Among students, little is known about the physical and social context of eating lunch. The objective of this study was to determine if food intake (including the type of food and beverages and portion sizes) was associated with specific aspects of the physical and social lunch environment (location, with whom lunch was consumed, who prepared the food, and where the food was originally purchased). A total of 1236 participants (males = 659, females = 566) in grades 6 (n = 359), 7 (n = 409), and 8 (n = 463) from southern Ontario, Canada, completed the Food Behavior Questionnaire during the 2005-2006 academic year. A total of 8159 foods and 2200 beverages were consumed during the lunch meal, which contributed to 552 kcal (SD = 429) or 30% (SD = 16) of total daily energy intake (kcal/day). Higher amounts of energy, meats and alternatives, other foods, fried foods, and pizza were consumed when participants ate in between places or at a restaurant/fast food outlet (compared with at home or school, p lunch, despite a school board-level policy restricting the sales of "junk food," which appears to be brought from home. Our findings support schools in policy efforts that restrict fast food access (by leaving school grounds, preventing fast food companies from coming onto school grounds, or restricting sugar-sweetened beverage sales in vending machines) and that eating in between places should be discouraged.

An Innovative Method of Measuring Changes in Access to Healthful Foods in School Lunch Programs: Findings from a Pilot Evaluation.

Directory of Open Access Journals (Sweden)

Full Text Available A large local health department in Colorado partnered with 15 school districts to develop an approach to evaluate changes in access to healthy foods in reimbursable school lunches and a la carte offerings.School district nutrition managers were engaged at the start of this project. Health department dietitians developed criteria to classify food items as "Lower Fat and less added Sugar" (LFS and "Higher Fat and more added Sugar" (HFS based on the percentage of calories from fat and grams of added sugar. Lunch production sheets were obtained for two time periods, food items and the number of planned servings recorded. LFS and HFS planned servings were summed for each time period, and a LFS to HFS ratio calculated by dividing LFS planned servings by HFS planned servings. Additional analyses included calculating LFS: HFS ratios by school district, and for a la carte offerings.In 2009, the LFS: HFS ratio was 2.08, in 2011, 3.71 (P<0.0001. The method also detected changes in ratios at the school district level. For a la carte items, in 2009 the ratio of LFS: HFS was 0.53, and in 2011, 0.61 (not statistically significant.This method detected an increase in the LFS: HFS ratio over time and demonstrated that the school districts improved access to healthful food/drink by changing the contents of reimbursable school lunches. The evaluation method discussed here can generate information that districts can use in helping sustain and expand their efforts to create healthier environments for children and adults. Although federal regulations now cover all food and beverages served during the school day, there are still opportunities to improve and measure changes in food served in other settings such as child care centers, youth correction facilities, or in schools not participating in the National School Lunch Program.

Childcare centres (CCs) typically offer one meal and snacks daily. This study compared what is served in CCs with what the nutritional recommendations are; described and compared the nutritional composition of lunches served in CCs in New Brunswick and Saskatchewan; and examined differences between French and English, and urban and rural centres. The study involved 61 randomly selected CCs in New Brunswick and Saskatchewan, Canada. Lunch content was measured on two consecutive days by weighing each food item served to children and by visually documenting the food items using digital photography. Food items were categorized into food groups according to Health Canada's Eating Well with Canada's Food Guide, and nutrients were analyzed using a nutritional analysis software. One-sample t tests compared lunch content with nutritional recommendations. Independent t tests compared the nutrient and food group content of lunches in New Brunswick and Saskatchewan, French and English, and urban and rural CCs. On average, CCs did not meet provincial recommendations. Lunches in both provinces were low in calories (<517 kcal) and fibre (<7 g). Overall, Saskatchewan centres served greater amounts of food than New Brunswick centres (p < 0.05). French-speaking centres provided less fat (p = 0.047), less saturated fat (p = 0.01), and fewer servings of meat and alternatives (p = 0.02), and more trans fat (p = 0.03) than English-speaking centres. There were no differences between rural and urban centres. Few CC lunches met nutritional recommendations. Interventions are required to improve the quality of foods offered in CCs. Reviewing or developing comprehensive nutrition guidelines is warranted.

Background 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 policy makers, students, and their families. Purpose 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. Methods 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 two-year pilot study (2007-2009) where a professional chef trained cafeteria staff to make healthier school meals. The costs associated with food waste were calculated and the percent of foods consumed was compared with a gold standard of 85% consumption. Analyses were conducted in 2010-2011. Results 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 Boston middle schools. For most meal components, significantly less than 85% was consumed. Conclusions 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 would benefit if additional focus was given to the quality and palatability of school meals. PMID:23332326

School Lunch Programs in Israel, Past and Present

Directory of Open Access Journals (Sweden)

Endevelt, Ronit

2007-07-01

Full Text Available The first lunch programs in Palestine were the “soup kitchens,” which were established in Jerusalem before the First World War to feed the poor. Then, in 1923, Henrietta Szold launched a lunch initiative in schools in order to supply basic nutrition to students. As the children at most of the schools prepared the meals themselves with local products, they also learned good, low-cost eating habits and the appropriate use of domestic goods and had educational goals as well. These educational goals were in line with Zionist ideology. School lunch programs lasted through the early years of the nation of Israel, albeit without official governmental support, but they came to an end amid the rising prosperity of the early 1970s. In 2004, in response to the alarming results of a food security survey conducted by the Ministry of Health, the Knesset passed a law establishing a new school lunch program on a trial basis. This article reviews the history of lunch programs in Israel, highlighting both their achievements and their limitations, in order to establish a framework for judging the success of the current school lunch policy.

Lunch-time food choices in preschoolers: relationships between absolute and relative intake of different food categories, and appetitive characteristics and weight

Children’s appetitive characteristics measured by parent-report questionnaires are reliably associated with body weight, as well as behavioral tests of appetite, but relatively little is known about relationships with food choice. As part of a larger preloading study, we served 4-5y olds from primary school classes five school lunches at which they were presented with the same standardized multi-item meal. Parents completed Child Eating Behavior Questionnaire (CEBQ) sub-scales assessing satiety responsiveness (CEBQ-SR), food responsiveness (CEBQ-FR) and enjoyment of food (CEBQ-EF), and children were weighed and measured. Despite differing preload conditions, children showed remarkable consistency of intake patterns across all five meals with day-to-day intra-class correlations in absolute and percentage intake of each food category ranging from .78 to .91. Higher CEBQ-SR was associated with lower mean intake of all food categories across all five meals, with the weakest association apparent for snack foods. Higher CEBQ-FR was associated with higher intake of white bread and fruits and vegetables, and higher CEBQ-EF was associated with greater intake of all categories, with the strongest association apparent for white bread. Analyses of intake of each food group as a percentage of total intake, treated here as an index of the child’s choice to consume relatively more or relatively less of each different food category when composing their total lunch-time meal, further suggested that children who were higher in CEBQ-SR ate relatively more snack foods and relatively less fruits and vegetables, while children with higher CEBQ-EF ate relatively less snack foods and relatively more white bread. Higher absolute intakes of white bread and snack foods were associated with higher BMI z score. CEBQ sub-scale associations with food intake variables were largely unchanged by controlling for daily metabolic needs. However, descriptive comparisons of lunch intakes with

The objective of this study was to evaluate an intervention that combined mindful eating and online pre-ordering to promote healthier lunch purchases at work. The study took place at an urban hospital with 26 employees who were overweight or obese. The design included a contemporaneous comparison with delayed-treatment control and a three-phase prospective study. A minimum 4-week baseline period preceded a 4-week full-intervention, in which participants received mindful eating training, pre-ordered their lunches, and received price discounts toward lunch purchases. In a 4-week reduced intervention phase, participants pre-ordered lunches without price discounts. Participant lunch purchases were tracked electronically at the point of purchase. The primary outcome measures were the amounts of kilocalories and fat grams in purchased lunches. In contemporaneous comparisons, the treatment group purchased lunches with an average of 144.6 fewer kilocalories (p = 0.01) and 8.9 fewer grams of fat (p = 0.005) compared to controls. In multivariable longitudinal analyses, participants decreased the average number of calories in their meals by 114.6 kcal per lunch and the average grams of fat by 5.4 per lunch during the partial-intervention compared to the baseline (p ordering system if offered in the future. Combined mindful eating training and online pre-ordering appears a feasible and useful worksite intervention to improve food choices by employees. Copyright © 2014 Elsevier Ltd. All rights reserved.

This study assessed the impact of changes in school food policy on student lunch consumption in middle schools. Two years of lunch food records were collected from students at three middle schools in the Houston, Texas area. During the first year, no changes occurred in the school food environment. After that school year was completed, chips and dessert foods were removed from the snack bars of all schools by the Food Service Director. Students recorded the amount and source of food and beverage items consumed. Point-of-service purchase machines provided a day-by-day electronic data file with food and beverage purchases from the snack bars during the 2-year period. Independent t-tests and time series analyses were used to document the impact of the policy change on consumption and sales data between the two years. In general, student consumption of sweetened beverages declined and milk, calcium, vitamin A, saturated fat and sodium increased after the policy change. Snack chips consumption from the snack bar declined in year 2; however, consumption of snack chips and candy from vending increased and the number of vending machines in study schools doubled during the study period. Ice cream sales increased significantly in year 2. Policy changes on foods sold in schools can result in changes in student consumption from the targeted environments. However, if all environments do not make similar changes, compensation may occur.

Full Text Available The aim of this study was to determine the environmental impact, nutrient intake, appreciation and tastiness of three buffet-style lunches served at the workplace, consisting of (1 animal-based foods; (2 plant-based foods; and (3 both animal-based and plant-based foods. Employees of the National Institute for Public Health and the Environment in the Netherlands participated in the study. Participants scored the lunch for appreciation and tastiness (scores from 1 to 10. Greenhouse gas (GHG emissions and land use associated with foods consumed were calculated using life cycle assessments. Nutrient intake was calculated using food composition data. The results show that both the plant-based and the combination lunch received higher scores for tastiness than the animal-based lunch. GHG emissions and land use were lowest for the plant-based lunch and highest for the animal-based lunch. The combination lunch was associated with increased fiber and decreased saturated fat intake compared to the animal-based lunch, but also lead to increased energy intake. The plant-based lunch did not increase energy intake, while increasing fiber intake and decreasing sodium (salt and saturated fat intakes. These initial results show that plant-based lunches have the potential to improve nutrient intake and tastiness while reducing environmental impact. Additional research in this field is worthwhile.

Healthier Standards for School Meals and Snacks: Impact on School Food Revenues and Lunch Participation Rates.

In 2012, the updated U.S. Department of Agriculture school meals standards and a competitive food law similar to the fully implemented version of the national Smart Snack standards went into effect in Massachusetts. This study evaluated the impact of these updated school meal standards and Massachusetts' comprehensive competitive food standards on school food revenues and school lunch participation. Revenue and participation data from 11 Massachusetts school districts were collected from 2011 to 2014 and analyzed in 2015 using multilevel modeling. The association between the change in compliance with the competitive food standards and revenues/participation was assessed using linear regression. Schools experienced declines in school food revenues of $15.40/student in Year 1 from baseline (p=0.05), due to competitive food revenue losses. In schools with 3 years of data, overall revenues rebounded by the second year post-implementation. Additionally, by Year 2, school lunch participation increased by 15% (p=0.0006) among children eligible for reduced-price meals. Better competitive food compliance was inversely associated with school food revenues in the first year only; an absolute change in compliance by 10% was associated with a $9.78/student decrease in food revenues over the entire school year (p=0.04). No association was seen between the change in compliance and school meal participation. Schools experienced initial revenue losses after implementation of the standards, yet longer-term school food revenues were not impacted and school meal participation increased among children eligible for reduced-price meals. Weakening the school meal or competitive food guidelines based on revenue concerns appears unwarranted. Copyright © 2016 American Journal of Preventive Medicine. Published by Elsevier Inc.

Many schools have recently adopted food policies and replaced unhealthy products by healthy foods. Consequently, adolescents are more likely to consume a healthy meal if they stay in school for lunch to eat a meal either prepared at home or purchased in school cafeterias. However, many continue to eat in nearby fast-food restaurants. The present paper describes the development of a theory-based intervention programme aimed at encouraging high school students to stay in school for lunch. Intervention Mapping and the Theory of Planned Behaviour served as theoretical frameworks to guide the development of a 12-week intervention programme of activities addressing intention, descriptive norm, perceived behavioural control and attitude. It was offered to students and their parents with several practical applications, such as structural environmental changes, and educational activities, such as audio and electronic messages, posters, cooking sessions, pamphlets, improvisation play theatre, quiz, and conferences. The programme considers theoretical and empirical data, taking into account specific beliefs and contexts of the target population. This paper should help programme planners in the development of appropriate interventions addressing the problem. Copyright © 2012 Elsevier Ltd. All rights reserved.

Children's dietary intake is a key variable in evaluations of school-based interventions. Current methods for assessing children's intake, such as 24-hour recalls and meal observations, are time- and resource-intensive. As part of a study to evaluate the impact of farm-to-school programs, the school lunch recall was developed from a need for a valid and efficient tool to assess school lunch intake among large samples of children. A self-administered paper-and-pencil questionnaire, the school lunch recall prompts for school lunch items by asking children whether they chose a menu item, how much of it they ate, how much they liked it, and whether they would choose it again. The school lunch recall was validated during summer school in 2008 with 18 third- to fifth-grade students (8 to 11 years old) in a North Carolina elementary school. For 4 consecutive days, trained observers recorded foods and amounts students ate during school lunch. Students completed the school lunch recall immediately after lunch. Thirty-seven total observation school lunch recall sets were analyzed. Comparison of school lunch recalls against observations indicated high accuracy, with means of 6% for omission rate (items observed but unreported), 10% for intrusion rate (items unobserved but reported), and 0.63 servings for total inaccuracy (a measure that combines errors for reporting items and amounts). For amounts, accuracy was high for matches (0.06 and 0.01 servings for absolute and arithmetic differences, respectively) but lower for omissions (0.47 servings) and intrusions (0.54 servings). In this pilot study, the school lunch recall was a valid, efficient tool for assessing school lunch intake for a small sample of third- to fifth-grade students.

In 2005, the nutritional content of children's school lunches in England was widely criticised, leading to a major policy change in 2006. Food and nutrient-based standards were reintroduced requiring primary schools to comply by September 2008. We aimed to determine the effect of the policy on the nutritional content at lunchtime and in children's total diet. We undertook a natural experimental evaluation, analysing data from cross-sectional surveys in 12 primary schools in North East England, pre and post policy. Dietary data were collected on four consecutive days from children aged 4-7 years (n = 385 in 2003-4; n = 632 in 2008-9). We used linear mixed effect models to analyse the effects of gender, year, and lunch type on children's mean total daily intake. Both pre- and post-implementation, children who ate a school lunch consumed less sodium (mean change -128 mg, 95% CI: -183 to -73 mg) in their total diet than children eating home-packed lunches. Post-implementation, children eating school lunches consumed a lower % energy from fat (-1.8%, -2.8 to -0.9) and saturated fat (-1.0%; -1.6 to -0.5) than children eating packed lunches. Children eating school lunches post implementation consumed significantly more carbohydrate (16.4 g, 5.3 to 27.6), protein (3.6 g, 1.1 to 6.0), non-starch polysaccharides (1.5 g, 0.5 to 1.9), vitamin C (0.7 mg, 0.6 to 0.8), and folate (12.3 µg, 9.7 to 20.4) in their total diet than children eating packed lunches. Implementation of school food policy standards was associated with significant improvements in the nutritional content of school lunches; this was reflected in children's total diet. School food- and nutrient-based standards can play an important role in promoting dietary health and may contribute to tackling childhood obesity. Similar policy measures should be considered for other environments influencing children's diet.

Both pre- and post-implementation, children who ate a school lunch consumed less sodium (mean change -128 mg, 95% CI: -183 to -73 mg in their total diet than children eating home-packed lunches. Post-implementation, children eating school lunches consumed a lower % energy from fat (-1.8%, -2.8 to -0.9 and saturated fat (-1.0%; -1.6 to -0.5 than children eating packed lunches. Children eating school lunches post implementation consumed significantly more carbohydrate (16.4 g, 5.3 to 27.6, protein (3.6 g, 1.1 to 6.0, non-starch polysaccharides (1.5 g, 0.5 to 1.9, vitamin C (0.7 mg, 0.6 to 0.8, and folate (12.3 µg, 9.7 to 20.4 in their total diet than children eating packed lunches. Implementation of school food policy standards was associated with significant improvements in the nutritional content of school lunches; this was reflected in children's total diet. School food- and nutrient-based standards can play an important role in promoting dietary health and may contribute to tackling childhood obesity. Similar policy measures should be considered for other environments influencing children's diet.

To explore how the quality of school lunch consumed reflected overall eating patterns in school-aged children. Children filled in an Internet-based questionnaire about their eating patterns. The children were then divided into balanced and imbalanced school lunch eaters on the basis of their responses in the questionnaire. A balanced school lunch consisted of, by the definition used in the present study, a main dish, salad and bread. Eleven primary schools and one middle school in eastern Finland. A total of 531 schoolchildren (247 boys and 284 girls) aged 11-16 years. The school lunch was balanced in 46·5% of children. Eating a balanced school lunch was associated with overall healthier eating patterns outside school. Children who ate a balanced school lunch had more regular meal times and consumed healthier snacks. They ate fruit or berries and vegetables, dairy products and wholegrain foods more often, consumed fewer salty snacks, pizzas, meat pies and drank fewer soft drinks and energy drinks. Their eating patterns at home were also healthier, with vegetables being offered at every family dinner and fruit being offered daily, whereas soft drinks were offered seldom. The choices made by children in their school lunch reflect the overall eating patterns among school-aged children. Eating a balanced school lunch is associated with more regular meal patterns, the availability of healthier foods at home and an overall healthier diet, suggesting that healthy eating patterns are learnt at home.

Plate Waste in School Lunch Programs in Beijing, China

Full Text Available School plate waste is of particular concern worldwide due to its adverse impacts not only on resource use and the environment, but also on students’ health, physical maturation, and academic achievement in the long term. Previous studies on school plate waste have all been conducted in industrialized countries, and more studies are badly needed in developing countries. In this paper, we report a pilot study on the patterns and causes of plate waste in school lunch programs in Beijing, China, by a combination of physical weighing, questionnaire survey, and semi-structured interview approaches. Our results show that the average amount of food waste generated by school students in Beijing in 2014 was 130 g/cap/meal, accounting for 21% of total food served. Staple food (43% and vegetables (42% were the dominant proportions. Buffet meals resulted in less plate waste than packed meals and set meals. Food supply patterns, the quality of canteen service, and the dietary habit and students’ knowledge of food production were the main influencing factors behind plate waste. To our best knowledge, our pilot study provides a first understanding of the overlooked plate waste in school lunch programs in China, and a good basis for further analysis in this field, and will be helpful in informing policy-making in relevant nutrition and education programs in schools in China.

We aimed to develop a cost-free and sustainable program to influence healthier eating decisions during elementary school lunch. Baseline food and beverage choices were assessed for 9 days during lunch service at two racially and economically diverse elementary schools in Spartanburg County, SC, USA. After being informed that the labeled items on the daily lunch menu represented the healthiest choice, students were allowed to ring a call bell in the cafeteria for public recognition when they chose all of the identified healthiest food and beverage items during lunch service. Using menus matched to the baseline phase, food and beverage choices were measured during a 9-day intervention phase. After 30 days, food and beverage choices were reassessed during a 3-day follow-up phase. Healthiest food & beverage choices increased 49% with >60% of students choosing non-flavored milk over flavored milk during the intervention phase. There was no difference in the success of the program between the two schools. The program continued and healthy eating decisions were significantly sustained at a 30-day follow-up assessment. Public recognition through bell ringing appears to be an effective practice to sustain increases in healthy eating decisions during elementary school lunch and warrants expansion to larger scale, longitudinal trials.

Levitsky, David A; Pacanowski, Carly

2011-10-01

High-protein liquid meal replacements have proven to be effective in reducing caloric intake and body weight. Recently, substituting high fiber breakfast cereals for the more expensive high-protein drinks has been found to be equally effective to reduce weight. The following study tested the hypothesis that the mechanism responsible for the reduced intake was not the dietary composition of the meal replacement, but the controlled portion sized meals. Seventeen volunteers ate all of their meals and snacks from foods provided by the research unit from Monday to Friday for five consecutive weeks. For the first week, all participants selected their food from a buffet where each food was weighed before and after eating. For the next two weeks, half of the group selected their lunch by choosing one food from a selection of six commercially available portion controlled foods. They could eat as much as they wished at other meals or snacks. For final weeks four and five, the conditions were reversed for the two groups. Consuming the portion controlled lunches resulted in about a 250 kcal reduction in energy intake. More importantly, no sign of caloric compensation was evident across the 10 days of testing, an observation substantiated by a significant loss of body weight. The results suggest that the mere substitution of one smaller portioned meal each day is sufficient to cause reduction in daily energy intake and a significant amount of weight.

Data from the ongoing, open-cohort Dortmund Nutritional and Anthropometric Longitudinally Designed (DONALD) study were used to describe warm family lunch meals and the association of the lunch composition with total diet quality. 2,095 three-day weighed dietary records, collected between 2004 and 2009, from a 4- to 18-year-old DONALD study subgroup were used. Warm lunch (eating occasions between 11.30 a.m. and 2.29 p.m. including at least one course that is typically consumed warm) was eaten on 68.8% of all record days. Meat lunch (>50%) was predominant, followed by vegetarian (25%), fish (13%) and sweet lunch meals (3%). The prevalence of desserts at lunch was high and beverages were drunk at 80% of lunch meals. A meat lunch was associated with a higher protein (+1.4% energy intake, %E) and fat intake (+1.7%E) than a sweet lunch; also densities of vitamin A, folate and iron were higher. A dessert at lunch decreased protein intake slightly (-0.2%E), but increased carbohydrate (+0.7%E) and added sugar intake (+1.4%E) as well as density of calcium (+18 mg/MJ). Our study proves the impact of lunch on daily dietary quality and yields valuable insights on the development of food and meal-based dietary guidelines. Copyright © 2012 S. Karger AG, Basel.

To (i) evaluate food choices and consumption patterns of elementary- and middle-school students who participate in the National School Lunch Program (NSLP) and (ii) compare students' average nutrient intake from lunch with NSLP standards. Plate waste from elementary- and middle-school students' lunch trays was measured in autumn 2010 using a previously validated digital photography method. Percentage waste was estimated to the nearest 10 % for the entrée, canned fruit, fresh fruit, vegetable, grain and milk. Univariate ANOVA determined differences in percentage waste between schools, grades and genders. Daily nutrient intake was calculated using the district's menu analysis and percentage waste. Elementary and middle schools in northern Colorado (USA). Students, grades 1-8. Plate waste was estimated from 899 lunch trays; 535 elementary- and 364 middle-school students. Only 45 % of elementary- and 34 % middle-school students selected a vegetable. Elementary-school students wasted more than a third of grain, fruit and vegetable menu items. Middle-school students left nearly 50 % of fresh fruit, 37 % of canned fruit and nearly a third of vegetables unconsumed. Less than half of the students met the national meal standards for vitamins A and C, or Fe. Few students' lunch consumption met previous or new, strengthened NSLP lunch standards. Due to the relatively low intake of vegetables, intakes of vitamins A and C were of particular concern. Effective behavioural interventions, combined with marketing, communications and behavioural economics, will likely be necessary to encourage increased vegetable intake to meet the new meal standards.

The aim of the study was to determine whether plate size affects ad libitum energy intake (EI) at a buffet-style lunch in overweight, yet unrestrained women. Twenty overweight/obese (BMI=25-40 kg/m(2)) women attended two study visits, and were randomly assigned to small (19.5 cm) or large (26.5 cm) diameter plate size at a free choice lunch meal. At 9 am participants were given a small (0.5 MJ) breakfast, followed at 12 noon by the lunch meal from which they ate ad lib until comfortably full. Mean (SEM) EI at lunch was 3975 (239)kJ and 3901 (249) kJ respectively for small and large plate size. There was no detectable difference in EI between the two plate sizes (P>0.05). When in a raised state of hunger and offered a palatable buffet meal, altering the diameter of the dining plate onto which food was self-served did not significantly alter ad lib EI. We conclude there was no evidence that a smaller plate suppressed EI in a group of unrestrained, overweight women encouraged to eat to appetite from a wide choice of items. Whether plate size is a useful cue for portion size, and hence control of EI, in individuals actively restricting intake however remains possible, and requires investigation.

2011-01-28

Past research has shown that promotional messages such as food advertising influence food consumption. However, what has gone largely unexplored is the effect of exercise advertising on food intake. This study experimentally tested the effects of exposure to exercise commercials on food intake at a lunch meal as compared to the effects of control commercials. Prior to eating lunch, 125 participants (71 women, 54 men) watched 8 commercials, either all related to exercise or fitness (n=67) or neutral products (i.e. car insurance) (n=58). The meal consisted of a pasta dish with tomato sauce, salad and chocolate pudding. The post-lunch questionnaire included questions about body mass index, exercise habits, motivation and dietary restraint. Participants exposed to exercise commercials reduced their caloric intake by 21.7% relative to the control condition. Additionally, watching exercise messages increased the perceived healthiness and liking of the meal. Although exercise habits and intentions did not moderate the effect of commercial condition on food intake, we also found that this intake reduction was driven by participants with higher body mass index levels. These results imply that exercise messages may serve as a reminder of the link between food and physical activity and affect food consumption. It also highlights the need for increased awareness that these messages have powerful influences not only on exercise behavior, but also on closely related behaviors such as eating.

School lunch waste among middle school students: nutrients consumed and costs.

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.

The purpose of this study is to examine the impact of a districtwide food best practices and preparation changes in elementary schools lunches, implemented as part of the LiveWell@School childhood obesity program, funded by LiveWell Colorado/Kaiser Permanente Community Health Initiative. Longitudinal study examining how school changes in best practices for food preparation impacted the types of side items offered from 2009 to 2015 in elementary school cafeterias in a high-need school district in southern Colorado. Specifically, this study examined changes in side items (fruits, vegetables, potatoes, breads, and desserts). In Phase 1 (2009-2010), baseline data were collected. During Phase 2 (2010-2011), breaded and processed foods (e.g., frozen nuggets, pre-packaged pizza) were removed and school chefs were trained on scratch cooking methods. Phase 3 (2011-2012) saw an increased use of fresh/frozen fruits and vegetables after a new commodity order. During Phase 4 (2013-2015), chef consulting and training took place. The frequency of side offerings was tracked across phases. Analyses were completed in Fall 2016. Because of limited sample sizes, data from Phases 2 to 4 (intervention phases) were combined for potatoes and desserts. Descriptive statistics were calculated. After adjusting for length of time for each phase, Pearson chi-square tests were conducted to examine changes in offerings of side items by phase. Fresh fruit offerings increased and canned fruit decreased in Phases 1-4 (p=0.001). A significant difference was observed for vegetables (p=0.001), with raw and steamed vegetables increasing and canned vegetables decreasing from Phase 1 to 4. Fresh potatoes (low in sodium) increased and fried potatoes (high in sodium) decreased from Phase 1 to Phases 2-4 (p=0.001). Breads were eliminated entirely in Phase 2, and dessert changes were not significant (p=0.927). This approach to promoting healthier lunch sides is a promising paradigm for improving elementary

To compare the fat and cholesterol content of the foods offered and selected in an elementary school lunch program with current dietary guidelines. For 105 school days we recorded the food items selected by elementary school students in an entire school district (262,851 meals) who were given a choice between two entrees. The nutrient content of foods was assessed with a computerized nutrient data base supplemented by the food manufacturers' data. Sixteen elementary schools in the Bellevue (Washington) School District. The number of students eating school lunch averaged 2500 per day, of whom 25% were from households with incomes less than 185% of poverty. None. We determined the nutritional content of the average meal selected; the proportion of days when one of the two offered entrees met fat and cholesterol guidelines; and the proportion of children selecting the entrees that met the guidelines. The average lunch selected had 35.9% of calories from total fat and 12.6% from saturated fat, exceeding the guidelines of 30% and 10%, respectively. Lunch contained an average of 57 mg cholesterol (106 mg/1000 kcal) and met guidelines. One of the two daily entree choices met guidelines for both total fat and saturated fat on 20% of days, and met both fat and cholesterol guidelines on 14% of days. When available, entrees meeting the fat guidelines were chosen by 37% of students, and entrees meeting both fat and cholesterol guidelines were chosen by 34% of students. In this school district the average lunch selected did not meet the current guidelines for dietary fat; when given the choice, more than one third of students selected the entrees that met these guidelines.

