Effects of the active botanical blend "WKUP GT" on attention and cognitive functions after lunch in healthy volunteers.

OBJECTIVES: "WKUP GT", a low caffeine beverage consisting of carob, Guarana, Green Tea and Elderberry extracts was studied on attention and cognitive functions post-lunch in a pilot randomized double blind placebo controlled trial. METHODS: Thirty healthy volunteers were included in a crossover design trial, presenting five beverages randomly assigned to the following groups: placebo, "WKUP GT" (single, double or triple doses), or "caffeine" as an active control. Hemodynamic measurements were assessed as safety outcomes. The Cambridge Neuropsychological Test Automated Battery (CANTAB), was used to evaluate the patients when beverages were consumed 30 and 120 min after lunch (respectively Delta30 and Delta120 considering baseline). RESULTS: Drinking "caffeine" or "WKUP GT" after lunch, showed significant improvement (p < 0.05) in rapid visual information processing compared to placebo (Delta120 of "caffeine", "WKUP" single and double). In addition, improvement in Multitasking Test (Delta30 for "WKUP" double, and Delta120 for "caffeine" and "WKUP" triple compared to placebo) was observed. "WKUP" triple also showed significant improvement for "memory" when compared to placebo (Delta120). Compared to "caffeine", WKUP GT did not increase systolic blood pressure. CONCLUSION: "WKUP GT" showed improvements for attention, memory, psychomotor and executive function tasks after lunch without increase in pulse rate.

Associations of regular consumption of breakfast, lunch and dinner with Body Mass Index during adolescence: longitudinal findings by weight status among the Eating and Activity over Time 2010-2018 cohort.

OBJECTIVE: To examine how the associations between meal consumption and BMI over 8 years differ by weight status in a sample of adolescents. DESIGN: Longitudinal, population-based study. Breakfast, lunch and dinner consumption and BMI were self-reported. Linear regressions were used to examine how the associations between meal consumption and BMI differed by weight status. SETTING: Adolescents in the Minneapolis/St. Paul metropolitan area. PARTICIPANTS: Adolescents (n 1,471) were surveyed as part of the EAT 2010-2018 in 2009-2010 (Mage = 14·3 years) and 2017-2018 (Mage = 22·0 years). RESULTS: The prevalence of regular breakfast, lunch and dinner consumption (≥ 5 times/week) ranged from 45 to 65 %, 75 to 89 % and 76 to 94 %, respectively, depending on weight status category. Among adolescents with a sex- and age-specific BMI < 15th percentile, regular consumptions of breakfast, lunch and dinner during adolescence were positively associated with BMI in emerging adulthood compared with irregular consumption of breakfast, lunch and dinner (<5 times/week) after adjustment for socio-demographic characteristics (ß = 5·43, ß = 5·39 and ß = 6·46, respectively; all P-values <0·01). Among adolescents in the BMI 15-85th and 85-95th percentiles, regular consumptions of breakfast, lunch and dinner were positively associated with BMI but to a lesser extent (P-values <0·01). For participants with a BMI ≥ 95th percentile, regular consumptions of breakfast, lunch and dinner were positively associated with BMI, but the associations were not statistically significant (P-values > 0·05). CONCLUSIONS: The relationship between meal consumption during adolescence and BMI in emerging adulthood differs by adolescent weight status. Future studies should investigate underlying factors related to meal consumption routines and BMI.

Subject-specific timing adaption in time-encoded arterial spin labeling imaging.

