Access to foods and beverages on school campuses, at home, and other locations affects children's diet quality, energy intake, and risk of obesity. To describe patterns of consumption of "empty calories"--low-nutrient, energy-dense foods, including sugar-sweetened beverages--by eating location among National School Lunch Program (NSLP) participants and nonparticipants. Cross-sectional study using 24-hour dietary recall data from the 2004-2005 third School Nutrition Dietary Assessment Study. A nationally representative sample of 2,314 children in grades one through 12, including 1,386 NSLP participants. Comparisons, using t tests, of the proportion of children consuming low-nutrient, energy-dense foods and beverages, mean daily energy and energy from low-nutrient, energy-dense foods, and energy density by NSLP participation status. On a typical school day, children consumed 527 "empty calories" during a 24-hour period. Eating at home provided the highest mean amount of energy from low-nutrient, energy-dense foods (276 kcal vs 174 kcal at school and 78 kcal at other locations). NSLP participants consumed less energy from sugar-sweetened beverages at school than nonparticipants (11 kcal vs 39 kcal in elementary schools and 45 kcal vs 61 kcal in secondary schools, Pkcal vs 127 kcal, Plunch participants' consumption at school was less energy-dense than nonparticipants' consumption at school (Pdaily and energy from low-nutrient, energy-dense foods are consumed (especially from sugar-sweetened beverages, chips, and baked goods) is warranted. At schools, consumption of energy from low-nutrient, energy-dense foods may be reduced by limiting access to competitive foods and beverages, enforcing strong school wellness policies, and minimizing the frequency of offering french fries and similar potato products and higher-fat baked goods in school meals or à la carte.

Patterns of beverage consumption among children and adolescents can be indicative of food choices and total diet quality. Analyses of beverage consumption patterns among 8119 children aged 4-19 y were based on the first 24-h recall of the National Health and Nutrition Examination Survey (2009-14 NHANES). Four pre-defined beverage patterns were: 1) milk pattern; 2) 100% juice pattern; 3) milk and 100% juice pattern; and 4) other caloric beverages. Food- and nutrient-based diet quality measures included the Healthy Eating Index 2010. Most children drank other caloric beverages, as opposed to milk (17.8%), 100% juice (5.6%), or milk and 100% juice (13.5%). Drinkers of milk and 100% juice had diets that did not differ from each other in total calories, total and added sugars, fiber, or vitamin E. Milk drinkers consumed more dairy and had higher intakes of calcium, potassium, vitamin A and vitamin D as compared to all other patterns. Juice drinkers consumed more total fruit, same amounts of whole fruit, and had higher intakes of vitamin C as compared to the other consumption patterns. Drinkers of both milk and 100% juice had the highest HEI 2010 scores of all the consumption patterns. Beverage consumption patterns built around milk and/or 100% juice were relatively uncommon. Promoting the drinking of milk and 100% juice, in preference to other caloric beverages, may be an effective strategy to improve children's diet quality. Restricting milk and 100% juice consumption may encourage the selection of other caloric beverages.

by higher consumption of take away food, meat, confectionary and soft drinks ('western' and 'traditional and western') were found particularly among 16- to 17-years old boys and among adolescents with lower SES. These patterns were also associated with higher energy density, higher percent of energy from unsaturated fatty acids and lower percent of energy from carbohydrates as well as lower nutrient densities of several vitamins and minerals. Therefore, nutritional interventions should try to focus more on adolescents with lower SES and boys in general. PMID:22439777

Adolescence is a critical time for the establishment of healthy eating habits. The objective was to analyze food consumption patterns among adolescents and their relationship with family and social factors. Multicentre observational cross-sectional descriptive study using a food frequency questionnaire for the last week. It was answered anonymously. The adolescent's age/gender, parents' studies/occupation and school's location/type were included. The population sample was composed of 1,095 adolescents in sixth grade at primary schools from an Andalusian region. They were chosen by polietapic random sampling that distinguished between public/private and capital/provincial schools. 1,005 surveys were analyzed. The mean age is 11.45 (SD: 0.59). Fifty-three percent were male. The intake of dairy products (only two-thirds taken daily), pasta, fruit and vegetables (daily consumption of 30%) is deficient. Sixty-four point five percent consume legumes weekly. Fish consumption is equal to meat, with a preference for poultry. More than half consume red meat daily. Olive oil is preferred. The intake of "empty calories" (fast food, candies, soft drink) is high. Through multivariate analysis the existence of clusters of healthy and unhealthy foods, related to the social status of the parents and the type of school, is proved. A healthy diet based on the nutritional pyramid is not the consumption pattern in the adolescents surveyed. There is a low consumption of diary products, legumes, fruits and vegetables. There is a relationship between the social class of the family and consumption patterns (healthy and unhealthy). Health strategies are needed to modify such inappropriate consumption.

In Japan, in comparison with the rest of the world the death rate of lung cancer is low although the smoking rate is relatively high. This is the so-called "Japanese smoking paradox". A healthy diet is proposed to attenuate the risk without quitting smoking. We here examined the relationships between smoking status (SS) and the consumption of food and nutrient in Japan. Totals of 5,587 men and 2,718 women were divided into three (non-smokers, smokers and heavy smokers) and two (non-smokers and smokers) groups, respectively, according to pack-year, which represents the amount of smoking over a long period. Food and nutrient consumption was estimated with a validated food frequency questionnaire. Using general linear models, food and nutrient consumption was estimated for each group in men and women, separately. In men, SS was positively related to consumption of rice, 3 alcoholic beverages, carbohydrate, alcohol and other 8 foods/nutrients (p<0.05 for all) and negatively to those of protein animal, fat, fatty acids, dietary fiber, isoflavones and 36 other foods/nutrients (p<0.05 for all). In women, SS was positively associated with intake of 13 foods/nutrients, while being negatively associated with those of rice, energy, dietary fiber, and 14 other foods/nutrients (p<0.05 for all). Our results support lower intake of vegetables and fruits rich in antioxidants, which are thought as preventive factors for many diseases, in smokers.

Nutrient density of beverages in relation to climate impact

Full Text Available The food chain contributes to a substantial part of greenhouse gas (GHG emissions and growing evidence points to the urgent need to reduce GHGs emissions worldwide. Among suggestions were proposals to alter food consumption patterns by replacing animal foods with more plant-based foods. However, the nutritional dimensions of changing consumption patterns to lower GHG emissions still remains relatively unexplored. This study is the first to estimate the composite nutrient density, expressed as percentage of Nordic Nutrition Recommendations (NNR for 21 essential nutrients, in relation to cost in GHG emissions of the production from a life cycle perspective, expressed in grams of CO2-equivalents, using an index called the Nutrient Density to Climate Impact (NDCI index. The NDCI index was calculated for milk, soft drink, orange juice, beer, wine, bottled carbonated water, soy drink, and oat drink. Due to low-nutrient density, the NDCI index was 0 for carbonated water, soft drink, and beer and below 0.1 for red wine and oat drink. The NDCI index was similar for orange juice (0.28 and soy drink (0.25. Due to a very high-nutrient density, the NDCI index for milk was substantially higher (0.54 than for the other beverages. Future discussion on how changes in food consumption patterns might help avert climate change need to take both GHG emission and nutrient density of foods and beverages into account.

Beverages may be important contributors for energy intake and dietary quality. The purpose of the study was to investigate how beverage consumption varies between different meals (breakfast, lunch, dinner, supper/evening meal, snacks) and between weekdays and weekend-days in Norwegian adults. A cross-sectional dietary survey was conducted among Norwegian adults (n = 1787) in 2010-2011. Two telephone-administered 24 h recalls were used for dietary data collection. Breakfast was the most important meal for milk and juice consumption, dinner for sugar-sweetened beverages and wine, and snacks for water, coffee, artificially sweetened beverages, and beer. Consumption of sugar-sweetened and artificially sweetened beverages did not differ between weekdays and weekend-days among consumers. The average intake of wine and beer (men only) was higher on weekend-days. Higher age was positively associated with wine consumption and negatively associated with consumption of water, sugar-sweetened, and artificially sweetened beverages. Higher education was associated with consumption of water, beer, and wine, whereas lower education was associated with sugar-sweetened beverage consumption. Beverage consumption patterns among Norwegian adults vary between different meal types and in subgroups of the population. Alcohol consumption was higher on weekend-days. Knowledge regarding beverage consumption patterns in the population should be considered when revising dietary guidelines in the future.

Full Text Available Dietary or nutrient patterns represent the combined effects of foods or nutrients, and elucidate efficaciously the impact of diet on diseases. Because the pharmacotherapy on attention deficit hyperactivity disorder (ADHD was reported be associated with certain side effects, and the etiology of ADHD is multifactorial, this study investigated the association of dietary and nutrient patterns with the risk of ADHD. We conducted a case-control study with 592 Chinese children including ADHD (n = 296 and non-ADHD (n = 296 aged 6–14 years old, matched by age and sex. Dietary and nutrient patterns were identified using factor analysis and a food frequency questionnaire. Blood essential elements levels were measured using atomic absorption spectrometry. A fish-white meat dietary pattern rich in shellfish, deep water fish, white meat, freshwater fish, organ meat and fungi and algae was inversely associated with ADHD (p = 0.006. Further analysis found that a mineral-protein nutrient pattern rich in zinc, protein, phosphorus, selenium, calcium and riboflavin was inversely associated with ADHD (p = 0.014. Additionally, the blood zinc was also negatively related to ADHD (p = 0.003. In conclusion, the fish-white meat dietary pattern and mineral-protein nutrient pattern may have beneficial effects on ADHD in Chinese children, and blood zinc may be helpful in distinguishing ADHD in Chinese children.

DeYoung and Menzie (1999) examined the relations among population, Gross Domestic Product, and mineral consumption (aluminum, cement, copper, and salt) for Japan, Korea, and the United States between 1965 and 1995. They noted the extremely rapid growth of consumption in Korea between 1975 and 1995. Concomitantly, Korea's population growth rate declined. This paper extends that earlier work by examining patterns of consumption of these same commodities in the twenty most populous countries for the period 1970 through 1995. Developed countries, such as France, Germany, Japan, the United Kingdom, and the United States, show patterns of consumption that are stable (cement, copper, and salt) or grow slowly (aluminum). Some developing countries, including China, Thailand, and Turkey, show more rapid growth of consumption, especially of cement, copper, and aluminum. These changing patterns of mineral consumption in developing countries have important implications -- if they continue, there could be major increases in world mineral consumption and major increases in environmental residuals from mineral production and use. If China reaches the level of consumption of copper of developed countries, world consumption could reach levels more than twice that of 1995 (10.5 million tons).

Vegetarian dietary patterns have been reported to be associated with a number of favourable health outcomes in epidemiological studies, including the Adventist Health Study 2 (AHS-2). Such dietary patterns may vary and need further characterisation regarding foods consumed. The aims of the present study were to characterise and compare the food consumption patterns of several vegetarian and non-vegetarian diets. Dietary intake was measured using an FFQ among more than 89 000 members of the AHS-2 cohort. Vegetarian dietary patterns were defined a priori, based on the absence of certain animal foods in the diet. Foods were categorised into fifty-eight minor food groups comprising seventeen major food groups. The adjusted mean consumption of each food group for the vegetarian dietary patterns was compared with that for the non-vegetarian dietary pattern. Mean consumption was found to differ significantly across the dietary patterns for all food groups. Increased consumption of many plant foods including fruits, vegetables, avocados, non-fried potatoes, whole grains, legumes, soya foods, nuts and seeds was observed among vegetarians. Conversely, reduced consumption of meats, dairy products, eggs, refined grains, added fats, sweets, snack foods and non-water beverages was observed among vegetarians. Thus, although vegetarian dietary patterns in the AHS-2 have been defined based on the absence of animal foods in the diet, they differ greatly with respect to the consumption of many other food groups. These differences in food consumption patterns may be important in helping to explain the association of vegetarian diets with several important health outcomes.

Calorie intake and diet quality are influenced by the source of food and the place of consumption. This study examines the impacts of fast-food and full-service restaurant consumption on daily energy and nutrient intakes in US adults. Nationally representative data of 18,098 adults 18 years of age and above from the National Health and Nutrition Examination Survey 2003-2010 waves were analyzed. Outcomes included daily intake of total calories and 24 nutrients of public health concern. The key predictors were any food/beverage consumption in a day from fast-food or full-service restaurant, differentiated by consumption at home versus away from home. First-difference estimator addressed confounding bias from time-invariant unobservables such as personal food/beverage preferences by using within-individual variations in diet and restaurant consumption status between two nonconsecutive 24-h dietary recalls. Fast-food and full-service restaurant consumption, respectively, were associated with a net increase in daily total energy intake of 190.29 and 186.74 kcal, total fat of 10.61 and 9.58 g, saturated fat of 3.49 and 2.46 g, cholesterol of 10.34 and 57.90 mg, and sodium of 297.47 and 411.92 mg. The impact of fast-food and full-service restaurant consumption on energy and nutrient intakes differed by sex, race/ethnicity, education, income and weight status. Increased total energy, total fat, saturated fat, cholesterol and sodium intake were substantially larger when full-service restaurant food was consumed away from home than at home. A holistic policy intervention is warranted to target the American's overall dining-out behavior rather than fast-food consumption alone.

Consumption patterns and why people fish

Recreational and subsistence fishing play major roles in the lives of any people, although their importance in urban areas is often underestimated. There are fish and shellfish consumption advisories in the new York-New Jersey harbor estuary, particularly in the waters of the Newark Bay Complex. This paper examines fishing behavior, consumption patterns, and the reasons that people fish in the Newark Bay Complex. I test the null hypotheses that there are no differences among Asians, Blacks, Hispanics, and whites in consumption patterns for fish and crabs and in the reasons that they fish or crab. Most people either fished or crabbed, but not both. People who fish and crab ate more grams of crab than fish in a given meal; people who crab only consumed more grams of crab at a meal than those who fish only consumed of fish. Although 30% or more of the people who fished and crabbed in the Newark Bay Complex did not eat their self-caught fish or crabs 8-25% of the people ate more than 1500 g/month. Some people angling in the Newark Bay Complex are eating crabs at a rate well over 1500 g/month, and about 70% are eating crabs even though there is a total ban on both harvest and consumption because of the health risks from dioxin. Consumption patterns were negatively correlated with mean income and positively correlated with mean age. Most people rated relaxation and being outdoors the highest reasons or angling, although on an open-ended question they usually listed recreation. There were no ethnic differences in reasons for angling, although other studies have shown ethnic differences in consumption. Obtaining fish or crabs to eat, give away, trade, or sell were rated low, suggesting that consumption advisories fail partly because people are not primarily fishing or food

Inuvialuit in the Canadian Arctic have been experiencing a nutrition transition resulting in a decrease in nutrient-dense food consumption, which may, in part, explain this population's increasing chronic disease rates. Because the available literature is limited, the present study aimed to document the extent of this transition by examining current dietary patterns and socioeconomic factors affecting food group consumption. This cross-sectional study was conducted in three Inuvialuit communities in the Northwest Territories between 2007 and 2008. A validated food frequency questionnaire determined intake frequency of fruit and vegetables (FV), traditional foods (TF) and non-nutrient-dense foods (NNDF). Socioeconomic status (SES) was assessed by questions on education, ownership of items in working condition used to create a Material Style of Life (MSL) scale and residents in household employed/on income support. Daily intake frequencies were compared by gender and age group using Wilcoxon rank sum test. SES association with food group intake was determined using logistic regression. The response rate was 65-85%. One hundred and seventy-five participants were female and 55 were male, aged 19-84 years [mean (SD) 44 (14)]. Mean frequencies of FV and TF consumption were 1.6 (1.5) and 1.6 (1.7) times per day, respectively. NNDF were reported 9.2 (3.0) times per day. The highest MSL score (>12) was significantly associated with higher fruit (≥0.7 times per day) and higher TF intake (≥1.1 times per day) compared with the lowest score (≤7). An intermediate MSL score (8-12) was related to higher vegetable consumption (≥0.4 times per day). NNDF were consumed approximately seven times more frequently than TF in the present study, indicating that the dietary transition is well underway amongst Inuvialuit. Participants with higher SES were more likely to consume nutrient-dense foods, suggesting possible cost barriers. © 2010 The Authors. Journal compilation © 2010

Full Text Available The goal of this research was to assess patterns of beverage consumption and the contribution of total beverages and classes of beverages to overall energy intake and weight status. We conducted an analysis in a community-based study of 280 low-income overweight and obese African American women residing in the rural South. Participants provided baseline data including demographic characteristics, weight and two 24-h food and beverage dietary recalls. Mean energy intake from beverages was approximately 273 ± 192 kcal/day or 18.3% of total energy intake. The most commonly reported beverage was plain water, consumed by 88.2% of participants, followed closely by sweetened beverages (soft drinks, fruit drinks, sweetened teas, sweetened coffees and sweetened/flavored waters consumed by 78.9% of participants. In multiple regression analyses total energy and percent energy from beverages and specific categories of beverages were not significantly associated with current body mass index (BMI. It is widely accepted that negative energy balance may lead to future weight loss. Thus, reducing consumption of beverages that contribute energy but not important nutrients (e.g., sugar sweetened beverages could be an effective strategy for promoting future weight loss in this population.

Drinking plain water, such as tap or bottled water, provides hydration and satiety without adding calories. We examined plain water and sugar-sweetened beverage (SSB) consumption in relation to energy and nutrient intake at full-service restaurants. Data came from the 2005-2012 National Health and Nutrition Examination Survey, comprising a nationally-representative sample of 2900 adults who reported full-service restaurant consumption in 24-h dietary recalls. Linear regressions were performed to examine the differences in daily energy and nutrient intake at full-service restaurants by plain water and SSB consumption status, adjusting for individual characteristics and sampling design. Over 18% of U.S. adults had full-service restaurant consumption on any given day. Among full-service restaurant consumers, 16.7% consumed SSBs, 2.6% consumed plain water but no SSBs, and the remaining 80.7% consumed neither beverage at the restaurant. Compared to onsite SSB consumption, plain water but no SSB consumption was associated with reduced daily total energy intake at full-service restaurants by 443.4 kcal, added sugar intake by 58.2 g, saturated fat intake by 4.4 g, and sodium intake by 616.8 mg, respectively. Replacing SSBs with plain water consumption could be an effective strategy to balance energy/nutrient intake and prevent overconsumption at full-service restaurant setting.

This paper presents a theoretical framework for researching children and food consumption in the family. The proposed framework draws on contemporary social science approaches to the study of family decision making, food consumption patterns and routines, and consumer competence and food......-related lifestyle in order to understand children and families through their everyday practices. It suggest a new emphasis on children as active agents in the formation of family food consumption patterns and looks at children's food choices as embedded in everyday family life. We focus especially on the construct...... of the "Consumer Competence" of the child as one important aspect determining the way a child is involved in and gains influence over family food consumption. The paper also demonstrates how a mixed methods design, employing ethnographic and survey techniques, involves advances in methodological and analytical...

Microbial enhanced oil recovery (MEOR) depends on the in situ microbial activity to release trapped oil in reservoirs. In practice, undesired consumption is a universal phenomenon but cannot be observed effectively in small-scale physical simulations due to the scale effect. The present paper investigates the dynamics of oil recovery, biomass and nutrient consumption in a series of flooding experiments in a dedicated large-scale sand-pack column. First, control experiments of nutrient transportation with and without microbial consumption were conducted, which characterized the nutrient loss during transportation. Then, a standard microbial flooding experiment was performed recovering additional oil (4.9 % Original Oil in Place, OOIP), during which microbial activity mostly occurred upstream, where oil saturation declined earlier and steeper than downstream in the column. Subsequently, more oil remained downstream due to nutrient shortage. Finally, further research was conducted to enhance the ultimate recovery by optimizing the injection strategy. An extra 3.5 % OOIP was recovered when the nutrients were injected in the middle of the column, and another additional 11.9 % OOIP were recovered by altering the timing of nutrient injection.

Soya foods are one of the recommended alternatives to meat in many dietary guidelines. While this is expected to increase the intake of some nutrients, potential concerns regarding others have been raised. The purpose of the present study was to examine the prevalence and the association of soya food consumption with nutrient intakes and dietary patterns of Canadians (age ≥ 2 years). Cross-sectional data from the 2004 Canadian Community Health Survey (Cycle 2.2; n 33,218) were used to classify soya consumers and non-consumers. Soya consumers were further divided into two groups based on their soya protein intake. Sample weights were applied and logistic regression analysis was used to explore the association between nutrient intakes and soya consumption, with cultural background, sex, age and economic status being included as covariates. On any given day, 3.3% (n 1085) of Canadians consume soya foods, with females, Asian Canadians and adults with post-secondary education being more likely to be soya consumers. As a whole, adolescent and adult respondents who had consumed at least one soya food during their 24 h dietary recall had higher energy intakes, as well as increased intakes of nutrients such as protein, fibre, vitamin C, vitamin B6, naturally occurring folate, thiamin, Ca, P, Mg, PUFA, Fe and K and lowered intakes of saturated fat. These data indicate that soya food consumption is associated with improved diet quality of Canadians. However, future research is necessary to investigate the association between increased energy intake and soya consumption.

Mediterranean food consumption patterns: low environmental impacts and significant health-nutrition benefits.

The Mediterranean dietary patterns comply better with recommended nutrient and micronutrient intakes. The Mediterranean diet (MD) was associated with reduced mortality and lower risk for metabolic chronic diseases. It has also low ecological, carbon and water footprints due to its high share of plant-based foods. In fact, the share of plant-based dietary energy is higher in the Mediterranean than in Northern Europe. The Mediterranean hotspot is a major centre of plant and crop diversity. Mediterranean people gather and consume about 2300 plant species. This review paper aims at highlighting the nutrition-health benefits of the MD and analysing the main environmental impacts of the Mediterranean food consumption patterns. There is a growing body of scientific evidence that the MD has significant health-nutrition benefits and low environmental footprints, so there is urgent need to reverse the ongoing erosion of the MD heritage and to promote it as a sustainable diets model.

Foods, Nutrients, and Dietary Patterns: Interconnections and Implications for Dietary Guidelines12

Satija, Ambika; Hu, Frank B

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

Much of the current literature on diet-colorectal cancer (CRC) associations focused on studies of single foods/nutrients, whereas less is known about nutrient patterns. We investigated the association between major nutrient patterns and CRC risk in participants of the European Prospective Investigation into Cancer and Nutrition (EPIC) study. Among 477 312 participants, intakes of 23 nutrients were estimated from validated dietary questionnaires. Using results from a previous principal component (PC) analysis, four major nutrient patterns were identified. Hazard ratios (HRs) and 95% confidence intervals (CIs) were computed for the association of each of the four patterns and CRC incidence using multivariate Cox proportional hazards models with adjustment for established CRC risk factors. During an average of 11 years of follow-up, 4517 incident cases of CRC were documented. A nutrient pattern characterised by high intakes of vitamins and minerals was inversely associated with CRC (HR per 1 s.d.=0.94, 95% CI: 0.92-0.98) as was a pattern characterised by total protein, riboflavin, phosphorus and calcium (HR (1 s.d.)=0.96, 95% CI: 0.93-0.99). The remaining two patterns were not significantly associated with CRC risk. Analysing nutrient patterns may improve our understanding of how groups of nutrients relate to CRC.

Frequent consumption of energy-dense, nutrient-poor snack foods is an eating behavior of public health concern. This study was designed to inform strategies for reducing adolescent intake of energy-dense snack foods by identifying individual and environmental influences. Surveys were completed in 2009-2010 by 2540 adolescents (54% females, mean age = 14.5 ± 2.0, 80% nonwhite) in Minneapolis-St. Paul, Minnesota schools. Daily servings of energy-dense snack food was assessed using a food frequency questionnaire that asked about consumption of 21 common snack food items, such as potato chips, cookies, and candy. Data representing characteristics of adolescents' environments were collected from parents/caregivers, friends, school personnel, Geographic Information System sources, and a content analysis of favorite television shows. Linear regression was used to examine relationships between each individual or environmental characteristic and snack food consumption in separate models and also to examine relationships in a model including all of the characteristics simultaneously. The factors found to be significantly associated with higher energy-dense snack food intake represented individual attitudes/behaviors (e.g., snacking while watching television) and characteristics of home/family (e.g., home unhealthy food availability), peer (friends' energy-dense snack food consumption), and school (e.g., student snack consumption norms) environments. In total, 25.5% of the variance in adolescents' energy-dense snack food consumption was explained when factors from within each context were examined together. The results suggest that the design of interventions targeting improvement in the dietary quality of adolescents' snack food choices should address relevant individual factors (e.g., eating while watching television) along with characteristics of their home/family (e.g., limiting the availability of unhealthy foods), peer (e.g., guiding the efforts of a peer leader in

A longitudinal multivariate analysis was used to determine whether differences in energy and nutrient intakes were present for women classified into different eating patterns. Ten multidimensional eating patterns were created based on the proportion of energy consumed at home and at seven away-from-home locations. Data were from 1,120 women aged 19 through 50 years who were surveyed up to six times over a 1-year period as part of the 1985 Continuing Survey of Food Intake by Individuals, US Department of Agriculture. Data from 5,993 days were analyzed. To examine differences in energy and nutrient intakes, longitudinal multivariate analyses were used to control for eating pattern and factors such as demographics, season, and day of week. Younger women in the Fast Food eating pattern consumed the greatest intakes of energy, total fat, saturated fat, cholesterol, and sodium. Well-educated, higher-income women in the Restaurant pattern consumed diets with the highest overall fat density. Nutrient densities for dietary fiber, calcium, vitamin C, and folacin were particularly low in away-from-home eating patterns. In contrast, moderately educated, middle-aged and middle-income women in the Home Mixed eating pattern (70% at home, 30% away from home) consumed the most healthful diets. We conclude that knowledge of demographics such as income and education is not enough to target dietary interventions. Rather, educational efforts must consider both demographics and the location of away-from-home eating. This will allow development of behavioral change strategies that consider food choices dictated by the eating environment as well as personal knowledge and attitude factors related to adoption of healthful food choices.

The German National Nutrition Monitoring (NEMONIT) is a longitudinal and nationwide study to assess changes in food consumption and nutrient intake in Germany. A sample of 1840 participants (baseline age: 14-80 years) was drawn from the nationally representative German National Nutrition Survey (NVS) II (2005-2007). The participants have been interviewed by telephone annually since 2008. Food consumption was assessed by two 24-h recalls in the NVS II and the 4 years of NEMONIT (2008-2012/2013), respectively. Energy and nutrient intakes were calculated using the German Nutrient Database 3.02. Diet quality was evaluated using the Healthy Eating Index-NVS (HEI-NVS) II. Time trends were analysed by generalised estimating equation. Consumption of fruit/fruit products and fruit juice/nectar among men and women decreased, whereas consumption of water, soft drinks and coffee/tea increased over the 6-year period. Furthermore, increased consumption of confectionery and animal fats was observed among women. HEI-NVS II did not change since NVS II in both sexes. There were no changes in energy and protein intakes, but carbohydrate intake declined while fat intake increased over time. Regarding micronutrients, a decreasing intake of thiamin, riboflavin and vitamin B6 was observed in both sexes, but intake of Mg, Fe and niacin increased among women over time. In conclusion, food consumption and nutrient intake remained relatively stable between 2005-2007 and 2012/2013 within this German cohort. A few favourable and unfavourable changes were observed. Compared with national dietary guidelines, consumption of food of plant origin remained too low and consumption of meat/meat products remained too high in Germany.

The US Department of Agriculture (USDA) Food Patterns, released as part of the 2010 Dietary Guidelines for Americans, are designed to meet nutrient needs without exceeding energy requirements. They identify amounts to consume from each food group and recommend that nutrient-dense forms-lean or low-fat, without added sugars or salt-be consumed. Americans fall short of most food group intake targets and do not consume foods in nutrient-dense forms. Intake of calories from solid fats and added sugars exceed maximum limits by large margins. Our aim was to determine the potential effect on meeting USDA Food Pattern nutrient adequacy and moderation goals if Americans consumed the recommended quantities from each food group, but did not implement the advice to select nutrient-dense forms of food and instead made more typical food choices. Food-pattern modeling analysis using the USDA Food Patterns, which are structured to allow modifications in one or more aspects of the patterns, was used. Nutrient profiles for each food group were modified by replacing each nutrient-dense representative food with a similar but typical choice. Typical nutrient profiles were used to determine the energy and nutrient content of the food patterns. Moderation goals are not met when amounts of food in the USDA Food Patterns are followed and typical rather than nutrient-dense food choices are made. Energy, total fat, saturated fat, and sodium exceed limits in all patterns, often by substantial margins. With typical choices, calories were 15% to 30% (ie, 350 to 450 kcal) above the target calorie level for each pattern. Adequacy goals were not substantially affected by the use of typical food choices. If consumers consume the recommended quantities from each food group and subgroup, but fail to choose foods in low-fat, no-added-sugars, and low-sodium forms, they will not meet the USDA Food Patterns moderation goals or the 2010 Dietary Guidelines for Americans.

Full text: Nutrition is central in the prevention of food-related non-communicable diseases representing an important health risk factor and an enormous socio-economic burden for Mediterranean societies. Nevertheless, assessment of food systems and diets sustainability should take into account not only their health benefits but also their environmental impacts. This work aims at analysing the main environmental impacts of the Mediterranean food consumption patterns (MFCPs) and at highlighting their nutrition and health benefits. The paper provides a review on nutrition and health benefits of the traditional Mediterranean diet (MD) as well as on water and land resources and biodiversity in the Mediterranean. FAO food consumption statistics and standard footprint data were used to characterise the MFCP and to calculate and discuss environmental impacts, i.e. water, carbon and ecological footprints. The Mediterranean hotspot is a major centre of plant and crop diversity. Mediterranean people gather and consume about 2,300 plant species. The share of plant-based energy in the diet is higher in the Mediterranean than in Northern Europe and America. Peoples adhering to the Mediterranean dietary patterns comply better with recommended nutrient and micronutrients intakes. The MD was associated with reduced mortality and lower risk for obesity, type 2 diabetes, cardiovascular diseases and some cancers. During the last decades, the ecological footprint (EF) per capita in the Mediterranean increased while the biocapacity decreased thus the ecological deficit increased. The carbon footprint alone is generally higher than the biocapacity. MENA region has a lower EF than North America. Food consumption represents the highest share of water footprint of consumption (WFC) in the Mediterranean. WFC is lower in Mediterranean countries, especially MENA ones, than in North America. The traditional MD offers considerable health benefits and has lower environmental impacts than Northern

An effective consumer-oriented climate policy requires knowing the GHG reduction potential of sustainable consumption. The aim of this study is to draw lessons from differences in consumption between households with high and low GHG emissions. We evaluate a survey of 14,500 households and use a method that allows measuring changes in price level of consumption. Comparing the 10% of households with the highest GHG emissions per capita with the lowest 10% - controlling for differences in expenditure level and household structure - we find a range 5-17 tons of CO{sub 2}-equivalent per capita and year. The observed differences stem mainly from heating, electricity use, car use, and travel by aircraft. Consumption patterns with low GHG emissions are characterized by less spending on mobility, but more on leisure and quality oriented consumption (leading to higher prices per unit). Further characteristics are: a higher share of organic food, low meat consumption and fewer detached single family houses. Our findings imply that a significant reduction in GHG emissions would be possible by adopting real-world consumption patterns observable in society. The twin challenge is to shift consumption towards more climate friendly patterns, and to prevent any trend towards high emitting consumption patterns.

The status of energy consumption and air pollution in China is serious. It is important to analyze and predict the different fuel consumption of various types of vehicles under different influence factors. In order to fully describe the relationship between fuel consumption and the impact factors, massive amounts of floating vehicle data were used. The fuel consumption pattern and congestion pattern based on large samples of historical floating vehicle data were explored, drivers' information and vehicles' parameters from different group classification were probed, and the average velocity and average fuel consumption in the temporal dimension and spatial dimension were analyzed respectively. The fuel consumption forecasting model was established by using a Back Propagation Neural Network. Part of the sample set was used to train the forecasting model and the remaining part of the sample set was used as input to the forecasting model. Copyright © 2017. Published by Elsevier B.V.

In order to provide better advice for prevention of obesity and eating disorders among children, there is a need to have more knowledge of their dietary patterns. This study examined meal and snacking patterns of primary school children in Tehran. A total of 761 male and female primary school children from all educational areas in Tehran were recruited in a cross-sectional survey. The data was collected by interviewing the students and their mothers or caregivers. Information on food consumption patterns was collected by one 24-h-recall and one snack-oriented food frequency questionnaire which covered a period of 1 month. Means, standard deviations, frequencies, percentages, energy and nutrient analyzes and nutrient densities were reported. All of the students snacked at least once on the day of the survey. Snacks provided 38% of total energy intake by the students. Fruits and sweet snacks were consumed by almost all of the students during a week. Energy and most nutrient intakes from meals were greater than those consumed from snacks. Snacks had a higher density of fiber, carbohydrate, calcium, iron, vitamin C, riboflavin and thiamin and had a lower density of protein, fat and niacin, compared with main meals. Salty snacks such as extruded cheese curls (Cheetos) and chips were not consumed so often. Results provide detailed information about dietary patterns, which in turn enable development of targeted messages and/or interventions to improve nutritional status of school children.

The study is a case-control analysis of whether depression impairs physical and cognitive functioning and quality of life, and whether there is a relationship between nutrient deficiencies and these adverse changes. A total of 130 older subjects participated in the study: 65 with diagnosed depression (16 men and 49 women) and 65 age- and sex-matched controls without depression. All patients underwent comprehensive geriatric assessment. Nutritional state was assessed with the Mini Nutritional Assessment, cognitive performance was evaluated by the Mini-Mental State Examination and physical functioning by the Timed "Up & Go" test and handgrip strength. The pattern of consumption of various nutrients was analyzed in detail. The differences in cognitive functioning observed between the groups were related to specific nutrient intake, as was handgrip strength to some extent. The differences in nutritional status, several functional tests and muscle strength were related to both the presence of depression and inappropriate consumption of certain nutrients. The incidence of falls and poor quality of life may be partially associated with the presence of depression. The inappropriate intake of selected nutrients may impair the functioning and quality of life of older adults with depression, such as the excess consumption of sucrose and insufficient consumption of protein, fiber, eicosapentaenoic acid, niacin and vitamin B6. Particular nutrients should be translated into dietary patterns which allow the individual patient to address these nutrient deficiencies.

Design: Participants were children aged 2–18 years (n=13,339, from the National Health and Nutrition Examination Survey 2003–2010. Least square means of total energy and nutrient intake, and the percentage of the population below the estimated average requirement (EAR or above the adequate intake (AI among apple consumers and non-consumers were examined. Results: Consumers of total apple products had higher (p<0.01 total intakes of fiber, magnesium, and potassium and lower intakes of total fat, saturated fatty acids, monounsaturated fatty acid, and sodium than non-consumers. Apple consumers had higher (p<0.01 total sugar intake, but lower intake of added sugars compared to non-consumers. A lower (p<0.01 percentage of apple consumers were below the EAR for 13 of the 16 nutrients studied. Apple consumers had approximately a 10 percentage unit difference below the EAR for calcium and magnesium, and vitamins A, C, D, and E, than non-consumers. The percentage above the AI for fiber was significantly (p<0.0001 higher among total apple consumers (6.24±0.45 g compared to non-consumers (0.57±0.07 g. The results were similar for individual apple products (i.e. apple juice, applesauce, and whole apples. Conclusion: Consumption of any forms of apples provided valuable nutrients in the diets of children.

Most studies showing that children consuming breakfast have better nutrient intakes, diet quality, and lower weight than breakfast skippers have the incorrect premise that breakfast meals are homogeneous. The purpose of this study was to classify breakfast meals into patterns and determine the association of the breakfast patterns with daily and breakfast nutrient intakes, diet quality, and weight. Data from children (2-18 years of age; N = 14,200) participating in the National Health and Nutrition Examination Survey 2001-2008 were used. Intake was determined from one day 24-hour dietary recalls. Diet quality was measured using the Healthy Eating Index-2005 (HEI-2005). Body mass index (BMI) z-scores were determined. Twelve patterns (including No Breakfast [∼19% of population]), explaining 63% of the variance in energy from breakfast, were examined. Covariate adjusted general linear models were used to compare outcome variables of consumers of different patterns with breakfast skippers. The p value was Bonferroni corrected (eat Cereal (RTEC)/ LFM, RTEC/LFM, Cooked Cereal/Milk/FJ, and Whole Fruit patterns had higher total HEI-2005 scores than breakfast skippers; those consuming the MPF/ Grain/FJ pattern had lower diet quality than breakfast skippers. Consumption of the Grain/ LFM/Sweets/FJ, PSRTEC/whole milk, Soft Drinks/ FJ/Grain/Potatoes, RTEC/whole milk, and Cooked Cereal/ Milk/ FJ patterns was associated with lower BMI z-scores than seen in breakfast skippers. There are dietary and weight advantages of consuming breakfast, especially breakfasts that include grains, cereals, LFM, and fruit/ FJ, in contrast to the potential adverse effects of skipping breakfast.

The paper presents evidence on the impact of individual characteristics as well as regional macroeconomic factors on changes in fat, protein, alcohol and tobacco consumption, and on diet's diversity during the transition period 1994 - 2004 in Russia. The results from estimating first difference demand functions using Russian Longitudinal Monitoring Survey (RLMS) data suggest that individual characteristics such as initial consumption patterns, gender, education, household income, and access to a garden plot all have a significant impact on the consumption behaviour. Regarding the macroeconomic variables, inflation has a significant impact on alcohol and tobacco consumption, while unemployment significantly impacts only smoking behaviour. Russian consumers respond to own prices of fat and protein as well as to own prices of alcohol and tobacco but to a lesser extent. Analysis of subsamples based on different initial consumption patterns reveals significant heterogeneity in consumption responses.

Full Text Available During Ramadan fasting quantity and quality of dietary intake may change. There was no data on nutrient patterns in Ramadan fasting. The purpose of this study was to identify Ramadan major nutrient patterns among those who fast in Tehran, Iran. 510 fasting people aged 18-65 years and BMI 18.5-40 Kg/m2 were recruited in our study by 2-stage cluster sampling method in June-July 2014. Data on the socio-demographic and physical activity level were collected by questionnaire. Usual diet during Ramadan was estimated by valid and reliable food frequency questionnaire. BMI was calculated based on measured height and weight. Three nutrient patterns derived by conducting principal component factor analysis on 30 major nutrients. Micronutrient and fiber pattern which characterized by high intake of vitamin K, total fiber, iron, manganese, magnesium, β-carotene, folate, vitamin B12, potassium and calcium was adversely associated with weight (b=-0.16, P= 0.004. High protein pattern had great loadings on protein, riboflavin, phosphorous and zinc which physical activity level was decreased by tertiles of this pattern (b=0.13, P=0.02. High carbohydrate pattern which presented high positive loadings on carbohydrate and thiamin and negative loading on total fat, poly unsaturated fatty acids and monounsaturated fatty acids was positively associated with BMI (b= 0.12, P=0.03. Adherence to different Ramadan nutrient patterns is associated with weight, BMI and physical activity level. People on high in carbohydrate may have a higher BMI and low micronutrient density diet that should be considered in Ramadan fasting nutrition educational programs.