An estimated 40% of children bring a packed lunch to school. These lunches are not required to meet nutrition standards. The aim of this study was to compare differences in the nutritional quality of elementary packed lunches by the presence or absence of sugar-sweetened beverages (SSB), desserts, and fruits and vegetables (FVs). Observational data for prekindergarten and kindergarten packed lunches were collected from three schools in rural Virginia for 5 consecutive school days and analyzed for macro- and micronutrients and by the presence or absence of food and beverage items. Of the 561 packed lunch observations collected, 41.7% contained no FV, 41.2% contained an SSB, and 61.1% contained a dessert. The nutrient profile of packed lunches with at least one fruit or vegetable had significantly higher levels of carbohydrate, fiber, sugar, vitamin A, and vitamin C. Packed lunches containing an SSB had significantly higher levels of sugar and vitamin C and significantly lower levels of protein, fiber, vitamin A, calcium, and iron. Packed lunches containing a dessert had significantly higher levels of energy, carbohydrate, fat, saturated fat, sodium, sugar, vitamin C, and iron and significantly lower levels of vitamin A. Additional research is needed to fully understand parent and child motivations for packing lunches and the decision processes that influence the inclusion of food items. The development of packed lunch interventions, encouragement of National School Lunch Program participation, or enactment of school policies to increase the nutritional value of packed lunches is warranted.

2018-02-01

Visual aids, such as food photographs, are widely used in estimating food quantities in dietary surveys. The present study aimed to assess how accurately Danish adults and children can estimate food portion sizes using 37 series of photographs illustrating four to six different portion sizes under real-life conditions; determine whether adults were more accurate than children; and estimate the error caused by using portion size photographs to estimate weights of foods consumed in macronutrient calculation. Six hundred and twenty-two adults and 109 children were recruited in three workplace canteens and in two schools, respectively, to estimate their lunchtime portions based on photographs. Participants were instructed to keep the foods separated on their plate when taking lunch. Participants thereafter estimated their own portions by looking at the relevant series of photographs. The actual food portions were then weighed. The proportion of correct estimations was 42% overall (range 19-77%). The mean difference (%) between estimated and actual weight was 17% (range 1-111%). Small portion size photographs were more often used correctly compared to larger portion photographs. Children had as many correct estimations as adults, although they overestimated portions more. Participants using fractions of (or more than) one photograph to estimate the portion of a food had significantly larger errors. When calculating the macronutrient content of a weekly menu using the estimated portion sizes, protein had the largest error (29%). When used in a real-life situation, the portion size photographs validated in the present study showed a certain inaccuracy compared to the actual weights. © 2017 The British Dietetic Association Ltd.

Full Text Available The objective of this study was to assess the quality of lunch consumed by adults in Brazil and its sociodemographic determinants in each Brazilian region. A cross-sectional study was carried out and a representative sample of regional populations was used. The sample comprised of 16,096 adults from the Brazilian National Dietary Survey, part of the Brazilian Household Budget Survey (POF. The lunch quality was evaluated by applying the main meal quality index (MMQI, comprised of 10 items of equal weights that resulted in a score that ranged from zero to 100 points. Linear regression models measured the association between lunch quality and sociodemographic factors. The average energy consumption at lunch was 704kcal (SD = 300, and the meal quality score mean was 57 points (SE = 0.30. The North Region had the worst MMQI score (56 points, SE = 0.07, while the Central had the best MMQI adjusted score (59 points, SE = 0.05. The MMQI final score was positively associated with male gender and ages between 20-39 years, and was inversely associated with having eight years or more of education, per capita income of at least three minimum wages, and with the consumption of meals prepared away from home. Despite differences among sociodemographic factors, all Brazilian regions had a lunch composed of foods rich in sugars and fats, with insufficient portions of fruits and vegetables, resulting in a low meal quality.

Full Text Available School environments influence student food choices. À la carte foods and beverages are often low nutrient and energy dense. This study assessed how much money students spent for these foods, and the total kilocalories purchased per student during the 2012–2013 school year. Six elementary and four intermediate schools in the Houston area provided daily food purchase transaction data, and the cost and the calories for each item. Chi-square analysis assessed differences in the number of students purchasing à la carte items by grade level and school free/reduced-price meal (FRP eligibility. Analysis of covariance assessed grade level differences in cost and calories of weekly purchases, controlling for FRP eligibility. Intermediate grade students spent significantly more on à la carte food purchases and purchased more calories (both p < 0.001 than elementary school students. Lower socioeconomic status (SES elementary and intermediate school students purchased fewer à la carte foods compared to those in higher SES schools (p < 0.001. Intermediate school students purchased more à la carte foods and calories from à la carte foods than elementary students. Whether the new competitive food rules in schools improve student food selection and purchase, and dietary intake habits across all grade levels remains unknown.

There is limited evidence on how diet changes over the transition from primary to secondary school. In this study we investigated changes in diet from age 10 (2007) to age 14 years (2011) and the contribution of school-time consumption and school lunch choice to such changes. The 351 participants with dietary data (4 day food record) available at baseline (age 10 years) and follow-up (age 14 years) were included. Multi-level regression models were fitted for absolute or change in food and nutrient intake, cross-classified by primary and secondary school attended as appropriate, with adjustment for covariates and mis-reporting. From age 10 to age 14 years, children decreased energy intake from sugars (-2.6% energy (%E)) (standard error (SE) 0.44) and from saturated fats (-0.54%E (SE 0.18)), decreased fruit (-3.13 g/MJ (SE 1.04)) and vegetables (-1.55 g/MJ (SE 0.46)) consumption and increased sugar sweetened beverage (SSB) (4.66  g/MJ (SE 1.87)) and fries (1.31  g/MJ (SE 0.39)) consumption. Intake of snack foods, SSBs, and fries, but also fruits and vegetables was higher outside school hours. Prospective change from non-school lunch to school lunch, compared to maintaining non-school lunch consumption, was associated with decreased consumption of savoury snacks (-8.32 g/day (SE 2.03)), increased consumption of fries (12.8 g/day (SE 4.01)) and decreased consumption of fruit (-25.16 g/day (SE 11.02)) during school hours. Changes in diet from age 10 to age 14 years differed within and outside of school hours. Consumption of a school lunch, compared to lunch obtained elsewhere, was associated with negative as well as positive changes in diet, suggesting that any efforts to encourage school lunch take-up need to be accompanied by further efforts to improve school lunch provision to meet nutritional guidelines.

1990-12-01

Two groups of three subjects participated in a residential study that assessed the effects of varying the macronutrient and caloric content of a required lunch meal on subsequent food choice and intake. Lunches contained 431 or 844 kcal, with the caloric differential created by manipulating the calories derived from either fat or carbohydrate (CHO). Each lunch condition (high-fat, high-CHO, low-fat, and low-CHO) was examined for 3 consecutive days. Subjects controlled their own patterns of food intake and could consume any item or number of items at any time during the day or night. There were no significant differences in total daily caloric intake across conditions, indicating that subjects compensated for the caloric content of the lunch regardless of the macronutrient content. Total daily caloric intake under the high-fat and high-CHO conditions was 2824 +/- 151 (mean +/- SEM) and 2988 +/- 187 kcal, respectively, whereas intake under the low-fat and low-CHO conditions was 2700 +/- 131 and 2890 +/- 247 kcal, respectively.

Few studies have assessed the dietary quality of children who eat meals from home compared with school meals according to the 2010 Dietary Guidelines for Americans. The objective of this study was to examine diet quality for elementary school students in relation to source of breakfast and lunch (whether school meal or from an outside source). An observational study was conducted of students in 43 schools in San Diego, CA, during the 2011-2012 school year. Fourth- and fifth-grade students (N=3,944) completed a diary-assisted 24-hour food recall. The Healthy Eating Index-2010 (HEI-2010) scores of children who ate breakfast and lunch at school were compared with the HEI-2010 scores of children who obtained their meals from home and a combination of both school and home. Analysis of variance, χ 2 test, and generalized estimating equation models adjusted for age, sex, race/ethnicity, grade, language, and school level clustering were performed. School lunch eaters had a higher mean±standard deviation overall diet quality score (HEI-2010=49.0±11.3) compared with students who ate a lunch obtained from home (46.1±12.2; P=0.02). There was no difference in overall diet quality score by breakfast groups. Students who ate school breakfast had higher total fruit (P=0.01) and whole fruit (P=0.0008) scores compared with students who only ate breakfast obtained from home. Students who ate school foods had higher scores for dairy (P=0.007 for breakfast and Pempty calories from solid fats and added sugars (P=0.01 for breakfast and P=0.007 for lunch). Eating school lunch was associated with higher overall diet quality compared with obtaining lunch from home. Future studies are needed that assess the influence of the Healthy Hunger-Free Kids Act on children's diet quality. Copyright © 2016 Academy of Nutrition and Dietetics. Published by Elsevier Inc.

Full Text Available Modifying the school food environment is on the national agenda as one strategy to improve the nutritional quality of children’s diets. Because few environmental-level interventions have been rigorously evaluated, the evidence base to inform programs and policies is limited. Of concern is the impact that changes to cafeteria offerings will have on participation in school meal programs. This study evaluates school lunch participation in the setting of a year-long middle school cafeteria intervention by examining the association between body mass index (BMI, sociodemographics, and the purchases of school lunch meals. IMOVE meals were healthier choices that met stringent nutritional criteria and were offered alongside standard lunch meals. Students who were overweight had a significantly higher purchase rate for both types of meals compared to those with a healthy BMI. Non-white race, younger age, being male, and low-income status were also significantly associated with participation in school lunch. Results indicate that nutritionally vulnerable students participate in school lunch and are equally likely to buy healthy alternatives or standard meals. This behavioral observation has important implications for school foodservice programs and policies. These results are timely given recent federal legislation to improve the school food environment to influence students’ food choice behaviors.

Collins, Rebecca; Stafford, Lorenzo D

2015-01-01

Separate lines of research have demonstrated the role of mood and memory in the amount of food we consume. However, no work has examined these factors in a single study and given their combined effects beyond food research, this would seem important. In this study, the interactive effect of these factors was investigated. Unrestrained female participants (n = 64) were randomly assigned to either a positive or neutral mood induction, and were subject to a lunch cue (recalling their previously eaten meal) or no lunch cue, followed by a snack taste/intake test. We found that in line with prediction that food intake was lower in the lunch cue versus no cue condition and in contrast, food intake was higher in the positive versus neutral mood condition. We also found that more food was consumed in the lunch cue/positive mood compared to lunch cue/neutral mood condition. This suggests that positive mood places additional demands on attentional resources and thereby reduces the inhibitory effect of memory on food consumption. These findings confirm that memory cue and positive mood exert opposing effects on food consumption and highlight the importance of both factors in weight control interventions.

Previous studies have suggested that young children are inaccurate reporters of dietary intake. The purpose of this study was to validate a single recall of the previous day's school lunch reported by 6-8 year old Swedish children and to assess teacher-recorded intake of the same meal in a standardized food journal. An additional research question was whether parents could report their child's intake of the previous day's lunch. Subjects constituted a convenience sample from the large, multi-country study Identification and prevention of Dietary- and lifestyle-induced health EFfects In Children and infantS (IDEFICS). Validations of both children's recalls and teachers' records were made by comparing results with the duplicate plate reference method. Twenty-five children (12 boys/13 girls) aged 6-8 years participated in the validation study at one school in western Sweden. Children were accurate self-reporters of their dietary intake at lunch, with no significant difference between reported and weighed intake (Mean difference (SD): 7(50) kcals, p=0.49). Teachers significantly over-reported intake (Mean difference (SD): 65(79) kcals, p=0.01). For both methods, child-reported and teacher-recorded, correlations with weighed intake were strong (Pearson's correlations r=0.92, pteacher-records and weighed intakes. Foods were recalled by children with a food-match rate of 90%. In all cases parents themselves were unable to report on quantities consumed and only four of 25 children had parents with knowledge regarding food items consumed. Children 6-8 years of age accurately recalled their school lunch intake for one occasion while teachers recorded with less accuracy. Our findings suggest that children as young as six years of age may be better able to report on their dietary intake than previously suggested, at least for one main meal at school. Teacher-recorded intake provides a satisfactory estimate but with greater systematic deviation from the weighed intake

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.

Full Text Available Background: The establishment of staff canteens is expected to improve the nutritional situation of Cambodian garment workers. The objective of this study is to assess the nutritive value of low-price model lunch sets provided at a garment factory in Phnom Penh, Cambodia. Methods: Exemplary lunch sets were served to female workers through a temporary canteen at a garment factory in Phnom Penh. Dish samples were collected repeatedly to examine mean serving sizes of individual ingredients. Food composition tables and NutriSurvey software were used to assess mean amounts and contributions to recommended dietary allowances (RDAs or adequate intake of energy, macronutrients, dietary fiber, vitamin C (VitC, iron, vitamin A (VitA, folate and vitamin B12 (VitB12. Results: On average, lunch sets provided roughly one third of RDA or adequate intake of energy, carbohydrates, fat and dietary fiber. Contribution to RDA of protein was high (46% RDA. The sets contained a high mean share of VitC (159% RDA, VitA (66% RDA, and folate (44% RDA, but were low in VitB12 (29% RDA and iron (20% RDA. Conclusions: Overall, lunches satisfied recommendations of caloric content and macronutrient composition. Sets on average contained a beneficial amount of VitC, VitA and folate. Adjustments are needed for a higher iron content. Alternative iron-rich foods are expected to be better suited, compared to increasing portions of costly meat/fish components. Lunch provision at Cambodian garment factories holds the potential to improve food security of workers, approximately at costs of <1 USD/person/day at large scale. Data on quantitative total dietary intake as well as physical activity among workers are needed to further optimize the concept of staff canteens.

Obtaining valid and reliable estimates of usual dietary intake at a reasonable cost is a challenge in school-based nutrition research. The Automated Self-Administered 24-Hour Dietary Recall for Children, 2014 version (ASA24 Kids-2014), a self-administered, computerized 24-hour dietary recall, offers improved feasibility over traditional interviewer-administered 24-hour recalls. This mixed-methods study examined ASA24 Kids-2014's validity for measuring dietary intake from National School Lunch Program lunches. After 24% attrition, 96 middle-school students from three urban schools in eastern Pennsylvania participated in the study. A subsample of 27 participants completed qualitative interviews. Data were collected in the spring of 2014. Self-reported ASA24 Kids-2014 data were compared to direct observations of school lunch, which served as the criterion measure. Dependent variables included eight meal components selected from the National School Lunch Program guidelines (fruit, vegetables, grains, protein-rich foods, dairy, oils, solid fats, and added sugars). A supplemental interview collected qualitative data regarding students' perceptions of content and substantive validity. The Wilcoxon signed rank test and Spearman's ρ examined criterion-related validity; qualitative content analysis examined content and substantive validity. Participants inaccurately recalled food items eaten at lunch, as 58% of foods were reported in error. However, among foods recalled correctly, no statistically significant differences emerged for estimates of portions consumed for six meal components (fruit, vegetables, grains, protein-rich foods, oils, and added sugars). In addition, statistically significant positive correlations emerged between ASA24 Kids-2014 and direct observation for all estimates. Qualitative data identified students' interest and motivation, comprehension, memory, and English-language fluency as relevant sources of error. Middle school students have difficulty

Living alone but eating together: Exploring lunch clubs as a dining out experience.

Dining out is most often associated with pleasure and gratification, principally since it presents opportunities for sociability. However, access to dining out experiences is influenced by multiple factors, including age. Little is known about the dining out habits of older people. In particular, the food practices of those living alone in the community is under-researched compared to those in hospital or residential care. This study explores the perceptions and preferences of ten older people towards domestic and communal meals in South East Scotland. Qualitative data were generated from 5-day food diaries and in-depth interviews with individuals who lived alone and attended a community-based senior citizen's lunch club. Data were coded and thematically analysed using a symbolic interactionist perspective. A number of key themes were identified, including the meaning of mealtimes. It was found that most participants ate the majority of their meals at home alone. Despite this, dining alone was not necessarily experienced as 'lonely'. Participants reported that dining out at the lunch club was a pleasurable experience given the social interaction and the separation of consumption from food work. Moreover, due to restricted mobility and limited access to transport, the lunch club was viewed by participants as one of the few places that they could go to dine out. Copyright © 2017.

Effects of awareness that food intake is being measured by a universal eating monitor on the consumption of a pasta lunch and a cookie snack in healthy female volunteers☆

Thomas, J.M.; Dourish, C.T.; Higgs, S.

2015-01-01

To date, there have been no studies that have explicitly examined the effect of awareness on the consumption of food from a Universal Eating Monitor (UEM – hidden balance interfaced to a computer which covertly records eating behaviour). We tested whether awareness of a UEM affected consumption of a pasta lunch and a cookie snack. 39 female participants were randomly assigned to either an aware or unaware condition. After being informed of the presence of the UEM (aware) or not being told about its presence (unaware), participants consumed ad-libitum a pasta lunch from the UEM followed by a cookie snack. Awareness of the UEM did not significantly affect the amount of pasta or cookies eaten. However, awareness significantly reduced the rate of cookie consumption. These results suggest that awareness of being monitored by the UEM has no effect on the consumption of a pasta meal, but does influence the consumption of a cookie snack in the absence of hunger. Hence, energy dense snack foods consumed after a meal may be more susceptible to awareness of monitoring than staple food items. PMID:26048004

Forty-one percent of elementary schoolchildren bring lunch to school on any given day. Fortyfive percent bring snacks. Surprisingly, little is known about the foods and beverages they bring. The present cross-sectional analysis of baseline data from the GREEN Project Lunch Box Study sought to: (1) characterize foods and beverages brought from home to school by elementary schoolchildren, and (2) compare the quality of packed lunches to National School Lunch Program (NSLP) standards and packed snacks to Child and Adult Care Food Program (CACFP) requirements. Lunches and snacks from 626 elementary schoolchildren were assessed and evaluated using digital photography and a supplemental food checklist. Food and beverage types most likely to be provided for lunch were sandwiches (59%), snackfoods (42%), fruit (34%), desserts (28%), water (28%) and sugar-sweetened beverages (24%). Twenty-seven percent of lunches met at least three of five NSLP standards. At snack, snackfoods (62%), desserts (35%) and sugar-sweetened beverages (35%) were more common than fruits (30%), dairy foods (10%), and vegetables (3%). Only 4% of snacks met two of four CACFP standards. Future research is needed to understand the multiple determinants of food packing behavior, including constraints faced by families. School wellness policies should consider initiatives that work collaboratively with parents to improve the quality of foods brought from home. PMID:25037557

Processed foods are major contributors to excessive sodium intake in Western populations. We investigated the effect of food reformulation on daily dietary sodium intake. To determine whether uninformed consumers accept reduced-sodium lunches and to determine the effect of consuming reduced-sodium lunches on 24-hour urinary sodium excretion. A single-blind randomized controlled pretest-posttest design with two parallel treatment groups was used. Participants chose foods in an experimental real-life canteen setting at the Restaurant of the Future in Wageningen, the Netherlands, from May 16 until July 1, 2011. After a run-in period with regular foods for both groups, the intervention group (n=36) consumed foods with 29% to 61% sodium reduction (some were partially flavor compensated). The control group (n=38) continued consuming regular foods. Outcomes for assessment of acceptance were the amount of foods consumed, energy and sodium intake, remembered food liking, and intensity of sensory aspects. Influence on daily dietary sodium intake was assessed by 24-hour urinary sodium excretion. Between and within-subject comparisons were assessed by analysis of covariance. Energy intake and amount consumed of each food category per lunch remained similar for both groups. Compared with the control group, the intervention group's sodium intake per lunch was significantly reduced by -1,093 mg (adjusted difference) (95% CI -1,285 to -901), equivalent to 43 mmol sodium. Remembered food liking, taste intensity, and saltiness were scored similarly for almost all of the reduced-sodium foods compared with the regular foods. After consuming reduced-sodium lunches, compared with the control group, intervention participants' 24-hour urinary sodium excretion was significantly lower by -40 mEq (adjusted difference) (95% CI -63 to -16) than after consuming regular lunches, and this reflects a decreased daily sodium intake of 1 g. Comparing the two treatment groups, consumption of reduced

Previous research has shown that oral processing characteristics like bite size and oral residence duration are related to the satiating efficiency of foods. Oral processing characteristics are influenced by food texture. Very little research has been done on the effect of food texture within solid foods on energy intake. The first objective was to investigate the effect of hardness of food on energy intake at lunch, and to link this effect to differences in food oral processing characteristics. The second objective was to investigate whether the reduction in energy intake at lunch will be compensated for in the subsequent dinner. Fifty subjects (11 male, BMI: 21±2 kg/m2, age: 24±2 y) participated in a cross-over study in which they consumed ad libitum from a lunch with soft foods or hard foods on two separate days. Oral processing characteristics at lunch were assessed by coding video records. Later on the same days, subjects consumed dinner ad libitum. Hard foods led to a ∼13% lower energy intake at lunch compared to soft foods (Pfoods were consumed with smaller bites, longer oral duration per gram food, and more chewing per gram food compared to the soft foods (Pfoods led to reduced energy intake compared to soft foods, and this reduction in energy intake was sustained over the next meal. We argue that the differences in oral processing characteristics produced by the hardness of the foods explain the effect on intake. The sustained reduction in energy intake suggests that changes in food texture can be a helpful tool in reducing the overall daily energy intake.

To date, there have been no studies that have explicitly examined the effect of awareness on the consumption of food from a Universal Eating Monitor (UEM - hidden balance interfaced to a computer which covertly records eating behaviour). We tested whether awareness of a UEM affected consumption of a pasta lunch and a cookie snack. 39 female participants were randomly assigned to either an aware or unaware condition. After being informed of the presence of the UEM (aware) or not being told about its presence (unaware), participants consumed ad-libitum a pasta lunch from the UEM followed by a cookie snack. Awareness of the UEM did not significantly affect the amount of pasta or cookies eaten. However, awareness significantly reduced the rate of cookie consumption. These results suggest that awareness of being monitored by the UEM has no effect on the consumption of a pasta meal, but does influence the consumption of a cookie snack in the absence of hunger. Hence, energy dense snack foods consumed after a meal may be more susceptible to awareness of monitoring than staple food items. Copyright © 2015 The Authors. Published by Elsevier Ltd..

To analyse the Na content and labelling of processed and ultra-processed food products marketed in Brazil. Cross-sectional study. A large supermarket in Florianopolis, southern Brazil. Ingredient lists and Na information on nutrition labels of all processed and ultra-processed pre-prepared meals and prepared ingredients, used in lunch or dinner, available for sale in the supermarket. The study analysed 1416 products, distributed into seven groups and forty-one subgroups. Five products did not have Na information. Most products (58.8 %; 95 % CI 55.4, 62.2 %) had high Na content (>600 mg/100 g). In 78.0 % of the subgroups, variation in Na content was at least twofold between similar products with high and low Na levels, reaching 634-fold difference in the 'garnishes and others' subgroup. More than half of the products (52.0 %; 95 % CI 48.2, 55.6 %) had at least one Na-containing food additive. There was no relationship between the appearance of salt on the ingredients list (first to third position on the list) and a product's Na content (high, medium or low; P=0.08). Most food products had high Na content, with great variation between similar products, which presents new evidence for reformulation opportunities. There were inconsistencies in Na labelling, such as lack of nutritional information and incomplete ingredient descriptions. The position of salt on the ingredients list did not facilitate the identification of high-Na foods. We therefore recommend a reduction in Na in these products and a review of Brazilian legislation.

Sweet drinks early in life could predispose to lifelong consumption, and the beverage industry does not clearly define fruit drinks as part of the sweet drink category. To ascertain the relationship between beverage selection and dietary quality of the lunches packed for preschool-aged children evaluated using the Healthy Eating Index-2010. Foods packed by parents (n=607) were observed at 30 early care and education centers on two nonconsecutive days. Three-level regression models were used to examine the dietary quality of lunches by beverage selection and the dietary quality of the lunch controlling for the nutrient composition of the beverage by removing it from the analysis. Fruit drinks were included in 25% of parent-packed lunches, followed by 100% fruit juice (14%), milk (14%), and flavored milk (3.7%). Lunches with plain milk had the highest Healthy Eating Index-2010 scores (59.3) followed by lunches with 100% fruit juice (56.9) and flavored milk (53.2). Lunches with fruit drinks had the lowest Healthy Eating Index-2010 scores at 48.6. After excluding the nutrient content of the beverage, the significant difference between lunches containing milk and flavored milk persisted (+5.5), whereas the difference between fruit drinks and 100% fruit juice did not. Dietary quality is associated with the type of beverage packed and these differences hold when the lunch is analyzed without the nutrient content of the beverage included.

Background Eating habits are developed during the preschool years and track into adulthood, but few studies have quantified dietary quality of meals packed by parents for preschool children enrolled in early care and education centers. Objective Our aim was to evaluate the dietary quality of preschoolers’ sack lunches using the Healthy Eating Index (HEI) 2010 to provide parents of preschool children with guidance to increase the healthfulness of their child’s lunch. Design This study is a cross-sectional analysis of baseline dietary data from the Lunch Is in the Bag trial. Participants A total of 607 parent–child dyads from 30 early care and education centers in Central and South Texas were included. Main outcome measures Total and component scores of the HEI were computed using data obtained from direct observations of packed lunches and of children’s consumption. Statistical analysis Three-level regression models with random intercepts at the early care and education center and child level were used; all models were adjusted for child sex, age, and body mass index (calculated as kg/m2). Results Mean HEI-2010 total scores were 58 for lunches packed and 52 for lunches consumed, out of 100 possible points. Mean HEI component scores for packed and consumed lunches were lowest for greens and beans (6% and 8% of possible points), total vegetables (33% and 28%), seafood and plant proteins (33% and 29%), and whole grains (38% and 34%); and highest for empty calories (85% and 68% of possible points), total fruit (80% and 70%), whole fruit (79% and 64%), and total protein foods (76% and 69%). Conclusions Parents of preschool children pack lunches with low dietary quality that lack vegetables, plant proteins, and whole grains, as measured by the HEI. Education of parents and care providers in early care and education centers is vital to ensure that preschoolers receive high dietary-quality meals that promote their preference for and knowledge of a healthy diet.

This study aimed to investigate the nutritional quality and patterns of lunch menus provided by child care centers in South Korea and Japan. The weekly lunch menus from Monday to Saturday that child care centers provided in November 2014 in South Korea and Japan were analyzed. For Korea, a total of 72 meals provided by 12 centers in Seoul were analyzed by referring to the homepage of the Center for Children's Foodservice Management, which serviced menus for child care centers. For Japan, a total of 30 meals provided by 5 child care centers in Tokyo were analyzed. Nutrient content and pattern in lunch menus were evaluated. The lunch menus in Korea and Japan provided 359.5 kcal (25.7% of the estimated energy requirement) and 376.3 kcal (29.5% of the estimated energy requirement), respectively. 'Rice + Soup + Main dish + Side dish I + Side dish II' were provided in 66.7% of meals in Korea, while various patterns with rice and soup as their bases were provided in Japan. The lunch menus of child care centers in Korea and Japan provide similar amounts of energy, protein, carbohydrate, vitamin A, calcium, and other nutrients. However, there were significant differences in the lunch menu patterns in Korea and Japan. This study provides information about the nutritional content and pattern of lunch menus at child care centers in Asian countries with rice as a staple food.

