and vegetables), might decrease the risk of Hpylori re-infection.

    Full Text Available OBJECTIVE: The impact of dietary factors on tinnitus has received limited research attention, despite being a considerable concern among people with tinnitus and clinicians. The objective was to examine the link between dietary factors and presence and severity of tinnitus. DESIGN: This study used the UK Biobank resource, a large cross-sectional study of adults aged 40-69. 171,722 eligible participants were asked questions specific to tinnitus (defined as noises such as ringing or buzzing in the head or ears. Dietary factors included portions of fruit and vegetables per day, weekly fish consumption (oily and non-oily, bread type, cups of caffeinated coffee per day, and avoidance of dairy, eggs, wheat and sugar. We controlled for lifestyle, noise exposure, hearing, personality and comorbidity factors. RESULTS: Persistent tinnitus, defined as present at least a lot of the time, was elevated with increased: (i fruit/vegetable intake (OR = 1.01 per portion/day, (ii bread (wholemeal/wholegrain, OR = 1.07; other bread, 1.20 and (iii dairy avoidance (OR = 1.27. Persistent tinnitus was reduced with: (i fish consumption (non-oily, OR = 0.91; oily, 0.95, (ii egg avoidance (OR = 0.87 and (iii caffeinated coffee consumption (OR = 0.99 per cup/day. Reports of “bothersome” tinnitus (moderate-severe handicap reduced with wholemeal/wholegrain bread intake (OR = 0.86 [corrected].Reports of less frequent transient tinnitus increased with dairy avoidance (OR = 1.18 and decreased with caffeinated coffee (OR = 0.98 per cup/day and brown bread (OR = 0.94. CONCLUSIONS: This is the first population study to report the association between dietary factors and tinnitus. Although individually dietary associations are mostly modest, particular changes in diet, such as switching between foodstuffs, may result in stronger associations. These findings offer insights into possible dietary associations with tinnitus, and this may be useful

  6. Dietary factors impact on the association between CTSS variants and obesity related traits.

    Full Text Available BACKGROUND/AIMS: Cathepsin S, a protein coded by the CTSS gene, is implicated in adipose tissue biology--this protein enhances adipose tissue development. Our hypothesis is that common variants in CTSS play a role in body weight regulation and in the development of obesity and that these effects are influenced by dietary factors--increased by high protein, glycemic index and energy diets. METHODS: Four tag SNPs (rs7511673, rs11576175, rs10888390 and rs1136774 were selected to capture all common variation in the CTSS region. Association between these four SNPs and several adiposity measurements (BMI, waist circumference, waist for given BMI and being a weight gainer-experiencing the greatest degree of unexplained annual weight gain during follow-up or not given, where applicable, both as baseline values and gain during the study period (6-8 years were tested in 11,091 European individuals (linear or logistic regression models. We also examined the interaction between the CTSS variants and dietary factors--energy density, protein content (in grams or in % of total energy intake and glycemic index--on these four adiposity phenotypes. RESULTS: We found several associations between CTSS polymorphisms and anthropometric traits including baseline BMI (rs11576175 (SNP N°2, p = 0.02, β = -0.2446, and waist change over time (rs7511673 (SNP N°1, p = 0.01, β = -0.0433 and rs10888390 (SNP N°3, p = 0.04, β = -0.0342. In interaction with the percentage of proteins contained in the diet, rs11576175 (SNP N°2 was also associated with the risk of being a weight gainer (p(interaction = 0.01, OR = 1.0526--the risk of being a weight gainer increased with the percentage of proteins contained in the diet. CONCLUSION: CTSS variants seem to be nominally associated to obesity related traits and this association may be modified by dietary protein intake.

    The role of epigenetic alterations in various human chronic diseases has gained increasing attention and has resulted in a paradigm shift in our understanding of disease susceptibility. In the field of cancer research, e.g., genetic abnormalities/mutations historically were viewed as primary underlying causes; however, epigenetic mechanisms that alter gene expression without affecting DNA sequence are now recognized as being of equal or greater importance for oncogenesis. Methylation of DNA, modification of histones, and interfering microRNA (miRNA) collectively represent a cadre of epigenetic elements dysregulated in cancer. Targeting the epigenome with compounds that modulate DNA methylation, histone marks, and miRNA profiles represents an evolving strategy for cancer chemoprevention, and these approaches are starting to show promise in human clinical trials. Essential micronutrients such as folate, vitamin B-12, selenium, and zinc as well as the dietary phytochemicals sulforaphane, tea polyphenols, curcumin, and allyl sulfur compounds are among a growing list of agents that affect epigenetic events as novel mechanisms of chemoprevention. To illustrate these concepts, the current review highlights the interactions among nutrients, epigenetics, and prostate cancer susceptibility. In particular, we focus on epigenetic dysregulation and the impact of specific nutrients and food components on DNA methylation and histone modifications that can alter gene expression and influence prostate cancer progression.

    Marcia C de Oliveira Otto

    Full Text Available Trends in food availability and metabolic risk factors in Brazil suggest a shift toward unhealthy dietary patterns and increased cardiometabolic disease risk, yet little is known about the impact of dietary and metabolic risk factors on cardiometabolic mortality in Brazil.Based on data from Global Burden of Disease (GBD Study, we used comparative risk assessment to estimate the burden of 11 dietary and 4 metabolic risk factors on mortality due to cardiovascular diseases and diabetes in Brazil in 2010. Information on national diets and metabolic risks were obtained from the Brazilian Household Budget Survey, the Food and Agriculture Organization database, and large observational studies including Brazilian adults. Relative risks for each risk factor were obtained from meta-analyses of randomized trials or prospective cohort studies; and disease-specific mortality from the GBD 2010 database. We quantified uncertainty using probabilistic simulation analyses, incorporating uncertainty in dietary and metabolic data and relative risks by age and sex. Robustness of findings was evaluated by sensitivity to varying feasible optimal levels of each risk factor.In 2010, high systolic blood pressure (SBP and suboptimal diet were the largest contributors to cardiometabolic deaths in Brazil, responsible for 214,263 deaths (95% uncertainty interval [UI]: 195,073 to 233,936 and 202,949 deaths (95% UI: 194,322 to 211,747, respectively. Among individual dietary factors, low intakes of fruits and whole grains and high intakes of sodium were the largest contributors to cardiometabolic deaths. For premature cardiometabolic deaths (before age 70 years, representing 40% of cardiometabolic deaths, the leading risk factors were suboptimal diet (104,169 deaths; 95% UI: 99,964 to 108,002, high SBP (98,923 deaths; 95%UI: 92,912 to 104,609 and high body-mass index (BMI (42,643 deaths; 95%UI: 40,161 to 45,111.suboptimal diet, high SBP, and high BMI are major causes of

    1. To investigate the growth performance and histological intestinal alterations of Aigamo ducks fed on dietary combinations of zeolite, plant extract and vermiculite (ZEM, 14-d-old Aigamo ducks were divided into 4 groups, with 3 replicates of 3 male and 3 female ducks. They were fed ad libitum on a basal commercial duck mash diet with 0, 0.1, 0.5 and 1.0 g/kg dietary ZEM for 63 d. 2. Body weight gain tended to be higher for the 0.1 and 0.5 g/kg ZEM groups than for the control group at 9 weeks. 3. In light microscopic observation, most values of the intestinal villus height, villus area, cell area and cell mitosis numbers were higher in the ZEM group than those of the control in all intestinal segments, and the duodenal villus height, cell area and cell mitosis of the 0.5 g/kg ZEM group, as well as jejunal cell mitosis in the 0.1 g/kg ZEM group, increased (P < 0.05). In the scanning electron microscope results, all ZEM groups showed protuberant epithelial cells and cell clusters on the villus apical surface of the duodenum and ileum. In the jejunum, villus gyri were frequently observed in the 0.1 g/kg ZEM group. These histological intestinal alterations suggest that intestinal villi and epithelial cellular functions might have been activated. 4. From the present results, dietary ZEM showed hypertrophied functions of intestinal villi and epithelial cells at the duodenum and ileum, and the 0.1 and 0.5 g/kg levels improved body weight gain. These suggest that the ZEM can be supplemented until a level of 1.0 g/kg.

Pharmacological therapy is in accordance with the severity of pain and may include acute, prophylactic and most commonly both approaches. The aim of the acute therapy is stopping or alleviating the attack or progression of the pain and in case of a migraine attack that has started, lessening the pain it. Preventive therapy aims to reduce attack frequency and severity. This study was designed to evaluate the effect of dietary factors in the management and prophylaxis of migraine in cases diagnosed as having migraine disorder according to the 2003-IHS criteria. Fifty consecutive Turkish patients (13 men, 37 women with diagnosis of migraine were randomly divided into two groups for treatment protocols with the written approval of the ethics committee. The cases in the first group (K were treated with metoprolol, vitamin B2 (riboflavin, and naproxen sodium just at the aura or at the beginning of the attacks. The cases in the second group (D were also supplied with a comprehensive dietary list arranged by our algology clinics in addition to the same medication protocol. There were no demographic differences between the cases (P > 0.05. VAS scores were lower in group D than group K (P < 0.01, and also the migraine attack frequencies and monthly amounts of analgesic consumed amounts were also statistically significantly less. It was concluded that beta-blocker and riboflavin therapy supplemented with convenient diet with appropriate alternatives in patients with migraine disorder was associated with statistically significant decreases in headache frequency, intensity, duration and medication intake.Keywords: migraine, food intake, trigger

    Apps using digital photos to track dietary intake and provide feedback are common, but currently there has been no research examining what evidence-based strategies are included in these apps. A content analysis of mobile apps for photo diet tracking was conducted, including whether effective techniques for interventions promoting behavior change, including self-regulation, for healthy eating (HE) are targeted. An initial search of app stores yielded 34 apps (n = 8 Android and Apple; n = 11 Android; n = 15 Apple). One app was removed (unable to download), and other apps (n = 4) were unable to be rated (no longer available). Remaining apps (n = 29) were downloaded, reviewed, and coded by 2 independent reviewers to determine the number of known effective self-regulation and other behavior change techniques included. The raters met to compare their coding of the apps, calculate interrater agreement, resolve any discrepancies, and come to a consensus. Six apps (21%) did not utilize any of the behavior change techniques examined. Three apps (10%) provided feedback to users via crowdsourcing or collective feedback from other users and professionals, 7 apps (24%) used crowdsourcing or collective feedback, 1 app (3%) used professionals, and 18 apps (62%) did not provide any dietary feedback to users. Few photo diet-tracking apps include evidence-based strategies to improve dietary intake. Use of photos to self-monitor dietary intake and receive feedback has the potential to reduce user burden for self-monitoring, yet photo diet tracking apps need to incorporate known effective behavior strategies for HE, including self-regulation. © 2016 Diabetes Technology Society.

    Human and animal studies demonstrate an untoward effect of excess dietary NaCl (salt) intake on cardiovascular function and life span. The endothelium in particular augments the production of transforming growth factor (TGF)-beta, a fibrogenic growth factor, in response to excess dietary salt intake. This study explored the initiating mechanism that regulates salt-induced endothelial cell production of TGF-beta. Male Sprague-Dawley rats were given diets containing different amounts of NaCl and potassium for 4 days. A bioassay for TGF-beta demonstrated increased (35.2%) amounts of active TGF-beta in the medium of aortic ring segments from rats on the high-salt diet compared with rats maintained on a 0.3% NaCl diet. Inhibition of the large-conductance, calcium-activated potassium channel inhibited dietary salt-induced vascular production of TGF-beta but did not affect production of TGF-beta by ring segments from rats on the low-salt diet. Immunohistochemical and Western analyses demonstrated the alpha subunit of the calcium-activated potassium channel in endothelial cells. Increasing medium [K+] inhibited production of dietary salt-induced vascular production levels of total and active TGF-beta but did not alter TGF-beta production by aortic rings from rats on the 0.3% NaCl diet. Increasing dietary potassium content decreased urinary active TGF-beta in animals receiving the high-salt diet but did not change urinary active TGF-beta in animals receiving the low-salt diet. The findings demonstrated an interesting interaction between the dietary intake of potassium and excess NaCl and further showed the fundamental role of the endothelial calcium-activated potassium channel in the vascular response to excess salt intake.

    In the most recent risk assessment for Bisphenol A for the first time a multi-route aggregate exposure assessment was conducted by the European Food Safety Authority. This assessment includes exposure via dietary sources, and also contributions of the most important non-dietary sources. Both average and high aggregate exposure were calculated by source-to-dose modeling (forward calculation) for different age groups and compared with estimates based on urinary biomonitoring data (backward calculation). The aggregate exposure estimates obtained by forward and backward modeling are in the same order of magnitude, with forward modeling yielding higher estimates associated with larger uncertainty. Yet, only forward modeling can indicate the relative contribution of different sources. Dietary exposure, especially via canned food, appears to be the most important exposure source and, based on the central aggregate exposure estimates, contributes around 90% to internal exposure to total (conjugated plus unconjugated) BPA. Dermal exposure via thermal paper and to a lesser extent via cosmetic products may contribute around 10% for some age groups. The uncertainty around these estimates is considerable, but since after dermal absorption a first-pass metabolism of BPA by conjugation is lacking, dermal sources may be of equal or even higher toxicological relevance than dietary sources.

    Low-sodium Dietary Approaches to Stop Hypertension (DASH) diets are base producing but restrict red meat without clear justification. We hypothesized that a vitality diet (VD), a low-sodium DASH-type diet with a low dietary acid load containing 6 servings of 100 g cooked lean red meat per week, would be more effective in reducing blood pressure (BP) compared with a higher acid load reference healthy diet (RHD) based on general dietary guidelines to reduce fat intake and increase intake of breads and cereals. A randomized, parallel dietary intervention study was conducted to compare the BP-lowering effect of these 2 diets in postmenopausal women with high/normal BP. Women were randomly assigned to follow either VD or RHD for 14 weeks. Home BP was measured daily with an automated BP monitor under standard conditions. Of 111 women commencing the study, 95 completed (46 VD, 49 RHD). Systolic BP (SBP) throughout the intervention was lower in the VD group compared to the RHD group (repeated-measures analysis of variance time by diet, P = .04), such that at the end of the study, the VD had a fall of SBP by 5.6 +/- 1.3 mm Hg (mean +/- SEM) compared with a fall of 2.7 +/- 1.0 mm Hg in the RHD (group difference, P = .08). When only those taking antihypertensive medications were assessed, the VD (n = 17) had a significant fall of 6.5 +/- 2.5 mm Hg SBP (P = .02) and 4.6 +/- 1.4 mm Hg diastolic BP (P = .005) after 14 weeks, and their BP was lower than that of the RHD group (n = 18) throughout the study (P dietary acid load, which also included lean red meat on most days of the week, was effective in reducing BP in older women, particularly in those taking antihypertensive medications.

    Full Text Available Background: Scientific workers play an important role in the development of science and technology. However, evidence is lacking with regard to the associations between their dietary factors and their health-related quality of life (HRQOL. Methods: A cross-sectional survey was conducted among 775 scientific workers from multiple universities and institutes in the Southwest region of China. A self-administered food-frequency questionnaire was used to collect the food consumption information, and the 36-item Short-Form Health Survey was used to assess physical HRQOL. Hierarchical multiple regression analysis was used to identify the factors associated with scientific workers’ HRQOL. Results: Physical HRQOL was negatively associated with age and intake of fresh pork (fat and animal viscera, whereas consumption of vegetables, fruits, refined cereals and dairy products were positively correlated with physical HRQOL. Participants with daily intake of vegetable oils or mixed oils showed higher physical HRQOL scores than those with intake of animal oils. Conclusions: Dietary habits are closely associated with the physical HRQOL of scientific workers. The dietary patterns that had more vegetables and fruits, less fresh pork (fat and animal viscera, and used vegetable oils during cooking corresponded to higher physical HRQOL scores. These findings are important for planning dietary strategies to improve physical health in scientific workers.

    Only few studies examined the effect of diet on prospective changes in cardiometabolic (CM) risk factors in children and youth despite its importance for understanding the role of diet early in life for cardiovascular disease in adulthood. To test the hypothesis that dietary intake is associated with prospective changes in CM risk factors, we analyzed longitudinal observations made over a period of 2 years among 448 students (aged 10-17 years) from 14 schools in Canada. We applied mixed effect regression to examine the associations of dietary intake at baseline with changes in body mass index, waist circumference (WC), systolic and diastolic blood pressure (SBP and DBP), and insulin sensitivity score between baseline and follow-up while adjusting for age, sex, and physical activity. Dietary fat at baseline was associated with increases in SBP and DBP z scores (per 10 g increase in dietary fat per day: β = 0.03; p hypertension in children and youth, and their cardiometabolic sequelae later in life.

    Dietary antioxidants may be useful in counteracting the chronic inflammatory status in neurodegenerative diseases by reducing oxidative stress due to accumulation of reactive oxygen species (ROS). In this study, we newly described the efficacy of a number of dietary antioxidants (polyphenols, carotenoids, thiolic compounds, and oligoelements) on viability of neuronal PC12 cells following Nerve Growth Factor (NGF) deprivation, a model of age-related decrease of neurotrophic support that triggers neuronal loss. Neuroprotection by antioxidants during NGF deprivation for 24 h was largely dependent on their concentrations: all dietary antioxidants were able to efficiently support cell viability by reducing ROS levels and restoring mitochondrial function, while preserving the neuronal morphology. Moreover, ROS reduction and neuroprotection during NGF withdrawal were also achieved with defined cocktails of 3-6 different antioxidants at concentrations 5-60 times lower than those used in single treatments, suggesting that their antioxidant activity was preserved also at very low concentrations. Overall, these data indicate the beneficial effects of antioxidants against oxidative stress induced by decreased NGF availability and suggest that defined cocktails of dietary factors at low concentrations might be a suitable strategy to reduce oxidative damage in neurodegenerative diseases, while limiting possible side effects.

    This cross-sectional, population-based study aimed to estimate the prevalence of dietary mineral inadequacies among residents in urban areas of Sao Paulo, to identify foods contributing to mineral intake and to verify possible associations between socio-demographic and lifestyle factors and mineral intake. Data were obtained from the 2008 Health Survey of Sao Paulo (n 1511; mean age 43·6 (sd 23·2), range 14-97 years). Dietary intake of minerals was measured using two 24-h dietary recalls. Socio-demographic and lifestyle data were collected. The prevalence of inadequate intake was estimated according to Dietary Reference Intakes methods. Associations between mineral intake and baseline factors were determined using multiple linear regression. Na, Ca and Mg showed the highest dietary inadequacies. Some age/sex groups had lower intakes of P, Zn, Cu and Se. Rice, beans and bread were the main foods contributing towards mineral intake. Female sex was negatively associated with K, Na, P, Mg, Zn and Mn intakes. All age groups were positively associated with the intakes of K, P, Mg and Mn. Family income above one minimum wage was positively associated with Se intake. Living in a household whose head completed ≥10 years of education was positively associated with Ca and negatively associated with Na intake. Former smoker status was negatively associated with Ca intake. Current smoker status was inversely associated with K, Ca, P and Cu intakes. Sufficient physical activity was positively associated with K, Ca and Mg intakes. Overall, the intakes of all major minerals were inadequate and were influenced by socio-demographic and lifestyle factors.

    To determine the factors that are commonly associated with both the dietary habits of older adults living in the community and depressive symptoms in this group. Secondary analysis of data on Mexico City obtained by means of the multicenter study on Health, Well-being, and Aging (Salud, Bienestar y Envejecimiento, SABE) that was carried out in 1999 and 2000. The following variables were examined: presence or absence of depressive symptoms, according to Yesavage's Geriatric Depression Scale (GDS); mental status, as reflected by the score obtained on a modified, shortened version of Folstein's Mini-mental State Examination (MMSE); and functional capacity, as measured by Katz' Index of Independence in Activities of Daily Living. Those whose score on the shortened MMSE was 12 points or less were asked to respond to the Pfeffer Functional Activities Questionnaire, which was used to assess their ability to perform the basic activities of daily living. Information was obtained through self-report on the material, physical, psychological, and social aspects of purchasing, preparing, and consuming food products and of oral health status during the most recent 12-month period. Variables that were significantly associated with the results obtained on the GDS were included in a multivariate regression analysis; several statistical models were created, and variables that were shown to be statistically significant in the stepwise multivariate linear regression were used to determine the best-fitting explanatory model for the results obtained on the GDS. The average age of study participants was 64.4 +/- 8.6 years, and the prevalence of depressive symptoms was 66%. The score obtained on the GDS showed a significant association with the presence of arterial hypertension (P < 0.01), but not with the self-reported presence of diabetes, neoplasia, stroke, lung disease or heart disease. However, the use of dental prostheses (P < 0.01), urinary incontinence (P < 0.01), and falls (P < 0

    In this study, we investigated the hypothesis that dietary protein content and type are related to cardiometabolic risk factors including body mass index, waist circumference (WC), serum triglycerides, high-density lipoprotein cholesterol (HDL-C), serum fasting glucose, and blood pressure. This population-based study was conducted on 2537 subjects aged 19 to 70 years and selected from among participants of the Tehran Lipid and Glucose Study (2006-2008). Dietary data were collected using a validated semiquantitative food frequency questionnaire. Associations between intakes of total protein as well as the animal-to-plant (A/P) protein ratio and cardiometabolic risk factors were analyzed using multivariate linear regression models. Dietary protein intakes were 13.7% and 13.6% of energy, in men and women, respectively; the A/P protein ratio in women was significantly higher than in men (1.8 ± 1.4 vs 1.4 ± 0.9). Body mass index was associated with total protein intake in men (β = 0.14, P = .01) and A/P protein ratio in women (β = 0.075, P = .01). Waist circumference was associated with total protein intake (β = -0.048, P = .03) and A/P protein ratio (β=0.031, P = .05) in women. Serum fasting glucose was associated with both total protein intake (β=0.061 and 0.11, P protein intake (β = 0.107 and 0.07, P protein intake (β = -0.125, P = .01). In conclusion, higher dietary protein intake was associated with enhanced HDL-C levels, WC, and diastolic BP, and a higher ratio of A/P protein intake was related with lower serum fasting glucose andWC.

  18. Dietary phosphorus excess: a risk factor in chronic bone, kidney, and cardiovascular disease?

    2013-09-01

    There is growing evidence in the nephrology literature supporting the deleterious health effect of excess dietary phosphorus intake. This issue has largely escaped the attention of nutrition experts until this symposium, which raised the question of whether the same health concerns should be extended to the general population. The potential hazard of a high phosphorus intake in the healthy population is illustrated by findings from acute and epidemiologic studies. Acute studies in healthy young adults demonstrate that phosphorus intakes in excess of nutrient needs may significantly disrupt the hormonal regulation of phosphorus contributing to disordered mineral metabolism, vascular calcification, bone loss, and impaired kidney function. One of the hormonal factors acutely affected by dietary phosphorus loading is fibroblast growth factor-23, which may be a key factor responsible for many of the cardiovascular disease (CVD) complications of high phosphorus intake. Increasingly, large epidemiological studies suggest that mild elevations of serum phosphorus within the normal range are associated with CVD risk in healthy populations. Few population studies link high dietary phosphorus intake to mild changes in serum phosphorus due to study design issues specific to phosphorus and inaccurate nutrient composition databases. The increasing phosphorus intake due to the use of phosphorus-containing ingredients in processed food and the growing consumption of processed convenience and fast foods is an important factor that needs to be emphasized.

    It is well known that cardiovascular disease is the leading cause of mortality in the western societies. A number of risk factors such as family history, diabetes, hypertension, obesity, diabetes, smoking and physical inactivity are responsible for a significant proportion of the overall cardiovascular risk. Interestingly, recent data suggest there is a gradient in the incidence, morbidity and mortality of cardiovascular disease across the spectrum of socioeconomic status, as this is defined by educational level, occupation or income. Additionally, dietary mediators seem to play significant role in the pathogenesis of cardiovascular disease, mediating some of the discrepancies in atherosclerosis among different socioeconomic layers. Therefore, in the present article, we aim to review the association between socioeconomic status and cardiovascular disease risk factors and the role of different dietary mediators.

Interviews were conducted with a random sample of 134 Amish and 154 non-Amish adults including questions about dietary practices and a 24-h dietary recall. Amish compared to non-Amish adults reported (1) less refrigeration in homes (85% vs. 100%, P food from restaurants and grocery stores (P cancer although neither group achieves current diet and cancer prevention guidelines. Lifestyle factors, screening, and healthcare access may be contributing to the lower cancer incidence rates among the Amish and these results suggest areas of intervention to reduce the cancer burden.

    To investigate the dietary pattern in college freshmen students and to analyze the influencing factors on their dietary patterns. A questionnaire survey on situation of dietary pattern and influencing factors was conducted among 1319 freshmen students. Four major dietary patterns were noticed and they were: I, high consumption in hamburger, fried food, nuts, biscuit, chocolate, cola, coffee, sugars, II, high consumption in pork, mutton, beef, poultry meat, animal liver, III, high consumption in fresh fruits, eggs, fish and shrimps, kelp laver and sea fish, milk and dairy products, beans and bean products, IV, high consumption in rice and grain, fresh fruits, fresh vegetables, pork. Risk factors on dietary pattern were presented as follows: (1) boys:having the food pattern I and II showed a strong positive association with the place where they live (OR = 1.67, 95%CI: 0.87 - 3.19; OR = 1.51, 95%CI: 0.79 - 2.88), eating place (OR = 1.63, 95%CI: 1.03 - 2.59;OR = 1.83, 95%CI: 1.04 - 3.23), level of mother's education (OR = 2.52, 95%CI: 1.07 - 5.95; OR = 3.38, 95%CI: 1.50 - 7.63), family income (OR = 2.24, 95%CI: 1.30 - 3.88; OR = 3.06, 95%CI: 1.77 - 5.29) and the status of passive smoking (OR = 1.80, 95%CI: 0.70 - 4.59; OR = 1.83, 95%CI: 0.75 - 4.45). Inverse correlations was found on the level of mother's education (OR = 0.56, 95%CI: 0.17 - 1.79). The food pattern IV showed a strong positive association with place of eating (OR = 1.83, 95%CI: 1.04 - 3.23) but having an inverse correlation with the level of mother's education (OR = 0.56, 95%CI: 0.17 - 1.79). (2) girls when compared with boys, the food pattern I showed minor association with the places of living and eating; while the food pattern II and III had minor association with the status of passive smoking. Socio-demographic factors and lifestyle had influenced on the dietary patterns among college freshmen students who should be guided to have a reasonable, balanced diet in the college.

    Full Text Available Background. This study analysed the correlation between characteristic dietary and non-dietary factors of fracture risk in women and mineral density of bone tissue (BMD. Material and methods. The study involved examination of 172 women, aged between 32 and 59. Calcium intake from a daily diet was determined with the use of the semi-quantitative food consumption frequency method. The physical activity of the women was expressed in MET-minutes/week. BMD was determined by double-energy X-ray absorptiometry (DXA. The frequency of bone fracture and osteoporosis risk factors was determined and a 10-year risk of fracture (RB-10 was individually diagnosed according to the WHO and IOF criteria (2007. A high level of fracture risk (RB-10 > 14% was assumed according to the Johnell’s algorithm [2005]. Results. The most frequent factors of fracture risk in women included: bone pains (76% of the total sample, inadequate calcium intake (43%, smoking (24%, previous fractures (24%, incidence of chronic diseases (22%, menstrual disorders (19%, family history of osteoporosis (17%, low physical activity (15% and the incidence of thyroid disorders (10%. 85% of women had at least one factor of 10-year absolute risk of fracture. None of the examined women consumed a sufficient amount of calcium and the average calcium intake level was low (median of about 400 mg/day. Bone mineral density did not reveal any relationship with current intake of calcium by women, but depended on the consumption of dairy products in the past. Conclusions. Daily consumption of dairy products in childhood and in the school period was conductive to a higher mineral density of bone tissue in women. Advanced age and the occurrence of menstrual disorders were conductive to a lower mineral density of bone tissue in women. Women with low bone mineral density (lower BMD tertile more frequently used supplementation with preparations containing calcium (25% and more often had at least one RB

    Diet and physical activity (PA) are essential components of nutritional status. Adequate nutrition and an active lifestyle are key factors during childhood, because food habits track into adulthood. Children spend more time in school than in any other environment away from home. Studying the diet factors and patterns of PA that affect obesity risk in children during school hours and the complete school day can help identify opportunities to lower this risk. We directly measured the time children spent performing moderate to vigorous PA (MVPA) at school, compared the amount and intensity of PA during school hours with after-school hours, and tried to determine if diet behaviors and PA or inactivity were associated with excess weight and body fat. This cross-sectional study included 143 normal-weight (NLW) and 48 obese children aged 8-10 y. Diet data were obtained from two 24-h recalls. Body composition was measured by bioimpedance. Screen time and sports participation data were self-reported. NLW children drank/ate more dairy servings than the obese children, who consumed more fruit-flavored water than the NLW group. Consumption of soft drinks, sugar-added juices, and fresh juices was low in both groups. Children were less active during school hours than after school. MVPA was lower during school hours in the obese group than in the NLW group. Schools, parents, and authorities should be more involved in promoting strategies to improve the dietary habits and PA levels of school-aged children, because this group is not achieving the recommended level of daily MVPA.

    Aminotransferase activity is a surrogate marker of liver injury showing strong correlations with obesity and metabolic syndrome. However, elevated aminotransferase activity is not uncommon in non-obese and non-alcoholic patients in clinical practice. To examine the relationship between sarcopenia and aminotransferase activity in a large population-based cohort. Data from the Korean National Health and Nutrition Examinations were used. A total of 13,431 subjects were included. A whole-body dual X-ray absorptiometry scan was performed on each patient to measure total and regional muscle mass. Appendicular skeletal muscle mass indices were also obtained. The prevalence of sarcopenia was significantly higher in the group with elevated aminotransferase levels than in the normal liver enzyme group (males: 26.5% vs. 16.9%; females: 38.3% vs. 22.1%, pfasting glucose and cholesterol levels. The frequency of elevated aminotransferase increased in male patients with sarcopenia after adjusting for potential confounding factors including age, body mass index, fasting glucose level, dietary, and exercise habits. However, the correlation was no longer observed in women after adjusting for body mass index. Sarcopenia is a risk factor for elevated aminotransferase in men, independently of body mass index, dietary habits, and physical activity. Copyright © 2015 Editrice Gastroenterologica Italiana S.r.l.

    Full Text Available This review aims to search and summarise the available evidence on the association between dietary factors and type 2 diabetes mellitus (T2DM in Middle Eastern populations, where diabetes prevalence is among the highest in the world. Electronic databases were searched; authors, libraries, and research centres in the Middle East were contacted for further studies and unpublished literature. Included studies assessed potential dietary factors for T2DM in Middle Eastern adults. Two reviewers assessed studies independently. Extensive searching yielded 17 studies which met the inclusion criteria for this review. The findings showed that whole-grain intake reduces the risk of T2DM, and potato consumption was positively correlated with T2DM. Vegetables and vegetable oil may play a protective role against T2DM. Dietary patterns that are associated with diabetes were identified, such as Fast Food and Refined Grains patterns. Two studies demonstrated that lifestyle interventions decreased the risk of T2DM. In summary, the identified studies support an association between some dietary factors and T2DM; however, many of the included studies were of poor methodological quality so the findings should be interpreted with caution. The review draws attention to major gaps in current evidence and the need for well-designed studies in this area.

    A case-control study was designed to investigate association of dietary factors with the risk of lung cancer in Sichuan,China.The cases consisted of 135 patients with preinvasive lung cancer which had been confirmed with histopathology,fiber bronchoscope,CT and X-ray film in three provincial hospitals in the recent one year.Controls were healthy subjects who went to one of these hospitals for health check-up;patients with pulmonary diseases was exluded.Controls were matched to cases for sex and age with a ratio of 1:1.Nutrient intakes, the eating habit and other relevant factors were investigated.The data analyzed with the conditional logistic regression model indicated,that dietary beta-carotene intakes had a significantly inverse association with the risk of lung cancer.Vitamin Chad a less significantly inverse association with the risk.Association of protein,fat,energy,retinol intakes of dietbalance index with the risk was not significant.Association of tea,alcohol,garlic or mushroom,respectively,with the risk was also not observed.Consumption of more processed foods and deep-fried foods were found to be risk factors.Smoking and air pollution from coal burning stoves were also observed as independent risk factors of lung cancer in the present study.The mental stress incidence in the case was significantly higher than that in the control.

  20. High Dietary Fructose: Direct or Indirect Dangerous Factors Disturbing Tissue and Organ Functions

    Directory of Open Access Journals (Sweden)

    Dong-Mei Zhang

    2017-03-01

    Full Text Available High dietary fructose is a major contributor to insulin resistance and metabolic syndrome, disturbing tissue and organ functions. Fructose is mainly absorbed into systemic circulation by glucose transporter 2 (GLUT2 and GLUT5, and metabolized in liver to produce glucose, lactate, triglyceride (TG, free fatty acid (FFA, uric acid (UA and methylglyoxal (MG. Its extrahepatic absorption and metabolism also take place. High levels of these metabolites are the direct dangerous factors. During fructose metabolism, ATP depletion occurs and induces oxidative stress and inflammatory response, disturbing functions of local tissues and organs to overproduce inflammatory cytokine, adiponectin, leptin and endotoxin, which act as indirect dangerous factors. Fructose and its metabolites directly and/or indirectly cause oxidative stress, chronic inflammation, endothelial dysfunction, autophagy and increased intestinal permeability, and then further aggravate the metabolic syndrome with tissue and organ dysfunctions. Therefore, this review addresses fructose-induced metabolic syndrome, and the disturbance effects of direct and/or indirect dangerous factors on the functions of liver, adipose, pancreas islet, skeletal muscle, kidney, heart, brain and small intestine. It is important to find the potential correlations between direct and/or indirect risk factors and healthy problems under excess dietary fructose consumption.

    2010-12-01

    Incidence rates for oesophageal adenocarcinoma have increased by over 500% during the past few decades without clear reasons. Gastro-oesophageal reflux disease, obesity and smoking have been identified as risk factors, although the demographic distribution of these risk factors is not consistent with the demographic distribution of oesophageal adenocarcinoma, which is substantially more common among whites and males than any other demographic groups. Numerous epidemiological studies have suggested associations between dietary factors and the risks of oesophageal adenocarcinoma and its precursor, Barrett's oesophagus, though a comprehensive review is lacking. The main aim of the present review is to consider the evidence linking dietary factors with the risks of oesophageal adenocarcinoma, Barrett's oesophagus, and the progression from Barrett's oesophagus to oesophageal adenocarcinoma. The existing epidemiological evidence is strongest for an inverse relationship between intake of vitamin C, β-carotene, fruits and vegetables, particularly raw fruits and vegetables and dark green, leafy and cruciferous vegetables, carbohydrates, fibre and Fe and the risk of oesophageal adenocarcinoma and Barrett's oesophagus. Patients at higher risk for Barrett's oesophagus and oesophageal adenocarcinoma may benefit from increasing their consumption of fruits and vegetables and reducing their intake of red meat and other processed food items. Further research is needed to evaluate the relationship between diet and the progression of Barrett's oesophagus to oesophageal adenocarcinoma. Evidence from cohort studies will help determine whether randomised chemoprevention trials are warranted for the primary prevention of Barrett's oesophagus or its progression to cancer.