Full Text Available Economic growth in developing countries and globalization of the food sector is leading to increasingly similar food consumption patterns worldwide. The aim of this study was to describe similarities and differences in the contributions of main food groups to energy and nutrient intakes in five developed countries across three continents. We obtained summary reports of national food consumption survey data from Australia, France, Denmark, the Netherlands, and the United States. Survey years spanned 2003–2012; sample size ranged from 1444 to 17,386. To mitigate heterogeneity of food groups across countries, we recategorized each survey’s reported food groups and subgroups into eight main food groups and, for three countries, a ninth “mixed dishes” group. We determined the percent contribution of each food group to mean daily intakes of energy, saturated fat, sodium, fiber, and ten vitamins and minerals that are commonly under-consumed. Differences in findings from surveys utilizing a foods-as-consumed versus a disaggregated or ingredients approach to food group composition and contributions from the milk and milk products group, a source of several under-consumed nutrients, were explored. Patterns of food group contributions to energy and nutrient intakes were generally similar across countries. Some differences were attributable to the analytical approach used by the surveys. For the meat/protein, milk and milk products, vegetables, and fruit groups, percent contributions to key nutrient intakes exceeded percent contributions to energy intake. The mixed dishes group provided 10%–20% of total daily energy and a similar 10%–25% of the daily intake of several nutrients. This descriptive study contributes to an understanding of food group consumption patterns in developed countries.

Land use has obvious influence on surface water quality; thus, it is important to understand the effects of land use patterns on surface water quality. This study explored the relationships between land use patterns and stream nutrient levels, including ammonium-N (NH4 (+)-N), nitrate-N (NO3 (-)-N), total N (TN), dissolved P (DP), and total P (TP) concentrations, in one forest and 12 agricultural catchments in subtropical central China. The results indicated that the TN concentrations ranged between 0.90 and 6.50 mg L(-1) and the TP concentrations ranged between 0.08 and 0.53 mg L(-1), showing that moderate nutrient pollution occurred in the catchments. The proportional areal coverages of forests, paddy fields, tea fields, residential areas, and water had distinct effects on stream nutrient levels. Except for the forest, all studied land use types had a potential to increase stream nutrient levels in the catchments. The land use pattern indices at the landscape level were significantly correlated to N nutrients but rarely correlated to P nutrients in stream water, whereas the influence of the land use pattern indices at the class level on stream water quality differentiated among the land use types and nutrient species. Multiple regression analysis suggested that land use pattern indices at the class level, including patch density (PD), largest patch index (LPI), mean shape index (SHMN), and mean Euclidian nearest neighbor distance (ENNMN), played an intrinsic role in influencing stream nutrient quality, and these four indices explained 35.08 % of the variability of stream nutrient levels in the catchments (pstream nutrient pollution in subtropical central China.

The aim of this paper is to analyse the relationship between household consumption patterns and pollution in the Spanish economy. The analysis was carried using a Social Accounting Matrix (SAM) for the Spanish economy prepared for 1999. Taking the final demand of households as the exogenous account in the SAM framework and combining this with the information provided by the Household Budget Continuous Survey on income and consumption (INE, 1999), we analyse the pollution produced by both the economy and households in order to satisfy consumption requirements. We also consider the effects of income inequality on expenditure levels, establishing a link between income level, consumption patterns, propensity to consume and CO 2 emissions. (author)

Gavelle, Erwan de; Huneau, Jean-François; Mariotti, François

Protein food intake appears to partially structure dietary patterns, as most current emergent diets (e.g., vegetarian and flexitarian) can be described according to their levels of specific protein sources. However, few data are available on dietary protein patterns in the general population and their association with nutrient adequacy. Based on protein food intake data concerning 1678 adults from a representative French national dietary survey, and non-negative-matrix factorization followed by cluster analysis, we were able to identify distinctive dietary protein patterns and compare their nutrient adequacy (using PANDiet probabilistic scoring). The findings revealed eight patterns that clearly discriminate protein intakes and were characterized by the intakes of one or more specific protein foods: 'Processed meat', 'Poultry', 'Pork', 'Traditional', 'Milk', 'Take-away', 'Beef' and 'Fish'. 'Fish eaters' and 'Milk drinkers' had the highest overall nutrient adequacy, whereas that of 'Pork' and 'Take-away eaters' was the lowest. Nutrient adequacy could often be accounted for by the characteristics of the food contributing to protein intake: 'Meat eaters' had high probability of adequacy for iron and zinc, for example. We concluded that protein patterns constitute strong elements in the background structure of the dietary intake and are associated with the nutrient profile that they convey.

The effect of different breakfast consumption patterns on nutrient intake, diet quality, and weight/adiposity status is unknown. To compare nutrient intake, diet quality, and weight/adiposity measures of consumers assigned to different breakfast patterns with breakfast skippers. These associations were assessed in adults 19+ years (N=18,988) participating in the 2001-2008 National Health and Nutrition Examination Survey. Intake was determined from 1-day 24-hour dietary recall. Diet quality was quantified using the Healthy Eating Index-2005. Body mass index (calculated as kg/m(2)) and waist circumferences were determined. Twelve patterns (including No Breakfast [approximately 19% of population]), explaining 58% of the variance in energy from the breakfast meal, were examined. Covariate adjusted general linear models were used to compare nutrient intakes, Healthy Eating Index-2005 scores, and body mass index/waist circumference of consumers of different patterns with breakfast skippers. The P value was Bonferroni corrected (Juice and Presweetened Ready-to-Eat Cereal (RTEC)/Lower-Fat Milk patterns had lower daily intakes of nutrients to limit (added sugars, saturated fatty acids, solid fats, cholesterol, and sodium) than breakfast skippers. Consumers of the Grain/100% Fruit Juice; Presweetened RTEC/Lower-Fat Milk; and RTEC/Lower-Fat Milk/Whole Fruit/100% Fruit Juice patterns had higher daily intakes of all shortfall nutrients examined (dietary fiber; vitamins A, D, and C; calcium, potassium, folate, iron, and magnesium) than breakfast skippers. Consumers of the Grain/100% Fruit Juice; Grain; Presweetened RTEC/Lower-Fat Milk; RTEC/Lower-Fat Milk/Whole Fruit/100% Fruit Juice; Cooked Cereal; Lower-Fat Milk/Whole Fruit; and Whole Fruit patterns had higher Healthy Eating Index-2005 scores than breakfast skippers.

Background: Diverse perspectives have influenced fish consumption choices. Objectives: We summarized the issue of fish consumption choice from toxicological, nutritional, ecological, and economic points of view; identified areas of overlap and disagreement among these viewpoints; and reviewed effects of previous fish consumption advisories. Methods: We reviewed published scientific literature, public health guidelines, and advisories related to fish consumption, focusing on advisories targeted at U.S. populations. However, our conclusions apply to groups having similar fish consumption patterns. Discussion: There are many possible combinations of matters related to fish consumption, but few, if any, fish consumption patterns optimize all domains. Fish provides a rich source of protein and other nutrients, but because of contamination by methylmercury and other toxicants, higher fish intake often leads to greater toxicant exposure. Furthermore, stocks of wild fish are not adequate to meet the nutrient demands of the growing world population, and fish consumption choices also have a broad economic impact on the fishing industry. Most guidance does not account for ecological and economic impacts of different fish consumption choices. Conclusion: Despite the relative lack of information integrating the health, ecological, and economic impacts of different fish choices, clear and simple guidance is necessary to effect desired changes. Thus, more comprehensive advice can be developed to describe the multiple impacts of fish consumption. In addition, policy and fishery management inter-ventions will be necessary to ensure long-term availability of fish as an important source of human nutrition. PMID:22534056

To examine whether yogurt consumption is associated with a healthier dietary pattern and with a better cardio-metabolic risk profile among healthy individuals classified on the basis of their body mass index (BMI). A 91-item food frequency questionnaire, including data on yogurt consumption, was administered to 664 subjects from the INFOGENE study. After principal component analysis, two factors were retained, thus classified as the Prudent and Western dietary patterns. Yogurt was a significant contributor to the Prudent dietary pattern. Moreover, yogurt consumption was associated with lower body weight, waist-to-hip ratio, and waist circumference and tended to be associated with a lower BMI. Consumers had lower levels of fasting total cholesterol and insulin. Consumers of yogurt had a positive Prudent dietary pattern mean score, while the opposite trend was observed in non-consumers of yogurt. Overweight/obese individuals who were consumers of yogurts exhibited a more favorable cardio-metabolic profile characterized by lower plasma triglyceride and insulin levels than non-consumers within the same range of BMI. There was no difference in total yogurt consumption between normal-weight individuals and overweight/obese individuals. However, normal-weight subjects had more daily servings of high-fat yogurt and less daily servings of fat-free yogurt compared to overweight/obese individuals. Being a significant contributor to the Prudent dietary pattern, yogurt consumption may be associated with healthy eating. Also, yogurt consumption may be associated with lower anthropometric indicators and a more beneficial cardio-metabolic risk profile in overweight/obese individuals.

Full Text Available Non-intrusive load monitoring (NILM, monitoring single-appliance consumption level by decomposing the aggregated energy consumption, is a novel and economic technology that is beneficial to energy utilities and energy demand management strategies development. Hardware costs of high-frequency sampling and algorithm’s computational complexity hampered NILM large-scale application. However, low sampling data shows poor performance in event detection when multiple appliances are simultaneously turned on. In this paper, we contribute an iterative disaggregation approach that is based on appliance consumption pattern (ILDACP. Our approach combined Fuzzy C-means clustering algorithm, which provide an initial appliance operating status, and sub-sequence searching Dynamic Time Warping, which retrieves single energy consumption based on the typical power consumption pattern. Results show that the proposed approach is effective to accurately disaggregate power consumption, and is suitable for the situation where different appliances are simultaneously operated. Also, the approach has lower computational complexity than Hidden Markov Model method and it is easy to implement in the household without installing special equipment.

Little is known about the consumption of organic food during pregnancy. The aim of this study was to describe dietary characteristics associated with frequent consumption of organic food among pregnant women participating in the Norwegian Mother and Child Cohort Study (MoBa). The present study includes 63 808 women who during the years 2002-2007 answered two questionnaires, a general health questionnaire at gestational weeks 15 and a food frequency questionnaire at weeks 17-22. The exploration of food patterns by Principal component analyses (PCA) was followed by ANOVA analyses investigating how these food patterns as well as intake of selected food groups were associated with consumption of organic food. The first principal component (PC1) identified by PCA, accounting for 12% of the variation, was interpreted as a 'health and sustainability component', with high positive loadings for vegetables, fruit and berries, cooking oil, whole grain bread and cereal products and negative loadings for meat, including processed meat, white bread, and cakes and sweets. Frequent consumption of organic food, which was reported among 9.1% of participants (n = 5786), was associated with increased scores on the 'health and sustainability component' (p organic food had a diet with higher density of fiber and most nutrients such as folate, beta-carotene and vitamin C, and lower density of sodium compared to participants with no or low organic consumption. The present study showed that pregnant Norwegian women reporting frequent consumption of organically produced food had dietary pattern and quality more in line with public advice for healthy and sustainable diets. A methodological implication is that the overall diet needs to be included in future studies of potential health outcomes related to consumption of organic food during pregnancy.

Aggregated national or regional level electricity consumption data fail to capture the spatial variation in consumption, a function of location, climate, topography, and local economics. Spatial monitoring of electricity usage patterns helps to understand derivers of location specific consumption behavior and develop models to cater to the consumer needs, plan efficiency measures, identify settled areas lacking access, and allows for future planning through assessing requirements. Developed countries have started to deploy sensor systems such as smart meters to gather information on local level consumption patterns, but such infrastructure is virtually nonexistent in developing nations, resulting in serious dearth of reliable data for planners and policy makers. Remote sensing of artificial nighttime lights from human settlements have proven useful to study electricity consumptions from global to regional scales, however, local level studies remain scarce. Using the differences in spatial characteristics among different urban neighborhoods such as industrial, commercial and residential, observable through very high resolution day time satellite images (lights observations, which we use as a proxy for electricity consumption in the absence of ground level consumption data. The overall trends observed through this analysis provides useful explanations helping in understanding of broad electricity consumption patterns in urban areas lacking ground level observations. This study thus highlights possible application of remote sensing data driven methods in providing novel insights into local level socio-economic patterns that were hitherto undetected due to lack of ground data.

In this paper we aim to provide information about the transmission mechanism at work between investment and unemployment by looking at the consumption-saving pattern as a determinant of investment behaviour. Our starting hypothesis is that permanent shifts in the consumption-saving pattern will have permanent effects on investment, with subsequent consequences for the unemployment rate. To test this hypothesis we build an SVAR model for the Spanish economy seeking information about the respon...

Full Text Available Alcohol is the most used psychoactive substance among adolescents, is an important public health problem and a major risk factor for the health of this group. This study is regarding to the pattern of alcohol consumption by adolescents. Descriptive, correlational and cross-sectional study, with a sample of 378 adolescents, which are attending three high schools, in north-eastern Portugal. In the data collection we used a questionnaire. Data was analysed using SPSS. The prevalence of alcohol is 86.8%. The mean score of Alcohol Use Disorders Identification Test (AUDIT was 3.53±4.525 points. The vast majority of participants were located in the non-excessive alcohol consumption area (91.3%. The pattern of alcohol consumption differs significantly between gender (Wald: p ≤ 0,004 and the religious practice (Wald: p ≤ 0,027, with greater percentage of boys and students who did not practice any religion in excessive consumers. The prevalence of alcohol consumers is high. The proportion of young people with excessive consumption in our sample is lower than in other studies, but shows that there is a group of adolescents in excessive consumption. It found a relationship between consumption pattern, gender and religious practice. These results justify the development of public health interventions.

Nutrient balancing is well known in herbivores and omnivores, but has only recently been demonstrated in predators. To test how a predator might regulate nutrients when the prey varies in nutrient composition, we restricted juvenile Pardosa prativaga wolf spiders to diets of one of six fruit fly......, Drosophila melanogaster, prey types varying in lipid:protein composition during their second instar. We collected all fly remnants to estimate food and nutrient intake over each meal. The spiders adjusted their capture rate and nutrient extraction in response to prey mass and nutrient composition...... irrespective of energy intake. Intake was initially regulated to a constant lipid plus protein mass, but later spiders fed on prey with high proportions of protein increased consumption relative to spiders fed on other prey types. This pattern indicates that the spiders were prepared to overconsume vast...

During leaf senescence, nutrient rich compounds are transported to other parts of the plant and this 'resorption' recycles nutrients for future growth, reducing losses of potentially limiting nutrients. Variations in leaf chemistry resulting from nutrient resorption also directly affect litter quality, in turn, regulating decomposition rates and soil nutrient availability. Here we investigated stoichiometric patterns of nitrogen (N) and phosphorus (P) resorption efficiency at multiple spatial scales. First, we assembled a global database to explore nutrient resorption among and within biomes and to examine potential relationships between resorption stoichiometry and ecosystem nutrient status. Next, we used a forest regeneration chronosequence in Brazil to assess how resorption stoichiometry linked with a suite of other nutrient cycling measures and with ideas of how nutrient limitation may change over secondary forest regrowth. Finally, we measured N:P resorption ratios of six canopy tree species in a Costa Rican tropical forest. We calculated species-specific resorption ratios and compared them with patterns in leaf litter and topsoil nutrient concentrations. At the global scale, N:P resorption ratios increased with latitude and decreased with mean annual temperature (MAT) and precipitation (MAP; P1 in latitudes >23°. Focusing on tropical sites in our global dataset we found that, despite fewer data and a restricted latitudinal range, a significant relationship between latitude and N:P resorption ratios persisted (PAmazon Basin chronosequence of regenerating forests, where previous work reported a transition from apparent N limitation in younger forests to P limitation in mature forests, we found N resorption was highest in the youngest forest, whereas P resorption was greatest in the mature forest. Over the course of succession, N resorption efficiency leveled off but P resorption continued to increase with forest age. In Costa Rica, though we found species

Full Text Available Consumption is one of the basic indicators of human’s life. The level of human satisfaction is always influenced by the level of economic and social change in the culture of a region. According to Kotler, religion is part of a culture that can shape people's behavior. The purpose of this study is to analyze the influence of contextual factors and religiosity on food consumption patterns in Bandar Lampung, as well as to investigate the religiosity variables as an intervening variable on the contextual factors on food consumption patterns in Bandar Lampung. The results of the analysis showed that the relative and contextual factors cannot influence the consumers' buying behavior directly but influence the religiosity (as an intervening variable and the pattern of consumption indirectly.

Full Text Available Marijuana is one of the most consumed psychoactive in Colombia and worldwide. It has been observed that it has effects over central nervous system; in consequence it may affect the metabolism and nutritional status of marijuana users. This article intends to evaluate if consumption of marijuana and the activation of the cannabinoid system have the capacity to activate physiological mechanisms through which the intake and the nutrient metabolism get affected. As a result, it is found that the consumption of marijuana influences increasing the orexigenic stimulus and decreasing the anorexigenic stimulus, which influence increasing the ingestion and changing the production of important enzymes in the metabolism of fat. Likewise, it affects the appearance of alterations in the nutritional status of the consumers that involve the decrease of their body max index (BMI, which contrasts with the results related to the intake, thus highlights the importance of carry out deep studies that could explain this questioning.

Pizza consumption is a top contributor to children's and adolescents' caloric intake. The objective of this study was to examine children's and adolescents' pizza consumption patterns and its impact on their energy and nutrient intake. Twenty-four-hour dietary recall data for children aged 2 to 11 and adolescents aged 12 to 19 were drawn from the 2003-2004, 2005-2006, 2007-2008, and 2009-2010 National Health and Nutrition Examination Survey. We tested changes in consumption patterns, including by race/ethnicity, income, meal occasion, and source. Individual-level fixed effects regression models estimated the impact of pizza consumption on total energy intake (TEI) and intakes of sugar, saturated fat, and sodium. From 2003-2004 to 2009-2010, overall energy intake from pizza declined 25% among children (110 to 83 kcal, P ≤ .05). Among adolescents, although caloric intake from pizza among those who consumed pizza fell (801 to 624 kcal, P ≤ .05), overall pizza intake remained unchanged due to slightly higher pizza consumption prevalence. For children and adolescents, pizza intake fell (P ≤ .05) at dinner time and from fast food. For children and adolescents, respectively, pizza consumption was significantly associated with higher net daily TEI (84 kcal and 230 kcal) and higher intakes of saturated fat (3 g and 5 g) and sodium (134 mg and 484 mg) but not sugar intake, and such affects generally did not differ by sociodemographic characteristics. Pizza consumption as a snack or from fast-food restaurants had the greatest adverse impact on TEI. The adverse dietary effects of pizza consumption found in this study suggest that its consumption should be curbed and its nutrient content improved.

A feeding trial was conducted to determine the optimum level of crude protein (CP) in the diet of captive blackbuck (Antelope cervicapra) in which feed consumption and nutrient utilization are maximal. Fifteen blackbucks (BW 25-34 kg) were distributed into three groups of five each in an experiment of 75-days duration including a digestion trial of 5-day collection period. All the animals were offered 200 g of concentrates and fresh maize fodder ad libitum. The overall CP content of the three respective diets was 6.9%, 10.4% and 12.7%. Blood samples were collected on the last day of the experiment. Intake and digestibility of CP increased (p consumption and nutrient intake were not significantly different among the groups. However, digestibilities of most of the nutrients were higher in the 10.4% CP diet than in the 6.9% CP diet. The endogenous loss of nitrogen was similar among the groups. Based on the endogenous losses, minimum N requirement was calculated to be 776 mg/kg BW(0.75) /day, and to meet this requirement, diet must contain at least 8.27% CP. Serum urea nitrogen concentration increased (p consumption and serum metabolite profile of blackbucks. © 2011 Blackwell Verlag GmbH.

Full Text Available Background: Understanding different patterns of fish consumption is an important component for risk assessment of contaminants in fish. A few studies on food consumption had been conducted in Malaysia, but none of them focused specifically on fish consumption. The objectives of this study were to document the meal pattern among three major ethnics in Malaysia with respect to fish/seafood consumption, identify most frequently consumed fish and cooking method, and examine the influence of demographic factors on pattern of fish consumption among study subjects. Methods: A cross-sectional survey was conducted between February 2008 and May 2009 to investigate patterns of fish consumption among Malaysian adults in Peninsular Malaysia. Adults aged 18 years and above were randomly selected and fish consumption data were collected using a 3-day prospective food diary. Results: A total of 2,675 subjects, comprising male (44.2% and female (55.7% participants from major ethnics (Malays, 76.9%; Chinese, 14.7%; Indians, 8.3% with a mean age of 43.4±16.2 years, were involved in this study. The results revealed 10 most frequently consumed marine fish in descending order: Indian mackerel, anchovy, yellowtail and yellow-stripe scads, tuna, sardines, torpedo scad, Indian and short-fin scads, pomfret, red snapper, and king mackerel. Prawn and squid were also among the most preferred seafood by study subjects. The most frequently consumed freshwater fish were freshwater catfish and snakehead. The most preferred cooking style by Malaysians was deep-fried fish, followed by fish cooked in thick and/or thin chili gravy, fish curry, and fish cooked with coconut milk mixed with other spices and flavorings.

Full Text Available Trophic relationships are conditioned by population dynamics of interacting species in the community (species present, food web connections among them, and the strength of interactions, and on the consequences of these species interactions depend various ecosystem processes such as productivity and nutrient flux. Odontocetes target a wide range of prey items and are adapted to feeding at different depths. The aim of this report is to describe the patterns of prey consumption by small odontocetes, incorporating natural predatory patterns into a potential management scheme of strategic food sources, for both human and marine predators. Using the geo-statistical analysis tool of ArcGIS 9.2, maps illustrating the intensity and location of prey consumption were made for species with a sighting index (SPUE > 0.15. The biomass consumption emphasized the differences in habitat use by species. The trends in distribution of prey biomass removal by odontocetes particularly suggest a stratification of prey consumption primarily in shelf waters, with a prey biomass that is comprised basically by demersal fish and small pelagics (including Sardinella aurita, and into transition-oceanic depths where most of the predatory pattern would potentially rely on pelagic - mesopelagic squid and myctophids. Overall the spatial tendencies in regionalization presented in this contribution will serve as a base-line to assess ecosystem health and evaluate management scenarios.   Las relaciones tróficas son reguladas por la dinámica poblacional de las especies que interactúan dentro de la comunidad (especies presentes, conexiones interespecíficas, y nivel de interacción y de las consecuencias de esas interacciones para procesos del ecosistema como la productividad y el flujo de nutrientes.

Canopy and leaf composition drive patterns of nutrient release from pruning residues in a coffee agroforest.

Science.gov (United States)

Tully, Katherine L; Lawrence, Deborah

2012-06-01

In a coffee agroforest, the crop is cultivated under the shade of fruit-bearing and nitrogen (N)-fixing trees. These trees are periodically pruned to promote flowering and fruiting as well as to make nutrients stored in tree biomass available to plants. We investigated the effect of canopy composition and substrate quality on decomposition rates and patterns of nutrient release from pruning residues in a coffee agroforest located in Costa Rica's Central Valley. Initial phosphorus (P) release was enhanced under a canopy composed solely of N-fixing, Erythrina poeppigiana compared to a mixed canopy of Erythrina and Musa acuminata (banana). Both initial and final N release were similar under the two canopy types. However, after five months of decomposition, a higher proportion of initial N had been released under the single canopy. Although patterns of decomposition and nutrient release were not predicted by initial substrate quality, mass loss in leaf mixtures rates were well predicted by mean mass loss of their component species. This study identifies specific pruning regimes that may regulate N and P release during crucial growth periods, and it suggests that strategic pruning can enhance nutrient availability. For example, during the onset of rapid fruit growth, a two-species mixture may release more P than a three-species mixture. However, by the time of the harvest, the two- and three-species mixtures have released roughly the same amount of N and P. These nutrients do not always follow the same pattern, as N release can be maximized in single-species substrates, while P release is often facilitated in species mixtures. Our study indicates the importance of management practices in mediating patterns of nutrient release. Future research should investigate how canopy composition and farm management can also mediate on-farm nutrient losses.

The affinity for substance use among patrons of nightclubs has been well established. With novel psychoactive substances (NPS) quickly emerging on the European drug market, trends, and patterns of use are potentially changing. (1) The detection of subgroups of consumers in the electronic dance music scene of a major German metropolitan city, (2) describing the consumption patterns of these subgroups, (3) exploring the prevalence and type of NPS consumption in this population at nightlife events in Munich. A total of 1571 patrons answered questions regarding their own substance use and the emergence of NPS as well as their experience with these substances. A latent class analysis was employed to detect consumption patterns within the sample. A four class model was determined reflecting different consumption patterns: the conservative class (34.9%) whose substance was limited to cannabis; the traditional class (36.6%) which especially consumed traditional club drugs; the psychedelic class (17.5%) which, in addition to traditional club drugs also consumed psychedelic drugs; and an unselective class (10.9%) which displayed the greatest likelihood of consumption of all assessed drugs. "Smoking mixtures" and methylone were the new substances mentioned most often, the number of substances mentioned differed between latent classes. Specific strategies are needed to reduce harm in those displaying the riskiest substance use. Although NPS use is still a fringe phenomenon its prevalence is greater in this subpopulation than in the general population, especially among users in the high-risk unselective class.

Full Text Available Objectives. To describe traditional food (TF consumption and to evaluate its impact on nutrient intakes of preschool Inuit children from Nunavik. Design. A cross-sectional study. Methods. Dietary intakes of children were assessed with a single 24-hour recall (n=217. TF consumption at home and at the childcare centres was compared. Differences in children's nutrient intakes when consuming or not consuming at least 1 TF item were examined using ANCOVA. Results. A total of 245 children attending childcare centres in 10 communities of Nunavik were recruited between 2006 and 2010. The children's mean age was 25.0±9.6 months (11–54 months. Thirty-six percent of children had consumed at least 1 TF item on the day of the recall. TF contributed to 2.6% of total energy intake. Caribou and Arctic char were the most reported TF species. Land animals and fish/shellfish were the main contributors to energy intake from TF (38 and 33%, respectively. In spite of a low TF intake, children who consumed TF had significantly (p<0.05 higher intakes of protein, omega-3 fatty acids, iron, phosphorus, zinc, copper, selenium, niacin, pantothenic acid, riboflavin, and vitamin B12, and lower intakes of energy and carbohydrate compared with non-consumers. There was no significant difference in any of the socio-economic variables between children who consumed TF and those who did not. Conclusion. Although TF was not eaten much, it contributed significantly to the nutrient intakes of children. Consumption of TF should be encouraged as it provides many nutritional, economic, and sociocultural benefits.

Nutrient density: addressing the challenge of obesity.

Science.gov (United States)

Drewnowski, Adam

2017-10-30

Obesity rates are increasing worldwide. Potential reasons include excessive consumption of sugary beverages and energy-dense foods instead of more nutrient-rich options. On a per kJ basis, energy-dense grains, added sugars and fats cost less, whereas lean meats, seafood, leafy greens and whole fruit generally cost more. Given that consumer food choices are often driven by price, the observed social inequities in diet quality and health can be explained, in part, by nutrition economics. Achieving a nutrient-rich diet at an affordable cost has become progressively more difficult within the constraints of global food supply. However, given the necessary metrics and educational tools, it may be possible to eat better for less. New metrics of nutrient density help consumers identify foods, processed and unprocessed, that are nutrient-rich, affordable and appealing. Affordability metrics, created by adding food prices to food composition data, permit calculations of both kJ and nutrients per penny, allowing for new studies on the economic drivers of food choice. Merging dietary intake data with local or national food prices permits the estimation of individual-level diet costs. New metrics of nutrient balance can help identify those food patterns that provide optimal nutritional value. Behavioural factors, including cooking at home, have been associated with nutrition resilience, defined as healthier diets at lower cost. Studies of the energy and nutrient costs of the global food supply and diverse food patterns will permit a better understanding of the socioeconomic determinants of health. Dietary advice ought to be accompanied by economic feasibility studies.

The aim of our research was to describe cultural, socioeconomic and nutritional determinants associated with functional food consumption. Cross-sectional design in 5000 military men. Using mailed questionnaires, the functional food consumption frequency was recorded. Margarines fortified with phytosterols or phytostanols were used on a daily basis by 26.3% of the responders. Only 4.7% took a daily portion of probiotics, whereas 14.0% consumed one or more portions of nuts a week. One man out of three consumed one cup of tea daily, whereas 10.2% consumed one glass of red wine daily. Three or more portions of fruit a day were consumed by 19.1%, and two or more portions of vegetables a day by 26.6%. Only 12.3% consumed a portion of fatty fish weekly. After adjustment for age, body mass index, physical activity, use of vitamin supplements, smoking, marital status, cultural background, educational and income level, the daily consumption of fortified margarines increased with age. The consumption of fermented dairy products increased with physical activity and with the use of vitamin supplements. The consumption of fortified margarines, nuts, tea and fatty fish was strongly influenced by cultural background, with higher consumptions for Flemish-speaking men compared with French-speaking persons. Daily consumption of red wine was higher in French-speaking men and in higher educated men. Finally, functional food consumption was associated with a healthy dietary pattern. Age, physical activity, level of education, use of vitamin supplements and cultural background are predictors of functional food consumption patterns.

To describe the food consumption patterns of US children aged 2 and 3 years. Descriptive analysis of data collected in the Feeding Infants and Toddlers Study 2008 based on a single 24-hour dietary recall collected by telephone. A national random sample of children aged 2 and 3 years (n=1,461). The percentage of children consuming foods from specific food groups was estimated for the full sample of children aged 2 and 3 years and separately by year of age. About a third of 2-year-olds and a quarter of 3-year-olds consumed whole milk at least once in a day. About 70% of 2- and 3-year-olds consumed vegetables as a distinct food item at least once in day. French fries and other fried potatoes were the most commonly consumed vegetable. Almost three quarters of children (73%) consumed fruit as a distinct food item at least once in a day, and 59% consumed 100% juice. Fresh fruit was the most commonly consumed type of fruit. About 85% of children consumed some type of sweetened beverage, dessert, sweet, or salty snack in a day. Percentages of children consuming such foods were consistently higher for 3-year-olds than for 2-year-olds. Parents and caregivers should be encouraged to expose young children to a wide variety of fruits and vegetables, whole grains, low-fat dairy products, and healthier fats, and to limit consumption of low-nutrient, energy-dense foods and beverages. Dietary guidance should stress the fact that children in this age group have high nutrient needs and relatively low energy requirements, leaving little room for such foods. Parents need advice that is specific, practical, and actionable. Copyright © 2010 American Dietetic Association. Published by Elsevier Inc. All rights reserved.

Beverage-consumption patterns and associations with metabolic risk factors among low-income Latinos with uncontrolled type 2 diabetes.

Wang, Monica L; Lemon, Stephenie C; Olendzki, Barbara; Rosal, Milagros C

2013-12-01

In the United States, Latinos experience disproportionately higher rates of type 2 diabetes and diabetes-related complications than non-Latino whites. Sugar-sweetened beverage (SSB) consumption is strongly associated with increased risk of developing type 2 diabetes. Reducing caloric intake, particularly from energy-dense, low-nutrient foods or beverages, can be an effective and key strategy for metabolic and weight control. However, little is known about the contribution of various types of beverages, including but not limited to SSBs, to total caloric intake among Latinos with type 2 diabetes. Low-income Latinos (87.7% Puerto Rican) participating in a diabetes self-management intervention trial (N=238) provided cross-sectional, descriptive data on beverage-consumption patterns, anthropometric outcomes, and metabolic characteristics. Beverages accounted for one fifth of the total daily caloric intake. SSBs and milk beverages, respectively, contributed 9.6% of calories to overall daily caloric intake. Interventions directed at diabetes risk factors among low-income Latinos with diabetes can benefit from consideration of beverage-consumption behaviors as an important strategy to reduce caloric and sugar intake.

All patients underwent comprehensive geriatric assessment. Nutritional state was assessed with the Mini Nutritional Assessment, cognitive performance was evaluated by the Mini-Mental State Examination and physical functioning by the Timed “Up & Go” test and handgrip strength. The pattern of consumption of various nutrients was analyzed in detail.Results: The differences in cognitive functioning observed between the groups were related to specific nutrient intake, as was handgrip strength to some extent. The differences in nutritional status, several functional tests and muscle strength were related to both the presence of depression and inappropriate consumption of certain nutrients.Conclusion: The incidence of falls and poor quality of life may be partially associated with the presence of depression. The inappropriate intake of selected nutrients may impair the functioning and quality of life of older adults with depression, such as the excess consumption of sucrose and insufficient consumption of protein, fiber, eicosapentaenoic acid, niacin and vitamin B6. Particular nutrients should be translated into dietary patterns which allow the individual patient to address these nutrient deficiencies. Keywords: aging, cognitive

Oesophageal epithelial cell proliferation and food consumption patterns following irradiation

International Nuclear Information System (INIS)

Burholt, D.R.

1986-01-01

The murine data presented illustrate the influence of food consumption on the proliferative rate of the oesophageal epithelium during recovery from radiation damage. Refeeding at a time before the initiation of the normal hyperplastic response results in a decreased time interval between treatment and increased rates of cell proliferation, while reduced food consumption during the normal period of hyperproliferation results in reduced proliferative activity. The finding that recovery kinetics may be altered by changing food consumption patterns should be an important consideration in the analysis of antineoplastic agent-induced proliferative perturbations, as many treatments themselves produce reduced levels of food consumption.

The purpose of this study was to investigate the relationship between coffee consumption and the risk of metabolic syndrome in Korean adults based on the 2010 Korean National Health and Nutrition Examination Survey (KNHANES V-1. Methods: Dietary intake status and the factors of metabolic syndrome were assessed. Three groups (no coffee consumption, moderate intake, and high intake were divided into tertile according to black coffee cream (include brewed coffee consumption per day. Results: Our results showed that the Tertile 3 group consumed more calories from fat, and niacin was higher than in the Tertile 1 and Tertile 2 group. INQ for protein and vitamin B1 was significantly higher in no coffee consumption group than the other groups and in Tertile 3 exhibited significantly higher niacin intake. The subjects in Tertile 3 showed significantly higher consumption in grain and oil intake, and Tertile 1 group showed higher consumption in milk and dairy products. In the logistic regression analysis, adjusting for sex, age, energy intake, smoking, and drinking, being in the high coffee consumption group (Tertile 3 was significantly and inversely associated with abdominal obesity (OR = 0.76, CI = 0.71–0.82, hypertension (OR = 0.70, CI = 0.54–0.87, high glucose(OR =  0.71, CI = 0.61–0.86.

Healthy eating during early childhood is important for growth and development. Eating Well with Canada's Food Guide (CFG) provides dietary recommendations. We investigated patterns of food consumption among preschool children and attempted to determine whether these children's intakes met nutrition recommendations. Between 2005 and 2007, four- and five-year-old children (n=2015) attending 12 Edmonton-region public health units for immunization were recruited for a longitudinal study on determinants of childhood obesity. The children's dietary intake at baseline was assessed using parental reports. Overall, 29.6%, 23.5%, 90.9%, and 94.2% of the children met recommendations for vegetables and fruit, grain products, milk and alternatives, and meat and alternatives, respectively. In addition, 79.5% consumed at least one weekly serving of foods in the "choose least often" group. Significant differences existed in consumption of food groups across socioeconomic and demographic groups. For example, 82.9%, 84.7%, and 75.9% of preschool children from neighbourhoods of low, medium, and high socioeconomic status, respectively, consumed at least one food in the "choose least often" group (χ² =16.2, pConsumption of vegetables and fruit and grain products was low among participants, and intake of "choose least often" foods was high. Consumption of foods also differed among socioeconomic and demographic groups. To encourage healthy eating among children, public health professionals should target groups who do not meet the CFG recommendations.

The relationship between diet and health has aroused scientific interest, especially the consumption of antioxidant nutrients naturally present in foods, because of its action against the deleterious effects of free radicals in the body. This study aimed to estimate the intake of antioxidant nutrients and its relationship with lipid profile and oxidative stress in student users of a university restaurant in comparison with non-users. This cross-sectional study involved 145 university students divided into two groups: users of the university restaurant (group 1, n = 73) and non-users (group 2, n = 72). We measured body mass index and waist circumference, and estimated the intake of antioxidant micronutrients. Serum concentrations of total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and triglyceride levels, and plasma concentrations of malondialdehyde were determined. Intake of copper, zinc, selenium, and vitamin C were within the recommendations in both groups, and vitamins A and E were below the reference values. There was a correlation between the intake of vitamin C and triglycerides. Group 1 members had better dietary patterns in relation to antioxidant micronutrients, reflecting less atherogenic lipid profile and lower exposure to oxidative stress compared to group 2.

Manure nitrogen (N) and phosphorus (P) from livestock husbandry are important components of terrestrial biogeochemical cycling. Assessment of the impacts of livestock manure on terrestrial biogeochemistry requires a compilation and analysis of spatial and temporal patterns of manure nutrients. In this study, we reconstructed county-level manure nutrient data of the conterminous United States (U.S.) in 4- to 5-year increments from 1930 to 2012. Manure N and P were 5.89 ± 0.64 Tg N yr.{sup −1} (Mean ± Standard Deviation) and 1.73 ± 0.29 Tg P yr.{sup −1} (1 Tg = 10{sup 12} g), and increased by 46% and 92% from 1930 to 2012, respectively. Prior to 1970, manure provided more N to the U.S. lands than chemical fertilizer use. Since 1970, however, increasing chemical N fertilizer use has exceeded manure N production. Manure was the primary P source in the U.S. during 1930–1969 and 1987–2012, but was lower than P fertilizer use in 1974, 1978, and 1982. High-nutrient-production regions shifted towards eastern and western areas of the U.S. Decreasing small farms and increasing Concentrated Animal Feeding Operations (CAFOs) induced concentrated spatial patterns in manure nutrient loads. Counties with cattle or poultry as the primary manure nutrient contributors expanded significantly from 1930 to 2012, whereas regions with sheep and hog as the primary contributors decreased. We identified regions facing environmental threats associated with livestock farming. Effective management of manure should consider the impacts of CAFOs in manure production, and changes in livestock population structure. The long-term county-level manure nutrient dataset provides improved spatial and temporal information on manure nutrients in the U.S. This dataset is expected to help advance research on nutrient cycling, ammonia volatilization, greenhouse gas (GHG) emissions from livestock husbandry, recovery and reuse of manure nutrients, and impacts of livestock feeding on human health in

Few longitudinal population-based cohort studies of older people have described dietary intakes over time. The objective of this study was to assess changes in the food and nutrient intake in a cohort of older Australians, using longitudinal data collected over 10 years. Population-based cohort of people aged 49 years and over at baseline (82% of those eligible) living in two postcode areas, west of Sydney. In 1992-1994, 3654 people were examined; 2334 were reexamined after 5 years and 1952 after 10 years (75% survivors at both examinations). A 145-item food frequency questionnaire was used to assess food and nutrient intake on each occasion, and 1166 participants provided usable dietary data at all three examinations. Energy and sugar intake significantly increased among women over the 10-year period (P-value for trend bread consumption decreased in both men and women (P-value for trend choices. This information could be used to inform nutrition policy and programs targeted to older persons. These data highlight the need to identify barriers to better food choices.