Full Text Available Abstract Background Rye products have been demonstrated to lower the acute insulin demand, induce a low and prolonged blood glucose response (high Glycemic Profile, GP and reduce subclinical inflammation. These products may therefore contribute to a lowered risk of obesity, type 2 diabetes and cardio vascular disease. The objective of the present paper was to evaluate the mechanism for a reduced postprandial insulin demand with rye products, and to explore possible appetite regulating properties. Methods 10 healthy subjects were served breakfast meals (50 g of available starch with endosperm- or whole grain rye breads, with and without lactic acid, boiled whole grain rye- (RK or wheat (WK kernels, or white wheat bread reference (WWB in random order in a cross-over design. Plasma concentrations of glucose, ghrelin, serum insulin, free fatty acids, adiponectin, breath hydrogen excretion (H2, and subjective satiety was evaluated during the postprandial phase. 270 min after the breakfast, an ad lib lunch buffet was served and the voluntary energy intake (EI was registered. Results All rye products and WK induced lower insulinemic indices (II than WWB. A lower incremental insulin peak following breakfast correlated with a lower EI at lunch (r = 0.38. A low II was related to improved satiety in the early postprandial phase (fullness AUC 0-60 min, r = -0.36. RK induced a higher GP compared to WWB and WK. A higher GP was related to a lowered desire to eat before lunch (AUC 210-270 and to a lower concentration of ghrelin in the late postprandial phase after breakfast (270 min, r = -0.29 and -0.29, which in turn was related to a lower voluntary EI (r = 0.43 and 0.33. The RK breakfast improved satiety in the early postprandial phase (0-60 min compared to WWB, and induced a lower EI at lunch (-16%. A high content of indigestible carbohydrates in the breakfast products was related to improved satiety (0-60 min, r = 0.68 for fullness, and a higher breath H2

The practices and needs of dietitian in school lunch program in Taiwan.

Nutrition-related problems among school-age children nowadays become potentially serious. In order to prevent obesity and other nutritionally related diseases in the young generation, a school lunch program has been proposed and conducted in Taiwan. It is to ensure that students' nutritional intake meets the daily requirement and to help students develop correct eating habits and maintain a healthy lifestyle. A professional dietitian who has a clear concept regarding food material utilization, cooking methods and nutritional values thus becomes important. However, the majority of schools in Taiwan are unable to offer the post of dietitian due to budgetary constraints and lack of organization. The responsibility of a dietitian is usually held by teachers, school nurses and other administrative staff. This problem has hindered the nutritional education in schools and made school lunches less beneficial to the children's nutritional needs. For the current status of dietitians in schools, a large gap is found between the currently supplied school lunches and the nutritionally standardized school lunches. It also exists in relation to education and hygiene. One of the solutions requires an infrastructure to support plans and policy, reasonable adequate budget, well human affairs establishment and coordination of all aspects. While the needed infrastructure is being proposed, an access to the professionalism of the currently employed dietitians can be strategically explored by constructing an education system. Through the system, schools without on-campus dietitians will be able to utilize their expertise with which the improvement of school lunches can be expectedly accomplished.

Previous research showed that decreasing the energy density (kJ/g) of foods by adding water to them can lead to reductions in energy intake. Few studies have examined how water consumed as a beverage affects food intake. This study examined the effects of water, both served with a food and incorporated into a food, on satiety. In a within-subjects design, 24 lean women consumed breakfast, lunch, and dinner in our laboratory 1 d/wk for 4 wk. Subjects received 1 of 3 isoenergetic (1128 kJ) preloads 17 min before lunch on 3 d and no preload on 1 d. The preloads consisted of 1) chicken rice casserole, 2) chicken rice casserole served with a glass of water (356 g), and 3) chicken rice soup. The soup contained the same ingredients (type and amount) as the casserole that was served with water. Decreasing the energy density of and increasing the volume of the preload by adding water to it significantly increased fullness and reduced hunger and subsequent energy intake at lunch. The equivalent amount of water served as a beverage with a food did not affect satiety. Energy intake at lunch was 1209 +/- 125 kJ after the soup compared with 1657 +/- 148 and 1639 +/- 148 kJ after the casserole with and without water, respectively. Subjects did not compensate at dinner for this reduction in lunch intake. Consuming foods with a high water content more effectively reduced subsequent energy intake than did drinking water with food.

This study aimed to assess the amount of plate waste and how plate waste was disposed by early adolescent girls using a mobile food record (mFR). Participants were girls nine to thirteen years residing in O'ahu, Hawai'i ( n = 93). Foods selected and leftover were estimated using a three day mFR. Each leftover food was then classified as thrown into the trash, fed to a pet, eaten later, or other (e.g., composted). Repeated measures analyses of variance (ANOVA) were conducted and Tukey's post-hoc test were used to adjust for multiple comparisons between times (breakfast, lunch, dinner, and snack) on leftover food and leftover food thrown into the trash. The percentage of food leftover and thrown into the trash was highest at lunch. The percentage of protein, grain, vegetables, fruit, and dairy leftover at lunch were unexpectedly low compared to previous studies. The median for percentage of food thrown into the trash at lunch was <5% for all food groups, and was consistently low across the day (<10%). Average energy intake was 436 kcal (±216) at lunch, and 80% of caregivers reported total household income as ≥$70,000. Studies in real-time using technology over full days may better quantify plate waste among adolescents.

After the reactor accident of Fukushima nuclear power plant in Japan on March 11, 2011, many food adopted widely in school food service such as rice, wheat, milk are known to have risk for radioactivity contamination. To protect all children from exposure, the authors quantitatively examined risk assessment coming from food and conclude that radioactivity due to cesium 137 in rice, wheat, and milk for school lunch should be less than 10 Bq/kg and, furthermore from 2013, as lower as possible and less than 5 Bq/kg.

2006-07-01

Full Text Available Abstract Background Previous research has documented a negative association between maternal report of child food neophobia and reported frequency of consumption of fruit, vegetables, and meat. This study aimed to establish whether neophobia is associated with lower intake of these food types in naturalistic mealtime situations. Methods One hundred and nine parents of 4–5 year olds completed questionnaires which included a six-item version of the Child Food Neophobia Scale (CFNS. The children took part in a series of 3 test lunch meals at weekly intervals at school at which they were presented with: chicken, cheese, bread, cheese crackers, chocolate biscuits, grapes and tomatoes or carrot sticks. Food items served to each child were weighed before and after the meal to assess total intake of items in four categories: Fruit and vegetables, Protein foods, Starchy foods and Snack foods. Pearson Product Moment Correlations and independent t tests were performed to examine associations between scores on the CFNS and consumption during lunches. Results Neophobia was associated with lower consumption of fruit and vegetables, protein foods and total calories, but there was no association with intake of starch or snack foods. Conclusion These results support previous research that has suggested that neophobia impacts differentially on consumption of different food types. Specifically it appears that children who score highly on the CFNS eat less fruit, vegetables and protein foods than their less neophobic peers. Attempts to increase intake of fruit, vegetables and protein might usefully incorporate strategies known to reduce the neophobic response.

During recent years importance of B complex vitamins, beta-carotene and vitamin C has been realised in terms of their antioxidative and anticarcinogenic properties. Fruits and vegetables are the rich sources of these vitamins. However, there are considerable cooking losses of vitamins, and information on vitamin contents of cooked foods is essential for assessing the adequacy of vitamin intakes. Secondly, there is a growing trend to consume ready-to-eat foods such as stuffed pancakes (samosa, patties), pastries, French fries; replacing traditional foods for lunch or dinner like roti, vegetable curry, bread, non-vegetarian items. Ready-to-eat foods are considered to give empty calories rather than a balanced diet. A study was undertaken to estimate ascorbic acid, folic acid, riboflavin, thiamine and beta-carotene of 263 cooked food samples and 260 meals representing dietary patterns of Asia, Africa, Europe, USA and Latin America by spectrophotometry and photoflurometry. A broad range of beta-carotene (84-2038 mcg%), riboflavin (0.01-0.48 mg%), thiamine (0.04-0.36 mg%), vitamin C (1-28 mg%) and folate (26-111 mcg%) was observed in individual foods. Bakery products and sweets were found to be poor sources and green leafy vegetables and fruits were good sources of these five vitamins. The differences between ready-to-eat foods and meals consumed during lunch or dinner were prominent for beta-carotene, ascorbic acid, riboflavin and folic acid (P < 0.05). The cooking losses were 34.6, 30, 52.2, 45.9 and 32.2% in case of ascorbic acid, thiamine, riboflavin, beta-carotene and folic acid respectively. Irrespective of whether it is ready-to-eat or a lunch/dinner food item, the contribution of vegetables in the preparations was found to make a marked impact on the vitamin profile. While results justify the concept of a food pyramid, emphasis needs to be given to types of fruits and vegetables rich in vitamins; preferably in their uncooked form, rather than considering their

Adults often consume more fat than is recommended. We examined factors that may improve liking of reduced fat and reduced saturated fat foods, including the addition of herbs and spices and habitual consumption of different high-fat and low-fat food items. We randomized adults to taste 3 different conditions: full fat (FF), reduced fat with no added spice (RF), and reduced fat plus spice (RFS). Subjects rated their liking of French toast, sausage and the overall meal, or chicken, vegetables, pasta, and the overall meal on a 9-point hedonic Likert scale. Overall liking of the RF breakfast and lunch meals were lower than the FF and RFS versions (breakfast: 6.50 RF compared with 6.84 FF, P = 0.0061; 6.50 RF compared with 6.82 RFS, P = 0.0030; lunch: 6.35 RF compared with 6.94 FF, P spices may be useful for improving the liking of lower fat foods and helping Americans maintain a diet consistent with the U.S. Dietary Guidelines. Americans consume more fat than is recommended in the Dietary Guidelines for Americans. This study shows that you can take foods like French toast, chicken, or a vegetable side and cut the fat and calories by up to 50% while restoring flavor with herbs and spices. People typically use butter, cheese, or fatty meat to enhance the flavor of their food. We found that even when we reduced the fat in our meals by using lower fat dairy and meat products but then added herbs and spices, we were able to deliver the flavor people desire for a fraction of the calories. © 2014 Institute of Food Technologists®

To critically examine child-oriented packaged food products sold in Canada for their sodium content, and to assess them light of intake recommendations, the current policy context and suggested targets. Baby/toddler foods (n 186) and child-oriented packaged foods (n 354) were coded for various attributes (including sodium). Summary statistics were created for sodium, then the children's food products were compared with the UK Food Standards Agency (FSA) 'targets' for sodium in packaged foods. Also assessed were the products' per-serving sodium levels were assessed in light of the US Institute of Medicine's dietary reference intakes and Canada's Food Guide. Calgary, Alberta, Canada. None. Twenty per cent of products could be classified as having high sodium levels. Certain sub-categories of food (i.e. toddler entrées, children's packaged lunches, soups and canned pastas) were problematic. Significantly, when scaled in according to Schedule M or viewed in light of the serving sizes on the Nutrition Facts table, the sodium level in various dry goods products generally fell within, and below, the Adequate Intake (AI)/Tolerable Upper Intake Level (UL) band for sodium. When scaled in accordance with the UK FSA targets, however, none of the (same) products met the targets. In light of AI/UL thresholds based on age and per-serving cut-offs, packaged foodstuffs for youngsters fare relatively well, with the exception of some problematic areas. 'Stealth sodium' and 'subtle sodium' are important considerations; so is use of the FSA's scaling method to evaluate sodium content, because it is highly sensitive to the difference between the reference amount and the actual real-world serving size for the product being considered.

Our objective was to investigate whether school lunch attendance was associated with overall eating habits and sedentary behaviour in a French sample of children and adolescents. Data for the study were taken from the second French cross-sectional dietary survey (INCA2-2006-07). In total, 1413 school children aged 3-17 years old were classified according to their school type and their usual school lunch attendance. Eating habits included meal regularity, dietary diversity, purchase in vending machine, snacking habits and frequency of eating in fast-foods. Two composite indices of eating habits were derived from multiple correspondence analyses. Sedentary behaviour was assessed by the average daily screen times for TV and computer. The association between school lunch attendance and each variable was tested. Multivariate association between school lunch attendance and the composite indices of eating habits and sedentary behaviours was studied. In all, 69.0% (CI(95%): 64.2-73.9) of secondary school children and 63.0% (CI(95%): 58.5-67.5) of pre- and elementary school children usually attended school lunch at least once a week. Pre- and elementary school children attending school lunches showed a higher dietary diversity score (P=0.02) and ate morning snacks more frequently (P=0.02). In secondary school children, attending school canteen was related to a lower rate of skipping breakfast (P=0.04) and main meals (P=0.01). In all school children, school lunch attendance was simultaneously associated with healthier overall eating habits and less sedentary behaviour. In France, children attending school canteens seem to have healthier eating habits and display less sedentary behaviour, independently of their socio-economic and demographic background.

A review of the effects of lunch on adults' short-term cognitive functioning.

Science.gov (United States)

Müller, Katrin; Libuda, Lars; Terschlüsen, Anna Maria; Kersting, Mathilde

2013-01-01

Because of widespread irregular lunch consumption by both children and adults, information on the effects of lunch on short-term cognitive functioning is relevant to public health. In September 2012, a MEDLINE search was conducted for studies in which the effects of lunch on cognitive performance were examined. Eleven experimental studies published from 1981 to 1996 were found and evaluated; all involved adults. In three studies, the effects of lunch and lunch skipping were compared; the remaining studies involved a determination of the effects of lunch size and lunch composition. Results of studies in which lunch was compared with no lunch indicate that lunch leads to potential impairment of some aspects of cognitive functioning in the early afternoon. Lunch size may influence cognitive functioning, with impairment more likely to occur after a large lunch than a small lunch. Furthermore, in comparison with low-fat lunches, high-fat lunches seem to result in slower but more accurate responses to some cognitive tasks. However, these suggestions must be viewed with caution, as they are based on only a few studies and are not thoroughly supported by high-quality evidence. In addition, results obtained with adults are not applicable to children. Thus, the potential effects of lunch need further examination in children and adults.

Misreporting food intake is common because most health screenings rely on self-reports. The more accurate methods (eg, weighing food) are costly, time consuming, and impractical. We developed a new instrument for reporting food intake--an Internet-based interactive virtual food plate. The objective of this study was to validate this instrument's ability to assess lunch intake. Participants were asked to compose an ordinary lunch meal using both a virtual and a real lunch plate (with real food on a real plate). The participants ate their real lunch meals on-site. Before and after pictures of the composed lunch meals were taken. Both meals included identical food items. Participants were randomized to start with either instrument. The 2 instruments were compared using correlation and concordance measures (total energy intake, nutritional components, quantity of food, and participant characteristics). A total of 55 men (median age: 45 years, median body mass index [BMI]: 25.8 kg/m(2)) participated. We found an overall overestimation of reported median energy intake using the computer plate (3044 kJ, interquartile range [IQR] 1202 kJ) compared with the real lunch plate (2734 kJ, IQR 1051 kJ, P<.001). Spearman rank correlations and concordance correlations for energy intake and nutritional components ranged between 0.58 to 0.79 and 0.65 to 0.81, respectively. Although it slightly overestimated, our computer plate provides promising results in assessing lunch intake.

To investigate: (i) how lunch frequency of adolescents varies between schools and between classes within schools; (ii) the associations between frequency of lunch and individual sociodemographic factors and school characteristics; and (iii) if any observed associations between lunch frequency and school characteristics vary by gender and age groups. Cross-sectional study in which students and school headmasters completed self-administered questionnaires. Associations were estimated by multilevel multivariate logistic regression. The Danish arm of the Health Behaviour in School-Aged Children study 2010. Students (n 4922) aged 11, 13 and 15 years attending a random sample of seventy-three schools. The school-level and class-level variations in low lunch frequency were small (intraclass correlation coefficient lunch frequency was most common among students who were boys, 13- and 15-year-olds, from medium and low family social class, descendants of immigrants, living in a single-parent family and in a reconstructed family. School-level analyses suggested that having access to a canteen at school was associated with low lunch frequency (OR=1·47; 95% CI 1·14, 1·89). Likewise not having an adult present during lunch breaks was associated with low lunch frequency (OR=1·44; 95% CI 1·18, 1·75). Cross-level interactions suggested that these associations differed by age group. Lunch frequency among Danish students appears to be largely influenced by sociodemographic factors. Additionally, the presence of an adult during lunch breaks promotes frequent lunch consumption while availability of a canteen may discourage frequent lunch consumption. These findings vary between older and younger students.

Full Text Available Abstract Background The association of obesity and dietary patterns has been well documented in scientific literature; however, information on the impact of meal patterns on obesity is scarce. The objective of this study was to investigate the association of adherence to lunch patterns and body mass index (BMI in a representative sample of individuals aged 20 years or older in Sao Paulo. Methods Data for 933 participants were retrieved from the Health Survey of São Paulo (ISA-Capital 2008, a cross-sectional population-based survey. The usual dietary intake of individuals with at least one 24-h recall was estimated by the Multiple Source Method. The definition of lunch was self-reported by the participant. Five lunch patterns were derived from twenty-two food groups by exploratory factor analysis: Traditional, Western, Sweetened juice, Salad, and Meats. To estimate the effect of lunch patterns on BMI, we used a generalized linear model with link identity and inverse Gaussian distribution. Analyses were adjusted by age, gender, household income per capita, physical activity levels, smoking status, alcohol consumption, total energy intake, and misreporting status. Results The greater adherence to the traditional pattern at the lunch meal was associated with lower BMI, only in insufficiently active individuals (ß = −0.78; 95% CI -1.57; −0.02. Conclusions The traditional Brazilian lunch pattern might protect the insufficiently active individuals against obesity.

School cafeterias can play an important role in providing healthy meals. Although schools participating in the National School Lunch Program are required to meet minimum program standards, advocates recommend that innovations be sought to enhance menu dietary quality. This study evaluated the Chef Initiative, a 2-year pilot study in two Boston middle schools, designed to increase the availability and consumption of healthier school foods. Between 2007 and 2009, a professional chef trained cafeteria staff to prepare healthier school lunches (ie, more whole grains, fresh/frozen fruits and vegetables, and less sugar, salt, saturated fats, and trans fats). Meal nutrient compositions were monitored from 2007 to 2009, and a plate waste study conducted in the spring of 2009 compared food selection and consumption patterns among students at Chef Initiative schools, with students receiving standard school lunches at two matched control schools. Paired t tests and descriptive statistics were used to examine differences in menus and mixed-model analysis of variance was used to analyze differences in students' food selection and consumption between Chef Initiative and control schools. Overall, the Chef Initiative schools provided healthier lunches and the percent of foods consumed at Chef Initiative and control schools were similar (61.6% vs 57.3%; P=0.63). Of the areas targeted, there was greater whole-grain selection and vegetable consumption; 51% more students selected whole grains (P=0.02) and students consumed 0.36 more vegetable servings/day (P=0.01) at Chef Initiative schools. The potential of chefs collaborating with cafeteria staff to improve the availability, selection, and consumption of healthier meals is promising. Copyright © 2012 Academy of Nutrition and Dietetics.

2017-01-01

Food labelling has been previously reported to influence energy intake (EI). Whether food labels influence postexercise EI remains to be determined. We assessed how food labelling and exercise (Ex) interact to influence food perception and postexercise EI. In this randomized crossover design, 14 inactive women participated in 4 experimental conditions: Ex (300 kcal at 70% of VO 2peak ) and lunch labelled as low in fat (LF), Ex and lunch labelled as high in fat (HF), Rest and LF, and Rest and HF. The lunch was composed of a plate of pasta, yogurt, and oatmeal cookies, which had the same nutritional composition across the 4 experimental conditions. EI at lunch and for the 48-hour period covering the testing day and the following day was assessed. Furthermore, perceived healthiness of the meal and appetite ratings were evaluated. There were no effects of exercise and food labelling on EI. However, meals labelled as LF were perceived as heathier, and this label was associated with higher prospective food consumption. Initial beliefs about food items had a stronger effect on healthiness perception than the different food labels and explain the positive correlation with the amount of food consumed ( ρ = 0.34, P < 0.001).

Childhood obesity is a major public health concern and is associated with substantial morbidities. Access to less-healthy foods might facilitate dietary behaviors that contribute to obesity. However, less-healthy foods are usually available in school vending machines. This cross-sectional study examined the prevalence of students buying snacks or beverages from school vending machines instead of buying school lunch and predictors of this behavior. Analyses were based on the 2003 Florida Youth Physical Activity and Nutrition Survey using a representative sample of 4,322 students in grades six through eight in 73 Florida public middle schools. Analyses included χ2 tests and logistic regression. The outcome measure was buying a snack or beverage from vending machines 2 or more days during the previous 5 days instead of buying lunch. The survey response rate was 72%. Eighteen percent of respondents reported purchasing a snack or beverage from a vending machine 2 or more days during the previous 5 school days instead of buying school lunch. Although healthier options were available, the most commonly purchased vending machine items were chips, pretzels/crackers, candy bars, soda, and sport drinks. More students chose snacks or beverages instead of lunch in schools where beverage vending machines were also available than did students in schools where beverage vending machines were unavailable: 19% and 7%, respectively (P≤0.05). The strongest risk factor for buying snacks or beverages from vending machines instead of buying school lunch was availability of beverage vending machines in schools (adjusted odds ratio=3.5; 95% confidence interval, 2.2 to 5.7). Other statistically significant risk factors were smoking, non-Hispanic black race/ethnicity, Hispanic ethnicity, and older age. Although healthier choices were available, the most common choices were the less-healthy foods. Schools should consider developing policies to reduce the availability of less-healthy choices

The transient nature of construction work makes it difficult to conduct longitudinal worksite-based health promotion activities. As part of a workplace health assessment pilot study, we worked with a commercial lunch truck company to disseminate four types of health education materials including cancer screening, workplace injury prevention, fruit and vegetable consumption, and smoking cessation to construction workers purchasing food items from the truck during their job breaks. Two weeks following the worksite assessment, we followed up with these workers to ascertain their use of the health promotion materials. Of the 54 workers surveyed, 83% reported reviewing and sharing the cancer screening materials with their families, whereas 44% discussed the cancer screening materials with coworkers. Similar proportions of workers reviewed, shared, and discussed the other health promotion materials with their family. Lunch trucks may be an effective strategy and delivery method for educating construction workers on healthy behaviors and injury prevention practices.

Lunch, recess and nutrition: responding to time incentives in the cafeteria.

Price, Joseph; Just, David R

2015-02-01

In this study, we evaluate if moving recess before lunch has an effect on the amount of fruits and vegetables elementary school students eat as part of their school-provided lunch. Participants were 1st-6th grade students from three schools that switched recess from after to before lunch and four similar schools that continued to hold recess after lunch. We collected data for an average of 14 days at each school (4 days during spring 2011, May 3 through June 1, 2011 and 9 days during fall 2011, September 19 through November 11, 2011). All of the schools were in Orem, UT. Data was collected for all students receiving a school lunch and was based on observational plate waste data. We find that moving recess before lunch increased consumption of fruits and vegetables by 0.16 servings per child (a 54% increase) and increased the fraction of children eating at least one serving of fruits or vegetables by 10 percentage points (a 45% increase). In contrast, the schools in our control group actually experienced a small reduction in fruit and vegetable consumption during the same time period. Our results show the benefits of holding recess before lunch and suggest that if more schools implement this policy, there would be significant increases in fruit and vegetable consumption among students who eat school lunch as part of the National School Lunch Program.

2017-02-01

It is unclear whether Supplemental Nutrition Assistance Program (SNAP) or National School Lunch Program (NSLP) participation modifies the relationship between food insecurity and obesity in children. Data were included for 4,719 children aged 9-17 years who participated in the National Health and Nutrition Survey between 2003-2004 and 2011-2012. Linear regression was used to examine the relationship between household food security (full, marginal, low, and very low) and BMI percentile. Adjusted models were also stratified by SNAP and NSLP participation. There was no significant overall relationship between household food security and BMI percentile. In SNAP non-participants, there was no apparent overall relationship between BMI percentile and household food security. However, BMI percentile in children from households with low food security was significantly higher than that of children from fully food-secure households (risk difference [RD]=5.95, 95% CI=1.11, 10.80). Among SNAP participants, there was no significant relationship between household food security and BMI percentile. By NSLP participation category, there was a non-significant trend toward increasing BMI percentile with decreasing household food security in those reporting two or fewer (RD=1.75, 95% CI= -0.79, 4.29) and two to three (RD=1.07; 95% CI= -1.74, 3.89) lunches/week. There was no apparent relationship between household food security and BMI percentile in those reporting four or more lunches/week. Although the overall relationship between household food security and weight status in school-aged children was not statistically significant, there was some evidence that the relationship may differ by SNAP or NSLP participation, suggesting the need for more research.

2013-06-01

Nutrition labelling is an important strategic approach for encouraging consumers to make healthier food choices. The availability of highly palatable foods labelled as 'low fat or reduced calorie' may encourage the over-consumption of these products. This study aimed to determine whether the manipulation of nutrition labelling information can influence food portion size consumption. Normal and overweight men (n=24) and women (n=23) were served an identical lunch meal on three separate days, but the information they received prior to consuming the lunch meal was manipulated as follows: "baseline", "high fat/energy" and "low fat/energy". Food and energy intake was significantly increased in the low fat/energy condition compared with both baseline and the high fat/energy condition. An additional 3% (162 kJ) energy was consumed by subjects under the low fat/energy condition compared to baseline. No differences were observed between the baseline and high fat/energy condition. Subjects who consumed most in the low fat/energy condition were found to be mostly men, to have a higher BMI and to be overweight. Low fat/energy information can positively influence food and energy intake, suggesting that foods labelled as 'low fat' or 'low calorie' may be one factor promoting the consumption of large food portions.

School canteens have an important role in modelling a healthy food environment. Price is a strong predictor of food and beverage choice. This study compared the relative price of healthy and less healthy lunch and snack items sold within Australian school canteens. A convenience sample of online canteen menus from five Australian states were selected (100 primary and 100 secondary schools). State-specific canteen guidelines were used to classify menu items into 'green' (eat most), 'amber' (select carefully) and 'red' (not recommended in schools). The price of the cheapest 'healthy' lunch (vegetable-based 'green') and snack ('green' fruit) item was compared to the cheapest 'less healthy' ('amber/red') lunch and snack item, respectively, using an un-paired t-test. The relative price of the 'healthy' items and the 'less healthy' items was calculated to determine the proportion of schools that sold the 'less healthy' item cheaper. The mean cost of the 'healthy' lunch items was greater than the 'less healthy' lunch items for both primary (AUD $0.70 greater) and secondary schools ($0.50 greater; p snack was cheaper than the 'healthy' snack. These proportions were greatest for primary schools located in more, compared to less, disadvantaged areas. The relative price of foods sold within Australian school canteens appears to favour less healthy foods. School canteen healthy food policies should consider the price of foods sold.

Food poisoning due to Salmonella Enteritidis--a case report.

2009-04-01

A male in his early seventies complained of abdominal pain and diarrhea at 7h after ingesting a small piece of gratin from a box lunch prepared by a caterer. He was admitted to a hospital, but died 37 h later. Dozens of people who had eaten the same box lunch also complained of diarrhea. All of them recovered after medical treatment. A later investigation demonstrated Salmonella Enteritidis (SE) in the gratin from the box lunch. An autopsy revealed very severe typhloenteritis with edema and submucosal hemorrhage. The digestive tract contained fluid contents without foodstuffs. Bacteriological examination revealed SE in the contents of the lower ileum and large intestine. Based on these findings, we concluded that the cause of death was food poisoning due to SE. In this case, ingesting only a small piece of contaminated food caused fatal food poisoning due to SE. These results emphasize the importance of prevention against food poisoning due to Salmonella, particularly SE.

