School meals: types of foods offered to and consumed by children at lunch and breakfast.
ABSTRACT Children's food intakes do not meet dietary recommendations. Meals offered through the National School Lunch Program and School Breakfast Program make substantial contributions to school-aged children's diets.
This article describes foods offered in school meals and consumed by children at lunch and breakfast, and differences in foods consumed by children who did and did not participate in the school meal programs.
Data were collected as part of the third School Nutrition Dietary Assessment Study, a cross-sectional, nationally representative study conducted in 2005. School menu surveys were used to identify the foods offered in school meals, and 24-hour dietary recalls were used to assess the foods children consumed.
Foodservice managers in 398 public schools and 2,314 children (grades 1 to 12) from 287 of these schools participated in the study.
Descriptive tabulations report percentages of daily menus that offered and percentages of children that consumed specific food groups and foods at lunch and breakfast. Two-tailed t tests were used to assess differences between school meal program participants and nonparticipants.
Most school menus offered nonfat or 1% milk, fruit or 100% juice, and vegetables daily. Starchy vegetables were more common than dark green/orange vegetables or legumes. School lunch participants were significantly more likely than nonparticipants to consume milk, fruit, and vegetables, and significantly less likely to consume desserts, snack items, and beverages other than milk or 100% juice. At breakfast, participants were significantly more likely than nonparticipants to consume milk and fruit (mainly 100% juice), and significantly less likely to consume beverages other than milk or 100% juice.
Consumption of school meals is positively related to children's intakes of key food groups at lunch and breakfast. Offering more fresh fruit, whole grains, and a greater variety of vegetables could lead to additional health benefits.

ABSTRACT: The aim of this study was to validate the visual estimation method for aggregated plate waste of main dish at Portuguese primary school canteens. For this purpose plate waste at school lunch was measured for 505 individual servings, using weighing individual servings and plate waste and visual estimation method by a 6-point scale, as developed by Comstock et al. (1981). A high variability of initial serving weights was found with serving sizes ranging from 88.9 to 283.3g and with a coefficient of variation ranging from 5.5% to 24.7%. Mean plate waste was 27.5% according to the weighing method. There was a significant bias in the conversion of the visual waste estimations to actual waste, being overestimated by an average of 8.0g (ranging from -12.9g to 41.4g). According to Bland and Altman plot, the mean difference between methods was of 8.0g and the amplitude interval was 102.6g. The study showed that the visual estimation method is not as accurate as the weighing method in assessing nonselective aggregated plate waste at primary school canteens. Our findings are thus very important on considering plate waste assessment, since the wide variation on initial servings introduces a relevant bias when considering standard portions or a random sample of initial servings. Although, greater convenience, time-saving and the possibility to monitor plate waste of large groups, make the visual estimation method an important method to assess plate waste at school canteens, these results highlighted the need of portions standardization and control of initial servings to allow for its use.Waste Management 08/2014; 34(8):1362-1368. · 3.16 Impact Factor

ABSTRACT: Food from lunch packs (LP) or food available inside and outside of school can play an important role in the development of obesity. The purpose of this study was to evaluate the LP of elementary school (ES) and preschool children (PS) in Tijuana, and the foods available to them inside and outside of school. Eight public schools participated in the study. A random sample of all the groups from a school district was conducted. A questionnaire was administered to children in first through sixth grade (ES) and to the parents of PS. LP and food available inside and outside of the school were classified as healthy, unhealthy, and adequate according to the guidelines set forth by the Secretariat of Health. A total of 2,716 questionnaires were administered and the content of 648 LP was assessed. It was observed that 99 % of PS had LP prepared at home, a higher percentage than ES. None of the LP of the ES was classified as healthy, and 1 % was classified as adequate. Among PS, 21 % of the LP were classified as healthy and 6 % as adequate. More than half of the children recognized the brand name of foods high in fat, salt, and added sugar available inside and outside of school grounds. Most of the LP of ES and PS and the foods available inside and outside of school were unhealthy and inadequate. A strategy to prevent the availability of unhealthy and inadequate food in LP and foods available inside and outside schools is recommended.Journal of Community Health 11/2013; 38(6):1166-1174. · 1.28 Impact Factor

ABSTRACT: Objective: School Nutrition Programs (SNPs) may have positive effects on children's food choices through high nutritional quality meals. This cross-sectional & descriptive study was conducted to determine nutritional quality of school lunch and to compare lunch consumption of students who participated in SNP and who did not, at the first governmental school serving school lunch in Kayseri, Turkey. Methods: One hundred and sixteen students aged 9-14 years were divided into two groups after being matched according to gender, age, grade; 58 participants (school lunch group; SL-G) and 58 nonparticipants (school canteen group; SC-G) were recruited. Energy-nutrient content of 5-day school lunch was determined by recipes. Socio-demographic data and lunch consumption on 5 consecutive weekdays with weighed left overs were obtained. Lunch energy-nutrient intakes and anthropometric measurements were compared. Results: School lunch was adequate for vitamins (E & C), fibre, iron, inadequate for energy, carbohydrate, folate, calcium. Contribution of fat (36.6±6.8%) and saturated fat (12.2±3.5%) to energy and sodium content was high (1001 mg) in school lunch. SL-G consumed significantly higher protein, vitamin C, thiamine, vitamin B6, potassium, magnesium, iron, zinc (p<0.001 for each) than SC-G. Energy (p<0.001), carbohydrate (p<0.001), fat (p<0.05), vitamin E (p<0.001) intakes of SC-G were significantly higher than SL-G. Body weights, height, body mass index of groups were similar. Conclusions: Foodservice at school should be revised with collaboration of school management, catering firm, dietetic professionals. Policy should focus on reducing fat, saturated fat, sodium content and meeting energy-nutrient requirements of school aged children.Pakistan Journal of Medical Sciences Online 05/2014; 30(3):549-53. · 0.10 Impact Factor