    Full Text Available Exploration of dietary pattern associations within a multi-ethnic society context has been limited. We aimed to describe dietary patterns of 5664 pregnant women from the Growing Up in New Zealand study, and investigate associations between these patterns and maternal socio-demographic, place of birth, health and lifestyle factors. Participants completed a food frequency questionnaire prior to the birth of their child. Principal components analysis was used to extract dietary patterns and multivariable analyses used to determine associations. Four dietary components were extracted. Higher scores on, ‘Junk’ and ‘Traditional/White bread’, were associated with decreasing age, lower educational levels, being of Pacific or Māori ethnicity and smoking. Higher scores on, ‘Health conscious’ and ‘Fusion/Protein’, were associated with increasing age, better self-rated health, lower pre-pregnancy body mass index (BMI and not smoking. Higher scores on ‘Junk’ and ‘Health conscious’ were associated with being born in New Zealand (NZ, whereas higher scores on ‘Fusion/Protein’ was associated with being born outside NZ and being of non-European ethnicity, particularly Asian. High scores on the ‘Health conscious’ dietary pattern showed the highest odds of adherence to the pregnancy dietary guidelines. In this cohort of pregnant women different dietary patterns were associated with migration, ethnicity, socio-demographic characteristics, health behaviors and adherence to dietary guidelines.

    Both dietary fat and dietary sucrose are major components of Western diets that may differentially affect the risk for body mass gain, diabetes mellitus, and cardiovascular disease. We have phenotypically analyzed mice with ubiquitously impaired expression of mitochondrial frataxin protein that were challenged with diets differing in macronutrient content, namely high-sucrose/low-fat and high-saturated fat/low-sugar diets. We find here that a high-sucrose/low-fat diet has especially detrimental effects in mice with impaired mitochondrial metabolism promoting several independent cardiovascular risk factors, including impaired glucose metabolism, fasting hyperinsulinemia, reduced glucose-stimulated insulin secretion, increased serum triglycerides, and elevated cholesterol levels due to increased expression of HMG-CoA reductase. In contrast, a high-saturated fat/low-sugar diet protects mice with impaired mitochondrial metabolism from diet-induced obesity by increasing total energy expenditure and increasing expression of ACAA2, a rate-limiting enzyme of mitochondrial beta-oxidation, whereas no concomitant improvement of glucose metabolism was observed. Taken together, our results suggest that mitochondrial dysfunction may cause sucrose to become a multifunctional cardiovascular risk factor, whereas low-sugar diets high in saturated fat may prevent weight gain without improving glucose metabolism.

    This study was conducted to elucidate the correlation among dietary intake, dietary preferences, and social-psychological factors in the youth and to examine the factors that affect such dietary behaviors as snacking, skipping breakfast, and taking a biased nutrition. A survey was carried out using a questionnaire with closed questions on multiple items such as dietary behaviors, psychosocial stress, dietary externalization, information and consciousness about health. The survey was conducted on 1,056 high school students and 1,323 university students in Japan. As a result of the factor analysis among the groups of male/female and high school/university students, relationships were found between the items of "preferences for snacking" and "snack food intakes" among all these groups. Those who like sweets and snacks tended to snack between lunch and dinner or after dinner by themselves more often than those who do not. In contrast to men, intermediate correlations were found between the item of "a meal as a diversion" and each of the items of "snack food intake," "preferences for fried foods/sautéed foods/meat dishes," and "preferences for snacking," among women who do not live alone, regardless of their being high school or university students. The item of "stress over human relationships/academic performance" was shown to have similarly weak correlations with the items of "reasons for skipping breakfast" and "nutrition intake" in the groups of male and female high school students. The less they value nutrition intake, the more they tend to be conscious of stress over human relationships/academic performance.

    Besides their possible effects on the development of inflammatory bowel disease (IBD),some environmental factors can modulate the clinical course of both ulcerative colitis (UC) and Crohn's disease (CD).This review is mainly devoted to describing the current knowledge of the impact of some of these factors on the outcome of IBD,with special emphasis on smoking and diet.Although the impact of smoking on the susceptibility to develop CD and UC is firmly established,its influence on the clinical course of both diseases is still debatable.In CD,active smoking is a risk factor for postoperative recurrence.Beyond this clinical setting,smoking cessation seems to be advantageous in those CD patients who were smokers at disease diagnosis,while smoking resumption may be of benefit in ex-smokers with resistant UC.The role of dietary habits on the development of IBD is far from being well established.Also,food intolerances are very frequent,but usually inconsistent among IBD patients,and therefore no general dietary recommendations can be made in these patients.In general,IBD patients should eat a diet as varied as possible.Regarding the possible therapeutic role of some dietary components in IBD,lessons should be drawn from the investigation of the primary therapeutic effect of enteral nutrition in CD.Low-fat diets seem to be particularly useful.Also,some lipid sources,such as olive oil,medium-chain triglycerides,and perhaps omega-3 fatty acids,might have a therapeutic effect.Fermentable fiber may have a role in preventing relapses in inactive UC.

    Full Text Available Nutritional genomics has exploded in the last decade, yielding insights—both nutrigenomic and nutrigenetic—into the physiology of dietary interactions and our genes. Among these are insights into the regulation of magnesium transport and homeostasis and mechanisms underlying magnesium’s role in insulin and glucose handling. Recent observational evidence has attempted to examine some promising research avenues on interaction between genetics and dietary magnesium in relation to diabetes and diabetes risk factors. This brief review summarizes the recent evidence on dietary magnesium’s role in diabetes and related traits in the presence of underlying genetic risk, and discusses future potential research directions.

    2015-12-01

    Full Text Available Background: The identification of major dietary patterns using factor analysis can provide information about health status of children by obtaining an overall picture of the person's diet. The aim of this study was to determine major dietary patterns and to identify socioeconomic factors affecting them in school age children in rural areas of Bijar, Iran. Materials and Methods: In this cross sectional study, 255 rural school age children living rural areas of Bijar were selected by simple random sampling. Dietary intakes during the past year and assessment of socioeconomic information were examined. Dietary patterns were determined using factor analysis and their relation to socioeconomic factors was investigated. Results: Three major dietary patterns," traditional", "modern" and "mixed", were identified. After adjusting for age, sex, ethnic and energy intake, Age of mother (b= 0.03, CI=0.00_0.05 was positively associated and age of father (b= -0.03, CI=-0.05_-0.01, laboring Job for father (b= -0.24, CI=-0.44_-0.03 and higher education of parents (b= -0.20, CI=-0.35_-0.05 were negatively associated with traditional dietary pattern. In addition, higher education of parents (b= 0.27, CI=0.11_0.44 was positively associated and age of mother (b= -0.03, CI=-0.06_0.00 was negatively associated with mixed dietary pattern. Conclusion: Some socio-economic variables such as maternal age, parental education, parental occupation and economic conditions can have effect on major dietary patterns among rural children.

    There is increasing evidence to support the relationship between acne vulgaris and diet. The aim of this study was to investigate possible associations among dietary glycemic index, glycemic load, milk consumption, insulin resistance, and adiponectin levels in the pathogenesis of acne vulgaris. The dietary glycemic index, glycemic load, milk consumption, fasting glucose, insulin, insulin-like growth factor)-1, insulin-like growth factor binding protein-3, adiponectin, and homeostasis model assessment of insulin resistance values of 50 patients with acne vulgaris and 36 healthy control subjects were measured. Glycemic index and glycemic load levels were significantly higher (P = .022 and P = .001, respectively) and serum adiponectin levels were significantly lower (P = .015) in patients with acne than in the control subjects. There was an inverse correlation between serum adiponectin concentration and glycemic index (P = .049, r = -0.212). This study used a cross-sectional design and the study population was limited to young, nonobese adults. A high-glycemic-index/-load diet was positively associated with acne vulgaris. Adiponectin may be a pathogenetic cofactor contributing to the development of the disease. Further research on adiponectin levels in patients with acne in terms of development of insulin resistance might be important in this possible relationship.

    2012-02-01

    Overweight/obesity is an epidemic in the US as well as in other developed countries, affecting two-thirds of Americans and an estimated 2.3 billion people worldwide. Obesity increases the risk for Type 2 diabetes, cardiovascular disease and cancer. For example, epidemiological studies have established a strong association between obesity and colon cancer. It is generally accepted that metabolic changes associated with overweight/obesity, particularly abdominal obesity and changes in adipocyte function, contribute to the increased risk of colon cancer. Understanding the mechanisms underlying this association is important for the development of preventive strategies for colon cancer. Part of these preventive strategies may be based on dietary factors, such as vitamins, minerals (e.g. selenium), fibre, phytochemicals and phenolic compounds. These anticancer nutrients may counteract the molecular changes associated with obesity. The present article reviews the evidence that inflammation and insulin resistance induced by obesity are the molecular mediators of the association between obesity and colon cancer. We also evaluate the evidence for the ability of dietary factors to target the obesity-induced changes and, thus, protect against colon cancer.

    The Great East Japan Earthquake of 2011 left many evacuees with insufficient food and emergency shelter. However, there is no evidence concerning the factors affecting dietary circumstances in emergency shelters after disasters. To clarify the factors that influenced the provision of meals, we reanalyzed a data set from a dietary survey conducted in emergency shelters one month after the Great East Japan Earthquake (2011). Among the 69 shelters in "city A," 53 (79.1%) had food shortages. The possibility of cooking in the emergency shelter improved the provision of meals to evacuees. When comparing emergency shelters with and without cooking equipment, the shelters with cooking equipment provided more meals, as well as more dishes containing grains and vegetables. When there was a gas supply, the twice per day provision of "balanced" meals (containing grains, vegetables, and meat/fish) was more frequent than when there was no gas supply. Interestingly, neither the water supply nor the electricity supply affected the provision of balanced meals. Further, emergency shelters with larger numbers of evacuees had a lower possibility of cooking and lower availability of gas supply. Our results demonstrate that early improvements to post-disaster meal provision may maintain the health of evacuees. Such improvements could be achieved by 1) the speedy restoration of the gas supply to enable cooking, and 2) limiting the number of evacuees per emergency shelter.

    The main purpose of this study was to explore some of the social, dietary and lifestyle factors that could be related to the risk of obesity among adolescents in Bahrain. A multistage stratified method was used to select secondary school students (15-18years old) from governmental schools in Bahrain. The total sample selected was 735 (339 males and 396 females). A pre-validated self-report questionnaire was used to obtain information on socio-demographics, food and the lifestyle habits of adolescents. Weight and height were taken and percentiles of Body Mass Index for age and gender were used to classify the adolescents as non-obese and obese (overweight and obese), using NHANES-1 growth standard. In general, the prevalence of overweight and obesity was 29.5% and 36.8% among males and females, respectively. The risk of obesity was not consistent among male and female adolescents. Mothers' education was found to be a risk factor for obesity among both males and females (p=0.0167 and p=0.007, respectively). Bringing food from home to school (odds ratio (OR)=0.54, confidence interval (CI) 0.35-0.81) was protective factor for obesity among females but not among males. Fathers' education (p=0.0167), rank among siblings (p=0.009), place where breakfast is eaten (p=0.0398), eating between lunch and dinner (p=0.0152), fruit intake (p=0.042), sweet intake (p=0.0192), size of burger (p=0.002) and hours of watching television per day (p=0.004) were significantly associated with the risk of obesity among males, but not among females. Various social, dietary and lifestyle factors were found to contribute to obesity among adolescents in Bahrain. These factors should be considered in school health policy in the country.

    Full Text Available Background: The relationship between diet and cardiovascular risk factors in men and women with Coronary Artery Disease (CAD has been the subject of recent studies. We studied a group of Iranian CAD patients to analyze any relationship between diet and CAD risk factors based on gender. Methods: In this study, 461 consecutive patients were assessed before their planned isolated coronary artery bypass graft surgery. They were interviewed to obtain the quantity and components of nutrients and micronutrients based on a validated food frequency questionnaire. Diet scores were calculated in each dietary group and the total score was reported as the Mediterranean Diet Quality Index (Med-DQI. Physical activity was assessed using International Physical Activity Questionnaire (IPAQ. Functional class, EuroSCORE and the frequency of the known risk factors in the men and women were recorded as well. Results: The women were more likely than the men to present with obesity, diabetes mellitus, hypercholesterolemia, and hypertension (all Ps < 0.001. Also, the women had higher functional class and mean of EuroSCORE (P < 0.001 and P = 0.03. Only six women (5.7% reported to have regular physical activity. In addition, Women’s energy intake was more likely to be supplied through fat. Cereals, fruit, and vegetable consumption in both genders was within the safe recommended range, while olive and fish consumption was low in both sexes. MedDQI score was different between men and women with hypertension (P = 0.018 and obesity (P = 0.048. Conclusions: Modifiable classical risk factors for CAD, except for smoking, were more prevalent in women and were associated with their diet. Therefore, women probably need to maintain low calorie intake while improving physical activity and dietary patterns to decrease the frequency and severity of modifiable cardiac risk factors.

    Diet interventions may reduce the risk of urinary stone formation and its recurrence, but there is no conclusive consensus in the literature regarding the effectiveness of dietary interventions and recommendations about specific diets for patients with urinary calculi. The aim of this study was to review the studies reporting the effects of different dietary interventions for the modification of urinary risk factors in patients with urinary stone disease. A systematic search of the Pubmed database literature up to July 1, 2014 for studies on dietary treatment of urinary risk factors for urinary stone formation was conducted according to a methodology developed a priori. Studies were screened by titles and abstracts for eligibility. Data were extracted using a standardized form and the quality of evidence was assessed. Evidence from the selected studies were used to form evidence-based guideline statements. In the absence of sufficient evidence, additional statements were developed as expert opinions. General measures: Each patient with nephrolithiasis should undertake appropriate evaluation according to the knowledge of the calculus composition. Regardless of the underlying cause of the stone disease, a mainstay of conservative management is the forced increase in fluid intake to achieve a daily urine output of 2 liters. HYPERCALCIURIA: Dietary calcium restriction is not recommended for stone formers with nephrolithiasis. Diets with a calcium content ≥ 1 g/day (and low protein-low sodium) could be protective against the risk of stone formation in hypercalciuric stone forming adults. Moderate dietary salt restriction is useful in limiting urinary calcium excretion and thus may be helpful for primary and secondary prevention of nephrolithiasis. A low-normal protein intake decrease calciuria and could be useful in stone prevention and preservation of bone mass. Omega-3 fatty acids and bran of different origin decreases calciuria, but their impact on the urinary

    2014-11-17

    Type 1 diabetes (T1D) is an autoimmune disease ultimately leading to destruction of insulin secreting β-cells in the pancreas. Genetic susceptibility plays an important role in T1D etiology, but even mono-zygotic twins only have a concordance rate of around 50%, underlining that other factors than purely genetic are involved in disease development. Here we review the influence of dietary and environmental factors on T1D development in humans as well as animal models. Even though data are still inconclusive, there are strong indications that gut microbiota dysbiosis plays an important role in T1D development and evidence from animal models suggests that gut microbiota manipulation might prove valuable in future prevention of T1D in genetically susceptible individuals.

    Full Text Available CONTEXT AND OBJECTIVE: Diet and nutrition are environmental factors in health/disease relationships. From the epidemiological viewpoint, diet represents a complex set of highly correlated exposures. Our objective was to identify patterns of food intake in a group of individuals living in São Paulo, and to develop objective dietary measurements for epidemiological purposes. DESIGN AND LOCAL: Exploratory factor analysis of data in a case-control study in seven teaching hospitals in São Paulo. METHODS: The participants were 517 patients (260 oral cancer cases and 257 controls admitted to the study hospitals between November 1998 and March 2001. The weekly intake frequencies for dairy products, cereals, meat, processed meat, vegetables, pulses, fruits and sweets were assessed by means of a semi-quantitative food frequency questionnaire. Dietary patterns were identified by factor analysis, based on the intake of the eight food groups, using principal component analysis as an extraction method followed by varimax rotation. RESULTS: Factor analysis identified three patterns that accounted for 55% of the total variability within the sample. The first pattern ("prudent" was characterized by vegetable, fruit and meat intake; the second ("traditional" by cereals (mainly rice and pulses (mainly beans; and the third ("snacks" by dairy products and processed meat. CONCLUSION: This study identified food intake patterns through an a posteriori approach. Such analysis may be useful for nutritional intervention programs and, after computing scores for each individual according to the patterns identified, for establishing a relationship between diet and other epidemiological measurements of interest.

    Most studies regarding low-carbohydrate diets (LCDs) have been intervention studies. The aim of the current study was to investigate dietary intake and cardiovascular risk factors among individuals who voluntarily follow a LCD. A cross-sectional study was conducted (N = 54, 20-66yrs) in Reykjavik, Iceland. Participants recorded food intake for three days. Blood samples were analyzed for cardiovascular risk factors. Nearly half of the participants were obese and around 60% had been on a LCD for ≥ 6 months. Fifty percent claimed they had lost weight during the past month. The median intake of carbohydrate, protein and fat were 8%, 22% and 68% E (hereof 25% saturated fatty acids), respectively. The consumption of bread and wholegrain cereals was very low (intake of dietary fiber (11g/day). Median fruit intake was 12 g/day. Intake of red meat and meat products was double that of the general population or ~900 g/week. Median intake of vitamins and minerals were mostly higher than the estimated average requirements. Cardiovascular risk factors were mostly within normal range. Mean blood lipids were slightly elevated although the high density lipoprotein/total cholesterol ratio was normal. Despite poor diet quality and high prevalence of obesity, individuals who voluntarily follow a LCD have cardiovascular risk factors mostly within reference range. These individuals consume very low amounts of carbohydrates and high amounts of fat and saturated fat acids. Intake of red meat and processed meat exceeds recommended intake. Very low intake of whole grain cereals and fruits results in low intake of fiber. Long term health implications need to be examined further in longitudinal studies.

    There has been no data on population based dietary patterns during the Ramadan fasting month. The purpose of this study was to detect Ramadan major dietary patterns among those who fast in Tehran. This cross-sectional study included 600 subjects, aged 18-65 with body mass index (BMI) of 18.5-40, who had decided to fast during Ramadan. Anthropometric measurements, usual physical activity level and educational status were collected two weeks before Ramadan. Information on Ramadan dietary intakes was obtained using a food frequency questionnaire and factor analysis was used to identify major dietary patterns. We identified four major dietary patterns: 1) Western-like pattern; high in fast foods, salty snacks, nuts, potato, fish, poultry, chocolates, juices; 2) high cholesterol and high sweet junk food pattern; high in pickles, sweets and condiments, butter and cream, canned fish, visceral meats and eggs; 3) Mediterranean-like pattern; high in vegetables, olive oil, dates, dairy, dried fruits, fruits, red meats, tea and coffee and 4) Ramadan-style pattern; large consumption of Halim, soups, porridges, legumes and whole grains, soft drinks, Zoolbia and Bamieh. Age was positively and inversely associated with Mediterranean-like (P = 0.003; r = 0.17) and Ramadan style (P = 0.1; r = -0.13) dietary pattern, respectively. Pre-Ramadan physical activity level was associated with a Mediterranean-like dietary pattern (P < 0.0001; r = 0.20). This study showed a Ramadan-specific dietary pattern has unique characteristics, which has not yet been identified as a model of dietary pattern. Also, among identified dietary patterns, Mediterranean-like was the healthiest.

    This study was conducted to determine factors that promote success in an introductory college computer science course and to determine what, if any, differences appear between genders on those factors. The model included math background, attribution for success/failure, self-efficacy, encouragement, comfort level in the course, work style preference, previous programming experience, previous non-programming computer experience, and gender as possible predictive factors for success in the computer science course. Subjects included 105 students enrolled in an introductory computer science course. The study revealed three predictive factors in the following order of importance: comfort level (with a positive influence), math background (with a positive influence), and attribution to luck (with a negative influence). No significant gender differences were found in these three factors. The study also revealed that both a formal class in programming (which had a positive correlation) and game playing (which had a negative correlation) were predictive of success. The study revealed a significant gender difference in game playing with males reporting more experience with playing games on the computer than females reported.

    The objective of this study was to determine associated factors to the consumption of fruit and vegetables (FV) in the adult population of each socioeconomic status (SES) in Bucaramanga, Colombia. We conducted a cross-sectional in a sample of 317 people and we measured socio-demographic, economic and anthropometric variables and dietary factors related to the purchase and consumption of FV. We made a survey, a 24-Hour dietary recall and we did anthropometric measurements. Portion sizes were estimated with a standardized set of utensils and food-photography atlas. Frequencies, measures of central tendency and dispersion were established and Logistic Regression models were used for the bi and multivariate analysis. Average consumption of FV was 162.6 g/day (188.5 g in high SES and 145.7 g in low SES, p = 0.056). On average 2 servings per day of FV (2.3 servings in high SES and 1.5 in low SES, p = 0.055). The prevalence of adequate intake of FV (more than 5 servings / day) was 8.6% (8.9% in high SES and 8.4% in low SES, p = 0.896). The associated factor to consumption of FV was BMI > or =25 (OR: 0.31, CI (95%): 0.11-0.89, p = 0.030), adjusted for occupation, income, SES, and number of family members. FV consumption is low; excess weight is the only variable associated to no-consumption of five or more servings; causes: cost to the consumption of fruit and flavor in the case of vegetables.

    This study aimed to explore the socio-demographic and dietary factors that may be associated with obesity among female university students in Jordan. A cross-sectional survey was carried out among 406 female students recruited from two universities in Jordan. Data were collected through self-reporting, using a previously validated questionnaire. Weight and height were measured and body mass index was calculated to determine the weight status of the participants. High educational level of mothers [odds ratio (OR)=1.25] and monthly pocket money of more than 200 Jordanian Dinars (OR=1.67) were found to be risk factors for obesity, whereas a sibling ranking of more than six was a protective factor (OR=0.31). Those who were eating from the university cafeteria had double the risk for obesity (OR=2.41) than those who did not. Regular eating of meals and snacking between meals were found to be protective factors (OR ranged from 0.42 to 0.79). Regular consumption of milk products, fruit, canned fruit juices, bakery products and legumes were found to be protective factors. In contrast, the regular consumption of potato chips (OR=1.35), chicken (OR=1.51), and fish (OR=1.45) were found to be risk factors for obesity. Using a chi-square test, none of the factors studied showed significant association with obesity. A program to promote healthy eating among university students in Jordan should consider the local socio-demographic and food behavior factors that could be related to obesity to ensure the effectiveness of such a program.

    Full Text Available Introduction: The effects of dietary glycemic load (GL on cardiometabolic risk factors in physically active subjects are not completely known. Objective: This cross-sectional study assessed the association of habitual dietary GL with cardiometabolic risk factors in physically active Brazilian middle-aged men. Methods: One-hundred seventy-six subjects (Age: 50.6 ± 5.0 years, BMI: 25.5 ± 3.6 kg/m² were evaluated. Anthropometry, lifestyle features, insulin resistance, oxidative stress biomarkers (8-iso-prostaglandin F2α; 8-iso-PGF2α and 8-hydroxydeoxyguanosine; 8-OHdG and lipid profile were assessed. Dietary intake was estimated through a quantitative food frequency questionnaire. Results: The dietary GL was positively associated with free fatty acid concentrations (β = 0.311, r² = 0.13, P-value = 0.034 and triglycerides/HDL cholesterol ratio (β = 0.598, r² = 0.19, P-value = 0.028 regardless of confounding factors (central obesity, red meat consumption, age and energy intake. The oxidative stress biomarker, 8-OHdG, was associated with habitual dietary GL (β = 0.432, r² = 0.11, P-value = 0.004, regardless of previous confounding factors plus excessive alcohol consumption, iron intake and current smoking status. Conclusions: The dietary GL was positively associated with lipid profile (free fatty acid concentrations and triglycerides/HDL cholesterol ratio and oxidative stress biomarker (8-OHdG. These results indicate potential harmfulness of diet with higher GL to cardiometabolic risk factors in middle-aged men, even in physically active individuals.

    Full Text Available The objectives were to assess total dietary fiber intake, identify the major sources of dietary fiber, and examine its association with socio-economic factors among Flemish preschoolers. Three-day estimated dietary records were collected from a representative sample of preschoolers 2.5–6.5 years old (n = 661; 338 boys, 323 girls. The mean dietary fiber intake (13.4 g/d was lower than the intake level recommended by the Belgian Superior Health Council (70% boys and 81% girls below the guidelines. The most important contributor was the group of bread and cereals (29.5%, followed by fruits (17.8%, potatoes and grains (16.0%, energy-dense, low-nutritious foods (12.4%, and vegetables (11.8%. Multiple linear regression analyses showed that total fiber intake was associated with maternal education and parents’ employment. Overall, fiber intakes from high-nutritious foods (vegetables and fruits were higher in preschoolers of higher educated mothers and those with one or both parents being employed. In conclusion, the majority of the preschoolers had dietary fiber intakes below the recommended level. Hence, dietary fiber should be promoted among parents of preschoolers and low socio-economic status families should be addressed in particular.

    This study was a cross-sectional survey conducted among 122 women workers employed in the electronics factories in the Ulu Klang Free Trade Zone (FTZ) and the Bangi FTZ, Selangor, Peninsular Malaysia. The purpose of the study was to examine the problem of overweight (>25.0 kg/m2) among this group of women, and factors (socio-demographic, work, exercise, and dietary) associated with overweight, and, to study the food intake pattern of the women in both the overweight and non-overweight groups. Data was collected using a set of questionnaires, while anthropometric measurements were obtained to calculate body mass index (BMI) and waist hip ratio (WHR). The results of the study indicated that 64.0% of the women were overweight (29.5% pre-obese, 34.5% obese). About one-tenth of the women (11.5%) had a WHR of above 0.85. From the bivariate analysis, it was found that women who were older, ever married, had lower educational level, had higher salary, not living in the hostel, involved in shiftwork, and trying to lose weight were more likely to be overweight. After adjusting for age, each of the above factors, except for educational level, remained significantly associated with overweight. Women's diet was found to be monotonous and lacking in variety as accessibility to and availability of a variety of food was a problem for them due to the nature of their work. They also had a sedentary lifestyle. Therefore, further research focusing on changing the poor dietary habits and sedentary lifestyle of the women workers is necessary to address the problem of overweight.

    Inadequate vitamin D status is highly prevalent in the Korean population, especially among young adults. Nonetheless, correlates of suboptimal vitamin D levels in young adults are not well defined. This study aimed to investigate potentially modifiable determinants of vitamin D levels in young adults in Korea. This cross-sectional study was based on health check-up data from 3,450 healthy male and female university students aged 18-29 yr in Seoul between April and May 2013. Serum 25-hydroxyvitamin D [25(OH)D] levels were determined using chemiluminescent immunoassay. Anthropometric data were measured, and lifestyle, dietary, and sociodemographic factors were obtained through self-administered questionnaires. General linear regression was used to assess correlates of serum 25(OH)D levels. The mean serum 25(OH)D level was 11.1 ng/mL, and the prevalence of 25(OH)D levels less than 10 ng/mL was 44.7% (39.5% in men, 50.2% in women). In a final multivariable model, significant positive correlates of serum 25(OH)D were older age, male sex, increased physical activity, sunlight exposure ≥ 30 min/day, eating breakfast regularly, consumption of dairy and fatty fish, and use of vitamin D-containing supplements. In contrast, significant inverse correlates were obesity (body mass index, BMI ≥ 25 kg/m(2)) or underweight (BMI instant noodles and sugar-sweetened beverages. In conclusion, many modifiable lifestyle and dietary factors were associated with low serum 25(OH)D levels in Korean young adults. Further studies on potential mechanisms of the correlates and optimal strategies to improve vitamin D status in this vulnerable subpopulation are warranted.

    United States Army personnel in garrison who are not deployed to combat theater report using dietary supplements (DSs) to promote health, increase physical and mental strength, and improve energy levels. Given the substantial physical and cognitive demands of combat, DS use may increase during deployment. This study compared DS use by garrison soldiers with DS use by personnel deployed to a combat theater in Afghanistan. Prevalence and patterns of DS use, demographic factors, and health behaviors were assessed by survey (deployed n = 221; garrison n = 1001). Eighty-two percent of deployed and 74% of garrison soldiers used DSs ≥ 1 time·week(-1). Logistic regression analyses, adjusted for significant demographic and health predictors of DS use, showed deployed personnel were more likely than garrison soldiers to use protein, amino acids, and combination products. Deployed females were more likely to use protein supplements and deployed males were more likely to use multivitamins, combination products, protein, and body building supplements than garrison respondents. Significantly more deployed (17%) than garrison (10%) personnel spent more than $50∙month(-1) on DSs. Higher protein supplement use among deployed personnel was associated with higher frequency of strength training and lower amounts of aerobic exercise for males but similar amounts of strength training and aerobic exercise for females. Protein supplements and combination products are used more frequently by deployed than garrison soldiers with the intent of enhancing strength and energy.

    Full Text Available BACKGROUND: Knowledge of the number of deaths caused by risk factors is needed for health policy and priority setting. Our aim was to estimate the mortality effects of the following 12 modifiable dietary, lifestyle, and metabolic risk factors in the United States (US using consistent and comparable methods: high blood glucose, low-density lipoprotein (LDL cholesterol, and blood pressure; overweight-obesity; high dietary trans fatty acids and salt; low dietary polyunsaturated fatty acids, omega-3 fatty acids (seafood, and fruits and vegetables; physical inactivity; alcohol use; and tobacco smoking. METHODS AND FINDINGS: We used data on risk factor exposures in the US population from nationally representative health surveys and disease-specific mortality statistics from the National Center for Health Statistics. We obtained the etiological effects of risk factors on disease-specific mortality, by age, from systematic reviews and meta-analyses of epidemiological studies that had adjusted (i for major potential confounders, and (ii where possible for regression dilution bias. We estimated the number of disease-specific deaths attributable to all non-optimal levels of each risk factor exposure, by age and sex. In 2005, tobacco smoking and high blood pressure were responsible for an estimated 467,000 (95% confidence interval [CI] 436,000-500,000 and 395,000 (372,000-414,000 deaths, accounting for about one in five or six deaths in US adults. Overweight-obesity (216,000; 188,000-237,000 and physical inactivity (191,000; 164,000-222,000 were each responsible for nearly 1 in 10 deaths. High dietary salt (102,000; 97,000-107,000, low dietary omega-3 fatty acids (84,000; 72,000-96,000, and high dietary trans fatty acids (82,000; 63,000-97,000 were the dietary risks with the largest mortality effects. Although 26,000 (23,000-40,000 deaths from ischemic heart disease, ischemic stroke, and diabetes were averted by current alcohol use, they were outweighed by

    RNA interference (RNAi) high-content screening (HCS) enables massive parallel gene silencing and is increasingly being used to reveal novel connections between genes and disease-relevant phenotypes. The application of genome-scale RNAi relies on the development of high quality HCS assays. The Z' factor statistic provides a way to evaluate whether or not screening run conditions (reagents, protocols, instrumentation, kinetics, and other conditions not directly related to the test compounds) are optimized. Z' factor, introduced by Zhang et al., ( 1) is a dimensionless value that represents both the variability and the dynamic range between two sets of sample control data. This paper describe a new extension of the Z' factor, which integrates bioinformatics RNAi non-target compounds for screening quality assessment. Currently presented Z' factor is based on positive and negative control, which may not be sufficient for RNAi experiments including oligonucleotides (oligo) with lack of knock-down. This paper proposes an algorithm which extends existing algorithm by using additional controls generetaed from on-target analysis.

    Full Text Available Abstract Background The aim of this study was to determine which behavioral factors to include in guidelines for the Japanese public to achieve an acceptable level of oral healthiness. The objective was to determine the relationship between oral health related behaviors and symptoms related to oral disease and tooth loss in a Japanese adult community. Methods Oral health status and lifestyle were investigated in 777 people aged 20 years and older (390 men and 387 women. Subjects were asked to complete a postal questionnaire concerning past diet and lifestyle. The completed questionnaires were collected when they had health examinations. The 15 questions included their preference for sweets, how many between-meal snacks they usually had per day, smoking and drinking habits, presence of oral symptoms, and attitudes towards dental visits. Participants were asked about their behaviors at different stages of their life. The oral health examinations included examination of the oral cavity and teeth performed by dentists using WHO criteria. Odds ratios were calculated for all subjects, all 10 year age groups, and for subjects 30 years or older, 40 years or older, 50 years or older, and 60 years or older. Results Frequency of tooth brushing (OR = 3.98, having your own toothbrush (OR = 2.11, smoking (OR = 2.71 and bleeding gums (OR = 2.03 were significantly associated with number of retained teeth in males. Frequency of between-meal snacks was strongly associated with number of retained teeth in females (OR = 4.67. Having some hobbies (OR = 2.97, having a family dentist (OR = 2.34 and consulting a dentist as soon as symptoms occurred (OR = 1.74 were significantly associated with number of retained teeth in females. Factors that were significantly associated with tooth loss in both males and females included alcohol consumption (OR = 11.96, males, OR = 3.83, females, swollen gums (OR = 1.93, males, OR = 3.04, females and toothache (OR = 3.39, males, OR

    The single and combined effects of three healthy lifestyle behaviors-nonsmoking, being physically active, and having a high-quality diet-on survival were investigated among older people in the SENECA Study. This European longitudinal study started with baseline measurements in 1988-1989 and lasted until April 30, 1999. The study population consisted of 631 men and 650 women aged 70-75 years from Belgium, Denmark, Italy, The Netherlands, Portugal, Spain, and Switzerland. A lifestyle score was calculated by adding the scores of the lifestyle factors physical activity, dietary quality, and smoking habits. The single lifestyle factors and the lifestyle score were related to mortality. Even at ages 70-75 years, the unhealthy lifestyle behaviors smoking, having a low-quality diet, and being physically inactive were singly related to an increased mortality risk (hazard ratios ranged from 1.2 to 2.1). The risk of death was further increased for all combinations of two unhealthy lifestyle behaviors. Finally, men and women with all three unhealthy lifestyle behaviors had a three- to fourfold increase in mortality risk. These results underscore the importance of a healthy lifestyle, including multiple lifestyle factors, and the maintenance of it with advancing age.

    2008-06-15

    Liberalisation of the electricity market has led to Danish gas engine plants increasingly converting to the spot and regulating power markets. In order to offer regulating power, plants need to be able to start and stop the engines at the plants quickly. The liberalisation causes a considerable change of operation practice of the engines e.g. less full load operation hours /year. The project provides an inventory determining the scale of the emissions during the start and stop sequence as well as proposals for engine modifications aimed at reducing start/stop emissions. This report includes calculation of emission factors as well as an inventory of total emissions and reduction potentials. (au)

    The study objective was to evaluate independent and interactive associations of dietary fiber intake and high urinary enterolignans with cardiometabolic risk factors. The analysis included 2260 adults (≥20 y of age) from the 2003-2010 NHANES. Logistic regression models were used to evaluate obesity and clinically defined cardiometabolic risk factors in relation to dietary fiber intake and urinary enterolignan concentrations. Three sets of models were created: 1) independent associations, 2) mutually adjusted associations, and 3) interactions. Models were adjusted for age, gender, race/ethnicity, education, smoking status, and energy intake. High concentrations were considered to be above the 90th percentile of urinary enterolignan concentrations. Increasing dietary fiber intake was associated with high blood pressure (P = 0.02) and low serum HDL cholesterol (P-trend = 0.03). High urinary enterodiol concentration was not associated with obesity or cardiometabolic risk factors. High urinary enterolactone concentration was inversely associated with obesity (OR: 0.44; 95% CI: 0.29, 0.66), abdominal obesity (OR: 0.58; 95% CI: 0.39, 0.87), high serum C-reactive protein (CRP; OR: 0.52; 95% CI: 0.37, 0.74), high serum triglycerides (OR: 0.39; 95% CI: 0.23, 0.61), low serum HDL cholesterol (OR: 0.37; 95% CI: 0.23, 0.61), and metabolic syndrome (OR: 0.47; 95% CI: 0.30, 0.74). In mutually adjusted models, enterolactone associations observed in independent models remained similar, but associations for dietary fiber intake were attenuated, with the exception of blood pressure. In interaction models, there were 2 significant interactions: between high urinary enterodiol concentration and dietary fiber intake for high serum CRP (P = 0.04) and high plasma glucose (P = 0.04). Overall, being in the highest 10% of urinary enterolactone concentration was associated with cardiometabolic risk factors, independent of dietary fiber intake and enterodiol concentration.