The dietary pattern of the population has shifted in recent years as a result of cultural changes and modifications in food accessibility. In order to describe the changes in food and beverage consumption patterns in the last two decades in Argentina, the National Survey of Household Expenditure [Encuesta Nacional de Gastos de los Hogares] was analyzed for the periods 1996-1997, 2004-2005 and 2012-2013. The average apparent consumption of food and beverages in grams or milliliters of net weight per adult equivalent was estimated for each period. The variation in the amount of food and beverages available for consumption between 1996 and 2013 shows that the structure of the dietary pattern has changed, appearing to indicate shifts in the ways of buying, preparing and consuming foods related to greater convenience and accessibility and less time spent on food preparation.

This research tested the associations between caregiver feeding styles and children's food consumption patterns among African-American (AA) and Hispanic (H) caregivers and their preschool children. Participants were 231 caregivers (101 AA; 130 H) with children enrolled in Head Start. Caregivers completed questionnaires on authoritarian and authoritative feeding styles (Caregiver's Feeding Styles Questionnaire; CFSQ) and various aspects of children's food consumption patterns (availability of, feeding attempts for, and child's consumption of dairy, fruit, and vegetables). Simultaneous multiple regression analyses tested the unique contribution of feeding styles in predicting food consumption patterns. Authoritative feeding was positively associated whereas authoritarian feeding was negatively associated with the availability of fruit and vegetables. Authoritative feeding was also positively associated with attempts to get the child to eat dairy, fruit, and vegetables, and reported child consumption of dairy and vegetables. Authoritarian feeding was negatively associated with child's vegetable consumption. All results remained significant after controlling for child's gender and body mass index (BMI), and caregiver's ethnicity, BMI, and level of education. Overall, results provide evidence for the benefits of authoritative feeding and suggest that interventions to increase children's consumption of dairy, fruit, and vegetables should be targeted toward increasing caregivers' authoritative feeding behaviors.

We reviewed the MR appearances of six cases of longitudinal stress fracture of the lower extremity.Results. One fracture was in the femur and five were in the tibia. Four of the tibial fractures showed edema starting in the mid-tibia at the level of the nutrient foramen with the fracture on the anteromedial cortex. The other tibial fracture started at the nutrient foramen. Three fractures (two tibial and the femur fracture) showed eccentric marrow edema; all fractures showed either eccentric periosteal reaction or soft tissue edema.Conclusion. Primary diagnosis of longitudinal stress fracture is made by finding a vertical cleft on one or more axial images. Secondary signs of position of the nutrient foramen and patterns of edema may be useful. (orig.)

The role of diet on colorectal cancer has been considered in terms of single foods and nutrients, but less frequently in terms of dietary patterns. Data were derived from an Italian case-control study, including 1,225 subjects with cancer of the colon, 728 subjects with rectal cancer, and 4,154 hospital controls. We identified dietary patterns on a selected set of nutrients through principal component factor analysis. Odds ratios (OR) and 95% confidence intervals for both cancers were estimated using unconditional multiple logistic regression. We identified 5 major dietary patterns. Direct associations were observed between the Starch-rich pattern and both cancer of the colon (OR = 1.68) and of the rectum (OR = 1.74). Inverse relationships were found between the Vitamins and fiber pattern and rectal cancer (OR = 0.61), between the Unsaturated fats (animal source) and the Unsaturated fats (vegetable source) and cancer of the colon (OR = 0.80 and OR = 0.79, respectively). No other significant association was found. The Starch-rich pattern is potentially an unfavorable indicator of risk for both colon and rectal cancer, whereas the Vitamins and fiber pattern is associated with a reduced risk of rectal cancer and the Unsaturated fats patterns with a reduced risk of colon cancer.

The carbon consumption pattern of the spoilage yeast Brettanomyces bruxellensis in synthetic wine-like medium.

The wine matrix contains limited carbon compounds to sustain microbial life. Brettanomyces bruxellensis is one of very few yeast species that has adapted to this environment. Indeed, the presence of growth-inhibiting compounds and conditions do not prevent its proliferation. Literature regarding the nutritional requirements of this yeast is surprisingly poor, given the observation that B. bruxellensis produces biomass with apparently less nutrients than other yeasts. In this study, various carbon sources were screened in a synthetic wine medium, under anaerobic and semi-aerobic growth conditions, in order to determine which compounds B. bruxellensis assimilates. Slight differences were observed between strains but overall, B. bruxellensis produced biomass from limited nutrients consumed in a specific order regardless of the oxygen conditions. Upon initial consumption of the simple sugars, B. bruxellensis was able to remain viable, by concurrently utilising ethanol (only in the presence of oxygen) and malic acid. Although initially beneficial, oxygen was found detrimental in the long term. Formation of volatile phenols occurred during the consumption of the sugars but not as a mechanism to help correct the redox imbalance. The study confirms that B. bruxellensis is able to survive using limited amount of nutrients, making this yeast a challenge for winemakers. Copyright © 2017 Elsevier Ltd. All rights reserved.

2015-10-01

In order to assess the qualitative pattern of food consumption in urban families of Anzoátegui, Venezuela, 300 domestic groups that combined a total of 1 163 people were studied. The domestic dietary pattern was addressed by the method of qualitative frequency of food consumption, which applied a structured survey that yielded the usual frequency of intake of a food or food group over a given period. The information was obtained through an interview with the person responsible for the procurement of food in every home, and included basic data for the socioeconomic and nutritional profile of the families studied. The qualitative analysis of the diet was obtained by comparing the different food groups that constitute the actual consumption pattern of the population studied, with official feeding guidelines suggested for the Venezuelan population. The present study showed that the qualitative pattern of food consumption in the urban population evaluated is characterized by slightly adjusted to the promotion of health and control of diet-related diseases. The family food proved to be far from the guidelines established by the dietary guidelines for Venezuela and consumption patterns are fairly homogeneous in the different socioeconomic strata. The foods most consumed daily were salt, coffee, dressing and precooked corn flour as well as beef, chicken and the higher weekly food consumption pastas. 90% of the food consumed daily is technologically processed. The results contribute to increase knowledge about the food situation of the Venezuelan population, and technically could direct the efforts of the authorities to reconcile the development of the productive sector and food supply, whereas a pattern qualitatively inadequate intake directly affects the individual biological functioning, and results in the collective conditioning of unfavorable health states.

A pooled analysis of seven cross-sectional studies from Newfoundland and Labrador, Waterloo and Hamilton Regions, Ontario and Vancouver, East Kootenay and Northern Interior Regions, British Columbia (2001 to 2007) was performed to investigate the drinking water consumption patterns of Canadians and to identify factors associated with the volume of tap water consumed. The mean volume of tap water consumed was 1.2 L/day, with a large range (0.03 to 9.0 L/day). In-home water treatment and interactions between age and gender and age and bottled water use were significantly associated with the volume of tap water consumed in multivariable analyses. Approximately 25% (2,221/8,916) of participants were classified as bottled water users, meaning that 75% or more of their total daily drinking water intake was bottled. Approximately 48.6% (4,307/8,799) of participants used an in-home treatment method to treat their tap water for drinking purposes. This study provides a broader geographic perspective and more current estimates of Canadian water consumption patterns than previous studies. The identified factors associated with daily water consumption could be beneficial for risk assessors to identify individuals who may be at greater risk of waterborne illness.

A survey on daily consumption pattern, i.e. carbohydrate, animal and plant proteins, vegetables, and fruits for people in Java Island has been done. The survey was conducted by interviewing using a questionare and food models. The results showed that the daily consumption of carbohydrates, animal protein, plant protein, vegetables and fruits sources are 631.34 + 38.42 g, 136.96 + 3.36 g, 107.46 + 7.15 g, 124.33 + 11.29 and 136.76 + 33.8 g, respectively. The average amount of daily food consumption for man is higher than women. The analysis of nutrition content showed that animal protein is higher consumed by man than women, whereas plant protein is higher consumed by women than men. The highest daily consumption for women is in sub-urban area and those for men is in agricultural area. If it is related to upper arm circumference and body weight, the nutrition grade for all respondences is in normal range. From this survey the rate of intake of radionuclides contained in foodstuff can also be determined and the sensitivity of people to radiation effect that could be resulted the health consequences can be estimated

How does pattern of feeding and rate of nutrient delivery influence conditioned food preferences?

Ruminant herbivores have been shown to learn about food properties by associating food flavours with the food's post-ingestive consequences. Previous experimentation supporting the conditioned food aversion/preference hypothesis has generally employed very simple diet learning tasks which do not effectively represent the wide range of foods selected within single bouts typical of wild, free-ranging ruminant herbivores. We tested the ability of a ruminant herbivore to associate a food with artificially administered nutrient rewards in a designed experiment where we altered the temporal pattern of encounter with the food as well as the nature (fast or slow reward) of the post-ingestive outcome. Twenty-four goats were offered branches of Sitka spruce (SS) and Norway spruce (NS) for 4 h per day on two days per week for five weeks. The pattern of feeding varied with treatment such that the species on offer changed every hour (short) or every 2 h (long). The energy treatment altered the reward delivered during Sitka consumption so that animals were dosed either with predominantly sugar (rapidly fermented), predominantly starch (slower fermentation rate), or with water (placebo). Preference was measured on the day following each learning day. We expected that goats would find it easier to associate SS with post-ingestive rewards when the duration of encounter was longest, and that associations would be stronger with the most rapidly digested post-ingestive reward. In the event, goats did not alter their consumption of SS in response to the treatments. Our results suggest that at the scale of temporal resolution of encounters with different plant species (1-2 h), and at the different rates of experiencing post-ingestive consequences tested in this experiment, ruminants do not appear to discriminate the nutritive properties of foods predominantly through a post-ingestive feedback mechanism. They must, instead, use a range of cues-including post-ingestive consequences

In order to explore the role of nutrients and bioactive related substances in colorectal cancer, we conducted a case-control in Uruguay, which is the country with the highest production of beef in the world. Six hundred and eleven (611) cases afflicted with colorectal cancer and 1,362 controls drawn from the same hospitals in the same time period were analyzed through unconditional multiple logistic regression. This base population was submitted to a principal components factor analysis and three factors were retained. They were labeled as the meat-based, plant-based, and carbohydrates patterns. They were rotated using orthogonal varimax method. The highest risk was positively associated with the meat-based pattern (OR for the highest quartile versus the lowest one 1.63, 95 % CI 1.22-2.18, P value for trend = 0.001), whereas the plant-based pattern was strongly protective (OR 0.60, 95 % CI 0.45-0.81, P value for trend pattern was only positively associated with colon cancer risk (OR 1.46, 95 % CI 1.02-2.09). The meat-based pattern was rich in saturated fat, animal protein, cholesterol, and phosphorus, nutrients originated in red meat. Since herocyclic amines are formed in the well-done red meat through the action of amino acids and creatine, it is suggestive that this pattern could be an important etiologic agent for colorectal cancer.

2011-05-01

Besides providing n-3 fatty acids with nutritional and health benefits, seafood consumption may contribute to the reduction of nutrient prevalences of inadequacy. To evaluate the contributions of seafood and other food groups to nutrient intakes of frequent seafood consumers, food consumption was evaluated through an FFQ on 991 French men and women (18-81 years) consuming seafood at least twice a week. Intakes, prevalence of inadequacies, risks of upper limit excess and food contributions to intakes were assessed for thirty-three nutrients. Mean fat contributions to total energy intakes (38·3 and 39·0 % for men and women, respectively) met French recommendations, but mean carbohydrate intakes (40·9 and 39·7 %, respectively) were insufficient. Micronutrient inadequacies were lower than in the French general population, the highest being for vitamin C (41·3 and 40·1 % for men and women, respectively), vitamin E (35·0 and 35·3 % for men and women, respectively) and Mg (37·5 and 25·5 % for men and women, respectively). Upper safety limits (USL) were exceeded mostly for Zn (6·2 %), Ca (3·7 %), retinol (2·0 %) and Cu (0·9 %). Mean contributions of seafood to vitamin D, B12, I and Se intakes ranged 40-65 %. Molluscs and crustaceans significantly contributed to vitamin B12 (13·7 %), Cu (11·4 %), Fe (11·5 %), Zn (8·4 %) and I (6·1 %) intakes, and canned fish contributed to vitamin D intake (13·4 %). Besides fish, contributions of mollusc and crustacean consumption to nutrient intakes should be considered from a public health viewpoint. Consuming seafood at least twice a week induces moderate inadequacies and risks of exceeding USL for some micronutrients, whereas macronutrient intakes remained imbalanced.

The aims of the present work were to study motives underlying Uruguayan consumers' food choice behaviour and to study the consumption frequency of some selected food items. A modification of the Food Choice Questionnaire and a food frequency questionnaire was administered to a group of 200 Uruguayan consumers. Feeling good and safety, sensory appeal and health and nutrient content were rated as the most important factors, while familiarity was rated as the least important. Using hierarchical cluster analysis, three clusters with different choice patterns were identified. Frequency of consumption of fruits, vegetables, milk and dairy products, and whole cereals, increased as the importance attributed to health and nutrition increased; consumption of fatty foods decreased.

Respondents reporting consumption of any amount of grapefruit or 100% grapefruit juice at least once during the 2 days of dietary recall were classified as grapefruit consumers. Results: Among adults aged 19+ years with 2 days of dietary recall (n=12,789, 2.5% of males and 2.7% of females reported consumption of 100% grapefruit juice or fresh, canned, or frozen grapefruit during the recalls. Grapefruit consumers were less likely to have usual intakes of vitamin C (males: 0% vs. 47%; females: 0% vs. 43%; P<0.001 and magnesium (P<0.05 below the estimated average requirement (EAR compared to non-consumers, and they were more likely to meet adequate intake levels for dietary fiber (P<0.05. Potassium and β-carotene intakes were significantly higher among grapefruit consumers (P<0.001. Diet quality as assessed by the Healthy Eating Index-2005 (HEI-2005 was higher in grapefruit consumers (males: 66.2 [95% CI: 61.0–71.5] vs. 55.4 [95% CI: 54.4–56.4]; females: 71.4 [95% CI: 65.1–77.6] vs. 61.2 [95% CI: 59.8–62.6]. Among women, grapefruit consumption was associated with lower body weight, waist circumference, body mass index (BMI, triglycerides, C-reactive protein (CRP, and higher high-density lipoprotein (HDL cholesterol (P<0.05, However, risk of being overweight/obese was not associated with grapefruit consumption. Conclusion: Consumption of grapefruit was associated with higher intakes of vitamin C, magnesium, potassium, dietary fiber, and improved diet quality

This study describes food consumption patterns in Canada according to the types of food processing using the Nova classification and investigates the association between consumption of ultra-processed foods and the nutrient profile of the diet. Dietary intakes of 33,694 individuals from the 2004 Canadian Community Health Survey aged 2 years and above were analyzed. Food and drinks were classified using Nova into unprocessed or minimally processed foods, processed culinary ingredients, processed foods and ultra-processed foods. Average consumption (total daily energy intake) and relative consumption (% of total energy intake) provided by each of the food groups were calculated. Consumption of ultra-processed foods according to sex, age, education, residential location and relative family revenue was assessed. Mean nutrient content of ultra-processed foods and non-ultra-processed foods were compared, and the average nutrient content of the overall diet across quintiles of dietary share of ultra-processed foods was measured. In 2004, 48% of calories consumed by Canadians came from ultra-processed foods. Consumption of such foods was high amongst all socioeconomic groups, and particularly in children and adolescents. As a group, ultra-processed foods were grossly nutritionally inferior to non-ultra-processed foods. After adjusting for covariates, a significant and positive relationship was found between the dietary share of ultra-processed foods and the content in carbohydrates, free sugars, total and saturated fats and energy density, while an inverse relationship was observed with the dietary content in protein, fiber, vitamins A, C, D, B6 and B12, niacin, thiamine, riboflavin, as well as zinc, iron, magnesium, calcium, phosphorus and potassium. Lowering the dietary share of ultra-processed foods and raising consumption of hand-made meals from unprocessed or minimally processed foods would substantially improve the diet quality of Canadian.

This study reports the food consumption patterns of adults aged 18 to 59 years in the Malaysian Adults Nutrition Survey (MANS) carried out between October 2002 and December 2003. A total of 6,742 subjects comprising 3,274 men and 3,468 women representing the northern, central , southern and east coast of Peninsular Malaysia as well as Sabah and Sarawak were interviewed. A semiquantitative food frequency questionnaire (FFQ) which consisted of 126 food items was used to evaluate the food consumption pattern (habitual food intake) of the respondents during the previous one- year period. The results demonstrate that nasi putih (cooked rice) was consumed by 97% of the population twice daily (average 2½ plates per day). Other food items consumed daily were marine fish, (one medium fish per day), green leafy vegetables (one cup per day) and sweetened condensed milk (three teaspoons per day. The mean frequencies for daily intake of rice, leafy vegetables, marine fish, local kuih, anchovy (ikan bilis) and biscuits were significantly higher among the rural compared to the urban adults. In contrast, more urban dwellers consumed chicken and eggs more frequently than their rural counterparts. More men than women consumed chicken and eggs more frequently. Malaysian adults showed a satisfactory habit of drinking plain water, with 99% drinking at least six glasses of plain water daily. Other beverages such as tea (47%), coffee (28%), chocolate-based drinks (23%) and cordial syrup (11%) were also consumed on daily basis, however, in a smaller proportion of the population. There were differences in the prevalence of daily consumption of foods when comparing urban and rural population, and also between men and women. The prevalence of daily consumption of marine fish among rural and urban adults was 51% and 34% respectively. For sweetened condensed milk, men and women consumed 43% and 28% respectively; however, more women drank full cream milk than men. Between the age groups, 21

Effects of thermal discharges on the seasonal patterns of nutrient concentrations in brackish water

International Nuclear Information System (INIS)

1985-05-01

Massiv quantities of water are used in power plant cooling systems, especially nuclear power plants, and are often returned to the donor ecosystem at significantly elevated temperatures. Few studies of the environmental effects of such a situation have looked extensively at the effects on nutrients in the water. The present study examined the effects of cooling water discharges from a nuclear power plant on the seasonal nutrient patterns within and outside a brackish water, research artificial lake, the 0.9 km 2 Biotest Basin on Sweden's east coast. The lack of ice cover in winter is the most apparent effect. In a portion of the lake with a relatively long water residence time, on the order of a few days, the vernal nutrient depletion of phosphate, nitrate, and nitrite apparently began sooner than outside the lake. Benthic influence on nutrient concentrations in the free water mass may be very significant in coastal areas receiving heat inputs. This study's data apparently support the conclusion by other researchers that phosphorus may be the nutrient limiting algal growth in the spring in this area of the central Baltic Sea. Determination of a nutrient budget for the Basin was unachievable because inlet and outlet nutrient concentrations were insufficiently different to override experimental variation. Implications for management of heat inputs to coastal ecosystems include avoidance of areas with high nutrient content, rich organic sediment, or poor flushing. (author)

The present study tests the hypothesis that higher consumption of bakery products, sweetened soft drinks and yogurt is associated with higher intake of energy, saturated fats, sugars and worse overall diet quality among Spanish children. This is a cross-sectional study covering 1112 children aged 6.0-7.0 years in four Spanish cities. Nutrient and food intake were obtained through a food-frequency questionnaire, and overall diet quality calculated using the healthy-eating index (HEI) developed by Kennedy et al. (1995). Standardized methods were used to measure anthropometric variables. Associations of interest were summarized as the difference in nutrient and food consumption between the value of the fifth and the first quintile of consumption (dq) of bakery products, sweetened soft drinks or yogurt, adjusted for energy intake and BMI. Bakery products, sweetened soft drinks and yogurt supplied 15.5, 1.0 and 5.6 % energy intake respectively. Higher consumption of these three foods was associated with greater energy intake (Pbakery products was associated with the proportion of energy derived from intake of total carbohydrates (dq 4.5 %, Pbakery products, sweetened soft drinks and yogurt were usually very small. We conclude that the impact of the consumption of bakery products, sweetened soft drinks and yogurt on the quality of the diet of Spanish children is only modest, although it may contribute to aggravating certain unhealthy characteristics of their diet, particularly excess energy, saturated fats and sugars. Therefore, consumption of bakery products and sweetened soft drinks should be moderated, and priority given to consumption of low-fat, low-sugar yogurt.

Manure nitrogen (N) and phosphorus (P) from livestock husbandry are important components of terrestrial biogeochemical cycling. Assessment of the impacts of livestock manure on terrestrial biogeochemistry requires a compilation and analysis of spatial and temporal patterns of manure nutrients. In this study, we reconstructed county-level manure nutrient data of the conterminous United States (U.S.) in 4- to 5-year increments from 1930 to 2012. Manure N and P were 5.8 9 ± 0.64 Tg N yr.(-1) (Mean ± Standard Deviation) and 1.73 ± 0.29 Tg Pyr.(-1) (1 Tg = 10(12)g), and increased by 46% and 92% from 1930 to 2012, respectively. Prior to 1970, manure provided more N to the U.S. lands than chemical fertilizer use. Since 1970, however, increasing chemical N fertilizer use has exceeded manure N production. Manure was the primary P source in the U.S. during 1930-1969 and 1987-2012, but was lower than P fertilizer use in 1974, 1978, and 1982. High-nutrient-production regions shifted towards eastern and western areas of the U.S. Decreasing small farms and increasing Concentrated Animal Feeding Operations (CAFOs) induced concentrated spatial patterns in manure nutrient loads. Counties with cattle or poultry as the primary manure nutrient contributors expanded significantly from 1930 to 2012, whereas regions with sheep and hog as the primary contributors decreased. We identified regions facing environmental threats associated with livestock farming. Effective management of manure should consider the impacts of CAFOs in manure production, and changes in livestock population structure. The long-term county-level manure nutrient dataset provides improved spatial and temporal information on manure nutrients in the U.S. This dataset is expected to help advance research on nutrient cycling, ammonia volatilization, greenhouse gas (GHG) emissions from livestock husbandry, recovery and reuse of manure nutrients, and impacts of livestock feeding on human health in the context of global

We conducted a case-control study to investigate the effect of diet on laryngeal carcinogenesis. Our study population was made up of 140 participants-70 patients with laryngeal cancer (LC) and 70 controls with a non-neoplastic condition that was unrelated to diet, smoking, or alcohol. A food-frequency questionnaire determined the mean consumption of 113 different items during the 3 years prior to symptom onset. Total energy intake and cooking mode were also noted. The relative risk, odds ratio (OR), and 95% confidence interval (CI) were estimated by multiple logistic regression analysis. We found that the total energy intake was significantly higher in the LC group (p pastas) was also higher among the LC patients (p = 0.043), with logistic regression analysis showing that their negative effect was possibly associated with the sauces and dressings that traditionally accompany pasta dishes (p = 0.006; OR: 4.78). Conversely, a higher consumption of dairy products was found in controls (p < 0.05); logistic regression analysis showed that calcium appeared to be protective at the micronutrient level (p < 0.001; OR: 0.27). We found no difference in the overall consumption of fruits and vegetables between the LC patients and controls; however, the LC patients did have a greater consumption of cooked tomatoes and cooked root vegetables (p = 0.039 for both), and the controls had more consumption of leeks (p = 0.042) and, among controls younger than 65 years, cooked beans (p = 0.037). Lemon (p = 0.037), squeezed fruit juice (p = 0.032), and watermelon (p = 0.018) were also more frequently consumed by the controls. Other differences at the micronutrient level included greater consumption by the LC patients of retinol (p = 0.044), polyunsaturated fats (p = 0.041), and linoleic acid (p = 0.008); LC patients younger than 65 years also had greater intake of riboflavin (p = 0.045). We conclude that the differences in dietary consumption patterns between LC patients and controls

Socio-cultural and economic factors affecting food consumption patterns in the Arab countries.

Musaiger, A O

Several factors have been found to determine the dietary habits of the people in the Arab world. Food consumption pattern has dramatically changed in some Arab countries as a result of sudden increase in income from oil revenue. It is believed that food subsidy policy has adversely affected the food habits in the Gulf states by encouraging the intake of fat, sugar, rice, wheat flour and meat. Socio-cultural factors such as religion, beliefs, food preferences, gender discrimination, education and women's employment all have a noticeable influence on food consumption patterns in this region. Mass media, especially televised food advertisements, play an important role in modifying the dietary habits. The migration movement, particularly that which was carried out during the 70s has a great impact on the food practices in many Arab countries. Comprehensive studies on social, cultural and economic factors associated with food consumption patterns in the Arab region are highly recommended.

To determine the pattern of consumption of Imbrasia belina (madora) and other edible insects and also compare the nutrient values of madora larvae and two of its variants (Anaphe venata and Cirina forda) to those of some conventional sources of protein. University of Zimbabwe. 100 workers who admitted to a history of entomophagy. Popularity score of madora compared with those of other edible insects and approximate compositions of nutrients in the larvae compared with standard proteins. Most respondents (65%) were introduced to entomophagy by their parents. Termites were the most frequently consumed, followed by madora. More respondents ate insects because of their perceived nutritional value than because of their relative availability. There was no association of entomophagy with significant side effects. The protein, fat and mineral contents of the larvae were superior to those of beef and chicken. There were no major differences in the nutrient composition of the three Lepidoptera variants. The high nutrient value and low cost of these larvae make them an important protein supplement, especially for people in the low income group.

Do changes in per capita consumption mirror changes in drinking patterns?

Smart, R G; Suurvali, H M; Mann, R E

2000-07-01

The goal of this study was to examine how well per capita alcohol consumption figures derived from beverage sales data relate to changes over time in survey-based measures of drinking patterns. It was expected that strong associations would be found among these various measures of consumption. Data from 12 household surveys conducted in Ontario between 1977 and 1997 provided information on: percentages of drinkers; daily drinkers; those drinking five or more drinks at a sitting weekly; those reporting two or more alcohol-related harms; and average number of drinks per week. These variables were then correlated with per capita consumption. Significant correlations were found only between per capita consumption and percentage of daily drinkers, and between percentage of drinkers and average number of drinks per week. The relationship of per capita consumption to survey measures of drinking is weak. The absence of consistent associations over time between per capita consumption and survey measures may be attributable to the small number of available data points or to increases in unrecorded consumption. Further research is needed to verify and explain these results.

Consumption of 100% fruit juice remains controversial for its potential adverse impact on weight and displacement of essential foods in the diets of children. A systematic review of the literature published from 1995-2013 was conducted using the PubMed database to evaluate associations between intake of 100% fruit juice and weight/adiposity and nutrient intake/adequacy among children of 1 to 18 years of age. Weight status outcome measures included body mass index (BMI), BMI z-score, ponderal index, obesity, weight gain, adiposity measures, and body composition. Nutrient outcome measures included intake and adequacy of shortfall nutrients. Data extraction and analysis was conducted according to the Academy of Nutrition and Dietetics Evidence Analysis Process. Twenty-two studies on weight status provided evidence that did not support an association between 100% fruit juice consumption and weight/adiposity in children after controlling for energy intake. Limited evidence from eight studies suggests that children consuming 100% fruit juice have higher intake and adequacy of dietary fiber, vitamin C, magnesium, and potassium. Differences in methodology and study designs preclude causal determination of 100% fruit juice as sole influencer of weight status or nutrient intake/adequacy of shortfall nutrients. In context of a healthy dietary pattern, evidence suggests that consumption of 100% fruit juice may provide beneficial nutrients without contributing to pediatric obesity.

Watermelon (Citrullus lanatus L.) originates from arid regions of southern Africa, and its fruit contains a large amount of the amino acid citrulline, an efficient hydroxyl radical scavenger. Citrulline is implicated in the production of nitric oxide in human endothelium, and potential health benefits including vasodilatation and antioxidant functions have been suggested. However, citrulline metabolism in watermelon fruits is poorly understood. This study examined the accumulation pattern of citrulline and other nutrients in immature and mature watermelon fruits. In mature fruits, highest citrulline concentration was observed in the outer peel, followed by the central portion of the flesh and inner rinds, whereas the level was lower in the peripheral portion of the flesh. Citrulline content was generally low in immature fruits. Spatial and developmental patterns of citrulline accumulation were largely different from those of the antioxidant lycopene, total proteins, and soluble sugars such as glucose, fructose, and sucrose. Principal component analysis suggested a clear distinction of the central flesh and outer peels in mature fruits from other tissues in terms of the levels of major nutrients. These observations suggested that citrulline accumulation may be regulated in a distinct manner from other nutrients during watermelon fruit maturation. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

Poor feeding practices result in inadequate nutrient intakes in young children in developing countries. To improve practices, local food-based complementary feeding recommendations (CFR) are needed. This cross-sectional survey aimed to describe current food consumption patterns of 12-23-month-old Myanmar children (n 106) from Ayeyarwady region in order to identify nutrient requirements that are difficult to achieve using local foods and to formulate affordable and realistic CFR to improve dietary adequacy. Weekly food consumption patterns were assessed using a 12-h weighed dietary record, single 24-h recall and a 5-d food record. Food costs were estimated by market surveys. CFR were formulated by linear programming analysis using WHO Optifood software and evaluated among mothers (n 20) using trial of improved practices (TIP). Findings showed that Ca, Zn, niacin, folate and Fe were 'problem nutrients': nutrients that did not achieve 100 % recommended nutrient intake even when the diet was optimised. Chicken liver, anchovy and roselle leaves were locally available nutrient-dense foods that would fill these nutrient gaps. The final set of six CFR would ensure dietary adequacy for five of twelve nutrients at a minimal cost of 271 kyats/d (based on the exchange rate of 900 kyats/USD at the time of data collection: 3rd quarter of 2012), but inadequacies remained for niacin, folate, thiamin, Fe, Zn, Ca and vitamin B6. TIP showed that mothers believed liver and vegetables would cause worms and diarrhoea, but these beliefs could be overcome to successfully promote liver consumption. Therefore, an acceptable set of CFR were developed to improve the dietary practices of 12-23-month-old Myanmar children using locally available foods. Alternative interventions such as fortification, however, are still needed to ensure dietary adequacy of all nutrients.

Big Data Analytics for Discovering Electricity Consumption Patterns in Smart Cities

Full Text Available New technologies such as sensor networks have been incorporated into the management of buildings for organizations and cities. Sensor networks have led to an exponential increase in the volume of data available in recent years, which can be used to extract consumption patterns for the purposes of energy and monetary savings. For this reason, new approaches and strategies are needed to analyze information in big data environments. This paper proposes a methodology to extract electric energy consumption patterns in big data time series, so that very valuable conclusions can be made for managers and governments. The methodology is based on the study of four clustering validity indices in their parallelized versions along with the application of a clustering technique. In particular, this work uses a voting system to choose an optimal number of clusters from the results of the indices, as well as the application of the distributed version of the k-means algorithm included in Apache Spark’s Machine Learning Library. The results, using electricity consumption for the years 2011–2017 for eight buildings of a public university, are presented and discussed. In addition, the performance of the proposed methodology is evaluated using synthetic big data, which cab represent thousands of buildings in a smart city. Finally, policies derived from the patterns discovered are proposed to optimize energy usage across the university campus.

Food consumption patterns and their effect on water requirement in China

Directory of Open Access Journals (Sweden)

J. Liu

2008-06-01

Full Text Available It is widely recognized that food consumption patterns significantly impact water requirements. The aim of this paper is to quantify how food consumption patterns influence water requirements in China. The findings show that per capita water requirement for food (CWRF has increased from 255 m³ cap^-1y⁻¹ in 1961 to 860 m³ cap^-1 y⁻¹ in 2003, largely due to an increase in the consumption of animal products in recent decades. Although steadily increasing, the CWRF of China is still much lower than that of many developed countries. The total water requirement for food (TWRF has been determined as 1127 km³ y^-1 in 2003. Three scenarios are proposed to project future TWRF, representing low, medium, and high levels of modernization (S1, S2, and S3, respectively. Analysis of these three scenarios indicates that TWRF will likely continue to increase in the next three decades. An additional amount of water ranging between 407 and 515 km³ y^-1 will be required in 2030 compared to the TWRF in 2003. This will undoubtedly put high pressure on China's already scarce water resources. We conclude that the effect of the food consumption patterns on China's water resources is substantial both in the recent past and in the near future. China will need to strengthen "green water" management and to take advantage of "virtual water" import to meet the additional TWRF.

Long-term seasonal nutrient limiting patterns at Meiliang Bay in a large, shallow and subtropical Lake Taihu, China

Full Text Available Lake Taihu has undergone severe eutrophication in the past three decades, and harmful cyanobacteria blooms occur nearly every year in Meiliang Bay at the north end of the lake. To elucidate the potential relationship between seasonal nutrient limitation and phytoplankton proliferation, a 20-year (1991-2012 time series of nutrient limitation in Meiliang Bay was analyzed for deviations between trophic state index (TSI parameters. Results showed that patterns of nutrient limitation in Meiliang Bay were distinctly seasonal, where phytoplankton growth was generally phosphorus (P-limited in winter and spring, but nitrogen (N-limited mainly occurred in summer and fall. This general pattern, however, shifted into N limitation across the four seasons during the mid-1990s because a rapid increase in industrialization led to a significant rise in the input of N and P from inflowing tributaries. The initial patterns were restored by environmental regulation in the end of 1990s, including the Zero Actions plan. Using routine monitoring data, a generalised additive model (GAM with time and deviations between trophic state indexes for nitrogen and phosphorus (TSIN-TSIP as explanatory variables was used to explore which nutrient was responsible for limitation of phytoplankton chlorophyll-a (Chl-a in different seasons. Surprisingly, the model revealed a weak N limitation (TSIN-TSIP = -10 corresponded to peak values of Chl-a in summer-autumn season, which is probably because the phytoplankton community is co-limited by N & P during the period. The shift of nutrition limitation during winter-spring would partially explain high values of Chl-a throughout 1996. This study suggests that seasonal patterns of nutrient limitation must be considered to develop effective management measures to control cyanobacterial blooms.

Karina Emanuella Peixoto de Souza GOMES

Full Text Available ABSTRACT Objective To evaluate the association between food consumption patterns and obesity in preschool children in Feira de Santana, Bahia, Brazil. Methods Cross-sectional, population-based nested within a live-birth cohort study of 813 children, which has started in 2004 in Feira de Santana, Bahia. The anthropometric status among children under four years of age was evaluated based on their body mass index; obesity/severe obesity was defined as a Z-score >+2. The Food Frequency Questionnaire was used to identify dietary patterns using principal components analysis. The association between obesity and food consumption patterns was assessed using Pearson’s Chi-squared test and logistic regression, adopting p<0.05 to denote statistical significance. Results Obesity was detected in 12.7% of the children investigated. Four food consumption patterns were identified: dietary pattern 1 (milk and other dairy products, vegetables and tubers, cereals, legumes, fruits, and fish; dietary pattern 2 (deep-fried or baked snacks, soft drinks/artificial fruit juices, oils and fats, sweets, and coffee/tea; dietary pattern 3 (encased meats, fast food, ketchup/mayonnaise, and eggs; and, dietary pattern 4 (chicken and red meats. Obesity was statistically associated with high adherence to the dietary pattern 3 (OR=1.92; 95%CI=1.01-3.66. Conclusion The results obtained showed that the high intake of energy-dense foods (dietary pattern 3 was a contributing factor to childhood obesity. These data reinforce the need for public policies and food education programs in health units and schools, aiming to change children’s eating habits, significant predictors of nutritional problems.

Regular nut consumption is associated with reduced risk factors for chronic disease; however, most population-based studies lack consideration of effect modification by dietary pattern. The UK Women's Cohort Study (UKWCS) provides an ideal opportunity to examine relationships between nut consumption and chronic disease risk factors in a large sample with diverse dietary patterns. Nut and nutrient intake from 34,831 women was estimated using a food frequency questionnaire among self-identified omnivores, vegetarians and vegans. In this cross-sectional analysis, higher nut consumption was associated with lower body weight (difference between highest and lowest consumption categories from adjusted model: 6.1 kg; 95% CI: 4.7, 7.6) body mass index (BMI, 2.4 units difference; 95% CI: 1.9, 2.9), and waist circumference (2.6 cm difference; 95% CI: 1.4, 3.8) (all p for linear trend vegans. Findings support existing literature around beneficial effects of nut consumption and suggest that benefits may be larger among omnivores. Nut promotion strategies may have the highest population impact by specifically targeting this group.

Background: Mexico has experienced shifts in food availability and consumption patterns over the past few decades from traditional diets to those containing more high-energy density foods, resulting in the development of unhealthful dietary patterns among children and adults. However, to our knowledge it is not known whether breakfast consumption patterns contribute to the overall daily diet of Mexican children. Objective: We examined total-day diet among breakfast consumers compared with breakfast skippers, identified and investigated breakfast dietary patterns in relation to energy and nutrient intakes at breakfast and across the day, and examined these patterns in relation to sociodemographic characteristics. Methods: With the use of nationally representative dietary data (one 24-h recall) from the 2012 Mexican National Health and Nutrition Survey, 3760 children aged 4-13 y were categorized into mutually exclusive breakfast patterns with the use of cluster analysis. The association between breakfast patterns and breakfast skippers with dietary intake at breakfast and for the total day was investigated with the use of multivariate linear regression. Results: Most children (83%) consumed breakfast. Six breakfast dietary patterns were identified (milk and sweetened breads, tortillas and beans, sweetened beverages, sandwiches and quesadillas, eggs, and cereal and milk) and reflected both traditional and more Westernized dietary patterns. Sugar-sweetened beverages were consumed across all patterns. Compared with all breakfast dietary patterns, breakfast skippers had the lowest intake of several nutrients of public health concern. Nutrients to limit that were high at breakfast tended to be high for the total day and vice versa for nutrients to encourage. Conclusions: There was not a single pattern that complied perfectly with the Mexican School Breakfast Guidelines, but changes such as increasing dietary fiber by encouraging more whole grains, fruits, vegetables, and

The purpose of this study was to examine the association of 100% orange juice (OJ) consumption by children 2 to 18 years of age (n = 7250) participating in the 2003 to 2006 National Health and Nutrition Examination Survey with intakes of select nutrients, MyPyramid food groups, diet quality-measured by the Healthy Eating Index-2005, weight status, and associated risk factors. The National Cancer Institute method was used to estimate the usual intake of 100% OJ consumption, selected nutrients, and MyPyramid food groups. Percentages of the population below the Estimated Average Requirement were determined. Covariate adjusted logistic regression was used to determine if consumers had a lower odds ratio of being overweight or obese. Usual per capita intake of 100% OJ was 1.7 oz/d. Among consumers, the usual intake of 100% OJ for children (n = 2183; 26.2% of population) was 10.2 oz/d. Consumers had higher (P juice, and whole fruit. Moderate consumption of 100% OJ should be encouraged in children as a component of a healthy diet. Copyright © 2011 Elsevier Inc. All rights reserved.