OBJECTIVES: One challenge in arterial spin labeling (ASL) is the high variability of arterial transit times (ATT), which causes associated arterial transit delay (ATD) artifacts. In patients with pathological changes, these artifacts occur when post-labeling delay (PLD) and bolus durations are not optimally matched to the subject, resulting in difficult quantification of cerebral blood flow (CBF) and ATT. This is also true for the free lunch approach in Hadamard-encoded pseudocontinuous ASL (H-pCASL). MATERIAL AND METHODS: Five healthy volunteers were scanned with a 3 T MR-system. pCASL-subbolus timing was adjusted individually by the developed adaptive Walsh-ordered pCASL sequence and an automatic feedback algorithm. The quantification results for CBF and ATT and the respective standard deviations were compared with results obtained using recommended timings and intentionally suboptimal timings. RESULTS: The algorithm individually adjusted the pCASL-subbolus PLD for each subject within the range of recommended timing for healthy subjects, with a mean intra-subject adjustment deviation of 47.15 ms for single-shot and 44.5 ms for segmented acquisition in three repetitions. DISCUSSION: A first positive assessment of the results was performed on healthy volunteers. The extent to which the results can be transferred to patients and are of benefit must be investigated in follow-up studies.

Sex-dependent impact of a short rest after lunch on hemodynamics as assessed by Doppler sonography.

PURPOSE: Taking a short rest after lunch suppresses increases in blood flow to the digestive organs and maintains blood flow to the brain in the afternoon, possibly providing beneficial effects in preventing post-prandial drowsiness. The present study investigated sex-dependent influences on changes in hemodynamics produced by taking a short rest after lunch. METHODS: Subjects comprised 20 healthy young adults (10 men, 10 women; mean age 21 ± 1 years). Doppler sonography was performed to measure blood flow in the superior mesenteric artery (SMA) and common carotid artery (CCA) before and after lunch every hour on each day, with and without a 15-min rest with eyes closed after lunch. Blood pressure and heart rate (HR) were also measured. RESULTS: For both men and women, peak systolic velocity (PSV) in the SMA was suppressed by taking a rest. PSV in the CCA in men was increased at 0.5 h after lunch in the resting condition but was decreased in the non-resting condition (median 109%, interquartile range [IQR] 102-120% vs. median 98%, IQR 90-107%; P = 0.037). No such differences were observed in women. Although post-prandial increases in HR were observed in women, a similar increase was only found for men in the resting condition. CONCLUSION: An increase in CCA blood flow was observed only in men. The present study suggests that a short rest after lunch could better promote the maintenance of blood flow to the brain in men than in women.

Self-perceived food literacy in relation to the quality of overall diet and main meals: A cross-sectional study in Japanese adults.

This cross-sectional study aimed to assess the relationship between self-perceived food literacy (SPFL) and quality of overall diet and main meals in Japanese adults. In total, 5998 adults aged 20-79 years were included in this analysis. The SPFL was assessed using the Japanese version of the 29-item Dutch SPFL scale (score range 1-5). Using validated dietary information, the Healthy Eating Index-2015 (HEI-2015) was calculated (score range 0-100). The mean SPFL was 3.18; the internal consistency of the overall scale was considered good (Cronbach's alpha: 0.80). The mean HEI-2015 for overall diet was 50.4. The SPFL was significantly and positively associated with the HEI-2015. Using multiple linear regression, one point increase of SPFL corresponded to an increase in HEI-2015 by a point of 4.8 for overall diet, 6.2 for breakfast, 4.6 for lunch, and 3.6 for dinner (all P < 0.0001). Six of the eight domains of SPFL (i.e., food preparation skills, resilience and resistance, healthy snack styles, examining food labels, healthy budgeting, and healthy food stockpiling) were significantly associated with the HEI-2015 for overall diet. When the HEI-2015 for each meal was examined, the domains showing significant associations with all three meals included food preparation skills, healthy snack styles, and healthy budgeting. The healthy food stockpiling was associated with the HEI-2015 for breakfast and lunch, but not dinner. The social and conscious eating and daily food planning were associated with the breakfast HEI-2015 only, with the resilience and resistance associated with the dinner HEI-2015 only. In conclusion, the SPFL was cross-sectionally associated with the quality of overall diet and main meals in Japanese adults. Further observation and intervention studies are needed to confirm the associations observed here.