    Few epidemiological studies have assessed the relationship between the traditional Japanese dietary pattern and longitudinal changes in cardiovascular disease risk factors among Japanese people. We designed a 3-year longitudinal study of 980 subjects living in Japan to evaluate how the Japanese dietary pattern is related to longitudinal changes in well-recognized risk factors for cardiovascular disease among apparently healthy Japanese adults. Dietary consumption was assessed via a validated food frequency questionnaire. Principal component analysis was used to derive three major dietary patterns-"Japanese," "sweets-fruits-cooked wheaten food," and "Izakaya (Japanese Pub)" from 39 food groups. After adjustment for potential confounders, the mean (95% confidence interval) for the change per year in diastolic blood pressure for men, systolic blood pressure, and diastolic blood pressure for women related to the "Japanese" dietary pattern factor score tertiles were 0.89 (0.10, 1.68), 2.25 (0.19, 4.31), and 0.75 (-1.00, 2.50) for the lowest tertile, 0.77 (-0.02, 1.56), 1.01 (-1.13, 3.15), and 0.44 (-1.38, 2.26) for the middle tertile and - 0.04 (-0.81, 0.72), -0.48 (-2.52, 1.56), and -0.77 (-2.51, 0.96) for the highest tertile (trend P value = 0.03, triglyceride concentration only in men (trend P value = 0.02). Greater adherence to a traditional Japanese diet was independently related to a decreased change every year in diastolic blood pressure in men and women and in systolic blood pressure in women over a 3-year follow-up period. The findings suggest that the "Japanese" dietary pattern appeared to be related to a fall in blood pressure, which might have a beneficial effect on cardiovascular disease. A randomized trial is required to clarify the underlying mechanism.

    Recent observational and experimental evidence suggests that diet may contribute to acne prevalence. To examine the differences in select dietary factors (glycemic index [GI], total sugar, added sugar, fruit/fruit juice, fruit/vegetables, vegetables, saturated fat, trans fat, and number of milk and fish servings per day) between groups of self-reported acne severity. Secondary objectives were to investigate the differences in food-aggravated acne beliefs and acne-specific quality-of-life between groups of self-reported acne severity. This study utilized a cross-sectional design. A total of 248 (115 male, 133 female) participants, age 18 to 25 years, completed questionnaires designed to measure self-reported acne severity, select dietary factors, food-aggravated acne beliefs, acne-specific quality-of-life, and anthropometric and demographic characteristics. The Block fat/sugar/fruit/vegetable food frequency questionnaire assessed usual dietary intake. Data were collected in New York City between January and May 2012. One-way between groups analysis of variance examined differences in dietary factors, anthropometric characteristics, and acne-specific quality-of-life between groups of self-reported acne. χ² tests compared food-aggravated acne beliefs and demographic characteristics between groups of self-reported acne. Compared with participants with no or mild acne, participants with moderate to severe acne reported greater dietary GI (Pdiet to aggravate or influence acne. This study suggests that diet, particularly dietary GI, saturated fat, trans fat, milk, and fish may influence or aggravate acne development. Future research is necessary to elucidate the proposed mechanisms linking diet and acne and determine the impact of medical nutrition therapy on acne development.

    Dietary patterns have been used to identify typical combinations of foods that may be associated with disease risks. We defined dietary patterns among 195,298 participants of the Multiethnic Cohort Study in Hawaii and Los Angeles in 1993-1996. Intakes of Food Guide Pyramid groups were calculated from a quantitative FFQ for subjects of 5 ethnic groups (African Americans, Hawaiians, Japanese Americans, Latinos, and whites). Three distinct dietary patterns, "Fat and Meat," "Vegetables," and "Fruit and Milk," were identified by exploratory factor analysis with a varimax rotation and validated by confirmatory factor analysis. Similar factor loadings were found for each of 10 ethnic-gender groups in stratified analyses. The odds ratios (OR) for being above the median scores for each factor were calculated. Age, gender, and ethnicity had relatively strong associations with dietary patterns whereas education showed only weak associations. BMI > or = 30 was strongly positively associated with the Fat and Meat pattern (OR = 2.14, 95% CI: 2.08-2.20, vs. BMI pattern (OR = 1.67, CI: 1.62-1.72, vs. nonsmokers) and inverse associations with the Vegetables (OR = 0.66, CI: 0.64-0.68) and Fruit and Milk patterns (OR = 0.53, CI: 0.52-0.55). Physical activity was positively associated with the Vegetables and Fruit and Milk patterns but not with the Fat and Meat pattern. These findings support the hypothesis that dietary patterns are influenced by interrelated sociocultural, demographic, and other lifestyle factors and may be useful in investigations of diet-disease relations.

    Little is known about dietary factors and non-Hodgkin's lymphoma (NHL) risk, although high intakes of animal protein and milk have been associated with NHL in two previous studies. As part of a population-based case-control study of agricultural and other risk factors for NHL in eastern Nebraska (USA), we examined the self- and proxy-reported frequency of consumption of 30 food items by 385 White men and women with NHL and 1,432 controls. Animal protein intake was not associated significantly with the risk of NHL, however, there was a nonsignificantly elevated risk of NHL among men with high milk consumption. Vitamin C, carotene, citrus fruit, and dark green vegetable intakes were inversely significantly related to the risk of NHL for men, but not for women. Among men, the odds ratios for the highest quartiles of both vitamin C and carotene intake were 0.6 (95% confidence intervals = 0.3-1.0). There were no meaningful differences in the associations of nutrient intakes and NHL risk between B- and T-cell lymphomas and histologic types. Risks for low intakes of vitamin C and carotene were greater among men and women with a family history of cancer, particularly a history of lymphatic or hematopoietic cancer among first-degree relatives.

    Full Text Available Abstract Background Prevalence of men with cardiometabolic risk factors (CMRF is increasing in Japan. Few studies have comprehensively examined the relation between lifestyles and CMRF. Methods We examined the baseline data from 3,498 male workers ages 19 to 69 years who participated in the high-risk and population strategy for occupational health promotion (HIPOP-OHP study at 12 large-scale companies throughout Japan. The physical activity of each participant was classified according to the International Physical Activity Questionnaire (IPAQ. Dietary intake was surveyed by a semi-quantitative Food Frequency Questionnaire. We defined four CMRF in this study as follows: 1 high blood pressure (BP: systolic BP ≥ 130 mmHg, or diastolic BP ≥ 85 mmHg, or the use of antihypertensive drugs; 2 dyslipidemia: high-density lipoprotein-cholesterol concentration 2. Results Those who had 0 to 4 CMRF accounted for 1,597 (45.7%, 1,032 (29.5%, 587 (16.8%, 236 (6.7%, and 44 (1.3% participants, respectively, in the Poisson distribution. Poisson regression analysis revealed that independent factors that contributed to the number of CMRF were age (b = 0.020, P Conclusions Alcohol intake, percent protein and total energy intake were positively associated, whereas drinking frequency and IPAQ were inversely associated, with the number of CMRF.

    There has been a thrilling development , as well as profound changes, in our understanding of the effect of fetal nutrition on the development and health of the child. The Norwegian Mother and Child Cohort Study (MoBa) is an ongoing nationwide population-based pregnancy cohort study that between 1999 and 2008 recruited 90,723 women with 106,981 pregnancies and 108,487 children. The objective of MoBa is to test specific etiologic hypotheses by estimating the association between exposures and diseases with a special focus on disorders that may originate in early life. An important aspect in this regard is maternal diet and nutritional status during pregnancy. Nutritional factors have long been considered to be important determinants of maternal and fetal health, and dietary information is currently being collected in a number of pregnancy cohorts in Europe and the United States. Thus far, pregnancy complications studied in MoBa are preterm birth, preeclampsia, and fetal growth; and the aim of this article is to report results of recently published studies of dietary factors in relation to these outcomes. Numerous studies are planned using MoBa data, and the aim is to add to the knowledge of the interplay between dietary factors, nonnutrients, and toxic dietary substances and epigenetic modulation on fetal development and health later in life.

    Most cancers are dependent on the growth of tumor blood vessels and inhibition of tumor angiogenesis may thus provide an efficient strategy to retard or block tumor growth. Recently, tumor vascular targeting has expanded to include not only endothelial cells (ECs) but also smooth muscle cells (SMCs), which contribute to a mature and functional vasculature. We have reported previously that delphinidin, a major biologically active constituent of berries, inhibits the vascular endothelial growth factor-induced phosphorylation of vascular endothelial growth factor receptor-2 and blocks angiogenesis in vitro and in vivo. In the present study, we show that delphinidin also inhibits activation of the platelet-derived growth factor (PDGF)-BB receptor-beta [platelet-derived growth factor receptor-beta (PDGFR-beta)] in SMC and that this inhibition may contribute to its antitumor effect. The inhibitory effect of delphinidin on PDGFR-beta was very rapid and led to the inhibition of PDGF-BB-induced activation of extracellular signal-regulated kinase (ERK)-1/2 signaling and of the chemotactic motility of SMC, as well as the differentiation and stabilization of EC and SMC into capillary-like tubular structures in a three-dimensional coculture system. Using an anthocyan-rich extract of berries, we show that berry extracts were able to suppress the synergistic induction of vessel formation by basic fibroblast growth factor-2 and PDGF-BB in the mouse Matrigel plug assay. Oral administration of the berry extract also significantly retarded tumor growth in a lung carcinoma xenograft model. Taken together, these results provide new insight into the molecular mechanisms underlying the antiangiogenic activity of delphinidin that will be helpful for the development of dietary-based chemopreventive strategies.

    The aim of this study was to provide additional evidences on prognostic factors for infantile spasms and the possible role of a ketogenic diet. A retrospective analysis was performed for patients with infantile spasms who had been followed up for more than 6months between January 2000 and July 2012 at Samsung Medical Center (Seoul, Republic of Korea). We analyzed the association between possible prognostic factors and seizure/developmental outcomes. Sixty-nine patients were included in this study and their mean follow-up duration was 52.5 (9-147) months. In the patients who had been followed up for more than 2years, 53.6% (n=30/57) remained seizure-free at the last visit. Sixty patients (86.9%) showed developmental delay at last follow-up. Forty-two patients (60.9%) became spasm-free with one or two antiepileptic drugs, one patient with epilepsy surgery for a tumor, and seven patients with a ketogenic diet after the failure of two or more antiepileptic drugs. The etiology and age of seizure onset were the significant prognostic factors. In this study, about 60% of the patients became spasm-free with vigabatrin and topiramate. Ketogenic diet increased the rate by 10% in the remaining antiepileptic drug resistant patients. However, 86.9% of the patients showed developmental delay, mostly a severe degree. Early diagnosis and prompt application of treatment options such as antiepileptic drugs, a ketogenic diet or epilepsy surgery can improve outcomes in patients with infantile spasms.

    Most studies analyzing diet-disease relations focus on single dietary factors rather than combining different nutrients into the same statistical model. The objective of this study was to identify dietary factors associated with the probability of having diabetes identified by screening (SDM) in Danish men and women aged 30-60 y. A specific objective was to examine whether an alternative statistical approach could provide additional information to already existing statistical approaches used in nutritional epidemiology. Baseline data from the Danish population-based Inter99 study were used. The dietary intake of 262 individuals with SDM was compared with that of 4627 individuals with normal glucose tolerance (NGT) using 2 different types of multiple logistic regression models adjusted for potential confounders. The first model included single dietary factors, whereas the second model was based on substitution of macronutrients. In the models with single dietary factors, high intakes of carbohydrates, dietary fiber, and coffee were inversely associated with SDM (P < 0.01), whereas high intakes of total fat and saturated fat were positively associated with SDM (P < 0.05). A modest U-shaped association was found between alcohol consumption and SDM (P = 0.10) [corrected] Results from the substitution model showed that when 3% of energy (En%) as carbohydrate replaced 3 En% fat or alcohol, the probability of having SDM decreased by 9 and 10%, respectively (P < 0.01) [corrected] No other macronutrient substitutions resulted in significant associations. Hence, the statistical approach based on substitution of macronutrients provided additional information to the model analyzing single dietary factors.

    Socioeconomic inequalities in physical activity at the individual level are well reported. Whether inequalities in economic development and other macroenvironmental variables between countries are also related to physical activity at the country level is comparatively unstudied. We examined the relationship between country-level data on macroenvironmental factors (gross domestic product (GDP) per capita, public sector expenditure on health, percentage living in urban areas, and cars per 1000 population) with country-level physical activity prevalence obtained from previous pan-European studies. Studies that assessed leisuretime physical activity (n = 3 studies including 27 countries in adults, n = 2 studies including 28 countries in children) and total physical activity (n = 3 studies in adults including 16 countries) were analyzed separately as were studies among adults and children. Strong and consistent positive correlations were observed between country prevalence of leisure-time physical activity and country GDP per capita in adults (average r = 0.70; all studies, P G 0.05). In multivariate analysis, country prevalence of leisure-time physical activity among adults remained associated with country GDP per capita (two of three studies) but not urbanization or educational attainment. Among school-age populations, no association was found between country GDP per capita and country prevalence of leisure-time physical activity. In those studies that assessed total physical activity (which also includes occupational and transport physical activity), no association with country GDP per capita was observed. Clear differences in national leisure-time physical activity levels throughout Europe may be a consequence of economic development. Lack of economic development of some countries in Europe may make increasing leisure-time physical activity more difficult.

    Full Text Available A consumer survey on dietary supplement consumption was carried out on 494 consumers aged 20 years and older in Chiang Mai province. The percentage of consumers who regularly consumed dietary supplements was 38.5%. Vitamins and minerals were the most consumed products, followed by functional drinks, functional foods, protein extracts, dietary fibre, cod liver oil, phytochemicals, algae products, fat absorbers, fish oils and bee products in that order. Females and participants who had recommended waistlines, had higher income, usually felt stressed or sick, and who preferred eating fruits/vegetables or routinely drank water tended to have a higher rate of consumption of dietary supplements. Participants gave priority over a product with guaranteed quality when they made decision to purchase dietary supplements, but their purchase was also influenced by the attractiveness of the product and advertisement for it.

    Previous research has shown, in predominantly European populations, that dietary patterns are evident early in life. However, little is known about early-life dietary patterns in Australian children. We aimed to describe dietary patterns of Australian toddlers and their associations with socio-demographic characteristics and adiposity. Principal component analysis was applied to 3 days (1 × 24-h recall and 2 × 24-h record) data of 14 (n=552)- and 24 (n=493)-month-old children from two Australian studies, NOURISH and South Australian Infant Dietary Intake (SAIDI). Associations with dietary patterns were investigated using regression analyses. Two patterns were identified at both ages. At 14 months, the first pattern was characterised by fruit, grains, vegetables, cheese and nuts/seeds ('14-month core foods') and the second pattern was characterised by white bread, milk, spreads, juice and ice-cream ('basic combination'). Similarly, at 24 months the '24-month core foods' pattern included fruit, vegetables, dairy, nuts/seeds, meat and water, whereas the 'non-core foods' included white bread, spreads, sweetened beverages, snacks, chocolate and processed meat. Lower maternal age and earlier breastfeeding cessation were associated with higher 'basic combination' and 'non-core foods' pattern scores, whereas earlier and later solid introduction were associated with higher 'basic combination' and '24-month core foods' pattern scores, respectively. Patterns were not associated with body mass index (BMI) z-score. Dietary patterns reflecting core and non-core food intake are identifiable in Australian toddlers. These findings support the need to intervene early with parents to promote healthy eating in children and can inform future investigations on the effects of early diet on long-term health.

    Background/Aims The prevalence of irritable bowel syndrome (IBS) has risen considerably over the past decade in Singapore. We aim to explore the contribution of changes in diet, lifestyle and habits that may contribute to the increased prevalence and development of IBS. Methods This is a survey-based cross-sectional population study aimed to gather demographic, socio-economical, lifestyle, dietary, antibiotic usage and other related information. Subjects were adult male or female Singaporeans aged 21 years or above. Association of the factors gathered with the presence or absence of IBS (by Rome III criteria) was assessed using chi-square or Fisher’s exact test. Variables with a level of statistical significance of 0.1 or less in the univariate analysis were entered into a stepwise logistic regression model. Results A total of 297 subjects participated in the study (female 60.3%). Overall, 20.9% subjects fulfilled the Rome III IBS criteria. Univariate analysis showed that IBS was associated with pet ownership, antibiotic usage, late dinner, (> 9 PM) and consumption of Western meals, coffee, and bread. The multivariate logistic regression analyses showed that IBS was independently associated with being a pet owner (P = 0.008; OR, 2.5; 95% CI, 1.278–5.037). Conclusions The prevalence of IBS was 20.9% using the Rome III criteria in our study. The association between IBS and pet ownership will need further investigation. PMID:26951047

    Full Text Available Several recent studies have described a strong correlation between nutritional or economic data and the number of Nobel awards obtained across a large range of countries. This sheds new light on the intriguing question of the key predictors of Nobel awards chances. However, all these studies have been focused on a single predictor and were only based on simple correlation and/or linear model analysis. The main aim of the present study was thus to clarify this debate by simultaneously exploring the influence of food consumption (cacao, milk, and wine, economic variables (gross domestic product and scientific activity (number of publications and research expenditure on Nobel awards. An innovative statistical analysis, hierarchical partitioning, has been used because it enables us to reduce collinearity problems by determining and comparing the independent contribution of each factor. Our results clearly indicate that a country's number of Nobel awards can be mainly predicted by its scientific achievements such as number of publications and research expenditure. Conversely, dietary habits and the global economy variable are only minor predictors; this finding contradicts the conclusions of previous studies. Dedicating a large proportion of the GDP to research and to the publication of a high number of scientific papers would thus create fertile ground for obtaining Nobel awards.

    The role of fever in trauma patients remains unclear. Fever occurs as a response to release of cytokines and prostaglandins by white blood cells. Many factors, including trauma, can trigger release of these factors. To determine whether (1) fever in the first 48 hours is related to a favorable outcome in trauma patients and (2) fever is more common in patients with head trauma. Retrospective study of trauma patients admitted to the intensive care unit for at least 2 days. Data were analyzed by using multivariate analysis. Of 162 patients studied, 40% had fever during the first 48 hours. Febrile patients had higher mortality rates than did afebrile patients. When adjusted for severity of injuries, fever did not correlate with mortality. Neither the incidence of fever in the first 48 hours after admission to the intensive care unit nor the number of days febrile in the unit differed between patients with and patients without head trauma (traumatic brain injury). About 70% of febrile patients did not have a source found for their fever. Febrile patients without an identified source of infection had lower peak white blood cell counts, lower maximum body temperature, and higher minimum platelet counts than did febrile patients who had an infectious source identified. The most common infection was pneumonia. No relationship was found between the presence of fever during the first 48 hours and mortality. Patients with traumatic brain injury did not have a higher incidence of fever than did patients without traumatic brain injury. About 30% of febrile patients had an identifiable source of infection. Further studies are needed to understand the origin and role of fever in trauma patients. ©2015 American Association of Critical-Care Nurses.

Data from the survey performed in the framework of the HAPIEE (Health, Alcohol, Psychosocial factors In Eastern Europe) study were presented. A random sample of 7,087 individuals aged 45-72 years was screened in 2006-2008. Factor analysis of the main dietary patterns revealed a five-factor solution, which accounted for 47.8% of the variance: "fresh vegetables and fruit"; "sweets"; "porridge and cereals"; "potatoes, meat, boiled vegetables and eggs"; "chicken and fish". "Fresh vegetables and fruits" factor and "sweets" factor were inversely associated with age both in men and women: older people consumed less frequent than average of the particular food groups. Dietary patterns of people with good self-rated health and university education were healthier than among people with lower education and poorer health. Nutrition education efforts should focus on improving food diversity, with particular targeting of lower educated, single and older people.

    The purpose of this study was to explain the health promotion behavior of Chinese international students in Korea using a structural equation model including acculturation factors. A survey using self-administered questionnaires was employed. Data were collected from 272 Chinese students who have resided in Korea for longer than 6 months. The data were analyzed using structural equation modeling. The p value of final model is .31. The fitness parameters of the final model such as goodness of fit index, adjusted goodness of fit index, normed fit index, non-normed fit index, and comparative fit index were more than .95. Root mean square of residual and root mean square error of approximation also met the criteria. Self-esteem, perceived health status, acculturative stress and acculturation level had direct effects on health promotion behavior of the participants and the model explained 30.0% of variance. The Chinese students in Korea with higher self-esteem, perceived health status, acculturation level, and lower acculturative stress reported higher health promotion behavior. The findings can be applied to develop health promotion strategies for this population. Copyright © 2016. Published by Elsevier B.V.

    Human diets rely on natural resource availability and can reflect social and cultural values. When environments, societies, and cultures change, diets may also shift. This study traced the extent of dietary change and the factors influencing such change. Through stable carbon and nitrogen isotopic analysis of late Neolithic and early Bronze Age human and animal bone collagen, we found that significant shifts in human diets were closely associated with intercontinental cultural exchanges in Eurasia and climate change in northwestern China. The isotopic evidence indicated that human diets mainly consisted of C4 foodstuffs (presumably millet and/or animals fed with C4 foods) around 4000 calibrated years before the present (cal yr BP), corresponding to the flourishing of millet agriculture in the context of the optimal climate conditions of the mid-Holocene. Subsequently, more C3 foods (probably wheat, barley, and animals fed with C3 foods) were added to human diets post-3600 cal yr BP when the climate became cooler and drier. Such dietary variation is also consistent with the increasing intensity of long-distance exchange after 4000 cal yr BP. While many factors can lead to human dietary shifts (e.g. climate change, population growth, cultural factors, and human migration), climate may have been a key factor in Gansu and Qinghai.

  20. Effects of dietary polyphenols on neuroregulatory factors and pathways that mediate food intake and energy regulation in obesity.

    Polyphenols are natural substances and are enriched in vegetables, fruits, grains, bark, tea, and wine. Some polyphenols have insulin-potentiating and anti-inflammatory effects, both of which are important in obesity. Dietary supplementation with polyphenolic compounds is associated with reduced diet-induced obesity and/or metabolic syndrome in animal and human studies. Insights into mechanisms that regulate food intake and satiety have led to an increased understanding of obesity but the pathogenesis underlying obesity is lacking. Food intake is subject to a complex regulation by the hypothalamus and other brain centers including the brain stem and the hippocampus. An intricate network of interacting feedback mechanisms that involve the aforementioned neural centers along with the stomach, gut, liver, thyroid, and adipose tissue in the periphery, influence the eventual outcome of food intake and satiety. Key peripheral signals, such as leptin, insulin, and ghrelin, have been linked to hypothalamic neuropeptide systems in energy regulation. This review will examine the neural centers important in food intake, the role of various neuropeptides, and the neurohormonal influence on food intake. The potential role of polyphenols in influencing the neuroregulatory factors, the neural signaling pathways and/or the peripheral feedback mechanisms that modulate food intake will also be examined. © 2012 WILEY-VCH Verlag GmbH & Co.

    Although a high prevalence of anemia and related disease burden have been documented in China, limited evidence is available on the current population-level iron status and risk factors for iron imbalance. We explored the associations of dietary, lifestyle, and sociodemographic factors with iron status in Chinese adults. Our study population consisted of 7672 adults aged 18-65 y from the 2009 China Health and Nutrition Survey. Diet was assessed with the use of 3 consecutive 24-h dietary recalls. Serum ferritin, serum transferrin receptor, and hemoglobin concentrations were measured. The geometric means ± SDs for ferritin concentrations were 135.9 ± 2.7 ng/mL in men and 42.7 ± 3.1 ng/mL in women. After adjustment for potential risk factors, including high-sensitivity C-reactive protein concentration, the association between age and ferritin concentration was inverse in men (P-trend ferritin concentration in both men and women (both P-trends ferritin concentration in men (P-trend = 0.002) but not in women. Red meat consumption was positively associated with ferritin concentration both in men (P-trend = 0.002) and in older women (P-trend = 0.009). Lower intakes of grains and higher intakes of pork and poultry were associated with higher ferritin concentrations (all P-trends ≤ 0.05) in men but not in women. We observed variations in ferritin concentrations across different geographic regions (both P ≤ 0.01). Serum ferritin concentrations varied across different sociodemographic, lifestyle, and dietary factors in this Chinese population. A higher intake of red meat was associated with higher ferritin concentrations in men and older women. © 2017 American Society for Nutrition.

    into account all the important factors. Another difficulty is that many past studies have relied on imprecise methods for the measurement of bone resorption. Nor have studies based on the use of the laboratory rat produced clear answers to the problem because the rat, as a species, is uniquely deficient in its ability to handle the relevant minerals. Limited studies to date indicate that increased sodium intake neither exerts a consistent effect on various biomarkers of bone health nor leads to irreversible changes in the bone modelling process in men or in pre- or postmenopausal women. We conclude from the available evidence that increased sodium (or salt) intake is not an important risk factor for osteoporosis and that a reduction of salt intake from 9 to 6g/day in the diet would not be beneficial as an intervention measure in the prevention of osteoporosis. More research is needed to (i) assess the effects (especially long-term) of various nutrients including sodium on bone health, (ii) assess the long-term value of any intervention strategy involving reduced intake of a particular nutrient such as sodium; and (iii) determine whether subpopulations exist particularly in the elderly (e.g. sodium-responsive subjects) in which adaptation to sodium-induced hypercalciuria may be compromised. General prudence dictates that excessively high levels of dietary salt should be eschewed by those persons with raised blood pressure or a limited range of genetic disorders. However, for the generally healthy person there is no sound evidence that the consumption of salt at the present average level of 9g/day constitutes a risk factor for osteoporosis.

    Although dietary supplements (DSs) in sports are considered a natural need resulting from athletes' increased physical demands, and although they are often consumed by athletes, data on DS usage in Olympic sailing are scarce. The aim of this study was to study the use of and attitudes towards DSs and doping problems in high-level competitive sailing. The sample consisted of 44 high-level sailing athletes (5 of whom were female; total mean age 24.13 ± 6.67 years) and 34 coaches (1 of whom was female; total mean age 37.01 ± 11.70). An extensive, self-administered questionnaire of substance use was used, and the subjects were asked about sociodemographic data, sport-related factors, DS-related factors (i.e., usage of and knowledge about DSs, sources of information), and doping-related factors. The Kruskal-Wallis ANOVA was used to determine the differences in group characteristics, and Spearman's rank order correlation and a logistic regression analysis were used to define the relationships between the studied variables. DS usage is relatively high. More than 77% of athletes consume DSs, and 38% do so on a regular basis (daily). The athletes place a high degree of trust in their coaches and/or physicians regarding DSs and doping. The most important reason for not consuming DSs is the opinion that DSs are useless and a lack of knowledge about DSs. The likelihood of doping is low, and one-third of the subjects believe that doping occurs in sailing (no significant differences between athletes and coaches). The logistic regression found crew number (i.e., single vs. double crew) to be the single significant predictor of DS usage, with a higher probability of DS consumption among single crews. Because of the high consumption of DSs future investigations should focus on real nutritional needs in sailing sport. Also, since athletes reported that their coaches are the primary source of information about nutrition and DSs, further studies are necessary to determine the

    OBJECTIVE To assess the factors associated with the use of dietary supplements by people who exercise at gyms.METHODS A cross-sectional study with a sample defined by convenience, considering the number of gyms registered in the Conselho Regional de Educação Física (Regional Council of Physical Education) of Sao Luis, MA, Northeastern Brazil, from July 2011 to July 2012. The final sample comprised 723 individuals who exercise at gyms. The dependent variable was supplement use, and the explanatory variables were length of time and motivation of the physical exercises, duration, goal and self-perception of training, weekly frequency of gym attendance, sex, age, educational attainment, self-perception of body weight, smoking and self-perception of diet. The association between variables was analysed by hierarchical Poisson regression based on a theoretical model.RESULTS Supplement use was reported by 64.7% of the participants. Most of the sample was male (52.6%). The most frequent age group was 20 to 39 years (74.4%). Most participants (46.1%) had been exercising for over a year. The following variables were associated with supplement use: self-perceiving body weight as below ideal (p gym (p = 0.051), and perceiving training as moderate (p = 0.024) or intense (p = 0.001).CONCLUSIONS The use of supplements lacks proper professional guidance, being motivated by individuals unsatisfied with their low body weight and who perceive their workout as intense, which raises the need for monitoring this population.

  9. Physical activity in the prevention and amelioration of osteoporosis in women : interaction of mechanical, hormonal and dietary factors.

    Borer, Katarina T

    2005-01-01

    Osteoporosis is a serious health problem that diminishes quality of life and levies a financial burden on those who fear and experience bone fractures. Physical activity as a way to prevent osteoporosis is based on evidence that it can regulate bone maintenance and stimulate bone formation including the accumulation of mineral, in addition to strengthening muscles, improving balance, and thus reducing the overall risk of falls and fractures. Currently, our understanding of how to use exercise effectively in the prevention of osteoporosis is incomplete. It is uncertain whether exercise will help accumulate more overall peak bone mass during childhood, adolescence and young adulthood. Also, the consistent effectiveness of exercise to increase bone mass, or at least arrest the loss of bone mass after menopause, is also in question. Within this framework, section 1 introduces mechanical characteristics of bones to assist the reader in understanding their responses to physical activity. Section 2 reviews hormonal, nutritional and mechanical factors necessary for the growth of bones in length, width and mineral content that produce peak bone mass in the course of childhood and adolescence using a large sample of healthy Caucasian girls and female adolescents for reference. Effectiveness of exercise is evaluated throughout using absolute changes in bone with the underlying assumption that useful exercise should produce changes that approximate or exceed the absolute magnitude of bone parameters in a healthy reference population. Physical activity increases growth in width and mineral content of bones in girls and adolescent females, particularly when it is initiated before puberty, carried out in volumes and at intensities seen in athletes, and accompanied by adequate caloric and calcium intakes. Similar increases are seen in young women following the termination of statural growth in response to athletic training, but not to more limited levels of physical activity

    The brain is an organ elaborated and functioning from substances present in the diet. Dietary regulation of blood glucose level (via ingestion of food with a low glycemic index ensuring a low insulin level) improves the quality and duration of intellectual performance, if only because at rest the adult brain consumes 50 p. 100 of dietary carbohydrates, 80 p. 100 of them for energy purposes. The nature of the amino acid composition of dietary proteins contributes to good cerebral function; tryptophan plays a special role. Many indispensable amino acids present in dietary proteins help to elaborate neurotransmitters and neuromodulators. Omega-3 fatty acids provided the first coherent experimental demonstration of the effect of dietary nutrients on the structure and function of the brain. First it was shown that the differentiation and functioning of cultured brain cells requires omega-3 fatty acids. It was then demonstrated that alpha-linolenic acid (ALA) deficiency alters the course of brain development, perturbs the composition and physicochemical properties of brain cell membranes, neurones, oligodendrocytes, and astrocytes (ALA). This leads to physicochemical modifications, induces biochemical and physiological perturbations, and results in neurosensory and behavioral upset. Consequently, the nature of polyunsaturated fatty acids (in particular omega-3) present in formula milks for infants (premature and term) conditions the visual and cerebral abilities, including intellectual abilities. Moreover, dietary omega-3 fatty acids are certainly involved in the prevention of some aspects of cardiovascular disease (including at the level of cerebral vascularization), and in some neuropsychiatric disorders, particularly depression, as well as in dementia, notably Alzheimer's disease. Their deficiency can prevent the satisfactory renewal of membranes and thus accelerate cerebral aging. Iron is necessary to ensure oxygenation, to produce energy in the cerebral parenchyma

    Carcinogenic chemicals act through DNA damage and mitogenic effects. No established mechanism explains the cancer preventive effects, if any, of food items, such as vegetables and fruit. If such data were available, preferably on tumor-initiating genes, the evidence for the protective effects would become stronger. The von Hipple-Lindau (VHL) gene is the tumor suppressor gene predisposing to both sporadic renal cell carcinoma (RCC) and von Hippel-Lindau disease. We have earlier analyzed VHL mutations in RCCs from 102 Swedish patients identified in a case-control study and here examine associations between patient characteristics, including dietary habits and mutations, considering the type of mutation. The results are given as odds ratios (OR), separately for smokers and all patients. In univariate analysis, consumption of vegetables and citrus fruit decreased the frequency of VHL mutations among smokers and citrus fruit among all patients. In multivariate analysis of smokers' characteristics, welding fumes showed a risk of 5.63 for multiple VHL mutations. In smokers, citrus fruit decreased the OR of GC to AT mutations to 0.13 and that of multiple mutations to 0.17; vegetables decreased the OR for single mutations to 0.22. Among all subjects, welding fumes were a risk factor and citrus fruit a protective factor. Additionally, an intake of selenium protected against multiple mutations. The present results provide evidence that the intake of vegetables, selenium and particularly of citrus fruit protects the renal VHL gene from mutational insults that may be endogenous or common in a population. Even though most of the associations are biologically plausible, and vegetables and fruit were an a priori hypothesis, fortuitous results cannot be ruled out in this relatively small study.

    To identify different dietary patterns in Norway using a combination of cluster and factor analysis. Cross-sectional study. Nation-wide, population-based study. The Norwegian EPIC cohort is a subcohort of the Norwegian Women and Cancer study (NOWAC), and consist 37.226 women aged 41-56 y who answered a food frequency questionnaire (FFQ) in 1998. The associations among 50 food variables were first investigated by using principal component analysis. Five important factors were found. The five principal components were then used as input in the cluster analysis. Different socioeconomic and lifestyle variables were examined. Six clusters of dietary patterns were found, and were labelled accordingly: 'traditional fish eaters', 'healthy eaters', 'average, less fish, less healthy', 'Western', 'traditional bread eaters', and 'alcohol users'. The traditional fish eaters and the traditional bread eaters were both highly represented in the north and west of Norway and were more likely to be present among persons with lower income and lower education. The healthy and the alcohol drinkers were found mostly in the south and east and were more likely to have higher income. Persons in the alcohol group were more likely to be current smokers. The western group had the highest percentage of three or more persons in the household and the shortest time since last birth, indicating that families with children dominate this group. Our data indicate six different dietary patterns in Norway, each with different socio-demographic and lifestyle characteristics. The Norwegian Cancer Society (E 04038/006).

    This Comment by the Committee on Nutrition of the European Society for Paediatric Gastroenterology, Hepatology, and Nutrition aims to provide a summary of the role of nutrition-related factors on obesity prevention in children ages 2 to 18 years. This Comment emphasizes that dietary interventions should be incorporated into a multidisciplinary strategy for obesity prevention. No single nutrient has been unequivocally associated with the development of obesity. Methodological limitations in study design and the complex nature of obesity must be taken into account when interpreting the association with reported dietary factors. Energy intake should be individually determined, taking into account energy expenditure and growth. Preferential intake of slowly absorbed carbohydrates and limiting the ingestion of rapidly absorbed carbohydrates and simple sugars should be promoted. No specific recommendations for macronutrient intakes to prevent obesity can be made. Plant foods can be used as the main food contributors to a well-balanced diet with adequate monitoring of nutrient intake. Plain water should be promoted as the main source of fluids for children instead of sugar-sweetened beverages. Children should eat at least 4 meals, including breakfast, every day. Regular family meals should be encouraged. Regular consumption of fast food with large portion sizes and high energy density should be avoided. Healthy food options should be promoted for snacking. Food portion sizes should be appropriate for age and body size. Nutrition and lifestyle education aimed at the prevention of obesity should be included in the routine care of children by health care professionals.