To investigate the feasibility of Fabuless (previously called Olibra and Reducal) as a food ingredient for food intake and appetite reduction, by assessing the effects of food processing on efficacy. In total, 24 healthy volunteers (16 female, 8 male; age: 18-43 years; body mass index: 18-37 kg/m(2)) took part in a randomized, placebo-controlled, double-blinded, cross-over trial. Yoghurt-based meal replacement drinks (containing processed or unprocessed Fabuless, or a control fat) were followed by an ad libitum lunch and evening meal (dinner). Key outcome measures were energy intake and self-reported appetite ratings. Compared with control, only unprocessed Fabuless reduced subsequent energy intake, although only during dinner (P processed and unprocessed: 4.3, 3.9 and 4.2 MJ, respectively) and not during lunch (3.6, 3.7 and 3.6 MJ). Self-reported appetite scores did not differ between treatments. Although modest effects of unprocessed Fabuless were seen on food intake, but not on appetite, the ingredient was not robust to common food-manufacturing processes (thermal and shear processing). Claims on reduced food intake and appetite relating to this ingredient in food products are, therefore, only valid if functionality has been demonstrated after all relevant processing and storage steps.

The aim of this study was to investigate whether food reward plays a role in the stimulating effect of moderate alcohol consumption on subsequent food intake. In addition, we explored the role of oral and gut sensory pathways in alcohol's effect on food reward by modified sham feeding (MSF) or consumption of a preload after alcohol intake.In a single-blind crossover design, 24 healthy men were randomly assigned to either consumption of vodka/orange juice (20 g alcohol) or orange juice only, followed by consumption of cake, MSF of cake or no cake. Food reward was evaluated by actual food intake measured by an ad libitum lunch 45 min after alcohol ingestion and by behavioural indices of wanting and liking of four food categories (high fat, low fat, sweet and savoury).Moderate alcohol consumption increased food intake during the ad libitum lunch by 11% (+338 kJ, P = 0.004). Alcohol specifically increased intake (+127 kJ, P foods. Moreover, moderate alcohol consumption increased implicit wanting for savoury (P = 0.013) and decreased implicit wanting for sweet (P = 0.017) before the meal. Explicit wanting of low-fat savoury foods only was higher after alcohol followed by no cake as compared to after alcohol followed by cake MSF (P = 0.009), but not as compared to alcohol followed by cake consumption (P = 0.082). Both cake MSF and cake consumption had no overall effect on behavioural indices of food reward.To conclude, moderate alcohol consumption increased subsequent food intake, specifically of high-fat savoury foods. This effect was related to the higher food reward experienced for savoury foods. The importance of oral and gut sensory signalling in alcohol's effect on food reward remains largely unclear.

Novel ways to increase liking and intake of food are needed to encourage acceptance of healthier food. How enjoyable we remember food to have been is likely to be a significant predictor of food choice. Two studies examined whether remembered enjoyment of eating a food can be increased and whether this makes individuals more likely to eat that food in the future. In Study One, a simple manipulation of instructing participants to rehearse what they found enjoyable about a food immediately after eating it was used to increase remembered enjoyment (relative to controls). In a separate study; Study Two, the effect of increasing remembered enjoyment on food choice was tested by examining whether the manipulation to increase remembered enjoyment resulted in participants choosing to eat more of a food as part of a later buffet lunch. The experimental manipulation increased remembered enjoyment for the food (Study One). A change in remembered enjoyment was shown to have a significant effect on the amount of a food participants chose to eat the following day for lunch (Study Two). The present studies suggest that remembered enjoyment can be increased via a simple act of rehearsal, resulting in a later increase in the amount of food chosen and eaten. Interventions based on altering remembered enjoyment of healthy food choices warrant further investigation.

ATLAS Christmas lunch

CERN Document Server

Francois Butin; Markus Nordberg

The end of the year ATLAS pit lunch is now a well established tradition: the 4th edition took place in the most prestigious place at CERN; the "Globe de l'innovation", or simply "the Globe". This end-of-year event is the opportunity to thank all those working so hard at Point 1. The first event took place in December 2003. At that time, there was no Globe yet, and the party took place in SX1 building, at the top of the shafts leading to the ATLAS cavern, with some 100 guests. In December 2004, we had the privilege to be the first to organize a lunch in the Globe with some 200 guests. Since then, many have followed our example! Well, almost: we were requested to refrain from serving "Tartiflette" again in there (a Savoyard specialty, using vast amounts of Reblochon, a smelly cheese...). It was said to have left a poignant odour for following events throughout 2004... Long queues formed for this special event. In December 2005, we were authorized to party in the Globe again (once we promised we would b...

Recent reports have suggested that a low glycemic index (GI) diet may have a role in the management of obesity through its ability to increase the satiety value of food and modulate appetite. To date, no long-term clinical trials have examined the effect of dietary GI on body weight regulation. The majority of evidence comes from single-day studies, most of which have been conducted in adults. The purpose of this study was to investigate the effect of 3 test breakfasts-low-GI, low-GI with 10% added sucrose, and high-GI-on ad libitum lunch intake, appetite, and satiety and to compare these with baseline values when habitual breakfast was consumed. A 3-way crossover study using block randomization of breakfast type was conducted in a school that already ran a breakfast club. A total of 37 children aged 9 to 12 years (15 boys and 22 girls) completed the study. The proportion of nonoverweight to overweight/obese children was 70:30. Children were divided into 5 groups, and a rolling program was devised whereby, week by week, each group would randomly receive 1 of 3 test breakfasts for 3 consecutive days, with a minimum of 5 weeks between the test breakfasts. Participants acted as their own control. The 3 test breakfasts were devised to match the energy and nutritional content of an individual's habitual breakfast as far as possible. All test breakfasts were composed of fruit juice, cereal, and milk with/without bread and margarine; foods with an appropriate GI value were selected. After each test breakfast, children were instructed not to eat or drink anything until lunchtime, except water and a small serving of fruit supplying approximately 10 g of carbohydrate, which was provided. Breakfast palatability, satiation after breakfast, and satiety before lunch were measured using rating scales based on previously used tools. Lunch was a buffet-style meal, and children were allowed free access to a range of foods. Lunch was served in the school hall where the rest of the

To examine changes in the Na content of lunch/dinner menu offerings at eight of the leading fast-food restaurants in the USA between 1997/1998 and 2009/2010. Menu offerings and nutrient composition information for the menu items were obtained from archival versions of the University of Minnesota Nutrition Coordinating Center (NCC) Food and Nutrient Database. Nutrient composition information for lunch/dinner menu items sold by the fast-food restaurants included in the present study was updated in the database biannually. Menus were analysed for changes in mean Na content of all menu offerings (except beverages) and specific categories of menu items among all restaurants and for each individual restaurant. Lunch/dinner food menu of eight leading US fast-food restaurants. Between 1997/1998 and 2009/2010 the mean Na content of menu offerings across the eight restaurants increased by 23·4 %. Examining specific food categories, mean Na content of entrées by increased 17·2 % and that of condiments increased by 26·1 %. Only side dishes showed a decrease of 6·6 %. None of the restaurants examined had a decrease in Na across the lunch/dinner menu offerings over the 14 years examined. Results suggest that over the time period studied there has been no meaningful reduction in the Na content of lunch/dinner menu offerings at the leading fast-food restaurants examined in the present study.

Food and nutrition security are intimately interconnected, since only a food based approach can help in overcoming malnutrition in an economically and socially sustainable manner. Food production provides the base for food security as it is a key determinant of food availability. This paper deals with different aspects of ensuring high productivity and production without associated ecological harm for ensuring adequate food availability. By mainstreaming ecological considerations in technology development and dissemination, we can enter an era of evergreen revolution and sustainable food and nutrition security. Public policy support is crucial for enabling this.

The aim of the present study was to investigate the possible associations between dietary energy density (ED) and the metabolic syndrome (MetS) in patients with type 2 diabetes. In the present case-control study, the dietary ED of 125 patients with type 2 diabetes (seventy-eight with (cases) the MetS and forty-seven without (controls) the MetS; mean age 62·0 (SD 9·4) years, mean diabetes duration 12·5 (SD 8·4) years and mean glycated Hb 7·2 (SD 1·3) %) was assessed by weighed diet records. The MetS was defined according to the 2009 Joint Interim Statement and ED by the amount of energy (kJ) in a given weight of food. Data are expressed as means (standard deviations) or medians (interquartile ranges). Patients with the MetS reported lower intakes of total energy and fibre, and a higher total food amount than the controls; the total ED did not differ, but the cases had a higher ED at lunch (mean 6·3 (SD 1·3) v. 5·9 (SD 0·8) kJ/g; P= 0·017). In this meal, patients with the MetS had lower intakes of beans (median 0·7 (interquartile range 0·4-1·1) v. 1·1 (interquartile range 0·6-1·6) g/kg; P= 0·020), vegetables (median 1·2 (interquartile range 0·6-1·7) v. 1·4 (interquartile range 1·0-2·0) g/kg; P= 0·046) and total meat (median 1·3 (interquartile range 1·0-1·6) v. 1·4 (interquartile range 1·2-1·8) g/kg; P= 0·034) than patients without the MetS. The associations between lunch ED (kJ/g) and food groups (g/kg) were confirmed for vegetables (r - 0·584; P< 0·001), fruits (r - 0·233; P= 0·070), beans (r - 0·189; P= 0·037) and oils (r 0·323; P< 0·001). In a multivariate logistic regression model, a high lunch ED was associated with the MetS (OR 6·89, 95 % CI 1·35, 35·15; P =0·020) after adjusting for confounders. In conclusion, a high ED at lunch increased the odds of the presence of the MetS in patients with type 2 diabetes. Beans and vegetables may be the major contributors to this association and their consumption might be

Full Text Available Abstract Background In February 2015 an outbreak of gastroenteritis occurred in a distillery in Kinmen, Taiwan. At least 450 affected employees developed the symptoms of diarrhea and vomiting after attending a lunch banquet on 6 February. Epidemiological, laboratory and environmental investigations were conducted to identify the agent and source of this outbreak. Methods A case–control study was carried out among lunch attendees from the distillery. Using a semi-structured questionnaire, food and beverage consumption in the lunch banquet was assessed, as well as demographic and clinical data of the exposed people. An outbreak case was defined as a diner who developed at least three following symptoms: diarrhea, vomiting, abdominal pain, nausea, chills and/or weakness in the 72 h following the lunch. Controls were defined as lunch attendees who did not have any of the above symptoms. Rectal swabs or stool samples of the symptomatic exposed diners and food handlers as well as food and environmental samples were collected to test potential bacteria and viruses. Norovirus was detected by reverse transcription-polymerase chain reaction and sequence analysis. An environmental assessment, including environmental inspection of the restaurant and a review of work practices of food workers, was undertaken. Results Of 363 respondents with complete data, 169 met the case definition and 111 met the control definition. Consumption of pork liver in cold appetizers (adjusted odd ratio (aOR 3.23; 95 % confidence interval (CI: 1.26–8.30 and lamb chops (aOR: 3.98, 95 % CI: 1.74–9.11 were each associated with increased risk of illness. No cases but two asymptomatic food handlers who prepared or cooked the implicated foods tested positive for norovirus genotype I.6. Food and environmental samples were negative for any bacteria. Environmental assessment indicated that hand washing facilities were not properly accessible to food handlers. Inappropriate

The School Lunch Program in India (SLP) is the largest food and nutrition assistance program feeding millions of children every day. This paper provides a review of the background information on the SLP in India earlier known as national program for nutrition support to primary education (NP-NSPE) and later as mid day meal scheme, including historical trends and objectives and components/characteristics of the scheme. It also addresses steps being taken to meet challenges being faced by the administrators of the program in monitoring and evaluation of the program. This program was initially started in 1960 in few states to overcome the complex problems malnutrition and illiteracy. Mid Day Meal Scheme is the popular name for school meal program. In 2001, as per the supreme court orders, it became mandatory to give a mid day meal to all primary and later extended to upper primary school children studying in the government and government aided schools. This scheme benefitted 140 million children in government assisted schools across India in 2008, strengthening child nutrition and literacy. In a country with a large percent of illiterate population with a high percent of children unable to read or write; governmental and non-governmental organizations have reported that mid day meal scheme has consistently increased enrollment in schools in India. One of the main goals of school lunch program is to promote the health and well-being of the Nation's children.

Better techniques are needed to help consumers make lower calorie food choices. This pilot study examined the effect of menu labeling with caloric information and exercise equivalents (EE) on food selection. Participants, 62 females, ages 18-34, recruited for this study, ordered a fast food meal with menus that contained the names of the food (Lunch 1 (L1), control meal). One week later (Lunch 2 (L2), experiment meal), participants ordered a meal from one of three menus with the same items as the previous week: no calorie information, calorie information only, or calorie information and EE. There were no absolute differences between groups in calories ordered from L1 to L2. However, it is noteworthy that calorie only and calorie plus exercise equivalents ordered about 16% (206 kcal) and 14% (162 kcal) fewer calories from Lunch 1 to Lunch 2, respectively; whereas, the no information group ordered only 2% (25 kcal) fewer. Menu labeling alone may be insufficient to reduce calories; however, further research is needed in finding the most effective ways of presenting the menu labels for general public.

Contaminated fresh produce has been increasingly identified as a cause of foodborne illnesses. Because of concerns about pathogen growth on these food items at retail, the 2009 U.S. Food and Drug Administration Food Code established that cut leafy greens (lettuce, spinach, spring mix, cabbage, arugula, and kale) must have time and temperature controls for safety and hence should be kept at refrigerated temperatures (5°C or lower). The purpose of this study was to determine the temperature profiles of cut leafy greens in single-serving clamshell containers provided as part of the North Carolina School Lunch Program and to compare the two policies that North Carolina has in place to control the temperature of these products (the 3-day rule and time in lieu of temperature). Temperatures were recorded with data loggers in 24 schools during a 3-day period. In all cases, substantial temperature variability was found for these products, including temperatures above 5°C for at least 1 h on each of the 3 days. In some cases, temperatures reached above 5°C for more than 3 h throughout the serving time. The results demonstrate the importance of developing a protocol for continuous temperature monitoring of leafy greens served in school lunch programs.

Dietary intake among children in the United States falls short of national recommendations. Schools can play an important role in improving children's preferences and food consumption patterns. The US Department of Agriculture's Fresh Fruit and Vegetable Program (FFVP) aims to improve children's nutrient intake patterns by offering fresh fruits and vegetables as snacks outside the reimbursable meals programs in elementary schools that serve large numbers of low-income children. Using a nationally representative sample of public elementary schools, this cross-sectional study investigated FFVP participation patterns among schools by demographic and school characteristics. Further, the study investigated the association between FFVP participation and availability of fresh fruits, salads, and vegetables at lunch as reported by school administrators and foodservice staff. Data collected via a mail-back survey from 620 public elementary schools participating in the National School Lunch Program during 2009-2010 were analyzed. Almost 70% of the FFVP-participating schools had a majority of students (>50%) eligible for free and reduced-cost meals. Participating in US Department of Agriculture Team Nutrition Program and having a registered dietitian or a nutritionist on staff were significantly associated with FFVP participation. Based on the results from logistic regression analyses schools participating in the FFVP were significantly more likely (odds ratio 2.07; 95% CI 1.12 to 3.53) to serve fresh fruit during lunch meals. Slightly >25% of public elementary schools across the United States participated in the FFVP, and participation was associated with healthier food availability in school lunches.

This study aimed to examine the association between meal-specific food patterns and incident hyperglycaemia in a Chinese adult population. Adults aged 20 years and older (n 1056) were followed from 2002 to 2007. Dietary data were collected using a 3-d food record and meal-specific (breakfast, lunch and dinner) food patterns were independently described by factor analysis based on the consumption of thirty-five food groups at each eating occasion. Each food pattern score was recoded as quartiles. Hyperglycaemia was defined as fasting plasma glucose >5·6 mmol/l at baseline and follow-up. The associated between food patterns and incident hyperglycaemia was assessed by logistic regression. During the follow-up, 125 new cases of hyperglycaemia were identified. Traditional (wheat) breakfast was inversely associated with incident hyperglycaemia, whereas traditional (rice, vegetable and pork) lunch and dinner were positively associated with the risk of incident hyperglycaemia, even after adjustment for a number of covariates including glycaemic load, carbohydrate intake and BMI. Incident hyperglycaemia occurred in 15·9, 13·6, 11·7, 6·1 % across quartiles of traditional breakfast; and 5·3, 9·1, 15·9, 17·1 % of the quartiles of traditional lunch pattern. The adjusted OR for hyperglycaemia was 0·67 (95 % CI 0·48, 0·92), 1·83 (95 % CI 1·32, 2·53) and 1·39 (95 % CI 1·04, 1·86) for 1 sd increase of traditional breakfast, lunch and dinner pattern factor score, respectively. A traditional wheat-based breakfast is associated with a decreased risk of hyperglycaemia. A rice-based traditional lunch and dinner is associated with an increased risk of hyperglycaemia in Chinese adults.

Studies were carried out to assess consumer attitude towards food irradiation through questionnaires, sensory tests and market sale of irradiated products. The results showed that out of 1020 persons responded to the questionnaire, 62.43% accepted the irradiation technology while 70.45% were convinced with the advantages of irradiated food. About 73.97% of the respondents were willing to accept irradiation technology on a long term basis while 57.53% were willing to consume irradiated food if it was available in the market. Sensory tests on irradiated smoked fish, chicken, black pepper, coriander, Jew's mallow, broad bean and kidney beans using triangle test (difference test) and duo-trio test showed that the panelists consisting of 136 persons failed to indicate any difference between the irradiated and unirradiated food. About 92.2% of 144 persons participating in a lunch table of irradiated food opined that irradiated food was delicious and found no difference between the irradiated and unirradiated samples. Consumer comments recorded during the market sale of irradiated black pepper and broad beans indicated that 95.1% of the respondents found the irradiated (10kGy) black pepper of excellent or good quality while the percentage was 81.2% for irradiated (2 kGy) broad bean. The study also showed that 62.2% and 68.8% of the persons respectively would buy irradiated black pepper and broad bean again if they were available in the market. Studies on the economics of food irradiation showed that the cost of irradiation for one ton of frozen poultry as US $130.4; smoked fish US $78.2; spices US $260.1 and dried vegetable US $26. Economic evaluation of the study indicated that the average annual rate of return will be about 16.9% and the pay back period will be about 5.9 years. (author)

The study of meal patterns and overall diet in relation to health outcomes may be more important than focusing on single nutrients or food groups. The present study aimed to explore the composition of main meals and snacks in the Australian population and examine associations between meat/poultry/fish and other foods. The study utilised 24 h recalls. Meal composition was defined based on average intakes of food groups per meal disaggregated from all food sources. 2011-12 National Nutrition and Physical Activity Survey. Australian people (n12153) aged 2 years or above. Overall, breakfast was the smallest meal of the day, typically consisting of grains, dairy products and fruit. Lunch was the second largest meal, consisting mostly of grains, non-starchy vegetables and meat/poultry/fish. The largest meal was dinner, comprising meat/poultry/fish, vegetables (starchy and non-starchy), grains and often including discretionary beverages (children) or alcohol (adults). The main food groups consumed at snacking occasions were dairy, fruit, discretionary foods and beverages (including alcohol for adults). The most frequently consumed meat types were beef and chicken at dinner and ham at lunch. Non-starchy vegetables were accompanying foods for red meat, poultry and fish/seafood consumed in varying portion sizes, but did not accompany processed meat. The present study considered meat, poultry and fish as the meal centre and their accompaniments of other food groups at different eating occasions. These findings expand the background evidence for health professionals developing meal-based framework/guidelines and public health messages.

There are currently no national standards for school lunch period length and little is known about the association between the amount of time students have to eat and school food selection and consumption. Our aim was to examine plate-waste measurements from students in the control arm of the Modifying Eating and Lifestyles at School study (2011 to 2012 school year) to determine the association between amount of time to eat and school meal selection and consumption. We used a prospective study design using up to six repeated measures among students during the school year. One thousand and one students in grades 3 to 8 attending six participating elementary and middle schools in an urban, low-income school district where lunch period lengths varied from 20 to 30 minutes were included. School food selection and consumption were collected using plate-waste methodology. Logistic regression and mixed-model analysis of variance was used to examine food selection and consumption. Compared with meal-component selection when students had at least 25 minutes to eat, students were significantly less likely to select a fruit (44% vs 57%; Peat. There were no significant differences in entrée, milk, or vegetable selections. Among those who selected a meal component, students with eat consumed 13% less of their entrée (Peat. During the school year, a substantial number of students had insufficient time to eat, which was associated with significantly decreased entrée, milk, and vegetable consumption compared with students who had more time to eat. School policies that encourage lunches with at least 25 minutes of seated time might reduce food waste and improve dietary intake. Copyright © 2016 Academy of Nutrition and Dietetics.

Full Text Available Iron status is associated with cognitive performance and intervention trials show that iron supplementation improves mental function in iron-deficient adults. However, no studies have tested the efficacy of naturally iron-rich food in this context. This investigation measured the hematologic and cognitive responses to moderate beef consumption in young women. Participants (n = 43; age 21.1 ± 0.4 years were randomly assigned to a beef or non-beef protein lunch group [3-oz (85 g, 3 times weekly] for 16 weeks. Blood was sampled at baseline, and weeks 8 and 16, and cognitive performance was measured at baseline and week 16. Body iron increased in both lunch groups (p < 0.0001, with greater improvement demonstrated in women with lower baseline body iron (p < 0.0001. Body iron had significant beneficial effects on spatial working memory and planning speed (p < 0.05, and ferritin responders (n = 17 vs. non-responders (n = 26 showed significantly greater improvements in planning speed, spatial working memory strategy, and attention (p < 0.05. Lunch group had neither significant interactions with iron status nor consistent main effects on test performance. These findings support a relationship between iron status and cognition, but do not show a particular benefit of beef over non-beef protein consumption on either measure in young women.

The energy density (ED; kcal/g) of foods, when manipulated in the laboratory, affects short-term energy intake. The aim of this study was to examine if, when given a choice, dietary ED (foods only) and energy intake (expressed as a percentage of subjects' estimated daily energy requirement; EER) at a self-selected, single meal differ for teens born with a different familial predisposition to obesity and as a function of their sex. Subjects (13 males, 17 females) were 12years of age and born at high risk (HR; n=15) or low risk (LR; n=15) for obesity based on maternal pre-pregnancy body mass index (BMI; kg/m(2)). The buffet meal, served for lunch and consumed ad libitum, consisted of a variety of foods and beverages with a range in ED. HR subjects consumed a more energy-dense meal (foods only) than LR subjects (1.84 vs. 1.42kcal/g; P=0.02) and males consumed a more energy-dense meal than females (1.83 vs. 1.43kcal/g; P=0.03). Total energy intake, when expressed as a percentage of subjects' daily EER, did not differ between HR and LR subjects (42% vs. 33%; P=0.16). Males, compared to females, consumed ~59% more energy from foods and beverages during the meal (46 vs. 29%; P=0.008). During a single multi-item lunch meal, teens with a familial predisposition to obesity and males, independent of their obesity risk status, self-selected a more energy-dense meal. Familial risk for obesity, through either genetic or environmental pathways, may facilitate a more energy-dense diet.

The purpose of this study was to assess whether the availability of a product sample of an unfamiliar low-fat or fruit and vegetable products stimulates choice for this product among food neophobic young adults. The study had a 2 (experimental vs. control group) by 4 (low-fat bread spread, low-fat cheese, fruit juice, fruit and vegetable juice) between subjects design with a pre-and post-experiment questionnaire. The study was conducted in restaurant rooms of several educational institutions in the Netherlands among a convenience sample of 197 food neophobic young adults aged 17-25 years. A small bite or sip-sized sample of the target product was provided as an intervention. The effect measure was choice of either an unfamiliar healthful food product or a traditional food product. Offering a sample of an unfamiliar healthful food product resulted in 51% of the participants in the experimental group choosing this product vs. 36.4% in the control group. Providing food product samples seems to be a promising strategy in healthy diet promotion programs for food neophobic young adults to increase first-time trial of unfamiliar low-fat and fruit and vegetable products.

A New Nordic Diet (NND) was developed in the context of the Danish OPUS Study (Optimal well-being, development and health for Danish children through a healthy New Nordic Diet). Health, gastronomic potential, sustainability and Nordic identity were crucial principles of the NND. The aim of the present study was to investigate the effects of serving NND school meals compared with the usual packed lunches on the dietary intake of NND signature foods. For two 3-month periods, 834 Danish children aged 8-11 years received NND school meals or their usual packed lunches brought from home (control) in random order. The entire diet was recorded over 7 consecutive days using a validated Web-based Dietary Assessment Software for Children. The NND resulted in higher intakes during the entire week (% increase) of root vegetables (116 (95 % CI 1·93, 2·42)), cabbage (26 (95 % CI 1·08, 1·47)), legumes (22 (95 % CI 1·06, 1·40)), herbs (175 (95 % CI 2·36, 3·20)), fresh berries (48 (95 % CI 1·13, 1·94)), nuts and seeds (18 (95 % CI 1·02, 1·38)), lean fish and fish products (47 (95 % CI 1·31, 1·66)), fat fish and fish products (18 (95 % CI 1·02, 1·37)) and potatoes (129 (95 % CI 2·05, 2·56)). Furthermore, there was a decrease in the number of children with zero intakes when their habitual packed lunches were replaced by NND school meals. In conclusion, this study showed that the children increased their intake of NND signature foods, and, furthermore, there was a decrease in the number of children with zero intakes of NND signature foods when their habitual packed lunches were replaced by school meals following the NND principles.

Cohen, Juliana F.W.; Jahn, Jaquelyn L.; Richardson, Scott; Cluggish, Sarah A.; Parker, Ellen; Rimm, Eric B.

2015-01-01

Background There are currently no national standards for school lunch period lengths and little is known about the association between the amount of time students have to eat and school food selection and consumption. Objectives To examine plate waste measurements from students in the control arm from the MEALS study (2011-2012 school year) for the association of the amount of time to eat with school meal selection and consumption. Design Prospective study using up to six repeated measures among students over the school year. Participants/Setting 1001 students in grades 3-8 attending 6 participating elementary/middle schools in an urban, low-income school district where lunch period lengths varied from 20-30 minutes. Main Outcome Measures School food selection and consumption were collected using plate waste methodology. Statistical Analyses Performed Logistic regression and mixed-model ANOVA was used to examine food selection and consumption. Results Compared with meal component selection when students had at least 25 minutes to eat, students were significantly less likely to select a fruit (44% vs. 57%; p=0.0001) compared with when students had fewer than 20 minutes to eat. There were no significant differences in entrée, milk, or vegetable selection. Among those who selected a meal component, students with fewer than 20 minutes to eat consumed 13% less of their entrée (peat. Conclusions Over the school year, a substantial number of students had insufficient time to eat, which was associated with significantly decreased entrée, milk, and vegetable consumption compared with students who had more time to eat. School policies that encourage lunches with at least 25 minutes of seated time may reduce food waste and improve dietary intake. PMID:26372337

Food waste and food processing waste for biohydrogen production: a review.

Science.gov (United States)

Yasin, Nazlina Haiza Mohd; Mumtaz, Tabassum; Hassan, Mohd Ali; Abd Rahman, Nor'Aini

2013-11-30

Food waste and food processing wastes which are abundant in nature and rich in carbon content can be attractive renewable substrates for sustainable biohydrogen production due to wide economic prospects in industries. Many studies utilizing common food wastes such as dining hall or restaurant waste and wastes generated from food processing industries have shown good percentages of hydrogen in gas composition, production yield and rate. The carbon composition in food waste also plays a crucial role in determining high biohydrogen yield. Physicochemical factors such as pre-treatment to seed culture, pH, temperature (mesophilic/thermophilic) and etc. are also important to ensure the dominance of hydrogen-producing bacteria in dark fermentation. This review demonstrates the potential of food waste and food processing waste for biohydrogen production and provides a brief overview of several physicochemical factors that affect biohydrogen production in dark fermentation. The economic viability of biohydrogen production from food waste is also discussed. Copyright © 2013 Elsevier Ltd. All rights reserved.

Strategies and willingness of rural restaurateurs to promote healthy foods.