Greenhouse gas emissions of school lunches provided for children attending school nurseries: A cross-sectional study.

BACKGROUND: Schools and early years settings provide an opportunity to promote healthy and sustainable food, but standards and guidance in England focus predominantly on nutritional quality. The present study estimated greenhouse gas emissions (GHGE) of school lunches provided for children attending school nurseries, including comparison between meal options. METHODS: Menus, recipes and portion weights for lunches provided for 3-4-year-old children attending nine school nurseries were collected daily for one week. GHGE for each food and recipe were calculated using Foodprint functionality of Nutritics software. GHGE were calculated for each menu option (main, vegetarian, jacket potato and sandwich) provided in each school, and for meals with and without meat/fish. RESULTS: In total, 161 lunches including 273 foods were analysed. Median GHGE across all meals was 0.53 kgCO2e (i.e. kilograms of carbon dioxide equivalent) per portion, with significantly higher GHGE associated with main meals (0.71 kgCO2e per portion) compared to all other meal types (0.43-0.50 kgCO2e per portion; p < 0.001) which remained after adjustment for meal size and energy density. Red meat-based meals were highest in GHGE (median 0.98 kgCO2e per portion and 0.34 kgCO2e per 100 g) and meals containing any meat/fish were significantly higher in GHGE (median 0.58 kgCO2e per portion) than vegetarian meals (median 0.49 kgCO2e per portion) (p = 0.014). Meals with higher adherence to the nutrient framework underpinning the early years guidelines had significantly higher GHGE than meals with lower adherence (p < 0.001). CONCLUSIONS: The results were comparable to previous estimates of school lunch GHGE and highlight variation by meal option. Consideration of GHGE alongside the nutritional quality of lunches by caterers could support provision of healthy and sustainable lunches.

Long-Term Effectiveness of a Multi-Strategy Choice Architecture Intervention in Increasing Healthy Food Choices of High-School Students From Online Canteens (Click & Crunch High Schools): Cluster Randomized Controlled Trial.

BACKGROUND: School canteens are a recommended setting to influence adolescent nutrition due to their scope to improve student food choices. Online lunch ordering systems ("online canteens") are increasingly used and represent attractive infrastructure to implement choice architecture interventions that nudge users toward healthier food choices. A recent cluster randomized controlled trial demonstrated the short-term effectiveness (2-month follow-up) of a choice architecture intervention to increase the healthiness of foods purchased by high school students from online canteens. However, there is little evidence regarding the long-term effectiveness of choice architecture interventions targeting adolescent food purchases, particularly those delivered online. OBJECTIVE: This study aimed to determine the long-term effectiveness of a multi-strategy choice architecture intervention embedded within online canteen infrastructure in high schools at a 15-month follow-up. METHODS: A cluster randomized controlled trial was undertaken with 1331 students (from 9 high schools) in New South Wales, Australia. Schools were randomized to receive the automated choice architecture intervention (including menu labeling, positioning, feedback, and prompting strategies) or the control (standard online ordering). The foods purchased were classified according to the New South Wales Healthy Canteen strategy as either "everyday," "occasional," or "should not be sold." Primary outcomes were the average proportion of "everyday," "occasional," and "should not be sold" items purchased per student. Secondary outcomes were the mean energy, saturated fat, sugar, and sodium content of purchases. Outcomes were assessed using routine data collected by the online canteen. RESULTS: From baseline to 15-month follow-up, on average, students in the intervention group ordered significantly more "everyday" items (+11.5%, 95% CI 7.3% to 15.6%; P<.001), and significantly fewer "occasional" (-5.4%, 95% CI -9.4% to -1.5%; P=.007) and "should not be sold" items (-6%, 95% CI -9.1% to -2.9%; P<.001), relative to controls. There were no between-group differences over time in the mean energy, saturated fat, sugar, or sodium content of lunch orders. CONCLUSIONS: Given their longer-term effectiveness, choice architecture interventions delivered via online canteens may represent a promising option for policy makers to support healthy eating among high school students.