This study presents an integrated k-means clustering and gravity model (IKCGM) for investigating the spatiotemporal patterns of nutrient and associated dissolved oxygen levels in Tampa Bay, Florida. By using a k-means clustering analysis to first partition the nutrient data into a user-specified number of subsets, it is possible to discover the spatiotemporal patterns of nutrient distribution in the bay and capture the inherent linkages of hydrodynamic and biogeochemical features. Such patterns may then be combined with a gravity model to link the nutrient source contribution from each coastal watershed to the generated clusters in the bay to aid in the source proportion analysis for environmental management. The clustering analysis was carried out based on 1 year (2008) water quality data composed of 55 sample stations throughout Tampa Bay collected by the Environmental Protection Commission of Hillsborough County. In addition, hydrological and river water quality data of the same year were acquired from the United States Geological Survey's National Water Information System to support the gravity modeling analysis. The results show that the k-means model with 8 clusters is the optimal choice, in which cluster 2 at Lower Tampa Bay had the minimum values of total nitrogen (TN) concentrations, chlorophyll a (Chl-a) concentrations, and ocean color values in every season as well as the minimum concentration of total phosphorus (TP) in three consecutive seasons in 2008. The datasets indicate that Lower Tampa Bay is an area with limited nutrient input throughout the year. Cluster 5, located in Middle Tampa Bay, displayed elevated TN concentrations, ocean color values, and Chl-a concentrations, suggesting that high values of colored dissolved organic matter are linked with some nutrient sources. The data presented by the gravity modeling analysis indicate that the Alafia River Basin is the major contributor of nutrients in terms of both TP and TN values in all seasons

Full Text Available BACKGROUND: Alcoholic beverages are widely available in the university environment, particularly at the parties. There are few studies addressing the relationship between alcohol consumption and academic performance among college students. OBJECTIVE: This study evaluated the behavior of college students regarding the profile of alcohol consumption and its academic consequences. METHODS: The volunteers (343 students answered a questionnaire about their pattern of alcohol consumption and possible related behaviors, especially academic performance. Participants were classified as "non-drinkers" (ND, "non-binge drinkers" (nBD, "binge drinkers" (BD and "heavy drinkers" (HD. RESULTS: 88.1% of the students reported ingesting alcoholic beverages, 44% as BD. Most of the drinker students (75.5% - nBD, BD or HD stated getting intoxicated at least once a month. Binge drinking was the predominant pattern (66.2% of those who drank. HD students presented a risk 9.2 times higher of not being in the ideal period of the course. DISCUSSION: The college students evaluated presented high rates of alcohol abuse. Binge drinking might have interfered in their academic performance. Organic, social and behavioral consequences were also reported.

A Cold Core Eddy (CCE) mediated nutrient pattern in the North Eastern Arabian Sea (NEAS) is explained based on in situ measurments during March 2013 onboard FORV Sagar Sampada which was not reported earlier in the area. Samples for physical, chemical and biological parameters were collected in 5 stations along the diameter of the eddy and following standard protocols. The core of the CCE is identified at 21°20.38'N; 66°30.68'E with a diameter of 120Km. Earlier studies explaining the process and the forcing mechanism of the particular eddy records that, the eddy is short term (1-3 months) and is regular during the season. Surface waters were well oxygenated (>4.8 ml L-1) in the core. Surface value of nutrients viz., Nitrate, Nitrite, Silicate and phosphate in the core regions was 0.9µM, 0.01 µM, 0.5 µM and 0.7 µM respectively indicating upwelling in the core. Spring intermonsoon (SIM) is generally termed as a transition period between the active winter and summer seasons and as per earlier studies, high biological production and the regularly occurring Noctilica bloom is supported by the nutrient loading due to convective mixing during winter as well as regenerated production. However, present observations shows that, nutrient pumping due to the upwelling associated with the CCE also contributes for sustaining high biological production and are evident in the Chl a and mesozooplankton biovolume which records values of 4.35mg/m3 and 1.09ml/m3 respectively in the core. An intense Noctiluca blooms observed in the western flank of the eddy (Chl a 13.25 mg/m3; cell density 5.8×106 cells/litre), where Nitrate concentration records 1.04µM explains the role of such mesoscale processes in the sustenance of the HAB events. While eastern flank of the CCE showed typical open ocean condition of the season showing Nitrate 0.08µM; Chl a 0.23mg/m3; and phytoplankton cell density as 421 cells/litre.

[Changes in the patterns of food consumption in Latin America].

Science.gov (United States)

Tagle, M A

1988-09-01

Food consumption patterns have suffered important although not generalized changes in recent years. A series of factors favor these changes, such as variations in family income, rural-urban migration, increase of tertiary activities related to foods, and exposure to commercial propaganda. All of these factors, when compared among them, do not have the same impact or validity. Thus, while the first two induce changes in the food pattern, the last two guide the consumer to certain food products. Modernization of the food pattern in Latin America and the Caribbean has been inspired by the USA food pattern of the previous decade, which from the nutritional and economic points of view, does not prove to be desirable. The average USA diet is rich in both saturated and mono- and polyunsaturated fats, as well as in refined sugar and all types of additives. It is poor in carbohydrates, particular in those of the complex type; most of its protein is of animal origin. It may also be rich in salt and poor in fiber, as it is made up by well-diversified industrialized foods in their presentation, manufactured and marketed by a highly industrialized production-distribution capitalized structure. The adopted model is not in correspondence with out countries' natural resources; it produces a displacement of the consumption patterns based on autochthonous and/or traditional components, and induces an increase in food imports. Since Latin American countries are of poor economic resources, and the model renders expensive products, these are absorbed by the socioeconomic group able to pay for them and/or--intermittently--as a high-cost product by calorie delivered, by the poor groups who are most in need, a situation which would imply serious damage on the quality and quantity of their diet. Changes in food habits and in food consumption patterns are related to a certain socio-demographic process which cannot be stopped. Consequently, this process should be carefully analyzed and

Nutrition is critically important in the first 1000 days, and while most American babies are fed commercial baby foods, there is little or no evidence from nationally representative data to understand the implications of such consumption. We used 24-hour dietary recall data for 505 infants from The Feeding Infants and Toddlers Study to describe food consumption patterns and micronutrient density of complementary foods consumed by infants fed commercially prepared baby food fruit, vegetables, and dinners and compared with those eaten by nonconsumers of these products. Results show that consumers were significantly more likely to report eating all vegetables (excluding white potatoes, 71% vs 51%), deep yellow vegetables (42% vs 18%), and fruits (79% vs 65%) and were less likely to report eating white potatoes (10% vs 24%), dark green vegetables (4% vs 20%), and sweets (23% vs 47%) than were nonconsumers. Nutrient density of the complementary foods of consumers was greater for fiber, potassium, vitamin A, vitamin C, vitamin E, and magnesium, but lower in sodium and vitamin D. We conclude that infants fed commercially prepared baby foods were more likely to eat vegetables and fruits, and their diets were higher in several micronutrients. These findings provide important insights on complementary feeding and are useful to support the development of evidence-based infant-feeding guidelines.

Proliferative response of the murine esophageal epithelium to radiation: Modification by food consumption patterns

International Nuclear Information System (INIS)

Burholt, D.R.

1985-01-01

The single layer of proliferative epithelial cells of the murine esophagus undergoes a sequence of damage and recovery following cytotoxic insult. The modification of both damage and proliferative recovery by the alteration of animal eating patterns was investigated following thoracic field irradiation through the determination of /sup 3/H-TdR incorporation into the esophagus along with selective counting of labeled nuclei and mitotic figures. Initial radiation-induced damage, as determined by /sup 3/H-TdR incorporation suppression and mitotic delay, is under normal conditions dependent on the time of day of treatment. This circadian sensitivity may be altered by changing the eating pattern of the animal. The proliferative recovery following single dose irradiation is also dependent on food consumption patterns: fasting immediately following treatment and then refeeding 2 days later results in a more rapid proliferative recovery than observed under control eating conditions, while reduced food consumption during the period of proliferative hyperplasia reduces the extent of recovery. During multifraction radiation schedules both the damage produced by a subsequent dose and recovery capacity are influenced by the food consumption pattern between fractions

History of yogurt and current patterns of consumption.

Science.gov (United States)

Fisberg, Mauro; Machado, Rachel

2015-08-01

Yogurt has been a part of the human diet for several millennia and goes by many names throughout the world. The word "yogurt" is believed to have come from the Turkish word "yoğurmak," which means to thicken, coagulate, or curdle. While references to the health-promoting properties of yogurt date back to 6000 BC in Indian Ayurvedic scripts, it was not until the 20th century that Stamen Grigorov, a Bulgarian medical student, attributed the benefits to lactic acid bacteria. Today, most yogurt is fermented milk that is acidified with viable and well-defined bacteria (Lactobacillus bulgaricus and Streptococcus thermophiles). While patterns of yogurt consumption vary greatly from country to country, consumption is generally low. In the United States and Brazil, for example, only 6% of the population consume yogurt on a daily basis. Low consumption of yogurt represents a missed opportunity to contribute to a healthy lifestyle, as yogurt provides a good to excellent source of highly bioavailable protein and an excellent source of calcium as well as a source of probiotics that may provide a range of health benefits. © The Author(s) 2015.

Nutrient timing revisited: is there a post-exercise anabolic window?

OpenAIRE

Aragon Alan Albert; Schoenfeld Brad Jon

2013-01-01

Abstract Nutrient timing is a popular nutritional strategy that involves the consumption of combinations of nutrients--primarily protein and carbohydrate--in and around an exercise session. Some have claimed that this approach can produce dramatic improvements in body composition. It has even been postulated that the timing of nutritional consumption may be more important than the absolute daily intake of nutrients. The post-exercise period is widely considered the most critical part of nutri...

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.

Energy drinks are youth-targeted beverages that contain high amounts of caffeine and other stimulants. A number of deleterious health effects associated with consumption of these drinks have already been reported. Despite the health concerns, energy drinks research has been sparse, especially at younger ages. The main purpose of this study was to determine the prevalence of energy drinks consumption and patterns of use among adolescents. Cross-sectional study of students aged between 11 - 17 years-old attending four public schools in Braga, cluster sampled. A self-administrated questionnaire was used to access sociodemographic data, self-reported academic performance as well as energy drinks consumption patterns, attitudes, awareness and associated symptoms. In a total of 1414 adolescents studied (mean age 15.1 ± 1.5 years; 53.9% were females), 56.7% reported to have used energy drinks at least once (62.5% in males; 52.1% in females). Of those, 34% described a regular consumption (at least once a month) and 14.1% a weekly consumption. The most common reasons for energy drinks consumption were the pleasant taste (49%), desire to increase global energy (35%) or sports performance (33%). On average, energy drinks users were older compared with non-users. Energy drinks consumption was associated with male gender and with self-reported worse academic performance. Approximately onethird experienced at least one symptom after consumption. In addition, 39.9% of energy drinks consumers reported mixing those with alcohol. Consumption of energy drinks has been increasing. The prevalence found for its consumption in this study is similar to that reported in the literature. Knowledge about motivation, general awareness of the risks or other variables related to consumption of these drinks might allow a better characterization of this behavior. This study showed a high prevalence of energy drinks consumption among adolescents from a city in Northern Portugal

Nutrients, foods, and colorectal cancer prevention.

Diet has an important role in the development of colorectal cancer. In the past few decades, findings from extensive epidemiologic and experimental investigations have linked consumption of several foods and nutrients to the risk of colorectal neoplasia. Calcium, fiber, milk, and whole grains have been associated with a lower risk of colorectal cancer, and red meat and processed meat have been associated with an increased risk. There is substantial evidence for the potential chemopreventive effects of vitamin D, folate, fruits, and vegetables. Nutrients and foods also may interact, as a dietary pattern, to influence colorectal cancer risk. Diet likely influences colorectal carcinogenesis through several interacting mechanisms. These include the direct effects on immune responsiveness and inflammation, and the indirect effects of overnutrition and obesity-risk factors for colorectal cancer. Emerging evidence also implicates the gut microbiota as an important effector in the relationship between diet and cancer. Dietary modification therefore has the promise of reducing colorectal cancer incidence. Copyright © 2015 AGA Institute. Published by Elsevier Inc. All rights reserved.

Replacing typical American snacks with tree nuts may be an effective way to improve diet quality and compliance with the 2015-2020 Dietary Guidelines for Americans (DGAs). To assess and quantify the impact of replacing typical snacks with composite tree nuts or almonds on diet metrics, including empty calories (i.e., added sugars and solid fats), individual fatty acids, macronutrients, nutrients of public health concern, including sodium, fiber and potassium, and summary measures of diet quality. Food pattern modeling was implemented in the nationally representative 2009-2012 National Health and Examination Survey (NHANES) in a population of 17,444 children and adults. All between-meal snacks, excluding beverages, were replaced on a per calorie basis with a weighted tree nut composite, reflecting consumption patterns in the population. Model 1 replaced all snacks with tree nuts, while Model 2 exempted whole fruits, non-starchy vegetables, and whole grains (>50% of total grain content). Additional analyses were conducted using almonds only. Outcomes of interest were empty calories (i.e., solid fats and added sugars), saturated and mono- and polyunsaturated fatty acids, fiber, protein, sodium, potassium and magnesium. The Healthy Eating Index-2010, which measures adherence to the 2010 Dietary Guidelines for Americans, was used as a summary measure of diet quality. Compared to observed diets, modeled food patterns were significantly lower in empty calories (-20.1% and -18.7% in Model 1 and Model 2, respectively), added sugars (-17.8% and -16.9%), solid fats (-21.0% and -19.3%), saturated fat (-6.6% and -7.1%)., and sodium (-12.3% and -11.2%). Modeled patterns were higher in oils (65.3% and 55.2%), monounsaturated (35.4% and 26.9%) and polyunsaturated fats (42.0% and 35.7%), plant omega 3 s (53.1% and 44.7%), dietary fiber (11.1% and 14.8%), and magnesium (29.9% and 27.0%), and were modestly higher in potassium (1.5% and 2.9%).

2011-01-01

This paper addresses the topic of energy and development through a multi-disciplinary and systemic approach that combines environmental considerations with a social understanding of consumption. The focus is on electricity usage in the home and specifically lighting and cooling. Set in the urban mega-polis of Metro Manila, the Philippines, energy consumption is first placed in its biophysical perspective: the energy sources and electricity grid are presented, in relation to the Philippines as well as the region. The research findings then explore the social and cultural drivers behind household electricity consumption, revealing in several examples the strong influence of globalization-understood here as the flow of people, remittances, images and ideas. Policy recommendations are provided, based on the research results, with concluding remarks relevant to other similar contexts. - Research highlights: →Metro Manila household electricity consumption is environmentally significant. →The meaning given to electricity services varies by socio-economic group. →Structural conditions, such as building type, can lock-in energy consumption. →Global flows-people, ideas, remittances-influence local consumption patterns. →Social networks, rather than the individual consumer, can influence change.

Food pictures are suitable visual tools for quantize food and nutrient consumption avoiding bias due to self-assessments. To determine the perception of food portion size and to establish the efficacy of food pictures for dietaries assessments. A food frequency questionnaire (FFQ) including 118 food items of daily consumption was applied to 30 adults representative of Córdoba, Argentina, population. Among several food models (paper maché, plastics) and pictures, those which more accurately filled the purpose were selected. 3 small, median and large standard portion size were determined. Data were evaluated with descriptive statistics tools and Chi square adherence test. The assessment of 51 percent of the food was assayed in concordance with the reference size. In general, the remainder was overestimated. The 90 percent of volunteers concluded that the pictures were the best visual resource. The photographic atlas of food is an useful material for quantize the dietary consumption, suitable for many types of dietaries assessments. In conclusion, comparison among pictures of three portions previously standardized for each food is highly recommendable.

Yogurt consumption has been associated with higher nutrient intakes, better diet quality and improved metabolic profiles in adults. Few studies have investigated these associations in children. This study investigated the association of yogurt consumption with nutrient intakes, diet quality and metabolic profile in British children. Data from  1687 children aged 4-10 and 11-18 years of the National Diet and Nutrition Survey (NDNS) years 1-4 were analysed. Yogurt consumption was determined using a 4-day diet diary. Diet quality was assessed by the Healthy Eating Index 2010 (HEI-2010). Anthropometric measures, blood pressure, pulse pressure, plasma glucose, HbA1c, C-reactive protein, triacylglycerol, total cholesterol, high-and low-density cholesterol from NDNS were used. The highest tertile of yogurt consumption (T3) was associated with higher nutrient intakes, particularly for calcium (children 4-10 years: P consumption was associated with significantly lower pulse pressure in children aged 4-10 years and lower HbA1c concentration, being shorter and having a larger hip circumference in children aged 11-18 years, compared with non-yogurt consumers. This study suggests that British children who are yogurt consumers (> 60 g/day) have higher overall diet quality, nutrient intakes and adequacy, lower pulse pressure (children aged 4-10 years) and HbA1c concentrations (children aged 11-18 years), were shorter and had a smaller hip circumference (children aged 11-18 years).

Principal component analysis (PCA) is a widely used exploratory method in epidemiology to derive dietary patterns from habitual diet. Such dietary patterns seem to originate from intakes on multiple days and eating occasions. Therefore, analyzing food intake of study populations with different levels of food consumption can provide additional insights as to how habitual dietary patterns are formed. We analyzed the food intake data of German adults in terms of the relations among food groups from three 24-h dietary recalls (24hDRs) on the habitual, single-day, and main-meal levels, and investigated the contribution of each level to the formation of PCA-derived habitual dietary patterns. Three 24hDRs were collected in 2010-2012 from 816 adults for an European Prospective Investigation into Cancer and Nutrition (EPIC)-Potsdam subcohort study. We identified PCA-derived habitual dietary patterns and compared cross-sectional food consumption data in terms of correlation (Spearman), consistency (intraclass correlation coefficient), and frequency of consumption across all days and main meals. Contribution to the formation of the dietary patterns was obtained through Spearman correlation of the dietary pattern scores. Among the meals, breakfast appeared to be the most consistent eating occasion within individuals. Dinner showed the strongest correlations with "Prudent" (Spearman correlation = 0.60), "Western" (Spearman correlation = 0.59), and "Traditional" (Spearman correlation = 0.60) dietary patterns identified on the habitual level, and lunch showed the strongest correlations with the "Cereals and legumes" (Spearman correlation = 0.60) habitual dietary pattern. Higher meal consistency was related to lower contributions to the formation of PCA-derived habitual dietary patterns. Absolute amounts of food consumption did not strongly conform to the habitual dietary patterns by meals, suggesting that these patterns are formed by complex combinations of variable food

A mathematical model is presented, which addresses individual hygiene practices during food preparation and consumption patterns in private homes. Further, the model links food preparers and consumers based on their relationship to household types. For different age and gender groups, the model...... was highest for young males (aged 18-29 years) and lowest for the elderly above 60 years of age. Children aged 0-4 years had a higher probability of ingesting a risk meal than children aged 5-17 years. This difference between age and gender groups was ascribed to the variations in the hygiene levels of food....... The simulated results show that the probability of ingesting a chicken risk meal at home does not only depend on the hygiene practices of the persons preparing the food, but also on the consumption patterns of consumers, and the relationship between people preparing and ingesting food. This finding supports...

Waterbirds can reallocate a considerable amount of nutrients within agricultural fields and between agriculture sites and wetlands. However their effects on biogeochemical cycles have rarely been quantified. We estimated bird numbers, diet (from stable isotope analysis), food supply, and the food consumption on rice fields by overwintering waterbirds in one of the most important areas for rice production in southwestern Europe and a key area for various migrating and resident waterbird species. Herein, we modelled the nutrient (N and P) recycling in rice fields, and their transport to reservoirs. The energy consumption by waterbirds (96,605 ± 18,311 individuals) on rice fields during winter averaged at 89.9 ± 39.0 kJ·m −2 , with its majority (89.9%) belonging to foraging on rice seeds. Thus, the birds removed about 26% of rice seeds leftover after harvest (estimated in 932.5 ± 504.7 seeds·m −2 in early winter) wherein common cranes and dabbling ducks (four species) were the most important consumers. Waterbirds foraging and roosting in the rice fields recycled more than 24.1 (1.0 kg·ha −1 ) of N and an additional 5.0 tons (0.2 kg·ha −1 ) of P in the Extremadura's rice fields during winter. Additionally, we estimated that 2.3 tons of N and 550 kg of P were removed from rice fields and transported to reservoirs. The seasonal foraging of wildlife should result in a direct benefit for rice farmers by improving nutrient recycling through defecation by waterbirds with respect to artificial fertilisation. Additionally, rice fields located in the cranes' core wintering areas can provide sufficient food supply to induce habitat shift from their traditional wintering habitat in ‘dehesas’ to rice fields, which causes indirect socioeconomic benefit through reduced acorn consumption by cranes. Our modelling approach may thus be especially helpful for management decisions regarding rice agroecosystems in areas which are also important for the

Mangrove forests are highly productive and play a major role in global carbon cycling. Their carbon accumulation can be influenced through the consumption of nutrient-poor leaves and propagules by herbivore crabs. Anthropogenic nutrient input from sewage contamination is widespread in these often naturally nutrient-limited ecosystems. We hypothesised that sewage-mediated nutrient input to mangrove stands of Paranaguá Bay (southern Brazil), would alter the nutrient sources available for crabs, e.g. through microphytobenthos increase, and that this would reflect in their feeding behaviour. We predicted that propagules of Rhizophora mangle in contaminated stands would experience lower grazing pressure from their two main local consumers (Ucides cordatus and Goniopsis cruentata). We compared herbivory rates on R. mangle propagules in sewage contaminated and uncontaminated mangrove stands. We found that herbivory rates were significantly lower in contaminated than uncontaminated forests, but this pattern could not be clearly attributed to increased nutrient availability.

Most fungi, including entomopathogenic fungi, have two different conidiation patterns, normal and microcycle conidiation, under different culture conditions, eg, in media containing different nutrients. However, the mechanisms underlying the conidiation pattern shift are poorly understood. In this study, Metarhizium acridum undergoing microcycle conidiation on sucrose yeast extract agar (SYA) medium shifted to normal conidiation when the medium was supplemented with sucrose, nitrate, or phosphate. By linking changes in nutrients with the conidiation pattern shift and transcriptional changes, we obtained conidiation pattern shift libraries by Solexa/Illumina deep-sequencing technology. A comparative analysis demonstrated that the expression of 137 genes was up-regulated during the shift to normal conidiation, while the expression of 436 genes was up-regulated at the microcycle conidiation stage. A comparison of subtractive libraries revealed that 83, 216, and 168 genes were related to sucrose-induced, nitrate-induced, and phosphate-induced conidiation pattern shifts, respectively. The expression of 217 genes whose expression was specific to microcycle conidiation was further analyzed by the gene expression profiling via multigene concatemers method using mRNA isolated from M. acridum grown on SYA and the four normal conidiation media. The expression of 142 genes was confirmed to be up-regulated on standard SYA medium. Of these 142 genes, 101 encode hypothetical proteins or proteins of unknown function, and only 41 genes encode proteins with putative functions. Of these 41 genes, 18 are related to cell growth, 10 are related to cell proliferation, three are related to the cell cycle, three are related to cell differentiation, two are related to cell wall synthesis, two are related to cell division, and seven have other functions. These results indicate that the conidiation pattern shift in M. acridum mainly results from changes in cell growth and proliferation. The

None of the studies of whole grains that have looked either at diet or weight/adiposity measures have focused exclusively on oatmeal. The objective of this study was to assess the association between oatmeal consumption and nutrient intake, diet quality, and weight/adiposity of children aged 2-18. A nationally representative sample of children aged 2-18 (N=14,690) participating in National Health and Nutrition Examination Survey 2001-2010 was used. Intake was determined from a single 24-h dietary recall. Diet quality was measured using the Healthy Eating Index-2010 (HEI-2010). Covariate-adjusted regression analyses, using appropriate sample weights, were used to determine differences between oatmeal consumers and non-consumers for demographics, nutrient intakes, diet quality, and weight/adiposity measures (pempty calories. Children consuming oatmeal were at lower risk for having central adiposity and being obese. Consumption of oatmeal by children was associated with better nutrient intake, diet quality, and reduced risk for central adiposity and obesity and should be encouraged as part of an overall healthful diet.

Crack cocaine use is associated with polydrug abuse, and inpatients dependent on crack exhibit profiles of serious consumption patterns. Use of alcohol and tobacco and other drugs is a risk factor for experimentation of additional drugs, including crack cocaine. The present study describes the characteristics and crack consumption patterns among inpatients in treatment during 2011 and 2012 at the Hospital Psiquiátrico São Pedro (Porto Alegre, Brazil). An additional objective was to identify the sequence of alcohol and tobacco consumption prior to crack use. The participants were 53 male inpatients addicted to crack with a mean age of 27.5±7.3 years. A sociodemographic questionnaire; the Alcohol, Smoking and Substance Involvement Screening Test and the Mini Mental State Examination were all administered to participants. Inclusion criteria were crack cocaine dependency (based on the 10th edition of the International Classification of Diseases [ICD-10]) and being abstinent for 7 days. Patients with cognitive difficulties who were unable to understand and/or respond to the questionnaires were excluded from the sample. The participants were young male adults with low educational level and low incomes and were polydrug users. The majority had made more than one attempt to quit. Use of legal drugs in early adolescence, prior to crack use, was identified. The profiles of the inpatients addicted to crack treated at this hospital indicate a serious usage pattern among those who seek specialized support. Crack use is frequent and is associated with use of other drugs and with difficulty sustaining abstinence. The pattern of progression from alcohol and tobacco use to crack cocaine dependency demands the attention of those responsible for prevention policies.

Larch is the main timber species of forest plantations in North China. Imbalance in nutrient cycling in soil emerged due to single species composition and mono system structure of plantation. Thus it is necessary to grasp its biomass and nutrients allocation for scientific management and nutrient cycling studies of larch plantation. We measured aboveground biomass (stem, branch, bark and leaf) and nutrient concentrations (C, N, P, K, Ca, Mg, Fe, Mn, Cu and Zn), and analyzed the patterns of accumulation and distribution of 19-year-old larch plantation with diameter at breast height of 12. 8 cm, tree height of 15. 3 m, and density of 2308 trees · hm(-2), in a montane region of eastern Liaoning Province, China. The results showed that aboveground biomass values were 70.26 kg and 162.16 t · hm(-2) for the individual tree of larch and the stand, respectively. There was a significant difference between biomass of the organs, and decreased in the order of stem > branch > bark > leaf. Nutrient accumulation was 749.94 g and 1730.86 kg · hm(-2) for the individual tree of larch and the stand, respectively. Nutrient accumulation of stem was significantly higher than that of branch, bark and leaf, whether it was macro-nutrient or micro-nutrient. Averagely, 749.94 g nutrient elements would be removed from the system when a 19-year-old larch tree was harvested. If only the stem part was removed from the system, the removal of nutrient elements could be reduced by 40.7%.

Unrecorded homemade alcohol consumption has been less examined in the literature. Previous studies of homemade alcohol in Russia have almost entirely focused upon the use of samogon (moonshine) attributed to the northern style of drinking. No systematic analysis is available regarding the production and consumption of homemade wine. This paper explores the drinking patterns demonstrated by consumers of samogon and homemade wine in Russia. The main factors affecting the consumption of these beverages are investigated. Data were collected from a 2014 nationwide survey of 14,986 respondents aged 15+ years. Beverage preferences, volume of consumed alcohol, drinking habits, and alcohol availability were the main measures reported. Demographic, socio-economic, spatial, and policy-related factors affecting homemade alcohol consumption are examined using logistic regression. The percentages of samogon and homemade wine consumers were similar, although a greater volume of samogon in pure alcohol was consumed compared to homemade wine. The groups of samogon and homemade wine consumers showed very little overlap. Unlike homemade wine consumers, samogon drinkers consumed larger amounts of alcohol and were more engaged in frequent and excessive drinking, drinking without meals and drinking in marginal public settings. Gender, education, regional affiliation, and type of residence showed opposite associations with regard to the consumption of samogon and homemade wine. Availability of homemade alcohol in the neighbourhood was the most influential predictor due to respondents' own production, presence of homemade alcohol in friendship networks and at illegal market. The prices of manufactured alcohol and the consumption of homemade alcohol did not show significant relationships. Consumers of samogon and homemade wine demonstrate contrasting drinking patterns that are largely driven by different factors. Samogon is consumed in a more hazardous manner, whereas homemade wine is

This study examines the extent to which a plant-based dietary intervention that discourages consumption of dairy products and meat influences bone-relevant nutrients. A randomized controlled study design was used to evaluate the Coronary Health Improvement Project. The Project is a heart disease prevention intervention administered in an intensive 40-hour educational course delivered over a 4-week period. Participants were evaluated at baseline, 6 weeks, and 6 months. After 6 weeks, participants in the intervention group compared with the control group experienced significant increases in magnesium and daily intake of fruit, vegetables, and grains but significant decreases in dairy servings per day and calcium and vitamin D from food. After 6 months, those in the intervention group showed significant increases in daily intake of fruit, vegetables, and grains and significant decreases in dairy servings per day, daily meat consumption, and protein, phosphorous, calcium, total calcium, and vitamin D from food. Serum calcium levels are the primary determinant of parathyroid hormone (PTH) release, and within 6 weeks, the intervention group's PTH levels were elevated from baseline and significantly different from the control group's PTH levels. At 6 months, urinary type I collagen N-telopeptide (NTx) levels were significantly greater in the intervention group compared with the control group. The Coronary Health Improvement Project increases the intake of important food items but decreases calcium and vitamin D consumption. There is also some evidence of an increase in NTx biomarkers, consistent with increased bone resorption.

To examine the effect of fast-food and full-service restaurant consumption on total energy intake, dietary indicators, and beverage consumption. Individual-level fixed-effects estimation based on 2 nonconsecutive 24-hour dietary recalls. Nationally representative data from the 2003-2004, 2005-2006, and 2007-2008 National Health and Nutrition Examination Survey. Children aged 2 to 11 years (n = 4717) and adolescents aged 12 to 19 years (n = 4699). Daily total energy intake in kilocalories; intake of grams of sugar, total fat, saturated fat, and protein and milligrams of sodium; and total grams of sugar-sweetened beverages, regular soda, and milk consumed. Fast-food and full-service restaurant consumption, respectively, was associated with a net increase in daily total energy intake of 126.29 kcal and 160.49 kcal for children and 309.53 kcal and 267.30 kcal for adolescents and with higher intake of regular soda (73.77 g and 88.28 g for children and 163.67 g and 107.25 g for adolescents) and sugar-sweetened beverages generally. Fast-food consumption increased intake of total fat (7.03-14.36 g), saturated fat (1.99-4.64 g), and sugar (5.71-16.24 g) for both age groups and sodium (396.28 mg) and protein (7.94 g) for adolescents. Full-service restaurant consumption was associated with increases in all nutrients examined. Additional key findings were (1) adverse effects on diet were larger for lower-income children and adolescents and (2) among adolescents, increased soda intake was twice as large when fast food was consumed away from home than at home. Fast-food and full-service restaurant consumption is associated with higher net total energy intake and poorer diet quality.

The rise of nutrition-related diseases in developed countries prompts investigation into the role played by changing food patterns. Our aim was to observe changes in food-at-home purchases by French households and their impacts on nutritional quality over the past 40 years (1969-2010). Time-series of food-at-home purchases from representative samples of French households were built based on two sources of data: the INSEE National Food Survey (1969-1991) and the Kantar Food Consumption Panel (1989-2010). Food-at-home purchases were converted into energy and nutrients using the French CIQUAL food composition table. The nutritional quality of food-at-home purchases was estimated using the mean adequacy ratio (MAR) for 15 key nutrients. MAR was expressed per 2000 kcal to assess the nutrient density of food-at-home purchases. Between 1969 and 2010, food-at-home purchases showed dramatic changes in many food groups, with increasing processed vs raw products. The purchase of calories increased (+6.7%) and nutrient density improved (MAR per 2000 kcal + 12.9 points). However, this overall trend harbors heterogeneous patterns: food-at-home calories decreased and nutrient density improved up to 2002, but then calories increased while nutrient density stabilized. The nutritional quality of French households' food-at-home purchases improved over the last 40 years, as shown by increasing nutrient density. However, during the last decade, nutrient density ceased to increase and the purchase of calories increased, advocating a need for public action to promote healthier food purchasing patterns.

People with low income tend to eat less balanced than people with higher income. This seems to be particularly the case for people with migration background. This cross-sectional study examined the relation of consumption patterns of 597 food bank users with different migration background in Germany. Questionnaires were distributed assessing sociodemographic information and consumption patterns. Analyses were conducted using binary logistic regressions. Models were controlled for age, gender, type of household and education. The group of German food bank users consumed fewer fruits and vegetables and less fish compared to all other groups with migration background (former USSR, Balkan region, Middle East). A significant predictor for fruit and vegetable consumption was migration status. Participants from the former USSR consumed less often SSBs compared to the other groups. Dietary recommendations for low income populations should take into consideration other aspects besides income such as migration status.

Excessive use of firewood, as a primary source of energy for domestic purposes, is leading to severe deforestation in the northeastern Himalayan region. Firewood consumption pattern of three tribal communities of Meghalaya, India- Garo, Khasi and Jaintia was studied under varying ecological, socio-economic and socio-cultural conditions. Fuelwood consumption was highest to Khasi community (5.81 kg/capita/day), followed by the Garo (5.32 kg/capita/day) and Jaintia (3.90 kg/capita/day), respectively, irrespective of their socio-economic status. The labour energy expenditure for fuelwood collection was highest for the Jaintia (88.56 MJ/capita/yr) and minimum to Garo (70.64 MJ/capita/yr). The fuelwood is burnt for various activities such as cooking, water heating, space heating, lighting and livestock rearing, etc. Among various activities, cooking required maximum energy. Commercial fuel is beyond the reach of the tribal communities due to their poor socio-economic conditions. The estimated growing stock is unable to sustain the rate of fuel consumption. This information could be utilized for developing appropriate technology for afforestation programmes in this region since 90% of the total population use biomass as an important source of energy

Seed selection by dark-eyed juncos (Junco hyemalis): optimal foraging with nutrient constraints?

Science.gov (United States)

Thompson, D B; Tomback, D F; Cunningham, M A; Baker, M C

1987-11-01

Observations of the foraging behavior of six captive dark-eyed juncos (Junco hyemalis) are used to test the assumptions and predictions of optimal diet choice models (Pyke et al. 1977) that include nutrients (Pulliam 1975). The birds sequentially encountered single seeds of niger thistle (Guizotia abyssinica) and of canary grass (Phalaris canariensis) on an artificial substrate in the laboratory. Niger thistle seeds were preferred by all birds although their profitability in terms of energy intake (J/s) was less than the profitability of canary grass seeds. Of four nutritional components used to calculate profitabilities (mg/s) lipid content was the only characteristic that could explain the junco's seed preference. As predicted by optimal diet theory the probability of consuming niger thistle seeds was independent of seed abundance. However, the consumption of 71-84% rather than 100% of the seeds encountered is not consistent with the prediction of all-or-nothing selection. Canary grass seeds were consumed at a constant rate (no./s) independent of the number of seeds encountered. This consumption pattern invalidates a model that assumes strict maximization. However, it is consistent with the assumption that canary grass seeds contain a nutrient which is required in minimum amounts to meet physiological demands (Pulliam 1975). These experiments emphasize the importance of incorporating nutrients into optimal foraging models and of combining seed preference studies with studies of the metabolic requirements of consumers.

Associations between Nut Consumption and Health Vary between Omnivores, Vegetarians, and Vegans

Full Text Available Regular nut consumption is associated with reduced risk factors for chronic disease; however, most population-based studies lack consideration of effect modification by dietary pattern. The UK Women’s Cohort Study (UKWCS provides an ideal opportunity to examine relationships between nut consumption and chronic disease risk factors in a large sample with diverse dietary patterns. Nut and nutrient intake from 34,831 women was estimated using a food frequency questionnaire among self-identified omnivores, vegetarians and vegans. In this cross-sectional analysis, higher nut consumption was associated with lower body weight (difference between highest and lowest consumption categories from adjusted model: 6.1 kg; 95% CI: 4.7, 7.6 body mass index (BMI, 2.4 units difference; 95% CI: 1.9, 2.9, and waist circumference (2.6 cm difference; 95% CI: 1.4, 3.8 (all p for linear trend < 0.001. Higher nut consumption was also associated with reduced prevalence of high cholesterol and high blood pressure; having a history of heart attack, diabetes and gallstones; and markers of diet quality (all adjusted p for linear trend ≤ 0.011. Higher nut consumption appeared overall to be associated with greater benefits amongst omnivores compared to vegetarians and vegans. Findings support existing literature around beneficial effects of nut consumption and suggest that benefits may be larger among omnivores. Nut promotion strategies may have the highest population impact by specifically targeting this group.

This paper explores how China’s household consumption patterns over the period 2005–2050 influence the total energy demand and carbon dioxide (CO 2 ) emissions in two baseline scenarios, and how it influences carbon prices as well as the economic cost in the corresponding carbon mitigation scenarios. To this end we first put forward two possible household consumption expenditure patterns up to 2050 using the Working–Leser model, taking into account total expenditure increase and urbanization. For comparison, both expenditure patterns are then incorporated in a hybrid recursive dynamic computable general equilibrium model. The results reveal that as income level increases in the coming decades, the direct and indirect household energy requirements and CO 2 emissions would rise drastically. When household expenditure shifts from material products and transport to service-oriented goods, around 21,000 mtce of primary energy and 45 billion tons of CO 2 emissions would be saved over the 45-year period from 2005 to 2050. Moreover, carbon prices in the dematerialized mitigation scenario would fall by 13% in 2050, thus reducing the economic cost. - Highlights: ► Propose two household expenditure patterns considering income rise and urbanization. ► Much energy and CO 2 emissions would be saved in low-carbon consumption scenario. ► Carbon prices would reduce a lot in low-carbon consumption scenario.

Several instruments developed to assess dietary intake of groups or populations have strengths and weaknesses that affect their specific application. No self-administered, closed-ended dietary survey was previously used in Argentina to assess current food and nutrient intake on a daily basis. To design and validate a self-administered, structured food record (NutriQuid, NQ) representative of the adult Argentine population's food consumption pattern to measure individual energy and nutrient intake. Records were loaded onto a database using software that checks a regional nutrition information system (SARA program), automatically quantifying energy and nutrient intake. NQ validation included two phases: (1) NQ construct validity comparing records kept simultaneously by healthy volunteers (45-75 years) and a nutritionist who provided meals (reference), and (2) verification of whether NQ reflected target population consumption (calories and nutrients), week consumption differences, respondent acceptability, and ease of data entry/analysis. Data analysis included descriptive statistics, repeated measures ANOVA, intraclass correlation coefficient, nonparametric regression, and cross-classification into quintiles. The first validation (study group vs. reference) showed an underestimation (10%) of carbohydrate, fat, and energy intake. Second validation: 109 volunteers (91% response) completed the NQ for seven consecutive days. Record completion took about 9min/day, and data entry 3-6min. Mean calorie intake was 2240±119kcal/day (42% carbohydrates, 17% protein, and 41% fat). Intake significantly increased in the weekend. NQ is a simple and efficient tool to assess dietary intake in large samples. Copyright © 2018 SEEN y SED. Publicado por Elsevier España, S.L.U. All rights reserved.