Science.gov (United States)

Benson, W

1995-01-01

Nutritionists need to understand the willingness of restaurateurs to prepare and sell healthy foods, as Canadians frequently eat meals at food services. The lunch trade restaurants under the jurisdiction of a rural and semi-rural Alberta health unit were surveyed by telephone. Two thirds of the restaurants were family-style and had 100 seats or fewer. Five of 20 healthy foods were rated as difficult to serve, due to: lack of customer demand; lack of food availability; and the need to maintain the quality of fresh vegetables, fruits and milk products. Many restaurateurs are willing to change internally by training staff (88%) and by trying new recipes (84%). Staff education materials perceived to be helpful by 80% of restaurateurs included video/audio tapes, information sheets and posters. Restaurateurs were most willing to use menu inserts (76%), table tents (68%) and door decals (72%) to promote healthy foods. Nutrition services should focus on how restaurants can make changes to include healthy foods through food preparation and menu items.

As obesity has become a pressing health issue for American children, greater attention has been focused on how schools can be used to improve how students eat. Previously, we piloted the use of small prizes in an elementary school cafeteria to improve healthful food selection. We hoped to increase healthful food selection in all the elementary schools of a small school district participating in the United States Department of Agriculture Lunch Program by offering prizes to children who selected a Power Plate (PP), which consisted of an entrée with whole grains, a fruit, a vegetable, and plain low-fat milk. In this study, the PP program was introduced to 3 schools sequentially over an academic year. During the kickoff week, green, smiley-faced emoticons were placed by preferred foods, and children were given a prize daily if they chose a PP on that day. After the first week, students were given a sticker or temporary tattoo 2 days a week if they selected a PP. Combining data from the 3 schools in the program, students increased PP selection from 4.5% at baseline to 49.4% (p small prizes as rewards dramatically improves short-term healthful food selection in elementary school children.

Food legume production in China

Directory of Open Access Journals (Sweden)

Ling Li

2017-04-01

Full Text Available Food legumes comprise all legumes grown for human food in China as either dry grains or vegetables, except for soybean and groundnut. China has a vast territory with complex ecological conditions. Rotation, intercropping, and mixed cropping involving pulses are normal cropping systems in China. Whether indigenous or introduced crops, pulses have played an important role in Chinese cropping systems and made an important contribution to food resources for humans since ancient times. The six major food legume species (pea, faba bean, common bean, mung bean, adzuki bean, and cowpea are the most well-known pulses in China, as well as those with more local distributions; runner bean, lima bean, chickpea, lentil, grass pea, lupine, rice bean, black gram, hyacinth bean, pigeon pea, velvet bean, winged bean, guar bean, sword bean, and jack bean. China has remained the world's leading producer of peas, faba beans, mung beans, and adzuki beans in recent decades, as documented by FAO statistics and China Agriculture Statistical Reports. The demand for food legumes as a healthy food will markedly increase with the improvement of living standards in China. Since China officially joined the World Trade Organization (WTO in 2001, imports of pea from Canada and Australia have rapidly increased, resulting in reduced prices for dry pea and other food legumes. With reduced profits for food legume crops, their sowing area and total production has decreased within China. At the same time, the rising consumer demand for vegetable food legumes as a healthy food has led to attractive market prices and sharp production increases in China. Vegetable food legumes have reduced growing duration and enable flexibility in cropping systems. In the future, production of dry food legumes will range from stable to slowly decreasing, while production of vegetable food legumes will continue to increase.

Afternoon nap and bright light exposure improve cognitive flexibility post lunch.

Directory of Open Access Journals (Sweden)

Full Text Available Beneficial effects of napping or bright light exposure on cognitive performance have been reported in participants exposed to sleep loss. Nonetheless, few studies investigated the effect of these potential countermeasures against the temporary drop in performance observed in mid-afternoon, and even less so on cognitive flexibility, a crucial component of executive functions. This study investigated the impact of either an afternoon nap or bright light exposure on post-prandial alterations in task switching performance in well-rested participants. Twenty-five healthy adults participated in two randomized experimental conditions, either wake versus nap (n=15, or bright light versus placebo (n=10. Participants were tested on a switching task three times (morning, post-lunch and late afternoon sessions. The interventions occurred prior to the post-lunch session. In the nap/wake condition, participants either stayed awake watching a 30-minute documentary or had the opportunity to take a nap for 30 minutes. In the bright light/placebo condition, participants watched a documentary under either bright blue light or dim orange light (placebo for 30 minutes. The switch cost estimates cognitive flexibility and measures task-switching efficiency. Increased switch cost scores indicate higher difficulties to switch between tasks. In both control conditions (wake or placebo, accuracy switch-cost score increased post lunch. Both interventions (nap or bright light elicited a decrease in accuracy switch-cost score post lunch, which was associated with diminished fatigue and decreased variability in vigilance. Additionally, there was a trend for a post-lunch benefit of bright light with a decreased latency switch-cost score. In the nap group, improvements in accuracy switch-cost score were associated with more NREM sleep stage N1. Thus, exposure to bright light during the post-lunch dip, a countermeasure easily applicable in daily life, results in similar

Healthier meat products as functional foods.

Science.gov (United States)

Decker, Eric A; Park, Yeonhwa

2010-09-01

A promising approach to improving health care would be to produce a healthier food supply as a preventive health care strategy. The food supply could be improved by producing functional foods that have nutritional profiles that are healthier than conventional products. However, production of functional foods is not always easily accomplished since they must also taste good, be convenient and reasonably priced so that consumers will regularly purchase and use the products. Meats have great potential for delivering important nutrients such as fatty acids, minerals, dietary fiber, antioxidants and bioactive peptides into the diet. However, to produce successful products with these ingredients, technologies must be developed to increase their stability and decrease their flavor impact on muscle foods. In addition, many regulatory hurdles must be overcome for the commercial production of meats with added nutrients. These include redefinition of standard of identities and policies that allow front of the package nutritional claims. Without these regulatory changes, production of healthier meat products won't become a reality since these products would not have a competitive advantage over unfortified meats.

Reproducibility and validity testing of appetite ratings and energy intakes are needed in experimental and natural settings. Eighteen healthy young women ate a standardized breakfast for 8 days. Days 1 and 8, they rated their appetite (Hunger, Fullness, Desire to Eat, Prospective Food Consumption (PFC)) over a 3.5 h period using visual analogue scales, consumed an ad libitum lunch, left the research center and recorded food intake for the remainder of the day. Days 2-7, participants rated their at-home Hunger at 0 and 30 min post-breakfast and recorded food intake for the day. Total area under the curve (AUC) over the 180 min period before lunch, and energy intakes were calculated. Reproducibility of satiety measures between days was evaluated using coefficients of repeatability (CR), coefficients of variation (CV) and intra-class coefficients (ri). Correlation analysis was used to examine validity between satiety measures. AUCs for Hunger, Desire to Eat and PFC (ri = 0.73-0.78), ad libitum energy intakes (ri = 0.81) and total day energy intakes (ri​ = 0.48) were reproducible; fasted ratings were not. Average AUCs for Hunger, Desire to Eat and PFC, Desire to Eat at nadir and PFC at fasting, nadir and 180 min were correlated to total day energy intakes (r = 0.50-0.77, P < 0.05), but no ratings were correlated to lunch consumption. At-home Hunger ratings were weakly reproducible but not correlated to reported total energy intakes. Satiety ratings did not concur with next meal intake but PFC ratings may be useful predictors of intake. Overall, this study adds to the limited satiety research on women and challenges the accepted measures of satiety in an experimental setting. Copyright © 2016 Elsevier Ltd. All rights reserved.

Claiming health in food products

2013-01-01

Health-related information is increasingly used on food products to convey their benefits. Health claims as a subcategory of these messages link the beneficial component, functions or health outcomes with specific products. For consumers, health claims seem to carry the message of increased...... healthiness, but not necessarily making the product more appealing. The wording of the claim seems to have little impact on claim perception, yet the health image of carrier products is important. From consumer-related factors the relevance and attitudes towards functional foods play a role, whereas socio......-demographic factors have only minor impact and the impact seems to be case-dependent. Familiarity with claims and functional foods increase perceived healthiness and acceptance of these products. Apparently consumers make rather rational interpretations of claims and their benefits when forced to assess...

Non-dairy probiotic food products: An emerging group of functional foods.

Min, Min; Bunt, Craig R; Mason, Susan L; Hussain, Malik A

2018-04-09

The functional food sector has shown tremendous growth in recent years with the application of probiotic bacteria as "food additives". The utilization of probiotic bacteria in food presents many challenges related to their growth, survival, viability, stability and functionality in food processing, storage and consumption as well as changes of sensory characteristics of probiotic foods. Although dairy foods are currently the most common food carrier to deliver probiotics, an increasing number of non-dairy food matrices exhibit potential for delivery of probiotics. This review provides more recent insight into the emergence of non-dairy probiotics products, the interactions between probiotics and different food matrices and the challenges in developing such products. Some of the technical issues are also reviewed and discussed. These issues include the efficacy of probiotic bacteria in non-chilled, low pH or high water activity foods; the potential loss of bacterial viability, additionally unwanted fermentation and changes of the sensory characteristics of food products which may result in poor microbiological quality and low acceptability to consumers.

Nutritional quality of food items on fast-food 'kids' menus': comparisons across countries and companies.

2014-10-01

To compare energy (calories), total and saturated fats, and Na levels for 'kids' menu' food items offered by four leading multinational fast-food chains across five countries. A content analysis was used to create a profile of the nutritional content of food items on kids' menus available for lunch and dinner in four leading fast-food chains in Australia, Canada, New Zealand, the UK and the USA. Food items from kids' menus were included from four fast-food companies: Burger King, Kentucky Fried Chicken (KFC), McDonald's and Subway. These fast-food chains were selected because they are among the top ten largest multinational fast-food chains for sales in 2010, operate in high-income English-speaking countries, and have a specific section of their restaurant menus labelled 'kids' menus'. The results by country indicate that kids' menu foods contain less energy (fewer calories) in restaurants in the USA and lower Na in restaurants in the UK. The results across companies suggest that kids' menu foods offered at Subway restaurants are lower in total fat than food items offered at Burger King and KFC, and food items offered at KFC are lower in saturated fat than items offered at Burger King. Although the reasons for the variation in the nutritional quality of foods on kids' menus are not clear, it is likely that fast-food companies could substantially improve the nutritional quality of their kids' menu food products, translating to large gains for population health.

Biofuels versus food production: Does biofuels production increase food prices?

International Nuclear Information System (INIS)

Ajanovic, Amela

2011-01-01

Rapidly growing fossil energy consumption in the transport sector in the last two centuries caused problems such as increasing greenhouse gas emissions, growing energy dependency and supply insecurity. One approach to solve these problems could be to increase the use of biofuels. Preferred feedstocks for current 1st generation biofuels production are corn, wheat, sugarcane, soybean, rapeseed and sunflowers. The major problem is that these feedstocks are also used for food and feed production. The core objective of this paper is to investigate whether the recent increase of biofuels production had a significant impact on the development of agricultural commodity (feedstock) prices. The most important impact factors like biofuels production, land use, yields, feedstock and crude oil prices are analysed. The major conclusions of this analysis are: In recent years the share of bioenergy-based fuels has increased moderately, but continuously, and so did feedstock production, as well as yields. So far, no significant impact of biofuels production on feedstock prices can be observed. Hence, a co-existence of biofuel and food production seems possible especially for 2nd generation biofuels. However, sustainability criteria should be seriously considered. But even if all crops, forests and grasslands currently not used were used for biofuels production it would be impossible to substitute all fossil fuels used today in transport.

This paper explores the political, economic, and social life of Nelson Mandela through his food choices from 1918 to the present. A description of the minutiae of one particular 1950s Sunday lunch is used to examine the broader role of first colonial and later apartheid legislation in determining the dietary choices and options of South Africans past and present. How such policies shaped attitudes and access to Nelson Mandela’s ancestral Xhosa cuisine is assessed. The long-term cultural, economic, and political impact of a lack of access to core indigenous African ingredients is evaluated. Most of all this paper offers a snapshot portrayal of two families (one white, one black) trying to sustain a normal friendship within a grossly abnormal society.

Availability of healthier options in traditional and nontraditional rural fast-food outlets

McIntosh Alex

2008-11-01

Full Text Available Abstract Background Food prepared away from home has become increasingly popular to U.S. families, and may contribute to obesity. Sales have been dominated by fast food outlets, where meals are purchased for dining away from home or in the home. Although national chain affiliated fast-food outlets are considered the main source for fast food, fast foods are increasingly available in convenience stores and supermarkets/grocery stores. In rural areas, these nontraditional fast-food outlets may provide most of the opportunities for procurement of fast foods. Methods Using all traditional and nontraditio nal fast-food outlets identified in six counties in rural Texas, the type and number of regular and healthiermenu options were surveyed using on-site observation in all food venues that were primarily fast food, supermarket/grocery store, and convenience store and compared with 2005 Dietary Guidelines. Results Traditional fast-food outlets represented 84 (41% of the 205 opportunities for procurement of fast food; 109 (53.2% were convenience stores and 12 (5.8% supermarkets/grocery stores. Although a s imilar variety of regular breakfast and lunch/dinner entrées were available in traditional fast-food outlets and convenience stores, the variety of healthier breakfast and lunch/dinner entrées was significantly greater in fast food outlets. Compared with convenience stores, supermarkets/grocery stores provided a greater variety of regular and healthier entrées and lunch/dinner side dishes. Conclusion Convenience stores and supermarkets/grocery stores more than double the potential access to fast foods in this rural area than traditional fast-food outlets alone; however, traditional fast food outlets offer greater opportunity for healthier fast food options than convenience stores. A complete picture of fast food environment and the availability of healthier fast food options are essential to understand environmental influences on diet and health

Full Text Available Yeasts have been known to humans for thousands of years as they have been used in traditional fermentation processes like wine, beer and bread making. Today, yeasts are also used as alternative sources of high nutritional value proteins, enzymes and vitamins, and have numerous applications in the health food industry as food additives, conditioners and flavouring agents, for the production of microbiology media and extracts, as well as livestock feeds. Modern scientific advances allow the isolation, construction and industrial production of new yeast strains to satisfy the specific demands of the food industry. Types of commercial food grade yeasts, industrial production processes and raw materials are highlighted. Aspects of yeast metabolism, with respect to carbohydrate utilization, nutritional aspects and recent research advances are also discussed.

Irradiated food for immunocompromised people

International Nuclear Information System (INIS)

Narvaiz, Patricia

2005-01-01

Immune-compromise is a condition in which the natural defenses against diseases are dimished; several situations can be cited as examples, including mis nourishment, pregnancy, young and old age. This enhances the probability of suffering microbial diseases, caused by food borne pathogens. Traditionally, immune-suppressed patients in hospitals were isolated from the environment, being their food sterilized by different treatments, including irradiation. At present the medical opinion differs from this approach due to the costs and specialized requirements, uncertainties about the clinical benefits, and psychological convenience. So, the tendency nowadays seems to move, when the patient's condition allows it, from 'sterile diets' to 'low microbe diets' (or 'clean diets'). At the National Atomic Energy Commission, Argentina, under Coordinated Research Programmes of the Food and Environmental Preservation Section, International Atomic Energy Agency, in which 14 countries participated, treatments at pasteurizing doses were studied to widen the meals availability for vulnerable persons, to include some products usually considered as 'high risk' , but nutritionally or psychologically adequate. In a first experience, nutritionists working at the corresponding Service in a Buenos Aires hospital elaborated diets suitable for patients with different immune-compromise degrees, and advised on the interesting meal types to be studied. In a second experience, advanced nutrition students of the Entre Rios University performed a sensory evaluation in which 44 immune- compromised patients at the Jose de San Martin Clinical School Hospital, Buenos Aires, tasted a whole irradiated lunch composed of meals usually forbidden due to high microbial risk, though highly desired. The patients evaluated this lunch with high scores and showed enthusiastic towards the irradiation treatment. This preservation treatment could not only be useful to supply hospitals but also supermarkets. (author)

Federal regulation mandates that the US National School Lunch Program nutrition standards align with the Dietary Guidelines for Americans. As students consume a substantial proportion of their nutrition during school lunch, increasing access to healthy foods is proposed to improve student dietary outcomes. The purpose of this review is to assess whether policy changes impacted food-consumption behaviors of students during periods when (1) school wellness policies were implemented (2006-2007); (2) the Healthy, Hunger-Free Kids Act was passed (2010-2012); and (3) the Healthy, Hunger-Free Kids Act was implemented (2012-present). PubMed, Web of Science, and Science Direct were searched for primary research studies. Policy evaluations and interventions implemented from 2006 to 2016 were included. A total of 31 studies evaluating plate waste, dietary intake, food selection, and/or purchasing patterns were identified and reviewed. Fourteen of 19 intervention and longitudinal observation studies reported improved food-consumption behaviors (increased selection, intake, and sales of healthy foods, and decreased plate waste). Only 2 of 12 one-time observation studies reported food-consumption behaviors meeting target nutrition standards. The majority of studies indicated that increasing access to healthy foods during school lunch improved students' dietary intakes. Challenges related to study design, adaptation period, quality of foods, and policy implementation likely affect a school lunch program's ability to impact students' food-consumption behaviors. Ongoing evaluation of these programs is warranted. © The Author(s) 2017. Published by Oxford University Press on behalf of the International Life Sciences Institute. All rights reserved.

Consumption of sugar-sweetened beverages may be one of the dietary causes of metabolic disorders, such as obesity. Therefore, substituting sugar with low-calorie sweeteners may be an efficacious weight management strategy. We tested the effect of preloads containing stevia, aspartame, or sucrose on food intake, satiety, and postprandial glucose and insulin levels. Design: 19 healthy lean (BMI = 20.0 – 24.9) and 12 obese (BMI = 30.0 – 39.9) individuals 18 to 50 years old completed three separate food test days during which they received preloads containing stevia (290 kcal), aspartame (290 kcal), or sucrose (493 kcal) before the lunch and dinner meal. The preload order was balanced, and food intake (kcal) was directly calculated. Hunger and satiety levels were reported before and after meals, and every hour throughout the afternoon. Participants provided blood samples immediately before and 20 minutes after the lunch preload. Despite the caloric difference in preloads (290 vs. 493 kcals), participants did not compensate by eating more at their lunch and dinner meals when they consumed stevia and aspartame versus sucrose in preloads (mean differences in food intake over entire day between sucrose and stevia = 301 kcal, p Stevia preloads significantly lowered postprandial glucose levels compared to sucrose preloads (p stevia and aspartame preloads, participants did not compensate by eating more at either their lunch or dinner meal and reported similar levels of satiety compared to when they consumed the higher calorie sucrose preload.

Food Production and Processing Considerations of Allergenic Food Ingredients: A Review

Science.gov (United States)

Alvarez, Pedro A.; Boye, Joyce I.

2012-01-01

Although most consumers show no adverse symptoms to food allergens, health consequences for sensitized individuals can be very serious. As a result, the Codex General Standard for the Labelling of Prepackaged Foods has specified a series of allergenic ingredients/substances requiring mandatory declaration when present in processed prepackaged food products. Countries adhering to international standards are required to observe this minimum of eight substances, but additional priority allergens are included in the list in some countries. Enforcement agencies have traditionally focused their effort on surveillance of prepackaged goods, but there is a growing need to apply a bottom-up approach to allergen risk management in food manufacturing starting from primary food processing operations in order to minimize the possibility of allergen contamination in finished products. The present paper aims to review food production considerations that impact allergen risk management, and it is directed mainly to food manufacturers and policy makers. Furthermore, a series of food ingredients and the allergenic fractions identified from them, as well as the current methodology used for detection of these allergenic foods, is provided.

Liu, Junguo; Ma, Kun; Ciais, Philippe; Polasky, Stephen

2016-07-22

Reactive nitrogen (N) is created in order to sustain food production, but only a small fraction of this N ends up being consumed as food, the rest being lost to the environment. We calculated that the total N input (TN) of global food production was 171 Tg N yr(-1) in 2000. The production of animal products accounted for over 50% of the TN, against 17% for global calories production. Under current TN per unit of food production and assuming no change in agricultural practices and waste-to-food ratios, we estimate that an additional TN of 100 Tg N yr(-1) will be needed by 2030 for a baseline scenario that would meet hunger alleviation targets for over 9 billion people. Increased animal production will have the largest impact on increasing TN, which calls for new food production systems with better N-recycling, such as cooperation between crop and livestock producing farms. Increased N-use efficiency, healthier diet and decreased food waste could mitigate this increase and even reduce TN in 2030 by 8% relative to the 2000 level. Achieving a worldwide reduction of TN is a major challenge that requires sustained actions to improve nitrogen management practices and reduce nitrogen losses into the environment.

Soil Erosion Threatens Food Production

Directory of Open Access Journals (Sweden)

Michael Burgess

2013-08-01

Full Text Available Since humans worldwide obtain more than 99.7% of their food (calories from the land and less than 0.3% from the oceans and aquatic ecosystems, preserving cropland and maintaining soil fertility should be of the highest importance to human welfare. Soil erosion is one of the most serious threats facing world food production. Each year about 10 million ha of cropland are lost due to soil erosion, thus reducing the cropland available for world food production. The loss of cropland is a serious problem because the World Health Organization and the Food and Agricultural Organization report that two-thirds of the world population is malnourished. Overall, soil is being lost from agricultural areas 10 to 40 times faster than the rate of soil formation imperiling humanity’s food security.

To categorize and assess all foods, beverages and ingredients provided over one week at Australian long day care (LDC) centres according to four levels of food processing and to assess the contribution of Na from each level of processing. Cross-sectional. Menus for lunch, morning and afternoon snacks were collected from LDC centres. The level of food processing of all foods, beverages and ingredients was assessed utilizing a four-level food processing classification system: minimally processed (MP), processed culinary ingredients (PCI), processed (P) and ultra-processed (ULP). A total of thirty-five menus (lunch, n 35; snacks, n 70) provided to 1-5-year-old children were collected from seven LDC centres. Proportions of foodstuffs classified as MP, PCI, P and ULP were 54, 10, 15 and 21 %, respectively. All lunches were classified as MP. ULP foods accounted for 6 % of morning snacks; 41 % of afternoon snacks. Mean daily amount of Na provided per child across all centres was 633 (sd 151) mg. ULP foods provided 40 % of Na, followed by P (35 %), MP (23 %) and PCI (2 %). Centres provided foods resulting in a mean total daily Na content that represented 63 % of the recommended Upper Level of Intake for Na in this age group. A significant proportion of ULP snack foods were included, which were the major contributor to total daily Na intake. Replacement of ULP snack foods with MP lower-Na alternatives is recommended.

The aim of the worksite study is to elucidate the strain reducing impact of different forms of spending lunch breaks. With the help of the so-called silent room cabin concept, it was possible to induce a lunch-break relaxation opportunity that provided visual and territorial privacy. To evaluate the proposed effects, 14 call center agents were assigned to either 20 min progressive muscle relaxation (PMR) or small-talk (ST) break groups. We analyzed the data in a controlled trial for a period of 6 months (every 2 months four measurements a day at 12:00, 13:00, 16:00, 20:00) using independent observer and self-report ratings of emotional, mental, motivational, and physical strain. Results indicated that only the PMR break reduced postlunchtime and afternoon strain. Although further intervention research is required, our results suggest that PMR lunch break may sustainable reduce strain states in real worksite settings. Copyright 2010 APA, all rights reserved.

To assess the agreement of posted menus with foods served to 3- to 5-year-old children attending federal Child and Adult Care Food Program (CACFP)-enrolled facilities, and the degree to which the facilities met the new meal patterns and best practices. On-site observations and menu coding. Nine early care and education centers. Agreement of posted menus with foods served, and comparison of foods served and consumed with the new CACFP meal guidelines and best practices. Data were compiled for each meal (breakfast, lunch, and snacks). Frequencies and percentages of agreement with the posted menu (coded matches, substitutions, additions, and omissions) were calculated for each food component in the CACFP menu guidelines. Menu total match was created by summing the menu match plus acceptable substitutions. Menus were compared with the new CACFP meal guidelines and best practices. The match between the posted menus and foods actually served to children at breakfast, lunch, and snack was high when the acceptable menu substitutions were considered (approximately 94% to 100% total match). Comparing the menus with the new meal guidelines and best practices, the 1 guideline that was fully implemented was serving only unflavored, low-fat, or 1% milk; fruit and vegetable guidelines were partially met; fruit juice was not served often, nor were legumes; the guideline for 1 whole grain-rich serving/d was not met; and regular beef and full-fat cheese products were commonly served. Early care and education centers enrolled in CACFP provided meals that met the current CACFP guidelines. Some menu improvements are needed for the centers to meet the new guidelines and best practices. Copyright © 2018 Society for Nutrition Education and Behavior. Published by Elsevier Inc.

Background Within the past decade there has been increasing attention to the role of fast food in the American diet, including a rise in legislative and media-based efforts that address the healthfulness of fast food. However, no studies have been undertaken to evaluate changes in the energy content of fast-food chain restaurant menu items during this period. Purpose To examine changes in the energy content of lunch/dinner menu offerings at eight of the leading fast-food chain restaurants in the U.S. between 1997/1998 and 2009/2010. Methods Menu offerings and nutrient composition information were obtained from archival versions of the University of Minnesota Nutrition Coordinating Center Food and Nutrient Database. Nutrient composition information for items was updated biannually. Changes in median energy content of all lunch/dinner menu offerings and specific categories of menu items among all restaurants and for individual restaurants were examined. Data were collected between 1997 and 2010 and analysis was conducted in 2011. Results Spanning 1997/1998 and 2009/2010, the number of lunch/dinner menu items offered by the restaurants in the study increased by 53%. Across all menu items, the median energy content remained relatively stable over the study period. Examining specific food categories, the median energy content of desserts and condiments increased, the energy content of side items decreased, and energy content of entrees and drinks remained level. Conclusions While large increases in the number of menu items were observed, there have been few changes in the energy content of menu offerings at the leading fast-food chain restaurants examined in this study.

Nutritionally promoted foods are now available at fast-food establishments. Little is known about their popularity, who is purchasing them, or their impact on dietary intake. Our study aimed to determine: how often nutritionally promoted fast foods were purchased; the demographic characteristics of people purchasing these foods; and if purchasing these foods resulted in reduced energy, and increased vegetable, content of lunches compared with those who purchased traditional fast foods. A survey collecting lunchtime fast-food purchases and demographic details was administered over two months. Nutritionally promoted products included the McDonalds' 'Heart Foundation Tick Approved' range and Subway's 'Six grams of fat or less' range. Energy and vegetable contents were estimated using information from fast-food companies' websites. Differences in demographics, energy and vegetable contents between individuals purchasing nutritionally promoted and traditional lunches were assessed using χ2 and t tests. Queensland, Australia. Lunchtime diners aged over 16 years at Subway and McDonalds. Surveys were collected from 927 respondents (58 % male, median age 25 (range 16-84) years; 73 % response rate). Only 3 % (n 24/910) of respondents who ordered a main option had purchased a nutritionally promoted item. Purchasers of nutritionally promoted foods were ∼13 years older, predominantly female (79 %), and more often reported involvement in a health-related profession (29 % v. 11 %) than purchasers of traditional foods (P < 0·05). Purchasers of nutritionally promoted foods ordered 1·5 fewer megajoules and 0·6 more vegetable servings than purchasers of traditional foods (P < 0·05). Nutritionally promoted fast foods may reduce lunchtime energy content, however these foods were infrequently chosen.

Full Text Available Abundant knowledge of the significance of food quality for all human living functions as well as growing human population and the occurrence of world "hidden hunger", directed food producers toward new production processes of and new product development that must satisfy the specific needs of different categories of consumers. The differences are reflected in sex age, religious affiliation, activity, health, social status etc. "Organic", "natural, minimal processing, functional (and often called "therapeutical" food nowadays represents the key interest of nutritionists, physicians and food producers. Such food should have a beneficial influence on human health, besides satisfying the nutritive and energetic necessities, by protective, prophylactic and healing performance. This paper discusses facts about the influence of food on human health, problems of malnutrition in developing and developed countries, presents states of food production in the world and in Yugoslavia, legislation and regulations on nourishment and food production, the disadvantages of former concepts of development of this production and possible directions of future trends with a particular review on functional food production.