Unpacking the cost of the lunchbox for Australian families: a secondary analysis.

Ninety per cent of Australian school children bring a home-packed lunch to school, with 44% of the food consumed during school hours being unhealthy. Among other factors, cost is a key consideration for food provision; however, the costs to Australian families are not well understood. Therefore, we aimed to determine what families are currently paying for school lunchboxes in Australian primary schools and to examine associations between food costs and socio-demographic factors with dietary quality. An audit of local retail outlets was used to determine the food costs of lunchbox contents. Costs (AUD) were adjusted for inflation as of early 2023. The lunchboxes of 1026 children aged 4-12 years at 12 Catholic primary schools in New South Wales, Australia, were assessed at the start of the day, using photography assessment methods and a validated School Food Checklist. The mean cost of lunchbox contents was $4.48 AUD (SD 1.53), containing a mean energy of 2699 kJ (SD 859), with 37.3% (SD 23.9) of energy sourced from unhealthy foods. Multiple linear regression analyses found that the strongest predictors of higher lunchbox cost (P < 0.05) were a higher proportion of energy from unhealthy foods (B = 0.016) and lower Socio-Economic Indexes for Areas (B = -0.178), when controlling for child socio-demographics. The results indicated that lunchbox food costs to Australian families are comparable to alternative school food service models in Australia and internationally. Results demonstrate the cost of food is not the only barrier to providing a healthy school lunchbox. Demonstrating a need for cost-considerate systematic interventions addressing food provision challenges and socio-economic disparities faced by families.

Parents face several barriers in providing a healthy school lunch for their primary school children: A survey of Victorian (Australian) parents.

ISSUE ADDRESSED: This paper aims to explore Victoria parents' perceptions of their current practices and barriers in providing school lunches for their primary school children. METHODS: Respondents were asked via an online survey about their lunch provision practices, perceptions of the healthiness of school lunches, and barriers to providing healthy school lunches. Data were analysed using different statistical techniques: Chi-square test, Spearman correlation analysis, Mann-Whitney U test, and Kruskal-Wallis test. RESULTS: In total, 359 respondents completed the survey. Most respondents (84%) reported their child takes a home-packed lunch to school every day. Most respondents provided fruits (94%), vegetables (57%), and sandwiches (54%) every day for school lunches, whilst other core food items such as milk, meats, and legumes were provided less frequently. A substantial proportion of respondents provided some discretionary food items frequently (e.g., the proportion of respondents providing selected discretionary food items daily or 3-4 times/week: salty crackers-50%, sweet cookies/biscuits-40%, chips-20%). Respondents strongly agreed or agreed with several barriers; examples include not packing certain foods due to food spoilage concerns (50%) (school-related), the allocated time at their child's school is not enough to eat and enjoy school lunch (48%) (school-related), need more meal ideas (61%) (parent-related), healthy foods take more time to prepare (51%) (parent-related), and children request easy-to-eat food for school lunches (50%) (child-related). Core food score (an indicator of frequency of preparing/packing core food) was negatively correlated with parent-related and child-related barrier scores, whilst discretionary food score (an indicator of frequency of preparing/packing discretionary food) was positively correlated with these barrier scores. CONCLUSIONS: Overall, home-packed lunches remain the main option in primary schools in Victoria, and parents face several challenges in providing healthy lunches for their primary school children. SO WHAT?: The findings suggest the need for strategies from school leaders, education authorities, and policymakers to improve the quality of lunch content and address the barriers faced by parents.

[CURRENT STATUS OF SCHOOL LUNCHES RELATED TO FOOD ALLERGY AND UNMET NEEDS OF TEACHERS IN MIYAGI PREFECTURE].