Nutrient discharge into peri-urban streams and reservoirs constitutes a significant pressure on environmental management, but quantitative assessment of non-point source pollution under climate variability in fast changing peri-urban watersheds is challenging. Soil and Water Assessment Tool (SWAT) was used to simulate water budget and nutrient loads for landscape patterns representing a 30-year progression of urbanization in a peri-urban watershed near Tianjin metropolis, China. A suite of landscape pattern indices was related to nitrogen (N) and phosphorous (P) loads under dry and wet climate using CANOCO redundancy analysis. The calibrated SWAT model was adequate to simulate runoff and nutrient loads for this peri-urban watershed, with Nash-Sutcliffe coefficient (NSE) and coefficient of determination ( R 2) > 0.70 and percentage bias (PBIAS) between -7 and +18 for calibration and validation periods. With the progression of urbanization, forest remained the main "sink" landscape while cultivated and urban lands remained the main "source" landscapes with the role of orchard and grassland being uncertain and changing with time. Compared to 1984, the landscape use pattern in 2013 increased nutrient discharge by 10%. Nutrient loads modelled under wet climate were 3-4 times higher than that under dry climate for the same landscape pattern. Results indicate that climate change could impose a far greater impact on runoff and nutrient discharge in a peri-urban watershed than landscape pattern change.

Little is known about the dietary patterns and nutrient intakes of preschool children in Australia. A study was undertaken in Perth on Australian and migrant children to obtain information on preschool diets. It was found that, although the mean nutrient intakes in both groups were adequate, some individual migrant national groups showed deficiencies of one or more nutrients. Many children were obtaining excessive calories and protein. The consumption of "empty calorie" foods was also high. In order to find different ways to teach good principles and practice of nutrition, the types of media which might influence parents were studied. It was considered that television and, to a lesser degree, radio were media which might exert a considerable effect if they were used to the best advantage. These forms of communication particularly were of potential value, as some migrant parents could not read English and some were illiterate. A positive nutrition education programme to combat commerical food advertising of "empty calorie" foods is recommended.

Background None of the studies of whole grains that have looked either at diet or weight/adiposity measures have focused exclusively on oatmeal. Objective The objective of this study was to assess the association between oatmeal consumption and nutrient intake, diet quality, and weight/adiposity of children aged 2–18. Design A nationally representative sample of children aged 2–18 (N=14,690) participating in National Health and Nutrition Examination Survey 2001–2010 was used. Intake was determined from a single 24-h dietary recall. Diet quality was measured using the Healthy Eating Index-2010 (HEI-2010). Covariate-adjusted regression analyses, using appropriate sample weights, were used to determine differences between oatmeal consumers and non-consumers for demographics, nutrient intakes, diet quality, and weight/adiposity measures (pempty calories. Children consuming oatmeal were at lower risk for having central adiposity and being obese. Conclusions Consumption of oatmeal by children was associated with better nutrient intake, diet quality, and reduced risk for central adiposity and obesity and should be encouraged as part of an overall healthful diet.

Julie Hess

2014-10-01

Full Text Available The objective of this review was to identify dietary insufficiencies and excesses in children aged two to 11 in the United States (U.S. and eating habits that merit concern in terms of nutrient and energy density to improve overall diet quality. Data from the What We Eat in America (WWEIA tables from the National Health and Nutrition Examination Survey (NHANES were examined as well as survey data from the School Nutrition Dietary Assessment Study (SNDA. Analysis of survey data revealed that children consume insufficient Vitamin D, calcium, and potassium and excess energy, carbohydrates, and sodium. Dietary modifications are necessary to prevent serious deficiencies and the development of chronic illness. Snacking has steadily increased in this population since the 1970s, and snacks provide necessary nutrients. However, carbohydrates and added sugars tend to be over-consumed at snacking occasions. Replacement of current snack choices with nutrient-dense foods could lower the risks of nutrient deficiencies and help lower excess nutrient consumption. Increased consumption of low sugar dairy foods, especially yogurt, at snack times could increase intake of important micronutrients without contributing to dietary excesses.

Recovery of nutrient resources from the wastewater is now an inevitable strategy to maintain the supply of both nutrient and water for our huge population. While the intensive energy consumption in conventional nutrient recovery technologies still remained as the bottleneck towards the sustainable nutrient recycle. This study proposed an enlarged microbial nutrient recovery cell (EMNRC) which was powered by the energy contained in wastewater and achieved multi-cycle nutrient recovery incorporated with in situ wastewater treatment. With the optimal recovery solution of 3 g/L NaCl and the optimal volume ratio of wastewater to recovery solution of 10:1, >89% of phosphorus and >62% of ammonium nitrogen were recovered into struvite. An extremely low water input ratio of water. It was proved the EMNRC system was a promising technology which could utilize the chemical energy contained in wastewater itself and energy-neutrally recover nutrient during the continuous wastewater purification process.

In the study conducted the aim was to investigate strong personalities (SP) related to alcohol consumption in married students from Romania. Consisted in 2 samples: a case-sample (23 alcohol consumer students with a family pattern of weekly consumption, 47.8% male and 52.2% female, aged 21-29 years) and a control-sample (42 no-alcohol consumer students without a family pattern of consumption, 26.2% male and 73.8% female, aged 21-29 years), selected from a sample of 176 married students. An observational inquiry (case-control) consisted in applying 2 questionnaires: Health Questionnaire (60 items, 7: Q43-Q49 -alcohol consumption) and Strong Personalities Questionnaire (88 items, alpha-Crohnbach index-0.823). Statistical analysis was performed by the aid of SPSS 20 Program. For alcohol consumer students with weekly pattern of consumption the main reason of alcohol consumption was curiosity (60.9%) and the most frequent consumed alcohol was beer (38.6%, 500-3000 ml/week). Personalities' profiles revealed V-hyperthymic, III-hyperperseverant and X-emotive strong personalities (SP) as being symptomatic (over 50% symptomatic level-SL) for both samples, with a difference (control-case) for X-emotive SP (71.7% students--57.1% students, respectively). I-demonstrative, VII-cyclothymic and IV-unruly SP presented a difference between case (symptomatic: 61.8%; 61.8% and 61.8% students, respectively) and control (symptomatic: 36.8%; 37.5% and 45% students, respectively) samples. A statistically significant difference case-control samples was demonstrated for I-Demonstrative (item S29: chi square chi2 = 10.65; Sig.0.002; gamma correlation gamma=0.73; Sig.0.002) and for X-emotive (item S25: chi2 = 8.76; gamma = -0.66; Sig.0.003) SP. In conclusion, a relation SP-alcohol consumption in married students is suggested.

Cooking Banana Consumption Patterns in the Plantain-growing Area of Southeastern Nigeria

Directory of Open Access Journals (Sweden)

Tshiunza, M.

2001-01-01

Full Text Available Cooking bananas (Musa spp., ABB genome were intro-duced into Southeastern Nigeria by the International Institute of Tropical Agriculture (IITA in the mid-1980s as an interim measure to reduce the incidence of black sigatoka disease (caused by the fungus Mycosphaerel-la fijiensis Morelet on plantain. However, the people of this region were not familiar with their utilisation methods. To address this lack of the knowledge and thereby sustain cooking banana cultivation, IITA, in collaboration with the Shell Petroleum Development Company (SPDC and the Nigeria Agip OU Company (NAOC commenced a training campaign on cooking banana processing methods. This study examined the patterns of utilisation of cooking bananas ten years after the training took place and compared them with plantain. About 95 % of the households interviewed are consuming cooking banana, indicating a broad acceptance of the crop in the region. Overall, two ripening stages termed green and ripe are the most popular ripening stages for the consumption of both plantain and cooking banana, followed by partially ripe maturity stage. The most common forms of consumption for green plantain are, in decreasing order of importance, pottage, boiled, roasted, and fried. Green cooking banana is also mostly eaten in pottage and boiled forms, and less frequently in fried and pounded forms. Ripe plantain is mostly eaten in fried and pottage forms, while ripe cooking banana is mostly eaten in fried and raw forms. Partially ripe plantain is mostly eaten in pottage, fried, boiled, and roasted forms, while partially ripe cooking banana is eaten in fried, pottage and boiled forms. These results indicate that the consumption patterns of plantain and cooking banana are very similar. This similarity has greatly contributed to the rapid integration of cooking banana within the existing plantain consumption and cropping systems.

The relationship between dietary patterns and chronic disease is underexplored in indigenous populations. We assessed diets of 424 American Indian (AI) adults living in 5 rural AI communities. We identified four food patterns. Increased prevalence for cardiovascular disease was highly associated with the consumption of unhealthy snacks and high fat-food patterns (OR 3.6, CI=1.06, 12.3; and OR 6.0, CI=1.63, 22.1), respectively. Moreover, the food-consumption pattern appeared to be different by community setting (p<.05). We recommend culturally appropriate community-intervention programs to promote healthy behavior and to prevent diet-related chronic diseases in this high-risk population.

Healthy diet is an essential component in cancer survivorship care planning. Cancer survivors should be particularly prudent regarding their daily food choices, with an aim of ensuring safe consumption, reducing risk of recurrence or other comorbidity, and improving quality of life. We aimed to examine the impacts of fast-food and full-service restaurant consumption on daily energy and nutrient intakes among US adult cancer survivors. Nationally representative data of 1308 adult cancer survivors came from the National Health and Nutrition Examination Survey 2003-2012 waves. First-difference estimator was adopted to address confounding bias from time-invariant unobservables like personal food/beverage preferences by using within-individual variations in diet and restaurant consumption status between two non-consecutive 24-hour dietary recalls. Fast-food and full-service restaurant consumption, respectively, was associated with an increase in daily total energy intake by 125.97 and 152.26 kcal and sodium intake by 312.47 and 373.75 mg. Fast-food consumption was significantly associated with a decrease in daily vitamin A intake by 119.88 µg and vitamin K intake by 30.48 µg, whereas full-service restaurant consumption was associated with an increase in daily fat intake by 8.99 g and omega-6 fatty acid intake by 3.85 g, and a decrease in vitamin D intake by 0.93 µg. Compared with fast-food and full-service restaurant consumption at home, consumption away from home led to further reduced diet quality. Individualized nutrition counseling and food assistance programs should address cancer survivors' overall dining-out behavior rather than fast-food consumption alone. © The Author(s) 2015.

Full Text Available Abstract Background Given the epidemic of childhood obesity, it is crucial to assess food and beverage intake trends. Beverages can provide a large number of calories and since consumption patterns seem to develop at a young age we examined beverage consumption trends over three decades. The objective of this study was to assess the beverage (milk, fruit juice, fruit drinks, tea, soy beverages, and soft drinks consumption trends in children Methods Data from individuals ages Results During the NHANES 1976–1980 and 1988–1994 periods, approximately 84–85% of children were consuming milk, whereas only 77% were consuming milk during NHANES 2001–2006. Flavored milk intake was relatively low, but increased to 14% during the last decade (p  Conclusions Given concerns about childhood obesity and the need to meet nutrition requirements, it is prudent that parents, educators and child caretakers replace some of the nutrient poor beverages young children are currently consuming with more nutrient dense sources like low-fat and fat-free milk.

antimicrobials are reported at sales level without any information on the consumption by different animal species. This hinders a proper comparison of antimicrobial consumption at the species level between countries. However, it is imperative to improve our understanding on antimicrobial usage patterns...... consumption of different antimicrobial classes were also evident. Sulfonamides/trimethoprim and tetracyclines were consumed in a higher proportion in Switzerland than in Denmark, whereas the relative consumption of penicillins was higher in Denmark. The differences observed in veterinary antimicrobial...... consumption are not solely related to animal demographic characteristics in these two countries. Other factors, such as the level of biosecurity and farming practices, veterinarians and farmers’ education, or governmental/industry programs put in place might also partly explain these variations...

Avocado consumption is associated with better diet quality and nutrient intake, and lower metabolic syndrome risk in US adults: results from the National Health and Nutrition Examination Survey (NHANES) 2001-2008.

Avocados contain monounsaturated fatty acids (MUFA) dietary fiber, essential nutrients and phytochemicals. However, no epidemiologic data exist on their effects on diet quality, weight management and other metabolic disease risk factors. The objective of this research was to investigate the relationships between avocado consumption and overall diet quality, energy and nutrient intakes, physiological indicators of health, and risk of metabolic syndrome. Avocado consumption and nutrition data were based on 24-hour dietary recalls collected by trained NHANES interviewers using the USDA Automated Multiple Pass Method (AMPM). Physiological data were collected from physical examinations conducted in NHANES Mobile Examination Centers. Diet quality was calculated using the USDA's Healthy Eating Index-2005. Subjects included 17,567 US adults ≥ 19 years of age (49% female), including 347 avocado consumers (50% female), examined in NHANES 2001-2008. Least square means, standard errors, and ANOVA were determined using appropriate sample weights, with adjustments for age, gender, ethnicity, and other covariates depending on dependent variable of interest. Avocado consumers had significantly higher intakes of vegetables (pavocado consumers. The odds ratio for metabolic syndrome was 50% (95th CI: 0.32-0.72) lower in avocado consumers vs. non-consumers. Avocado consumption is associated with improved overall diet quality, nutrient intake, and reduced risk of metabolic syndrome. Dietitians should be aware of the beneficial associations between avocado intake, diet and health when making dietary recommendations.

This paper addresses the topic of energy and development through a multi-disciplinary and systemic approach that combines environmental considerations with a social understanding of consumption. The focus is on electricity usage in the home and specifically lighting and cooling. Set in the urban mega-polis of Metro Manila, the Philippines, energy consumption is first placed in its biophysical perspective: the energy sources and electricity grid are presented, in relation to the Philippines as well as the region. The research findings then explore the social and cultural drivers behind household electricity consumption, revealing in several examples the strong influence of globalization-understood here as the flow of people, remittances, images and ideas. Policy recommendations are provided, based on the research results, with concluding remarks relevant to other similar contexts. - Research highlights: {yields}Metro Manila household electricity consumption is environmentally significant. {yields}The meaning given to electricity services varies by socio-economic group. {yields}Structural conditions, such as building type, can lock-in energy consumption. {yields}Global flows-people, ideas, remittances-influence local consumption patterns. {yields}Social networks, rather than the individual consumer, can influence change.

The duration and pattern of breastfeeding can influence the consumption of fruits and vegetables in later childhood. To investigate the association between pattern and duration of breastfeeding and consumption of fruits and vegetables in children aged between 4 and 7 years. We conducted a secondary analysis using data from a former randomized clinical trial with 323 adolescent mothers, their children, and maternal grandmothers, when they cohabited. Information on infant feeding was collected monthly during the first 6 months of life, every two months until the child was 1 year old over and when children were between 4 and 7 years old. The associations between duration of breastfeeding and exclusive breastfeeding and consumption of fruits and vegetables were tested by a logistic regression model. Approximately 60% and 45% of children consumed fruits and vegetables, respectively, five or more times a week. Consumption of vegetables among 4-7-year-old children was higher in children who were breastfed for 12 months or longer (OR 2.7; 95%CI 1.49-4.93); however, exclusive breastfeeding duration did not have a significant association with consumption of vegetables (OR 1.5; 95%CI 0.70-3.04). There was no association between weekly consumption of fruits and duration of breastfeeding (OR 1.3; 95%CI 0.71-2.30) or exclusive breastfeeding (OR 0.7; 95%CI 0.34-1.44). Longer duration of breastfeeding was positively associated with consumption of vegetables in children aged 4-7 years; however, there was no association with consumption of fruits. Exclusive breastfeeding duration did not have influence on consumption of fruits or vegetables.

Full Text Available Abstract Background Over recent decades, a dramatic increase in infections caused by multidrug-resistant pathogens has been observed worldwide. The aim of the present study was to investigate the relationship between local resistance bacterial patterns and antibiotic consumption in an intensive care unit in a Romanian university hospital. Methods A prospective study was conducted between 1st January 2012 and 31st December 2013. Data covering the consumption of antibacterial drugs and the incidence density for the main resistance phenotypes was collected on a monthly basis, and this data was aggregated quarterly. The relationship between the antibiotic consumption and resistance was investigated using cross-correlation, and four regression models were constructed, using the SPSS version 20.0 (IBM, Chicago, IL and the R version 3.2.3 packages. Results During the period studied, the incidence of combined-resistant and carbapenem-resistant P. aeruginosa strains increased significantly [(gradient = 0.78, R2 = 0.707, p = 0.009 (gradient = 0.74, R2 = 0.666, p = 0.013 respectively], mirroring the increase in consumption of β-lactam antibiotics with β-lactamase inhibitors (piperacillin/tazobactam and carbapenems (meropenem [(gradient = 10.91, R2 = 0.698, p = 0.010 and (gradient = 14.63, R2 = 0.753, p = 0.005 respectively].

Full Text Available Abstract Background The UK government has announced a tax on sugar-sweetened beverages. The aim of this study was to assess consumption patterns for plain drinking water relative to sugary beverages among UK children. Methods Dietary intake data for 845 children aged 4–13 years came from the nationally representative cross-sectional National Diet and Nutrition Survey, 2008–2011. Beverage categories were drinking water (tap or bottled, milk, 100% fruit juices, soda, fruit drinks, tea, coffee, sports drinks, flavored waters, and liquid supplements. Consumption patterns were examined by age group, gender, household incomes, time and location of consumption, region and seasonality. Total water consumption from drinking water, beverages, and foods, and the water-to-calorie ratios (L/kcal were compared to the EFSA (European Food Safety Authority adequate intake standards. Results Total water intake (1338 ml/d came from plain water (19%, beverages (48%, and food moisture (33%. Plain drinking water provided 258 g/d (241 g/d for children aged 4–8 years; 274 g/d for 9–13 years, mostly (83.8% from tap. Water and beverages supplied 901 g /d of water. Tap water consumption increased with income and was highest in the South of England. The consumption of bottled water, soda, tea and coffee increased with age, whereas milk consumption declined. About 88.7% of children did not meet EFSA adequate intake standards. The daily water shortfall ranged from 322 ml/d to 659 ml/d. Water-to-calorie ratio was 0.845 L/1000 kcal short of desirable levels of 1.0–1.5 L/1000 kcal. Conclusion Total water intake were at 74.8% of EFSA reference values. Drinking water consumption among children in the UK was well below US and French estimates.

Full Text Available Abstract Background Consumption of 100% orange juice (OJ has been positively associated with nutrient adequacy and diet quality, with no increased risk of overweight/obesity in children; however, no one has examined these factors in adults. The purpose of this study was to examine the association of 100% OJ consumption with nutrient adequacy, diet quality, and risk factors for metabolic syndrome (MetS in a nationally representative sample of adults. Methods Data from adults 19+ years of age (n = 8,861 participating in the National Health and Nutrition Examination Survey 2003-2006 were used. The National Cancer Institute method was used to estimate the usual intake (UI of 100% OJ consumption, selected nutrients, and food groups. Percentages of the population below the Estimated Average Requirement (EAR or above the Adequate Intake (AI were determined. Diet quality was measured by the Healthy Eating Index-2005 (HEI-2005. Covariate adjusted logistic regression was used to determine if consumers had a lower odds ratio of being overweight or obese or having risk factors of MetS or MetS. Results Usual per capita intake of 100% OJ was 50.3 ml/d. Among consumers (n = 2,310; 23.8%, UI was 210.0 ml/d. Compared to non-consumers, consumers had a higher (p  Conclusion The results suggest that moderate consumption of 100% OJ should be encouraged to help individuals meet the USDA daily recommendation for fruit intake and as a component of a healthy diet.

Linkages between snack patterns, diet, and obesity in adolescents likely depend on the consumption of main meals, how often snacks are prepared away from home, and whether energy-dense, nutrient-poor snack foods and sugary drinks are frequently consumed. Nutrition-based interventions need to be informed by an understanding of how secular changes in the contribution of snacks to dietary intake may be related to changes in meal frequency as well as how these trends differ by sociodemographic characteristics. To examine secular trends from 1999 to 2010 in meal and snack patterns among adolescents. A repeated cross-sectional design was used. Participants from Minneapolis/St Paul, MN, secondary schools completed classroom-administered surveys and food frequency questionnaires in 1999 (n=2,598) and 2010 (n=2,540). Weekly meal frequencies; number of snacks consumed on school and vacation/weekend days; frequent consumption of snacks prepared away from home (≥3 times/week); and daily servings of energy-dense, nutrient-poor food/drinks that are commonly consumed at snack occasions. Trends from 1999 to 2010 were examined using inverse probability weighting to control for differences in sociodemographic characteristics in the two samples. Mean frequencies of breakfast and lunch increased modestly in the overall population (both P values snacks consumed on schools days (Psnacks prepared away from home, there was a secular decrease in energy-dense, nutrient-poor food/drink consumption (Psnack trends among adolescents suggests the need for targeted efforts to ensure public health messages reach low-income and ethnic/racial minority population subgroups most vulnerable to poor nutrition and the development of obesity.

Global Expanded Nutrient Supply (GENuS Model: A New Method for Estimating the Global Dietary Supply of Nutrients.

Directory of Open Access Journals (Sweden)

Matthew R Smith

Full Text Available Insufficient data exist for accurate estimation of global nutrient supplies. Commonly used global datasets contain key weaknesses: 1 data with global coverage, such as the FAO food balance sheets, lack specific information about many individual foods and no information on micronutrient supplies nor heterogeneity among subnational populations, while 2 household surveys provide a closer approximation of consumption, but are often not nationally representative, do not commonly capture many foods consumed outside of the home, and only provide adequate information for a few select populations. Here, we attempt to improve upon these datasets by constructing a new model--the Global Expanded Nutrient Supply (GENuS model--to estimate nutrient availabilities for 23 individual nutrients across 225 food categories for thirty-four age-sex groups in nearly all countries. Furthermore, the model provides historical trends in dietary nutritional supplies at the national level using data from 1961-2011. We determine supplies of edible food by expanding the food balance sheet data using FAO production and trade data to increase food supply estimates from 98 to 221 food groups, and then estimate the proportion of major cereals being processed to flours to increase to 225. Next, we estimate intake among twenty-six demographic groups (ages 20+, both sexes in each country by using data taken from the Global Dietary Database, which uses nationally representative surveys to relate national averages of food consumption to individual age and sex-groups; for children and adolescents where GDD data does not yet exist, average calorie-adjusted amounts are assumed. Finally, we match food supplies with nutrient densities from regional food composition tables to estimate nutrient supplies, running Monte Carlo simulations to find the range of potential nutrient supplies provided by the diet. To validate our new method, we compare the GENuS estimates of nutrient supplies against

In China market, people have many choices for air conditioning of their apartments, including heat-pump systems or gas-fired boilers for heating and air conditioners for cooling. Domestic hot water is usually provided by domestic water heaters making use of electricity or natural gas, which are known for their great energy costs. These systems consume much energy and increase the total cost of required domestic energy. A novel system combining heat pump with water heater is proposed in this paper, and it is named domestic energy system. The system can realize the provision of space heating, cooling and domestic hot water throughout a year. Based on different types of air conditioners, space heating equipments and water heaters, domestic energy consumption patterns are concluded to be eight categories. This study describes and compares the eight domestic energy consumption patterns by economic analysis and prime energy analysis method. Results show that the domestic energy system can provide good economy and save energy significantly. Furthermore, exergy analysis method is employed to compare the exergy efficiencies of different energy consumption systems. The results show that the domestic energy system has the highest energy conversion efficiency and can make remarkable contribution to social energy saving.

Consumption of 100% orange juice (OJ) has been positively associated with nutrient adequacy and diet quality, with no increased risk of overweight/obesity in children; however, no one has examined these factors in adults. The purpose of this study was to examine the association of 100% OJ consumption with nutrient adequacy, diet quality, and risk factors for metabolic syndrome (MetS) in a nationally representative sample of adults. Data from adults 19+ years of age (n = 8,861) participating in the National Health and Nutrition Examination Survey 2003-2006 were used. The National Cancer Institute method was used to estimate the usual intake (UI) of 100% OJ consumption, selected nutrients, and food groups. Percentages of the population below the Estimated Average Requirement (EAR) or above the Adequate Intake (AI) were determined. Diet quality was measured by the Healthy Eating Index-2005 (HEI-2005). Covariate adjusted logistic regression was used to determine if consumers had a lower odds ratio of being overweight or obese or having risk factors of MetS or MetS. Usual per capita intake of 100% OJ was 50.3 ml/d. Among consumers (n = 2,310; 23.8%), UI was 210.0 ml/d. Compared to non-consumers, consumers had a higher (p juice, whole fruit, and whole grain.

Full Text Available Abstract Background The Alcohol Toolkit Study (ATS is a monthly survey of approximately 1700 adults per month aged 16 years of age or more in England. We aimed to explore patterns of alcohol consumption and motivation to reduce alcohol use in England throughout the year. Methods Data from 38,372 participants who answered questions about alcohol consumption (March 2014 to January 2016 were analysed using weighted regression using the R survey package. Questions assessed alcohol consumption (AUDIT-C and attempts to reduce consumption. Results Sixty-seven percent of participants reported using alcohol, with a small negative trend of about 2 % reduction over 12 months in the studied period (P < 0.01. These include ~25 % higher risk drinkers and ~10 % regular binge drinkers. About 20 % of higher risk drinkers indicated they were attempting to reduce their alcohol consumption. Attempts were lowest in December (−20 %; 95 % CI 0–35 %, but increases significantly in January (+41 %; 95 % CI 16–73 % compared with other months (P < 0.001, indicating a small net gain; at least in attempts to reduce. However, there was no evidence that the increased motivation in January was accompanied by a reported decrease in consumption or binge drinking events. This could be an artefact of the use of AUDIT questions, but could also reflect a disconnect between attempting to reduce alcohol consumption and subsequent change; maybe as a result of lack of continuing support. Conclusions January is associated with moderate increased attempts to reduce alcohol consumption. However, we find little evidence of a change in alcohol consumption. In part, this may be due to temporal insensitivity of the AUDIT questions.

Energy is one of the most important ingredients required to alleviate poverty and realize socio-economic and human development, which is directly interconnected to the prominence of life in rural areas. An extensive survey on household energy consumption pattern interrelating socio-economic and demographic factors was carried out in the disregarded villages of Bangladesh using stratified random sampling technique of 120 households. This paper focuses on household energy consumption, various combinations of fuels and their expenditure in the study area. Biomass, kerosene, electricity, LPG and candle were found as the energy carrier used in the rural households in this study. The study shows that 92% households use biomass, 28% LPG, 89% kerosene, 78% electricity and 27% candle as fuel types. It was found that 56% households collected biomass from their own homesteads and/or agricultural lands. Bamboo, branches, cow dung, firewood, rice husk, leaves and twigs and straw were found as the biomass for household energy use. Average monthly household expenditure for total energy was US$ 9.67 (SE, 0.31) per month while the total monthly income of the household was US$ 123 (SE, 2.53). The ratio of the total monthly energy expenditure to the total monthly income was 7.86%. The study will be helpful to understand the energy consumption system and its expenditure in the rural areas of Bangladesh and to the policy formulation for energy production, consumption and utilization.

Transitions in nutrition patterns tend to emerge through industrialization and economic development. We hypothesized that the dietary patterns among South Korean adults who were 20 years or older have changed significantly from 1998 to 2010. Herein, a repeated cross-sectional analysis of data was followed for 140601 adults. We noted changes in consumption, after adjusting for age, sex, body mass index, and exercise, and tested the trends across the study period. Factor and cluster analyses were used to derive dietary patterns. A decrease in traditional Korean food consumption, including cereals, vegetables (252-176 g), and Kimchi (127-82 g), occurred, whereas fruit (172-252 g), egg, and fried food intakes increased (P dietary patterns: "Korean" diet (rice, vegetables, and Kimchi), "Western" diet (soda, eggs, and oil), and "New" diet (low sugar and high fruit and dairy product intakes). Compared to 1998, approximately 40% of participants still followed a Korean diet in 2010. Interestingly, the popularity of the Western diet fell by approximately 20%, whereas the new diet pattern increased 2-fold over the study period. Overall, these data show secular trends in dietary patterns that included a preservation of the traditional Korean diet and the emergence of a new diet pattern, and it demonstrated a unique transition in food and nutrient intakes in Korea.

Background : The association between different types of breakfast meals and nutrient intakes has been studied to a lesser extent. Objective : This study compared nutrient intakes at breakfast and throughout the day between Malaysian children who consumed ready-to-eat cereals (RTEC) and those who did not. Methods : Anthropometric and dietary data for 1955 children aged 6-12 years from the MyBreakfast study were used in the analysis. Results : Overall, 18% of the children consumed RTEC at breakfast on at least one of the recall days. RTEC consumption was associated with younger age, urban areas, higher income and education level of parents. Among consumers, RTEC contributed 10% and 15% to daily intakes of calcium and iron respectively and ≥20% to daily intakes of vitamin C, thiamin, riboflavin and niacin. RTEC consumers had significantly higher mean intakes of vitamin C, thiamin, riboflavin, niacin, calcium, iron and sugar but lower intakes of fat and sodium than non-RTEC consumers at breakfast and for the total day. Conclusion : Consumption of fortified RTEC at breakfast was associated with lower fat and sodium intakes and higher intakes of several micronutrients both at breakfast and for the total day. However, total sugar intakes appeared to be higher.

Domestic water cycle systems serving as one critical component of artificial water cycle at the catchment's scale, is so closely related to public healthy, human rights and social-economic development, and has gained the highest priority in strategic water resource and municipal infrastructure planning. In this paper, three basic patterns of domestic water cycle systems are identified and analyzed, including rural domestic water system (i.e. primary level), urban domestic water system (i.e. intermediate level) and metropolitan domestic water system (i.e. senior level), with different "abstract-transport-consume-discharge" mechanisms and micro-components of water consumption (such as drinking, cooking, toilet flushing, showering or cleaning). The rural domestic water system is general simple with three basic "abstract-consume-discharge" mechanisms and micro-components of basic water consumption such as drinking, cooking, washing and sanitation. The urban domestic water system has relative complex mechanisms of "abstract-supply-consume-treatment-discharge" and more micro-components of water consumption such as bath, dishwashing or car washing. The metropolitan domestic water system (i.e. senior level) has the most complex mechanisms by considering internal water reuse, external wastewater reclamation, and nutrient recycling processes. The detailed structures for different water cycle pattern are presented from the aspects of water quantity, wastewater quality and nutrients flow. With the speed up of urbanization and development of social-economy in China, those three basic patterns are interacting, transforming and upgrading. According to the past experiences and current situations, urban domestic water system (i.e. intermediate level) is the dominant pattern based on indicator of system number or system scale. The metropolitan domestic water system (i.e. senior level) is the idealized model for the future development and management. Current domestic water system

To find out how the consumption of organic food during pregnancy is associated with consumer characteristics, dietary patterns and macro- and micronutrient intakes. Cross-sectional description of consumer characteristics, dietary patterns and macro- and micronutrient intakes associated with consumption of organic food during pregnancy. Healthy, pregnant women recruited to a prospective cohort study at midwives' practices in the southern part of the Netherlands; to enrich the study with participants adhering to alternative lifestyles, pregnant women were recruited through various specific channels. Participants who filled in questionnaires on food frequency in gestational week 34 (n 2786). Participant groups were defined based on the share of organic products within various food types. Consumers of organic food more often adhere to specific lifestyle rules, such as vegetarianism or anthroposophy, than do participants who consume conventional food only (reference group). Consumption of organic food is associated with food patterns comprising more products of vegetable origin (soya/vegetarian products, vegetables, cereal products, bread, fruits, and legumes) and fewer animal products (milk and meat), sugar and potatoes than consumed in conventional diets. These differences translate into distinct intakes of macro- and micronutrients, including higher retinol, carotene, tocopherol and folate intakes, lower intakes of vitamin D and B12 and specific types of trans-fatty acids in the organic groups. These differences are seen even in groups with low consumption of organic food. Various consumer characteristics, specific dietary patterns and types of food intake are associated with the consumption of organic food during pregnancy.

Full Text Available To determine the sugar consumption pattern of the school children in Belgaum city and to organize for a diet-counseling program. Easy availability of sugar containing food and high consumption of these sweets if continued unabated, the dental caries among children would become a major public health problem. In this instance, Dietary counseling can be just appropriate to inhibit the carious process. 342 school children aged 13 years, from four schools in Belgaum city participated in the study. The pattern of sugar consumption was assessed using a 4-day diet diary. Analysis was done according to the method described by Nizel and Papas (Nutrition in clinical dentistry, 1989, 277 and the variables were: the sweet score, At meal sugar exposure (AMSE, Between meal sugar exposure (BMSE and Total sugar exposure (TSE. The mean, standard deviation and/or frequency were calculated for all variables. Student′s t-test was used to statistically analyze the gender difference.

Results: Although the best known and followed patterns are the restriction in sodium intake, weight control, and moderation in alcohol consumption; improving diet (increasing consumption of cereals, vegetables, fruits...) and physical activity seem to have a major impact on the control of blood pressure, also consume less saturated fat (with increased MUFA and omega-3), adequate intake of calcium, magnesium, protein, vitamin D and fiber and improving the antioxidant capacity of the diet can have great importance in fighting the problem of hypertension. Given that the average Spanish diet does not meet the advised requirements for many of the nutrients mentioned as favorable in control of the blood pressure, an approximation of the diet to the theoretical ideal can be very helpful in the fight against this problem that has great health impact. Conclusions: Improving feeding, increasing the intake of vegetables, legumes, whole grains, dairy, fish, avoiding an inadequate supply of nutrients (especially calcium, magnesium, protein, and vitamin D) can have a greater benefit in controlling blood pressure, than most widespread monitoring restrictive guidelines in practice.

meat products have been recognized to be adequate matrix for incorporating functional ingredients. The impact of meat products formulated by replacing animal fat with a combination of olive, linseed and fish oils on energy and nutrient intakes and anthropometric measurements were tested in a non-randomized-controlled- sequential study. eighteen male volunteers at high-CVD risk consumed weekly 200 g frankfurters and 250 g pâtés during three 4-wk periods (reduced fat (RF); n3-enriched- RF (n-3RF), and normal fat (NF)), separated by 4-wk washout. Energy and nutrient intakes, healthy eating index (HEI), and anthropometric changes were evaluated. body fat mass rate-of-change and the waist/ hip ratio significantly differs (p = 0.018 and p = 0.031, respectively) between periods, decreasing body fat mass, waist circumference and waist/hip ratio in RF period and increasing body fat mass in NF one (all p = 0.05). Significant inverse correlations were observed between rate- of-change of BMI and ideal body weight with dietary carbohydrate/SFA ratio in n-3RF period (p = 0.003 and p = 0.006, respectively). Initial diets presented low HEIs (means Product consumption improved dietary Zn, Ca, retinol equivalent, folate and vitamin B12 contents in all periods, and ameliorated n-3 PUFA contents and n-6/n-3 PUFA ratio over the n-3RF period. improved-fat meat products appear as functional foods for overweight/obeses since their consumption improved selected body-fat markers, without affecting HEI, macronutrient and energy but their n-3 PUFA and n6/n3 ratio intakes.

Nowadays India is undergoing an impressive economic growth accompanied by a very slow decline, almost stagnation, in malnutrition levels. In developing countries, studies on dietary patterns and their relationship with nutritional status are scarce. Over the years some nutritional studies have been performed to explore different types of food consumed in various Indian regions, among different social samples. The aim of the present paper is to review and describe trends in food and nutrition intake patterns in the different states of India. The review was carried out in PubMed, using the advanced research criteria: [food* OR ("meal pattern*") OR ("eating pattern*")] AND ("nutrient intake") AND India*. PubMed research gave back 84 results and out of these, 7 papers due to their focus on food intake and consumption levels in India have been included in this study. Food intake patterns showed that most of the Indians are vegetarians and that food items rich in micronutrients (pulses, other vegetables, fruits, nuts, oilseeds and animal foods) are generally consumed less frequently. Poor and monotonous cereals-based diet may promote inadequate nutrition intakes according to Recommended Daily Allowance (RDA) standards.

Full Text Available Mercury exposure through the consumption of fish and shellfish represents a significant public health concern in the United States. Recent research has demonstrated higher seafood consumption and subsequent increased risk of methylmercury exposure among subpopulations living in coastal areas. The identification of high concentrations of total mercury in blood and skin among resident Atlantic bottlenose dolphins (Tursiops truncatus in the Indian River Lagoon (IRL, a coastal estuary in Florida, alerted us to a potential public health hazard in the contiguous human population. Therefore, we analyzed hair mercury concentrations of residents living along the IRL and ascertained their sources and patterns of seafood consumption. The total mean mercury concentration for 135 residents was 1.53 ± 1.89 µg/g. The concentration of hair mercury among males (2.02 ± 2.38 µg/g was significantly higher than that for females (0.96 ± 0.74 µg/g (p < 0.01. Log transformed hair mercury concentration was significantly associated with the frequency of total seafood consumption (p < 0.01. Individuals who reported consuming seafood once a day or more were 3.71 (95% CI 0.84–16.38 times more likely to have a total hair mercury concentration over 1.0 µg/g, which corresponds approximately to the U.S. EPA reference dose, compared to those who consumed seafood once a week or less. Hair mercury concentration was also significantly higher among individuals who obtained all or most of their seafood from local recreational sources (p < 0.01. The elevated human mercury concentrations mirror the elevated concentrations observed in resident dolphins in the same geographical region. The current study is one of the first to apply the concept of a sentinel animal to a contiguous human population.

The Korean government announced its plan to raise the previous reduction goal of greenhouse gas emission from buildings by 26.9% until 2020 on July 2015. Therefore, policies regarding efficiency in the building energy are implemented fast, but the level of building owners and market understanding is low in general, and the government service system which supports decision making for implementing low-energy buildings has not been provided yet. The purpose of this study is to present the design direction for establishing user customized building energy database to perform a role to provide autonomous ecosystem of low-energy buildings. In order to reduce energy consumption in buildings, it is necessary to carry out the energy performance analysis based on the characteristics of target building. By analysing about 20-thousand cases of the amount of housing energy consumption in Korea, this study suggested the real energy consumption pattern by building types. Also, the energy performance of a building could be determined by energy consumption, but previous building energy consumption analysis programs required expert knowledge and experience in program usage, so it was difficult for normal building users to use such programs. Therefore, a measure to provide proper default using the level of data which general users with no expert knowledge regarding building energy could enter easily was suggested in this study.

The concept of "food deserts" has been widely used in Western countries as a framework to identify areas with constrained access to fresh and nutritious foods, providing guidelines for targeted nutrition and public health programs. Unlike the vast amount of literature on food deserts in a Western context, only a few studies have addressed the concept in an East Asian context, and none of them have investigated spatial patterns of unhealthy food consumption from a South Korean perspective. We first evaluated the applicability of food deserts in a Korean setting and identified four Korean-specific unhealthy food consumption indicators, including insufficient food consumption due to financial difficulty, limited consumption of fruits and vegetables, excessive consumption of junk food, and excessive consumption of instant noodles. The KNHANES 2008-2012 data in Seoul were analyzed with stratified sampling weights to understand the trends and basic characteristics of these eating patterns in each category. GIS analyses were then conducted for the data spatially aggregated at the sub-district level in order to create maps identifying areas of concern regarding each of these indicators and their combinations. Despite significant reduction in the rate of food insufficiency due to financial difficulty, the rates of excessive consumption of unhealthy foods (junk food and instant noodles) as well as limited consumption of fruits and vegetables have increased or remained high. These patterns tend to be found among relatively younger and more educated groups, regardless of income status. A GIS-based analysis demonstrated several hotspots as potential "food deserts" tailored to the Korean context based on the observed spatial patterns of undesirable food consumption. These findings could be used as a guide to prioritize areas for targeted intervention programs to facilitate healthy food consumption behaviors and thus improve nutrition and food-related health outcomes.