Full Text Available The article discusses agrofuels production as a reason for increasing the dissociation between the human being, the land and the environment, considering the issues involving food security and food sovereignty. By using the deductive method, it aims to demonstrate that the growing distance between men and land is one of the results determined by capitalism, which is based on exploitation and maximized land production in order to obtain profit, interfering thereas in national food security and food sovereignty. Thus, it first deals with the relation between the human being, land, the environment, economy, State and politics, focusing on environmental  human  rights  protagonism  such  as  side  for  recognizing  and  developing /enveloping fundamental rights material. Secondly, it brings agrofuels production scenario and its relation with food security and sovereignty. Finally, it concepts food security and food sovereignty, establishing its differences in order to permit the build up a solid reality that is also able to secure their implement in an economy of family polycultural basis even if there is an opposite side oriented by capitalism and protected by State, specially in which concerns to productions and environmental excessive exploitation. The article concludes that to secure fundamental rights the being needs to recognize oneself as part of the environment in order to develop a significant State behavior which will reflect on economical politics that favors food security and food sovereignty.

Eat lunch first or play first? Inconsistent associations with fruit and vegetable consumption in elementary school.

2015-04-01

Scheduling play before eating lunch has been suggested as a relatively simple environmental strategy to increase fruit and vegetable (FV) intake among elementary school students. However, the few small studies to date have had mixed findings. The primary aim of this observational study was to evaluate the possible relationship between the relative order of play and eating and students' lunch intake of FV. A secondary aim was to examine whether any differences existed in this relationship by student sex, ethnicity, language spoken at home, and school lunch source. A diary-assisted 24-hour recall was collected during the 2011-2012 school year from 2,167 fourth- and fifth-graders attending 31 elementary schools in California. The association of play before eating with FV intake was estimated using Generalized Estimation Equations. Overall, lunch FV intake was not significantly higher for students who had a play-before-eating vs a play-after-eating lunch schedule at school. However, variables included in the model showed significant interaction with play before eating, resulting in the need for separate effect estimates for distinct strata based on sex, ethnicity, language spoken at home, and school lunch source. For 10 of the 16 strata, no significant effect of play before eating was observed on lunch FV intake, while increases in intake were observed in four strata and decreases in two strata. Before rescheduling play before eating for the purpose of improving student FV intake, additional research is recommended. Copyright © 2015 Academy of Nutrition and Dietetics.

Sustainable food consumption. Product choice or curtailment?

Science.gov (United States)

Verain, Muriel C D; Dagevos, Hans; Antonides, Gerrit

2015-08-01

Food consumption is an important factor in shaping the sustainability of our food supply. The present paper empirically explores different types of sustainable food behaviors. A distinction between sustainable product choices and curtailment behavior has been investigated empirically and predictors of the two types of behavior have been identified. Respondents were classified into four segments based on their sustainable food behaviors: unsustainers, curtailers, product-oriented consumers, and sustainers. Significant differences between the segments were found with regard to food choice motives, personal and social norms, food involvement, subjective knowledge on sustainable food, ability to judge how sustainably a product has been produced and socio-demographics. It is concluded that distinguishing between behavioral strategies toward sustainable food consumption is important as consumer segments can be identified that differ both in their level of sustainable food consumption and in the type of behavior they employ.

Encapsulates for Food Bioconversions and Metabolite Production

Science.gov (United States)

Breguet, Véronique; Vojinovic, Vojislav; Marison, Ian W.

The control of production costs in the food industry must be very strict as a result of the relatively low added value of food products. Since a wide variety of enzymes and/or cells are employed in the food industry for starch processing, cheese making, food preservation, lipid hydrolysis and other applications, immobilization of the cells and/or enzymes has been recognized as an attractive approach to improving food processes while minimizing costs. This is due to the fact that biocatalyst immobilization allows for easier separation/purification of the product and reutilization of the biocatalyst. The advantages of the use of immobilized systems are many, and they have a special relevance in the area of food technology, especially because industrial processes using immobilized biosystems are usually characterized by lower capital/energy costs and better logistics. The main applications of immobilization, related to the major processes of food bioconversions and metabolite production, will be described and discussed in this chapter.

Electron irradiation of dry food products

Energy Technology Data Exchange (ETDEWEB)

Gruenewald, Th [Bundesbahn-Zentralamt, Minden (Germany, F.R.)

1983-01-01

The interest of the industrial food producer is increasing in having the irradiation facility installed in the food processing chain. The throughput of the irradiator should be high and the residence time of the product in the facility should be short. These conditions can be accomplished by electron irradiators. To clarify the irradiation conditions spices taken out of the industrial process, food grade salt, sugar, and gums as models of dry food products were irradiated. With a radiation dose of 10 kGy microbial load can be reduced on 10**4 microorganisms/g. The sensory properties of the spices were not changed in an atypical way. For food grade salt and sugar changes of colour were observed which are due to lattice defects or initiated browning. The irradiation of several gums led only in some cases to an improvement of the thickness properties in the application below 50 deg C, in most cases the thickness effect was reduced. The products were packaged before irradiation. But it would be possible also to irradiate the products without packaging moving the product through the irradiation field in a closed conveyor system.

The Chilean population has inadequate lifestyles and high prevalence of chronic diseases. To analyze eating behaviors, nutritional status and history of previous diseases, in students of higher education. Cross-sectional study in students of 54 higher education centers across the country. They answered a survey about dietary habits, physical activity, smoking, previous diseases and opinion of their nutritional condition. Weight and height were measured under standardized conditions and nutritional status classified according to body mass index. We studied 6,823 students aged 17 to 29 years. Forty seven percent did not have breakfast and 35% did not have lunch every day. A low proportion had a daily consumption of vegetables (51.2%), fruits (39.4%) and dairy products (57.5%). There was a high frequency of soft drinks, chips, cakes and sweets consumption. Seventy six percent were sedentary, 40.3% smokers and 27.4% overweight or obese. The latter had a significantly higher frequency of diabetes, hypertension and hypercholesterolemia. There was a poor agreement between actual nutritional status and self-perception, especially in males (Kappa index 0.38). Recipients of a food scholarship provided by the Ministry of Education ate lunch usually with a higher frequency (p food scholarship has some positive effects, although differences in socioeconomic levels limited comparisons.

The aim of the present study was to describe the nature and extent of food marketing on popular children's websites and food product websites in Australia. Food product websites (n 119) and popular children's websites (n 196) were selected based on website traffic data and previous research on frequently marketed food brands. Coding instruments were developed to capture food marketing techniques. All references to food on popular children's websites were also classified as either branded or non-branded and according to food categories. Websites contained a range of marketing features. On food product websites these marketing features included branded education (79.0% of websites), competitions (33.6%), promotional characters (35.3%), downloadable items (35.3%), branded games (28.6%) and designated children's sections (21.8%). Food references on popular children's websites were strongly skewed towards unhealthy foods (60.8% v. 39.2% healthy food references; Pfood references for unhealthy foods. Branded food references displayed similar marketing features to those identified on food product websites. Internet food marketing uses a range of techniques to ensure that children are immersed in brand-related information and activities for extended periods, thereby increasing brand familiarity and exposure. The relatively unregulated marketing environment and increasing use of the Internet by children point to the potential increase in food marketing via this medium. Further research is required to investigate the impact of Internet food marketing on children's food preferences and consumption, and regulatory options to protect children.

Preservation of food products by irradiation

International Nuclear Information System (INIS)

McGivney, W.T.

1988-01-01

The use of irradiation to preserve food has the potential to significantly enhance our capacity to maximize the quality and quantity of the food we consume. In a world in which distribution of food occurs across continents and in which malnourished populations are in dire need of basic food products, any safe, effective, and efficient means of preserving food is more than welcome. Irradiation, as a method for food preservation, has been studied for more than 30 years. This discussion focuses on this most recent method for the preservation of food with particular emphasis on its effects on the safety, nutritive, and aesthetic values of the food preserved by irradiation. The use of ionizing radiation as a method to preserve foods is one that has been demonstrated to be effective for a variety of food classes. Irradiation offers a means to decontaminate, disinfest, and retard the spoilage of the food supply. At the same time, it appears that the wholesomeness of these food products is maintained. Nutritive value can be sustained by use of effective doses of radiation. Concerns over the safety of irradiated food are rooted in questions regarding the potential induction of radioactivity, harmful radiolytic products, and pathogenic radiation-resistant or mutant strains of microorganisms. Research findings have allayed concerns over safety. However, more research is necessary to conclusively resolve these safety issues. Food irradiation is a promising technology that has and will contribute to our ability to feed the people of this world. This technology is but one of many available ways to preserve our greatest natural resource, the food supply. Enhancement of the ability to preserve food by irradiation will facilitate the distribution of food from fertile developed regions to the malnourished peoples of underdeveloped countries. 21 references

2015-10-01

Surveillance and control of food-borne human pathogens, such as Listeria monocytogenes, is a critical aspect of modern food safety programs at food production facilities. This study evaluated contamination patterns of Listeria species at a poultry food production facility, and evaluated the efficacy of procedures to control the contamination and transfer of the bacteria throughout the plant. The presence of Listeria species was studied along the production chain, including raw ingredients, food-contact, non-food-contact surfaces, and finished product. All isolates were sub-typed by pulsed-field gel electrophoresis (PFGE) to identify possible entry points for Listeria species into the production chain, as well as identifying possible transfer routes through the facility. The efficacy of selected in-house sanitizers against a sub-set of the isolates was evaluated. Of the 77 different PFGE-types identified, 10 were found among two or more of the five categories/areas (ingredients, food preparation, cooking and packing, bulk packing, and product), indicating potential transfer routes at the facility. One of the six sanitizers used was identified as unsuitable for control of Listeria species. Combining PFGE data, together with information on isolate location and timeframe, facilitated identification of a persistent Listeria species contamination that had colonized the facility, along with others that were transient.

2017-04-01

We examined whether people's attributions for their eating behaviour differ according to whether they believe they have eaten more, less or about the same as they normally would. Participants were served a small or large portion of pasta for lunch. Afterwards, they were asked to compare how much they ate in the study to how much they normally eat for lunch, resulting in three intake-evaluation categories: 'ate less', 'ate about the same' or 'ate more'. How much participants ate; the extent to which they attributed their food intake to an internal cue (i.e. hunger) and an external cue (i.e. the amount of food served). Participants served a large portion ate more than those served a small portion, but the magnitude of the portion-size effect did not vary across intake-evaluation categories. Furthermore, although participants in all groups indicated that their hunger influenced how much they ate, only those in the 'ate more' group indicated that the amount of food available influenced how much they ate. People appear to be willing to explain their food intake in terms of an external cue only when they believe that they have eaten more than they normally would.

To evaluate the effectiveness of the parent- and early care education (ECE) center-based Lunch is in the Bag program on communication between parent, child, and their ECE center providers around fruits, vegetables and whole grain foods (FVWG). A total of n=30 ECE center; 577 parent-child dyads participated in this group-randomized controlled trial conducted from 2011 to 2013 in Texas (n=15 ECE center, 327 dyads intervention group; n=15 ECE center, 250 dyads comparison group). Parent-child and parent-ECE center provider communication was measured using a parent-reported survey administered at baseline and end of the five-week intervention period. Multilevel linear regression analysis was used to compare the pre-to-post intervention changes in the parent-child and parent-ECE center provider communication scales. Significance was set at pparent-child and parent-ECE center provider communication scores were low. There was a significant increase post-intervention in the parent-ECE center provider communication around vegetables (Adjusted β=0.78, 95%CI: 0.13, 1.43, p=0.002), and around fruit (Adjusted β=0.62, 95%CI: 0.04, 0.20, p=0.04) among the parents in the intervention group as compared to those in the comparison group. There were no significant intervention effects on parent-child communication. Lunch is in the Bag had significant positive effects on improving communication between the parents and ECE center providers around FVWG. Copyright © 2015 Elsevier Inc. All rights reserved.

2016-02-01

Breakfast omission is positively associated with obesity and increased risk of disease. However, little is known about the acute effects of extended morning fasting upon subsequent energy intake and associated metabolic/regulatory factors in obese adults. In a randomised cross-over design, 24 obese men (n=8) and women (n=16) extended their overnight fast by omitting breakfast consumption or ingesting a typical carbohydrate-rich breakfast of 2183±393 kJ (521±94 kcal), before an ad libitum pasta lunch 3 h later. Blood samples were obtained throughout the day until 3 h post lunch and analysed for hormones implicated in appetite regulation, along with metabolic outcomes and subjective appetite measures. Lunch intake was unaffected by extended morning fasting (difference=218 kJ, 95% confidence interval -54 kJ, 490 kJ; P=0.1) resulting in lower total intake in the fasting trial (difference=-1964 kJ, 95% confidence interval -1645 kJ, -2281 kJ; Pfasting (P⩽0.06). Plasma-acylated ghrelin concentrations were also lower following the ad libitum lunch in the fasting trial (Pfasting trial (P=0.05), with plasma glucose also greater 1 h after lunch (Pfasting did not result in greater appetite ratings after lunch, with some tendency for lower appetite 3 h post lunch (P=0.09). We demonstrate for the first time that, in obese adults, extended morning fasting does not cause compensatory intake during an ad libitum lunch nor does it increase appetite during the afternoon. Morning fasting reduced satiety hormone responses to a subsequent lunch meal but counterintuitively also reduced concentrations of the appetite-stimulating hormone-acylated ghrelin during the afternoon relative to lunch consumed after breakfast.

Convenience food products. Drivers for consumption.

Brunner, Thomas A; van der Horst, Klazine; Siegrist, Michael

2010-12-01

Convenience is one of the big trends in the food business. The demand for convenience food products is steadily increasing; therefore, understanding convenience food consumption is an important issue. Despite being vital properties of convenience food, saving time and effort have not been very successful constructs for predicting convenience food consumption. To examine a wide range of possible drivers for convenience food consumption, the present study uses a convenience food frequency questionnaire that asks about consumption behavior. A paper-and-pencil questionnaire was sent out to a representative sample of people in German-speaking Switzerland and yielded N = 918 complete datasets from persons mainly responsible for buying and preparing food in the household. The various convenience food products could be categorized into four groups, which we labeled as highly processed food items, moderately processed food items, single components, and salads. Fifteen drivers were found to have a significant impact either on total convenience consumption or on one of the identified categories. Strong predictors were age, concern about naturalness, nutrition knowledge, and cooking skills. Copyright © 2010 Elsevier Ltd. All rights reserved.

Consumers’ demand for locally produced and organic foods has increased in Sweden. This paper presents the results obtained from the analysis of data acquired from 100 consumers in Sweden who participated in an online survey during March to June 2016. The objective was to identify consumers’ demand in relation to organic food and sustainable food production, and to understand how the consumers evaluate food quality and make buying decisions. Qualitative descriptions, descriptive statistics and Pearson’s Chi-square test (with alpha value of p production method is more sustainable than conventional methods. Female consumers have more positive attitudes than men towards organic food. However, age difference, household size and income level do not significantly influence the consumers’ perception of sustainable food production concepts. Regionality, sustainable methods of production and organic production are the most important parameters to characterize the food as high quality and make buying decisions. On the other hand, product uniformity, appearance, and price were found to be relatively less important parameters. Food buying decisions and food quality were found to be highly related with Pearson’s correlation coefficient of r = 0.99. PMID:29614785

At present, insects are rarely used by the European food industry, but they are a subject of growing interest as an alternative source of raw materials. The risks associated with the use of insects in the production of foods and food ingredients have not been sufficiently investigated. There is a lack of scientifically based knowledge of insect processing to ensure food safety, especially when these processes are carried out on an industrial scale.

The impact of two commercially available products, a patented herb extract Yerbe Maté, Guarana and Damiana (YGD) formulation and an inulin-based soluble fermentable fibre (SFF), alone or in combination, on appetite and food intake were studied for the first time in a double blind, placebo-controlled, cross-over design. 58 normal to slightly overweight women consumed a fixed-load breakfast followed 4h later by an ad libitum lunch. They were administered YGD (3 tablets) and SFF (5g in 100ml water), YGD and water (100ml), SFF and placebo (3 tablets) or water and placebo 15min before meals. Appetite was assessed using visual analogue scales, and energy intake was measured at lunch. Significant reductions in food intake and energy intake were observed when YGD was present (59.5g, 16.3%; 112.4kcal, 17.3%) and when SFF was present (31.9g, 9.1%; 80kcal, 11.7%) compared with conditions were products were absent. The lowest intake (gram and kcal) was in the YGD+SFF condition. Significant reductions in AUC hunger and AUC desire to eat were also observed after YGD+SFF combination. The data demonstrate that YGD produces a robust short-term effect on caloric intake, an effect augmented by SFF. Caloric compensation for SFF indicates independent effects on appetite regulation.

2016-06-01

This research examined the effects of both episodic memory and episodic future thinking (EFT) on snack food intake. In Study 1, female participants (n = 158) were asked to recall their lunch from earlier in the day, to think about the dinner they planned to have later in the day, or to think about a non-food activity before taking part in a cookie taste test. Participants who recalled their lunch or who thought about their dinner ate less than did participants who thought about non-food activities. These effects were not explained by group differences in the hedonic value of the food. Study 2 examined whether the suppression effect observed in Study 1 was driven by a general health consciousness. Female participants (n = 74) were asked to think about their past or future exercise (or a non-exercise activity), but thinking about exercise had no impact on participants' cookie consumption. Overall, both thinking about past food intake and imagining future food intake had the same suppression effect on participants' current food intake, but further research is needed to determine the underlying mechanism.

PROMOTING TRADITIONAL FOOD PRODUCTS AS HEALTHY DIET PRODUCTS

Directory of Open Access Journals (Sweden)

Mihaela Teodora TARCZA

2015-12-01

Full Text Available The aim of this paper is to propose a brief introspection in the literature review in an attempt to highlight the peculiarities of traditional foodstuffs that enable them to be promoted as the primary food for a healthy diet. The trend of healthy eating is gaining ground not only for experts and researchers, but also for consumers on a daily basis. Traditional foodstuffs are brought back into the consumers’ attention in a market full of highly-processed foodstuffs. Marketing specialists noticed the link between the two concepts and they elaborated promotional strategies for traditional foodstuffs, having the ‘healthy diet’ as insight. Throughout the paper we will present theoretical considerations such as the concept of ‘traditional food product’, ‘promotion’, and ‘healthy diet’ from a marketing perspective followed by several examples of traditional food products perceived as healthy, and lastly, we will highlight the benefits of promoting a healthy diet by consuming traditional food products.

Organic vs. Non-Organic Food Products: Credence and Price Competition

Directory of Open Access Journals (Sweden)

Yi Wang

2017-04-01

Full Text Available We analyze the organic and non-organic production choices of two firms by considering customers’ trust in organic food products. In the context of customers’ possible willingness to pay a premium price and their mistrust in organic food products, two firms first make choices on offering organic and non-organic food products. If offering organic products, a firm can further invest in the credence system to increase customers’ trust in their organic products. At the final stage, two firms determine prices. We provide serval insights. First, we characterize the market conditions in which only one firm, both firms or neither firm will choose to offer organic food products. We find that the higher the production costs or credence investment costs for organic food products are, the more likely firms are to choose to produce non-organic food products. Second, if it is expensive enough to invest in organic credence, offering organic food products may still be uncompetitive, even if organic production cost appears to have no disadvantage compared to non-organic food products. Third, we highlight how the prices of organic food products in equilibrium are affected by market parameters. We show that when only one firm offers organic food products, this firm tends to offer a relatively low price if organic credence investment is expensive. Fourth, we highlight how one firm’s credence investment decision in equilibrium can be affected by the product type choice of the other firm. We find that the investment in organic credence is lower when both firms offer organic food products compared with the case when only one firm offers organic food products.

2012-10-01

To evaluate the relationship between eating pattern (regular breakfast, lunch and dinner) and dialysis sessions, laboratory and sociodemographic characteristics in hemodialysis (HD) patients. In this cross-sectional study eating patterns, sociodemographic, laboratory and clinical parameters, depressive symptoms, quality of life, cognitive function and appetite status were assessed. Eighty-two HD patients on morning session and 60 patients on midday HD session schedules were included. Ten patients had only breakfast, 17 patients had only lunch, 26 patients had only dinner, 5 patients had breakfast and lunch but not dinner, 28 patients had breakfast and dinner but not lunch, 29 patients had lunch and dinner but not breakfast, and 19 patients had neither breakfast, nor lunch, nor dinner. In the whole group, only 8 patients reported that they had regularly eaten breakfast, lunch or dinner in all days of the week. Midday HD session, better appetite, and higher income were independently associated with having breakfast. Morning HD session, better appetite score, and higher income were independently associated with having lunch. Morning session versus midday session, nPNA, presence of hypertension, and the Mental Component Summary Score of SF-36 were independently associated with having dinner. The majority of HD patients eat one or two meals per day. Having breakfast (or lunch) is associated with midday dialysis session (or morning dialysis session, respectively), better appetite, and satisfactory income. Eating dinner was associated with morning dialysis session, hypertension, higher protein intake and higher SF-36 mental component summary score.

Scanning electron microscopy is a useful tool for understanding food contamination and directing product development of food and industrial products. The current trend in food research is to produce foods that are fast to prepare and/or ready to eat. At the same time, these processed foods must be safe, high quality and maintain all or most of the nutritional value of the original whole foods. Minimally processed foods, is the phrase used to characterize these "new" foods. New techniques are needed which take advantage of minimal processing or processing which enhances the fresh properties and characteristics of whole foods while spending less time on food preparation. The added benefit coupled to less cooking time in an individual kitchen translates to an overall energy savings and reduces the carbon emissions to the environment. Food processing changes the microstructure, and therefore, the quality, texture and flavor, of the resulting food product. Additionally, there is the need to reduce waste, transportation costs and product loss during transportation and storage. Unlike food processing, structural changes are desirable in co-products as function follows form for food packaging films and boxes as well as for building materials and other industrial products. Thus, the standard materials testing procedures are coupled with SEM to provide direction in the development of products from agricultural residues or what would otherwise be considered waste materials. The use of agricultural residues reduces waste and adds value to a currently underutilized or unutilized product. The product might be biodegradable or compostable, thus reducing landfill requirements. Manufacturing industrial and packaging products from biological materials also reduces the amount of petroleum products currently standard in the industry.

Food and value motivation: Linking consumer affinities to different types of food products.

Science.gov (United States)

de Boer, Joop; Schösler, Hanna

2016-08-01

This study uses the consumer affinity concept to examine the multiple motives that may shape consumers' relationships with food. The concept was applied in a study on four broad product types in the Netherlands, which cover a wide range of the market and may each appeal to consumers with different affinities towards foods. These product types may be denoted as 'conventional', 'efficient', 'gourmet' and 'pure'. A comparative analysis, based on Higgins' Regulatory Focus Theory, was performed to examine whether food-related value motivations could explain different consumer affinities for these product types. The affinities of consumers were measured by means of a non-verbal, visual presentation of four samples of food products in a nationwide survey (n = 742) among consumers who were all involved in food purchasing and/or cooking. The affinities found could be predicted fairly well from a number of self-descriptions relating to food and eating, which expressed different combinations of type of value motivation and involvement with food. The analysis demonstrated the contrasting role of high and low involvement as well as the potential complementarity of promotion- and prevention-focused value motivation. It is suggested that knowledge of the relationships between product types, consumer affinities and value motivation can help improve the effectiveness of interventions that seek to promote healthy and sustainable diets in developed countries.

There is emerging literature demonstrating a relationship between the timing of feeding and weight regulation in animals. However, whether the timing of food intake influences the success of a weight-loss diet in humans is unknown. To evaluate the role of food timing in weight-loss effectiveness in a sample of 420 individuals who followed a 20-week weight-loss treatment. Participants (49.5% female subjects; age (mean ± s.d.): 42 ± 11 years; BMI: 31.4 ± 5.4 kg m(-2)) were grouped in early eaters and late eaters, according to the timing of the main meal (lunch in this Mediterranean population). 51% of the subjects were early eaters and 49% were late eaters (lunch time before and after 1500 hours, respectively), energy intake and expenditure, appetite hormones, CLOCK genotype, sleep duration and chronotype were studied. Late lunch eaters lost less weight and displayed a slower weight-loss rate during the 20 weeks of treatment than early eaters (P=0.002). Surprisingly, energy intake, dietary composition, estimated energy expenditure, appetite hormones and sleep duration was similar between both groups. Nevertheless, late eaters were more evening types, had less energetic breakfasts and skipped breakfast more frequently that early eaters (all; Pmeal (P=0.015) with a higher frequency of minor allele (C) carriers among the late eaters (P=0.041). Neither sleep duration, nor CLOCK SNPs or morning/evening chronotype was independently associated with weight loss (all; P>0.05). Eating late may influence the success of weight-loss therapy. Novel therapeutic strategies should incorporate not only the caloric intake and macronutrient distribution - as is classically done - but also the timing of food.

Full Text Available Abstract Background There is little information about meal patterns and food consumption of adolescents in Palestine. The objective of this study was to describe the association between sociodemographic factors and food intake, and meal patterns among Palestinian school adolescents (12–15 year in North Gaza Strip. Methods A cross-sectional study was conducted in 2002 comprising 944 subjects in 10 schools in Gaza city, Jabalia village and Jabalia refugee camp. Self-administered questionnaires were filled in by students and parents to obtain data on frequency of meals, food intake and sociodemographic characteristics. Results High household socioeconomic status (SES was associated with the increased number of meals and the increased intakes of many nutritious foods such as; animal food items, fruits and vegetables and dairy foods. The percentage of adolescents having breakfast daily of high and low SES was 74.5% vs 55% in boys and 65.6% vs 45% in girls. The percentage of girls with refugee status who had lunch was higher (90.2% compared to the local citizen girls (83.9%, (p = 0.03. Girls were less likely to skip daily lunch (OR = 0.55, 95% CI = 0.36–0.87, p = 0.01 compared to boys. Risk of skipping lunch was three times higher among adolescents living in the village compared to Gaza well-off area (OR = 3.3, 95% CI = 1.72–6.31, p Conclusion Meal skipping is common, particularly among those of low SES and the intakes of many nutritious foods such as animal food items, fruits and vegetables and dairy foods seem to be low among adolescents of low SES. The results of this study could be used as an important base-line for future monitoring of the nutritional situation of adolescents.

To test an obesity prevention strategy derived from behavioural economics (optimal defaults plus delay), focused on changing the college dining hall service method. After a uniform pre-load, participants attended an experimental lunch in groups randomized to one of three conditions: a nutrient-dense, lower-fat/energy lunch as an optimal default (OD); a less-nutrient-dense, higher-fat/energy lunch as a suboptimal default (SD); or a free array (FA) lunch. In the OD condition, students were presented a menu depicting healthier vegetarian and omnivore foods as default, with opt-out alternatives (SD menu) available on request with a 15 min wait. In the SD condition, the same menu format was used with the positioning of food items switched. In the FA condition, all choices were presented in uniform fonts and were available immediately. Private rooms designed to provide a small version of a college dining hall, on two campuses of a Northeastern US university. First-year college students (n 129). There was a significant main effect for condition on percentage of optimal choices selected, with 94 % of food choices in the OD condition optimal, 47 % in the FA condition optimal and none in the SD condition optimal. Similarly, energy intake for those in the SD condition significantly exceeded that in the FA condition, which exceeded that in the OD condition. Presenting menu items as optimal defaults with a delay had a significant impact on choice and consumption, suggesting that further research into its long-term applicability is warranted.

Full Text Available The number of people with food hypersensitivity, namely food intolerance and food allergies, grows every year. Food intolerance is classified into following types: enzymopathy; leaky gut syndrome; psychogenic food intolerance; detoxification insufficiency and true food intolerance. Food allergens mainly are glycoproteins, haptensor polypeptides. Most cases of food allergy are IgE-mediated allergic reactions. Recent discoveries in medicine, detailing and classification of food hypersensitivity require further researches to develop modern techniques and product recipes with specified propertiesfor consumers with food hypersensitivity. Existing technologies are based on the elimination and or reduction of the content of the allergenic substance in food. The article provides an overview of causes of food intolerance and food allergy, legislative background, a list of food allergens and methods of control, market profile of hypoallergenic produce and scientific approaches to creating hypoallergenic food products based on raw materials of animal origin.