BACKGROUND: The number of students with food allergies is on the increase, while the problems and burdens of school teachers and staff are not yet clear. Our study was designed to identify the unmet needs of school teachers and staff dealing with food allergy in school lunches. METHODS: A written questionnaire was sent by mail to 600 elementary and junior high schools in Miyagi Prefecture. RESULTS: Responses were received from 169 schools. The prevalence of food allergy was 5.6% and the EpiPen possession rate was 0.36%. The most common problems perceived by teachers and staff were the "increase in the number of students with food allergies" and the "diversification of causative foods". Other problems included "uncertainty of foods to be removed" and "insufficient collaboration among teachers, guardians, and doctors," which could be improved by the medical providers. In the free descriptions, many respondents complained of an excessive workload and the mental burden of never making a mistake or missing anything. CONCLUSION: Our survey revealed that while there is a public demand for safe school lunches, the teachers and staff dealing with this demand are under considerable strain. It is necessary to consider reducing the burden, and a sustainable system needs to be established.

[TWO SCHOOL-AGED CASES OF FRUIT GIBBERELLIN-REGULATED PROTEIN ALLERGY WHICH NEED INDIVIDUAL REMOVAL STRATEGY IN SCHOOL LUNCH].

Gibberellin-regulated protein (GRP) is a newly discovered allergen in systemic fruit allergies. The kind of fruits which cause allergy is extensive as GRP is universally included in plants. Two children with GRP allergy were reported. Case 1: A 6-year-old boy experienced anaphylaxis while running after school lunch, which included canned peaches. A skin prick test (SPT) and blood examination suggested that he had peach GRP allergy. Six months and three years later, he experienced a similar episode after eating apple and citrus flesh, respectively. Case 2: An 11-year-old boy experienced anaphylaxis while running after consuming canned peaches during school lunch. A SPT implied that he had peach GRP allergy. However, a similar episode occurred after eating strawberry flesh 18 months later.Patients with GRP allergy often have one or more allergies to fruits other than peaches, as in these cases, and relevant fruits differ depending on the case. Particularly, clinicians should recognize that apple and citrus fruits are frequently included in school lunches as fruit flesh and as flavoring or seasoning in ready-made sauces or dressings. Therefore, an appropriate removal strategy should be considered in school lunches depending on each case of GRP allergy.

Atypical diarrhoeagenic Escherichia coli in milk related to a large foodborne outbreak.

A foodborne outbreak related to milk cartons served in school lunches occurred in June 2021, which involved more than 1,800 cases from 25 schools. The major symptoms were abdominal pain, diarrhoea, vomiting, and fever. Although major foodborne toxins and pathogens were not detected, a specific Escherichia coli strain, serotype OUT (OgGp9):H18, was predominantly isolated from milk samples related to the outbreak and most patients tested. The strains from milk and patient stool samples were identified as the same clone by core genome multilocus sequence typing and single-nucleotide polymorphism analysis. The strain was detected in milk samples served for two days related to the foodborne outbreak at a rate of 69.6% and levels of less than ten most probable number/100 mL but not on days unrelated to the outbreak. The acid tolerance of the strain for survival in the stomach was similar to that of enterohaemorrhagic E. coli O157:H7, and the same inserts in the chu gene cluster in the acid fitness island were genetically revealed. The pathogenicity of the strain was not clear; however, it was indicated that the causative pathogen was atypical diarrhoeagenic E. coli OUT (OgGp9):H18.

Energy and nutrient content of school lunches provided for children attending school-based nurseries: a cross-sectional study.