Little is known about overweight adolescent dietary consumption patterns, with challenges to collecting meaningful data making it difficult to develop targeted obesity interventions. The present study aimed to examine the timing and consumption of fruit, vegetables and junk food by time of the day and day of the week. Overweight adolescents (n = 61), aged 12-16 years, completed 3-day food records. Negative binomial and binary logistic regression using generalised estimating equations were used to compare the amount and likelihood of the consumption of each food group between time periods. Overweight adolescent girls were more likely to eat fruit on weekdays than weekends [odds ratio (OR) = 5.0. P dinner was the meal where girls were most likely to consume vegetables (OR = 3.0, P = 0.009) and when boys consumed the most vegetables (IRR = 30.9, P = 0.006). Fast food consumption was most likely for girls at dinner on the weekend (OR = 9.6, P = 0.042), whereas fast food intake for boys increased overall on the weekend (IRR = 3.6, P = 0.001). Intake of 'other junk' (e.g. crisps) peaked during school hours for girls (IRR = 7.2, P < 0.001) and sugar-sweetened beverage consumption increased for boys on the weekend (IRR = 3.3, P = 0.001). Overall, trends in fruit intake showed opposing times for high and low consumption compared to vegetable intake. These results represent the next step in using time of day and day of week consumption patterns to develop targeted, evidence-based dietary messages for interventions in overweight adolescents. © 2014 The British Dietetic Association Ltd.

This cross-sectional study investigated patterns of alcohol consumption among patients enrolled in the Family Health Program (FHP) in a city in Southeast Brazil, as well as the detection of such consumption by FHP professionals. A total of 932 adult patients were evaluated from November 2010 to November 2011. Of this total, 17.5% were considered at risk for hazardous drinking (AUDIT ≥ 8); increased risk was associated with male gender, younger age, and chronic illness. The CAGE questionnaire was positive in 98 patients (10.5%), with a higher proportion in men. Health professionals were more likely to ask about alcohol consumption in men, individuals aged ≥ 55 years, those with chronic illnesses, and heavier drinkers (438/932; 47.8%). Positive diagnosis of alcoholism was more frequent in men, individuals aged 35-54 years, and those with serious alcohol abuse (22/175; 12.6%). The study concluded that alcohol consumption is common among patients treated by FHP teams (although insufficiently recognized by professionals) and that a minority of alcoholics is instructed on the risks of drinking.

To explore knowledge, attitudes and behaviours regarding caloric soft drinks in a group of young adults attending university and to identify opportunities for a health promotion intervention aimed at reducing consumption. In-depth, semi-structured focus groups segmented by gender. Sydney, Australia. Undergraduate University of Sydney students aged 18-30 years (n 35). Social and environmental cues, intrinsic qualities of beverages and personal health beliefs were identified as important influences on consumption. Social cues included settings in which alcohol is usually consumed, socialising with friends, and family influences. Environmental cues included purchasing of fast foods, and ready availability, preferential pricing and promotion of caloric beverages. Reinforcing intrinsic qualities of caloric soft drinks included taste, sugar and caffeine content, and their association with treats and rewards. Major gender differences as well as variations in individual readiness for behaviour change were observed. Raising awareness of the sugar content of various beverages and the potential health impacts associated with their consumption was considered important. The findings provide new insights with important implications for policy and practice, and suggest that there is considerable scope for promoting awareness in this group. Carefully designed social marketing campaigns highlighting the health issues and addressing social and environmental cues relating to caloric soft drink consumption are required. There is a need for gender-differentiated intervention programmes which are both informational and appealing to young adults. Further research is warranted, particularly to investigate beverage consumption relating to fast-food meal deals and young adults' consumption patterns in more depth.

Consumer's preference and consumption pattern of biomass fuel, fuel types and energy use category has been studied in the disregarded villages of Bangladesh. The study was conducted both in the inland and island areas. Biomass energy in the study area was used in domestic cooking, tea stalls, brickfields, bakeries, paddy parboiling and pottery. Assessment of consumption in domestic cooking was done by means of multistage random sampling and that in the tea stalls, brickfields, bakeries, paddy parboiling and pottery by means of complete enumeration of the sampling unit. Based on the homestead size respondents were categorized into small, medium and large and a total of 60 homesteads (30 from inland and another 30 from island areas), 20 from each category were selected randomly for the study. The study revealed that natural gas was quite absent and stems, branches and twigs, leaves of trees, agricultural residues, shell and coir of coconut, saw dust, brush wood, rhizomes of bamboo, and cowdung were the biomass fuel used by the respondent. Nine fuelwood species were identified as the most preferred in the study area. Consumption pattern was mostly traditional. Each year preceding the rainy season cyclonic action damages a large quantity of biomass energy sources. Though at the initial stage of rainy season (April-May) there remain a more or less good collection of fuelwood to the user as the byproduct of cyclones and storms, the last part of the rainy season (July-August) was identified as the fuel shortage period.

Several studies have suggested differential health effects in relation to different meat composition in Western population. The purpose of the study was to examine secular trends in meat and seafood consumption patterns among Chinese adults between 1991 and 2011. Our longitudinal data are from 21,144 adults aged 18-75 in the China Health and Nutrition Survey, prospective cohort study. We assessed the intakes of meat and subtypes with three 24-h dietary recalls. We conducted multilevel mixed-effect logistic and linear regression models to examine meat consumption dynamics. The proportions of Chinese adults who consumed red meat, poultry and seafood increased from 65.7% in 1991 to 86.1% in 2011, from 7.5 to 20.9% and from 27.4 to 37.8%, respectively. With rapid decrease in meat intakes since 2009, the intakes of total meat, red meat, poultry and seafood among their consumers were 86.7 g/day, 86.4 g/day, 71.0 g/day and 70.3 g/day in 2011, respectively, which were just slightly higher compared with those in 1991. Fatty fresh pork has been predominantly component of total meat overtime, which consituted 54.0% of total meat intake, 80.0% of fresh red meat intake and 98.7% of fatty fresh red meat intake in 2011. Over the past two decades, meat consumption patterns of Chinese adults have been characterized by having a predominant intake of fatty fresh pork, suboptimal intakes of seafood and increased proportion of adults having excessive intakes of red meat and poultry overtime.

Persistent patterns of erosion have emerged in the Ethiopian highlands leading to soil and water conservation practices being implemented throughout the countryside. A common concern is the loss of soil fertility and loss of soil water. This study investigates the spatial patterns of soil nutrients and water table depths in a small sub-watershed in the northwestern Ethiopian highlands. NPK, a particularly important group of nutrients for inorganic fertilizer considerations, did not follow a consistent trend as a group along and across slope and land use transects. Whereas nitrogen content was greatest in the upslope regions (~0.1% TN), available phosphorus had comparably similar content in the different slope regions throughout the watershed (~2.7 mg/kg). The exchangeable cations (K, Ca, Mg) did increase in content in a downslope direction (in most cases though, they were highest in the middle region) but not consistently later in the season. On average, calcium (40 cmol/kg), magnesium (5 cmol/kg), and potassium (0.5 cmol/kg) were orders of magnitudes different in content. The perched water table in different areas of the watershed showed a very distinct trend. The lower part of the sub-watershed had shallower levels of water table depths (less than 10 cm from the surface) than did the upper parts of the sub-watershed (usually greater than 120 cm from the surface). The middle part of the sub-watershed had water table depths located at 40 to 70 cm below the surface. These results show how the landscape slope position and land use may be important for planning where and when soil nutrients and water would be expected to be appropriately "conserved" or stored.

It is expected that a dietary intervention based on the traditional Mediterranean food pattern should be associated with a reduction in fast-food consumption but this has never been tested before. We assessed the impact of a 12-week dietary intervention, promoting the adoption of a Mediterranean food pattern, on fast-food consumption among seventy-one healthy women aged between 30 and 65 years. The dietary intervention consisted of two group sessions and seven individual sessions with a dietitian. To determine the Mediterranean dietary score (MedScore) and fast-food consumption, an FFQ was administered. During the 12-week intervention, the MedScore significantly increased (from 21.1 (SD 3.6) units at baseline to 28.6 (SD 4.4) units at week 12, P food consumption significantly decreased (from 51.7 (SD 46.4) g/d at baseline to 20.5 (SD 18.2) g/d at week 12, P food at baseline decreased their fast-food consumption to the most (r - 0.50, P food consumption changes, it was found that only the subgroup of women which increased the most their MedScore and decreased the most their fast-food consumption experienced a significant decrease in BMI (P food pattern led to a decrease in fast-food consumption among healthy women even if it was not a specific target of the intervention. Dietary strategies for increasing intake of healthy foods may be a useful approach for decreasing intake of less healthy foods.

Conditional transfer programs are increasingly popular, but the impact on household nutrient consumption has not been studied. We evaluated the impact of the Programa de Apoyo Alimentario (PAL), a cash and in-kind transfer program, on the energy and nutrient consumption of poor rural households in Mexico. The program has been shown to reduce poverty. Beneficiary households received either a food basket (including micronutrient-fortified milk) or cash. A random sample of 206 rural communities in Southern Mexico was randomly assigned to 1 of 4 groups: a monthly food basket with or without health and nutrition education, a cash transfer with a cost to the government equivalent to the food basket (14 USD/mo) with education, or control. The impact after 14 mo of exposure was estimated in a panel of 5823 households using a double difference regression model with household fixed effects. PAL was associated with increases (P consumption of total energy (5-9%), energy from fruits and vegetables (24-28%), and energy from animal source foods (24-39%). It also affected iron, zinc, and vitamin A and C consumption (P consumption of energy and all nutrients was greater in the food basket group (P energy-deficient should be carefully redesigned to ensure that pulling poor families out of poverty leads to improved micronutrient intake but not to increased energy consumption.

Background Bread types with high contents of whole grains and rye are associated with beneficial health effects. Consumer characteristics of different bread consumption patterns are however not well known. Objective To compare bread consumption patterns among Swedish adults in relation to selected socio-demographic, geographic, and lifestyle-related factors. For selected consumer groups, the further aim is to investigate the intake of whole grains and the context of bread consumption, that is, where and when it is consumed. Design Secondary analysis was performed on bread consumption data from a national dietary survey (n=1,435). Respondents were segmented into consumer groups according to the type and amount of bread consumed. Multiple logistic regressions were performed to study how selected socio-demographic, geographic, and lifestyle-related factors were associated with the consumer groups. Selected consumption groups were compared in terms of whole-grain intake and consumption context. Consumption in different age groups was analysed more in detail. Results One-third of the respondents consumed mainly white bread. Socio-demographic, geographic, and healthy-lifestyle-related factors were associated with the bread type consumed. White bread consumption was associated with younger age groups, less education, children in the family, eating less fruit and vegetables, and more candy and snacks; the opposite was seen for mainly whole-grain bread consumers. Older age groups more often reported eating dry crisp bread, whole-grain bread, and whole-grain rye bread with sourdough whereas younger respondents reported eating bread outside the home, something that also mainly white bread eaters did. Low consumers of bread also consumed less whole grain in total. Conclusions Traditional bread consumption structures were observed, as was a transition among young consumers who more often consumed fast food bread and bread outside the home, as well as less rye and whole

The main message in this paper is that the discussion on sustainable consumption should also incorporate the consumption that occurs in relation to work and, more generally, the relationship between consumption at work and consumption at home. I start by considering how domestic consumption...... is encouraged by work-related factors and continue to consider how consumption activities occur in the workplace, so illustrating that production and consumption are intertwined. The main part of the paper deals in detail with the conceptual distinction between production and consumption. Inspiration is drawn...... from both ecology and economics with focus on some important predecessors for ecological economics. I conclude with reflections on how to proceed with consumption studies to provide the basis for promoting more sustainable life patterns....

Nutrient Shielding in Clusters of Cells

Science.gov (United States)

Lavrentovich, Maxim O.; Koschwanez, John H.; Nelson, David R.

2014-01-01

Cellular nutrient consumption is influenced by both the nutrient uptake kinetics of an individual cell and the cells’ spatial arrangement. Large cell clusters or colonies have inhibited growth at the cluster's center due to the shielding of nutrients by the cells closer to the surface. We develop an effective medium theory that predicts a thickness ℓ of the outer shell of cells in the cluster that receives enough nutrient to grow. The cells are treated as partially absorbing identical spherical nutrient sinks, and we identify a dimensionless parameter ν that characterizes the absorption strength of each cell. The parameter ν can vary over many orders of magnitude between different cell types, ranging from bacteria and yeast to human tissue. The thickness ℓ decreases with increasing ν, increasing cell volume fraction ϕ, and decreasing ambient nutrient concentration ψ∞. The theoretical results are compared with numerical simulations and experiments. In the latter studies, colonies of budding yeast, Saccharomyces cerevisiae, are grown on glucose media and imaged under a confocal microscope. We measure the growth inside the colonies via a fluorescent protein reporter and compare the experimental and theoretical results for the thickness ℓ. PMID:23848711

Although fortified products have played an increasing role in food marketing since the 1980s in Germany, data as to the consumption of fortified food is sparse. To assess long-term data on changes in fortified food supply or consumption patterns, nutrient intake, and time trends in the DONALD Study (Dortmund Nutritional and Anthropometric Longitudinally Designed Study). Between 1985 and 2000 consumption of nutrient intake (total and from fortified foods) was evaluated and time trends in energy and nutrient intake were assessed on the basis of 3-day weighed dietary records (n = 4193) of 2-14 year-old males (n = 383) and females (n = 404) enrolled in the DONALD Study. Nutrient intake was expressed as percentage of the current German recommendations. Food products were defined as fortified if enriched with at least one of the following nutrients: Vitamin A or provitamin A carotenoids (summarised as Vitamin A), Vitamins E, B1, B2, B6, C, niacin, folate, calcium or iron. Nutrient supplements and medicine were excluded from this evaluation. Time trends were analysed using linear and non-linear regression models (PROC MIXED, SAS 6.12). In percent of German references [3], non-fortified food contributed to folate intake by 20-30%, to Vitamin E by about 40%, to Vitamin B1 by 50-65%, to Vitamin A, C, B2, calcium, iron by about 65-95%, and to Vitamin B6 and niacin intake by 100% and more. Fortified food alone provided no more than 5% of calcium intake, about 10-20% of iron, Vitamin A and folate intake, up to 40-50% of Vitamin C, B1, B2, E, niacin and up to 80% of Vitamin B6 intake. During the 15 year period of the DONALD Study with total food, we only found a significant linear time trend for Vitamin C, whereas significant non-linear time trends were found for calcium, Vitamin E, B1, B2, B6, niacin and folate. In the latter there was a uniform increase until 1994 and a decrease thereafter. For iron and Vitamin A no significant time trend could be identified. Only iron and

Evidence suggests that processed red meat consumption is a risk factor for CVD and type 2 diabetes (T2D). This analysis investigates the association between dietary patterns, their processed red meat contributions, and association with blood biomarkers of CVD and T2D, in 786 Irish adults (18-90 years) using cross-sectional data from a 2011 national food consumption survey. All meat-containing foods consumed were assigned to four food groups (n 502) on the basis of whether they contained red or white meat and whether they were processed or unprocessed. The remaining foods (n 2050) were assigned to twenty-nine food groups. Two-step and k-means cluster analyses were applied to derive dietary patterns. Nutrient intakes, plasma fatty acids and biomarkers of CVD and T2D were assessed. A total of four dietary patterns were derived. In comparison with the pattern with lower contributions from processed red meat, the dietary pattern with greater processed red meat intakes presented a poorer Alternate Healthy Eating Index (21·2 (sd 7·7)), a greater proportion of smokers (29 %) and lower plasma EPA (1·34 (sd 0·72) %) and DHA (2·21 (sd 0·84) %) levels (Pprocessed red meat consumption as a risk factor for CVD and T2D may need to be re-assessed.

Saranga José, Yonss; Dietze, Heiner; Oschlies, Andreas

2017-03-01

Ocean eddies can both trigger mixing (during their formation and decay) and effectively shield water encompassed from being exchanged with ambient water (throughout their lifetimes). These antagonistic effects of eddies complicate the interpretation of synoptic snapshots typically obtained by ship-based oceanographic measurement campaigns. Here we use a coupled physical-biogeochemical model to explore biogeochemical dynamics within anticyclonic eddies in the eastern tropical South Pacific Ocean. The goal is to understand the diverse biogeochemical patterns that have been observed at the subsurface layers of the anticyclonic eddies in this region. Our model results suggest that the diverse subsurface nutrient patterns within eddies are associated with the presence of water masses of different origins at different depths.

The imprint of crop choice on global nutrient needs

International Nuclear Information System (INIS)

Jobbágy, Esteban G; Sala, Osvaldo E

2014-01-01

Solutions to meet growing food requirements in a world of limited suitable land and degrading environment focus mainly on increasing crop yields, particularly in poorly performing regions, and reducing animal product consumption. Increasing yields could alleviate land requirements, but imposing higher soil nutrient withdrawals and in most cases larger fertilizer inputs. Lowering animal product consumption favors a more efficient use of land as well as soil and fertilizer nutrients; yet actual saving may largely depend on which crops and how much fertilizer are used to feed livestock versus people. We show, with a global analysis, how the choice of cultivated plant species used to feed people and livestock influences global food production as well as soil nutrient withdrawals and fertilizer additions. The 3 to 15-fold differences in soil nutrient withdrawals per unit of energy or protein produced that we report across major crops explain how composition shifts over the last 20 years have reduced N, maintained P and increased K harvest withdrawals from soils while contributing to increasing dietary energy, protein and, particularly, vegetable fat outputs. Being highly variable across crops, global fertilization rates do not relate to actual soil nutrient withdrawals, but to monetary values of harvested products. Future changes in crop composition could contribute to achieve more sustainable food systems, optimizing land and fertilizer use. (letter)

Globally, alcohol-abuse is a major cause of mortality and morbidity. Consumption of alcohol has increased in India in the recent decades. It is imperative to know the patterns of alcohol consumption among different types of consumers to launch a well-planned nationwide programme for the prevention and control of this devastating social pathology. This community-based, cross-sectional study was undertaken to identify the patterns of alcohol intake among different types of alcohol consumers and to assess the clinical signs of chronic harmful alcohol-use. A predesigned, pretested, semi-structured alcohol-use disorders identification test (AUDIT) questionnaire was used for interviewing males, aged >18 years, selected by random sampling from an updated household list of a randomly-selected sector of the service area of the Urban Health Centre in Chetla, Kolkata, West Bengal, India. Written informed consents were obtained from all the respondents. Relevant clinical examination for chronic harmful alcohol-use was done according to the AUDIT clinical screening procedures. The results revealed that 65.8% (150/228) were current consumers of alcohol; 14% were alcohol-dependents; 8% were hazardous or harmful consumers, and 78% were non-hazardous non-harmful consumers. The mean age of the respondents at the initiation of drinking alcohol was 20.8+5.9 years. Eighty-six percent of dependents (n=21) took both Indian-made foreign liquor and locally-made alcoholic beverages. The proportions of alcohol consumers who drank alone among alcohol-dependents, hazardous or harmful consumers, and non-hazardous non-harmful consumers were 71.4%, 50%, and 7.7% respectively, and the difference was significant (p<0.01). Forty-one percent of the consumers drank at public places and workplaces, which may be socially harmful. About 38% of the dependents purchased alcohol from unlicensed liquor shops. Only 16% expressed concerns for their drinking habit mainly to the past illness. The proportion of

Ecosystems in the Central Asian Plateau, which includes the Mongolian Plateau, are becoming increasingly sensitive to human interventions, leading to deterioration of already fragile ecosystems. The goal of this paper is to illustrate human dependence on an ecosystem by identifying patterns of resource consumption in this region and investigating the knowledge and perceptions of herders living in these ecosystems. Data on consumption in the two regions were collected using structured questionnaires delivered to a total of 252 herders from Mongolia and China's Inner Mongolia. Meat and other animal products remain the dominant food items for most households, accompanied by various vegetables and cereals. This unbalanced diet leads to excessive consumption of protein and fat from animal sources. The major energy sources used by herders are fuelwood, animal dung, crop residues, and dry grass, but consumption patterns differed between the two areas. Mongolian herders rely more heavily on livestock for meeting their consumption needs than herders in Inner Mongolia. Herder knowledge and perceptions of ecosystem conditions and consumption of resources differed between Mongolia and Inner Mongolia, reflecting the influence of different state policies. The data reported and the conclusions drawn are relevant for developing resource management policies for the Mongolian Plateau, but also provide useful insights for any region where livestock production dominates the use of rangeland resources.

2008-01-01

In a diary-survey study in 234 households with children aged 4-12 years, we investigated the associations between children's exposure to food advertising and their consumption of (a) advertised food brands, (b) advertised energy-dense food product categories, and (c) food products overall. Relations were examined using multiple hierarchical regression analysis, while controlling for various child (i.e., age, sex, television viewing time) and family variables (i.e., family income and consumption-related communication styles). Results showed that children's exposure to food advertising was significantly related to their consumption of advertised brands (beta=.21) and energy-dense product categories (beta=.19). The relation between advertising exposure and overall food consumption only held in lower-income families (beta=.19). In addition, consumption-related family communication was an important moderator of the relations between advertising and the food consumption variables. Socio-oriented family communication (i.e., striving for harmony and conformity) was particularly successful in reducing these relations. In conclusion, consistent with communication theories predicting spill-over effects of advertising, the impact of television food advertising exceeded the advertised brand and generalized to more generic unhealthy consumption patterns. Theoretical and societal consequences, as well as the important role of the family are discussed.

Water Quality Protection from Nutrient Pollution: Case ...

Science.gov (United States)

Water bodies and coastal areas around the world are threatened by increases in upstream sediment and nutrient loads, which influence drinking water sources, aquatic species, and other ecologic functions and services of streams, lakes, and coastal water bodies. For example, increased nutrient fluxes from the Mississippi River Basin have been linked to increased occurrences of seasonal hypoxia in northern Gulf of Mexico. Lake Erie is another example where in the summer of 2014 nutrients, nutrients, particularly phosphorus, washed from fertilized farms, cattle feedlots, and leaky septic systems; caused a severe algae bloom, much of it poisonous; and resulted in the loss of drinking water for a half-million residents. Our current management strategies for point and non-point source nutrient loadings need to be improved to protect and meet the expected increased future demands of water for consumption, recreation, and ecological integrity. This presentation introduces management practices being implemented and their effectiveness in reducing nutrient loss from agricultural fields, a case analysis of nutrient pollution of the Grand Lake St. Marys and possible remedies, and ongoing work on watershed modeling to improve our understanding on nutrient loss and water quality.

The use of fuelwood as a primary source of energy for domestic use is causing severe deforestation in Garhwal Himalaya. In the present study fuelwood consumption patterns have been studied in six villages; two each in tropical (Ganga Bhogpur and Kunow), sub-tropical (Bhainswara and Ghargoan) and temperate (Dhaulana and Chunnikhal) regions under various ecological and socio-economic conditions. The total average fuelwood consumption in the present study was observed to be highest for Ganga Bhogpur (2.52 kg per capita per day) in the tropical region, whereas, lowest for Ghargoan (1.63 kg per capita per day) in the sub-tropical region. The labour energy expenditure for fuelwood collection was greatest for Dhaulana (146.62 MJ per capita per day) in the temperate region, and lowest for Ganga Bhogpur (88.80 MJ per capita per day) in the tropical region. The fuelwood consumption rate oscillated considerably across the different seasons. The tree and shrub species preferred by the inhabitants for fuelwood were Holoptelea integrifolia, Anogeissus latifolia and Lantana camara in the tropical region; A. latifolia, Acacia catechu and Carissa spinarum in the sub-tropical region; and Quercus leucotrichophora, Myrica esculenta and Pyracantha crenulata in the temperate region, respectively.

Annual soil nutrient loss characteristics on typical reforestation patterns in watershed along the Three Gorges Reservoir Area were studied based on runoff plot experiment. Runoff and sediment nutrition content from May to October 2014 of typical reforestation patterns including garden plot (tea garden), forest land (Chinese chestnut) and the original slope farmland were determined and then analyzed. The results showed that: (1) After the Returning Farmland to Forest Project the quantity of annual soil nutrient (nitrogen and phosphorus, the sum of them in sediment and runoff) loss decreased. The output of total nitrogen (TN) was in the order of slope farmland (2 444.27 g x hm(-2)) > tea garden (998.70 g x hm(-2)) > Chinese chestnut forest (532.61 g x hm(-2)), and for total phosphorus (TP) loss was slope farmland (1 690.48 g x hm(-2)) > tea garden (488.06 g x hm(-2)) > Chinese chestnut forest (129.00 g x hm(-2)) . Compared with slope farmland, the load of TN and TP output of reforestation patterns decreased 68.68% and 81.75%, respectively. (2) Compared with slope farmland, available nitrogen loss decreased in reforestation patterns. Total nitrate nitrogen (NO3(-)-N) loss ranked in the order of slope farmland (113.79 g x hm(-2)) > tea garden (73.75 g x hm(-2)) > Chinese chestnut forest (56.06 g x hm(-2)) The largest amount of ammonium nitrogen (NH4(+)-N) was found in tea garden (69.34 g x hm(-2)), then in farmland (52.45 g x hm(-2)), and the least in Chinese chestnut forest (47.23 g x hm(-2)). (3) The main route of NO3(-)-N and NH4(+)-N loss was both through runoff, the quantity of NO3(-)-N and NH4(+)-N output in which accounted for 91.4% and 92.2% of the total, respectively. The quantity of TN and TP in sediment accounted for 86.6% and 98.4% of the total. TN and TP loss showed an extremely significant correlation with sediments, which showed that sediment output was the main approach of TN and TP loss.

Abstract: To explore the effects of soil wetting pattern on soil water-thermal environment and water consumption of cotton root under mulched drip irrigation, a field experiment with three drip intensities (1.69, 3.46 and 6.33 L · h(-1)), was carried out in Shihezi, Xinjiang Autonomous Region. The soil matric potential, soil temperature, cotton root distribution and water consumption were measured during the growing period of cotton. The results showed that the main factor influencing the soil temperature of cotton under plastic mulch was sunlight. There was no significant difference in the soil temperature and root water uptake under different treatments. The distribution of soil matrix suction in cotton root zone under plastic mulch was more homogeneous under ' wide and shallow' soil wetting pattern (W633). Under the 'wide and shallow' soil wetting pattern, the average difference of cotton root water consumption between inner row and outer row was 0.67 mm · d(-1), which was favorable to the cotton growing trimly at both inner and outer rows; for the 'narrow and deep' soil wetting pattern (W169), the same index was 0.88 mm · d(-1), which was unfavorable to cotton growing uniformly at both inner and outer rows. So, we should select the broad-shallow type soil wetting pattern in the design of drip irrigation under mulch.

Nutrition is thought to influence disease status in patients with cystic fibrosis (CF). This cross-sectional study sought to evaluate nutrient intake and anthropometric data from 64 adult outpatients with cystic fibrosis. Nutrient intake from food and supplements was compared with the Dietary Reference Intakes for 16 nutrients and outcomes influenced by nutritional status. Attention was given to vitamin D and calcium given potential skeletal implications due to cystic fibrosis. Measurements included weight, height, body composition, pulmonary function, and serum metabolic parameters. Participants were interviewed about dietary intake, supplement use, pulmonary function, sunlight exposure, and pain. The participants’ mean body mass index (±standard deviation) was 21.8±4.9 and pulmonary function tests were normal. Seventy-eight percent used pancreatic enzyme replacement for malabsorption. Vitamin D deficiency [25-hydroxyvitamin D (25OHD)<37.5 nmol/L] was common: 25 (39%) were deficient despite adequate vitamin D intake. Lipid profiles were normal in the majority, even though total and saturated fat consumption represented 33.0% and 16.8% of energy intake, respectively. Reported protein intake represented 16.9% of total energy intake (range 10%–25%). For several nutrients, including vitamin D and calcium, intake from food and supplements in many participants exceeded recommended Tolerable Upper Intake Levels. Among adults with cystic fibrosis, vitamin D deficiency was common despite reported adequate intake, and lipid profiles were normal despite a relatively high fat intake. Mean protein consumption was adequate, but the range of intake was concerning, as both inadequate or excessive intake may have deleterious skeletal effects. These findings call into question the applicability of established nutrient thresholds for patients with cystic fibrosis. PMID:18060897

Nutrient timing revisited: is there a post-exercise anabolic window?

Directory of Open Access Journals (Sweden)

Aragon Alan Albert

2013-01-01

Full Text Available Abstract Nutrient timing is a popular nutritional strategy that involves the consumption of combinations of nutrients--primarily protein and carbohydrate--in and around an exercise session. Some have claimed that this approach can produce dramatic improvements in body composition. It has even been postulated that the timing of nutritional consumption may be more important than the absolute daily intake of nutrients. The post-exercise period is widely considered the most critical part of nutrient timing. Theoretically, consuming the proper ratio of nutrients during this time not only initiates the rebuilding of damaged muscle tissue and restoration of energy reserves, but it does so in a supercompensated fashion that enhances both body composition and exercise performance. Several researchers have made reference to an anabolic “window of opportunity” whereby a limited time exists after training to optimize training-related muscular adaptations. However, the importance - and even the existence - of a post-exercise ‘window’ can vary according to a number of factors. Not only is nutrient timing research open to question in terms of applicability, but recent evidence has directly challenged the classical view of the relevance of post-exercise nutritional intake with respect to anabolism. Therefore, the purpose of this paper will be twofold: 1 to review the existing literature on the effects of nutrient timing with respect to post-exercise muscular adaptations, and; 2 to draw relevant conclusions that allow practical, evidence-based nutritional recommendations to be made for maximizing the anabolic response to exercise.

Jang, Jiin-Yuh; Huang, Jun-Bo

2015-01-01

A two-dimensional mathematical heat transfer model for the prediction of the temperature history of steel slabs was performed in order to obtain the optimal heating pattern of these slabs with minimum energy consumption in a walking-beam type reheating furnace. An algorithm developed with a simplified conjugated-gradient method combined with a shooting method, was used as an optimizer to design the furnace temperature distribution, including the preheating zone, heating zone and soaking zone temperatures. Comparison with the in-situ experimental data indicated that the present heat transfer model works well for the prediction of the thermal behavior of a slab in the reheating furnace. The effect of the furnace temperature distribution on the design requirements, such as energy required for heating a slab, slab temperature uniformity at the furnace exit and slab discharging temperature, were investigated. The parametric study results indicated that energy consumption significantly decreases with reductions in the preheating zone temperature. The optimal design also resulted in lower energy consumption for heating a slab as compared to the original operational conditions in the steel plant. - Highlights: • The heating process of steel slabs in a reheating furnace is numerically simulated. • An algorithm is developed to search for the optimal heating pattern of a slab. • Energy consumption decreases with reductions in the preheating zone temperature

The advertising and marketing of energy-dense, nutrient-poor (EDNP) food and drink has been cited as one contributor to unhealthy eating behaviors in adolescents. The present study examines perceptions about and trust in food advertising and their association with consumption of EDNP foods and drinks among adolescents in the United States. Data (n = 1,384) come from the U.S. National Cancer Institute's Family Life, Activity, Sun, Health, and Eating Survey. One way ANOVAs were conducted to assess differences between population subgroups in advertising perceptions. Bivariate and multivariable linear regression models were used to examine the associations between perceptions toward and trust in food advertising and consumption of EDNP foods and drinks, controlling for sociodemographic factors. Results show that there are significant differences between racial/ethnic groups on advertising perceptions (F = 16.32, p = advertising increase among adolescents, there is an associated increase in daily frequency of consumption of EDNP foods and drinks (β = 0.10, p advertising, the higher the reported daily frequency of EDNP food and drink consumption (β = 0.08, p = .01). Targeting perceptions about food advertising may be a worthy intervention strategy to reduce the impact of food marketing and the consumption of heavily advertised EDNP foods and drinks among adolescents.

A comprehensive study of spatial and temporal consumption patterns of the selected illicit drugs (heroin, cocaine, amphetamine, MDMA, methamphetamine, cannabis) and therapeutic opioids (codeine, methadone) has been performed in six Croatian cities by applying wastewater-based epidemiology. The investigated cities (Bjelovar, Vinkovci, Varazdin, Karlovac, Zadar and Zagreb) varied widely in the population size (27,000-688,000 inhabitants) as well as in the number of registered drug consumers included in compulsory and voluntary medical treatment and rehabilitation programs (30-513 persons/100,000 inhabitants of age 15-64). The most consumed illicit drugs were cannabis (10-70doses/day/1000 inhabitants), heroin (consumption of amphetamine-type drugs was much lower (consumption of illegal drugs was generally associated with larger urban centers (Zagreb and Zadar) however comparatively high consumption rate of cocaine, MDMA and methadone was determined in some smaller cities as well. The overall average dose number of 3 major illegal stimulants (cocaine, MDMA, amphetamine) was rather similar to the number of corresponding heroin doses, which is in disagreement with a comparatively much higher proportion of heroin users in the total number of registered drug users in Croatia. Furthermore, the illicit drug consumption pattern in the large continental city (Zagreb) was characterized by a significant enhancement of the consumption of all stimulants during the weekend, which could not be confirmed neither for the coastal city of Zadar nor for the remaining small continental cities. On the other hand, the city of Zadar exhibited a significant increase of stimulant drug usage during summer vacation period, as a result of pronounced seasonal changes of the population composition and lifestyle in coastal tourist centers. The obtained results represent a valuable complementary data source for the optimisation and implementation of strategies to combat drug abuse in Croatia

Full Text Available The study of inorganic nutrients dynamics in shallow sediments usually focuses on two main pools: the porewater (PW nutrients and the exchangeable (EX ammonium and phosphate. Recently, it has been found that microphytobenthos (MPB and other microorganisms can accumulate large amounts of nutrients intracellularly (IC, highlighting the biogeochemical importance of this nutrient pool. Storing nutrients could support the growth of autotrophs when nutrients are not available, and could also provide alternative electron acceptors for dissimilatory processes such as nitrate reduction. Here, we studied the magnitude and relative importance of these three nutrient pools (PW, IC and EX and their relation to chlorophylls (used as a proxy for MPB abundance and organic matter (OM contents in an intertidal mudflat of Cadiz Bay (Spain. MPB was localized in the first 4 mm of the sediment and showed a clear seasonal pattern; highest chlorophylls content was found during autumn and lowest during spring-summer. The temporal and spatial distribution of nutrients pools and MPB were largely correlated. Ammonium was higher in the IC and EX fractions, representing on average 59 and 37% of the total ammonium pool, respectively. Similarly, phosphate in the IC and EX fractions accounted on average for 40 and 31% of the total phosphate pool, respectively. Nitrate in the PW was low, suggesting low nitrification activity and rapid consumption. Nitrate accumulated in the IC pool during periods of moderate MPB abundance, being up to 66% of the total nitrate pool, whereas it decreased when chlorophyll concentration peaked likely due to a high nitrogen demand. EX-Nitrate accounted for the largest fraction of total sediment nitrate, 66% on average. The distribution of EX-Nitrate was significantly correlated with chlorophyll and OM, which probably indicates a relation of this pool to an increased availability of sites for ionic adsorption. This EX-Nitrate pool could represent an

Effect of hypoxia on benthic nutrient fluxes in the northwestern Black Sea

Friedrich, J.

2012-04-01

The western Black Sea shelf has been affected by eutrophication from the 1960s to the mid 1990s. A combination of increased nutrient loads from the major inflowing rivers Danube, Dniester and Dnepr and favourable climate conditions led to high productivity regimes. As a consequence, increased oxygen consumption due to decomposition of organic matter caused recurrent seasonal bottom water hypoxia for more than 20 years. In addition, recycling of nutrients from organic matter settling to the seafloor along with tight benthic-pelagic coupling represents an important internal source for productivity, hence internally supporting eutrophication. From the 1970s to 1990s, the benthic and pelagic systems deteriorated and ecosystem structure and functioning changed. Following the collapse of the centrally planned economies in the eastern European countries during the 1990s, the riverine nutrient input decreased, and the ecosystem, now slowly responding, shows signs of recovery; e.g. by a decrease in hypoxic events. In this study, benthic nutrient flux data from in-situ and ex-situ experiments during the 1990s on the Danube-influenced north-western Black Sea shelf and data from the 2000s, including the EU-FP7 HYPOX experiments, are analysed to reveal the effect of hypoxia on benthic nutrient fluxes. Mann-Whitney statistical tests have been applied to demonstrate the significance of differences in fluxes due to varying oxygen conditions in the water. During the 1990s experiments, bottom water hypoxia was encountered in all locations, while during the 2000s hypoxia has been met only during summer in the Danube Prodelta area and near the Dniester mouth. Indeed, bottom water oxygen in the 1990s has been statistically significantly lower than in the 2000s while benthic oxygen consumption was higher during eutrophication-induced hypoxia. The benthic nutrient fluxes in the 1990s and the 2000s however do not differ significantly. During hypoxia, despite ceasing eutrophication

AIM: This study aimed at assessing prevailing patterns and risk factors of tobacco consumption among clients, food handlers and employers of food facilities, in Riyadh, Saudi Arabia. METHODS: A cross-sectional approach to a representative sample of food facilities in Riyadh was used. A sample of 3000 participants included clients (75%); food handlers/hospitality workers (20 %) and employers (5 %). Participants were reached at restaurants, food courts or cafes. A modified version of the WHO-CDC-Global Youth Tobacco Survey questionnaire was used for data collection. RESULTS: The prevalence of tobacco use at food facilities was found to be 40.3 %, of which 74% were customers, 18.8% were food handlers and 7.2% were managers. The consumption of tobacco was higher at restaurants (39.9%), but lowest at food courts of shopping malls. Water pipe (55.3%) was the main consumption type, followed by cigarettes (42.6%) and chewing tobacco (2.1%). Multivariate analysis showed that gender (male), marital status (single), and type of food facility (Estaraha and café/coffee shop) were independent risk factors associated with tobacco use at food facilities. CONCLUSION: Tobacco use is very common in food facilities in Riyadh as reflected by results of our study, especially among single males Saudis. We should build on success encountered in banning smoking in airports, airplanes, shopping malls, market places, educational institutions and healthcare facilities, extending the ban to include food facilities as well. This is important for the health of non-smokers as well as smokers themselves. PMID:24987478

Foliar Nutrient Distribution Patterns in Sympatric Maple Species Reflect Contrasting Sensitivity to Excess Manganese.

Fernando, Denise R; Marshall, Alan T; Lynch, Jonathan P

2016-01-01

Sugar maple and red maple are closely-related co-occurring tree species significant to the North American forest biome. Plant abiotic stress effects including nutritional imbalance and manganese (Mn) toxicity are well documented within this system, and are implicated in enhanced susceptibility to biotic stresses such as insect attack. Both tree species are known to overaccumulate foliar manganese (Mn) when growing on unbuffered acidified soils, however, sugar maple is Mn-sensitive, while red maple is not. Currently there is no knowledge about the cellular sequestration of Mn and other nutrients in these two species. Here, electron-probe x-ray microanalysis was employed to examine cellular and sub-cellular deposition of excessively accumulated foliar Mn and other mineral nutrients in vivo. For both species, excess foliar Mn was deposited in symplastic cellular compartments. There were striking between-species differences in Mn, magnesium (Mg), sulphur (S) and calcium (Ca) distribution patterns. Unusually, Mn was highly co-localised with Mg in mesophyll cells of red maple only. The known sensitivity of sugar maple to excess Mn is likely linked to Mg deficiency in the leaf mesophyll. There was strong evidence that Mn toxicity in sugar maple is primarily a symplastic process. For each species, leaf-surface damage due to biotic stress including insect herbivory was compared between sites with acidified and non-acidified soils. Although it was greatest overall in red maple, there was no difference in biotic stress damage to red maple leaves between acidified and non-acidified soils. Sugar maple trees on buffered non-acidified soil were less damaged by biotic stress compared to those on unbuffered acidified soil, where they are also affected by Mn toxicity abiotic stress. This study concluded that foliar nutrient distribution in symplastic compartments is a determinant of Mn sensitivity, and that Mn stress hinders plant resistance to biotic stress.