FOOD II: an interactive code for calculating concentrations of radionuclides in food products

International Nuclear Information System (INIS)

Zach, R.

1978-11-01

An interactive code, FOOD II, has been written in FORTRAN IV for the PDP 10 to allow calculation of concentrations of radionuclides in food products and internal doses to man under chronic release conditions. FOOD II uses models unchanged from a previous code, FOOD, developed at Battelle, Pacific Northwest Laboratories. The new code has different input and output features than FOOD and a number of options have been added to increase flexibility. Data files have also been updated. FOOD II takes into account contamination of vegetation by air and irrigation water containing radionuclides. Contamination can occur simultaneously by air and water. Both direct deposition of radionuclides on leaves, and their uptake from soil are possible. Also, animals may be contaminated by ingestion of vegetation and drinking water containing radionuclides. At present, FOOD II provides selection of 14 food types, 13 diets and numerous radionuclides. Provisions have been made to expand all of these categories. Six additional contaminated food products can also be entered directly into the dose model. Doses may be calculated for the total body and six internal organs. Summaries of concentrations in food products and internal doses to man can be displayed at a local terminal or at an auxiliary high-speed printer. (author)

Control of Listeria monocytogenes in food production plants

Directory of Open Access Journals (Sweden)

Dimitrijević Mirjana

2008-01-01

Full Text Available L. monocytogenes has been established in different plants for the production of food, including dairy plants, abattoirs, plants for the processing of fish, as well as those for the production of ready-to-eat (RTE food and this fact is being considered as the primary mechanism of food contamination with this bacteria. There is also the factor of numerous and diverse contaminated production equipment, because it has certain parts that are inaccessible for the necessary cleaning and disinfection. The temperature, position, as well as the material of the work surface are also linked to the contamination of plants with this bacteria. Investigations carried out so far have helped toward the better understanding of the manner and time of contamination of food items in the course of the production process, but there are still unresolved problems, including most certainly the biggest one - the adherence of bacteria and the creation of a biofilm, when the bacteria is in that condition more resistant to so-called stress factors which are usually used in the food industry for the purpose of decontamination of the surfaces with which foods come into contact. The control of L. monocytogenes in food production plants is possible primarily by using an integrated programme, compatible with the systems Hazard Analysis Critical Control Point (HACCP and Good Hygiene Practice (GHP, necessary in the production of food that is safe for the consumer. Essentially, the control measures that can contribute to reducing the incidence of findings of L.monocytogenes in the finished product, as well as the reducing of the level of contamination with this bacteria are linked, on the one hand, with hygiene procedures in the production process, and, on the other, with the applied technological procedures.

Full Text Available  The manifestation of sustainable consumption on the food market is the consumer is choice of products originating from fair trade and/or organic farming. This paper presents the level of knowledge of Fairtrade signs and organic food logo of the EU. The author describes the importance of these signs by purchasing decisions and the relationship between these factors and the declared level ofknowledge about fair trade. In November 2013 research was conducted by the Department of Marketing Strategies at the Poznań University of Economics and Polish Scientifi c Association of Marketing (PNTM. We interviewed 444 people responsible for food shopping in their households. There were structured interviews in 3 Polish cities: Poznań, Szczecin and Lublin. The results confi rm low awareness of Polish consumers in respect of Fairtrade determinations and slightly higher in the case of organic products. Information regarding the origin of the product (fair trade or organic is not important to consumers when choosing food products. With increasing knowledge on products originating from fair trade derives knowledge of both organic foods and Fairtrade signs, but not the impact of these markings on consumers’ purchasing decisions. Still, people who attach importance to this type of information are niche on the Polish market.

What is the prevalence of central kitchens that use either cook-chill or cook-freeze production systems in school foodservice settings? A descriptive study using a 5-minute telephone survey during normal working hours was conducted. Questions were designed to be easily answered with minimal need to reference other documentation. Five hundred forty school foodservice directors, managers, and supervisors working in school districts of all sizes across the United States were randomly sampled from a national commercial directory of school districts for the study. A total of 353 individuals completed the survey representing 49 of 50 states. Means, standard deviations, and percentages were evaluated for all data collected. Descriptive statistics of school district characteristics, prevalence of production systems, food transport systems, inventory methods and equipment used for reheating food are reported. The most frequently reported production system was on-site kitchens (45.3%) followed by combination production systems (40.5%) where a central kitchen delivered to a number of satellite locations in addition to schools with on-site food preparation. Central kitchens without additional on-site kitchens represented 14.2% of this study. Of those school districts using either central kitchens or combination production systems, 78% reported hot-food preparation using hot-food delivery to satellites. Cook-chill or cook-freeze production systems were reported by 22% of respondents. The high proportion of school districts that prepared and delivered foods hot to satellite sites supports continuing efforts to identify food safety practices and issues related to maintaining food quality in schools.

This year the joint FAO/IAEA Division of Atomic Energy in Food and Agriculture celebrates its 10th anniversary. The aim of these two United Nations organizations is to ensure that the technical services of both FAO and IAEA are fully co-ordinated and their programmes are designed to assist developing Member States to apply isotopes and radiation techniques to the solution of food and agricultural problems. More precisely, the medium-term objectives of the Joint Division are to exploit the potential of nuclear techniques in research and development for increasing and stabilizing agricultural production, improving food quality, protecting agricultural products from spoilage and losses and minimizing pollution of food and the agricultural environment. This account of what radioisotopes can do for man in the agricultural field is therefore to a great extent a review of the activities of the Joint Division and a prediction of its future fields of emphasis, especially in the light of the present long-range and world-wide food crisis.

Exploring water and food security: the water footprint of domestic food production in the Gaza Strip

Science.gov (United States)

Recanati, Francesca; Castelletti, Andrea; Dotelli, Giovanni; Melià, Paco

2016-04-01

Water scarcity and food security are major issues in the Gaza Strip. This area is characterized by one of the highest densities in the world and it is affected by both severe scarcity of water resources and limited trading possibilities.Given this context, the enhancement of domestic food production is considered a fundamental strategy in achieving food security in the area. For this reason, rural people play a crucial role in implementing sustainable strategies for enhancing the domestic food production while preserving water resources. In order to investigate the effectiveness of existing agricultural scenarios in achieving food security in a sustainable manner, we propose a framework to assess food production systems in terms of their contribution to the nutritional and economic conditions of rural households and their impact on water resources. In particular, the latter has been carried out through the water footprint indicator proposed by the Water Footprint Network. The case study analyzed is a sample farm located in the Gaza Strip, whose food production is based on horticulture, animal husbandry and aquaculture. The study is articulated into two main parts: first, we compare alternative scenarios of vegetal and animal food production in terms of food supply, water consumption and economic income at the household scale; then, we extend the analysis to evaluate the potential contribution of domestic food production to the food security in the whole Gaza Strip, focusing on the nutritional dimension, and providing a preliminary assessment of the environmental and economic sustainability. In particular, we evaluate water appropriation for domestic food production and compare it with the availability of water resources in the region. The outcomes highlight that the domestic food production can potentially satisfy both a basic diet and economic income for rural household, but the related appropriation of freshwater results unsustainable with respect to the fresh

2010-06-01

A method based on solid phase extraction followed by derivatization and gas chromatography-mass spectrometry analysis was validated for the determination of bisphenol A (BPA) in canned food products. This method was used to analyze 78 canned food products for BPA. Concentrations of BPA in canned food products differed considerably among food types, but all were below the specific migration limit of 0.6 mg/kg set by the European Commission Directive for BPA in food or food simulants. Canned tuna products had the highest BPA concentrations in general, with mean and maximum values of 137 and 534 ng/g, respectively. BPA concentrations in the condensed soup products were considerably higher than those in the ready-to-serve soup products, with mean and maximum values of 105 and 189 ng/g, respectively, for the condensed soups and 15 and 34 ng/g, respectively, for the ready-to-serve soups. BPA concentrations in canned vegetable products were relatively low; about 60% of the products had BPA concentrations of less than 10 ng/g. Canned tomato paste products had lower BPA concentrations than did canned pure tomato products. The mean and maximum BPA concentrations were 1.1 and 2.1 ng/g, respectively, for tomato paste products and 9.3 and 23 ng/g, respectively, for the pure tomato products.

This study is divided into three parts. The first, devoted to the use of radiations in food production, deals especially with artificial mutagenesis, selectors taking advantage of altered hereditary features in plants from irradiated seed; sterilization of animals to eliminate harmful insects (male sterilization technique); the lethal power of radiations used for the production of animal vaccins, attenuated by irradiation, against organisms which infest or degrade food products. Part two shows that radioactive atoms used as tracers to reveal migrations and chemical transformations of products such as fertilizers and pesticides can speed up all kinds of agronomical research. Their possibilities in research on animal feeding and to detect poisonous substances in foodstuffs are also mentioned. The last part is devoted to the use of nuclear techniques in irrigation and more precisely in the study of underground water flows soil moisture and lastly the future of nuclear desalination [fr

Subsistence Food Production Practices: An Approach to Food Security and Good Health.

Science.gov (United States)

Rankoana, Sejabaledi A

2017-10-05

Food security is a prerequisite for health. Availability and accessibility of food in rural areas is mainly achieved through subsistence production in which community members use local practices to produce and preserve food. Subsistence food production ensures self-sufficiency and reduction of poverty and hunger. The main emphasis with the present study is examining subsistence farming and collection of edible plant materials to fulfill dietary requirements, thereby ensuring food security and good health. Data collected from a purposive sample show that subsistence crops produced in the home-gardens and fields, and those collected from the wild, are sources of grain, vegetables and legumes. Sources of grain and legumes are produced in the home-gardens and fields, whereas vegetables sources are mostly collected in the wild and fewer in the home-gardens. These food sources have perceived health potential in child and maternal care of primary health care.

Young children should consume a variety of nutrient-dense foods to support growth, while limiting added fat and sugar. A majority of children between the ages of 3 and 5 years attend child care in the United States, which makes this environment and the child-care staff influential at meals. The aim was to determine the association between best-practice food-related behaviors and young children's tastes of fruit, vegetable, low-fat dairy, and high-fat/high-sugar foods at child care. This was a cross-sectional study. A community-based study with 201 children ages 3 to 5 years from 25 early care and education centers, including 11 tribally affiliated centers and two Head Start programs across Oklahoma. Data collection occurred from fall 2011 to spring 2014. Classroom observations used the Environmental Policy Assessment Observation tool to measure the staff behaviors and environment. Staff behavior was compared at three different levels: the composite score of staff nutrition behavior, each constituent staff behavior, and staff behaviors grouped into broader feeding behaviors. Tasted food was measured through the Dietary Observation in Child Care method. The children's meals were categorized into the following food groups: fruit, vegetable, low-fat dairy, fried vegetable, fried meat, high-fat meat, and high-fat/high-sugar food. Descriptive statistics were calculated for relevant variables. Relationships between the constituent staff behaviors and food groups that children tasted were compared using multilevel mixed-model analysis. The mean number of tasted fruit or vegetable items was higher and the mean number of tasted high-fat/high-sugar food items was lower when staff: 1) determined fullness before plate removal when less than half of food was eaten, 2) ate with the children, 3) and talked about healthy food. The utilization of the three staff behaviors and their association with higher mean tastes of nutrient-dense items and lower mean tastes of high

Neacşu, A. N.

2011-01-01

Full Text Available Food is an indispensable factor for humans and animals, because it provides the energy and substances necessary for developing the metabolic processes, which generate the body’s growth. It is the source and regulator of exchange processes between the body and the environment. Since ancient times man has received the necessary nutrients from the environment but the operation and maintenance of the body physiology constantly needs energy. In this work we focus on the chemical composition of food, and more specifically, on the amount of water contained in food products (humidity, as a factor influencing the stability and quality of food products.

2014-01-01

Nanotechnology is one of the most important tools in modern agriculture, and agri-food nanotechnology is anticipated to become a driving economic force in the near future. Agri-food themes focus on sustainability and protection of agriculturally produced foods, including crops for human consumption and animal feeding. Nanotechnology provides new agrochemical agents and new delivery mechanisms to improve crop productivity, and it promises to reduce pesticide use. Nanotechnology can boost agricultural production, and its applications include: 1) nanoformulations of agrochemicals for applying pesticides and fertilizers for crop improvement; 2) the application of nanosensors/nanobiosensors in crop protection for the identification of diseases and residues of agrochemicals; 3) nanodevices for the genetic manipulation of plants; 4) plant disease diagnostics; 5) animal health, animal breeding, poultry production; and 6) postharvest management. Precision farming techniques could be used to further improve crop yields but not damage soil and water, reduce nitrogen loss due to leaching and emissions, as well as enhance nutrients long-term incorporation by soil microorganisms. Nanotechnology uses include nanoparticle-mediated gene or DNA transfer in plants for the development of insect-resistant varieties, food processing and storage, nanofeed additives, and increased product shelf life. Nanotechnology promises to accelerate the development of biomass-to-fuels production technologies. Experts feel that the potential benefits of nanotechnology for agriculture, food, fisheries, and aquaculture need to be balanced against concerns for the soil, water, and environment and the occupational health of workers. Raising awareness of nanotechnology in the agri-food sector, including feed and food ingredients, intelligent packaging and quick-detection systems, is one of the keys to influencing consumer acceptance. On the basis of only a handful of toxicological studies, concerns have

Agrobiodiversity Genetic Variability Utilization in Organic Food Production

Directory of Open Access Journals (Sweden)

Dimitrijević Miodrag

2018-03-01

Full Text Available The food production at the global level is about to meet its border. Industrialization of agriculture correlates with an explosive enlargement of human population, during XX and at the beginning of XXI centuries. An ongoing process of environmental erosion has been speeding up during that period, not only in our physical surrounding, but also in biodiversity. A new direction in agricultural food production is in demand. Organic food production has been recognized as the way of providing safety and quality food, preserving the environment in the same time. In the other hand new land areas have to be explored for agricultural use, in order to enhance food quantity to meeting the increasing demand for food. These targets set new requirements in plant breeding. To fulfill these requirements the genetic variability harbored in genetic resources has to be preserved, examined and put to good use.

Full Text Available Author is analyzing a share of food products in the structural profile of retail trade in European Union by presenting areas of retailing in which food, beverages, and tobacco products are predominant. The main task of retailing is to overcome gaps in time and space between production and consumption, in order to meet the needs of consumers. This main task of retailing becomes more difficult considering the fact that the European Union consists of demanding consumers that expect all products, especially food, to be served to them at the most accessible places, in most suitable time, and with prices that coincide with the worth of products. In the structure of retail trade of the European Union, food products can be found in sector of non-specialised in-store retailing (hypermarkets, supermarkets, Cash&Carry stores as well as in sector of specialised in-store food retailing (butcher shops, bakeries, fish markets, etc.. Restructure of retailing, internationalization, and concentration of total retail trade network are only some of the basic trends in contemporary retail sale of food products in the European Union, that are being explored in this text.

2016-07-01

We conducted a national census survey of egg product plants (n = 57) to obtain information on the technological and food safety practices of the egg products industry and to assess changes in these practices from 2004 to 2014. The questionnaire asked about operational and sanitation practices, microbiological testing practices, food safety training for employees, other food safety issues, and plant characteristics. The findings suggest that improvements were made in the industry's use of food safety technologies and practices between 2004 and 2014. The percentage of plants using advanced pasteurization technology and an integrated, computerized processing system increased by almost 30 percentage points. Over 90% of plants voluntarily use a written hazard analysis and critical control point (HACCP) plan to address food safety for at least one production step. Further, 90% of plants have management employees who are trained in a written HACCP plan. Most plants (93%) conduct voluntary microbiological testing. The percentage of plants conducting this testing on egg products before pasteurization has increased by almost 30 percentage points since 2004. The survey findings identify strengths and weaknesses in egg product plants' food safety practices and can be used to guide regulatory policymaking and to conduct required regulatory impact analysis of potential regulations.

2017-11-02

Food product reformulation is promoted as an effective strategy to reduce population salt intake and address the associated burden of chronic disease. Salt has a number of functions in food processing, including impacting upon physical and sensory properties. Manufacturers must ensure that reformulation of foods to reduce salt does not compromise consumer acceptability. The aim of this systematic review is to determine to what extent foods can be reduced in salt without detrimental effect on consumer acceptability. Fifty studies reported on salt reduction, replacement or compensation in processed meats, breads, cheeses, soups, and miscellaneous products. For each product category, levels of salt reduction were collapsed into four groups: food products, which in turn will contribute to a healthier food supply.

Increasing either protein or fiber at mealtimes has relatively modest effects on ingestive behavior. Whether protein and fiber have additive or interactive effects on ingestive behavior is not known. Fifteen overweight adults (5 female, 10 male; BMI: 27.1 ± 0.2 kg/m²; aged 26 ± 1 year) consumed four breakfast meals in a randomized crossover manner (normal protein (12 g) + normal fiber (2 g), normal protein (12 g) + high fiber (8 g), high protein (25 g) + normal fiber (2 g), high protein (25 g) + high fiber (8 g)). The amount of protein and fiber consumed at breakfast did not influence postprandial appetite or ad libitum energy intake at lunch. In the fasting-state, visual food stimuli elicited significant responses in the bilateral insula and amygdala and left orbitofrontal cortex. Contrary to our hypotheses, postprandial right insula responses were lower after consuming normal protein vs. high protein breakfasts. Postprandial responses in other a priori brain regions were not significantly influenced by protein or fiber intake at breakfast. In conclusion, these data do not support increasing dietary protein and fiber at breakfast as effective strategies for modulating neural reward processing and acute ingestive behavior in overweight adults.

Full Text Available Abstract Background Frequency of eating breakfast, lunch and evening meal as a determinant of fruit and vegetable intake among young people is little studied. We investigated whether irregular meal consumption was associated with fruit and vegetable intake among adolescents. We used separate analyses, and special emphasis was on the potentially modifying effect of sex and age. Methods Data were from the Danish contribution to the international collaborative Health Behavior in School-Aged Children Study (HBSC in 2002. We used a questionnaire-based, cross-sectional design to study schoolchildren aged 11, 13 and 15 years (n = 3913 selected from a random sample of schools in Denmark. Fruit intake and vegetable intake were measured by a food frequency questionnaire and analyses were conducted using multivariate logistic regression. Results Overall, statistically significant associations were found between irregular breakfast, lunch and evening meal consumption and low frequency of fruit intake and vegetable intake (breakfast: fruit OR = 1.42, vegetables OR = 1.48; lunch: fruit OR = 1.68, vegetables OR = 1.83; evening meal: vegetables OR = 1.70. No association was found for irregular evening meal consumption and low frequency of fruit intake. Analyses stratified by sex showed that the associations between irregular breakfast consumption and both fruit and vegetable intake remained statistically significant only among girls. When analyses were stratified by both sex and age, different patterns appeared. Overall, skipping meals seemed to be a less serious risk factor for low frequency of fruit and vegetable intake among younger participants compared with those who were older. This was especially evident for skipping breakfast. The same tendency was also seen for skipping lunch and evening meal, although the age pattern varied between boys and girls and between fruit and vegetable intake. Conclusion Our results showed that irregular breakfast, lunch and

Probiotic food products contain a variety of different bacterial strains and may offer different health effects. The objective was to document the prevalence and dosage of probiotic strains in the Canadian food supply and to review the literature investigating these strains in order to understand what health benefits these products may offer. The Food Label Information Program was used to identify probiotic-containing products in the food supply. PubMed, Web of Science, and Embase were searched for randomized controlled trials that tested the health effects of these strains in humans. There were six probiotic strains/strain combinations identified in the food supply. Thirty-one studies investigated these strains and found that they are associated with decreased diarrhea and constipation, improved digestive symptoms, glycemic control, antioxidant status, blood lipids, oral health, and infant breastfeeding outcomes, as well as enhanced immunity and support for Helicobacter pylori eradication. There were a limited number of studies investigating these strains. Many studies were funded by the food industry and tested dosages that were up to twenty-five times the dosage found in most food products. Probiotic food products could have health benefits not currently reported on their labels. However, many dosages are too low to provide the benefits demonstrated in clinical trials. Further research is needed to enable more effective use of these functional foods.

The study illustrates how food producers' traditional make‐to‐stock (MTS approach is not well suited to meet the trends of increasing product variety, higher demand uncertainty, increasing sales of fresh food products and more demanding customers. The paper proposes a framework for differentiated PPC that combines MTS with make‐to‐order (MTO.The framework matches products with the most appropriate PPC approaches and buffering techniques depending on market and product characteristics. The core idea is to achieve more volume flexibility in the production system by exploiting favourable product and market characteristics (high demand predictability, long customer order leadtime allowances and low product perishability. A case study is used to demonstrate how the framework can enable food producers to achieve efficiency in production, inventory and PPC processes – and simultaneously be responsive to market requirements.

PICKLED PUMPKIN IS VALUABLE FOOD PRODUCT

Full Text Available One of the main directions of the food industry development is the production of functional food products. Changes in the human’s diet structure cause that none of population group does receive necessary amount of vitamins, macro and microelements in healthy routine diet. To solve this problem, food stuffs enhanced by different ingredients enable to improve the biological and food value. The pumpkin is a valuable source of such important substances as carotene and pectin. Addition of garlic and hot pepper ingredients to process of pumpkin pickling enables to enrich the products with carbohydrates, proteins, microelements, which have low or no content in the pumpkin fruit. Therefore, the study of the influence of the different quantities of garlic and hot pepper additions on chemical composition of finished product is very important. The influence of plant additions used on chemical composition of finished product had been well determined. It was shown that through increased doses of garlic and hot pepper ingredients as compared with control, the carotene and dry matter content then decreased by 1.16%-3.43% in pickled pumpkin, while the pectin content depended on added component. The highest pectin content, 0.71% was observed at addition of 10 g. garlic ingredient per 1 kg. of raw matter, that was 4.1 times higher than control. With increased addition of hot pepper ingredient the pectin accumulation was decreasing from 0.58% in control to 0.36% in variant 10g. per 1kg. of raw matter.

To review and discuss academic production (theses and dissertations) on the topic of labeling of prepackaged foods in Brazil. A search of the database maintained by the Coordination for the Development of Higher Education Professionals (CAPES), one of the two Brazilian government research funding and support agencies, was conducted on the following keywords: "rotulagem" (labeling), "rotulagem nutricional" (food labeling) and "rótulo de alimentos" (food labels). The search covered the years 1987 (earliest year available) to 2004. We identified 49 studies on this topic. Content analysis identified three major themes: the extent to which food labels meet specific legal requirements (57.2%); the degree to which consumers understand the information on labels (22.4%); and the labeling of transgenic or genetically-modified foods (20.4%). Food labeling is a frequent topic and is adequately covered by the Brazilian academic production. In most of the studies, ineffective law enforcement appears to be the main factor in the lack of compliance with and disrespect for the food labeling rules and regulations in Brazil.

Scombroid fish poisoning is a food-borne chemical intoxication caused by certain spoiled fish that contain a large amount of histamine and some biogenic diamines. It has gradually become a world-wide medical problem and probably is the most common cause of fish poisoning. As the data on the incidents of scombroid fish poisoning in Taiwan remains scarce, we report 2 incidents of scombroid fish poisoning in Northern Taiwan. We collected data of the 2 outbreaks of suspected fish poisoning which were reported to us in 1996. An epidemiological investigation was undertaken. Questionnaire interviews were given to persons who ate lunch in the same cafeteria in outbreak 2. The leftover fish were sent for species identification and toxin analysis. The first incident involving 4 women occurred in March 1996. All cases experienced flush, dizziness, blurred vision and skin rashes after eating lunch. A non-scombroid fish of Makaira with histamine levels as high as 84.13 mg/100 g flesh was implicated in this incident. In August 1996, another incident involving some cases who ate lunch at the same cafeteria were investigated. A total of 146 questionnaires were distributed with a return of 132 questionnaires (90.4%). Fifty-five employees reported positive signs or symptoms; 48 persons who ate fish and 7 women who did not eat fish were ill. Fish was the only food associated with the illness with an attack rate of 73.8% (p < 0.001). The incriminated fish was later identified as a scombroid fish of Euthynnus with a histamine content of 271.9 mg/100 g flesh in 1 leftover piece and 118.5 mg/100 g flesh in another piece. Most cases in these 2 outbreaks received treatment with antihistamines and had rapid and complete recovery. The diagnosis of scombroid fish poisoning could be misdiagnosed as food allergy or bacterial food poisoning if physicians are not aware of such poisoning. The nonspecific but characteristic symptomatology of histamine food poisoning and previous consumption of fish

Closing data gaps for LCA of food products: estimating the energy demand of food processing.

Food is one of the most energy and CO2-intensive consumer goods. While environmental data on primary agricultural products are increasingly becoming available, there are large data gaps concerning food processing. Bridging these gaps is important; for example, the food industry can use such data to optimize processes from an environmental perspective, and retailers may use this information for purchasing decisions. Producers and retailers can then market sustainable products and deliver the information demanded by governments and consumers. Finally, consumers are increasingly interested in the environmental information of foods in order to lower their consumption impacts. This study provides estimation tools for the energy demand of a representative set of food process unit operations such as dehydration, evaporation, or pasteurization. These operations are used to manufacture a variety of foods and can be combined, according to the product recipe, to quantify the heat and electricity demand during processing. In combination with inventory data on the production of the primary ingredients, this toolbox will be a basis to perform life cycle assessment studies of a large number of processed food products and to provide decision support to the stakeholders. Furthermore, a case study is performed to illustrate the application of the tools.

Food product tracing technology capabilities and interoperability.

Science.gov (United States)

Bhatt, Tejas; Zhang, Jianrong Janet

2013-12-01

Despite the best efforts of food safety and food defense professionals, contaminated food continues to enter the food supply. It is imperative that contaminated food be removed from the supply chain as quickly as possible to protect public health and stabilize markets. To solve this problem, scores of technology companies purport to have the most effective, economical product tracing system. This study sought to compare and contrast the effectiveness of these systems at analyzing product tracing information to identify the contaminated ingredient and likely source, as well as distribution of the product. It also determined if these systems can work together to better secure the food supply (their interoperability). Institute of Food Technologists (IFT) hypothesized that when technology providers are given a full set of supply-chain data, even for a multi-ingredient product, their systems will generally be able to trace a contaminated product forward and backward through the supply chain. However, when provided with only a portion of supply-chain data, even for a product with a straightforward supply chain, it was expected that interoperability of the systems will be lacking and that there will be difficulty collaborating to identify sources and/or recipients of potentially contaminated product. IFT provided supply-chain data for one complex product to 9 product tracing technology providers, and then compared and contrasted their effectiveness at analyzing product tracing information to identify the contaminated ingredient and likely source, as well as distribution of the product. A vertically integrated foodservice restaurant agreed to work with IFT to secure data from its supply chain for both a multi-ingredient and a simpler product. Potential multi-ingredient products considered included canned tuna, supreme pizza, and beef tacos. IFT ensured that all supply-chain data collected did not include any proprietary information or information that would otherwise

We propose that eating lunch late impairs the mobilization of fat from adipose tissue, particularly in carriers of PERILIPIN1 (PLIN1) variants. The aim was to test the hypothesis that PLIN1, a circadian lipid-stabilizing protein in the adipocyte, interacts with the timing of food intake to affect weight loss. A total of 1287 overweight and obese subjects [229 men and 1058 women; mean ± SD body mass index (in kg/m 2 ): 31 ± 5] who attended outpatient obesity clinics were enrolled in the ONTIME (Obesity, Nutrigenetics, Timing, Mediterranean) study. Timing of food intake was estimated with a validated questionnaire. Anthropometric variables and PLIN1 genotypes were analyzed, including 6209T>C (rs2289487), 11482G>A (rs894160), 13041A>G (rs2304795), and 14995A>T (rs1052700). The main outcomes were effectiveness of the program and weight-loss progression during 28 wk of treatment. The PLIN1 locus was associated with variability in response to a weight-loss program. Specifically, carrying the minor C allele at the PLIN1 6209T>C was associated with better weight-loss response (P = 0.035). The probability of being a better responder [percentage of weight loss ≥7.5% (median)] was 33% higher among C than among TT carriers (OR: 1.32; 95% CI: 1.05, 1.67; P = 0.017). We found an interaction of PLIN1 × food timing between the 14995A>T variant and timing of lunch eating for total weight loss (P = 0.035). Among AA carriers, eating late was associated with less weight loss (P T variant. These results contribute to our ability to implement more precise and successful obesity treatments.