OBJECTIVE: To nutritionally analyse lunches provided for 3-4-year-old children attending school nurseries. Energy and nutrient content are compared with nutrient frameworks underpinning voluntary guidelines for early years settings (EYS) and mandatory standards for infant schools (4-7-year-olds). DESIGN: A cross-sectional study, recording all main meals, vegetarian meals, jacket potato options, sandwich options and all desserts and accompaniments provided over 5 consecutive days in each school. Two portions of each meal were collected each day and weighed. Recipe and portion weight data were entered into nutrient analysis software. SETTING: School nurseries where lunch was provided by the school. SUBJECTS: Nine schools, providing a total of 161 meals. RESULTS: Lunches contained more energy (1881 kJ/450 kcal), fat (15·5 g), free sugars (10·5 g) and Na (424 mg) than suggested by the nutrient framework for EYS. Carbohydrate (60·6 g), protein (16·8 g), fibre (6·7 g), Fe (2·4 mg), Zn (2·0 mg), Ca (202 mg), vitamin A (304 µg) and vitamin C (19 mg) also exceeded minimum recommendations. Compared with a revised nutrient framework for infant schools, energy was within range, whilst saturated fat, free sugars and Na were above maximum recommendations for this age group, and Zn was below. Sandwich meals were lower in vitamin C (P < 0·001-P = 0·05) and Fe (P = 0·012-P = 0·017) and higher in Na (P < 0·001-P = 0·003) and Ca (P < 0·001-P = 0·05). CONCLUSION: Lunches provided for children attending school nurseries are more in line with the framework for 4-7-year-olds. Free sugars, saturated fat and Na are areas of concern consistent with previous studies. Protein is three times more than recommended. Large portions of cakes and biscuits contribute to excess energy provision.

Improving school lunch menus with multi-objective optimisation: nutrition, cost, consumption and environmental impacts.

OBJECTIVE: To support school foods programmes by evaluating the relationship between nutritional quality, cost, student consumption and the environmental impacts of menus. DESIGN: Using linear programming and data from previously served menu items, the relationships between the nutritional quality, cost, student consumption and the environmental impacts of lunch menus were investigated. Optimised lunch menus with the maximum potential student consumption and nutritional quality and lowest costs and environmental impacts were developed and compared with previously served menus (baseline). SETTING: Boston Public Schools (BPS), Boston Massachusetts, USA. PARTICIPANTS: Menu items served on the 2018-2019 BPS lunch menu (n 142). RESULTS: Using single-objective models, trade-offs were observed between most interests, but the use of multi-objective models minimised these trade-offs. Compared with the current weekly menus offered, multi-objective models increased potential caloric intake by up to 27 % and Healthy Eating Index scores by up to 19 % and reduced costs and environmental impacts by up to 13 % and 71 %, respectively. Improvements were made by reducing the frequency of beef and cheese entrées and increasing the frequency of fish and legume entrées on weekly menus. CONCLUSIONS: This work can be extrapolated to monthly menus to provide further direction for school districts, and the methods can be employed with different recipes and constraints. Future research should test the implementation of optimised menus in schools and consider the broader implications of implementation.

Parental support for free school lunches in Australian primary schools: associated factors and perceived barriers.

OBJECTIVE: (1) To explore the feasibility of such programmes in Australia, this study examined parents' views on free school lunch provision. (2) To examine the associations between parents' demographic and personal characteristics and their support for free universal school lunches. DESIGN: An online cross-sectional survey of parents. SETTING: Australia, April 2021. PARTICIPANTS: Seven hundred and eighty-seven parents took the survey. They had a mean age of 40. The respondents were predominantly female (95 %) and had a university degree (72 %). RESULTS: Fifty-three percentage of the respondents agreed that all students should have access to healthy and well-balanced, free school lunches. Parents were concerned about healthiness, catering, allergies and cost of school-provided school lunches. Ethnic background, universalism values and education levels were significantly associated with support for free school lunch provision. Non-native English-speaking parents were almost three times more likely to support free universal lunches in primary schools than their native English-speaking counterparts. Parents with higher universalism-concern values were more likely to endorse free lunches in primary school. However, the level of education was negatively associated with parents' support for free school lunches. CONCLUSIONS: The survey results highlight the complexity of parental views on free school lunch provision. Parents' concerns regarding lunches should be considered in developing school lunch programmes that meet the needs and preferences of diverse communities. These findings can be used to guide future primary school lunch provision initiatives.