To examine patterns of adolescent sports and energy drink (SED) consumption and identify behavioral correlates. Data were drawn from Eating and Activity in Teens, a population-based study. Adolescents from 20 middle and high schools in Minneapolis/St Paul, MN completed classroom-administered surveys. A total of 2,793 adolescents (53.2% girls) in grades 6-12. Beverage patterns; breakfast frequency; moderate to vigorous physical activity (MVPA); media use; sleep; and cigarette smoking. Linear and logistic regression models were used to estimate associations between health behaviors and SED consumption, adjusting for demographics. Over a third of adolescents consumed sports drinks and 14.7% consumed energy drinks at least once a week. Among boys and girls, both sports and energy drink consumption were related to higher video game use; sugar-sweetened beverage and fruit juice intake; and smoking (P Sports drink consumption was also significantly related to higher MVPA and organized sport participation for both genders (P sports drink consumption was associated with higher MVPA, adolescents should be reminded of recommendations to consume these beverages only after vigorous, prolonged activity. There is also a need for future interventions designed to reduce SED consumption, to address the clustering of unhealthy behaviors. Copyright © 2014 Society for Nutrition Education and Behavior.

2017-01-01

Full Text Available Electricity demand forecasting is of important role in power system planning and operation. In this work, fuzzy nearest neighbour regression has been utilised to estimate monthly electricity demands. The forecasting model was based on the pre-processed energy consumption time series, where input and output variables were defined as patterns representing unified fragments of the time series. Relationships between inputs and outputs, which were simplified due to patterns, were modelled using nonparametric regression with weighting function defined as a fuzzy membership of learning points to the neighbourhood of a query point. In an experimental part of the work the model was evaluated using real-world data. The results are encouraging and show high performances of the model and its competitiveness compared to other forecasting models.

Full Text Available Trademarks are highly valuable devices that serve a relevant purpose in trade and consumption patterns. However, trademarks have been largely neglected by Argentina's economic history historiography. This article discusses how and when trademarks emerged and spread in Argentina's rural area in the early 20th century. It describes this gradual process, pointing out that, by the late 1920s, trademarks had already become a prominent feature in rural marketing strategies and consumption patterns. The study also analyzes how these processes contributed to shaping retailers' business practices as well as generic consumer goods' marketing channels (particularly, in the food and beverage industries

Full Text Available Abstract Background Little is known about the consumption of organic food during pregnancy. The aim of this study was to describe dietary characteristics associated with frequent consumption of organic food among pregnant women participating in the Norwegian Mother and Child Cohort Study (MoBa. Methods The present study includes 63 808 women who during the years 2002–2007 answered two questionnaires, a general health questionnaire at gestational weeks 15 and a food frequency questionnaire at weeks 17-22. The exploration of food patterns by Principal component analyses (PCA was followed by ANOVA analyses investigating how these food patterns as well as intake of selected food groups were associated with consumption of organic food. Results The first principal component (PC1 identified by PCA, accounting for 12% of the variation, was interpreted as a ‘health and sustainability component’, with high positive loadings for vegetables, fruit and berries, cooking oil, whole grain bread and cereal products and negative loadings for meat, including processed meat, white bread, and cakes and sweets. Frequent consumption of organic food, which was reported among 9.1% of participants (n = 5786, was associated with increased scores on the ‘health and sustainability component’ (p  Conclusion The present study showed that pregnant Norwegian women reporting frequent consumption of organically produced food had dietary pattern and quality more in line with public advice for healthy and sustainable diets. A methodological implication is that the overall diet needs to be included in future studies of potential health outcomes related to consumption of organic food during pregnancy.

Dietary patterns are useful in nutritional epidemiology, providing a comprehensive alternative to the traditional approach based on single nutrients. The Cardiovascular Risk in Young Finns Study is a prospective cohort study with a 21-year follow-up. At baseline, detailed quantitative information on subjects' food consumption was obtained using a 48 h dietary recall method (n 1768, aged 3-18 years). The interviews were repeated after 6 and 21 years (n 1200 and n 1037, respectively). We conducted a principal component analysis to identify major dietary patterns at each study point. A set of two similar patterns was recognised throughout the study. Pattern 1 was positively correlated with consumption of traditional Finnish foods, such as rye, potatoes, milk, butter, sausages and coffee, and negatively correlated with fruit, berries and dairy products other than milk. Pattern 1 type of diet was more common among male subjects, smokers and those living in rural areas. Pattern 2, predominant among female subjects, non-smokers and in urban areas, was characterised by more health-conscious food choices such as vegetables, legumes and nuts, tea, rye, cheese and other dairy products, and also by consumption of alcoholic beverages. Tracking of the pattern scores was observed, particularly among subjects who were adolescents at baseline. Of those originally belonging to the uppermost quintile of pattern 1 and 2 scores, 41 and 38 % respectively, persisted in the same quintile 21 years later. Our results suggest that food behaviour and concrete food choices are established already in childhood or adolescence and may significantly track into adulthood.

Dominance of free-floating plants poses a threat to biodiversity in many freshwater ecosystems. Here we propose a theoretical framework to understand this dominance, by modeling the competition for light and nutrients in a layered community of floating and submerged plants. The model shows that at high supply of light and nutrients, floating plants always dominate due to their primacy for light, even when submerged plants have lower minimal resource requirements. The model also shows that floating-plant dominance cannot be an alternative stable state in light-limited environments but only in nutrient-limited environments, depending on the plants' resource consumption traits. Compared to unlayered communities, the asymmetry in competition for light-coincident with symmetry in competition for nutrients-leads to fundamentally different results: competition outcomes can no longer be predicted from species traits such as minimal resource requirements ([Formula: see text] rule) and resource consumption. Also, the same two species can, depending on the environment, coexist or be alternative stable states. When applied to two common plant species in temperate regions, both the model and field data suggest that floating-plant dominance is unlikely to be an alternative stable state.

The purpose of this study was to compare nutrients and energy intakes between obese women and men and the variation rates over or below the recommended dietary allowances. A retrospective survey was conducted on the records of obese patients, categorized into gender-related groups (36 women, 36 men). Total energy and nutrient intakes were determined. The highest variation rates were found for animal protein, averaging 225 % over the recommended dietary allowance, without significant differences between women and men. The simple carbohydrate intake was quite elevated in women with variations almost 80% over the RDA, significantly higher than in men (22%). The consumption of high-protein foods in both sexes, and even more the association with high-simple carbohydrate foods in women, display the Westernization of traditional eating habits.

Associations between individual foods and nutrients and colorectal cancer have been inconsistent, and few studies have examined associations between food, nutrients, dietary patterns, and rectal cancer. We examined the relationship between food groups and dietary patterns and risk for rectal cancer in non-Hispanic Whites and African-Americans. Data were from the North Carolina Colon Cancer Study-Phase II and included 1,520 Whites (720 cases, 800 controls) and 384 African-Americans (225 cases, 159 controls). Diet was assessed using the Diet History Questionnaire. Multivariate logistic regression models were used to estimate odds ratios and 95% confidence intervals. Among Whites, non-whole grains and white potatoes were associated with elevated risk for rectal cancer whereas fruit, vegetables, dairy, fish, and poultry were associated with reduced risk. In African-Americans, high consumption of other fruit and added sugar suggested elevated risk. We identified three major dietary patterns in Whites and African-Americans. The high fat/meat/potatoes pattern was observed in both race groups but was only positively associated with risk in Whites (odds ratio, 1.84; 95% confidence interval, 1.03-3.15). The vegetable/fish/poultry and fruit/whole grain/dairy patterns in Whites had significant inverse associations with risk. In African-Americans, there was a positive dose-response for the fruit/vegetables pattern (P(trend) pattern (P(trend) dietary patterns with rectal cancer risk differ between Whites and African-Americans, highlighting the importance of examining diet and cancer relationships in racially diverse populations.

The adjustment of feeding behavior in response to hunger and satiety contributes to homeostatic regulation in animals. The fruit fly Drosophila melanogaster feeds on yeasts growing on overripe fruit, providing nutrients required for adult survival, reproduction and larval growth. Here, we present data on how the nutritional value of food affects subsequent yeast consumption in Drosophila adult males. After a period of starvation, flies showed intensive yeast consumption. In comparison, flies stopped feeding after having access to a nutritive cornmeal diet. Interestingly, dietary glucose was equally efficient as the complex cornmeal diet. In contrast, flies fed with sucralose, a non-metabolizable sweetener, behaved as if they were starved. The adipokinetic hormone and insulin-like peptides regulate metabolic processes in insects. We did not find any effect of the adipokinetic hormone pathway on this modulation. Instead, the insulin pathway was involved in these changes. Flies lacking the insulin receptor (InR) did not respond to nutrient deprivation by increasing yeast consumption. Together these results show the importance of insulin in the regulation of yeast consumption in response to starvation in adult D. melanogaster males.

Ultra-Processed Food Consumption and Chronic Non-Communicable Diseases-Related Dietary Nutrient Profile in the UK (2008⁻2014).

We described the contribution of ultra-processed foods in the U.K. diet and its association with the overall dietary content of nutrients known to affect the risk of chronic non-communicable diseases (NCDs). Cross-sectional data from the U.K. National Diet and Nutrition Survey (2008⁻2014) were analysed. Food items collected using a four-day food diary were classified according to the NOVA system. The average energy intake was 1764 kcal/day, with 30.1% of calories coming from unprocessed or minimally processed foods, 4.2% from culinary ingredients, 8.8% from processed foods, and 56.8% from ultra-processed foods. As the ultra-processed food consumption increased, the dietary content of carbohydrates, free sugars, total fats, saturated fats, and sodium increased significantly while the content of protein, fibre, and potassium decreased. Increased ultra-processed food consumption had a remarkable effect on average content of free sugars, which increased from 9.9% to 15.4% of total energy from the first to the last quintile. The prevalence of people exceeding the upper limits recommended for free sugars and sodium increased by 85% and 55%, respectively, from the lowest to the highest ultra-processed food quintile. Decreasing the dietary share of ultra-processed foods may substantially improve the nutritional quality of diets and contribute to the prevention of diet-related NCDs.

Research strategies and the use of nutrient biomarkers in studies of diet and chronic disease.

To provide an account of the state of diet and chronic disease research designs and methods; to discuss the role and potential of aggregate and analytical observational studies and randomised controlled intervention trials; and to propose strategies for strengthening each type of study, with particular emphasis on the use of nutrient biomarkers in cohort study settings. Observations from diet and disease studies conducted over the past 25 years are used to identify the strengths and weaknesses of various study designs that have been used to associate nutrient consumption with chronic disease risk. It is argued that a varied research programme, employing multiple study designs, is needed in response to the widely different biases and constraints that attend aggregate and analytical epidemiological studies and controlled intervention trials. Study design modifications are considered that may be able to enhance the reliability of aggregate and analytical nutritional epidemiological studies. Specifically, the potential of nutrient biomarker measurements that provide an objective assessment of nutrient consumption to enhance analytical study reliability is emphasised. A statistical model for combining nutrient biomarker data with self-report nutrient consumption estimates is described, and related ongoing work on odds ratio parameter estimation is outlined briefly. Finally, a recently completed nutritional biomarker study among 102 postmenopausal women in Seattle is mentioned. The statistical model will be applied to biomarker data on energy expenditure, urinary nitrogen, selected blood fatty acid measurements and various blood micronutrient concentrations, and food frequency self-report data, to identify study subject characteristics, such as body mass, age or socio-economic status, that may be associated with the measurement properties of food frequency nutrient consumption estimates. This information will be crucial for the design of a potential larger nutrient

Modeling nutrient in-stream processes at the watershed scale using Nutrient Spiralling metrics

One of the fundamental problems of using large-scale biogeochemical models is the uncertainty involved in aggregating the components of fine-scale deterministic models in watershed applications, and in extrapolating the results of field-scale measurements to larger spatial scales. Although spatial or temporal lumping may reduce the problem, information obtained during fine-scale research may not apply to lumped categories. Thus, the use of knowledge gained through fine-scale studies to predict coarse-scale phenomena is not straightforward. In this study, we used the nutrient uptake metrics defined in the Nutrient Spiralling concept to formulate the equations governing total phosphorus in-stream fate in a deterministic, watershed-scale biogeochemical model. Once the model was calibrated, fitted phosphorus retention metrics where put in context of global patterns of phosphorus retention variability. For this purpose, we calculated power regressions between phosphorus retention metrics, streamflow, and phosphorus concentration in water using published data from 66 streams worldwide, including both pristine and nutrient enriched streams. Performance of the calibrated model confirmed that the Nutrient Spiralling formulation is a convenient simplification of the biogeochemical transformations involved in total phosphorus in-stream fate. Thus, this approach may be helpful even for customary deterministic applications working at short time steps. The calibrated phosphorus retention metrics were comparable to field estimates from the study watershed, and showed high coherence with global patterns of retention metrics from streams of the world. In this sense, the fitted phosphorus retention metrics were similar to field values measured in other nutrient enriched streams. Analysis of the bibliographical data supports the view that nutrient enriched streams have lower phosphorus retention efficiency than pristine streams, and that this efficiency loss is maintained in a wide

Food and animal characteristics relevant to the prediction of forage consumption and nutrient use in productive ruminants

A general model is presented of the relationships between animal and food characteristics which help lead to predictions of food consumption and animal performance. It is an important part of this scheme that equal weight is given to the description of food and animal characteristics. The results of some experiments are given suggesting that ruminants can select between feeds to meet their nutrient needs and that, in growing animals, the physical capacity to bite is an important determinant of grazing efficiency and ecology. Studies with growing lambs of the energetic efficiency of growth suggest that variation in the energy cost of protein accretion may be a more important determinant of overall energetic efficiency of growth than is conventionally supposed. In lactating animals that also exercise, milk protein and lactose yields fall during exercise and this effect is difficult to counteract by protein and/or starch supplementation of straw diets. Studies of forage substitution by supplements have not revealed differences in substitution rate with age in sheep. (author). 22 refs, 6 figs, 2 tabs

Character Apps for Children's Snacks: Effects of Character Awareness on Snack Selection and Consumption Patterns.

Putnam, Marisa M; Cotto, Caroline E; Calvert, Sandra L

2018-04-01

Media characters are used to market snacks that are typically of poor nutritional value, which has been linked to childhood obesity. This study examines whether children's snack selections and consumption patterns are influenced by an app depicting a popular children's media character, as well as the role that children's awareness of the character plays. The results can increase our understanding of how to encourage healthier snack selection and consumption in newer game-based marketing venues, such as apps. Four- and 5-year-old children (N = 132) played a bowling game on an iPad with no character or with a character holding either healthier or unhealthy snacks. After app-play, children selected and consumed healthier or unhealthy snacks. Children's awareness of the character was measured by children's verbalizations of the character's name during or after app-play. An ordered logistic regression found no significant effect of treatment conditions compared with the control group. Within treatment conditions, awareness of the character led to selection and consumption of more healthy snacks in the healthier condition (odds ratio β = 10.340, P = 0.008), and of unhealthy snacks in the unhealthy condition (odds ratio β = 0.228, P = 0.033), but children were unaware that the character influenced their decisions. Results suggest that young children will choose and consume healthier, not just unhealthy, products when they are aware that a popular character in an app is associated with the snack, potentially leading to healthier eating patterns.

1991-12-01

As part of the Euronut SENECA study, food consumption has been assessed in 1217 men and 1241 women, born between 1913 and 1918 and living in 18 towns in 12 European countries. The method used was a standardized modified dietary history, including a 3-day estimated record and a food frequency list based on local food patterns. Intakes of energy, protein, fat, carbohydrate, fatty acids, cholesterol and alcohol are described in this paper. As expected, a difference between men and women in energy and nutrient intake was observed in all towns. There was a great variation between towns in mean dietary intakes of all dietary components. Mean energy intake of men ranged from 12.7 MJ in Marki (Poland) to 8.2 MJ in Yverdon (Switzerland) and Chateau Renault-Amboise (France). For women the range was from 10.9 MJ in Marki (Poland) to 6.3 MJ in Yverdon (Switzerland) and Vila Franca de Xira (Portugal). A geographical pattern can be detected for the intake of fatty acids. Intakes of saturated fat were lower in southern than in northern European towns. The calculated ratio for intakes of unsaturated and saturated fatty acids (polyunsaturated fatty acids plus monounsaturated fatty acids/saturated fatty acids) for all participants was higher in the southern European centres than in the northern centres and ranged from 2.7 in Markopoulo (Greece) to 1.2 in Elverum (Norway) and Marki (Poland). Alcohol consumption was considerable higher in men than in women. In men a north-south gradient in alcohol intake can be detected, with the highest intake in the two centres in Italy, where, on average 11% of energy intake was derived from alcohol.

Energy Consumption of Lactating Mothers: Current Situation and Problems

Directory of Open Access Journals (Sweden)

Sandra Fikawati

2014-08-01

Full Text Available Recommendations on the adequacy of nutrient intake indicate that lactating mothers have higher nutritional needs than do pregnant mothers. High nutrient intake is necessary to help mothers recover after childbirth, produce milk, and maintain the quantity and quality of breast milk. It also prevents maternal malnutrition. Research has shown, however, that the dietary energy consumption of mothers during lactation was significantly lower than that during pregnancy. The current study explored the factors associated with decreased nutritional intake during maternal lactation. The study was conducted in March–April 2013, and the subjects were mothers with infants aged >6 months. Results revealed that the factors causing low dietary energy consumption among breastfeeding mothers were poor nutritional knowledge and attitude toward high energy intake requirements during lactation, lack of time to cook and eat because of infant care, reduced consumption of milk and supplements, dietary restrictions and prohibitions, and suboptimal advice from midwives/health personnel. Beginning from the antenatal care visit, health personnel should conduct effective counseling on the importance of nutrient intake during lactation.

The intention of this chapter is to explore the role of consumption and consumers in relation to sustainability transition processes and wider systemic transformations. In contrast to the individualistic focus in much research on sustainable consumption, the embeddedness of consumption activities...... in wider social, economic and technological frameworks is emphasised. In particular, the chapter is inspired by practice theory and transition theory. First, various trends in consumption are outlined to highlight some of the challenges for sustainability transitions. Then, it is discussed how consumption...... patterns are shaped over time and what should be considered in sustainability strategies. While discussions on consumption often take their point of departure in the perspective of the individual and then zoom to the wider context, the present approach is the opposite. The outline starts with the basic...

The present study investigated the perceived health benefits of specific vegetable consumption to guide the use of nutrition and health claims on vegetable marketing collateral. Free elicitation and consumer ranking data were collected through an online survey of 1000 adults from across Australia and analysed for the perceived importance of vegetables in the daily diet, number of serves consumed per day, knowledge about health-related benefits of specific vegetables and perceived health benefits of vegetable consumption. The importance of vegetables in the diet and daily vegetable consumption was higher in people from an English-speaking background, females, people aged 45 years and over and people living in non-metropolitan areas. Digestion was selected as the major health benefit from consumption of specific vegetables. However, understanding of the health benefits of specific vegetable consumption was relatively low among consumers. Half of the respondents were not sure of the health benefits associated with specific vegetables, except for carrots and spinach. Some respondents volunteered nutrient content or other information. There was no clear indication that consumers understand the specific health benefits conferred by consumption of vegetables. Nutrient and health benefit labelling therefore has the capacity to enhance knowledge of vegetable consumers. It is recommended that health benefit labelling be tailored to promote greater consumption of vegetables in those demographic groups where vegetable consumption was lower. The present study assists the Australian vegetable industry in helping consumers make more informed consumption choices. © 2016 Dietitians Association of Australia.

Reducing the consumption of meat and other animal-based products is widely advocated to improve the sustainability of diets in high-income countries. However, such reduction may impair nutritional adequacy, since the bioavailability of key nutrients is higher when they come from animal- vs plant-based foods. Meat reduction may also affect the balance between foods co-produced within the same animal production system. The objective was to assess the impact of introducing nutrient bioavailability and co-production links considerations on the dietary changes needed - especially regarding meat ‒ to improve diet sustainability. Diet optimization with linear and non-linear programming was used to design, for each gender, three modeled diets departing the least from the mean observed French diet (OBS) while reducing by at least 30% the diet-related environmental impacts (greenhouse gas emissions, eutrophication, acidification): i) in the nutrition-environment (NE) model, the fulfillment of recommended dietary allowances for all nutrients was imposed; ii) in the NE-bioavailability (NEB) model, nutritional adequacy was further ensured by accounting for iron, zinc, protein and provitamin A bioavailability; iii) in the NEB-co-production (NEB-CP) model, two links between co-produced animal foods (milk-beef and blood sausage-pork) were additionally included into the models by proportionally co-constraining their respective quantities. The price and environmental impacts of individual foods were assumed to be constant. 'Fruit and vegetables' and 'Starches' quantities increased in all modeled diets compared to OBS. In parallel, total meat and ruminant meat quantities decreased. Starting from 110g/d women's OBS diet (168g/d for men), total meat quantity decreased by 78%, 67% and 32% for women (68%, 66% and 62% for men) in NE, NEB and NEB-CP diets, respectively.

Seasonal cycles of pelagic production and consumption

Science.gov (United States)

Longhurst, Alan

Comprehensive seasonal cycles of production and consumption in the pelagial require the ocean to be partitioned. This can be done rationally at two levels: into four primary ecological domains (three oceanic and one coastal), or about fifty biogeochemical provinces. The domains differ in their characteristic seasonal cycles of stability, nutrient supply and illumination, while provinces are defined by ocean currents, fronts, topography and recurrent features in the sea surface chlorophyll field. For each of these compartments, seasonal cycles of photic depth, primary production and accumulation (or loss) of algal biomass were obtained from the climatological CZCS chlorophyll field and other data and these, together with mixed layer depths, rendered characteristic seasonal cycles of production and consumption, which can be grouped into eight models: i - polar irradiance-mediated production peak; ii - nutrient-limited spring production peak; iii - winter-spring production with nutrient limitation; iv - small amplitude response to trade wind seasonality; v - large amplitude response to monsoon reversal; vi - canonical spring-fall blooms of mid-latitude continental shelves; vii - topography-forced summer production; viii - intermittent production at coastal divergences. For higher latitudes, these models suggest that the observed late-summer ‘blooms’ result not from a renewal of primary production rate, but from a relaxation of grazing pressure; in mid-latitudes, the observed ‘winter’ bloom represents chlorophyll accumulation at a season when loss terms are apparently smaller than during the period of peak primary production rate which occurs later, in spring. Where an episodic seasonal increase in rate of primary production occurs, as in the Arabian Sea, algal biomass accumulation may brief, lasting only until consumption is fully re-established. Only in the low latitude oligotrophic ocean are production and consumption perennially and closely coupled.

Consumption Over Life Cycle: How Different is Housing?

Micro data over the life cycle shows different patterns of consumption for housing and non-housing goods: the consumption profile of non-housing goods is hump-shaped while the consumption profile for housing first increases monotonically and then flattens out. These patterns hold true at each consumption quartile. This paper develops aquantitative, dynamic general equilibrium model of life-cycle behavior, which generates consumption profiles consistent with the observed data. Borrowing constr...

. Soil shear resistance was highest on finer textured soil with the highest watering treatment, whereas compression resistance was highest on the coarsest textured soils with the highest watering amounts. Nutrient addition did not influence total cover or biocrust function, but did decrease lichen cover. Taken together, these results suggest that interactions between soil texture, water, and to a lesser degree nutrients, create predictable patterns in biocrust assemblage and offers a mechanistic understanding of edaphic controls over biocrust abundance and structure. These insights add to our increasing understanding of how edaphic gradients structure soil communities.

Education frequently dictates students need to study for prolonged periods of time to adequately prepare for examinations. This is especially true with aviation preflight indoctrination (API) candidates who have to assimilate large volumes of information in a limited amount of time during API training. The purpose of this study was to assess caffeine consumption patterns (frequency, type, and volume) among naval aviation candidates attending API to determine the most frequently consumed caffeinated beverage and to examine if the consumption of a nonenergy drink caffeinated beverage was related to energy drink consumption. Data were collected by means of an anonymous 44-item survey administered and completed by 302 students enrolled in API at Naval Air Station Pensacola, FL. Results indicated the most frequently consumed caffeinated beverage consumed by API students was coffee (86.4%), with daily coffee consumption being approximately 28% and the most frequent pattern of consumption being 2 cups per day (85%). The least frequently consumed caffeinated beverages reported were energy drinks (52%) and energy shots (29.1%). The present study also found that the consumption patterns (weekly and daily) of caffeinated beverages (coffee and cola) were positively correlated to energy drink consumption patterns. Naval aviation candidates' consumption of caffeinated beverages is comparable to other college and high school cohorts. This study found that coffee and colas were the beverages of choice, with energy drinks and energy shots being the least frequently reported caffeinated beverages used. Additionally, a relationship between the consumption of caffeinated beverages and energy drinks was identified.Sather TE, Williams RD, Delorey DR, Woolsey CL.

Long-lived animals, including social insects, often display seasonal shifts in foraging behavior. Foraging is ultimately a nutrient consumption exercise, but the effect of seasonality per se on changes in foraging behavior, particularly as it relates to nutrient regulation, is poorly understood. Here, we show that field-collected fire ant colonies, returned to the laboratory and maintained under identical photoperiod, temperature, and humidity regimes, and presented with experimental foods that had different protein (p) to carbohydrate (c) ratios, practice summer- and fall-specific foraging behaviors with respect to protein-carbohydrate regulation. Summer colonies increased the amount of food collected as the p:c ratio of their food became increasingly imbalanced, but fall colonies collected similar amounts of food regardless of the p:c ratio of their food. Choice experiments revealed that feeding was non-random, and that both fall and summer ants preferred carbohydrate-biased food. However, ants rarely ate all the food they collected, and their cached or discarded food always contained little carbohydrate relative to protein. From a nutrient regulation strategy, ants consumed most of the carbohydrate they collected, but regulated protein consumption to a similar level, regardless of season. We suggest that varied seasonal food collection behaviors and nutrient regulation strategies may be an adaptation that allows long-lived animals to meet current and future nutrient demands when nutrient-rich foods are abundant (e.g. spring and summer), and to conserve energy and be metabolically more efficient when nutritionally balanced foods are less abundant.

American Indians, including Navajo, are disproportionately affected by obesity and diabetes, in part due to diet-related health behaviors. The purpose of this study was to assess the patterns of gardening and fruit and vegetable (FV) consumption among residents in two communities on the Navajo Nation in order to inform a community gardening intervention. We analyzed survey data collected from participants in the Yéego Gardening study conducted in two communities in the Navajo Nation (N = 169). We found that 51% of the sample gardened, and on average participants gardened 8.9 times per month. Lack of time (53%) and financial barriers, such as gas for transportation or irrigation (51 and 49%, respectively), were reported as barriers to gardening. Most participants reported low levels of self-efficacy (80%) and behavioral capability (82%) related to gardening. Those with higher levels of gardening self-efficacy and behavioral capability reported more frequent gardening. Average daily FV consumption was 2.5 servings. Most participants reported high levels of self-efficacy to eat FV daily (64%) and high behavioral capability to prepare FV (66%). There was a positive association between FV consumption and gardening, with those gardening more than 4 times per month eating about 1 more serving of FV per day than those gardening 4 or fewer times per month. Further research is needed to better understand how gardening can increase fruit and vegetable availability and consumption among residents of the Navajo Nation.

fractions to analyze the SOC pool dynamics is presented in this study. A detailed field topographic survey and mapping of the spatial variability of soil properties and nutrient contents from soil analyses displayed similar spatial patterns of 137Cs and soil nutrients that also were directly and significantly correlated (p≤0.01). As much as 70% of the surface of the study field had lower values of 137Cs inventory indicating a predominance of soil loss linked to a generalized loss of soil nutrients. SOC gain was found in less than 1% of the study field and there was a large loss of SON compared to the undisturbed reference site. Higher and significant (p≤0.01) contents of soil nutrients were found in topsoil samples than in the bulk ones. Furthermore, there was an enrichment of the relative contribution of ACF to total SOC in sampling points where there was a 137Cs gain in both bulk and topsoil samples. Understanding patterns of soil nutrients can be useful for developing and implementing land management strategies to preserve soil quality in Mediterranean agricultural areas.

Meal pattern analysis can be complex because of the large variability in meal consumption. The use of aggregated, generic meal data may address some of these issues. The objective was to develop a meal coding system and use it to explore meal patterns. Dietary data were used from the National Adult Nutrition Survey (2008-2010), which collected 4-d food diary information from 1500 healthy adults. Self-recorded meal types were listed for each food item. Common food group combinations were identified to generate a number of generic meals for each meal type: breakfast, light meals, main meals, snacks, and beverages. Mean nutritional compositions of the generic meals were determined and substituted into the data set to produce a generic meal data set. Statistical comparisons were performed against the original National Adult Nutrition Survey data. Principal component analysis was carried out by using these generic meals to identify meal patterns. A total of 21,948 individual meals were reduced to 63 generic meals. Good agreement was seen for nutritional comparisons (original compared with generic data sets mean ± SD), such as fat (75.7 ± 29.4 and 71.7 ± 12.9 g, respectively, P = 0.243) and protein (83.3 ± 26.9 and 80.1 ± 13.4 g, respectively, P = 0.525). Similarly, Bland-Altman plots demonstrated good agreement (<5% outside limits of agreement) for many nutrients, including protein, saturated fat, and polyunsaturated fat. Twelve meal types were identified from the principal component analysis ranging in meal-type inclusion/exclusion, varying in energy-dense meals, and differing in the constituents of the meals. A novel meal coding system was developed; dietary intake data were recoded by using generic meal consumption data. Analysis revealed that the generic meal coding system may be appropriate when examining nutrient intakes in the population. Furthermore, such a coding system was shown to be suitable for use in determining meal-based dietary patterns. © 2015

Millennial-scale variability in dust deposition, marine export production, and nutrient consumption in the glacial subantarctic ocean (Invited)

Based on the limitation of modern Southern Ocean phytoplankton by iron and the evidence of higher iron-bearing dust fluxes to the ocean during ice ages, it has been proposed that iron fertilization of Southern Ocean phytoplankton contributed to the reduction in atmospheric CO2 during ice ages. In the Subantarctic zone of the Atlantic Southern Ocean, glacial increases in dust flux and export production have been documented, supporting the iron fertilization hypothesis. However, these observations could be interpreted alternatively as resulting from the equatorward migration of Southern Ocean fronts during ice ages if the observed productivity rise was not accompanied by an increase in major nutrient consumption. Here, new 230Th-normalized lithogenic and opal fluxes are combined with high-resolution biomarker measurements to reconstruct millennial-scale changes in dust deposition and marine export production in the subantarctic Atlantic over the last glacial cycle. In the same record foraminifera-bound nitrogen isotopes are used to reconstruct ice age changes in surface nitrate utilization, providing a comprehensive test of the iron fertilization hypothesis. Elevation in foraminifera-bound δ15N, indicating more complete nitrate consumption, coincides with times of surface cooling and greater dust flux and export production. These observations indicate that the ice age Subantarctic was characterized by iron fertilized phytoplankton growth. The resulting strengthening of the Southern Ocean's biological pump can explain the ~40 ppm lowering of CO2 that characterizes the transitions from mid-climate states to full ice age conditions as well as the millennial-scale atmospheric CO2 fluctuations observed within the last ice age

Dietary glucose regulates yeast consumption in adult Drosophila males

Full Text Available The adjustment of feeding behavior in response to hunger and satiety contributes to homeostatic regulation in animals. The fruit fly Drosophila melanogaster feeds on yeasts growing on overripe fruit, providing nutrients required for adult survival, reproduction and larval growth. Here, we present data on how the nutritional value of food affects subsequent yeast consumption in Drosophila adult males. After a period of starvation, flies showed intensive yeast consumption. In comparison, flies stopped feeding after having access to a nutritive cornmeal diet. Interestingly, dietary glucose was equally efficient as the complex cornmeal diet. In contrast, flies fed with sucralose, a non-metabolizable sweetener, behaved as if they were starved. The adipokinetic hormone and insulin-like peptides regulate metabolic processes in insects. We did not find any effect of the adipokinetic hormone pathway on this modulation. Instead, the insulin pathway was involved in these changes. Flies lacking the insulin receptor did not respond to nutrient deprivation by increasing yeast consumption. Together these results show the importance of insulin in the regulation of yeast consumption in response to starvation in adult D. melanogaster males.

Full Text Available Background and Objective: There are different methods to assess dietary intake in the community. Accurate and appropriate methods, rather than costly and time-consuming ones, are good alternatives to assess dietary intake. The aim of this study was to analyze the validity of telephone and face-to-face interviews, in determination of bread-consumption pattern. Material and Methods: A randomized and stratified multi-stage sampling method was used to select 2312 participating households within the Tehran metropolitan area. The study (research was carried out in two individual and household levels, using 24 hours recall and purchase frequency questionnaire. The same 24 hour recall and purchase frequency questionnaires were used at both individual and household level.Results: At household and individual level, the correlation coefficients between the two methods were 0.64 and 0.60, respectively (p<0.001. Mean difference of intake of bread between the methods at individual level was 16-21 g/day and at household level was 3-4 g/person/day, statistically not significant.Conclusion: Our findings suggest that a telephone survey can provide a reliable estimation of actual bread intake at both individual and household level. This method is important considering its cost and needed time.Keywords: face to face interview, telephone interview, bread consumption pattern

The National School Lunch Program has been guided by modest nutrient standards, and the palatability of meals, which drives consumption, receives inadequate attention. School food waste can have important nutritional and cost implications for policymakers, students, and their families. Nutrient losses and economic costs associated with school meal waste were examined. The study also assessed if school foods served were valid proxies for foods consumed by students. Plate waste measurements were collected from middle school students in Boston attending two Chef Initiative schools (n=1609) and two control schools (n=1440) during a 2-year pilot study (2007-2009) in which a professional chef trained cafeteria staff to make healthier school meals. The costs associated with food waste were calculated and the percentage of foods consumed was compared with a gold standard of 85% consumption. Analyses were conducted in 2010-2011. Overall, students consumed less than the required/recommended levels of nutrients. An estimated $432,349 of food (26.1% of the total food budget) was discarded by middle school students annually at lunch in these Boston middle schools. For most meal components, substantially less than 85% was consumed. There is substantial food waste among middle school students in Boston. Overall, students' nutrient consumption levels were below school meal standards, and foods served were not valid proxies for foods consumed. The costs associated with discarded foods are high; if translated nationally for school lunches, roughly $1,238,846,400 annually is wasted. Students might benefit if additional focus were given to the quality and palatability of school meals. Copyright © 2013 American Journal of Preventive Medicine. Published by Elsevier Inc.

Full Text Available A 36-item Short Diet Questionnaire (SDQ was developed to assess usual consumption frequencies of foods providing fats, fibre, calcium, vitamin D, in addition to fruits and vegetables. It was pretested among 30 community-dwelling participants from the Québec Longitudinal Study on Nutrition and Successful Aging, “NuAge” (n = 1793, 52.4% women, recruited in three age groups (70 ± 2 years; 75 ± 2 years; 80 ± 2 years. Following revision, the SDQ was administered to 527 NuAge participants (55% female, distributed among the three age groups, both sexes and languages (French, English prior to the second of three non-consecutive 24 h diet recalls (24HR and validated relative to the mean of three 24HR. Full data were available for 396 participants. Most SDQ nutrients and fruit and vegetable servings were lower than 24HR estimates (p < 0.05 except calcium, vitamin D, and saturated and trans fats. Spearman correlations between the SDQ and 24HR were modest and significant (p < 0.01, ranging from 0.19 (cholesterol to 0.45 (fruits and vegetables. Cross-classification into quartiles showed 33% of items were jointly classified into identical quartiles of the distribution, 73% into identical and contiguous quartiles, and only 7% were frankly misclassified. The SDQ is a reasonably accurate, rapid approach for ranking usual frequencies of selected nutrients and foods. Further testing is needed in a broader age range.

Full Text Available Dairy nutrients, such as calcium, are particularly important in adolescence, a critical time for growth and development. There are limited Australian data following individuals through adolescence, evaluating changes in dairy nutrient and dairy product consumption. We used a validated food frequency questionnaire to investigate consumption in adolescents participating in both the 14 and 17 year follow-ups of the Western Australian Pregnancy Cohort (Raine Study. Most adolescents did not reach age and gender specific recommended daily intakes for calcium or magnesium at 14 years, and this decreased as they aged to 17 years (from 33.0% to 29.2% meeting for calcium, P < 0.05, and from 33.6% to 20.5% meeting for magnesium, P < 0.01. Mean intakes of calcium, potassium, riboflavin and vitamin A also decreased with age (P < 0.01. Mean dairy intake decreased from 536 ± 343 g/day to 464 ± 339 g/day (P < 0.01, due mostly to a decrease in regular milk, although flavoured milk consumption increased in boys. Cheese and butter were the only products to show a significantly increased consumption over the period. Girls decreased from 2.2 to 1.9 serves/day of dairy, while boys remained relatively steady at 2.9 to 2.8 serves/day. Our findings suggest that dairy product consumption decreases over adolescence. This may have implications for bone mass, development and later health.

Full Text Available Understanding the patterns of wild meat consumption from tropical forests is important for designing approaches to address this major threat to biodiversity and mitigate potential pathways for transmission of emerging diseases. Bushmeat consumption has been particularly poorly studied in Madagascar, one of the world's hottest biodiversity hotspots. Studying bushmeat consumption is challenging as many species are protected and researchers must consider the incentives faced by informants. Using interviews with 1154 households in 12 communes in eastern Madagascar, as well as local monitoring data, we investigated the importance of socio-economic variables, taste preference and traditional taboos on consumption of 50 wild and domestic species. The majority of meals contain no animal protein. However, respondents consume a wide range of wild species and 95% of respondents have eaten at least one protected species (and nearly 45% have eaten more than 10. The rural/urban divide and wealth are important predictors of bushmeat consumption, but the magnitude and direction of the effect varies between species. Bushmeat species are not preferred and are considered inferior to fish and domestic animals. Taboos have provided protection to some species, particularly the Endangered Indri, but we present evidence that this taboo is rapidly eroding. By considering a variety of potential influences on consumption in a single study we have improved understanding of who is eating bushmeat and why. Evidence that bushmeat species are not generally preferred meats suggest that projects which increase the availability of domestic meat and fish may have success at reducing demand. We also suggest that enforcement of existing wildlife and firearm laws should be a priority, particularly in areas undergoing rapid social change. The issue of hunting as an important threat to biodiversity in Madagascar is only now being fully recognised. Urgent action is required to ensure

Full Text Available Rapid changes in technology and economy that we observe nowadays are accompanied by rapid changes in traditional values and attitudes. In the contemporary world, a permanent proximity of internet, computer, television or smartphone makes us all citizens of the globalised, virtual world rather than a physical, geographical, real one. But even if people consider themselves to be citizens of the “global village”, a political architecture of the real world has remained based on the nation-state. One of the main characteristics of a nation-state is its territory defined by its borders. Recognition and respect of nation-state borders is considered to be a principle of national sovereignty, national interest and territorial independence, which shape international relations. Historically, rulers always usurped the right to control what happens on their territory, but there were some areas that had escaped their supervision. The first one is the sphere of science and more broadly – ideas. Whether it was religion, superstition or steam engine, ideas were unstoppable even for isolated countries. Second area is a realm of trade. Rulers were usually rather kind for merchants, therefore borders were always wide open for business people. It is worth mentioning that both ideas and trade are significant driving forces in the history of world. Their influence is sometimes stronger and sometimes weaker but it is always meaningful. Yet the very hypothesis of this article states that in contemporary, globalised world a third important factor has arrived. It was always present but until the economy hasn’t become globalized, its impact wasn’t noticeable. This third factor can be described as universalisation of western consumption patterns and it plays an important role particularly in developing countries.