    Full Text Available Abstract The subjective nature of self-reported dietary intake assessment methods presents numerous challenges to obtaining accurate dietary intake and nutritional status. This limitation can be overcome by the use of dietary biomarkers, which are able to objectively assess dietary consumption (or exposure without the bias of self-reported dietary intake errors. The need for dietary biomarkers was addressed by the Institute of Medicine, who recognized the lack of nutritional biomarkers as a knowledge gap requiring future research. The purpose of this article is to review existing literature on currently available dietary biomarkers, including novel biomarkers of specific foods and dietary components, and assess the validity, reliability and sensitivity of the markers. This review revealed several biomarkers in need of additional validation research; research is also needed to produce sensitive, specific, cost-effective and noninvasive dietary biomarkers. The emerging field of metabolomics may help to advance the development of food/nutrient biomarkers, yet advances in food metabolome databases are needed. The availability of biomarkers that estimate intake of specific foods and dietary components could greatly enhance nutritional research targeting compliance to national recommendations as well as direct associations with disease outcomes. More research is necessary to refine existing biomarkers by accounting for confounding factors, to establish new indicators of specific food intake, and to develop techniques that are cost-effective, noninvasive, rapid and accurate measures of nutritional status.

    Full Text Available Aims. To evaluate the prognostic significance of serum interleukin-6 (IL-6 in colorectal cancer (CRC. Patients and Methods. Preoperative serum IL-6 was measured in 233 CRC patients and 13 healthy controls. Relationships between IL-6 and various clinicopathological factors were evaluated, and the overall survival (OS and disease-free survival (DFS rates according to IL-6 status were calculated for all patients and according to disease stage. Results. The mean IL-6 level was 6.6 pg/mL in CRC patients and 2.6 pg/mL in healthy controls. Using a cutoff of 6.3 pg/mL, obtained using receiver operating characteristic curve analysis, 57 patients had a high IL-6 level. The mean value was higher for stage II disease than for stage III disease. IL-6 status correlated with C-reactive protein (CRP and carcinoembryonic antigen levels, obstruction, and pT4 disease. The OS differed according to the IL-6 status for all patients, whereas the DFS differed for all patients and for those with stage II disease. The Cox proportional hazards model showed that pT4 disease was an independent risk factor for recurrence in all CRC patients; IL-6, CRP, and pT4 were significant risk factors in stage II patients. Conclusions. The preoperative IL-6 level influences the risk of CRC recurrence.

  3. Current Changes in Pubertal Timing: Revised Vision in Relation with Environmental Factors Including Endocrine Disruptors.

    The aim of this chapter is to revise some common views on changes in pubertal timing. This revision is based on recent epidemiological findings on the clinical indicators of pubertal timing and data on environmental factor effects and underlying mechanisms. A current advancement in timing of female puberty is usually emphasized. It appears, however, that timing is also changing in males. Moreover, the changes are towards earliness for initial pubertal stages and towards lateness for final stages in both sexes. Such observations indicate the complexity of environmental influences on pubertal timing. The mechanisms of changes in pubertal timing may involve both the central neuroendocrine control and peripheral effects at tissues targeted by gonadal steroids. While sufficient energy availability is a clue to the mechanism of pubertal development, changes in the control of both energy balance and reproduction may vary under the influence of common determinants such as endocrine-disrupting chemicals (EDCs). These effects can take place right before puberty as well as much earlier, during fetal and neonatal life. Finally, environmental factors can interact with genetic factors in determining changes in pubertal timing. Therefore, the variance in pubertal timing is no longer to be considered under absolutely separate control by environmental and genetic determinants. Some recommendations are provided for evaluation of EDC impact in the management of pubertal disorders and for possible reduction of EDC exposure along the precautionary principle.

    Hormone replacement therapy (HRT) may reduce lung cancer risk. Dietary boron may have actions similar to those of HRT; however, no previous study has reported the associations between dietary boron intake and lung cancer risk or the joint effects of boron intake and HRT use on lung cancer risk. The authors examined the associations between boron intake and the joint effects of boron intake and HRT on lung cancer risk in women. In an ongoing case-control study in Houston, Texas (July 1995 through April 2005, end date for this analysis), 763 women were diagnosed with lung cancer, and 838 were matched healthy controls with data on both diet and HRT. Multiple logistic regression analyses were conducted to assess the associations between dietary boron and HRT with lung cancer risk. After adjustment for potential confounders, the odds ratios for lung cancer with decreasing quartiles of dietary boron intake were 1.0, 1.39 (95% confidence interval (CI): 1.02, 1.90), 1.64 (95% CI: 1.20, 2.24), and 1.95 (95% CI: 1.42, 2.68) mg/day, respectively, for all women (ptrend boron intake who used HRT, the odds ratio for lung cancer for low dietary boron intake and no HRT use was 2.07 (95% CI: 1.53, 2.81). Boron intake was inversely associated with lung cancer in women, whereas women who consumed low boron and did not use HRT were at substantial increased odds. PMID:18343880

    Relativistic models for finite nuclei contain spurious center-of-mass motion in most applications for the nuclear many-body problem, where the nuclear wave function is taken as a single Slater determinant within a space-fixed frame description. We use the Peierls-Yoccoz projection method, previously developed for relativistic approaches together with a reparametrization of the coupling constants that fits binding energies and charge radius and apply our results to calculate elastic electron scattering monopole charge form factors for light nuclei.

    In patients with chronic hepatitis C (CHC), obesity is involved in the pathogenesis of insulin resistance, fatty liver disease and progression of fibrosis. The objective of this study was to compare a normoglucidic low-calorie diet (NGLCD) with a low-fat diet (LFD) among participants with CHC. Aimed to measure the impact of dietary changes in reduction of insulin resistance, obesity but also in steatosis and fibrosis. Randomized, controlled trial in three medical centers with assessments at baseline, 6 months and 12 months. Participants were patients over 35 years with chronic hepatitis C (n = 120) with BMI over 25 kg/m². We evaluated the effects of NGLCD vs. LFD in weight management and metabolic improvement. The primary endpoint was to measure the impact of dietary changes through nutritional intervention in reversibility of insulin resistance, obesity, steatosis, and fibrosis. We performed anthropometric measurements, fasting glucose profile, serum lipids, liver profile, blood count at baseline, 6 and 12 months. Steatosis was evaluated using ultrasonographic criteria. Liver fibrosis was non-invasively assessed. After 6 and 12 months of intervention, both groups had a significant decrease in caloric consumption. At 6 months, weight loss was greater in the NGLCD group (-5.02 ± 3.43 kg vs. -4.1 ± 2.6 kg; p = 0.002) compared to the LFD group. At 1-year, however, weight loss was similar in both groups (-3.9 ± 3.3 kg vs. -3.1 ± 2.6 kg; p = 0.139). At 12 months, fasting plasma glucose, fasting plasma insulin, and HOMA-IR had significant improvements in both groups. With both diets aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyl transpeptidase (GGT) decreased with significant differences; also there were significant improvements in AST/ALT ratio, Forns fibrosis index. The two diets were associated with reduction of both the prevalence and the severity of steatosis (all p lifestyle intervention (specific

    Full Text Available Problem statement. For planning and organization of urban construction is necessary to analyze the use of areas. Territorial resources of the city, being used for construction and other urban purposes, consists of plots of land: disposable, reserved and undeveloped in previous years of construction in progress; residential districts and blocks of obsolete housing fund; industrial and municipal and warehouse enterprises being used irrationally or stopped to work; the defence department, where the amortized warehouses and other main funds are that are not used by purpose; agricultural enterprises where the obsolete industrial funds, haying, nurseries, greenhouses. The number of free areas suitable for future urban development is extremely limited. However a considerable part of the territories of almost all functional zones is used inefficiently. Purpose. Formalization of a factor of investment attractiveness of territories for the further identification and research of the connection between it and the cost of housing construction is necessary. Conclusion. The identification of regularities of influence of the factor of investment attractiveness of territories on the cost of construction of high-rise buildings allow to obtain a quantitative estimate of this effect and can be used in the development of the methodology of substantiation of the expediency and effectiveness of the implementation of highrise construction projects, based on organizational and technological aspects.

    This study investigated the determinants of overweight/obesity in adolescents. A cross-sectional survey was carried out on 1157 adolescents. Weight and height were measured. Information on socio-economic status (SES), dietary intakes, physical activity, and sedentary behaviours were collected by a self-administered questionnaire. Binary and multivariate binary logistic regressions were used to obtain the relationships and odds-ratios, respectively. The prevalence of overweight and obesity was higher among adolescents in low- or high-income families, adolescents whose mothers worked out of home, adolescents whose parents were both overweight, adolescents who watched a lot of TV or had excessive energy intake, adolescents with lower physical activity or lower intake of dietary fibre, those who skipped breakfast ≥ 4 times per week, and those with low and high fat intake. However, multiple logistic regression analysis showed that only energy intake was associated with increased odds and vegetables and fibre intake were associated with a reduction in the odds of being overweight (all poverweight/obesity than low and high SES due to better dietary intakes and less sedentary behaviours. Therefore, in overweight/obesity prevention programs, adolescents with determined risk factors from families with low and high SES should receive attention.

    This article reviews our current understanding on how xenobiotic metabolism and carcinogenesis are influenced by dietary and other factors. A major contributor to this research area was Dr. Allan Conney, and his contributions are highlighted. His studies on the induction of microsomal xenobiotic-metabolizing enzymes led to the characterization of the cytochrome P450 enzymes, which catalyze the metabolism of drugs, endogenous substrates, carcinogens and many other xenobiotics. These processes are influenced by drugs, diet, and other environmental factors. These studies provided the molecular basis for drug-drug, diet-drug, and herb-drug interactions. The elucidation of the metabolic activation of chemicals to their ultimate carcinogenic forms enables us to understand the molecular basis of chemical carcinogenesis. These studies led to many subsequent investigations on dietary approaches for cancer chemoprevention, including blocking of carcinogen activation, enhancing carcinogen detoxification, and influencing oncogenic pathways, which were carried out by Dr. Conney and others. The strengths and potential for practical application of these approaches are assessed herein.

    There is a paucity of data reflecting the symptomatic responses to dietary gluten (SRDG) in patients with Coeliac Disease (CD). We aimed to determine the type, timing and severity of SRDG with reference to a range of disease-related factors. Postal survey of 224 biopsy-proven patients including gluten-free diet (GFD) adherence, symptom checklist, ROME II criteria and The Hospital Anxiety & Depression Scale. Case-note review was also conducted. 26% of respondents were male. Full GFD adherence: n=159 (70%). Irritable bowel syndrome (IBS): n=50 (22%). Anxiety: n=30 (13%); Depression: n=33 (14%); Anxiety & Depression: n=72 (32%). Pruritus, fatigue and bloating were a more common SRDG in the partial/none GFD adherent group (p=ns). Co-existing IBS was associated with a greater prevalence of nausea and fatigue in response to gluten (p=gluten in the fully GFD adherent group is more likely to result in a severe SRDG in comparison to symptoms arising prior to consistent GFD adherence (OR 2.3; p=0.01). IBS sufferers are also more likely to rate their SRDG as severe in nature (OR 1.4; p=0.038). Patients with consistent GFD adherence experience a SRDG faster and more severe in comparison to prior gluten exposure possibly demonstrating an adept immunological response. Anxiety and depression also enhance the speed of symptom onset and co-existing visceral hypersensitivity is a risk factor for severe reactions to dietary gluten.

    Metabolic syndrome (MetS) is a health problem throughout the world and is associated with cardiovascular disease and diabetes. Thus, the purpose of the present work was to evaluate the effects of a dietary pattern (DP; soy protein, nopal, chia seed, and oat) on the biochemical variables of MetS, the AUC for glucose and insulin, glucose intolerance (GI), the relationship of the presence of certain polymorphisms related to MetS, and the response to the DP. In this randomized trial, the participants consumed their habitual diet but reduced by 500 kcal for 2 wk. They were then assigned to the placebo (P; n = 35) or DP (n = 32) group and consumed the reduced energy diet plus the P or DP beverage (235 kcal) minus the energy provided by these for 2 mo. All participants had decreases in body weight (BW), BMI, and waist circumference during the 2-mo treatment (P < 0.0001); however, only the DP group had decreases in serum TG, C-reactive protein (CRP), and AUC for insulin and GI after a glucose tolerance test. Interestingly, participants in the DP group with MetS and the ABCA1 R230C variant had a greater decrease in BW and an increase in serum adiponectin concentration after 2 mo of dietary treatment than those with the ABCA1 R230R variant. The results from this study suggest that lifestyle interventions involving specific DP for the treatment of MetS could be more effective if local foods and genetic variations of the population are considered.

It mostly affects the adult population but children and adolescent are also prone to develop obesity. the present study was undertaken among school children with the objective of finding out the relative proportion of underweight and overweight among study subjects on the basis of BMI and influence of some selected dietary factors on BMI status. Methods: The cross sectional study was done in 4 public schools located in Guntur city selected by random selecting technique using purposive sampling procedure keeping in view the operational feasibility. Total 570 male students in the age group of 13-15 were included in the study .The study was conducted during 0ctober and November 2008. Results: The proportion of overweight (13.86% among study subjects was more than underweight (11.93%. The daily consumption rates of different energy dense foods found to vary from 17.54 % for butter to 25.44% for fast food while the rate of daily and week The practices of eating until plate is finished and eating more fried food showed wide variation among different BMI categories. The difference were statistically highly significant. The rate of daily and weekly consumption together varied between 59.65% for butter and 67.72 % for sweets. Conclusion: The result of the present study shows that the diet habit like eating sweets and eating behaviour like snacking and eating more fried food were significantly associated with high prevalence of overweight among school children. So nutrition education should be given in schools regarding this to prevent occurrence of life style diseases in future [Natl J Med Res 2013; 3(2.000: 156-158

    AIM: To systematically examine the extent of correlation of risk factors, such as age, consumed dietary habit and familial predisposition with somatic Tp53 molecular lesion causal to elevate carcinogenesis severity of esophageal squamous cell carcinoma (ESCC) among the Kashmiri population of Northern India.METHODS: All cases (n = 51) and controls (n = 150) were permanent residents of the Kashmir valley. Genetic alterations were determined in exons 5-8 of Tp53 tumor suppressor gene among 45 ESCC cases histologically confirmed by PCR-SSCP analysis. Data for individual cancer cases (n = 45) and inpatient controls (n = 150) with non-cancer disease included information on family history of cancer, thirty prevailing common dietary risk factors along with patient's age group. Correlation of genetic lesion in p53 exons to animistic data from these parameters was generated by Chi-square test to all 45 histologically confirmed ESCC cases along with healthy controls.RESULTS: Thirty-five of 45 (77.8%) histologically characterized tumor samples had analogous somatic mutation as opposed to 1 of 45 normal sample obtained from adjacent region from the same patient showed germline mutation. The SSCP analysis demonstrated that most common p53 gene alterations were found in exon 6 (77.7%), that did not correlate with the age of the individual and clinicopathological parameters but showed significant concordance (P < 0.05) with familial history of cancer (CD = 58), suggesting germline predisposition at an unknown locus, and dietary habit of consuming locally grown Brassica vegetable "Hakh" (CD = 19.5),red chillies (CD = 20.2), hot salty soda tea (CD = 2.37) and local baked bread (CD = 1.1).CONCLUSION: Our study suggests that somatic chromosomal mutations, especially in exon 6 of Tp53 gene, among esophageal cancer patients of an ethnically homogenous population of Kashmir valley are closely related to continued exposure to various common dietary risk factors, especially hot salty tea

    Full Text Available Health inequalities: differences in health status or in the distribution of health determinants between different population groups. Some health inequalities are attributable to biological variations or free choice and others are attributable to the external environment and conditions mainly outside the control of the individuals concerned. 347 million people worldwide have diabetes. In 2012 an estimated 1.5 million deaths were directly caused by diabetes. More than 80% of diabetes deaths occur in low- and middle-income countries. WHO projects that diabetes will be the 7th leading cause of death in 2030. Healthy diet, regular physical activity and maintaining a normal body weight can prevent or delay the onset of type 2 diabetes. Risk factors: 1. Age- the prevalence of diabetes rises steeply with age: *one in twenty people over the age of 65 have diabetes, *and this rises to one in five people over the age of 85 years. The diagnosis of diabetes may be delayed in older people, with symptoms of diabetes being wrongly attributed to ageing. 2. Ethnic: type 2 diabetes is up to six times more common in people of South Asian descent and up to three times more common in those of African and African-Caribbean descent then in the white population. It is also more common in people of Chinese descent and other non-Caucasian groups. 3. Gender: the frequency of diabetes usually is higher in men than in women. This may be because gender compounds other aspects of inequality- women often bear the brunt of poverty, and socio-economic differences in the prevalence of diabetes are more marked for women, probably because of differences in smoking rates, food choices and the prevalence of obesity. 4. Overweight/Obesity: every 1 kg/m2 more causes increase risk: cardiovascular diseases 2%, coronary artery disease- 3% , myocardial infarction- 5% , heart failure- 5% , peripheral vascular disease- 5%.

    This study examined the influence of food consumption diversity on adequate intakes of food calories, proteins and micronutrients among households in rural Nigeria within the framework of panel data econometrics using a nationally representative data. We found that substantial proportion of households suffered deficiency of calories, proteins and certain micronutrients; with higher percentage of sufferer households occurring in the post-planting season. The different measures of dietary diversity (constructed and used for analysis) consistently indicate significant and positive influence of dietary diversity on the likelihood of adequate consumption of food nutrients. While higher level of income, education and non-farm enterprise engagement may strongly stimulate adequate nutrient intakes, increases in the number of adolescents would substantially diminish it. Although our findings call for renewed attention on diet diverseness, we stress the complementary/synergistic roles of education and rural income improvement, especially through non-farm enterprise diversification in tackling multiple nutritional deficiencies in rural Nigeria.

FTO-rs9939609 is associated with BMI and WC at baseline, but association with weight gain is weak......Although FTO is an established obesity-susceptibility locus, it remains unknown whether it influences weight change in adult life and whether diet attenuates this association. Therefore, we investigated the association of FTO-rs9939609 with changes in weight and waist circumference (WC) during 6.......8 years follow-up in a large-scale prospective study and examined whether these associations were modified by dietary energy percentage from fat, protein, carbohydrate, or glycemic index (GI). This study comprised data from five countries of European Prospective Investigation into Cancer and Nutrition...

    Intestinal homeostasis is precisely regulated by a number of endogenous regulatory molecules but significantly influenced by dietary compounds. Malfunction of this system may result in chronic inflammation and cancer. Dietary essential n-3 polyunsaturated fatty acids (PUFAs) and short-chain fatty acid butyrate produced from fibre display anti-inflammatory and anticancer activities. Both compounds were shown to modulate the production and activities of TNF family cytokines. Cytokines from the TNF family (TNF- α, TRAIL, and FasL) have potent inflammatory activities and can also regulate apoptosis, which plays an important role in cancer development. The results of our own research showed enhancement of apoptosis in colon cancer cells by a combination of either docosahexaenoic acid (DHA) or butyrate with TNF family cytokines, especially by promotion of the mitochondrial apoptotic pathway and modulation of NF κ B activity. This review is focused mainly on the interaction of dietary PUFAs and butyrate with these cytokines during colon inflammation and cancer development. We summarised recent knowledge about the cellular and molecular mechanisms involved in such effects and outcomes for intestinal cell behaviour and pathologies. Finally, the possible application for the prevention and therapy of colon inflammation and cancer is also outlined.

    In a population-based case-control study of 416 incident gliomas in adults carried out in Melbourne, Australia, between 1987 and 1991, 409 age-sex-matched case-control pairs (243 male and 166 female) had adequate data available to examine associations between the dietary intake of N-nitroso compounds, N-nitroso precursors, other nutrients including N-nitroso inhibitors, and the risk of glioma. Dietary intakes were based on the reported frequency of consumption of 59 food items. Increased odds ratio (OR) were observed in males who consumed high levels of bacon, corned meats, apples, melons and oil. OR less than unity were observed in men consuming cabbage and cola drinks, and in women who consumed wholegrain bread, pasta, corned meat, bananas, cauliflower, brocoli, cola drinks and nuts. Generally, N-nitroso associations were greater in men and micronutrient associations were greater in women. Elevated OR in men, but not women, were associated with the intake of N-nitroso dimethylamine (NDMA), retinol and vitamin E. The intake of nitrate (largely of vegetable origin) was protective in women but not in men. When analyzed using multiple logistic regression, the association with NDMA intake in males was not modified by dietary micronutrient intakes. In females, beta carotene alone, though not directly associated with risk, modified the effect of NDMA. On balance, this study added only limited support to the N-nitroso hypothesis of glial carcinogenesis.

    The aim of this study was to investigate the prevalence of obesity, dietary habits, and sedentary patterns among Sudanese adolescents. A multistage stratified sampling method was used to select 945 adolescents (507 males and 438 females) aged 14 to 18 years, from Khartoum State, Sudan. A self-reported pretested questionnaire was used to collect the data. Overweight and obesity were determined using the International Obesity Task Force standard, which is based on body mass index for sex and age. Overweight and obesity were growing problems among urban Sudanese adolescents (10.7%). Breakfast was commonly consumed on a daily basis by the majority of adolescents (74.2%), followed by lunch (63.9%) and supper (33.5%). Snacking was not a common practice among these individuals. Vegetables (63.9%) were more frequently consumed (more than 3 days per week) than fruit (30.1%). There were significant differences between genders regarding intake of vegetables (P risk factors for diet-related chronic diseases such as unhealthy dietary habits and sedentary behaviors are starting to rise among urban adolescents in Sudan. This creates the need for immediate action to prevent and control these risk factors before these diseases become major public health problems. © The Author(s) 2016.

    The Dietary Approach to Stop Hypertension (DASH) is recommended to lower blood pressure (BP), but its effects on cardiometabolic biomarkers are unclear. A systematic review and meta-analysis of randomised controlled trials (RCT) was conducted to determine the effects of the DASH diet on cardiovascular risk factors. Medline, Embase and Scopus databases were searched from inception to December 2013. Inclusion criteria were as follows: (1) DASH diet; (2) RCT; (3) risk factors including systolic and diastolic BP and glucose, HDL, LDL, TAG and total cholesterol concentrations; (4) control group. Random-effects models were used to determine the pooled effect sizes. Meta-regression analyses were carried out to examine the association between effect sizes, baseline values of the risk factors, BMI, age, quality of trials, salt intake and study duration. A total of twenty articles reporting data for 1917 participants were included in the meta-analysis. The duration of interventions ranged from 2 to 24 weeks. The DASH diet was found to result in significant decreases in systolic BP ( - 5·2 mmHg, 95% CI - 7·0, - 3·4; PFramingham risk score for CVD. The DASH diet improved cardiovascular risk factors and appeared to have greater beneficial effects in subjects with an increased cardiometabolic risk. The DASH diet is an effective nutritional strategy to prevent CVD.

    We examined the determinants of dietary vitamin A intake among Sudanese children, information which is important for designing effective interventions based on the dietary approach. Children under the age of two years were at greater risk of consuming a diet low in vitamin A compared with children who were five years or older. Compared with children from relatively affluent households, those from poorer households were about twice as likely to consume low levels of carotenoid or preformed vitamin A. Low vitamin A intake was also significantly associated with lack of running water, a latrine, radio, or television in the household, and inversely associated with maternal or paternal illiteracy and with cleanliness of the child subjectively assessed by the interviewer. As expected, breastfed children in the first two years of life were likely to consume lower levels of preformed vitamin A and carotenoid from food (excluding breast milk) compared with non-breastfed children. Low vitamin A intake was more prevalent in the dry months of the year. Efforts to increase accessibility to vitamin A containing food, combined with nutrition education campaigns and public health programmes directed at improving sanitation and reducing infection are necessary as part of the long-term solution to the problem of vitamin A deficiency.

    To analyze dietary patterns of infants and its association with maternal socioeconomic, cultural, and demographic variables. A cross-sectional study was conducted with two groups of mothers of children up to 24 months (n=202) living in the city of Maceió, Alagoas, Northeast Brazil. The case group consisted of mothers enrolled in a Family Health Unit. The comparison group consisted of mothers who took their children to two private pediatric offices of the city. Dietary intake was assessed using a qualitative and validated food frequency questionnaire (FFQ). The evaluation of the FFQ was performed by a method in which the overall rate of consumption frequency is converted into a score. Children of higher income families and mothers with better education level (control group) showed the highest median of consumption scores for fruits and vegetables (p<0.01) and meat, offal, and eggs (p<0.01), when compared with children of the case group. On the other hand, the median of consumption scores of manufactured goods was higher among children in the case group (p<0.01). Maternal socioeconomic status influenced the quality of food offered to the infant. In the case group, children up to 24 months already consumed industrial products instead of healthy foods on their menu. Copyright © 2015 Sociedade de Pediatria de São Paulo.

    We examined familial bone mineral density (BMD) interactions between parents and children and lifestyle factors affecting BMD in the Korean general population of children under 20 and parents under 50 years of age. This cross-sectional study included 2,453 participants (667 daughters, 705 sons, 719 mothers, and 362 fathers) in the 2009-2010 Korean National Health and Nutrition Examination Survey. We calculated prevalence ratios and 95 % confidence intervals for BMD values of whole femur, femur neck, lumbar spine, and whole body excluding the head being in the low tertile in adolescents according to parental BMD tertile after adjusting for physical, lifestyle, and dietary factors. For daughters and sons, there were significant differences in BMD at the four bone sites according to age group, body fat percentage, regular walking and exercise, and milk consumption compared to the reference value for each classification category. Surprisingly, there were no differences in BMD according to serum 25-OH-D levels. Birth order affected BMD of only whole body except head, but its impact was less than that of lifestyle factors. The mean differences in BMD between daughters and sons in the first and third parental BMD tertiles were statistically significant. Notably, the prevalence ratio of whole body without head BMD being in the low tertile increased eight and ten-folds in adolescent daughters and sons, respectively, when parents were in the low BMD tertile. In specific bone regions, parental BMD had a greater effect on total femur in daughters but in the lumbar spine in sons. In conclusion, parental BMD positively influences BMD in daughters and sons after adjustment for environmental parameters. This suggests that the children from parents with low BMD need to make an extra effort to increase BMD through dietary and lifestyle changes.

    Exposome-Explorer (http://exposome-explorer.iarc.fr) is the first database dedicated to biomarkers of exposure to environmental risk factors. It contains detailed information on the nature of biomarkers, their concentrations in various human biospecimens, the study population where measured and the analytical techniques used for measurement. It also contains correlations with external exposure measurements and data on biological reproducibility over time. The data in Exposome-Explorer was manually collected from peer-reviewed publications and organized to make it easily accessible through a web interface for in-depth analyses. The database and the web interface were developed using the Ruby on Rails framework. A total of 480 publications were analyzed and 10 510 concentration values in blood, urine and other biospecimens for 692 dietary and pollutant biomarkers were collected. Over 8000 correlation values between dietary biomarker levels and food intake as well as 536 values of biological reproducibility over time were also compiled. Exposome-Explorer makes it easy to compare the performance between biomarkers and their fields of application. It should be particularly useful for epidemiologists and clinicians wishing to select panels of biomarkers that can be used in biomonitoring studies or in exposome-wide association studies, thereby allowing them to better understand the etiology of chronic diseases.

    Study was undertaken to know food and nutrient consumption patterns and their relationship with nutritional status among rural adolescents in Orissa. It was a Community based cross sectional study, conducted at district level in the State of Orissa. Data on 686 adolescent boys and 689 adolescent girls were utilized. Factor analysis was used to find dietary pattern and discriminate analysis and its relationship with undernutrition. The study revealed that among adolescent boys, there existed six patterns among food-groups and three patterns among nutrients explaining 52% and 76% of total variation. Similarly among adolescent girls, seven patterns among food groups and three patterns among nutrients, explaining 67% and 80% of total variation. The discriminate analysis using the factor scores revealed overall 56% of adolescent boys, and 53% of girls were correctly classified. About 46% of boys who were actually thin were predicted as normal, while, 40% who were normal were predicted as thin. Among girls 50% who were actually thin were predicted as normal, while, 36% who were normal were predicted as thin. In conclusions, there exists considerable relationship between dietary patterns and nutritional status among rural adolescents.

    This study was conducted to determine the effects of graded doses of L-glutamine supplementation on the replication and distribution of Pasteurella multocida, and the expression of its major virulence factors in mouse model. Mice were randomly assigned to the basal diet supplemented with 0, 0.5, 1.0 or 2.0 % glutamine. Pasteurella multocida burden was detected in the heart, liver, spleen, lung and kidney after 12 h of P. multocida infection. The expression of major virulence factors, toll-like receptors (TLRs), proinflammatory cytokines (interleukin-1 beta, interleukin-6, and tumor necrosis factor alpha) and anti-oxidative factors (GPX1 and CuZnSOD) was analyzed in the lung and spleen. Dietary 0.5 % glutamine supplementation has little significant effect on these parameters, compared to those with basal diet. However, results showed that a high dose of glutamine supplementation increased the P. multocida burden (P glutamine supplementation inhibited the proinflammatory responses (P glutamine supplementation on different components in TLR signaling depends on glutamine concentration, and high dose of glutamine supplementation activated the proinflammatory response. In conclusion, glutamine supplementation increased P. multocida burden and the expression of its major virulence factors, while affecting the functions of the lung and spleen.

    To determine the prevalence of mild and excessive somnolence and the associated factors with the presence of daytime sleepiness in the elderly. A total of 1780 independent individuals 60 years and older of both sexes (70.9±7.9 years old; females 62%), were included, of which 1704 of them completed all the information. All of them were assessed using an Epworth sleepiness scale (ESE), an Pittsburgh sleep quality index, plus information of cigarettes smoking, dinner time, and an anthropometric evaluation. An ESE score>10 was considered drowsiness and scores>15 excessive or severe drowsiness. Among the population under 80 years, 5.3% showed ESE score>15 and 26.2% an ESE score>10. For over 80 years, the prevalence of sleepiness was 6.3% for an ESE score>15 and 32.5% for an ESE score>10. In the adjusted model, the factors associated with increased risk of sleepiness (ESE>10) were age older than 80 years (OR=1.58; 95% CI=1.14 to 2.19) and dinner after 21 hours (OR=1.3; 95% CI=1.01 to 1.68). By contrast, only age older than 80 years was independently associated with severe sleepiness (OR=1.81; 95% CI=1.01 to 3.29). Meals after 21 hours and age above 80 years are associated with increased likelihood of daytime sleepiness. Instead, only older than 80 years is associated with severe daytime sleepiness.

    We provide an overview of the role of adiposity, physical activity and diet in the risk for breast cancer in Mexican women. Lack of physical activity, diets high in carbohydrates and in glycemic load and low intake of folate and vitamin B12 have been shown to increase the risk of breast cancer in Mexican women, in particular postmenopausal breast cancer. Other dietary factors that may begin to play a more relevant role in breast cancer incidence in Mexico are alcohol intake and vitamin D status. Recommendations to maintain a healthy weight, practice moderate physical activity, decrease intake of rapidly absorbed carbohydrates and increase consumption of fruits and vegetables could have an important impact on the epidemic of breast cancer in Mexico.

    In rural Xuanwei County, China, the high incidence of lung cancer is attributable largely to burning smoky coal indoors for heating and cooking without adequate ventilation. Such burning generates very high levels of indoor air pollutants, including carcinogenic polycyclic aromatic hydrocarbons, which could contaminate foodstuffs in the home. Thus, residents could be exposed to carcinogenic coal emissions not only via inhalation but also via ingestion of these foodstuffs. A population-based case-control study of 498 lung cancer patients and 498 controls was conducted from 1985 through 1990 in Xuanwei. The interviewer-administered study questionnaire queried the frequency of food items commonly consumed in this region. Overall and sex-specific multiple logistic regression models were constructed to estimate odds ratios (OR) and 95% confidence intervals (CI) for consumption of these foods. Intake of rice, green vegetables, mushrooms and fresh meat was associated with an increased risk of lung cancer. In contrast, intake of corn, buckwheat, radishes, peppers, melons, pickled vegetables, and salt-preserved meats was associated with reduced risk. The detrimental. effect of ingesting green vegetables (OR, 2.39; 95% CI, 1.28-4.48) is consistent with previous reports. These findings suggest that in Xuanwei, food contamination by environmental polycyclic aromatic hydrocarbons may be an important risk factor for lung cancer, and that differential contamination of foods by polycyclic aromatic hydrocarbons possibly explained the different associations with lung cancer risk.

    Full Text Available Abstract This study observed the effect of a dietary re-education plus regular physical activity on body composition, risk factors and physical test performance of sedentary overweight/obese women and to correlate these variables one with each other. Fifty women (36 ± 10 yrs; 31 ± 6 body mass index (BMI, kg/m2 volunteered for the study. Body compositions were obtained by anthropometry and bioimpedance and some body indexes were established. One-repetition maximum (1-RM and treadmill VO2max tests were carried out and blood samples were obtained for lipid, glucose and uric acid analyses before (T1 and after two months of intervention (T2. Diet was established by indirect calorimetry. Body fat, glucose, uric acid, total cholesterol, HDL-cholesterol and systolic blood pressure were significantly reduced. The 1-RM and VO2max tests were significantly increased. Neck circumference (NC was correlated with body composition, back muscle 1-MR, HDL and LDL cholesterol, total cholesterol/HDL ratio, uric acid, and resting energy expenditure. BMI was found to be significantly correlated with waist/hip ratio, circumference sum, and body fat percentage by anthropometry and bioimpedance. Body fat percentage determined by bioimpedance and anthropometry was significantly correlated with arm fat area and arm fat area corrected respectively, and both with BMI at T1 and T2. This study suggests that a dietary reeducation plus physical activity around 200 min/week improved body composition and the health of these women. Many anthropometry measurements have correspondence to risk factors and NC could be a simple approach to reflect these results, without other more complex techniques.

    Full Text Available Introduction: Colorectal cancer is the most common tumor in the developed countries, and the number of new cases annualy is aproximately equal for men and women. Several environmental factors can interact in all steps of carcinogenesis. Lately the balance between genetic predisposition and these factors, including nutritional components and lifestyle behaviors, determines individual susceptibility to develop colorectal cancer. The aim of this study is to revise the references about lifestyle include diet, physical exercise, tobacco smoking and use of alcohol, and the risk of colorectal cancer in databases published during 1994-2004. Dietary factors: According to the reports high intake of red meat, and particularly of processed meat and positive energetic balance (high intake of total fat and carbohydrate was associated with a moderate but significant increase in colorectal cancer risk. Convincing preventive factors include increase consumption of a wide variety of fruit and vegetable, particularly, dark-green leafy, cruciferous, a deep-yellow on tones, and fibre. Lifestyle: Physical activity as a means for the primary prevention of colorectal cancer. There is a probable synergic effect among physical inactivity, high energy intake and obesity and incidence of colorectal cancer. A growing body of evidence supports that avoidance overweight and the use of tobacco and alcohol is recommended to prevent colorectal cancer. Conclusion: Current data suggest that lifestyle modification including proper diet such as the ones rich in vegetable and poor in red meat and fat, regular physical activity and maintaining an appropriate body weight and avoiding the use of tobacco and alcohol may lead to reduce colorectal cancer risk.Introducción: el cáncer colorrectal es el tumor más frecuente de los países desarrollados, y el número anual de casos nuevos es aproximadamente igual en hombres que en mujeres.