Food manufacturers have made public statements and voluntary commitments, such as the Healthier Australia Commitment (HAC), to improve the nutritional quality of foods. However, limited information about the nutritional quality or healthfulness of new products makes it difficult to determine if manufacturers are doing this. The purpose of this study was to assess the healthfulness of new food products released into the Australian retail market in 2015, and whether those companies who were HAC members released healthier food options compared to non-HAC members. This cross-sectional study assessed the healthfulness of all new retail food products launched in Australia in 2015 as indexed in Mintel's Global New Products Database. Healthfulness was assessed using three classification schemes: Healthy Choices Framework Victoria, Australian Dietary Guidelines and NOVA Food Classification System. Descriptive statistics and chi-squared tests described and compared the number and proportions of new foods falling within each of the food classification schemes' categories for companies that were and were not HAC members. In 2015, 4143 new food products were launched into the Australian market. The majority of new products were classified in each schemes' least healthy category (i.e. red, discretionary and ultra-processed). Fruits and vegetables represented just 3% of new products. HAC members launched a significantly greater proportion of foods classified as red (59% vs 51% for members and non-members, respectively) discretionary (79% vs 61%), and ultra-processed (94% vs 81%), and significantly fewer were classified as green (8% vs 15%), core foods (18% vs 36%) and minimally processed (0% vs 6%) (all p food market in 2015 were classified in each of three schemes' least healthy categories. A greater proportion of new products launched by companies that publicly committed to improve the nutritional quality of their products were unhealthy, and a lower proportion were healthy

Full Text Available Abstract Consumers have rights which should not just be ignored by businesses such as the right to be a safety the right be informed the right to be heard as well as the right to a good environment and healthy. Kendari Regency as a local government has been manifested by issuing regulations and policies that support the development of local food production such as the Mayor of Kendari regulation No. 15 of 2010 and Mayor Kendari Decree No. 427 of 2012 regarding the Establishment of Community Care Local Food. It appears that the local government is trying to make this local food as an alternative food. The type of research used in this paper is a socio-legal research reviewing the local food production from the perspective of consumer protection. The outcomes of the research indicate that responsibility of food business operators in the implementation of local production is essentially an effort to assist the government in ensuring the realization of food safety system. Therefore there is a need for awareness of the laws and regulations for all parties involved towards local food production especially in Kendari Regency Southeast Sulawesi on the food production process.

By-products generated every year by the European fruit and cereal processing industry currently exceed several million tons. They are disposed of mainly through landfills and thus are largely unexploited sources of several valuable biobased compounds potentially profitable in the formulation of novel food products. The opportunity to design novel strategies to turn them into added value products and food ingredients via novel and sustainable processes is the main target of recently EC-funded FP7 project NAMASTE-EU. NAMASTE-EU aims at developing new laboratory-scale protocols and processes for the exploitation of citrus processing by-products and wheat bran surpluses via the production of ingredients useful for the formulation of new beverage and food products. Among the main results achieved in the first two years of the project, there are the development and assessment of procedures for the selection, stabilization and the physical/biological treatment of citrus and wheat processing by-products, the obtainment and recovery of some bioactive molecules and ingredients and the development of procedures for assessing the quality of the obtained ingredients and for their exploitation in the preparation of new food products.

Sharma, G.; Bhat, R.M.; Bhatt, B.C.

2010-01-01

Full text: Gamma radiation processing in the last 4-5 decades is continuously gaining importance in processing of a wide variety of products, as it can modify physical, chemical and biological properties of the materials, including food and allied products on industrial scale due its inherent qualities like ease of processing in finally packaged form, eco-friendly nature and other obvious reasons over conventional means of processing. Food and allied products are either from agricultural produce or animal origin; they get easily contaminated from soil during harvesting, handling, processing, environment conditions, storage and transport from various types of micro-organisms including pathogens. In many countries it is mandatory to bring down the population of micro-organisms to an acceptable level and complete elimination of pathogens before such products are accepted for human or animal consumption. Processing of food and allied products by radiation has its own challenges due to wider public acceptance of irradiated food, a wide range, 0.25-50kGy, of absorbed dose requirements for different category of such products and purposes, use of a variety of packaging materials in different shapes and sizes and because of its perishable nature. More than 50 countries including India in the world have accepted radiation processing of food and allied products by radiation. Dosimetry is an important aspect of radiation processing, whether it is food or allied product. Uniformity in dose delivered to these products depends on several factors such as product carrier to source frame alignment, product carrier and product/tote box design, product loading pattern, attenuation due to product thickness, product bulk density that varies from 0.1-1.0 kg/l and the plant design whether during processing product overlaps the source or otherwise. In this presentation dosimetric aspects of radiation processing of food and allied products and problems associated with dosimetry of such

Bioactive Peptides in Animal Food Products

Directory of Open Access Journals (Sweden)

Marzia Albenzio

2017-05-01

Full Text Available Proteins of animal origin represent physiologically active components in the human diet; they exert a direct action or constitute a substrate for enzymatic hydrolysis upon food processing and consumption. Bioactive peptides may descend from the hydrolysis by digestive enzymes, enzymes endogenous to raw food materials, and enzymes from microorganisms added during food processing. Milk proteins have different polymorphisms for each dairy species that influence the amount and the biochemical characteristics (e.g., amino acid chain, phosphorylation, and glycosylation of the protein. Milk from other species alternative to cow has been exploited for their role in children with cow milk allergy and in some infant pathologies, such as epilepsy, by monitoring the immune status. Different mechanisms concur for bioactive peptides generation from meat and meat products, and their functionality and application as functional ingredients have proven effects on consumer health. Animal food proteins are currently the main source of a range of biologically-active peptides which have gained special interest because they may also influence numerous physiological responses in the organism. The addition of probiotics to animal food products represent a strategy for the increase of molecules with health and functional properties.

Food and beverage price promotions may be potential targets for public health initiatives but have not been well documented. We assessed prevalence and patterns of price promotions for food and beverage products in a nationwide sample of food stores by store type, product package size, and product healthfulness. We also assessed associations of price promotions with community characteristics and product prices. In-store data collected in 2010-2012 from 8959 food stores in 468 communities spanning 46 U.S. states were used. Differences in the prevalence of price promotions were tested across stores types, product varieties, and product package sizes. Multivariable regression analyses examined associations of presence of price promotions with community racial/ethnic and socioeconomic characteristics and with product prices. The prevalence of price promotions across all 44 products sampled was, on average, 13.4% in supermarkets (ranging from 9.1% for fresh fruits and vegetables to 18.2% for sugar-sweetened beverages), 4.5% in grocery stores (ranging from 2.5% for milk to 6.6% for breads and cereals), and 2.6% in limited service stores (ranging from 1.2% for fresh fruits and vegetables to 4.1% for breads and cereals). No differences were observed by community characteristics. Less-healthy versus more-healthy product varieties and larger versus smaller product package sizes generally had a higher prevalence of price promotion, particularly in supermarkets. On average, in supermarkets, price promotions were associated with 15.2% lower prices. The observed patterns of price promotions warrant more attention in public health food environment research and intervention. Copyright © 2016 Elsevier Inc. All rights reserved.

To investigate marketing techniques used on the packaging of child-oriented products sold through supermarkets. Food and beverage products which met criteria for 'marketed to children' were recorded as child-oriented. The products were analysed for food categories, nutritional value, and type and extent of marketing techniques used. A major supermarket chain in Adelaide, South Australia. Child-oriented food and beverage products. One hundred and fifty-seven discrete products were marketed to children via product packaging; most (75·2 %) represented non-core foods, being high in fat or sugar. Many marketing techniques (more than sixteen unique marketing techniques) were used to promote child-oriented food products. Claims about health and nutrition were found on 55·5 % of non-core foods. A median of 6·43 marketing techniques per product was found. The high volume and power of marketing non-core foods to children via product packaging in supermarkets should be of concern to policy makers wanting to improve children's diet for their health and to tackle childhood obesity. Claims about health or nutrition on non-core foods deserve urgent attention owing to their potential to mislead and confuse child and adult consumers.

No free lunch

This work explores the problem of cross-lingual pairwise similarity, where the task is to extract similar pairs of documents across two different languages. Solutions to this problem are of general interest for text mining in the multilingual context and have specific applications in statistical machine translation. Our approach takes advantage of cross-language information retrieval (CLIR) techniques to project feature vectors from one language into another, and then uses locality-sensitive hashing (LSH) to extract similar pairs. We show that effective cross-lingual pairwise similarity requires working with similarity thresholds that are much lower than in typical monolingual applications, making the problem quite challenging. We present a parallel, scalable MapReduce implementation of the sort-based sliding window algorithm, which is compared to a brute-force approach on German and English Wikipedia collections. Our central finding can be summarized as "no free lunch": there is no single optimal solution. Instead, we characterize effectiveness-efficiency tradeoffs in the solution space, which can guide the developer to locate a desirable operating point based on application- and resource-specific constraints.

This study aimed to examine: (1) how the Internet has changed consumers food-buying behavior and identify its associated factors; (2) consumers' concern about food safety information of online food products. A cross-sectional study was performed from October to December 2015 in Hanoi-a Vietnamese epicenter of food service. One thousand seven hundred and thirty six (1736) customers were randomly chosen from food establishments of 176 communes. Data were collected through face-to-face interviews using structured questionnaires. The majority of participants reported using the Internet to search for food products (81.3%). The most crucial factors influencing food purchases through the Internet were convenience (69.1%) and price (59.3%). Only one-third of participants selected products based on accurate evidence about food safety certification or food origin. The majority of participants were concerned about the expiration date (51.6%), while brand (9.8%) and food licensing information (11.3%) were often neglected. People who were:(1) female, (2) highly influenced by online relationships, and (3) having difficulty in doing usual activities were more likely to look for online food products. These findings produce practical advice to consumers when purchasing their desired food products on the Internet, to online food retailers and to the Government of Vietnam to implement appropriate legislation regarding trading online food products.

Medium chain triglycerides (MCT) enhance thermogenesis and may reduce food intake relative to long chain triglycerides (LCT). The goal of this study was to establish the effects of MCT on appetite and food intake and determine whether differences were due to differences in hormone concentrations. Two randomized, crossover studies were conducted in which overweight men consumed 20 g of MCT or corn oil (LCT) at breakfast. Blood samples were obtained over 3 h. In Study 1 (n=10), an ad lib lunch was served after 3 h. In Study 2 (n=7), a preload containing 10 g of test oil was given at 3 h and lunch was served 1 h later. Linear mixed model analyses were performed to determine the effects of MCT and LCT oil on change in hormones and metabolites from fasting, adjusting for body weight. Correlations were computed between differences in hormones just before the test meals and differences in intakes after the two oils for Study 1 only. Food intake at the lunch test meal after the MCT preload (Study 2) was (mean±s.e.m.) 532±389 kcal vs 804±486 kcal after LCT (Ptriglycerides (P=0.014) and glucose (P=0.066) and a higher rise in peptide YY (PYY, P=0.017) and leptin (P=0.036) compared with LCT (combined data). Correlations between differences in hormone levels (glucagon-like peptide (GLP-1), PYY) and differences in food intake were in the opposite direction to expectations. MCT consumption reduced food intake acutely but this does not seem to be mediated by changes in GLP-1, PYY and insulin.

Allison, Abimbola; Fouladkhah, Aliyar

2018-01-01

Although vital for maintaining health when consumed in moderation, various epidemiological studies in recent years have shown a strong association between excess dietary sodium with an array of health complications. These associations are robust and clinically significant for development of hypertension and prehypertension, two of the leading causes of preventable mortality worldwide, in adults with a high-sodium diet. Data from developed nations and transition economies show worldwide sodium intake of higher than recommended amounts in various nations. While natural foods typically contain a moderate amount of sodium, manufactured food products are the main contributor to dietary sodium intake, up to 75% of sodium in diet of American adults, as an example. Lower cost in formulation, positive effects on organoleptic properties of food products, effects on food quality during shelf-life, and microbiological food safety, make sodium chloride a notable candidate and an indispensable part of formulation of various products. Although low-sodium formulation of each product possesses a unique set of challenges, review of literature shows an abundance of successful experiences for products of many categories. The current study discusses adoptable interventions for product development and reformulation of products to achieve a modest amount of final sodium content while maintaining taste, quality, shelf-stability, and microbiological food safety.

To analyse the association between food store type and the consumption of ultra-processed products in Brazil. Data from the 2008-2009 Household Budget Survey involving a probabilistic sample of 55 970 Brazilian households. Food stores were grouped into nine categories. Foods and drinks were grouped according to characteristics of food processing. The contribution of each food store type to the total energy acquired from each food processing group, and according to quintiles of consumption of ultra-processed products, was estimated. Exploratory factor analysis was conducted to identify a pattern of food store usage. Linear regression models were performed to estimate the relationship between the purchase pattern and the consumption of ultra-processed products. In line with their larger market share, supermarkets accounted for 59 % of total energy and participated most in acquisition for three food groups, with emphasis on ultra-processed products (60·4 % of energy). The participation of supermarkets in total purchase tended to increase in populations with higher consumption of ultra-processed products, while the participation of small markets and small producers tended to decrease. The purchase pattern characterized by use of traditional retail (street fairs and vendors, small markets, small farmers, butcheries) was associated with a smaller consumption of ultra-processed products. Food policies and interventions aiming to reduce the consumption of ultra-processed products should consider the influence of supermarkets on the consumption of these products. A purchase pattern based on traditional retail constitutes an important tool for promoting healthy eating in Brazil.

A small amount of food is commonly used to aid administration of medicines to children to improve palatability and/or swallowability. However the impact of this co-administered food on the absorption and subsequent pharmacokinetic profile of the drug is unknown. Existing information on food effects is limited to standard protocols used to evaluate the impact of a high fat meal in an adult population using the adult medication. In the absence of a substantial body of data, there are no specific guidelines available during development of paediatric products relating to low volumes of potentially low calorie food. This paper brings together expertise to consider how the impact of co-administered food can be risk assessed during the development of a paediatric medicine. Two case studies were used to facilitate discussions and seek out commonalities in risk assessing paediatric products; these case studies used model drugs that differed in their solubility, a poorly soluble drug that demonstrated a positive food effect in adults and a highly soluble drug where a negative food effect was observed. For poorly soluble drugs risk assessments are centred upon understanding the impact of food on the in vivo solubility of the drug which requires knowledge of the composition of the food and the volumes present within the paediatric gastrointestinal tract. Further work is required to develop age appropriate in vitro and in silico models that are representative of paediatric populations. For soluble drugs it is more important to understand the mechanisms that may lead to a food effect, this may include interactions with transporters or the impact of the food composition on gastro-intestinal transit or even altered gastric motility. In silico models have the most promise for highly soluble drug products although it is essential that these models reflect the relevant mechanisms involved in potential food effects. The development of appropriate in vitro and in silico tools is

Insect disinfestation of food and agricultural products by irradiation

International Nuclear Information System (INIS)

1991-01-01

Insect infestation is a major cause of post-harvest food loss. Use of chemical pesticides is one of the main methods of controlling storage losses caused by insects. Decades of research conducted worldwide on radiation disinfestation of food and agricultural products have shown that this method could be an alternative to the chemical treatment of foods. The advantages of irradiation processing include no undesirable residues in the foods, no resistance developed by the insects and no significant changes in the physicochemical properties or the nutritive value of the treated products. This volume contains the proceedings of the final Research Co-ordination Meeting on insect disinfestation of food and agricultural products by irradiation, held in May 1987. The individual contributions are indexed separately. Refs, figs and tabs

Application of fats in some food products

Directory of Open Access Journals (Sweden)

Raquel Vallerio Rios

2014-03-01

Full Text Available Fats and oils are very important raw materials and functional ingredients for several food products such as confectionery, bakery, ice creams, emulsions, and sauces, shortenings, margarines, and other specially tailored products. Formulated products are made with just about every part of chemistry, but they are not simple chemicals. In general, they consist of several, and often many, components. Each of these components has a purpose. Most formulated products have a micro- or nano-structure that is important for their function, but obtaining this structure is often the big challenge. Due to a rise in overweight or obesity, health concerns have increased. This fact has led to the need to the develop products with low fat content, which have become a market trend. In addition, the development of new products using fat substitutes can be a good option for companies that are always trying to reduce costs or substitute trans fat or saturated fat. However, the successful development of these products is still a challenge because fat plays multiple roles in determining the desirable physicochemical and sensory attributes, and because the consumers who want or need to replace these ingredients, seek products with similar characteristics to those of the original product. Important attributes such as smooth, creamy and rich texture; milky and creamy appearance; desirable flavor; and satiating effects are influenced by the droplets of fat, and these characteristics are paramount to the consumer and consequently crucial to the success of the product in the market. Therefore, it is important to identify commercially viable strategies that are capable of removing or reducing fat content of food products without altering their sensory and nutritional characteristics. This paper intended to provide an overview about the role of fat in different food systems such as chocolate, ice cream, bakery products like biscuits, breads, and cakes considering the major

The Green Revolution has failed to secure sustainable food production and it is hoped that biotechnology will facilitate the transition to more sustainable agriculture. Excellent progress has been made with b...

European food cultures in a macro and micro perspective: Implications for the marketing of Asian food products

DEFF Research Database (Denmark)

Askegaard, Søren; Ludvigsen, Hanne H.

This article origines as part of a Danish national food research program: Market-based Process and Product Innovation in the Food Sector (MAPP), presenting some of the results of a project concerning the cultural dimension of food consumption. Two questions of importance to Asian (with special...... attention to South East Asian) food producers and marketers are explored. First: To which extent can Asian food manufacturers consider Europe one single market? And second: Do change processes in the European food cultures faclitate adoption of more Asian food products in the coming years? Of course...... homogenoues export markets but ingeneral confirms the heterogeneity of the European fo cultures. Since these data did not contain specific information about our second question, the inclusion of Asian food products in European diets, we have investigated certain food consumption trends from a micro...

Food additives used to preserve flavor or to enhance the taste and appearance of foods are also available in oral hygiene products. The aim of this review is to provide information concerning food additives in oral hygiene products and their adverse effects. A great many of food additives in oral hygiene products are potential allergens and they may lead to allergic reactions such as urticaria, contact dermatitis, rhinitis, and angioedema. Dental practitioners, as well as health care providers, must be aware of the possibility of allergic reactions due to food additives in oral hygiene products. Proper dosage levels, delivery vehicles, frequency, potential benefits, and adverse effects of oral health products should be explained completely to the patients. There is a necessity to raise the awareness among dental professionals on this subject and to develop a data gathering system for possible adverse reactions.

Extrusion technology has rapidly transformed the food industry with its numerous advantages over other processing methods. It offers a platform for processing different products from various food groups by modifying minor or major ingredients and processing conditions. Although cereals occupy a large portion of the extruded foods market, several other types of raw materials have been used. Extrusion processing of various food groups, including cereals and pseudo cereals, roots and tubers, pulses and oilseeds, fruits and vegetables, and animal products, as well as structural and nutritional changes in these food matrices are reviewed. Value addition by extrusion to food processing wastes and by-products from fruits and vegetables, dairy, meat and seafood, cereals and residues from starch, syrup and alcohol production, and oilseed processing are also discussed. Extrusion presents an economical technology for incorporating food processing residues and by-products back into the food stream. In contemporary scenarios, rising demand for extruded products with functional ingredients, attributed to evolving lifestyles and preferences, have led to innovations in the form, texture, color and content of extruded products. Information presented in this review would be of importance to processors and researchers as they seek to enhance nutritional quality and delivery of extruded products.

2016-01-01

Full Text Available Agricultural and food products are a significant segment of the total foreign trade of Serbia, which is characterized by a relatively high import dependency, modest export and constantly present deficit. In such conditions, agrarian sector serves as a stabilizer, and its importance is reflected in the permanently positive balance, increased participation, particularly in total exports, and balancing the trade balance of the country. The aim of the paper is to analyze the basic characteristics of foreign trade of agricultural and food products of Serbia in the period 2005-2015. The tendencies in export, import, and the level of coverage of import by export of agro-food (or agrarian products are analysed. The participation of these products in the total foreign trade of Serbia is also considered, followed by the comparison of this indicator with the neighbouring countries. In the next part of the paper, the structure of Serbian export and import of agricultural and food products (by product groups is analysed. Special attention is given to the territorial orientation of export and import of agrarian products by the most important trade partners. In order to conduct more comprehensive analysis of comparative advantages, or competitiveness of certain groups of agro-food products of Serbia in the exchange with the world, indicator of Revealed Comparative Advantage (RCA is calculated. The analysis of qualitative competitiveness is derived using the indicator - unit value of export and import. The analysis points to the dynamic growth in the value of Serbian export and import of agro-food products, with the constant surplus of trade balance in the observed period. These products are significantly represented in the structure of the total foreign trade of the country, particularly in export (with about 20%. RCA indicators show that Serbia has a comparative advantage in trade of agro-food products to the world in primary products and products of lower

Full Text Available Very small but cumulated decreases in food intake may be sufficient to erase obesity over a period of years. We examine the effect of slight changes in the accessibility of different foods in a pay-by-weight-of-food salad bar in a cafeteria serving adults for the lunch period. Making a food slightly more difficult to reach (by varying its proximity by about 10 inches or changing the serving utensil (spoon or tongs modestly but reliably reduces intake, in the range of 8-16%. Given this effect, it is possible that making calorie-dense foods less accessible and low-calorie foods more accessible over an extended period of time would result in significant weight loss.

This study examined inulin content in 266 samples. They were 126 dried, 105 liquid and 27 semi-solid of twelve commercial inulin fortified food products and 8 samples of natural dried sunchoke. For dried food products, inulin content ranged from 3.0 ±0.8g/100g fresh weight (FW) in milk powder to 83.7± 17.8g/100g FW in inulin powder. The levels in a descending order are the powder of inulin, weight control diet, coffee mixed, instant beverage, supplemented food products for pregnant and milk. For liquid fortified foods, inulin at the level of 0.3± 0.1g/100mL FW was found in UHT milk, and up to 13.5± 4.1g/100mL FW in weight control diet beverage. The level of 2.0-2.3g/100g FW of inulin was found in beverage with different flavours, soybean milk and fruit juice. For semi-solid food, cream yoghurt, inulin at 3.9± 1.1g/100g FW was found. A serving of most products contributes inulin at 11-33% of the recommended daily intake of dietary fibre. Copyright © 2014 Elsevier Ltd. All rights reserved.

Food insecurity is simply defined as uncertain access to adequate food. Nearly 50 million Americans, 16 million of whom are children, are food insecure. Mississippi has 21% food insecure citizens, and has the most food insecure county in the nation. Our state's school system's National Breakfast and Lunch Programs help combat food insecurity, but a gap still exists. This gap widens during the summer. In this paper, we describe the Mississippi Summer Food Service Program. While the program has had success in our state, it still faces challenges. Organized action by physicians in Mississippi and the Mississippi State Medical Association could significantly increase participation in these programs that are vital to our state.

Full Text Available In Brazil, there is resistance of the population to the use of stalks, leaves, peels and seeds of vegetables and fruits, leading to trash important parts of the food in good physiological conditions and with the presence of potential nutrients. In this research, a morning product was elaborated using green and dry coconut residue, jerimum and melon seed, crystallized sicilian lemon peel, cashew nut, common rapadura sweet and ginger. The bacteriological tests proved the hygienic-sanitary quality of the product, therefore suitable for consumption, that is, according to RDC 12/2001. It was also observed that the dehydration of all the residues reached the legal levels and accepted by ANVISA that limits in 25% the water content in the dehydrated foods. As for the centesimal composition, it was observed that the elaborated product with residues and other ingredients had a good content of macro nutrients. A use of the type of waste as a new food proposal constitutes an alternative to avoid and reduce: the serious environmental problem caused by the large residual volume generated, and the inadequate places in which they are stored or deposited, aggravating the scenario of food-borne pollutants.

Protection against radioactive contamination of food and agricultural products

International Nuclear Information System (INIS)

Szabo, A.; Kovacs, Z.

Due to contaminating effects from nuclear explosions and nuclear power plants, the systematic investigation of environmental radioactive contamination is absolutely necessary. In order to reduce the artificial radiation dose to which the human body is exposed, isotope content of foods and agricultural products should be known. The authors evaluate the decontamination possibilities of food produced from vegetable and animal products, starting from the contamination of some products. For vegetable product decontamination the use of suitable fertilizers, thorough scrubbing in excess water and, for cereals, milling is proposed. As the most effective preventive measure of radiation contamination of food products of animal origin, appropriate packing is proposed. The storage and preservation problems are emphasized for short half-life radiation contamination. (P.J.)

The measurement of the stable isotope contents provides useful information for the detection of many frauds in food products. Nuclear magnetic resonance (NMR) and isotopic ratio mass spectroscopy (IRMS) are the two main analytical techniques used for the determination of stable isotope contents in food products. These analytical techniques have been considerably improved in the last years offering wider possibilities of applications for food analysis. A review of the applications for the control of food products and beverages is presented. The need for new reference materials is discussed. (author)

We compare the Children's Food and Beverage Advertising Initiative's (CFBAI's) April 2014 list of food and beverage products approved to be advertised on children's television programs with the federal Interagency Working Group's nutrition recommendations for such advertised products. Products were assessed by using the nutrients to limit (saturated fat, trans fat, sugar, and sodium) component of the Interagency Working Group's recommendations. Fifty-three percent of the listed products did not meet the nutrition recommendations and, therefore, were ineligible to be advertised. We recommend continued monitoring of food and beverage products marketed to children.

It was mainly the advances in understanding the relationship between nutrition and health that resulted in the development of the concept of functional foods, which means a practical and new approach to achieve optimal health status by promoting the state of well-being and possibly reducing the risk of disease. Functional foods are found virtually in all food categories, however products are not homogeneously scattered over all segments of the growing market. The development and commerce of these products is rather complex, expensive and risky, as special requirements should be answered. Besides potential technological obstacles, legislative aspects, as well as consumer demands need to be taken into consideration when developing functional food. In particular, consumer acceptance has been recognized as a key factor to successfully negotiate market opportunities. This paper offers a brief overview of the current functional food market situation in USA, Japan and some European countries completed with some comments on functional food future potential. It explores the main challenges of such product development focusing on the different factors determining the acceptance of functional food. Furthermore it discusses some prominent types of these food products currently on the market.

Farm Organization, Ownership and Food Productivity in Nigeria

Full Text Available African food production is in crisis. Today, despite Africa’s vast physical and climatic potentials to produce food, most African States depend on food importation. Africa’s capacity to deal with its food battles is severely constrained by its political instability, its early stage of scientific and institutional development, and a rapidly changing and complex global environment. In Nigeria and in most developing economies, there is a fundamental lack of political commitment to come grips with poverty, malnutrition and access to food. Because of these barriers, traditional economics is a rather limited tool to understand food production and other related variables. Poverty, hunger, malnutrition, famine and starvation in developing economies are just as much a function of political, macroeconomic, and institutional barriers as lack of technology. Illustrations from the agrarian chaos in Sudan, Ethiopia, Somalia, Chad and others are too numerous to conclude otherwise. The aim of this paper is to determine and analyze economics incentives and strategies, which could stimulate commercial agriculture in Nigeria. The analysis is based on the premise that the form of production organization in Nigerian agriculture is the major constraint to commercialization. The paper concludes that output price subsidy is the over-riding factor in the commercialization of agriculture in Nigeria.