Full Text Available Background: None of the studies of whole grains that have looked either at diet or weight/adiposity measures have focused exclusively on oatmeal. Objective: The objective of this study was to assess the association between oatmeal consumption and nutrient intake, diet quality, and weight/adiposity of children aged 2–18. Design: A nationally representative sample of children aged 2–18 (N=14,690 participating in National Health and Nutrition Examination Survey 2001–2010 was used. Intake was determined from a single 24-h dietary recall. Diet quality was measured using the Healthy Eating Index-2010 (HEI-2010. Covariate-adjusted regression analyses, using appropriate sample weights, were used to determine differences between oatmeal consumers and non-consumers for demographics, nutrient intakes, diet quality, and weight/adiposity measures (p<0.01. Logistic regression was performed to calculate odds ratios for weight measures and obesity (p<0.05. Results: Compared to non-consumers, oatmeal consumers were more likely to be younger and less likely to be smokers. Consumers had higher intakes of dietary fiber, vitamin A, thiamin, riboflavin, calcium, phosphorus, magnesium, iron, copper, and potassium, and significantly lower intakes of total, monounsaturated and saturated fatty acids, cholesterol, and sodium. Oatmeal consumers had higher dietary quality scores attributable to higher intakes of whole grains and lower intakes of refined grains and empty calories. Children consuming oatmeal were at lower risk for having central adiposity and being obese. Conclusions: Consumption of oatmeal by children was associated with better nutrient intake, diet quality, and reduced risk for central adiposity and obesity and should be encouraged as part of an overall healthful diet.

Seasonality directs contrasting food collection behavior and nutrient regulation strategies in ants.

Full Text Available Long-lived animals, including social insects, often display seasonal shifts in foraging behavior. Foraging is ultimately a nutrient consumption exercise, but the effect of seasonality per se on changes in foraging behavior, particularly as it relates to nutrient regulation, is poorly understood. Here, we show that field-collected fire ant colonies, returned to the laboratory and maintained under identical photoperiod, temperature, and humidity regimes, and presented with experimental foods that had different protein (p to carbohydrate (c ratios, practice summer- and fall-specific foraging behaviors with respect to protein-carbohydrate regulation. Summer colonies increased the amount of food collected as the p:c ratio of their food became increasingly imbalanced, but fall colonies collected similar amounts of food regardless of the p:c ratio of their food. Choice experiments revealed that feeding was non-random, and that both fall and summer ants preferred carbohydrate-biased food. However, ants rarely ate all the food they collected, and their cached or discarded food always contained little carbohydrate relative to protein. From a nutrient regulation strategy, ants consumed most of the carbohydrate they collected, but regulated protein consumption to a similar level, regardless of season. We suggest that varied seasonal food collection behaviors and nutrient regulation strategies may be an adaptation that allows long-lived animals to meet current and future nutrient demands when nutrient-rich foods are abundant (e.g. spring and summer, and to conserve energy and be metabolically more efficient when nutritionally balanced foods are less abundant.

Comparing the Life Cycle Energy Consumption, Global ...

Science.gov (United States)

Managing the water-energy-nutrient nexus for the built environment requires, in part, a full system analysis of energy consumption, global warming and eutrophication potentials of municipal water services. As an example, we evaluated the life cycle energy use, greenhouse gas (GHG) emissions and aqueous nutrient releases of the whole anthropogenic municipal water cycle starting from raw water extraction to wastewater treatment and reuse/discharge for five municipal water and wastewater systems. The assessed options included conventional centralized services and four alternative options following the principles of source-separation and water fit-for-purpose. The comparative life cycle assessment identified that centralized drinking water supply coupled with blackwater energy recovery and on-site greywater treatment and reuse was the most energyand carbon-efficient water service system evaluated, while the conventional (drinking water and sewerage) centralized system ranked as the most energy- and carbon-intensive system. The electricity generated from blackwater and food residuals co-digestion was estimated to offset at least 40% of life cycle energy consumption for water/waste services. The dry composting toilet option demonstrated the lowest life cycle eutrophication potential. The nutrients in wastewater effluent are the dominating contributors for the eutrophication potential for the assessed system configurations. Among the parameters for which variability

This effect is rather dependent on nutrient availability and may be species-specific. As changes in the carbon:nutrient stoichiometry of submerged aquatic plants can impact the transfer of energy to higher trophic levels, these results suggest that eutrophication may enhance plant consumption and decomposition, which could in turn have consequences for carbon sequestration.

Full Text Available The methodology used in the first Belgian food consumption survey followed to a large extent the instructions of the European Food Consumption (EFCOSUM reports, where repeated 24-hour recalls (24HR using EPIC-SOFT were recommended.To evaluate the relative validity of two non-consecutive 24HR using EPIC-SOFT by comparison with 5-day estimated dietary records (EDR. To assess misreporting in energy for both methods by comparing energy intake with energy expenditure from accelerometery in a subsample.A total of 175 subjects (aged 15 and over were recruited to participate in the study. Repeated 24HR were performed with an interval of 2–8 weeks. After completion of the second interview, subjects were instructed to keep an EDR. Dietary intakes were adjusted for within-person variability to reflect usual intakes. A Student's t-test was calculated to assess differences between both methods. Spearman and Kappa correlation coefficients were used to investigate agreement.In total, 127 subjects completed the required repeated 24HR, as well as the five record days. From 76 participants, accelerometer data were available. In both methods, about 35% of participants had ratios of Energy Intake/Total Energy Expenditure (EI/TEE above or below 95% confidence intervals for EI/TEE, suggesting misreporting of energy. Significant differences between the two dietary intake methods were found for total energy, total fat, fatty acids, cholesterol, alcohol, vitamin C, thiamine, riboflavin and iron. In general, intakes from 24HR were higher compared to EDR. Correlation coefficients for all nutrients ranged from 0.16 for thiamine to 0.70 for water.The results from this study show that in the context of nutritional surveillance, duplicate 24HR can be used to asses intakes of protein, carbohydrates, starch, sugar, water, potassium and calcium.

Although evidence supports that colorectal cancer (CRC) has an environmental etiology, the potential influence of diet appears to be one of the most important components. We studied the relation between food groups and nutrient intake and the risk of CRC. A hospital-based case-control study was conducted in Spain between 2007 and 2009. The authors matched 245 patients with incident histologically confirmed CRC by age, gender, and date of admission with 490 controls. Information about nutrient intake was gathered by using a semiquantitative frequency food questionnaire. Univariate analysis was done with individual food items. Odds ratios (ORs) for consecutive tertiles of nutrient intake were computed after allowance for sociodemographic variables and consumption of food groups. Vitamin B6 (OR: 0.26), vitamin D (OR: 0.45), vitamin E (OR: 0.42), polyunsaturated fatty acids (OR: 0.57), and fiber (OR: 0.40) were inversely associated with CRC, whereas carbohydrates (OR: 1.82) were significantly associated with CRC risk for the upper tertile. In multivariate analysis adjusting for major covariables (energy, age, and gender), vitamin D (OR:0.45), vitamin E (OR:0.36), and fiber (OR:0.46) remained associated with CRC. Data suggest that the etiology of colorectal cancer is not due to lifestyle and dietary patterns being important the effect of single nutrients.

The association between socioeconomic status and adult fast-food consumption in the U.S.

Science.gov (United States)

Zagorsky, Jay L; Smith, Patricia K

2017-11-01

Health follows a socioeconomic status (SES) gradient in developed countries, with disease prevalence falling as SES rises. This pattern is partially attributed to differences in nutritional intake, with the poor eating the least healthy diets. This paper examines whether there is an SES gradient in one specific aspect of nutrition: fast-food consumption. Fast food is generally high in calories and low in nutrients. We use data from the 2008, 2010, and 2012 waves of the National Longitudinal Survey of Youth (NLSY79) to test whether adult fast-food consumption in the United States falls as monetary resources rise (n=8136). This research uses more recent data than previous fast-food studies and includes a comprehensive measure of wealth in addition to income to measure SES. We find little evidence of a gradient in adult fast-food consumption with respect to wealth. While adults in the highest quintile are 54.5% less likely to report fast-food consumption than those in the lowest quintile, adults in the second and third quintiles are no less likely to report fast food-food intake than the poorest. Contrary to popular belief, fast-food consumption rises as income rises from the lowest to middle quintiles. The variation in adult fast-food consumption across income and wealth groups is, however, small. Those in the wealthiest quintile ate about one less fast-food meal on average than those in the lowest quintile. Other factors play a bigger role in explaining fast-food consumption: reading ingredient labels is negatively associated while soda consumption and hours of work are positively associated with fast-food consumption.

We present a method for self-assembling arrays of live single cells on a glass chip using a photopatternable polymer to form micro-traps. We have studied the single-cell self-assembly method and optimized the process to obtain a 52% yield of single-trapped cells. We also report a method to measure the oxygen consumption rate of a single cell using micro-patterned sensors. These molecular oxygen sensors were fabricated around each micro-trap allowing optical interrogation of oxygen concentration in the immediate environment of the trapped cell. Micromachined micro-wells were then used to seal the trap, sensor and cell in order to determine the oxygen consumption rate of single cells. These techniques reported here add to the collection of tools for performing 'singe-cell' biology. An oxygen consumption rate of 1.05 ± 0.28 fmol min −1 was found for a data set consisting of 25 single A549 cells.

Urban Forest and Rural Cities: Multi-sited Households, Consumption Patterns, and Forest Resources in Amazonia

Directory of Open Access Journals (Sweden)

Christine Padoch

2008-12-01

Full Text Available In much of the Amazon Basin, approximately 70% of the population lives in urban areas and urbanward migration continues. Based on data collected over more than a decade in two long-settled regions of Amazonia, we find that rural-urban migration in the region is an extended and complex process. Like recent rural-urban migrants worldwide, Amazonian migrants, although they may be counted as urban residents, are often not absent from rural areas but remain members of multi-sited households and continue to participate in rural-urban networks and in rural land-use decisions. Our research indicates that, despite their general poverty, these migrants have affected urban markets for both food and construction materials. We present two cases: that of açaí palm fruit in the estuary of the Amazon and of cheap construction timbers in the Peruvian Amazon. We find that many new Amazonian rural-urban migrants have maintained some important rural patterns of both consumption and knowledge. Through their consumer behavior, they are affecting the areal extent of forests; in the two floodplain regions discussed, tree cover is increasing. We also find changes in forest composition, reflecting the persistence of rural consumption patterns in cities resulting in increased demand for and production of açaí and cheap timber species.

Stress, breakfast cereal consumption and cortisol.

Science.gov (United States)

Smith, A P

2002-04-01

Recent research has shown that regular consumption of breakfast cereal is associated with lower stress levels and reports of better physical and mental health. The present study examined this issue using an objective indicator of stress, salivary cortisol. The results showed that stress was associated with higher cortisol levels and daily consumption of breakfast cereal was associated with lower cortisol levels. Although it was not possible to rule out all the alternative explanations of the association between breakfast cereal consumption and cortisol, analyses did show that the effect could not be accounted for by general health or nutritional status. The effects of breakfast cereal consumption and stress were also independent, which shows that the effects of breakfast found here cannot be due to stress buffering. Further research manipulating the nutrient content of the breakfast cereal is now required to provide further information about the mechanisms underlying this effect.

To examine the consumer behavior sector of energy demand patterns in Canada, this report undertook to identify major groupings of households based on energy consumption profiles and energy values, to relate these groupings to situational and demographic factors, and to initiate a comparative analysis of the receptivity of the major groupings to alternative energy conservation policy proposals. Data were collected from household surveys and energy suppliers. Householders were asked about their attitudes to energy conservation and energy policy, and profiles of energy consumption patterns of typical households were identified. To aid in evaluating the research, households were classified according to their levels of in-home energy consumption and automobile gasoline consumption. The findings indicated a range of lifestyles highly interrelated in terms of levels of energy consumption, ownership of energy-consuming products, knowledge and concern for energy issues, willingness to cut back energy consumption, and preferences for alternative conservation policies. The study has shown that most consumers are not very aware of the energy problem, do not see conservation as a serious need, and are unlikely to accept major policy interventions that result in major changes in energy supplies and current lifestyles. A number of recommendations are made as to policies, and their possible impact, to conserve household energy. 8 refs. 11 tabs.

The present research aimed to analyse the nutrient density (ND), nutrient adequacy score (NAS) and energy density (ED) of Indonesian foods and to formulate a balanced diet using linear programming. Data on typical Indonesian diets were obtained from the Indonesian Socio-Economic Survey 2008. ND was investigated for 122 Indonesian foods. NAS was calculated for single nutrients such as Fe, Zn and vitamin A. Correlation analysis was performed between ND and ED, as well as between monthly expenditure class and food consumption pattern in Indonesia. Linear programming calculations were performed using the software POM-QM for Windows version 3. Republic of Indonesia, 2008. Public households (n 68 800). Vegetables had the highest ND of the food groups, followed by animal-based foods, fruits and staple foods. Based on NAS, the top ten food items for each food group were identified. Most of the staple foods had high ED and contributed towards daily energy fulfillment, followed by animal-based foods, vegetables and fruits. Commodities with high ND tended to have low ED. Linear programming could be used to formulate a balanced diet. In contrast to staple foods, purchases of fruit, vegetables and animal-based foods increased with the rise of monthly expenditure. People should select food items based on ND and NAS to alleviate micronutrient deficiencies in Indonesia. Dietary formulation calculated using linear programming to achieve RDA levels for micronutrients could be recommended for different age groups of the Indonesian population.

Consumption of a healthy dietary pattern results in significant reductions in C-reactive protein levels in adults: a meta-analysis.

Consumption of healthy dietary patterns has been associated with reduced risk of cardiovascular disease and metabolic syndrome. Dietary intervention targets disease prevention, so studies increasingly use biomarkers of underlying inflammation and metabolic syndrome progression to examine the diet-health relationship. The extent to which these biomarkers contribute to the body of evidence on healthy dietary patterns is unknown. The aim of this meta-analysis was to determine the effect of healthy dietary patterns on biomarkers associated with adiposity, insulin resistance, and inflammation in adults. A systematic search of Scopus, PubMed, Web of Science, and Cochrane Central Register of Controlled Trials (all years to April 2015) was conducted. Inclusion criteria were randomized controlled trials; effects of dietary patterns assessed on C-reactive protein (CRP), total adiponectin, high-molecular-weight adiponectin, tumor necrosis factor-α, adiponectin:leptin, resistin, or retinol binding protein 4. Random effects meta-analyses were conducted to assess the weighted mean differences in change or final mean values for each outcome. Seventeen studies were included in the review. These reflected research on dietary patterns associated with the Mediterranean diet, Nordic diet, Tibetan diet, and the Dietary Approaches to Stop Hypertension diet. Consumption of a healthy dietary pattern was associated with significant reductions in CRP (weighted mean difference, -0.75 [-1.16, -0.35]; P = .0003). Non-significant changes were found for all other biomarkers. This analysis found evidence for favorable effects of healthy dietary patterns on CRP, with limited evidence for other biomarkers. Future research should include additional randomized controlled trials incorporating a greater range of dietary patterns and biomarkers. Copyright © 2016 Elsevier Inc. All rights reserved.

The present study aims to identify the dietary patterns of adolescents and associate these patterns with overweight. We analyzed food-consumption data from 6784 adolescents in the age group 10-18 years old collected in the Household Budget Survey 2008-2009. Dietary patterns were assessed through exploratory factor analysis. Logistic regression models were used in order to associate dietary patterns with overweight. Four dietary patterns were recorded: Traditional Brazilian Pattern, Snacks Pattern, Fast Food Pattern, and the Milk, Fruit and Cereal Breakfast Pattern. Results were adjusted according to the sociodemographic variables and showed that the higher the adherence to Snacks (OR: 1.50 fifth quintile vs first (95% CI: 1.13, 1.99) p linear trend <0.001) and Fast Food patterns (OR: 1.55 fifth quintile vs first (95% CI = 1.12, 2.12) p linear trend <0.001), the higher the chances of becoming overweight. These data indicate that the local public health and nutrition policies focused on adolescents should be more attentive to the eating habits of this population in Brazil, since the current research related regular poor nutritional quality dietary patterns to increased overweight among adolescents. In addition, understanding adolescents' eating habits according to their dietary patterns may guide the development of healthy dietary recommendations based on the combination between food and food groups, rather than only on nutrients or nutritional adequacy.

Castle, S.C.; Neff, J.C.

2009-01-01

We investigated the role of rock-derived mineral nutrient availability on the nutrient dynamics of overlying forest communities (Populus tremuloides and Picea engelmanni-Abies lasiocarpa v. arizonica) across three parent materials (andesite, limestone, and sandstone) in the southern Rocky Mountains of Colorado. Broad geochemical differences were observed between bedrock materials; however, bulk soil chemistries were remarkably similar between the three different sites. In contrast, soil nutrient pools were considerably different, particularly for P, Ca, and Mg concentrations. Despite variations in nutrient stocks and nutrient availability in soils, we observed relatively inflexible foliar concentrations and foliar stoichiometries for both deciduous and coniferous species. Foliar nutrient resorption (P and K) in the deciduous species followed patterns of nutrient content across substrate types, with higher resorption corresponding to lower bedrock concentrations. Work presented here indicates a complex plant response to available soil nutrients, wherein plant nutrient use compensates for variations in supply gradients and results in the maintenance of a narrow range in foliar stoichiometry. ?? 2008 Springer Science+Business Media, LLC.

Poor dietary habits among drug addicts represent health hazards. However, very few studies have focused on dietary intake as an independent health risk factor in relation to this group. The objective of the present study was to examine the dietary habits of drug addicts living on the fringes of an affluent society. The study focused on food access, food preferences, intake of energy and nutrients, and related nutrient blood concentrations. The respondent group consisted of 123 male and seventy-two female drug addicts, who participated in a cross-sectional study that included a 24 h dietary recall, blood samples, anthropometrical measurements and a semi-structured interview concerning food access and preferences. Daily energy intake varied from 0 to 37 MJ. Food received from charitable sources and friends/family had a higher nutrient density than food bought by the respondents. Added sugar accounted for 30 % of the energy intake, which was mirrored in biomarkers. Sugar and sugar-sweetened food items were preferred by 61 % of the respondents. Of the respondents, 32 % had a TAG concentration above the reference values, while 35 % had a cholesterol concentration beneath the reference values. An elevated serum Cu concentration indicated inflammation among the respondents. Further research on problems related to the diets of drug addicts should focus on dietary habits and aim to uncover connections that may reinforce inebriation and addiction.

Context-dependent effects of nutrient loading on the coral-algal mutualism.

Shantz, Andrew A; Burkepile, Deron E

Human-mediated increases in nutrient availability alter patterns of primary production, impact species diversity, and threaten ecosystem function. Nutrients can also alter community structure by disrupting the relationships between nutrient-sharing mutualists that form the foundation of communities. Given their oligotrophic nature and the dependence of reef-building corals on symbiotic relationships, coral reefs may be particularly vulnerable to excess nutrients. However, individual studies suggest complex, even contradictory, relationships among nutrient availability, coral physiology, and coral growth. Here, we used meta-analysis to establish general patterns of the impact of nitrogen (N) and phosphorus (P) on coral growth and photobiology. Overall, we found that over a wide range of concentrations, N reduced coral calcification 11%, on average, but enhanced metrics of coral photobiology, such as photosynthetic rate. In contrast, P enrichment increased average calcification rates by 9%, likely through direct impacts on the calcification process, but minimally impacted coral photobiology. There were few synergistic impacts of combined N and P on corals, as the nutrients impact corals via different pathways. Additionally, the response of corals to increasing nutrient availability was context dependent, varying with coral taxa and morphology, enrichment source, and nutrient identity. For example, naturally occurring enrichment from fish excretion increased coral growth, while human-mediated enrichment tended to decrease coral growth. Understanding the nuances of the relationship between nutrients and corals may allow for more targeted remediation strategies and suggest how other global change drivers such as overfishing and climate change will shape how nutrient availability impacts corals.

Television viewing and food consumption in Flemish adolescents in Belgium.

Vereecken, Carine Anna; Maes, Lea

2006-01-01

To examine associations of television viewing with overall food consumption A computerised 24-hour dietary recall and a questionnaire were completed by 1031 adolescents (+/- 12-14 years of age). Those who generally watched more television were more likely to consume frequently advertised items such as soft drinks and snacks. Not all frequently advertised food items (e.g. cereals) were associated with television viewing. An inverse association was found with fruit, water and milk. A negative association was found with brown bread; a positive association was found with white bread. The results indicate that high television viewing and a less nutrient dense food pattern are part of a lifestyle influenced by common underlying factors. Nutrition interventions aimed at improving adolescents' food habits should target high television-viewers. Our findings underline the importance of tackling socio-demographic differences.

Evidence that diet is associated with breast cancer risk is inconsistent. Most studies have examined risks associated with specific foods and nutrients, rather than measures of overall diet. This study aimed to evaluate dietary patterns and their relation to breast cancer risk in a large cohort of women. Data from 91,779 women in the California Teachers Study cohort were analyzed, including data from 4140 women with a diagnosis of invasive breast cancer made between 1995 and 2009. Five predominant dietary patterns were identified by using principal components factor analysis: a plant-based diet, high in fruit and vegetables; a high-protein, high-fat diet, high in meats, eggs, fried foods, and high-fat condiments; a high-carbohydrate diet, high in convenience foods, pasta, and bread products; an ethnic diet, high in legumes, soy-based foods, rice, and dark-green leafy vegetables; and a salad and wine diet, high in lettuce, fish, wine, low-fat salad dressing, and coffee and tea. The plant-based pattern was associated with a reduction in breast cancer risk (RR: 0.85; 95% CI: 0.76, 0.95 for the highest compared with the lowest consumption quintile; P-trend = 0.003); risk reduction was greater for estrogen receptor-negative progesterone receptor-negative (ER-PR-) tumors (RR: 0.66; 95% CI: 0.48, 0.91; P-trend = 0.03). The salad and wine pattern was associated with an increased risk of estrogen receptor-positive progesterone receptor-positive tumors (RR: 1.29; 95% CI: 1.12, 1.49); this effect was only slightly attenuated after adjustment for alcohol consumption. The finding that greater consumption of a plant-based dietary pattern is associated with a reduced breast cancer risk, particularly for ER-PR- tumors, offers a potential avenue for prevention.

Temperature and nutrient availability play key roles in controlling the pathways and rates at which energy and materials move through ecosystems. These factors have also changed dramatically on Earth over the past century as human activities have intensified. Although significant effort has been devoted to understanding the role of temperature and nutrients in isolation, less is known about how these two factors interact to influence ecological processes. Recent advances in ecological stoichiometry and metabolic ecology provide a useful framework for making progress in this area, but conceptual synthesis and review are needed to help catalyze additional research. Here, we examine known and potential interactions between temperature and nutrients from a variety of physiological, community, and ecosystem perspectives. We first review patterns at the level of the individual, focusing on four traits--growth, respiration, body size, and elemental content--that should theoretically govern how temperature and nutrients interact to influence higher levels of biological organization. We next explore the interactive effects of temperature and nutrients on populations, communities, and food webs by synthesizing information related to community size spectra, biomass distributions, and elemental composition. We use metabolic theory to make predictions about how population-level secondary production should respond to interactions between temperature and resource supply, setting up qualitative predictions about the flows of energy and materials through metazoan food webs. Last, we examine how temperature-nutrient interactions influence processes at the whole-ecosystem level, focusing on apparent vs. intrinsic activation energies of ecosystem processes, how to represent temperature-nutrient interactions in ecosystem models, and patterns with respect to nutrient uptake and organic matter decomposition. We conclude that a better understanding of interactions between temperature and

It has often been suggested that cardiovascular mortality and their geographical heterogeneity are associated with nutrients intake patterns and also lipid profile. The large Spanish study Dieta y Riesgo de Enfermedades Cardiovasculares en España (DRECE) investigated this theory from 1991 to 2010. Out of the 4,783 Spanish individuals making up the DRECE cohort, 220 subjects (148 men and 72 women) died (4.62%) during the course of the study. The mean age of patients who died from cardiovascular causes (32 in all) was 61.08 years 95% CI (57.47-64.69) and 70.91% of them were males. The consumption of nutrients and the lipid profile by geographical area, studied by geospatial models, showed that the east and southern area of the country had the highest fat intake coupled to a high rate of unhealthy lipid profile. It was concluded that the spatial geographical analysis showed a relationship between high fat intake, unhealthy lipid profile and cardiovascular mortality in the different geographical areas, with a high variability within the country.

Results of reconstruction of food consumption patterns are presented for the residents of Ozyorsk for the period of 1948-1966. The reconstruction was performed on the basis analysis of the archive data. The given period of time is characterized by maximum releases into the atmosphere from the Mayak PA sources, and, therefore, it is considered to be the most significant period for calculating peroral component contribution to effective exposure doses to the population. The paper describes main foodstuff suppliers (regions) and their economic indices, as well as delivery rates and consumption rates for most important foodstuffs (primarily whole milk).

under- or overreported (depending on the net trade flow). Factors that influence consumption and trade patterns include variations in industry structure, labor or financial markets, legislation, and technology. As U.S. trade patterns of manufactured products change, omitting mineral commodities incorporated into these goods as part of U.S. mineral commodity consumption estimates may affect the interpretation of observed trends in minerals consumption and trade. Although it may be desirable to include minerals contained in manufactured products as part of consumption estimates, collection and estimation of these data are sometimes difficult. Consumption and trade data for every traded product may not be readily available. Compiling comprehensive consumption statistics for mineral commodities, which have many end uses, each including multiple products, may be time consuming. For these reasons, studies of all mineral commodities are not feasible. Mineral commodity selection for this study is based on data accessibility considerations and the relative importance of lead contained in imported and exported products when considered part of total U.S. lead consumption. Lead was selected for this initial evaluation of total mineral consumption because of the need to understand the consumption pattern of this potentially toxic metal and its compounds, the relative simplicity of this sector?s end-use structure, and the availability of trade data. This study draws upon the findings of an earlier lead consumption study (Biviano and others, 1999) conducted by the USGS for the period 1984 to 1993, but uses a different study methodology for an industry whose structure has changed from that considered in the earlier study. Figure 1 shows the quantity of material contributing to U.S. total consumption of lead metal from domestic and foreign industrial sectors in 2004, based upon trade data reported by the USGS and the U.S. International Trade Commission (USITC).

A dominant paradigm in ecology is that plants are limited by nitrogen (N) during primary succession. Whether generalizable patterns of nutrient limitation are also applicable to metabolically and phylogenetically diverse soil microbial communities, however, is not well understood. We investigated if measures of N and phosphorus (P) pools inform our understanding of the nutrient(s) most limiting to soil microbial community activities during primary succession. We evaluated soil biogeochemical properties and microbial processes using two complementary methodological approaches-a nutrient addition microcosm experiment and extracellular enzyme assays-to assess microbial nutrient limitation across three actively retreating glacial chronosequences. Microbial respiratory responses in the microcosm experiment provided evidence for N, P and N/P co-limitation at Easton Glacier, Washington, USA, Puca Glacier, Peru, and Mendenhall Glacier, Alaska, USA, respectively, and patterns of nutrient limitation generally reflected site-level differences in soil nutrient availability. The activities of three key extracellular enzymes known to vary with soil N and P availability developed in broadly similar ways among sites, increasing with succession and consistently correlating with changes in soil total N pools. Together, our findings demonstrate that during the earliest stages of soil development, microbial nutrient limitation and activity generally reflect soil nutrient supply, a result that is broadly consistent with biogeochemical theory.

To examine the consumer behavior sector of energy demand patterns in Canada, this report undertook to identify major groupings of households based on energy consumption profiles and energy values, to relate these groupings to situational and demographic factors, and to initiate a comparative analysis of the receptivity of the major groupings to alternative energy conservation policy proposals. Data were collected from household surveys and energy suppliers. Householders were asked about their attitudes to energy conservation and energy policy, and profiles of energy consumption patterns of typical households were identified. To aid in evaluating the research, households were classified according to their levels of in-home energy consumption and automobile gasoline consumption. The findings indicated a range of lifestyles highly interrelated in terms of levels of energy consumption, ownership of energy-consuming products, knowledge and concern for energy issues, willingness to cut back energy consumption, and preferences for alternative conservation policies. The study has shown that most consumers are not very aware of the energy problem, do not see conservation as a serious need, and are unlikely to accept major policy interventions that result in major changes in energy supplies and current lifestyles. A number of recommendations are made as to policies, and their possible impact, to conserve household energy. 8 refs. 11 tabs.

Full Text Available Abstract Background We studied food consumption and nutrient intake in subjects with depressed mood, anxiety and insomnia as indices of compromised mental wellbeing. Methods The study population consisted of 29,133 male smokers aged 50 to 69 years who entered the Alpha-Tocopherol, Beta-Carotene Cancer Prevention Study in 1985–1988. This was a placebo-controlled trial to test whether supplementation with alpha-tocopherol or beta-carotene prevents lung cancer. At baseline 27,111 men completed a diet history questionnaire from which food and alcohol consumption and nutrient intake were calculated. The questionnaire on background and medical history included three symptoms on mental wellbeing, anxiety, depression and insomnia experienced in the past four months. Results Energy intake was higher in men who reported anxiety or depressed mood, and those reporting any such symptoms consumed more alcohol. Subjects reporting anxiety or depressed mood had higher intake of omega-3 fatty acids and omega-6 fatty acids. Conclusions Our findings conflict with the previous reports of beneficial effects of omega-3 fatty acids on mood.

However, EF problems may not directly affect HCLN intake across time, except when problems are associated with child perception of more frequent parent consumption of convenience foods. Future research is needed to investigate the possibility that helping children perceive and understand role models' convenience food consumption may improve child dietary consumption patterns. © 2014 Society for Public Health Education.

Bacterial growth and DOC consumption in a tropical coastal lagoon

Full Text Available The aims of this research were to determine the main limiting nutrient to bacterial growth in Imboassica lagoon, southeastern Brazil, to estimate the percentage of dissolved organic carbon (DOC available for bacterial growth, and to determine the bacterial growth efficiency (BGE of natural assemblages. Bacterial growth and DOC consumption were determined in batch culture experiments, in which water samples were supplemented with nitrogen and phosphorus together or separately, or incubated without nutrient additions. When added together, N and P stimulated higher bacterial growth rates and production, as well as higher DOC consumption. The BGEs and DOC consumption rates were strongly dependent on the method used to determine bacterial production. The BGE ranged from 11 to 72%. However, only a minor fraction of bulk DOC was consumed by the planktonic bacteria (from 0.7 to 3.4%. The results suggest that low availability of phosphorus and nitrogen coupled with excess organic carbon was the main factor responsible for the relatively low bacterial utilization of DOC in Imboassica lagoon.

Highlights: • A model to describe spatiotemporal building energy demand patterns was developed. • The model integrates existing methods in urban and energy planning domains. • The model is useful to analyze energy efficiency strategies in neighborhoods. • Applicability in educational, urban and energy planning practices was found. - Abstract: We introduce an integrated model for characterization of spatiotemporal building energy consumption patterns in neighborhoods and city districts. The model addresses the need for a comprehensive method to identify present and potential states of building energy consumption in the context of urban transformation. The focus lies on determining the spatiotemporal variability of energy services in both standing and future buildings in the residential, commercial and industrial sectors. This detailed characterization facilitates the assessment of potential energy efficiency measures at the neighborhood and city district scales. In a novel approach we integrated existing methods in urban and energy planning domains such as spatial analysis, dynamic building energy modeling and energy mapping to provide a comprehensive, multi-scale and multi-dimensional model of analysis. The model is part of a geographic information system (GIS), which serves as a platform for the allocation and future dissemination of spatiotemporal data. The model is validated against measured data and a peer model for a city district in Switzerland. In this context, we present practical applications in the analysis of energy efficiency measures in buildings and urban zoning. We furthermore discuss potential applications in educational, urban and energy planning practices

The consumption of two healthy diets (Mediterranean (MED) and low-fat (LF) diets) may restore the gut microbiome dysbiosis in obese patients depending on the degree of metabolic dysfunction. The differences in bacterial community at baseline and after 2 years of dietary intervention of 106 subjects from the CORDIOPREV study were analyzed, 33 of whom were obese patients with severe metabolic disease (5 criteria for metabolic syndrome) (MetS-OB), 32 obese patients without metabolic dysfunction (2 or less criteria for metabolic syndrome) (NonMetS-OB) and 41 non-obese subjects (NonMetS-NonOB). Our study showed a marked dysbiosis in people with severe metabolic disease (Met-OB), compared with obese people without MetS (NonMetS-OB) and non-obese people (NonMetS-NonOB). This disbiotic pattern was reversed by consumption of both MED (35% of calories as fat (22% MUFA fat, 6% PUFA fat and <10% saturated fat) or LF (<30% total fat (<10% saturated fat, 12%-14% MUFA fat and 6-8% PUFA fat) diets, whereas no significant microbiota changes were observed in NonMetS-NonOB and NonMetS-OB groups. Our results suggest that the chronic intake of two healthy dietary patterns partially restores the gut microbiome dysbiosis in obese patients with coronary heart disease, depending on the degree of metabolic dysfunction. © 2017 WILEY-VCH Verlag GmbH & Co.

An inadequate diet and physical inactivity may compound the many deleterious effects of smoking on health. Some research indicates that smoking behavior is related to other health behaviors, but little research has examined how smoking may be related to dietary intake of key nutrients, consumption of fast food, sedentary lifestyle, or weight status. The purpose of this study was to describe smoking frequency among adolescents and its relationship to physical activity and dietary patterns. The research study employed a cross-sectional, population-based design. Adolescents self-reported cigarette smoking, physical activity, and eating behaviors on the Project EAT (Eating Among Teens) survey and reported dietary intake on a food frequency questionnaire completed in school classrooms. The sample included 4746 middle school and high school students from Minneapolis-St. Paul public schools. Mixed-model regression, which was controlled for sex, race and ethnicity, socioeconomic status, grade level (middle school or high school), and school, was used to examine the association of smoking with diet and physical activity patterns. Overall, reported smoking frequency was inversely related to participating in team sports, eating regular meals, and consuming healthful foods and nutrients. Smoking frequency was directly related to frequency of fast-food and soft drink consumption. Adolescents who smoke cigarettes may be less likely to engage in health-promoting lifestyle behaviors. Interventions are needed to prevent smoking and the unhealthy dietary practices and physical activity behaviors that may be associated with it.

Essential nutrient requirements of the elderly

Full Text Available Robert Skully Department of Family Medicine, Grant Medical Center, OhioHealth, Columbus, OH, USA Abstract: Government-sponsored medical organizations in developed countries have established guidelines for daily nutritional requirements. For most nutrients there is general agreement surrounding these requirements, which are based on exhaustive scientific literature review. Differences in these recommendations exist because of genetic and environmental factors that result in differences in disease susceptibility, but also due to incomplete understanding of the roles of nutrients in disease prevention. This review briefly summarizes nutrient recommendations for older adults such as where those recommendations differ from those of younger adults; and includes areas of developing understanding such as the possible role of thiamine deficiency in patients with congestive heart failure, the need for some older adults to ingest absorbable forms of vitamin B12, the high prevalence of vitamin D deficiency, the potential role of vitamin K in bone health, the need for higher levels of protein intake in order to stimulate muscle protein synthesis as one ages, the role of calcium in osteoporosis, and the possible need for zinc supplementation in hospitalized patients.

A cross-sectional, population-based study was conducted on a random sample of 427 elderly individuals living in Porto Alegre, Brazil, to establish the nutrient consumption profile and verify its association with sociodemographic and health variables. Dietary intake was assessed using the 24-hour Food Recall Survey and the Dietetic Research Investigation technique. Seventy percent of the elderly respondents were women: 48.5% were between 60 and 69 years old; 68.8% had less than 8 years of schooling; 39% had a family income of between 2 and 5 minimum wages and 58.4% took no physical exercise. Hypertension was the most prevalent disease among the elderly and 54.9% were underweight. Men consumed more calories, protein, fiber, minerals and vitamins than women. Carbohydrate and calcium intake increases with advancing age, while zinc intake decreases. Physical exercise increased the intake of calories, magnesium, potassium and phosphorus. The higher the schooling the greater the intake of vitamins B6 and B12; the higher the family income, the greater the consumption of vitamin B6 and folic acid. The results show that there are nutritional deficiencies in the daily diet of the Brazilian elderly population, especially among women and individuals over 80 years of age.

Successional dynamics drive tropical forest nutrient limitation

Chou, C.; Hedin, L. O. O.

It is increasingly recognized that nutrients such as N and P may significantly constrain the land carbon sink. However, we currently lack a complete understanding of these nutrient cycles in forest ecosystems and how to incorporate them into Earth System Models. We have developed a framework of dynamic forest nutrient limitation, focusing on the role of secondary forest succession and canopy gap disturbances as bottlenecks of high plant nutrient demand and limitation. We used succession biomass data to parameterize a simple ecosystem model and examined the dynamics of nutrient limitation throughout tropical secondary forest succession. Due to the patterns of biomass recovery in secondary tropical forests, we found high nutrient demand from rapid biomass accumulation in the earliest years of succession. Depending on previous land use scenarios, soil nutrient availability may also be low in this time period. Coupled together, this is evidence that there may be high biomass nutrient limitation early in succession, which is partially met by abundant symbiotic nitrogen fixation from certain tree species. We predict a switch from nitrogen limitation in early succession to one of three conditions: (i) phosphorus only, (ii) phosphorus plus nitrogen, or (iii) phosphorus, nitrogen, plus light co-limitation. We will discuss the mechanisms that govern the exact trajectory of limitation as forests build biomass. In addition, we used our model to explore scenarios of tropical secondary forest impermanence and the impacts of these dynamics on ecosystem nutrient limitation. We found that secondary forest impermanence exacerbates nutrient limitation and the need for nitrogen fixation early in succession. Together, these results indicate that biomass recovery dynamics early in succession as well as their connection to nutrient demand and limitation are fundamental for understanding and modeling nutrient limitation of the tropical forest carbon sink.