    Full Text Available Background: Obesity has reached epidemic proportions globally and is a major contributor to the global burden of chronic diseases. Dietary factors are the major modifiable factors through which many of the external forces promoting weight gain act. Objectives: The objectives were to find the prevalence of overweight and obesity in the urban population of Jamnagar and to explore the effect of dietary factors on the weight status of the people. Materials and Methods: A cross-sectional study was conducted among the adult population of Jamnagar city. Cluster sampling technique was used to select study samples. Data were collected in a prestructured questionnaire by interviewing subjects through house-to-house visits. Data were analyzed in Epi Info and appropriate statistical methods were used. Results: The prevalence of overweight and obesity was found to be 22.04% and 5.20%, respectively. Overweight was more prevalent in females than males. The prevalence rose with an increase in age up to 60 years. Among dietary factors, the total calorie intake and habit of snacking had a positive association with weight gain (P < 0.05. The mean intake of oil was more and the mean intake of vegetables was less among overweight subjects than nonoverweight subjects (P < 0.05. Conclusion: The prevalence of overweight and obesity in the urban population in Jamnagar was found to be 22.04% and 5.20%, respectively. Total calorie intake as well as composition of diet was the important dietary factor affecting weight gain.

    Purpose: To study the impact of clinical predisposing factors on rectal normal tissue complication probability modeling using the updated results of the Dutch prostate dose-escalation trial. Methods and Materials: Toxicity data of 512 patients (conformally treated to 68 Gy [n = 284] and 78 Gy [n = 228]) with complete follow-up at 3 years after radiotherapy were studied. Scored end points were rectal bleeding, high stool frequency, and fecal incontinence. Two traditional dose-based models (Lyman-Kutcher-Burman (LKB) and Relative Seriality (RS) and a logistic model were fitted using a maximum likelihood approach. Furthermore, these model fits were improved by including the most significant clinical factors. The area under the receiver operating characteristic curve (AUC) was used to compare the discriminating ability of all fits. Results: Including clinical factors significantly increased the predictive power of the models for all end points. In the optimal LKB, RS, and logistic models for rectal bleeding and fecal incontinence, the first significant (p = 0.011-0.013) clinical factor was 'previous abdominal surgery.' As second significant (p = 0.012-0.016) factor, 'cardiac history' was included in all three rectal bleeding fits, whereas including 'diabetes' was significant (p = 0.039-0.048) in fecal incontinence modeling but only in the LKB and logistic models. High stool frequency fits only benefitted significantly (p = 0.003-0.006) from the inclusion of the baseline toxicity score. For all models rectal bleeding fits had the highest AUC (0.77) where it was 0.63 and 0.68 for high stool frequency and fecal incontinence, respectively. LKB and logistic model fits resulted in similar values for the volume parameter. The steepness parameter was somewhat higher in the logistic model, also resulting in a slightly lower D{sub 50}. Anal wall DVHs were used for fecal incontinence, whereas anorectal wall dose best described the other two endpoints

    The anatomical location of the central nervous system (CNS) renders it immunologically and pharmacologically privileged due to the blood brain barrier (BBB). Although this limits the transport of unfavorable molecules to the CNS, the ensuing privilege could be disadvantageous for therapeutic compounds. Hence, the greatest challenge in the pharmacotherapy of CNS diseases is to ensure efficient brain targeting and drug delivery. Research evidences indicate that dietary polyphenols have neuroprotective potential against CNS diseases. However, their selective permeability across BBB, poor absorption, rapid metabolism and systemic elimination limit their bioavailability and therapeutic efficacy. Consequently, the beneficial effects of these orally administered agents in the CNS still remain a subject of debate. This has also limited its clinical application either as independent or adjunctive therapy. Improving the in vivo bioavailability by novel methods could improve the therapeutic feasibility of polyphenols and assist in evolving novel drugs and their derivatives with improved efficacy in vivo. Here we review the mechanistic and pharmacological issues related to the bioavailability of polyphenols with therapeutic implications for CNS diseases. We surmise that improving the bioavailability of polyphenols entails efficient in vivo transport across BBB, biochemical stability, improved half-life and persistent neuroprotection in the CNS.

    Ayurveda claims to be effective in the treatment of psychosomatic disorders by means of lifestyle and nutritional counseling. In a randomized controlled study mothers with burnout were randomized into two groups: Ayurvedic nutritional counseling (according to tradition), and conventional nutritional counseling (following the recommendations of a family doctor). Patients received five counseling sessions over twelve weeks. Outcomes included levels of burnout, quality of life, sleep, stress, depression/anxiety, and spirituality at three and six months. It also included a qualitative evaluation of the communication processes. We randomized thirty four patients; twenty three participants were included in the per protocol analysis. No significant differences were observed between the groups. However, significant and clinically relevant intra-group mean changes for the primary outcome burnout, and secondary outcomes sleep, stress, depression and mental health were only found in the Ayurveda group. The qualitative part of the study identified different conversational styles and counseling techniques between the two study groups. In conventional consultations questions tended to be category bound, while counseling-advice was predominantly admonitory. The Ayurvedic practitioner used open-ended interrogative forms, devices for displaying understanding, and positive re-evaluation more frequently, leading to an overall less asymmetrical interaction. We found positive effects for both groups, which however were more pronounced in the Ayurvedic group. The conversational and counseling techniques in the Ayurvedic group offered more opportunities for problem description by patients as well as patient-centered practice and resource-oriented recommendations by the physician.

    The aim of the current study was to investigate the relationship between dietary intake, type of feeding during infancy, other lifestyle and sociodemographic factors, and dental caries. A cross-sectional study. The study was carried out on children younger than 16 years of age who visited Primary Health Care Centers. The study was carried out over a period from October 2010 to June 2011 in Qatar. A random sample of 1752 children aged 6-15 years old who visited the Primary Health Care Centers was approached, and parents of 1284 children provided their consent and fulfilled the inclusion criteria (corresponding to a response rate of 73%). The study was based on a questionnaire that included variables such as sociodemographic information, lifestyle, family history, and feeding patterns during infancy, information on oral hygiene practices, and clinical examination. The status of dental caries was recorded on the basis of the WHO criteria. The prevalence of dental caries [decayed, missed, or filled tooth (DMFT)] in the permanent dentition among children was 73% [95% confidence interval (CI): 71-75%], with a mean DMFT value of 4.5 (SD: 4.2). The numbers of children consuming sea food, cod liver oil, and vitamin-D-fortified milk less than once a week were significantly higher in the dental caries group compared with those without caries (11.7 vs. 8.3%; P=0.05, 92.4 vs. 87.5%; P=0.005, and 10.6 vs. 6.3%; P=0.011, respectively). Multivariable logistic regression analysis showed that being female [adjusted odds ratio (OR): 1.41; 95% CI: 1.07-1.84], having a BMI greater than the 95th percentile versus less than the 85th percentile (adjusted OR: 2.12; 95% CI: 1.17-3.84), a monthly household income of at least 10 000 QAR (adjusted OR: 2.61; 95% CI: 1.69-4.02), consumption of cod liver oil less than once a week (adjusted OR: 2.13; 95% CI: 1.35-3.37), 1-year increase in age (adjusted OR: 1.05; 95% CI: 1.01-1.11), being formula fed during infancy (adjusted OR: 2.27; 95% CI: 1

    Dietary patterns analysis is an emerging area of research. Identifying distinct patterns within a large dietary survey can give a more accurate representation of what people are eating. Furthermore, it allows researchers to analyse relationships between non-communicable diseases (NCD) and complete diets rather than individual food items or nutrients. However, few such studies have been conducted in developing countries including India, where the population has a high burden of diabetes and CVD. We undertook a systematic review of published and grey literature exploring dietary patterns and relationships with diet-related NCD in India. We identified eight studies, including eleven separate models of dietary patterns. Most dietary patterns were vegetarian with a predominance of fruit, vegetables and pulses, as well as cereals; dietary patterns based on high-fat, high-sugar foods and more meat were also identified. There was large variability between regions in dietary patterns, and there was some evidence of change in diets over time, although no evidence of different diets by sex or age was found. Consumers of high-fat dietary patterns were more likely to have greater BMI, and a dietary pattern high in sweets and snacks was associated with greater risk of diabetes compared with a traditional diet high in rice and pulses, but other relationships with NCD risk factors were less clear. This review shows that dietary pattern analyses can be highly valuable in assessing variability in national diets and diet-disease relationships. However, to date, most studies in India are limited by data and methodological shortcomings.

    Gastrointestinal diseases pose significant risks to captive cheetah survival and welfare. Multiple factors are thought to be associated with these diseases, but to date a comprehensive epidemiological survey of disease risk factors has not been conducted. A survey of diet and health parameters was completed for 184 captive cheetahs in 86 international facilities. Comparisons were made among dietary factors with respect to disease status and observed faecal consistency, incidence of vomiting and diarrhoea in the past 4 weeks. Extremely dry faeces were most common in cheetahs fed carcasses, but was still of low incidence (15%). Contrastingly, cheetahs fed commercially prepared diets had the highest prevalence of liquid faeces "always" or "often" (9%). Cheetahs fed raw meat diets had the highest prevalence of soft faeces with no shape (22%), as well as of firm and dry faeces (40%). No broad category of diet exerted any influence on the health parameters investigated. However, feeding of ribs at least once per week reduced the odds of diarrhoea (P = 0.020) and feeding of long bones (limbs) at least once per week was associated with a lower odds of vomiting (P = 0.008). Cheetahs fed muscle meat at least once per week had reduced odds of suffering from chronic gastritis (P = 0.005) or non-specific gastrointestinal disease (P cheetahs, warrants caution until further research is conducted.

    Colostrum is the main external resource providing piglets with nutrients and maternal immune molecules. Astragalus polysaccharides (APS) have been used as immunopotentiators in vitro and several animal models. This study aimed to determine the effects of APS on immune factors in sow colostrum and milk. The sow diet was supplemented with APS one week before the expected delivery date. Colostrum and milk were collected and designated as 0 h- (onset of parturition), 12 h-, and 24 h-colostrum and 36 h-milk postpartum. Samples were measured using porcine immunoglobulin (Ig) G, IgM, classical swine fever virus antibody (CSFV Ab), epidermal growth factor (EGF), and insulin-like growth factor- (IGF-) 1 ELISA Quantitation Kits. Dietary supplementation of APS significantly enhanced the presence of IgG, IgM, EGF, and IGF-1 in 0 h-colostrum (P colostrum and/or milk; and status of some specific vaccination could be determined through using colostrum or early milk in sow.

    2004-05-01

    To reduce the incidence of dysentery, cholera and other water-borne diseases and mortality of people drinking from surface contaminated sources of water, the World Bank and United Nations Children's Fund began to sink tube wells into the underlying aquifers of Bangladesh and West Bengal, India, in the 1970s. Many of the tube wells were drilled into underground aquifers that provided microbiologically clean water that was later determined to contain arsenic (As). As contamination of drinking water is a problem of natural occurrence throughout the world and domestic water often exceeds the World Health Organization limit of 50 microg As/l in the countries of Bangladesh, West Bengal, India and Nepal as well as other areas occupying much of the Ganges-Brahmaputra delta. It is estimated that as many as one-half of these tube wells discharge water with sufficient amounts of As to produce arsenicosis, i.e. As toxicity in the human population. Access to clean As free water is the priority of most organized relief efforts. Where As free domestic water cannot be provided, an improved diet and/or dietary supplements may ameliorate As toxicity or prevent its toxicity all together. The dietary status of the essential human trace element, selenium (Se) may be adversely affected by a chronic excessive ingestion of As. As added to animal diets has been known to counteract Se toxicity in animals since the 1930s. It is reasoned therefore, that high levels of chronic As ingestion from well water by people within the delta will accelerate the excretion of Se lowering the body's content of this essential trace element. Excessive Se excretion owing to Se/As complexation may add to the likelihood of As being more toxic and carcinogenic over time, due to the oxidative stress imposed by the excessive As and low Se ingestion. Because of the unique environment of the Ganges-Brahmaputra delta in which millions of people are presently exposed to As, we ask the question: are low dietary Se

    Full Text Available Hypercholesterolemia which frequently follows renal transplantation, places kidney graft recipients at an increased risk for atherosclerosis and cardiovascular diseases. We attempt in this study to determine the prevalence, and evaluate severity and treatment of hypercholesterolemia in kidney transplant recipients. We studied 78 renal transplant patients with a mean age of 42.1 years and mean transplant duration of 6.2 years (range from six months to 8.5 years. They were on triple immunosuppressive therapy and had serum creatinine level of less than 160µmol/L. Thirty-one patients (39.8% were found to have blood cholesterol levels > 6.4 mmol/L. Significant positive correlation was found between hypercholesterolemia and cyclosporine blood levels above 200 ng/ml (p< 0.0009. Furthermore, proteinuria positively correlated with hypercholesterolemia (p< 0.0006. There was no significant correlation between cholesterol blood level and the patient age, sex, presence of diabetes, prednisolone, dose, or treatment with C.-blockers and diuretics. Dietary modification was not effective in reducing the blood cholesterol level in our patients, so we used fluvastatin in a dose of 20 to 40 mg daily for a period of three months. This drug was effective in lowering the mean cholesterol blood levels from 7.1 to 5.2 mmol/L (p< 0.005. One out of 19-electromyogram studies showed abnormal pattern. We did not notice change in the levels of creatinine phosphokinase, serum creatinine or lover enzymes. In conclusion, hyper-cholesterolemia is common in stable renal transplant patients. The presence of proteinuria and the high level of blood cyclosporine are significantly associated with hypercholesterolemia. Low-dose fluvastatin was well-tolerated and effective cholesterol lowering treatment.

    Bone marrow-derived mesenchymal stem cells (MSCs) have contributed to the improvement of diabetic nephropathy (DN); however, the actual mediator of this effect and its role has not been characterized thoroughly. We investigated the effects of MSC therapy on DN, focusing on the paracrine effect of renal trophic factors, including exosomes secreted by MSCs. MSCs and MSC-conditioned medium (MSC-CM) as renal trophic factors were administered in parallel to high-fat diet (HFD)-induced type 2 diabetic mice and streptozotocin (STZ)-induced insulin-deficient diabetic mice. Both therapies showed approximately equivalent curative effects, as each inhibited the exacerbation of albuminuria. They also suppressed the excessive infiltration of BMDCs into the kidney by regulating the expression of the adhesion molecule ICAM-1. Proinflammatory cytokine expression (e.g., TNF-α) and fibrosis in tubular interstitium were inhibited. TGF-β1 expression was down-regulated and tight junction protein expression (e.g., ZO-1) was maintained, which sequentially suppressed the epithelial-to-mesenchymal transition of tubular epithelial cells (TECs). Exosomes purified from MSC-CM exerted an anti-apoptotic effect and protected tight junction structure in TECs. The increase of glomerular mesangium substrate was inhibited in HFD-diabetic mice. MSC therapy is a promising tool to prevent DN via the paracrine effect of renal trophic factors including exosomes due to its multifactorial action. PMID:27721418

    1983-09-01

    Six protozoa-free steers with simple rumen and abomasal cannulas were given basal diets consisting of a concentrate mixture of flaked maize and tapioca with either barley straw (BS) or alkali-treated barley straw (BSA). Other diets used were supplemented with urea (BSU and BSAU respectively) or contained fish meal in place of tapioca BSF and BSAF respectively). The diets were given in a 6 X 6 Latin square design. Diets were isoenergetic and provided sufficient metabolizable energy (ME) to support a growth rate of approximately 0.5 kg/d. Basal diets, urea- and fish-meal-supplemented diets had estimated rumen-degradable nitrogen (RDN):ME values (g/MJ) of 0.5, 1.2 and 0.8 respectively. 103Ruthenium and polyethylene glycol were given as flow markers, and flows (g/24 h) at the abomasum of organic matter (OM) and carbohydrate components were calculated. True digestibility coefficients of OM between mouth and abomasum were significantly greater for diets containing alkali-treated straw (approximately 0.63) than for those containing untreated straw (approximately 0.55) but were not significantly affected by N supplementation. Digestibility coefficients of the neutral-sugar components of dietary polysaccharides between mouth and abomasum were 0.28, 0.34, 0.31, 0.23, 0.31 and 0.87 for mannose, galactose arabinose, xylose, cellulose-glucose and starch-glucose respectively for diet BS. Corresponding values were 0.37, 0.42, 0.56, 0.51, 0.40 and 0.88 for diet BSA. All but the mannose and starch-glucose values were significantly greater for the latter diet. N supplementation also led to increases in digestibility of all neutral sugars except mannose and starch-glucose. Fish meal produced a markedly greater effect than urea but only significantly so for cellulose-glucose. Thus, the highest digestibilities were seen for diet BSAF and were 0.68, 0.67, 0.74 and 0.64 for galactose, arabinose, xylose and cellulose-glucose respectively. Of all these sugars xylose consistently showed the

    It has been hypothesized that a high intake of dairy protein may increase prostate cancer risk by increasing the production of insulin-like growth factor 1 (IGF-1). Several single nucleotide polymorphisms (SNPs) have been weakly associated with circulating concentrations of IGF-1 and IGF binding protein 3 (IGFBP-3), but none of these SNPs was associated with risk of prostate cancer. We examined whether an association between 16 SNPs associated with circulating IGF-1 or IGFBP-3 concentrations and prostate cancer exists within subgroups defined by dietary protein intake in 5,253 cases and 4,963 controls of European ancestry within the NCI Breast and Prostate Cancer Cohort Consortium (BPC3). The BPC3 includes nested case-control studies within large North-American and European cohorts. Per-allele odds ratios for prostate cancer for the SNPs were compared across tertiles of protein intake, which was expressed as the percentage of energy derived from total, animal, dairy or plant protein sources, using conditional logistic regression models. Total, animal, dairy and plant protein intakes were significantly positively associated with blood IGF-1 (p  0.10) or with risk of prostate cancer (p > 0.20). After adjusting for multiple testing, the SNP-prostate cancer associations did not differ by intakes of protein, although two interactions by intake of plant protein were of marginal statistical significance [SSTR5 (somatostatin receptor 5)-rs197056 (uncorrected p for interaction, 0.001); SSTR5-rs197057 (uncorrected p for interaction, 0.002)]. We found no strong evidence that the associations between 16 IGF pathway SNPs and prostate cancer differed by intakes of dietary protein.

    Glucose tolerance and concentrations of insulin, growth hormone (GH) and insulin-like growth factor-I (IGF-I) were evaluated in lambs deficient, marginal or adequate in zinc (Zn). Lambs were fed a semipurified diet that contained either 3.7, 8.7, or 43.7 mg Zn/kg. Zinc deficiency resulted in lower serum insulin levels 1 h after feeding while levels in marginal lambs were not different from that of adequate lambs. Dietary Zn did not affect plasma glucose post feeding. One h after IV glucose administration plasma glucose concentrations were lower in deficient lambs compared to adequate lambs; marginal lambs had intermediate glucose levels. Concentration of GH before and after feeding or glucose challenge were not affected by Zn status; however, serum IGF-I was lower in deficient than in marginal or adequate lambs. A GH releasing factor (GRF) analog was given to evaluate the release of GH. Serum GH in response to GRF challenge was higher in deficient lambs and tended to be higher in marginal lambs when compared to adequate lambs. Impaired growth observed with Zn deficiency may be mediated in part by its effect on insulin, GH and IGF-I concentrations.

Cheetahs fed raw meat diets had the highest prevalence of soft faeces with no shape (22%, as well as of firm and dry faeces (40%. No broad category of diet exerted any influence on the health parameters investigated. However, feeding of ribs at least once per week reduced the odds of diarrhoea (P = 0.020 and feeding of long bones (limbs at least once per week was associated with a lower odds of vomiting (P = 0.008. Cheetahs fed muscle meat at least once per week had reduced odds of suffering from chronic gastritis (P = 0.005 or non-specific gastrointestinal disease (P < 0.001. The only factor identified as increasing the odds of chronic gastritis was feeding of horse "often" or "always" (P = 0.023. The findings of the current study build on existing empirical research to support a recommendation towards a greater inclusion of skeletal components. Current husbandry guidelines advocating the use of supplemented raw meat diets are likewise supported, but the use of horse meat, as well as commercially prepared diets for captive cheetahs, warrants caution until further research is conducted.

    The present study was aim to evaluate the association between very long chain saturated fatty acids (VLSFAs) and metabolic syndrome (MetS) in Korean population. The study population were recruited from the Korea National Health and Nutrition Examination Survey VI (2013). Using the cross-sectional study design, socio-demographic factors, medical history, and clinical measurements were investigated according to quartiles of VLSFAs intake. The associations between each and sum of VLSFAs intake and MetS were assessed by logistic regression. The result indicated that higher intake of VLSFAs was significantly associated with favorable metabolic status, including lower levels of circulating triglyceride (TG) (p < 0.05). Additionally, subjects with higher intake of arachidic acid and total VLSFAs were negatively associated with MetS risk compared to subjects with lower intake of those fatty acids (p < 0.05). In conclusion, dietary VLSFAs intake was associated with metabolic risk factors and lower risk of MetS in Korean population.

    Full Text Available Abstract Background Pediatric obesity has become a global public health problem. Data on the lifestyle behaviors, dietary habits, and familial factors of overweight and obese children and adolescents are limited. The present study aims to compare health-related factors among normal-weight, overweight, and obese Chinese children and adolescents. Methods We conducted a cross-sectional study consisted of 4262 children and adolescents aged 5–18 years old from rural areas of the northeast China. Anthropometric measurements and self-reported information on health-related variables, such as physical activities, sleep duration, dietary habits, family income, and recognition of weight status from the views of both children and parents, were collected by trained personnel. Results The prevalence rates of overweight and obesity were 15.3 and 6.4%, respectively. Compared to girls, boys were more commonly overweight (17.5% vs. 12.9% and obese (9.5% vs. 3.1%. Approximately half of the parents with an overweight or obese child reported that they failed to recognize their child’s excess weight status, and 65% of patients with an overweight child reported that they would not take measures to decrease their child’s body weight. Obese children and adolescents were more likely to be nonsnackers [odds ratio (OR: 1.348; 95% confidence interval (CI: 1.039–1.748] and to have a family income of 2000 CNY or more per month (OR: 1.442; 95% CI: 1.045–1.99 and less likely to sleep longer (≥7.5 h (OR: 0.475; 95% CI: 0.31–0.728 than the normal-weight participants. Conclusions Our study revealed a high prevalence of overweight and obesity in a large Chinese pediatric population. Differences in sleep duration, snacking, family income, and parental recognition of children’s weight status among participants in different weight categories were observed, which should be considered when planning prevention and treatment programs for pediatric obesity.

    Agriculture accounts for ~90% of India's fresh water use, and there are concerns that future food production will be threatened by insufficient water supply of adequate quality. This study aimed to quantify the water required in the production of diets in India using the water footprint (WF) assessment method. The socio-demographic associations of dietary WFs were explored using mixed effects regression models with a particular focus on blue (irrigation) WF given the importance for Indian agriculture. Dietary data from ~7000 adults living in India were matched to India-specific WF data for food groups to quantify the blue and green (rainfall) WF of typical diets. The mean blue and green WF of diets was 737l/capita/day and 2531l/capita/day, respectively. Vegetables had the lowest WFs per unit mass of product, while roots/tubers had the lowest WFs per unit dietary energy. Poultry products had the greatest blue WFs. Wheat and rice contributed 31% and 19% of the dietary blue WF respectively. Vegetable oils were the highest contributor to dietary green WF. Regional variation in dietary choices meant large differences in dietary blue WFs, whereby northern diets had nearly 1.5 times greater blue WFs than southern diets. Urban diets had a higher blue WF than rural diets, and a higher standard of living was associated with larger dietary blue WFs. This study provides a novel perspective on the WF of diets in India using individual-level dietary data, and demonstrates important variability in WFs due to different food consumption patterns and socio-demographic characteristics. Future dietary shifts towards patterns currently consumed by individuals in higher income groups, would likely increase irrigation requirements putting substantial pressure on India's water resources.

    Full Text Available Background: Although imbalances in dietary intakes can have short and longer term influences on the health of preschool children, few tools exist to quickly and easily identify nutritional risk in otherwise healthy young children. Objectives: To develop and test the validity of a parent-administered questionnaire (NutricheQ as a means of evaluating dietary risk in young children (12–36 months. Design: Following a comprehensive development process and internal reliability assessment, the NutricheQ questionnaire was validated in a cohort of 371 Irish preschool children as part of the National Preschool Nutrition Survey. Dietary risk was rated on a scale ranging from 0 to 22 from 11 questions, with a higher score indicating higher risk. Results: Children with higher NutricheQ scores had significantly (p<0.05 lower mean daily intakes of key nutrients such as iron, zinc, vitamin D, riboflavin, niacin, folate, phosphorous, potassium, carotene, retinol, and dietary fibre. They also had lower (p<0.05 intakes of vegetables, fish and fish dishes, meat and infant/toddler milks and higher intakes of processed foods and non-milk beverages, confectionery, sugars and savoury snack foods indicative of poorer dietary quality. Areas under the curve values of 84.7 and 75.6% were achieved for ‘medium’ and ‘high’ dietary risk when compared with expert risk ratings indicating good consistency between the two methods. Conclusion: NutricheQ is a valid method of quickly assessing dietary quality in preschoolers and in identifying those at increased nutritional risk.In ContextAnalysis of data from national food and nutrition surveys typically identifies shortfalls in dietary intakes or quality of young children. This can relate to intakes of micronutrients such as iron or vitamin D as well as to the balance of macronutrients they consume (e.g. fat or sugar. Alongside this lie concerns regarding overweight and obesity and physical inactivity. This combination of

    Dietary habits established in early childhood contribute to lifelong dietary pattern and the development of early risk factors for disease in adulthood. Although a large body of epidemiologic data from Western countries show that the dietary pattern of children is influenced by maternal socio-economic and lifestyle characteristics, information on this topic in non-Western countries is absolutely lacking. The present study identified dietary patterns among infants aged 16-24 months, and then examined the influence of maternal socio-economic and lifestyle characteristics on identified dietary patterns. Subjects were 758 Japanese mother-child pairs. Dietary data of infants were collected from the mothers using a questionnaire. Dietary patterns were extracted from the consumption of 15 foods (times week(-1)) by cluster analysis. The following two dietary patterns were identified: 'fruits, vegetables and high-protein foods' (n = 483) and 'confectionaries and sweetened beverages' (n = 275) patterns. After adjustment for all other predictors, maternal educational level, number of infants' siblings and maternal dietary patterns were independently associated with dietary patterns of infants. Infants whose mothers had a higher educational level and the 'rice, fish and vegetables' dietary pattern were less likely to belong to the 'confectionaries and sweetened beverages' pattern, whereas infants whose mothers had a higher number of children and the 'wheat product' dietary pattern were more likely to belong to the 'confectionaries and sweetened beverages' than the 'fruits, vegetables and high-protein foods' pattern. In conclusion, the mother's socio-economic position and dietary patterns were associated with the dietary patterns of infants in the Japanese pairs as observed in the Western populations.

    Full Text Available Abstract Background The PTEN tumour suppressor gene and PIK3CA proto-oncogene encode proteins which contribute to regulation and propagation of signal transduction through the PI3K/AKT signalling pathway. This study investigates the prevalence of loss of PTEN expression and mutations in both PTEN and PIK3CA in colorectal cancers (CRC and their associations with tumour clinicopathological features, lifestyle factors and dietary consumptions. Methods 186 adenocarcinomas and 16 adenomas from the EPIC Norfolk study were tested for PTEN and PIK3CA mutations by DNA sequencing and PTEN expression changes by immunohistochemistry. Dietary and lifestyle data were collected prospectively using seven day food diaries and lifestyle questionnaires. Results Mutations in exons 7 and 8 of PTEN were observed in 2.2% of CRC and PTEN loss of expression was identified in 34.9% CRC. Negative PTEN expression was associated with lower blood low-density lipoprotein concentrations (p = 0.05. PIK3CA mutations were observed in 7% of cancers and were more frequent in CRCs in females (p = 0.04. Analysis of dietary intakes demonstrated no link between PTEN expression status and any specific dietary factor. PTEN expression negative, proximal CRC were of more advanced Dukes' stage (p = 0.02 and poor differentiation (p PIK3CA mutations and loss of PTEN expression demonstrated that these two events were independent (p = 0.55. Conclusion These data demonstrated the frequent occurrence (34.9% of PTEN loss of expression in colorectal cancers, for which gene mutations do not appear to be the main cause. Furthermore, dietary factors are not associated with loss of PTEN expression. PTEN expression negative CRC were not homogenous, as proximal cancers were associated with a more advanced Dukes' stage and poor differentiation, whereas distal cancers were associated with earlier Dukes' stage.

    Obesity has reached epidemic proportions world-wide. Its risk factors are poorly studied, especially among children in developing countries such as Algeria. The purpose of this study was therefore to determine the prevalence and risk factors of obesity in Algerian schoolchildren 6 to 8 years aged by conducting a school-site retrospective cohort study in Tlemcen Department (western Algeria).Material and Mthods: From 2008 to 2010, socio-demographic characteristics, body mass index (BMI), physical activity categories, lifestyle and nutritional habits of 1520 children (839 boys and 681 girls), at entrance into primary school, were recorded using a self-administered questionnaire. Among the 1520 participants, 99 (6.5%) were obese. Birthweight ≤ 2.5 kg and ≥ 4 kg, early introduction of solid foods and low physical activity were significantly associated with obesity (peducation, household income and the presence of familial obesity may predispose significantly to childhood obesity (pAlgeria. Preventive measures should focus on the promotion of physical activity and maternal and children nutritional education.

    A cross-sectional study on 215 university female students aged 18-30 years was undertaken in 1993 to examine some factors associated with obesity among this group of females. Based on Body Mass Index (BMI), (wt/ht2), 19% of females were overweight and 9.8% were obese. The proportion of obesity was the highest in females aged 18 years (31%) compared to those aged 19 and 20 years and above (23.8% and 27.6%, respectively). Although there was no significant association between obesity and social factors studied, the prevalence of obesity was higher in non-national, those with educated mothers, having no housemaid, and having a family history of obesity. Skipping meals and snacks had no significant association with obesity, however, obesity was more prevalent among females who did not skip lunch. In contrast, females who ate afternoon snacks and supper were more likely to be obese than females who skipped these events. Median BMI for university females was higher than that reported in USA for the same age group, while median values for weight and mid-arm circumference for females studied were similar to that reported in their counterparts in Western countries.

    Individual response to dietary interventions can be highly variable. The phenotypic characteristics of those who will respond positively to personalised dietary advice are largely unknown. The objective of this study was to compare the phenotypic profiles of differential responders to personalised dietary intervention, with a focus on total circulating cholesterol. Subjects from the Food4Me multi-centre study were classified as responders or non-responders to dietary advice on the basis of the change in cholesterol level from baseline to month 6, with lower and upper quartiles defined as responder and non-responder groups, respectively. There were no significant differences between demographic and anthropometric profiles of the groups. Furthermore, with the exception of alcohol, there was no significant difference in reported dietary intake, at baseline. However, there were marked differences in baseline fatty acid profiles. The responder group had significantly higher levels of stearic acid (18 : 0, P=0·034) and lower levels of palmitic acid (16 : 0, P=0·009). Total MUFA (P=0·016) and total PUFA (P=0·008) also differed between the groups. In a step-wise logistic regression model, age, baseline total cholesterol, glucose, five fatty acids and alcohol intakes were selected as factors that successfully discriminated responders from non-responders, with sensitivity of 82 % and specificity of 83 %. The successful delivery of personalised dietary advice may depend on our ability to identify phenotypes that are responsive. The results demonstrate the potential use of metabolic profiles in identifying response to an intervention and could play an important role in the development of precision nutrition.

    Dietary flavonoid apigenin is expected to have preventive and therapeutic potential against malignant tumors. In this report, we show for the first time that apigenin markedly induces the expression of death receptor 5 (DR5) and synergistically acts with exogenous soluble recombinant human tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) to induce apoptosis in malignant tumor cells. TRAIL is a promising candidate for cancer therapeutics due to its ability to selectively induce apoptosis in cancer cells. The combined use of apigenin and TRAIL at suboptimal concentrations induces Bcl-2-interacting domain cleavage and the activation of caspases-8, -10, -9, and -3. Furthermore, human recombinant DR5/Fc chimera protein and caspase inhibitors dramatically inhibit apoptosis induced by the combination of apigenin and TRAIL. On the other hand, apigenin-mediated induction of DR5 expression is not observed in normal human peripheral blood mononuclear cells. Moreover, apigenin does not sensitize normal human peripheral blood mononuclear cells to TRAIL-induced apoptosis. These results suggest that this combined treatment with apigenin and TRAIL might be promising as a new therapy against malignant tumors.

    Urinary excretion of 34 dietary polyphenols and their variations according to diet and other lifestyle factors were measured by tandem mass spectrometry in 475 adult participants from the European Prospective Investigation into Cancer and Nutrition (EPIC) cross-sectional study. A single 24-hour urine sample was analysed for each subject from 4 European countries. The highest median levels were observed for phenolic acids such as 4-hydroxyphenylacetic acid (157 μmol/24 h), followed by 3-hydroxyphenylacetic, ferulic, vanillic and homovanillic acids (20–50 μmol/24 h). The lowest concentrations were observed for equol, apigenin and resveratrol (polyphenols significantly varied by centre, followed by alcohol intake, sex, educational level, and energy intake. This variability is largely explained by geographical variations in the diet, as suggested by the high correlations (r > 0.5) observed between urinary polyphenols and the intake of their main food sources (e.g., resveratrol and gallic acid ethyl ester with red wine intake; caffeic, protocatechuic and ferulic acids with coffee consumption; and hesperetin and naringenin with citrus fruit intake). The large variations in urinary polyphenols observed are largely determined by food preferences. These polyphenol biomarkers should allow more accurate evaluation of the relationships between polyphenol exposure and the risk of chronic diseases in large epidemiological studies. PMID:27273479

    Understanding the overall dietary patterns of a population is a key step in initiating appropriate nutritional interventions and policies. Studies characterising the dietary patterns of Nigerian mothers and children are lacking. Complete dietary data for 13,566 mothers and their 13,506 children were analysed from the 2008 Nigerian Demographic and Health Surveys (NDHS), a nationally representative sample, to identify the overall maternal and child dietary patterns and to study the potential determinants of such dietary patterns. The 2008 NDHS included questions that inquired about the food items mothers and their children had consumed during the 24 h preceding the day of the interview. Factor analysis with the principal component procedure was used to construct the dietary patterns, and multiple multilevel logistic regression was used to investigate the determinants of the dietary patterns. Four ('mixed', 'traditional', 'staple foods and milk products' and 'beverages') and five ('mixed', 'selective', 'beverages and candies', 'gruels, grains and semi-solids' and 'infant formula and cereals') distinct dietary patterns were obtained for the mothers and children, respectively. The key determinants of both maternal and child dietary patterns were month of interview, religion, region of residence, maternal education, maternal occupation, wealth index and maternal body mass index. Marital status additionally predicted maternal patterns, while sex of the child, number of siblings, child's age, maternal age and place of residence additionally determined the child's patterns. This study has identified four and five different dietary patterns to characterise the dietary habits of Nigerian mothers and their children, respectively, and has shown the important socio-economic/demographic factors influencing the dietary patterns, which can guide appropriate nutritional interventions among Nigerian mothers and children. © 2012 Blackwell Publishing Ltd.

    Colorectal cancer (CRC) is the most common cancer in non-smokers posing a significant health burden in the UK. Observational studies lend support to the impact of environmental factors especially diet on colorectal carcinogenesis. Significant advances have been made in understanding the biology of CRC carcinogenesis in particular epigenetic modifications such as DNA methylation. DNA methylation is thought to occur at least as commonly as inactivation of tumor suppressor genes. In fact compared with other human cancers, promoter gene methylation occurs most commonly within the gastrointestinal tract. Emerging data suggest the direct influence of certain micronutrients for example folic acid, selenium as well as interaction with toxins such as alcohol on DNA methylation. Such interactions are likely to have a mechanistic impact on CRC carcinogenesis through the methylation pathway but also, may offer possible therapeutic potential as nutraceuticals.

    The majority of colon tumors are driven by aberrant Wnt signaling in intestinal stem cells, which mediates an efficient route toward initiating intestinal cancer. Natural lipophilic polyphenols and long-chain polyunsaturated fatty acids (PUFAs) generally suppress Wnt- and NF-κB- (nuclear factor-κ light-chain enhancer of activated B-cell) related pathways. However, the effects of these extrinsic agents on colonic leucine-rich repeat-containing G-protein-coupled receptor 5-positive (Lgr5(+)) stem cells, the cells of origin of colon cancer, have not been documented to date. Therefore, we examined the effect of n-3 PUFA and polyphenol (curcumin) combination on Lgr5(+) stem cells during tumor initiation and progression in the colon compared with an n-6 PUFA-enriched control diet. Lgr5-EGFP-IRES-(creERT2) knock-in mice were fed diets containing n-6 PUFA (control), n-3 PUFA, n-6 PUFA+curcumin or n-3 PUFA+curcumin for 3 weeks, followed by 6 azoxymethane (AOM) injections, and terminated 17 weeks after the last injection. To further elucidate the effects of the dietary bioactives at the tumor initiation stage, Lgr5(+) stem cells were also assessed at 12 and 24 h post AOM injection. Only n-3 PUFA+curcumin feeding reduced nuclear β-catenin in aberrant crypt foci (by threefold) compared with control at the progression time point. n-3 PUFA+curcumin synergistically increased targeted apoptosis in DNA-damaged Lgr5(+) stem cells by 4.5-fold compared with control at 12 h and maximally reduced damaged Lgr5(+) stem cells at 24 h, down to the level observed in saline-treated mice. Finally, RNAseq analysis indicated that p53 signaling in Lgr5(+) stem cells from mice exposed to AOM was uniquely upregulated only following n-3 PUFA+curcumin cotreatment. These novel findings demonstrate that Lgr5(+) stem cells are uniquely responsive to external dietary cues following the induction of DNA damage, providing a therapeutic strategy for eliminating damaged Lgr5(+) stem cells to reduce

Firstly, these compounds are responsible for the proper functioning of cell membranes, by ensuring liquidity and permeability, which is pivotal for normal activity of membrane proteins, including receptors. These mechanisms are at the core of prevention of cancer, autoimmune or neurological disorders. Secondly, structure and properties of phospholipids cause that they are highly available source of biologically active fatty acids. Thirdly, also products of endogenous hydrolysis of phospholipids exhibit biological activity. These include lysophospholipids formed as a result of disconnecting free fatty acid from glycerophospholipids in the reaction catalyzed by phospholipase A, phosphatidic acid and hydrophilic subunits released by the activity of phospholipase D. The bioactive products of hydrolysis also include ceramides liberated from phosphosphingolipids after removal of a hydrophilic unit catalyzed by sphingomyelinase. Phospholipids are supplied to the human body with food. A high content of phospholipids is characteristic for egg yolk, liver, pork and poultry, as well as some soy products. Particularly beneficial are phospholipids derived from seafood because they are a rich source of essential fatty acids of the n-3 family.

    Study Type - Prognosis (cohort series) Level of Evidence 2a What's known on the subject? and What does the study add? Preoperative thrombocytosis has been identified as a predictor of poor outcome in various cancer types. However, the prognostic role of platelet count in patients with invasive bladder cancer undergoing radical cystectomy is unknown. The present study demonstrates that preoperative thrombocytosis is an independent risk factor for decreased cancer-specific survival after radical treatment of invasive bladder cancer. We developed a new prognostic scoring model for cancer-specific outcomes after radical cystectomy including platelet count and established pathological risk factors. Consideration of platelet count in the final model increased its predictive accuracy significantly. Thrombocytosis may be a useful parameter to include within established international bladder cancer nomograms. •  To investigate the oncological significance of preoperative thrombocytosis in patients with invasive bladder cancer undergoing radical cystectomy, as it has been reported as a marker for aggressive tumour biology in a variety of solid tumours. •  The series comprised 258 patients undergoing radical cystectomy between 1999 and 2010 in whom different clinical and histopathological parameters were assessed. •  Elevated platelet count was defined as >450 × 10(9) /L. •  Based on regression estimates of significant parameters in multivariable analysis a new weighted scoring model was developed to predict cancer-specific outcomes. •  The median follow-up was 30 months (6-116). •  Of the 258 patients, 26 (10.1%) had elevated and 232 (89.9%) had normal platelet count. The 3-year cancer-specific survival in patients with normal and elevated platelet count was 61.5% and 32.7%, respectively (P thrombocytosis (2.68, 1.26-5.14; P= 0.011). •  The 3-year cancer-specific survival in patients with a score 0 (low risk), 1-2 (intermediate risk) and 3

    Full Text Available Abstract Background Fibroblast growth factor 21 (FGF21, whose expression is induced by peroxisome proliferator-activated receptor α (PPARα, has been recently identified as a novel metabolic regulator which plays a crucial role in glucose homeostasis, lipid metabolism, insulin sensitivity and obesity. Previous studies have shown that administration of oxidized fats leads to an activation of PPARα in the liver. Therefore, the present study investigated the hypothesis that feeding of oxidized fats causes an induction of FGF21 in the liver. Methods Twenty four crossbred pigs were allocated to two groups of 12 pigs each and fed nutritionally adequate diets with either fresh rapeseed oil or oxidized rapeseed oil prepared by heating at a temperature of 175°C for 72 h. Results In pigs fed the oxidized fat mRNA abundance and protein concentrations of FGF21 in liver were significantly increased (P P P Conclusion The present study shows for the first time that administration of an oxidized fat induces the expression of FGF21 in the liver, probably mediated by activation of PPARα. Induction of FGF21 could be involved in several effects observed in animals administered an oxidized fat.

    Trace elements in certain amounts are essential for childrens' health, because they are present in tissues participating in metabolic reactions of organisms. Deficiency of the essential elements may result in malnutrition, impaired body immunity, and poor resistance to disease. These conditions might be enhanced against a background of additional adverse environmental factors such as toxic elements. The analysis of elements in childrens' hair will give information on the deficiency of essential elements and excess of toxic elements in relation to their diet. In this study, 141 hair samples from children (girls and boys) living in two regions of Tanzanian mainland (Dar es Salaam and Moshi) and the island of Zanzibar have been analysed for trace elements in relation to food consumption habits. The analysis was carried out using long and short irradiation instrumental neutron activation analysis (INAA) of the Nuclear Physics Institute at Rez, Czech Republic. Arithmetic and geometric means with their respective standard deviations are presented for 19 elements. Subgroups were formed according to age, gender, and geographic regions from which the samples were collected. Differences in concentrations for the groups and with other childhood populations were explored and discussed.

    The identification of a hot spot of exceptional longevity, the Longevity Blue Zone (LBZ), in the mountain population of Sardinia has aroused considerable interest toward its traditional food as one of the potential causal factors. This preliminary study on the traditional Sardinian diet has been supported by the literature available, which has been carefully reviewed and compared. Up to a short time ago, the LBZ population depended mostly upon livestock rearing, and consumption of animal-derived foods was relatively higher than in the rest of the island. The nutrition transition (NT) in urbanized and lowland areas began in the mid-1950s, fueled by economic development, whereas in the LBZ it started later owing to prolonged resistance to change by a society organized around a rather efficient pastoral economy. Even nowadays a large proportion of the population in this area still follows the traditional diet based on cereal-derived foods and dairy products. The LBZ cohorts comprising individuals who were of a mature age when NT began may have benefited both from the high-quality, albeit rather monotonous, traditional diet to which they had been exposed most of their life and from the transitional diet, which introduced positive changes such as more variety, increased consumption of fruits and vegetables and moderate meat intake. It could be speculated that these changes may have brought substantial health benefits to this particular aging group, which was in need of nutrient-rich food at this specific time in life, thereby resulting in a decreased mortality risk and, in turn, life-span extension.

    Maintenance of a balance between commensal bacteria and the mucosal immune system is crucial and intestinal dysbiosis may be a key event in the pathogenesis of colorectal cancer (CRC). The toll-like receptor 4 (TLR4) is an important pattern-recognition receptor that regulates inflammation...... and barrier function in the gut by a mechanism that involves activation of the nuclear factor-kappa B (NF-kappa B) transcription factor. Dietary and life style factors may impact these functions. We therefore used a Danish prospective case-cohort study of 1010 CRC cases and 1829 randomly selected participants...

    AIM: Hypermethylation of the promoter of the hMLH1gene, which plays an important role in mismatch repair during DNA replication, occurs in more than 30% of human gastric cancer tissues. The purpose of this study was to investigate the effects of environmental factors, genetic polymorphisms of major metabolic enzymes, and microsatellite instability on hypermethylation of the promoter of the hMLH1 gene in gastric cancer.METHODS: Data were obtained from a hospital-based,case-control study of gastric cancer. One hundred and ten gastric cancer patients and 220 age- and sex-matched control patients completed a structured questionnaire regarding their exposure to environmental risk factors.Hypermethylation of the hMLH1 gene promoter,polymorphisms of the GSTM1, GSTT1, CYP1A1, CYP2E1,ALDH2 and L-myc genes, microsatellite instability and mutations of p53 and Ki-ras genes were investigated.RESULTS: Both smoking and alcohol consumption were associated with a higher risk of gastric cancer with hypermethylation of the hMLH1 gene promoter. High intake of vegetables and low intake of potato were associated with increased likelihood of gastric cancer with hypermethylation of the hMLH1 gene promoter. Genetic polymorphisms of the GSTM1, GSTT1, CYP1A1, CYP2E1,ALDH2, and L-mycgenes were not significantly associated with the risk of gastric cancer either with or without hypermethylation in the promoter of the hMLH1 gene.Hypermethylation of the hMLH1 promoter was significantly associated with microsatellite instability (MSI): 10 of the 14 (71.4%) MSI-positive tumors showed hypermethylation,whereas 28 of 94 (29.8%) the MSI-negative tumors were hypermethylated at the hMLH1 promoter region.Hypermethylation of the hMLH1 gene promoter was significantly inversely correlated with mutation of the p53gene.CONCLUSION: These results suggest that cigarette smoking and alcohol consumption may influence the development of hMLH1-positive gastric cancer. Most dietary factors and polymorphisms of GSTM1

    Full Text Available Obesity is associated with a hypercoagulable state and increased risk for thrombotic cardiovascular events.Establish the onset and reversibility of the hypercoagulable state during the development and regression of nutritionally-induced obesity in mice, and its relation to transcriptional changes and clearance rates of coagulation factors as well as its relation to changes in metabolic and inflammatory parameters.Male C57BL/6J mice were fed a low fat (10% kcal as fat; LFD or high fat diet (45% kcal as fat; HFD for 2, 4, 8 or 16 weeks. To study the effects of weight loss, mice were fed the HFD for 16 weeks and switched to the LFD for 1, 2 or 4 weeks. For each time point analyses of plasma and hepatic mRNA levels of coagulation factors were performed after overnight fasting, as well as measurements of circulating metabolic and inflammatory parameters. Furthermore, in vivo clearance rates of human factor (F VII, FVIII and FIX proteins were determined after 2 weeks of HFD-feeding.HFD feeding gradually increased the body and liver weight, which was accompanied by a significant increase in plasma glucose levels from 8 weeks onwards, while insulin levels were affected after 16 weeks. Besides a transient rise in cytokine levels at 2 weeks after starting the HFD, no significant effect on inflammation markers was present. Increased plasma levels of fibrinogen, FII, FVII, FVIII, FIX, FXI and FXII were observed in mice on a HFD for 2 weeks, which in general persisted throughout the 16 weeks of HFD-feeding. Interestingly, with the exception of FXI the effects on plasma coagulation levels were not paralleled by changes in relative transcript levels in the liver, nor by decreased clearance rates. Switching from HFD to LFD reversed the HFD-induced procoagulant shift in plasma, again not coinciding with transcriptional modulation.Changes in dietary fat content rapidly alter the mouse plasma coagulation profile, thereby preceding plasma metabolic changes, which

    To assess the association of parents' nutritional status, and dietary and sociodemographic factors with overweight/obesity in schoolchildren in Florianópolis Island, Santa Catarina State, Brazil, this cross-sectional epidemiological study examined 2,826 schoolchildren 7 to 14 years old, classified according to body mass index curves for age and sex recommended by the International Obesity Task Force. Data were analyzed using Poisson regression. The final model showed overweight/obesity in boys associated directly with father's educational level, mother's age, and parents' nutritional status, and inversely with mother's educational level, and number of daily meals. Among girls, it associated directly with parents' nutritional status and the schoolchildren's age, and inversely with consumption of risk foods. The variables that associated with overweight/obesity differed between the sexes, except parents' nutritional status. Boys and girls with both parents overweight or obese were, respectively, 80% and 150% more likely to exhibit the same diagnosis, indicating the need for interventions that include the family environment.

    The effects of both the amount and quality of dietary fat have been studied intensively during the past decades. Previously, low-fat diets were recommended without much attention to the quality of fat, whereas there is general emphasis on the quality of fat in current guidelines. The objective of this systematic review (SR) was to assess the evidence of an effect of the amount and type of dietary fat on body weight (BW), risk factors, and risk of non-communicable diseases, that is, type 2 diabetes (T2DM), cardiovascular diseases (CVD), and cancer in healthy subjects or subjects at risk for these diseases. This work was performed in the process of updating the fourth edition of the Nordic Nutrition Recommendations from 2004. The literature search was performed in October 2010 covering articles published since January 2000. A complementary search was done in February 2012 covering literature until December 2011. Two authors independently selected articles for inclusion from a total of about 16,000 abstracts according to predefined criteria. Randomized controlled trials (RCT) and prospective cohort studies (PCS) were included as well as nested case-control studies. A few retrospective case-control studies were also included when limited or no data were available from other study types. Altogether 607 articles were quality graded and the observed effects in these papers were summarized. Convincing evidence was found that partial replacement of saturated fat (SFA) with polyunsaturated fat (PUFA) or monounsaturated fat (MUFA) lowers fasting serum/plasma total and LDL cholesterol concentrations. The evidence was probable for a decreasing effect of fish oil on concentration of serum/plasma total triglycerides as compared with MUFA. Beneficial effect of MUFA both on insulin sensitivity and fasting plasma/serum insulin concentration was considered as probable in comparisons of MUFA and carbohydrates versus SFA, whereas no effect was found on fasting glucose concentration in

  17. Dietary Modulation Of Rumen Metabolism: A Key Factor To Enhancing Ruminant Production

    Directory of Open Access Journals (Sweden)

    2012-09-01

    Full Text Available Owing to microbial hydrolysis of nutrients in the rumen, ruminants are relatively efficient animals for livestock production considering that they can utilize low-quality feeds including industrial by-products. On the other hand, however, they also contribute to global warming because of their methane emission from the enteric fermentation. The methane emission not only affects the environment but also represents the loss of consumed energy. Thus, mitigating enteric methane emission may improve animal production efficiency as well as contribute to alleviate the impact of ruminants on climate change. This review focuses on various achievements of the last years which have expanded our knowledge regarding mitigation of enteric methanogenesis and its potential contribution in improving cattle production efficiency. The article also discusses the role of nutrition and rumen metabolism on gut and host’s health status as well as on enhancement of product quality of cattle products. The improvement of quality of ruminant products relies mainly on improving their fatty acids composition toward health-promoting polyunsaturated fatty acid profile such as omega-3 fatty acids and conjugated linolenic acids. Plant secondary compounds appear to possess multi-beneficial effects that when fed to ruminants can beneficially modify rumen metabolism, contributing to methane mitigation, gut health, food safety and quality. However, identification of active compounds for use as feed additives in ruminant production and understanding their mode of specific actions remain a big challenge for research.

    The effect of the number of pesticide residue values below the LOQ/LOD of analytical methods, the variability of residues in individual fruits, mass of fruit units and the number of bootstrap iterations was studied on the probabilistically estimated acute exposure of consumers. The 4720 daily apple consumption data and the results of 1239 apple sample analyses for captan residues, performed within the Hungarian monitoring programme between 2005 and 2011, were used in this study as model matrix. Up to about 95th percentile exposure (µg/(kg bw·day)), simply multiplying each residue in composite samples with each consumption value gave similar estimates to those obtained with the complex procedure taking also into account the mass of and residues in individual fruits. However, the exposure above the 95th percentile calculated with the complex procedure gradually increased with increasing percentile level compared to the simple procedure. Including the high number of non-detects reduced the estimated exposure, which was the highest when only the residues measured in treated fruits were taken into account. The number of bootstrap iterations between 100 and 10,000 did not significantly affect the calculated exposure. The 99.99th percentile exposure amounted to 17.9% of the acute reference dose of 300 µg/(kg bw·day) for women of childbearing age.

    Full Text Available Abstract Background Several studies witnessed that prenatal zinc deficiency (ZD predisposes to diverse pregnancy complications. However, scientific evidences on the determinants of prenatal ZD are scanty and inconclusive. The purpose of the present study was to assess the prevalence and determinants of prenatal ZD in Sidama zone, Southern Ethiopia. Methods A community based, cross-sectional study was conducted in Sidama zone in January and February 2011. Randomly selected 700 pregnant women were included in the study. Data on potential determinants of ZD were gathered using a structured questionnaire. Serum zinc concentration was measured using Atomic Absorption Spectrometry. Statistical analysis was done using logistic regression and linear regression. Results The mean serum zinc concentration was 52.4 (+/-9.9 μg/dl (95% CI: 51.6-53.1 μg/dl. About 53.0% (95% CI: 49.3-56.7% of the subjects were zinc deficient. The majority of the explained variability of serum zinc was due to dietary factors like household food insecurity level, dietary diversity and consumption of animal source foods. The risk of ZD was 1.65 (95% CI: 1.02-2.67 times higher among women from maize staple diet category compared to Enset staple diet category. Compared to pregnant women aged 15-24 years, those aged 25-34 and 35-49 years had 1.57 (95% CI: 1.04-2.34 and 2.18 (95% CI: 1.25-3.63 times higher risk of ZD, respectively. Women devoid of self income had 1.74 (95% CI: 1.11-2.74 time increased risk than their counterparts. Maternal education was positively associated to zinc status. Grand multiparas were 1.74 (95% CI: 1.09-3.23 times more likely to be zinc deficient than nulliparas. Frequency of coffee intake was negatively association to serum zinc level. Positive association was noted between serum zinc and hemoglobin concentrations. Altitude, history of iron supplementation, maternal workload, physical access to health service, antenatal care and nutrition education were

    Platelets are implicated in the pathogenesis of various chronic diseases including cancer. The main objective of the present study was to determine if dietary fish oil and piroxicam, known modulators of colon tumorigenesis, effect transforming growth factor (TGF)-betas and cyclooxygenase (COX) isozymes in the platelets of colon tumor-bearing male F344 rats. TGF-betas and COXs are important in the development of chronic illnesses including colon cancer. Animals harboring preneoplastic colonic lesions were randomly allocated to a low fat diet (5% by weight--low corn oil, LFC) and three high fat diets (23% by weight--high corn oil, HFC; high corn oil containing 150-ppm piroxicam, HFC+P; and high fish oil, HFF) for 16 weeks. TGF-beta1, TGF-beta2, COX-1 and COX-2 protein levels were assessed in the platelets by Western blot analysis. Active TGF-beta1 (12.5 kDa) level was significantly lower in the platelets of the HFC+P group (p level was significantly lower in the platelets of the HFF group (p protein in the platelets. However a 29-kDa protein, potentially a precursor of TGF-beta2, was detected in the platelets of all the groups and was significantly lower in the HFC+P and HFF groups than in LFC and HFC (p level was significantly lower in the HFF group than the other three groups (p protein was detected in the platelets of all diet groups. Piroxicam in the presence of high corn oil (HFC+P) significantly lowered the level of COX-2 (p level. These findings conclusively show that LFC and HFC differ from HFF and HFC+P, and piroxicam differs from fish oil, in regulating the levels of TGF-betas and COX in the platelets. This supports the conjecture that the levels of bioactive constituents of the platelets are profoundly modulated by dietary lipids, which in turn could influence the pathogenesis of chronic illnesses.

    High blood pressure is increasing worldwide, disproportionately so in developing countries. Inadequate health care systems and adoption of unhealthy lifestyles have been linked to this emergent pattern. To better understand this trend, it is imperative we measure prevalence of hypertension, and examine specific risk factors, at a local level. This study provides a cross-sectional view of urban residents of Arusha City to determine prevalence and associated risk factors. Blood pressure was measured using a digital sphygmomanometer. Interviews were conducted using the WHO STEPwise survey questionnaire to assess lifestyle factors. Dietary intake information was collected by a standardized Food Frequency Questionnaire (FFQ). Descriptive statistics were used to analyze demographic characteristics. Means and standard deviations were calculated for continuous variables and percentages for categorical variables. Pearson's Chi Square (χ (2)) tests were used to determine significant risk factors for hypertension, and multivariate log binomial regression was used to reveal potential predictors of hypertension. Dietary patterns were analyzed by principal component analysis. Approximately 45% of the study population was found to be hypertensive. The mean arterial blood pressure (MABP) of the sample was 102.3 mmHg (SD = 18.3). Mean systolic and diastolic blood pressure were 136.3 (SD = 30.5) and 85.3 (SD = 16.1) mmHg, respectively. Through multivariate analysis, age and body mass index were found to be independently, positively, associated with hypertension. Adherence to 'healthy' dietary pattern was negatively independently associated with hypertension. With nearly half of participants being hypertensive, this study suggests that hypertension is a significant health risk in Arusha, Tanzania. Obesity, healthy diet, and age were found to be positively associated with hypertension risk. This study did not establish any significant association between increased blood

    Research about the prevalence of underweight and overweight/obesity in the Saudi Arabian female population is limited. The aim of the present study was to examine the dietary habits and the prevalence of underweight and overweight/obesity and associated factors among female university students. A cross-sectional study. A university centre for female students in south-western Saudi Arabia. The study involved 663 randomly selected female university students who self-reported their physical activities, nutritional habits and socio-economic factors. Multiple linear and logistic regression analyses were used to identify factors associated with the students' BMI, dietary variables, underweight and overweight/obesity. The majority of the university females were normal weight (56.9%), but a high prevalence of underweight (19.2%) and overweight/obesity (23.8%) occurred. Social factors significantly associated with BMI were the presence of obese parents and siblings as well as physical activity levels, marital status, number of sisters, father's level of education and more frequent intake of French fries/potato chips (>3 times/week). Several variables were found to correlate with dietary habits, underweight and overweight/obesity. Of special interest is the association between the number of siblings and the participants' BMI and dietary intake in both negative and positive ways. The findings of this research have implications for health promotion and prevention of malnutrition among college-aged females. Health-care providers and policy makers need to involve the whole family when promoting females' physical activity. The study serves as an evidence-based background for planning and implementation of interventions targeting improvement of highly educated populations' nutritional habits.

    Full Text Available Introduction: Parents and mothers develop an intense working life. They seek a place where they can care for their children safely during the time they go to their working hours. Due to the number of hours children spend in these institutions, one of the services offered is food, which provides at least one hot meal and two snacks, representing more than 50% of the food consumed daily. Objetive: The objective was to evaluate the relationship between anthropometric indicators and dietary factors in children 1 to 3 years attached to a private daycare center in Oaxaca City, Oaxaca, Mexico. Methods: For this evaluation weight and height were registered. Nutritional diagnosis was according to WHO percentiles, while dietary factors to meet a nutritional survey and 24-hour recall was applied. Results: 61% of children had normal weight and 39% presented malnutrition (malnutrition, overweight or obesity. Through a survey the three meals provided by the daycare center were analyzed obtaining an energy average of 637.2 kcal, 55% carbohydrates, 31% lipids and 14% protein. It was found that there is a relationship between the two variables (anthropometric and dietary factors; OR = 4.9. Conclusion: The times of food provided by the daycare center are inadequate in terms of energy and macronutrients for children 1 to 3 years old.

    A 44-year-old man who drove a motorcycle experienced a collision with the side of another motorcycle. Because he had sustained a high-energy injury to the spinal cord, he was transferred to our hospital. His circulation was unstable, and received tracheal intubation in addition to thoracostomy for the hemothorax. Whole-body computed tomography (CT) revealed multiple fractures, right hemopneumothorax with pulmonary contusion, and minor liver injury. After infusing 5000 mL of lactated Ringer's solution and 10 units of blood, his circulation remained unstable. On a repeat CT examination, the left atrium was found to be compressed by a posterior mediastinal hematoma induced by the fracture of the thoracic spine, and a diagnosis of shock induced by multiple factors, including hemorrhagic, neurogenic, and obstructive mechanisms, was made. After obtaining stable circulation and respirations, internal fixation of the extremities and extubation were performed on the 12th hospital day. Chest CT performed on the 27th day showed the disappearance of compression of the left atrium by the hematoma.

    Dietary fiber is a term that reflects a heterogeneous group of natural food sources, processed grains, and commercial supplements. Several forms of dietary fiber have been used as complementary or alternative agents in the management of manifestations of the metabolic syndrome, including obesity. Not surprisingly, there is a great variation in the biological efficacy of dietary fiber in the metabolic syndrome and body weight control. Diverse factors and mechanisms have been reported as mediators of the effects of dietary fiber on the metabolic syndrome and obesity. Among this array of mechanisms, the modulation of gastric sensorimotor influences appears to be crucial for the effects of dietary fiber but also quite variable. This report focuses on the role, mechanism of action, and benefits of different forms of fiber and supplements on obesity and the metabolic syndrome, glycemia, dyslipidemia, and cardiovascular risk and explores the effects of dietary fiber on gastric sensorimotor function and satiety in mediating these actions of dietary fiber.

    Despite the strong association between obesity and binge eating, limited research has examined the implications of binge eating on dietary adherence and psychological factors in ethnically diverse type 2 diabetes patients. This study investigated the prevalence of binge eating and its association with dietary adherence, glycemic control, and psychological factors among indigenous and non-indigenous type 2 diabetes patients in Chile. Participants were 387 indigenous (Mapuche) and non-indigenous (non-Mapuche) adults with type 2 diabetes. Self-report measures of binge eating, dietary adherence, diet self-efficacy, body image dissatisfaction, and psychological well-being were administered. Participants' weight, height, and glycemic control (HbA(1c)) were also obtained. Approximately 8 % of the type 2 diabetes patients reported binge eating. The prevalence among Mapuche patients was 4.9 %, and among non-Mapuche patients, it was 9.9 %. Compared to non-binge eaters, binge eating diabetes patients had greater body mass index values, consumed more high-fat foods, were less likely to adhere to their eating plan, and reported poorer body image and emotional well-being. Results of this study extend previous research by examining the co-occurrence of binge eating and type 2 diabetes as well as the associated dietary behaviors, glycemic control, and psychological factors among indigenous and non-indigenous patients in Chile. These findings may increase our understanding of the health challenges faced by indigenous populations from other countries and highlight the need for additional research that may inform interventions addressing binge eating in diverse patients with type 2 diabetes.

    Background: Examining diet as a whole using dietary patterns as exposures is a complementary method to using single food or nutrients in studies of diet and disease, but the generalizability of intake patterns across race, region, and gender in the United States has not been established. Objective: To employ rigorous statistical analysis to empirically derive dietary patterns in a large bi-racial, geographically diverse population and examine whether results are stable across population subgroups. Design: The present analysis utilized data from 21,636 participants in the Reasons for Geographic and Racial Differences in Stroke (REGARDS) study who completed the Block 98 food frequency questionnaire. We employed exploratory factor analysis and confirmatory factor analyses on 56 different food groups iteratively and examined differences by race, region, and sex to determine the optimal factor solution in our sample. Results: Five dietary patterns emerged: the “Convenience” pattern was characterized by mixed dishes; the “Plant-based” pattern by fruits, vegetables, and fish; the “Sweets/Fats” pattern by sweet snacks, desserts, and fats and oils; the “Southern” pattern by fried foods, organ meat, and sweetened beverages; and the “Alcohol/Salads” pattern by beer, wine, liquor, and salads. Differences were most pronounced in the Southern pattern with black participants, those residing in the Southeast, and participants not completing high school having the highest scores. Conclusion: Five meaningful dietary patterns emerged in the REGARDS study and showed strong congruence across race, sex, and region. Future research will examine associations between these patterns and health outcomes to better understand racial disparities in disease and inform prevention efforts. PMID:25988129

    Full Text Available The purpose of this cross-sectional study was to investigate the joint associations of physical activity level (PAL and dietary patterns in relation to cardiovascular disease (CVD risk factors among Chinese men. The study population consisted of 13 511 Chinese males aged 18-59 years from the 2002 China National Nutrition and Health Survey. Based on dietary data collected by a food frequency questionnaire, four dietary patterns were identified and labeled as "Green Water" (high consumption of rice, vegetables, seafood, pork, and poultry, "Yellow Earth" (high consumption of wheat flour products and starchy tubers, "New Affluent" (high consumption of animal sourced foods and soybean products, and "Western Adopter" (high consumption of animal sourced foods, cakes, and soft drinks. From the information collected by a 1-year physical activity questionnaire, PAL was calculated and classified into 4 categories: sedentary, low active, active, and very active. As compared with their counterparts from the New Affluent pattern, participants who followed the Green Water pattern had a lower likelihood of abdominal obesity (AO; 50.2%, hypertension (HT; 37.9%, hyperglycemia (HG; 41.5%, elevated triglyceride (ETG; 14.5%, low HDL (LHDL; 39.8%, and metabolic syndrome (MS; 51.9%. When compared to sedentary participants, the odds ratio of participants with very active PAL was 0.62 for AO, 0.85 for HT, 0.71 for HG, 0.76 for ETG, 0.74 for LHDL, and 0.58 for MS. Individuals who followed both very active PAL and the Green Water pattern had a lower likelihood of CVD risk factors (AO: 65.8%, HT: 39.1%, HG: 57.4%, ETG: 35.4%, LHDL: 56.1%, and MS: 75.0%, compared to their counterparts who followed both sedentary PAL and the New Affluent pattern. In addition, adherence to both healthy dietary pattern and very active PAL presented a remarkable potential for CVD risk factor prevention.

This study investigates the associations between BRAF and K-ras mutations and clinicopathological, lifestyle and dietary factors in colorectal cancers. Methods 186 adenocarcinomas and 16 adenomas from the EPIC Norfolk study were tested for BRAF and K-ras mutations. Diet and lifestyle data were collected prospectively using seven day food diaries. Results BRAF V600E mutation was found in 15.6% of colorectal cancers but at higher frequencies in cancers with proximal location, poor differentiation and microsatellite instability (MSI (all p K-ras mutation (mostly in codons 12 and 13 was found in 22.0% of colorectal cancers but at higher frequencies in cancers of more advanced Dukes' stage (p = 0.001, microsatellite stable (MSS status (p = 0.002 and in individuals with lower blood high-density lipoprotein concentrations (p = 0.04. Analysis of dietary factors demonstrated no link between BRAF mutation and any specific dietary constituent, however, K-ras mutation was found at higher frequencies in individuals with higher white meat consumption (p K-ras were observed at higher frequencies in individuals consuming lower amounts of fruit (p = 0.02. Conclusion These data support the model of BRAF and K-ras mutations arising in distinct colorectal cancer subsets associated with different clinicopathological and dietary factors, acting as mutually exclusive mechanisms of activation of the same signalling pathway.

  14. Vasoprotection by Dietary Supplements and Exercise: Role of TNFα Signaling

    Full Text Available Vascular dysfunction contributes to the pathogenesis of various cardiovascular diseases. Dietary supplements, including fish oil, dietary fibers, and various natural products, and exercise training exert vasoprotective effects. However, the mechanisms underlying the vasoprotective benefits of dietary supplements and physical activity demand extensive investigation. Accumulating evidence suggests that inflammatory cytokine tumor necrosis factor-alpha (TNFα plays a pivotal role in the dysregulation of macrovascular and microvascular function. TNFα induces vascular inflammation, monocyte adhesion to endothelial cells, vascular oxidative stress, apoptosis, and atherogenic response and participates in the regulation of thrombosis and coagulation through multiple signaling pathways involving NFκB, Sp1, activator protein 1, JNK, p38, STAT3, and so forth. Dietary supplements and exercise training decrease TNFα production and ameliorate TNFα-mediated pathological changes in vasculature. Thus, the inhibitory effects of dietary supplements and physical exercise on TNFα production and TNFα signaling may contribute to their vasoprotective properties.

    Diet and nutritional status have been shown to play pivotal roles in the occurrence of many chronic diseases. In this study, we examined the patterns of dietary habits and their relationships with risk factors for cardiovascular and chronic diseases in Hong Kong working populations. In April 2000, a 5-year territory-wide health promotion campaign supported by the Li Ka Shing Foundation was launched in Hong Kong by the Health InfoWorld of Hospital Authority. Between July 2000 and March 2002, 4841 Chinese subjects [2375 (49.1%) men and 2466 (50.9%) women, mean age: 42.4 +/- 8.9 years (median: 43.0 years, range: 17-83 years)] from the general working class were recruited. Subjects were randomly selected using computer generated codes according to the distribution of occupational groups. A dietary questionnaire was used to assess 6 core dietary habits: daily fruit intake, vegetable intake, fluid intake, sugary drinks, regularity of daily meals and number of dining out each day. Overall, men had a worse cardiovascular risk profile and less desirable dietary habits than women. Those who had more unhealthy dietary habits were more likely to be obese and current smokers. Using logistic regression analysis with the dietary habits as independent variables, we found that obesity, smoking and constipation were independently associated with various unhealthy dietary patterns. In conclusion, there were close associations between dietary habits and risk factors for cardiovascular diseases in Hong Kong. More effective community education about healthy lifestyle is required in Hong Kong.

    Nielsen, Martha G.

    2006-01-01

    The U.S. Geological Survey, in cooperation with the National Park Service, developed a hydrogeomorphic (HGM) classification system for wetlands greater than 0.4 hectares (ha) on Mt. Desert Island, Maine, and applied this classification using map-scale data to more than 1,200 mapped wetland units on the island. In addition, two hydrologic susceptibility factors were defined for a subset of these wetlands, using 11 variables derived from landscape-scale characteristics of the catchment areas of these wetlands. The hydrologic susceptibility factors, one related to the potential hydrologic pathways for contaminants and the other to the susceptibility of wetlands to disruptions in water supply from projected future changes in climate, were used to indicate which wetlands (greater than 1 ha) in Acadia National Park (ANP) may warrant further investigation or monitoring. The HGM classification system consists of 13 categories: Riverine-Upper Perennial, Riverine-Nonperennial, Riverine- Tidal, Depressional-Closed, Depressional-Semiclosed, Depressional-Open, Depressional-No Ground-Water Input, Mineral Soil Flat, Organic Soil Flat, Tidal Fringe, Lacustrine Fringe, Slope, and Hilltop/Upper Hillslope. A dichotomous key was developed to aid in the classification of wetlands. The National Wetland Inventory maps produced by the U.S. Fish and Wildlife Service provided the wetland mapping units used for this classification. On the basis of topographic map information and geographic information system (GIS) layers at a scale of 1:24,000 or larger, 1,202 wetland units were assigned a preliminary HGM classification. Two of the 13 HGM classes (Riverine-Tidal and Depressional-No Ground-Water Input) were not assigned to any wetlands because criteria for determining those classes are not available at that map scale, and must be determined by more site-specific information. Of the 1,202 wetland polygons classified, which cover 1,830 ha in ANP, 327 were classified as Slope, 258 were

    Full Text Available BACKGROUND: Psychological factors are known predictors of cardiovascular disease in many clinical settings, but data are lacking for HIV infection. We carried out a prospective cohort study to evaluate potential psychological predictors of preclinical and clinical vascular disease in HIV patients. METHODOLOGY/PRINCIPAL FINDINGS: HIV patients were consecutively enrolled. Demographics, viral and immune parameters and traditional cardiovascular predictors were considered; Intima-Media Thickness (c-IMT, continuous measure and Carotid Plaques (CPs, focal thickening ≥1.5 mm were investigated by B-mode ultrasonography; depressive symptoms by the Beck Depression Inventory (BDI-II, Type D personality (Distressed Personality or Type D by the DS14, alexithymia by the Toronto Alexithymia Scale (TAS-20. Vascular outcomes included transient ischemic attacks or stroke, acute coronary syndrome, myocardial or other organ infarction. We enrolled 232 HIV subjects, 73.9% males, aged 44.5±9.9 y, 38.2% with AIDS diagnosis, 18.3% untreated. Mean Nadir CD4 T-cell counts were 237.5±186.2/mmc. Of them, 224 (96.5% attended IMT measurements; 201 (86.6% attended both IMT assessment and psychological profiling. Mean follow-up was 782±308 days. Fifty-nine patients (29.4% had CPs at baseline. Nineteen patients (9.5% had ≥1 vascular event; 12 (6.0% died due to such events (n = 4 or any cause. At baseline cross-sectional multivariate analysis, increasing age, total cholesterol, current smoking and Alexithymia score≥50 were significantly associated with both increased cIMT (linear regression and CPs (logistic regression. At follow-up analysis, log-rank tests and Cox's regression revealed that only older age (p = 0.001, current smoking (p = 0.019 and alexithymia score≥50 (p = 0.013 were independently associated with vascular events. CONCLUSIONS/SIGNIFICANCE: In HIV-infected subjects, the Alexithymic trait emerges as a strong predictor of increased IMT, presence of CPs

    Diets high in fruit and vegetable consumption are associated with a decrease in chronic diseases. Dietary factors are linked to 4 of the 10 leading noncommunicable causes of death: cardiovascular disease, some cancers, stroke, and type 2 diabetes. Accurately measuring dietary patterns has many challenges. Dietary intake measurement has traditionally relied on self-report instruments such as 24-hour recall, food record, and food frequency questionnaires to record consumption history. These methods have inherent limitations in detecting small but important changes in fruit and vegetable consumption patterns. Promising advances in technology have made more sophisticated techniques for recording dietary intake possible. Computers and Web-based programs, handheld personal digital assistants with cameras and telephone cards, smart phones, cameras, and video recorders options may reduce the burden of recording what has been consumed. Furthermore, technology-based methods of dietary assessment may provide a higher degree of reliability and validity in visually determining fruit and vegetable consumption, and additional study is warranted. The purpose of this article is to present a review of the evidence on the effectiveness of technology-based methods for dietary assessment, which included fruit and vegetable consumption. One hundred and eighty-seven articles published between 1998 and 2008 were initially identified. Fifteen met the study inclusion criteria and were evaluated by an interdisciplinary team using the Stetler Strength of Evidence Scale. Six technology-based methods for dietary assessment were identified. Findings from validity and reliability testing of technology-based methods are encouraging and need replication. Clinically important features offered through technology may reduce reporting burden and offer behavioral feedback to users. Methodologically sound, empirical research into using technology-based application for dietary assessment in a variety of

    AIM: To study the main environmental and lifestyle factors that account for the regional differences in esophageal cancer (EC) risk in low- and high-risk areas of Jiangsu Province, China.METHODS: Since 2003, a population-based casecontrol study has been conducted simultaneously in lowrisk (Ganyu County) and high-risk (Dafeng County) areas of Jiangsu Province, China. Using identical protocols and pre-tested standardized questionnaire, following written informed consent, eligible subjects were inquired about their detail information on potential determinants of EC, including demographic information, socio-economic status, living conditions, disease history, family cancer history, smoking, alcohol drinking, dietary habits, frequency, amount of food intake, etc. Conditional logistic regression with maximum likelihood estimation was used to obtain Odds ratio (OR) and 95 % confidence interval (95% CI), after adjustment for potential confounders.RESULTS: In the preliminary analysis of the ongoing study, we recruited 291 pairs of cases and controls in Dafeng and 240 pairs of cases and controls in Ganyu,respectively. In both low-risk and high-risk areas, EC was inversely associated with socio-economic status, such as level of education, past economic status and body mass index. However, this disease was more frequent among those who had a family history of cancer or encountered misfortune in the past 10 years. EC was also more frequent among smokers, alcohol drinkers and fast eaters.Furthermore, there was a geographic variation of the associations between smoking, alcohol drinking and EC risk despite the similar prevalence of these risk factors in both low-risk and high-risk areas. The dose-response relationship of smoking and smoking related variables,such as age of the first smoking, duration and amount were apparent only in high-risk areas. On the contrary, a dose-response relationship on the effect of alcohol drinking on EC was observed only in low-risk areas

    In a previous paper we have pointed out that the common-translation-factor (CTF) method is the only one which, at present, and within the framework of the molecular model of atomic collisions, can be shown to be both convergent and computationally fast, even for many-electron systems. In this Communication we check that this second statement is correct, presenting, for the first time, a molecular calculation involving two-electron translation factors, for He/sup +/ + H collisions. A careful study of the sensitivity of the calculated cross sections to the choice of the CTF is performed, and conclusions on that sensitivity are drawn, for several types of processes.

    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.

    The change ΔR(x) of bond length R(x) for atom X in a molecule upon electronic transition can be derived from the intensities I(i) of the vibrational stretching progression v = 0 → i of the electronic absorption or emission spectrum. In many cases, a simple model is sufficient for a reasonable estimate of ΔR(x). For symmetric molecules, however, conceptual problems in the literature of many decades are evident. The breathing modes of various types of symmetric molecules X(n) and AX(n) (A at the center) are here discussed. In the simplest case of a harmonic vibration of the same mode in the initial and final electronic states, we obtain ΔR(x) ≈ [2S/(ωm(x))](1/2)/w(1/2) (all quantities in atomic units). ω and S are respectively the observed vibrational quanta and the Huang-Rhys factor (corresponding, e.g., to the vibrational intensity ratio I(1)/I(0) ≈ S), m(x) is the mass of vibrating atom X, and w is a topological factor for molecule X(n) or AX(n). The factor 1/w(1/2) in the expression for ΔR(x) must not be neglected. The spectra and bond length changes of several symmetric molecules AX(n) and X(n) are discussed.

    To ensure the protection of drinking water an understanding of the catchment processes which can affect water quality is important as it enables targeted catchment management actions to be implemented. In this study factor analysis (FA) and comparing event mean concentrations (EMCs) with baseline values were techniques used to asses the relationships between water quality parameters and linking those parameters to processes within an agricultural drinking water catchment. FA found that 55% of the variance in the water quality data could be explained by the first factor, which was dominated by parameters usually associated with erosion. Inclusion of pathogenic indicators in an additional FA showed that Enterococcus and Clostridium perfringens (C. perfringens) were also related to the erosion factor. Analysis of the EMCs found that most parameters were significantly higher during periods of rainfall runoff. This study shows that the most dominant processes in an agricultural catchment are surface runoff and erosion. It also shows that it is these processes which mobilise pathogenic indicators and are therefore most likely to influence the transport of pathogens. Catchment management efforts need to focus on reducing the effect of these processes on water quality.

    complications. A potential pathophysiological role of dietary AGEs in type 2 diabetes and cardiovascular disease has been discussed, as the contribution of dietary AGEs has been estimated to be larger than the amount of endogenously formed AGEs. Furthermore, the increased mortality associated with type 2...... diabetes and cardiovascular disease underlines the importance of identifying possible risk factors in the Western lifestyle. The overall aim of this thesis was to investigate if intake of dietary AGEs increases risk markers for type 2 diabetes and cardiovascular disease. In an acute meal study, effects...... sensitivity, and markers of inflammation and oxidative stress of dietary AGEs with different molecular size were investigated over 2 weeks. It was concluded that the diet with low molecular weight AGEs was most efficient in up-regulating expression of AGE receptors in whole blood, but no effects on insulin...

    In the field of autoimmune thyroiditis, NOD.H2(h4) mice have attracted significant and increasing attention since they not only develop spontaneous disease but they present thyroiditis with accelerated incidence and severity if they ingest iodide through their drinking water. This animal model highlights the interplay between genetic and dietary factors in the triggering of autoimmune disease and offers new opportunities to study immunoregulatory parameters influenced by both genes and environment. Here, we review experimental findings with this mouse model of thyroiditis.

    Full Text Available Genetic factors have a strong influence on obesity and are associated with body mass index (BMI. No study has investigated the relationships between glucose, the fat mass and obesity-associated (FTO gene, obesity (BMI, and other metabolic-related traits in Saudi Arabia. This study was conducted to identify the association between glucose, BMI and the FTO rs9939609 variant with different metabolic traits among 186 female preparatory students at Taibah University in 2015. The subjects were divided into two categories based on glucose level and BMI. The results showed that 1/10th of the students were non-obese, while approximately 1/3rd had a high glucose level (HGL. The HGL group had higher mean levels of glucose, cholesterol, triglycerides, HDL, LDL, VLDL, and malondialdehyde compared to those of the normal glucose level (NGL group. A highly positive correlation between glucose and some biochemical parameters was found in the HGL group (P  0.05 in the whole population (n = 186 in both obese and non-obese groups and both HGL and NGL groups. In conclusion, a positive correlation between glucose and some biochemical parameters was found in the HGL group; 24.5% of the population had the (A allele risk factor, and 32% and 98% of the population were homozygous (AA and heterozygous (AT for the rs9939609 FTO obesity-risk allele that is responsible for greater energy intake. Future studies are required to study the FTO gene variant and its association with different biochemical parameters, mainly glucose, weight, and BMI, between males and females at different ages and locations in Saudi Arabia.

    The role of dietary protein for the development of feline calcium oxalate (CaOx) uroliths has not been conclusively clarified. The present study evaluated the effects of a varying dietary protein concentration and quality on critical indices for the formation of CaOx uroliths. Three diets with a high protein quality (10-11 % greaves meal/diet) and a varying crude protein (CP) concentration (35, 44 and 57 % in DM) were compared. Additionally, the 57 % CP diet was compared with a fourth diet that had a similar CP concentration (55 % in DM), but a lower protein quality (34 % greaves meal/diet). The Ca and oxalate (Ox) concentrations were similar in all diets. A group of eight cats received the same diet at the same time. Each feeding period was divided into a 21 d adaptation period and a 7 d sampling period to collect urine. There were increases in urinary volume, urinary Ca concentrations, renal Ca and Ox excretion and urinary relative supersaturation (RSS) with CaOx with increasing dietary protein concentrations. Urinary pH ranged between 6·34 and 6·66 among all groups, with no unidirectional effect of dietary protein. Lower renal Ca excretion was observed when feeding the diet with the lower protein quality, however, the underlying mechanism needs further evaluation. In conclusion, although the observed higher urinary volume is beneficial, the increase in urinary Ca concentrations, renal Ca and Ox excretion and urinary RSS CaOx associated with a high-protein diet may be critical for the development of CaOx uroliths in cats.

    The Eating Disorder Inventory-2 Perfectionism subscale (EDI-P) was originally construed as a unidimensional measure of perfectionism. However, research in non-clinical samples suggests that the EDI-P measures two dimensions of perfectionism: self-oriented and socially prescribed perfectionism. This study aimed to investigate the factor structure of the EDI-P in a transdiagnostic sample of females seeking treatment for an eating disorder, and to determine the unique association between EDI-P dimensions, weight and shape concern, and dietary restraint in anorexia nervosa (AN), bulimia nervosa (BN), and eating disorder not otherwise specified. Two hundred and ninety nine females seeking treatment for an eating disorder at an outpatient eating disorder service completed the Eating Disorder Examination and the EDI-P. Confirmatory factor analysis supported a two-factor model of the EDI-P comprising self-oriented and socially prescribed perfectionism. Self-oriented perfectionism, but not socially prescribed perfectionism, accounted for unique variance in weight and shape concern and dietary restraint in both AN and BN. Results highlight the potential importance of self-oriented perfectionism in eating disorders and support the argument that self-imposed standards are central to perfectionism in eating disorders.

    Diabetes education programs need improved measures of goal setting for dietary control of diabetes. Additionally, measures of patient experiences with dietary goal setting are needed to better prepare patients for diabetes self-management. Measures of dietary goals and strategies were investigated via survey of 100 Mexican Americans and non-Hispanic whites with type 2 diabetes at a community clinic. Analyses tested novel goal measures as stages of change and goal attainment with a food plan compared to a traditional measure of food plan adherence. Ethnic groups varied in some reported experiences with goal setting education and goal attainment, but did not differ in most clinical characteristics of diabetes. Results indicated that different measures of goal setting vary in their psychosocial predictors, suggesting changes in how health care providers use and monitor goal setting for patients. At the time this research was conducted, Dr. Briggs Early was a doctoral candidate in the Department of Food Science and Human Nutrition at Washington State University. She is currently an Assistant Professor of Biochemistry and Nutrition at Pacific Northwest University of Health Sciences - College of Osteopathic Medicine, and a certified diabetes educator, and insulin pump trainer in Yakima, Washington.

    Little is known about the retinal cellular basis of amblyopia, which is a developmental disease characterized by impaired visual acuity. This study examined the retinal transcripts associated with experimentally induced unilateral amblyopia in rats. Surgical tarsorrhaphy of the eyelids on one side was performed in pups prior to eye opening at postnatal day 14, thereby preventing any visual experience. This condition was maintained for over 2 months, after which electroretinograms (ERGs) were recorded, the retinal ganglion cell (RGC) arrangement and number were determined using neuroanatomical tracing, the retinal transcripts were studied using microarray analysis, regulated mRNAs were confirmed with quantitative reverse-transcriptase PCR, and proteins were stained using Western blotting and immunohistochemistry. An attenuated ERG was found in eyes that were deprived of visual experience. Retrograde neuroanatomical staining disclosed a larger number of RGCs within the retina on the visually deprived side compared to the non-deprived, control side, and a multilayered distribution of RGCs. At the retinomic level, several transcripts associated with retinal differentiation, such as fibroblast growth factor 2 (FGF-2), were either up- or downregulated. Most of the transcripts could be verified at the mRNA level. To unravel the role of a differentiation-associated protein, we tested FGF-2 in dissociated postnatal retinal cell cultures and found that FGF-2 is a potent factor triggering ganglion cell differentiation. The data suggest that visual experience shapes the postnatal retinal differentiation, whereas visual deprivation induces changes at the functional, cellular and molecular levels within the retina.

    Although embryonic stem (ES) cell-like induced pluripotent stem (iPS) cells have potential therapeutic applications in humans, they are also useful for creating genetically modified human disease models in nonhuman primates. In this study, we generated common marmoset iPS cells from fetal liver cells via the retrovirus-mediated introduction of six human transcription factors: Oct-3/4, Sox2, Klf4, c-Myc, Nanog, and Lin28. Four to five weeks after introduction, several colonies resembling marmoset ES cells were observed and picked for further expansion in ES cell medium. Eight cell lines were established, and validation analyses of the marmoset iPS cells followed. We detected the expression of ES cell-specific surface markers. Reverse transcription-PCR showed that these iPS cells expressed endogenous Oct-3/4, Sox2, Klf4, c-Myc, Nanog and Lin28 genes, whereas all of the transgenes were silenced. Karyotype analysis showed that two of three iPS cell lines retained a normal karyotype after a 2-month culture. Both embryoid body and teratoma formation showed that marmoset iPS cells had the developmental potential to give rise to differentiated derivatives of all three primary germ layers. In summary, we generated marmoset iPS cells via the transduction of six transcription factors; this provides a powerful preclinical model for studies in regenerative medicine.

    Biomedical perspectives have long dominated research on the etiology and progression of Alzheimer's disease (AD); yet these approaches do not solely explain observed variations in individual AD trajectories. More robust biopsychosocial models regard the course of AD as a dialectical interplay of neuropathological and psychosocial influences. Drawing on this broader conceptualization, we conducted an extensive review of empirical and theoretical literature on the associations of trauma, posttraumatic stress disorder (PTSD) and AD to develop a working model that conceptualizes the role of psychosocial stressors and physiological mechanisms in the onset and course of AD. The proposed model suggests two pathways. In the first, previous life trauma acts as a risk factor for later-life onset of AD, either directly or mediated by PTSD or PTSD correlates. In the second, de novo AD experiential trauma is associated with accelerated cognitive decline, either directly or mediated through PTSD or PTSD correlates. Evidence synthesized in this paper indicates that previous life trauma and PTSD are strong candidates as psychosocial risk factors for AD and warrant further empirical scrutiny. Psychosocial and neurological-based intervention implications are discussed. A biopsychosocial approach has the capacity to enhance understanding of individual AD trajectories, moving the field toward 'person-centered' models of care.

    2017-05-01

    The Askaryan effect describes coherent electromagnetic radiation from high-energy cascades in dense media with a collective charge. We present an analytic model of Askaryan radiation that accounts simultaneously for the three-dimensional form factor of the cascade, and quantum mechanical cascade elongation via the Landau-Pomeranchuk-Migdal effect. These calculations, and the associated open-source code, allow the user to avoid computationally intensive Monte Carlo cascade simulations. Searches for cosmogenic neutrinos in Askaryan-based detectors benefit from computational speed, because scans of Askaryan parameter-space are required to match neutrino signals. The Askaryan field is derived from cascade equations verified with Geant4 simulations, and compared with prior numerical and semi-analytic calculations. Finally, instructive cases of the model are transformed from the Fourier domain to the time-domain. Next-generation in situ detectors like ARA and ARIANNA can use analytic time-domain signal models to search for correlations with event candidates.

  1. On defining dietary fibre.

    Science.gov (United States)

    DeVries, Jonathan W

    2003-02-01

    Establishing a definition for dietary fibre has historically been a balance between nutrition knowledge and analytical method capabilities. While the most widely accepted physiologically-based definitions have generally been accurate in defining the dietary fibre in foods, scientists and regulators have tended, in practice, to rely on analytical procedures as the definitional basis in fact. As a result, incongruities between theory and practice have resulted in confusion regarding the components that make up dietary fibre. In November 1998 the president of the American Association of Cereal Chemists (AACC) appointed an expert scientific review committee and charged it with the task of reviewing and, if necessary, updating the definition of dietary fibre. The committee was further charged with assessing the state of analytical methodology and making recommendations relevant to the updated definition. After due deliberation, an updated definition of dietary fibre was delivered to the AACC Board of Directors for consideration and adoption (Anon, 2000; Jones 2000b). The updated definition includes the same food components as the historical working definition used for approximately 30 years (a very important point, considering that the majority of the research of the past 30 years delineating the positive health effects of dietary fibre is based on that working definition). However, the updated definition more clearly delineates the make-up of dietary fibre and its physiological functionality. As a result, relatively few changes will be necessary in analytical methodology. Current methodologies, in particular AACC-approved method of analysis 32-05 (Grami, 2000), Association of Official Analytical Chemists' official method of analysis 985.29 (Horwitz, 2000a) or AACC 32-07 (Grami, 2000) Association of Official Analytical Chemists 991.43 (Horwitz, 2000a) will continue to be sufficient and used for most foods. A small number of additional methods will be necessary to

    Observational studies suggest an association between dietary fiber consumption and risk of stroke, but the results are inconclusive. The authors conducted a meta-analysis of prospective cohort studies to evaluate the relation between dietary fiber consumption and stroke risk and mortality. Relevant studies were identified by searching PubMed, Embase, and ISI Web of Science through February 2013. We included prospective studies that reported relative risks (RRs) with 95 % confidence intervals (CIs) for the association between dietary fiber consumption and stroke risk and mortality. Both fixed- and random-effects models were used to calculate the summary risk estimates. Eleven prospective studies involving 325,627 participants were included in the meta-analysis. The pooled RR of stroke for the highest compared with the lowest dietary fiber consumption was 0.83 (95 % CI 0.74, 0.93). In addition, the increment in dietary fiber consumption was associated with decreased stroke risk in a dose-response manner. Sensitivity analysis restricted to studies with control for conventional risk factors yielded similar results, and omission of any single study had little effect on the combined risk estimate. Moreover, there was a trend toward an inverse association between higher fiber consumption and stroke mortality (RR 0.85; 95 % CI 0.60, 1.20), although it is not significant. This meta-analysis indicated that dietary fiber consumption is inversely associated with stroke risk, and the effect is probably independent of conventional risk factors. Our results support recommendations for higher consumption of fiber-rich foods to prevent stroke.

    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 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.

    Full Text Available Studies of obesity and related health conditions among the Bhutanese, one of the largest refugee groups resettled in the United States in the past five years, are limited. This study examined the factors associated with excess body weight (body mass index ≥ 23 kg/m2 and abdominal obesity (waist circumference > 80 cm in a community-based sample of 18–65 year old Bhutanese refugee women in Northeast Ohio. A Nepali-language questionnaire was used to measure socio-demographic and dietary factors. Height, weight, and waist circumference were measured to define excess body weight and abdominal obesity. The mean (±standard deviation age of the 108 participants was 36.5 (±12.2 years and length of time in the U.S. was 19.4 (±11.9 months. Overall, 64.8% and 69.4% of the women had excess body weight and abdominal obesity, respectively. Age was significantly associated with both excess body weight (odds ratio: 1.10; 95% confidence interval: 1.05–1.16 and abdominal obesity (1.09; 1.04–1.14. Consuming meat (4.01; 1.14–14.60 was significantly associated with excess body weight but not abdominal obesity. These findings suggest the need for lifestyle and dietary change education programs among this new and vulnerable group to reduce the prevalence of excess body weight and abdominal obesity and their health consequences.

    Full Text Available TRAIL is a promising candidate for cancer therapeutics that preferentially induces apoptosis in cancer cells. The combined treatment flavonoids with TRAIL might be promising as a chemoprevention and/or new therapy against malignant tumors. We examined the cytotoxic effect of dietary flavonoids in combination with TRAIL on HeLa cells. It was found that treatment with noncytotoxic concentration of some flavonoids significantly sensititizes to TRAIL induced death in HeLa cells. Our study demonstrated that flavone, apigenin and genistein markedly augmented TRAIL mediated cytotoxicity against HeLa, whereas kaempferol and quercetin produced no effect.

    The authors compared dietary pattern methods-cluster analysis, factor analysis, and index analysis-with colorectal cancer risk in the National Institutes of Health (NIH)-AARP Diet and Health Study (n = 492,306). Data from a 124-item food frequency questionnaire (1995-1996) were used to identify 4 clusters for men (3 clusters for women), 3 factors, and 4 indexes. Comparisons were made with adjusted relative risks and 95% confidence intervals, distributions of individuals in clusters by quintile of factor and index scores, and health behavior characteristics. During 5 years of follow-up through 2000, 3,110 colorectal cancer cases were ascertained. In men, the vegetables and fruits cluster, the fruits and vegetables factor, the fat-reduced/diet foods factor, and all indexes were associated with reduced risk; the meat and potatoes factor was associated with increased risk. In women, reduced risk was found with the Healthy Eating Index-2005 and increased risk with the meat and potatoes factor. For men, beneficial health characteristics were seen with all fruit/vegetable patterns, diet foods patterns, and indexes, while poorer health characteristics were found with meat patterns. For women, findings were similar except that poorer health characteristics were seen with diet foods patterns. Similarities were found across methods, suggesting basic qualities of healthy diets. Nonetheless, findings vary because each method answers a different question.

Lipoprotein associated phospholipase A2 (Lp-PLA2) is an independent marker of inflammation and atherosclerosis risk. To assess the impact of weight loss on metabolic markers of atherosclerosis including Lp-PLA2 we examined a group of Czech non-diabetic obese/overweight children exposed to a lifestyle intervention. Fourty unrelated overweight/obese non-diabetic Czech children (13.7 ± 2.1 years, average BMI at baseline 29.8 ± 2.6 kg/m2) underwent 4 weeks of lifestyle modification (reduction of energy intake to age matched optimum and supervised physical activity). Anthropometrical and biochemical variables were determined at baseline and after the intervention. Lp-PLA2 mass concentration was assessed using the ELISA kit. Wilcocson's rank test and Spearman's correlation were used for statistical analysis. A significant decrease of BMI and waist circumference was associated with significant changes of plasma lipoprotein and glycaemia levels. Mass concentration of Lp-PLA2 at the baseline was 402 ± 94 μg/ml, after the intervention 368 ± 105 μg/ml (p=0.008). Change in Lp-PLA2 was associated with triglyceride level decrease (p=0.009). Intensive lifestyle modification leading to body weight decrease results in significant changes of plasma lipoprotein levels and, also, a drop of Lp-PLA2 levels in paediatric obese patients. However, even after the intervention Lp-PLA2 concentrations in this patient group remain elevated suggesting possible increased atherosclerosis risk in later life. © 2011 Neuroendocrinology Letters

    Aside from exposure to ionizing radiation and benzene, little is known about lifestyle risk factors for chronic myeloid leukemia (CML) in the general population. We examined the relation between lifestyle and dietary risk factors for CML in 493,188 participants (294,271 males and 198,917 females) aged 50 to 71 years who completed a baseline questionnaire in the National Institutes of Health-AARP Diet and Health Study in 1995 to 1996. Over a median of 10.5 years of follow-up, 178 incident cases of CML (139 males and 39 females) were ascertained from state registries. We used Cox proportional hazards models to estimate hazard ratios and 95% confidence intervals for exposures of interest, adjusting for potential confounding variables. In multivariable analysis of all participants combined, female sex, years of education, and vigorous physical activity (HR for ≥3 times/week vs. <1 time/week 0.70; 95% CI, 0.49-0.99) were inversely associated with risk of CML, whereas smoking intensity (HR for smokers of ≥20 cigarettes per day vs. never smokers: 1.53; 95% CI, 1.03-2.27) and body mass (HR for BMI ≥ 30 vs. <25 kg/m(2) 1.46; 95% CI, 0.95-2.23) were associated with increased risk. A range of dietary factors was not associated with disease. This study adds to the sparse information about lifestyle factors, which affect the risk of CML in the general population. If these findings are confirmed, it would suggest that CML may be amenable to preventive strategies.

    The aim of this study was to determine whether dietary cholecalciferol affects the recruitment and growth of axial skeletal muscle fibers in first-feeding European sea bass. Larvae were fed diets containing 0.28 (VD-L, low dose), 0.69 (VD-C, control dose), or 3.00 (VD-H, high dose) mg cholecalciferol/kg from 9 to 44 d posthatching (dph). Larvae were sampled at 44 dph for quantification of somatic growth, muscle growth, and muscle growth dynamics and at 22 and 44 dph for the relative quantification of transcripts encoded by genes involved in myogenesis, cell proliferation, and muscle structure. The weight increase of the VD-L-fed larvae was less than that of the VD-H-fed group, whereas that of VD-C-fed larvae was intermediate. The level of expression of genes involved in cell proliferation (PCNA) and early myogenesis (Myf5) decreased between 22 and 44 dph, whereas that of the myogenic determination factor MyoD1 and that of genes involved in muscle structure and function (myosin heavy chain, myosin light chains 2 and 3) increased. Dietary cholecalciferol regulated Myf5, MyoD1, myogenin, and myosin heavy chain gene expression, with a gene-specific shape of response. The maximum hypertrophy of white muscle fibers was higher in larvae fed the VD-C and VD-H diets than in larvae fed the VD-L diet. White muscle hyperplasia was highly stimulated in VD-H-fed larvae compared to VD-L- and VD-C-fed ones. These findings demonstrate a dietary cholecalciferol effect on skeletal muscle growth mechanisms of a Teleost species.

    To investigate associations between dietary patterns, socio-demographic factors and anthropometric measurements in adult New Zealanders. Dietary patterns were identified using factor analysis in adults 15 years plus (n = 4657) using 24-h diet recall data from the 2008/09 New Zealand Adult Nutrition Survey. Multivariate regression was used to investigate associations between dietary patterns and age, gender and ethnicity. After controlling for demographic factors, associations between dietary patterns and food insecurity, deprivation, education, and smoking were investigated. Associations between dietary patterns and body mass index and waist circumference were examined adjusting for demographic factors, smoking and energy intake. Two dietary patterns were identified. 'Healthy' was characterised by breakfast cereal, low fat milk, soy and rice milk, soup and stock, yoghurt, bananas, apples, other fruit and tea, and low intakes of pies and pastries, potato chips, white bread, takeaway foods, soft drinks, beer and wine. 'Traditional' was characterised by beef, starchy vegetables, green vegetables, carrots, tomatoes, savoury sauces, regular milk, cream, sugar, tea and coffee, and was low in takeaway foods. The 'healthy' pattern was positively associated with age, female gender, New Zealand European or other ethnicity, and a secondary school qualification, and inversely associated with smoking, food insecurity, area deprivation, BMI and waist circumference. The 'traditional' pattern was positively associated with age, male gender, smoking, food insecurity and inversely associated with a secondary school qualification. A 'Healthy' dietary pattern was associated with higher socio-economic status and reduced adiposity, while the 'traditional' pattern was associated with lower socio-economic status.

    Zinc was selected as a priority micronutrient for EURRECA, because there is significant heterogeneity in the Dietary Reference Values (DRVs) across Europe. In addition, the prevalence of inadequate zinc intakes was thought to be high among all population groups worldwide, and the public health concern is considerable. In accordance with the EURRECA consortium principles and protocols, a series of literature reviews were undertaken in order to develop best practice guidelines for assessing dietary zinc intake and zinc status. These were incorporated into subsequent literature search strategies and protocols for studies investigating the relationships between zinc intake, status and health, as well as studies relating to the factorial approach (including bioavailability) for setting dietary recommendations. EMBASE (Ovid), Cochrane Library CENTRAL, and MEDLINE (Ovid) databases were searched for studies published up to February 2010 and collated into a series of Endnote databases that are available for the use of future DRV panels. Meta-analyses of data extracted from these publications were performed where possible in order to address specific questions relating to factors affecting dietary recommendations. This review has highlighted the need for more high quality studies to address gaps in current knowledge, in particular the continued search for a reliable biomarker of zinc status and the influence of genetic polymorphisms on individual dietary requirements. In addition, there is a need to further develop models of the effect of dietary inhibitors of zinc absorption and their impact on population dietary zinc requirements.

    Lifestyle modification, including diet, is a key strategy for prevention and regression of cardiovascular disease (CVD), a leading cause of death worldwide. Traditionally, the study of the relationship between diet and CVD has focused on the analysis of single nutrients, or foods, in relation to CVD risk. In part one of this review, we present current epidemiologic and clinical evidence on nutrition and cardiovascular health with regards to specific foods and nutrients aimed at preventing CVD. The Cochrane Library database between 2006 and 2012 was searched for studies on effects of dietary factors on cardiovascular health. Evidence is presented on soy protein, fats, fish, nuts, fruit, vegetables, electrolytes, vitamins, and carbohydrate including fibre, glycaemic index, and wholegrains. Evidence from specific foods underpins current dietary CVD prevention guidelines, that advise on replacing saturated with unsaturated fat, consuming carbohydrate foods that are wholegrain or of low glycaemic index, increased consumption of fruit, vegetables (particularly cruciferous), nuts, and oily fish. Other nutrients (such as soya protein, or reducing sodium intake) reduce CVD risk via favourable effects on disease contributors (such as LDL-cholesterol or blood pressure), but also infer/promote dietary change that impacts other nutrients (using less animal or processed foods, resulting in saturated fat reduction). The complexity and limitations of interpreting dietary epidemiologic studies is reviewed. With the general ineffectiveness of nutrient-based intervention, recently the shift has been towards the examination of associations between dietary patterns and cardiovascular health, which will be examined in the second part of this review.

    Multiple sclerosis (MS) is demyelization disease of central nervous system of unidentified causes. Analytic epidemiological research of 19 patients, clinically approved cases of MS and 25 controls, autochthonic inhabitants of town of Cabar, Croatia, the high-risk zone for the disease, was made. The research plan included case-control investigation--the "door to door" questionnaire--about nutrition habits. An odds ratio (OR) was calculated for all the factors which were more frequently found in the patients than in the controls, and vice versa. The variables that were connected with significant risk for MS in the town of Cabar included: alcohol consumption (p = 0.05), animal fats/dried meat products consumption (p = 0.007), nitrate salting (p = 0.03), strong spices (p = 0.007), mixed bread (p = 0.002), oat and oat products consumption (p = 0.0075). No connection was found with regular consumption of vegetables and fruit (p = 0.009), blue fresh fish (p = 0.028), other fresh fish (p = 0.03), freshwater fish (p = 0.002), canned fish (p = 0.004), dormouse meat (p = 0.007), air-dried meat products (p = 0.004) and using the water from water supply (p = 0.011). In the town of Cabar nutritional customs, primarily food rich in animal fats, alcohol-abuse, and oat consumption could have an influence on MS pathogenesis in genetically inclined individuals.

    New molecular targets and intervention strategies for breaking the obesity-pancreatic cancer link are urgently needed. Using relevant spontaneous and orthotopically transplanted murine models of pancreatic cancer, we tested the hypothesis that dietary energy balance modulation impacts pancreatic cancer development and progression through an insulin-like growth factor (IGF)-I-dependent mechanism. In LSL-Kras(G12D)/Pdx-1-Cre/Ink4a/Arf(lox/+) mice, calorie restriction versus overweight- or obesity-inducing diet regimens decreased serum IGF-I, tumoral Akt/mTOR signaling, pancreatic desmoplasia, and progression to pancreatic ductal adenocarcinoma (PDAC), and increased pancreatic tumor-free survival. Serum IGF-I, Akt/mTOR signaling, and orthotopically transplanted PDAC growth were decreased in liver-specific IGF-I-deficient mice (vs. wild-type mice), and rescued with IGF-I infusion. Thus, dietary energy balance modulation impacts spontaneous pancreatic tumorigenesis induced by mutant Kras and Ink4a deficiency, the most common genetic alterations in human pancreatic cancer. Furthermore, IGF-I and components of its downstream signaling pathway are promising mechanistic targets for breaking the obesity-pancreatic cancer link.

    The copper content of 225 food, 49 beverage and twelve potable water samples were determined using atomic absorption spectrometry (AAS). Analyses of NIST and BCR reference materials demonstrated the accuracy of this technique. The highest copper levels were found in dried fruit and legumes, followed by organ meats, molluscs and crustaceans, cephalopods, cereals and sausages, respectively. In cereals, legumes and fruit, copper levels increased significantly with increasing levels of protein and decreasing carbohydrate content (p < 0.001). In meat and meat by-products, copper concentrations found in organ meats were significantly higher (p < 0.01). In fresh fish products, copper levels in shellfish were significantly higher than those measured in fish (p < 0.001). In vegetables, the copper concentrations found in mushrooms were significantly higher (p < 0.005). Mean copper concentrations analysed in cheese were statistically higher than those determined in other dairy products (p < 0.01). In beverages, copper levels determined in rum and juices were significantly higher (p < 0.001). Beverages for which a vegetable component was directly used in their manufacturing process (juices, wines and beers) had statistically higher copper levels when compared with fresh drinks. The daily dietary intake (DDI) of copper in the Andalusian diet was 1979 mug day(-1) per person. Cereals, meat, meat by-products and vegetables are the food categories that are the main source of copper in the daily diet. Taking into account the dietary reference intakes and upper levels (900 and 10, 000 mug Cu day(-1) for healthy adults, respectively), the mean copper DDI found indicate that for most of healthy adult individuals from the area, no adverse effects occur in relation to copper nutrition (deficiency or toxicity). Potable waters supplied 53 mug day(-1), which constitutes on average 0.025% of the maximum tolerable daily intake of this element set by the Joint FAO/WHO Expert Committee.

    Dietary pattern (DP) analysis allows examination of the combined effects of nutrients and foods on the markers of CVD. Very few studies have examined these relationships during adolescence or young adulthood. Traditional CVD risk biomarkers were analysed in 12-15-year-olds (n 487; Young Hearts (YH)1) and again in the same individuals at 20-25 years of age (n 487; YH3). Based on 7 d diet histories, in the present study, DP analysis was performed using a posteriori principal component analysis for the YH3 cohort and the a priori Mediterranean Diet Score (MDS) was calculated for both YH1 and YH3 cohorts. In the a posteriori DP analysis, YH3 participants adhering most closely to the 'healthy' DP were found to have lower pulse wave velocity (PWV) and homocysteine concentrations, the 'sweet tooth' DP were found to have increased LDL concentrations, and decreased HDL concentrations, [corrected] the 'drinker/social' DP were found to have lower LDL and homocysteine concentrations, but exhibited a trend towards a higher TAG concentration, and finally the 'Western' DP were found to have elevated homocysteine and HDL concentrations. In the a priori dietary score analysis, YH3 participants adhering most closely to the Mediterranean diet were found to exhibit a trend towards a lower PWV. MDS did not track between YH1 and YH3, and nor was there a longitudinal relationship between the change in the MDS and the change in CVD risk biomarkers. In conclusion, cross-sectional analysis revealed that some associations between DP and CVD risk biomarkers were already evident in the young adult population, namely the association between the healthy DP (and the MDS) and PWV; however, no longitudinal associations were observed between these relatively short time periods.

    Full Text Available Dietary fi bre is a group of food components which is resistant to digestive enzymes and found mainly in cereals, fruits and vegetables. Dietary fi ber and whole grains contain a unique blend of bioactive components including resistant starches, vitamins, minerals, phytochemicals and antioxidants. Dietary fi ber which indigestible in human small intestinal, on the other hand digested completely or partially fermented in the large intestine, is examined in two groups: water-soluble and water insoluble organic compounds. Dietary fi ber can be separated into many different fractions. These fractions include arabinoxylan, inulin, pectin, bran, cellulose, β-glucan and resistant starch. Dietary fi bres compose the major component of products with low energy value that have had an increasing importance in recent years. Dietary fi bres also have technological and functional properties that can be used in the formulation of foods, as well as numerous benefi cial effects on human health. Dietary fi bre components organise functions of large intestine and have important physiological effects on glucose, lipid metabolism and mineral bioavailability. Today, dietary fi bers are known to be protective effect against certain gastrointestinal diseases, constipation, hemorrhoids, colon cancer, gastroesophageal refl ux disease, duodenal ulcer, diverticulitis, obesity, diabetes, stroke, hypertension and cardiovascular diseases. In this review the physicochemical and biological properties of dietary fi bers and their important implications on human health will be investigated.

    Navratri is one of the most common religious fasts observed among Hindus. A large number of people with diabetes follow Navratris fast irrespective of its health implications, often without proper education and medical advice. The quest for the scientific research on dietary advices for Hindu fasts including Navratris shows paucity of literature comparative to the dietary advices advocated during Ramadan. The eating and physical activity patterns during different fasts vary a lot depending up on social and cultural factors. Even eating pattern is not uniform among all persons following Navratris and is modified as per their region, local culture, and religious beliefs. Dietary advice during Navratris depends upon pattern of fasting, religious beliefs, and local sociocultural factors. In this review, efforts are made to provide pragmatic dietary advice for people with diabetes, modifications in the menus and cooking practices, and timings of the meals for successful blood glucose management during Navratris. This review will also help plan diet and physical activity advice for persons observing other fasts as well. PMID:28217524

    In the present study, we aimed to identify the changes or stability in the structure of dietary patterns and tracking, trends and factors related to the adherence to these dietary patterns in China from 1991 to 2009. We analysed dietary data collected during seven waves of the China Health and Nutrition Survey and included 9253 adults with complete dietary data for three or more waves. Dietary intake assessment was carried out over a 3 d period with 24 h recalls and a household food inventory. Using factor analysis in each wave, we found that the structure of the two dietary patterns identified remained stable over the studied period. The traditional southern dietary pattern was characterised by high intakes of rice, fresh leafy vegetables, low-fat red meat, pork, organ meats, poultry and fish/seafood and low intakes of wheat flour and maize/coarse grains and the modern high-wheat dietary pattern was characterised by high intakes of wheat buns/breads, cakes/cookies/pastries, deep-fried wheat, nuts/seeds, starchy root/tuber products, fruits, eggs/egg products, soya milk, animal-based milk and instant noodles/frozen dumplings. Temporal tracking (maintenance of a relative position over time) was higher for the traditional southern dietary pattern, whereas adherence to the modern high-wheat dietary pattern had an upward trend over time. Higher income, education and urbanicity levels were positively associated with both the dietary patterns, but the association became weaker in the later years. These results suggest that even in the context of rapid economic changes in China, the way people chose to combine their foods remained relatively stable. However, the increasing popularity of the modern high-wheat dietary pattern, a pattern associated with several energy-dense foods, is a cause of concern.

    Reduced signaling through the C. elegans insulin/IGF1 like tyrosine kinase receptor daf2 and dietary restriction via bacterial dilution are two well-characterized lifespan-extending interventions that operate in parallel or through (partially) independent mechanisms. Using accurate mass and time tag LCMS/MS quantitative proteomics we detected that the abundance of a large number of ribosomal subunits is decreased in response to dietary restriction as well as in the daf2(e1370) insulin/IGF1 receptor mutant. In addition, general protein synthesis levels in these long-lived worms are repressed. Surprisingly, ribosomal transcript levels were not correlated to actual protein abundance, suggesting that posttranscriptional regulation determines ribosome content. Proteomics also revealed increased presence of many structural muscle cell components in long-lived worms, which appears to result from prioritized preservation of muscle cell volume in nutrient-poor conditions or low insulin-like signaling. Activation of DAF16, but not diet-restriction, stimulates mRNA expression of muscle-related genes to prevent muscle atrophy. Important daf2 specific proteome changes include overexpression of aerobic metabolism enzymes and a general activation of stress responsive and immune defense systems, while increased abundance of many protein subunits of the proteasome core complex is a DR-specific characteristic.

    Evaluate the influence of a specific program of physical exercise on cardiovascular risk, quality of life and eating habits of menopausal women. Prospective, intervention study previous-after without control group for three months. 66 menopausal women were included. The intervention consisted of a structured diet and exercise program. Biochemical, anthropometric, dietary and life quality parameters were determined before and three months after surgery. After the intervention a decrease in weight (4.4±2,3kg) and BMI (1.83±0.84kg/m(2)) (p<.05) occurs. A decrease in SBP (p<.05) was also observed. The fasting glucose went down 13.75±11.11mg/dl and HbA1c fell by 0.19±0,12%, both with p<.05. The lipid profile follows a similar behavior, highlighting a decline of 8± 6.2mg/dl in LDL cholesterol values (p<.05). The score on the measured cardiovascular risk by the Framingham tables decreases by 3% postoperatively (p<.05). Regarding the quality of life, it is significantly improved in all analyzed areas. The application of a structured exercise and diet program improves close monitoring parameters associated with cardiovascular risk of the women studied. It also improves the quality of life and dietary habits. Copyright © 2016 SEH-LELHA. Publicado por Elsevier España, S.L.U. All rights reserved.

    To investigate the effect of Mn on antioxidant status and on the expressions of heat shock proteins/factors in tissues of laying broiler breeders subjected to heat challenge, we used a completely randomised design (n 6) with a factorial arrangement of 2 environmental temperatures (normal, 21±1°C, and high, 32±1°C)×3 dietary Mn treatments (a Mn-unsupplemented basal diet (CON), or a basal diet supplemented with 120 mg Mn/kg diet, either as inorganic Mn sulphate (iMn) or as organic Mn proteinate (oMn)). There were no interactions (P>0·10) between environmental temperature and dietary Mn in any of the measured indices. High temperature decreased (P<0·003) Mn content, and also tended (P=0·07) to decrease Cu Zn superoxide dismutase (CuZnSOD) activity in the liver and heart. However, an increased Mn superoxide dismutase (MnSOD) activity (P<0·05) and a slight increase in malondialdehyde level (P=0·06) were detected in breast muscle. Up-regulated (P<0·05) expressions of heat shock factor 1 (HSF1) and HSF3 mRNA and heat shock protein 70 (HSP70) mRNA and protein were found in all three tissues. Broiler breeders fed either iMn or oMn had higher tissue Mn content (P<0·0001), heart MnSOD and CuZnSOD activities (P<0·01) and breast muscle MnSOD protein levels (P<0·05), and lower (P<0·05) breast muscle HSP70 mRNA and protein levels compared with those fed CON. Broiler breeders fed oMn had higher (P<0·03) bone Mn content than those fed iMn. These results indicate that high temperature decreases Mn retention and increases HSP70, HSF1 and HSF3 expressions in the tissues of laying broiler breeders. Furthermore, dietary supplementation with Mn in either source may enhance the heart's antioxidant ability and inhibit the expression of HSP70 in breast muscle. Finally, the organic Mn appears to be more available than inorganic Mn for bone in laying broiler breeders regardless of environmental temperatures.

    Dietary fiber may decrease the risk of cardiovascular disease and associated risk factors. We examined trends in dietary fiber intake among diverse US adults between 1999 and 2010, and investigated associations between dietary fiber intake and cardiometabolic risks including metabolic syndrome, cardiovascular inflammation, and obesity. Our cross-sectional analysis included 23,168 men and nonpregnant women aged 20+ years from the 1999-2010 National Health and Nutrition Examination Survey. We used weighted multivariable logistic regression models to estimate predicted marginal risk ratios and 95% confidence intervals for the risks of having the metabolic syndrome, inflammation, and obesity associated with quintiles of dietary fiber intake. Consistently, dietary fiber intake remained below recommended adequate intake levels for total fiber defined by the Institute of Medicine. Mean dietary fiber intake averaged 15.7-17.0 g. Mexican Americans (18.8 g) consumed more fiber than non-Hispanic whites (16.3 g) and non-Hispanic blacks (13.1 g). Comparing the highest with the lowest quintiles of dietary fiber intake, adjusted predicted marginal risk ratios (95% confidence interval) for the metabolic syndrome, inflammation, and obesity were 0.78 (0.69-0.88), 0.66 (0.61-0.72), and 0.77 (0.71-0.84), respectively. Dietary fiber was associated with lower levels of inflammation within each racial and ethnic group, although statistically significant associations between dietary fiber and either obesity or metabolic syndrome were seen only among whites. Low dietary fiber intake from 1999-2010 in the US, and associations between higher dietary fiber and a lower prevalence of cardiometabolic risks suggest the need to develop new strategies and policies to increase dietary fiber intake.

    Background Dietary fiber may decrease the risk of cardiovascular disease and associated risk factors. We examined trends in dietary fiber intake among diverse US adults between 1999 and 2010, and investigated associations between dietary fiber intake and cardiometabolic risks including metabolic syndrome, cardiovascular inflammation, and obesity. Methods Our cross-sectional analysis included 23,168 men and non-pregnant women aged 20+ years from 1999–2010 National Health and Nutrition Examination Survey. We used weighted multivariable logistic regression models to estimate predicted marginal risk ratios and 95% confidence intervals (CIs) for the risks of having the metabolic syndrome, inflammation, and obesity associated with quintiles of dietary fiber intake. Results Dietary fiber intake remained consistently below recommended adequate intake levels for total fiber defined by the Institute of Medicine. Mean dietary fiber intake averaged 15.7g–17.0g. Mexican-Americans (18.8 g) consumed more fiber than non-Hispanic Whites (16.3 g) and non-Hispanic Blacks (13.1 g). Comparing the highest to lowest quintiles of dietary fiber intake, adjusted predicted marginal risk ratios (95% CI) for the metabolic syndrome, inflammation, and obesity were 0.78 (0.69–0.88), 0.66 (0.61–0.72), and 0.77 (0.71–0.84), respectively. Dietary fiber was associated with lower levels of inflammation within each racial and ethnic group, though statistically significant associations between dietary fiber and either obesity or metabolic syndrome were seen only among whites. Conclusions Low dietary fiber intake from 1999–2010 in the US, and associations between higher dietary fiber and a lower prevalence of cardiometabolic risks suggest the need to develop new strategies and policies to increase dietary fiber intake.

    Full Text Available Prostate cancer is the second most common cancer diagnosed world-wide; however, patients demonstrate exceptionally high survival rates. Many lifestyle factors, including obesity and diet, are considered risk factors for advanced prostate cancer. Dietary fat is a fundamental contributor to obesity and may be specifically important for prostate cancer patients. Prostate cancer treatment can result in changes in body composition, affecting quality of life for survivors by increasing the risk of co-morbidities, like cardiovascular disease and diabetes. We aim to examine dietary fat throughout the prostate cancer treatment trajectory, including risk, cancer development and survivorship. Focusing on one specific nutrient throughout the prostate cancer trajectory provides a unique perspective of dietary fat in prostate cancer and the mechanisms that may exacerbate prostate cancer risk, progression and recurrence. Through this approach, we noted that high intake of dietary fat, especially, high intake of animal and saturated fats, may be associated with increased prostate cancer risk. In contrast, a low-fat diet, specifically low in saturated fat, may be beneficial for prostate cancer survivors by reducing tumor angiogenesis and cancer recurrence. The insulin-like growth factor (IGF/Akt signaling pathway appears to be the key pathway moderating dietary fat intake and prostate cancer development and progression.

    Chronic kidney disease (CKD) patients and their clinicians seek ways to mitigate the risk of CKD progression and its associated complications. Emerging data suggest that dietary modifications may be beneficial adjuvant approaches to reducing the risk of adverse CKD outcomes. This review focuses on several different dietary patterns, including the Dietary Approaches to Stop Hypertension and Mediterranean diets, and their kidney health benefits. We discuss how healthful dietary patterns are lower in dietary acid load and how improving diet quality may slow the progression of CKD. We also discuss some barriers that may impede socially disadvantaged individuals from following healthful diets. Dietary patterns low in dietary acid load might slow the progression of CKD. Current evidence suggests that a reduction in dietary acid load could be beneficial in patients with CKD, but the supremacy of any particular diet is yet to be established. Additional randomized controlled dietary interventions among CKD patients are needed to inform evidence-based recommendations, which can be tailored to an individual's preferences and ability to access healthful foods. © 2016 S.

    The key dietary pattern other than dietary factors influencing obesity has been reported by several large epidemiological studies. This study was carried out between 2010 and 2012 including 1613 adult residents in Zhejiang Province. Dietary patterns were extracted by factor analysis based on 24-h dietary recall. Associations with dietary patterns and obesity were examined and adjusted for age and gender by logistic regression. Five dietary patterns were identified by factor analysis with their eigenvalues greater than 1: 'cereal, animal, and plant food', 'high protein food', 'plant food', 'poultry', and 'beverage'. After adjustment for age and gender, the 'cereal, animal, and plant food' and 'beverage' pattern was associated with obesity (OR = 2.924, 3.257; 95% CI = 1.147-7.463, 1.372-7.692). In conclusion, 'cereal, animal, and plant food' and 'beverage' dietary patterns may be associated with increased risk of obesity. 'Cereal, animal, and plant food' dietary patterns may be associated with increased risk of obesity resulting from increased total energy intake by increased protein and fat intake; while a 'beverage' dietary pattern may be associated with increased risk of obesity resulting from increased total energy intake by increased carbohydrate intake. The findings are valuable in targeting future nutrition education.

    Undernutrition and non-communicable disease (NCD) are important public health issues in India, yet their relationship with dietary patterns is poorly understood. The current study identified distinct dietary patterns and their association with micronutrient undernutrition (Ca, Fe, Zn) and NCD risk factors (underweight, obesity, waist:hip ratio, hypertension, total:HDL cholesterol, diabetes). Data were from the cross-sectional Indian Migration Study, including semi-quantitative FFQ. Distinct dietary patterns were identified using finite mixture modelling; associations with NCD risk factors were assessed using mixed-effects logistic regression models. India. Migrant factory workers, their rural-dwelling siblings and urban non-migrants. Participants (7067 adults) resided mainly in Karnataka, Andhra Pradesh, Maharashtra and Uttar Pradesh. Five distinct, regionally distributed, dietary patterns were identified, with rice-based patterns in the south and wheat-based patterns in the north-west. A rice-based pattern characterised by low energy consumption and dietary diversity ('Rice & low diversity') was consumed predominantly by adults with little formal education in rural settings, while a rice-based pattern with high fruit consumption ('Rice & fruit') was consumed by more educated adults in urban settings. Dietary patterns met WHO macronutrient recommendations, but some had low micronutrient contents. Dietary pattern membership was associated with several NCD risk factors. Five distinct dietary patterns were identified, supporting sub-national assessments of the implications of dietary patterns for various health, food system or environment outcomes.

    Scaling factors for Pulay's scaled quantum mechanical (SQM) scheme have been determined for four different widely used DFT functionals (PBE, B3LYP, B3PW91, and M06-2X) and for two basis sets (6-31++G** and aug-cc-pVTZ) by fitting computed results to 347 fundamental experimental vibrational frequencies of 33 molecules. Measurements in the gas phase and in solid argon matrices were used independently in the fitting procedure in order to provide a simple method of estimating matrix shifts. The accuracy of the new scaling factors is demonstrated on test molecules including hydrogen-bonded systems and molecules containing chlorine and sulfur atoms.

    The tumour suppressor APC is the most commonly altered gene in colorectal cancer (CRC). Genetic and epigenetic alterations of APC may therefore be associated with dietary and lifestyle risk factors for CRC. Analysis of APC mutations in the extended mutation cluster region (codons 1276-1556) and APC promoter 1A methylation was performed on 185 archival CRC samples collected from participants of the European Prospective Investigation into Cancer (EPIC)-Norfolk study, with the aim of relating these to high-quality seven-day dietary and lifestyle data collected prospectively. Truncating APC mutations (APC(+) ) and promoter 1A methylation (PM(+) ) were identified in 43% and 23% of CRCs analysed, respectively. Distal CRCs were more likely than proximal CRCs to be APC(+) or PM(+) (p = 0.04). APC(+) CRCs were more likely to be moderately/well differentiated and microsatellite stable than APC(-) CRCs (p = 0.05 and 0.03). APC(+) CRC cases consumed more alcohol than their counterparts (p = 0.01) and PM(+) CRC cases consumed lower levels of folate and fibre (p = 0.01 and 0.004). APC(+) or PM(+) CRC cases consumed higher levels of processed meat and iron from red meat and red meat products (p = 0.007 and 0.006). Specifically, CRC cases harbouring GC-to-AT transition mutations consumed higher levels of processed meat (35 versus 24 g/day, p = 0.04) and iron from red meat and red meat products (0.8 versus 0.6 mg/day, p = 0.05). In a logistic regression model adjusted for age, sex and cigarette-smoking status, each 19 g/day (1SD) increment increase in processed meat consumption was associated with cases with GC-to-AT mutations (OR 1.68, 95% CI 1.03-2.75). In conclusion, APC(+) and PM(+) CRCs may be influenced by diet and GC-to-AT mutations in APC are associated with processed meat consumption, suggesting a mechanistic link with dietary alkylating agents, such as N-nitroso compounds.

    We have investigated the presence of DNA damage in human mammary epithelial cells collected from healthy lactating mothers (age, 20-35 years) who were resident in the Istanbul area. Breast milk (10ml) was collected from 30 women between one and two weeks post-partum. Demographic information (parity, breast cancer, occupation, duration of residency in Istanbul, consumption of fish, beef and poultry) was also obtained. Milk samples were diluted 1:1 with RPMI 1640 medium and centrifuged to collect cells. The cells were re-suspended and cell viability was determined by use of 0.4% trypan blue. DNA damage was assessed by use of the comet assay (alkaline single-cell gel electrophoresis). Fifty cells per slide and two slides per sample were scored to evaluate DNA damage. The cells were visually classified into four categories on the basis of extent of migration: undamaged (UD), lightly damaged (LD), moderately damaged (MD) and highly damaged (HD). Total comet scores (TCS) were calculated as: 1× UD+2× LD+3× MD+4× HD. Exfoliated mammary cells of the donors showed high (TCS≥150a.u.), moderate and low DNA damage in 10 (33.3%), 8 (26.7%) and 12 (40%) mothers, respectively. There was no significant correlation between TCS for DNA damage and the duration of previous breastfeeding, parity or age. None of the mothers was vegetarian, smoker or on any medication. Meat and chicken consumption did not significantly correlate with the TCS values. Fish consumption was significantly correlated with TCS results (Spearman's rho=0.39, pmothers in Istanbul may be of dietary origin. Our experience also confirms that sampling breast milk from lactating mothers provides a valuable and non-invasive tool to study DNA damage in mammary cells. Copyright © 2012 Elsevier B.V.

    Chinese populations are known to be at risk for vitamin D deficiency, with some evidence that this is due to lack of exposure to sunlight. Vitamin D deficiency and/or low sun exposure have been associated with higher incidence of hypertension in Caucasians. Thus, we investigated these associations in a Chinese population with a high rate of hypertension. From a random household survey of 1410 residents aged ≥18 years, height, weight and blood pressure were measured and demographic, exercise and dietary data were collected, as well as estimated hours of sunlight exposure on weekdays and weekends (in winter and summer). Modifiable predictors of hypertension in these data were lack of sunlight exposure and low intake of fish as well as smoking, obesity and lack of exercise. When investigated in a linear model, sunlight exposure was negatively associated with hypertension (β=-0.072, pexposure per day compared to none was associated with less hypertension (OR=0.6, 95% CI: 0.4-0.8). Similarly, consuming either oily fish or seafood more than four times per week compared to less was also associated with less hypertension (oily fish (OR=0.4, 95% CI: 0.3-0.5); seafood consumption (OR=0.8, 95% CI: 0.7-0.9)). Having daily moderate physical activity compared to none was also associated with a lower risk of hypertension (OR=0.8, 95% CI: 0.7-0.9). In contrast, being obese compared to normal weight and having more than five pack-years of smoking compared to none were associated with a higher risk of hypertension (OR=4.6, 95% CI: 3.7-5.7; OR=1.4, 95% CI: 1.0-1.8, respectively). The major new findings of this study are that more sun exposure and high weekly fish consumption (especially oily fish) may be potentially modifiable independent factors for protecting against risk of hypertension in this population.

    Studies done on dietary fiber (DF) over the past five years are presented in this Review. The involvement of dietary fiber in the control of plasma glucose and lipid levels is now established. Two dietary fiber sources (soybean and fenugreek) were studied in our laboratory and are discussed herein. These sources were found to be potentially beneficial in the reduction of plasma glucose in non-insulin dependent diabetes mellitus subjects. They are shown to be acceptable by human subjects and are easy to use either in a mixture of milk products and in cooking. The mechanism by which dietary fiber alters the nutrient absorption is also discussed. The effect of DF on gastric emptying, transit time, adsorption and glucose transport may contribute to reducing plasma glucose and lipid levels. DF was found to be effective in controlling blood glucose and lipid levels of pregnant diabetic women. Dietary fiber may also be potentially beneficial in the reduction of exogenous insulin requirements in these subjects. However, increased consumption of DF may cause adverse side effects; the binding capabilities of fiber may affect nutrient availability, particularly that of minerals and prolonged and high DF dosage supplementation must be regarded cautiously. This is particularly true when recommending such a diet for pregnant or lactating women, children or subjects with nutritional disorders. Physiological effects of DF appear to depend heavily on the source and composition of fiber. Using a combination of DF from a variety of sources may reduce the actual mass of fiber required to obtain the desired metabolic effects and will result in a more palatable diet. Previously observed problems, such as excess flatus, diarrhea and mineral malabsorption would also be minimized.

Method Two hundred and two overweight and obese children were compared with 209 normal weight children with respect to take a questionnaire which included food intake estimation using food photographs. a 24 h dietary record and survey of dietary behavior and family environment. Results Overweight and obese children tended to consume larger meal size (P<0.05). higher intake of energy (P<0.05) and macronutrients (P<0.05) per day while vegetables consumption was less (P<0.05). The meal size which was reported by children themselves showed similar results as the 24 h dietary record. The multiple logistic regression indicated that lunch size (OR=1.003, P<0.05), dinner size (OR=1.002,P<0.05), food energy density of dinner (OR=2.260. P<0.05), and protein consumption (OR=1.027. P<0.05) were correlated with children's simple obesity. However, the differences of the total energy and fat intake between two groups was not significant after adjusting the genetic and environmental factors (P>0.05). Conclusion Large meal size and high intake of high-energy density food at a meal were the most important risk factors of children's obesity. Food photographs appeared to be successful for children to estimate the food intake. The

    The experiment was conducted to evaluate the effect of dietary biochar including vine-gar liquid (BIOV) on growth performance and blood characteristics of weanling pigs. 60 barrows were allotted to 5 dietary treatments. Pigs in 1 group were fed with basal diets, and 2,3,4,5 groups were fed with oxytetracycline, 1%, 2%, and 3% BIOV respectively. The results of 14-d experi-ment showed that compared with control group, dietary 1% BIOV increased ADG by 8.55%(P0.05). Dietary 1% BIOV significantly increased the lymphocyte ratio and IgG(P<0.05), also, it significantly reduced the concentration of BUN and cortisol. It is concluded that dietary 1% BIOV improves performance and has improvement on immune function and anti-stress. Dietary 3%BIOV might conduct negative effect on piglet.%本试验探讨饲粮添加生物炭和木醋混合物(BIOV)对断奶仔猪生长性能和血液生化指标的影响。将60头仔猪随机分为5组,第1组为对照组,饲喂基础饲粮,第2、3、4、5组在基础饲粮中分别添加0.05%土霉素、1%、2%和3%的BIOV,试验期14 d。结果表明,BIOV添加组中1% BIOV组仔猪ADG最高,比对照组提高8.55%(P<0.05),但显著低于抗生素组(P<0.05)。3% BIOV组ADG较对照组降低1.68%(P>0.05)。1% BIOV能显著提高仔猪外周血淋巴细胞比率和IgG水平(P<0.05),显著降低血液皮质醇和尿素氮浓度(P<0.05)。由此可见,本试验14 d条件下,1% BIOV能促进仔猪生长,对仔猪免疫功能和抗应激能力有一定的促进作用,且3% BIOV添加量可能对仔猪生长有副作用。

  16. Using Short Dietary Questions to Develop Indicators of Dietary Behaviour for Use in Surveys Exploring Attitudinal and/or Behavioural Aspects of Dietary Choices

    Full Text Available For countries where nutrition surveys are infrequent, there is a need to have some measure of healthful eating to plan and evaluate interventions. This study shows how it is possible to develop healthful eating indicators based on dietary guidelines from a cross sectional population survey. Adults 18 to 64 years answered questions about the type and amount of foods eaten the previous day, including fruit, vegetables, cereals, dairy, fish or meat and fluids. Scores were based on serves and types of food according to an established method. Factor analysis indicated two factors, confirmed by structural equation modeling: a recommended food healthful eating indicator (RF_HEI and a discretionary food healthful eating indicator (DF_HEI. Both yield mean scores similar to an established dietary index validated against nutrient intake. Significant associations for the RF_HEI were education, income, ability to save, and attitude toward diet; and for the DF_HEI, gender, not living alone, living in a socially disadvantaged area, and attitude toward diet. The results confirm that short dietary questions can be used to develop healthful eating indicators against dietary recommendations. This will enable the exploration of dietary behaviours for “at risk” groups, such as those with excess weight, leading to more relevant interventions for populations.

    It has been well acknowledged that Vietnam is undergoing a nutrition transition. With a rapid change in the country's reform and economic growth, food supply at the macronutrient level has improved. Changes of the Vietnamese diet include significantly more foods of animal origin, and an increase of fat/oils, and ripe fruits. Consequently, nutritional problems in Vietnam now include not only malnutrition but also overweight/obesity, metabolic syndrome and other chronic diseases related to nutrition and lifestyles. The recognition of these shifts, which is also associated with morbidity and mortality, was a major factor in the need to review and update the Recommended Dietary Allowances (RDA) for the Vietnamese population. This revised RDA established an important science-based tool for evaluation of nutrition adequacy, for teaching, and for scientific communications within Vietnam. It is expected that the 2007 Vietnam RDA and its conversion to food-based dietary guidelines will facilitate education to the public, as well as the policy implementation of programs for prevention of non-communicable chronic diseases and addressing the double burden of both under and over nutrition.

    Gene-diet interaction using a multifactorial approach is preferred to study the multiple risk factors of cardiovascular disease (CVD). This study examined the association and gene-diet interaction effects of the angiotensin II type 1 receptor (AGTR1) gene (rs5186), and type 2 receptor (AGTR2) gene (rs1403543) polymorphisms on metabolic risk factors of CVD in Malaysian adults. CVD parameters (BMI, blood pressure, glycated hemoglobin, total cholesterol (TC), triglycerides, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol (HDL-C), and TC/HDL-C ratio), and constructed dietary patterns "vegetables, fruits, and soy diet" (VFSD), and "rice, egg, and fish diet" (REFD) were obtained from previous studies. Genotyping analysis was performed by real-time PCR using Taqman probes. The subjects were 507 adults (151 Malays; 179 Chinese; and 177 Indians). Significant genetic associations were obtained on blood lipids for rs5186 in Malays and Chinese, and rs1403543 in Chinese females. The significant gene-diet interaction effects after adjusting for potential confounders were: rs5186 × VFSD on blood pressure in Malays (p = 0.016), and in Chinese on blood lipids for rs5186 × REFD (p = 0.009-0.023), and rs1403543 × VFSD in female subjects (p = 0.001-0.011). Malays and Chinese showed higher risk for blood pressure and/or lipids involving rs5186 and rs1403543 SNPs together with gene-diet interactions, but not Indians.

    The purpose of this study was to clarify psychosocial characteristics associated with preventive health behavior for lifestyle-related diseases. The author performed objective health examinations and gave questionnaires to 289 men (39.7 +/- 11.8 years, mean +/- SD) and 80 women (32.8 +/- 10.4 years) engaged in office work. Psychosocial factors included lifestyle and perceived stress, as well as the health locus of control (HLC) and sense of coherence (SOC) as newly developed indicators for health behavior. The principal component analysis for men did not extract lifestyle from the psychosocial structures. Multiple regression analysis showed that internal HLC (IHLC), chance HLC (CHLC), professional HLC (PHLC) and stress significantly contributed to SOC. Principal component analysis using psychosocial factors in women showed two psychosocial structures, i.e. the second principal (high SOC, high lifestyle, and low stress) and the 4th principal components (high supernatural HLC, and high PHLC). Both components were negatively correlated with systolic blood pressure. SOC was recognized to be negatively associated with age, stress, and total cholesterol, and positively with IHLC, FHLC, lifestyle, and gamma-GTP using multiple regression analysis for women. These results indicated a distinguishable sex difference regarding the involvement of psychosocial factors including HLC and SOC in objective health. SOC seems likely to be involved not in objective health, but closely with stress, suggesting a direct influence on mental health. Lifestyle should be divided into more detailed categories such as smoking and salt intake. Structural analysis of women suggests that SOC is involved directly or indirectly through lifestyle in objective health, different from men. To further clarify causal relationships between psychosocial factors and risk factors for lifestyle-related diseases, a longitudinal study is necessary based on these results.

    Through cultural innovation and changes in habitat and ecology, there have been a number of major dietary shifts in human evolution, including meat eating, cooking, and those associated with plant and animal domestication. The identification of signatures of adaptations to such dietary changes in the genome of extant primates (including humans) may shed light not only on the evolutionary history of our species, but also on the mechanisms that underlie common metabolic diseases in modern human...

    The 2013 Institute of Medicine (IOM) report "Sodium Intake in Populations: Assessment of Evidence" did not support the current recommendations of the IOM and the American Heart Association (AHA) to reduce daily dietary sodium intake to below 2,300 mg. The report concluded that the population...... Control (CDC), other public health advisory bodies, and major medical journals have continued to support the current policy of reducing dietary sodium.......-based health outcome evidence was not sufficient to define a safe upper intake level for sodium.

    Polycomb and trithorax group genes maintain the appropriate repressed or activated state of homeotic gene expression throughout Drosophila melanogaster development. We have previously identified the batman gene as a Polycomb group candidate since its function is necessary for the repression of Sex combs reduced. However, our present genetic analysis indicates functions of batman in both activation and repression of homeotic genes. The 127-amino-acid Batman protein is almost reduced to a BTB/POZ domain, an evolutionary conserved protein-protein interaction domain found in a large protein family. We show that this domain is involved in the interaction between Batman and the DNA binding GAGA factor encoded by the Trithorax-like gene. The GAGA factor and Batman codistribute on polytene chromosomes, coimmunoprecipitate from nuclear embryonic and larval extracts, and interact in the yeast two-hybrid assay. Batman, together with the GAGA factor, binds to MHS-70, a 70-bp fragment of the bithoraxoid Polycomb response element. This binding, like that of the GAGA factor, requires the presence of d(GA)n sequences. Together, our results suggest that batman belongs to a subset of the Polycomb/trithorax group of genes that includes Trithorax-like, whose products are involved in both activation and repression of homeotic genes.

    Ketogenic dietary therapies are an effective treatment for children with drug-resistant epilepsy. There is currently no high-quality evidence regarding ketogenic dietary therapies in adults, and further research has been recommended. This audit aimed to provide further evidence for the feasibility of dietary treatment for adults and to consider factors that may aid response classification in this population. We evaluated the effectiveness and tolerability of ketogenic dietary therapies in 23 adults with epilepsy attending specialist clinics. Medical notes were used to obtain seizure frequency information and other effects associated with dietary treatment. Individuals who achieved ≥50% seizure reduction at all follow-up points were classified as responders. Response rates, in terms of seizure frequency, were similar to those commonly reported in pediatric cohorts: 9/23 (39%) adults were classified as responders. These responders remained on the diet for at least one year (follow-up: 1-10 years). Other benefits reported by patients, but not quantified, included a reduction in seizure severity and increased alertness and concentration. Such factors often favor continuation of ketogenic dietary therapies despite a ketogenic dietary therapies long-term, and such treatment can lead to seizure reduction. Other aspects besides seizure frequency may be relevant when classifying response in adults, and appropriat