A qualitative study exploring the perceptions of children, parents and school staff towards the development and implementation of school lunch provision within primary schools in the Netherlands.

BACKGROUND: There is no tradition of serving school lunches in primary schools in the Netherlands. Most children tend to bring their own packed lunch, however these are often nutritionally suboptimal. While school lunch provision can aid healthy eating behavior amongst children, its introduction would constitute a profound change for children, parents and school staff. Therefore, this qualitative study aims to explore children's, parents and school staffs' perceptions of both the current lunch situation and the implementation of school lunch provision within primary schools in the Netherlands. METHODS: In this qualitative study we conducted nine interviews with school principals, 98 interviews with children, and held six focus groups with teachers and six with parents at primary schools in two Dutch cities. The data was analysed via iterative coding. RESULTS: The results showed that most children and parents are satisfied with the current lunch situation, although existing school food policies are not always put in place. Most teachers felt that children had insufficient time to consume their lunch in the current situation. The children were generally positive about the idea of a school lunch, and stressed that it was important to have the ability to choose. While both parents and school staff saw school lunch provision as an opportunity to educate families about healthy food options, they also expressed concern about who would be responsible, as well as the financial and organizational implications of its introduction. CONCLUSIONS: Perceptions of children, parents and school staff about a school provided lunch are mixed. A complex intervention such as a new school lunch program is difficult to envisage for all parties involved and more research is needed regarding the effects, organization, logistics and the costs of school lunch provision in the Netherlands.

School lunch portion sizes provided for children attending early years settings within primary schools: A cross-sectional study.

BACKGROUND: In England, many children attend an early years' setting (EYS) that is part of a primary school. Where a school lunch is available, this is often the same for both EYS and school children. This study explored how school lunch portion sizes served for 3-4-year-old EYS children compared with portion size guidance for EYS and schools, given that recommendations are different for EYS and school-aged children. METHODS: Twelve schools were recruited in four local authorities, each of which provided a school lunch to children attending EYS (aged 3-4 years) and reception classes (aged 4-5 years) from the same menu. Two portions of each menu item were weighed, each day, for five consecutive days. Mean, median, standard deviation and correlation coefficient were calculated for each food item. RESULTS: Most caterers reported serving the same-sized portions to both 3-4-year-olds and 5-7-year-olds. Food items falling outside of the typical range for EYS were more commonly above the range (10 food items) than below it (6 food items). Notably, portions of cakes and biscuits were larger than recommended. Portion weights falling outside of the recommended range for 4-10-year-olds were usually too small (12 of 14 items). Some foods provided by the schools in the study did not have typical portion sizes for EYS as they were not 'good choices of foods to serve'. CONCLUSIONS: These results suggest caterers may not be following guidelines appropriate for all the children they are catering for.

Parental perception of children's school lunch milk.

School lunch programs are mandated by the US Code of Federal Regulations to serve pasteurized milk that is skim or 1% fat and fortified with vitamins A and D. In recent years, proposals have been made to alter nutritional requirements for school lunches and school lunch milk, including changes to the milk fat and flavor options available. The objective of this study was to evaluate parental understanding and perception of school lunch milk to better understand how changes to school lunch milk are perceived by parents. Four focus groups (n = 34) were conducted with parents of school-aged children (5-13 yr) who purchased milk as part of a lunch at school. Participants were asked about school lunch milk, including nutritional content, packaging, and flavoring. Focus groups included a build-your-own milk activity and discussion of children's milk products currently available on the market. Two subsequent online surveys were conducted with parents of school-aged children (survey 1, n = 216; survey 2, n = 133). Maximum difference scaling was used to evaluate what beverages parents would prefer their child to drink at school (survey 1) and which attributes of chocolate milk for children were most important to parents (survey 2). An adaptive choice-based conjoint activity (survey 1) included flavor, milk fat, heat treatment, label claims, and packaging type. Both surveys included questions to evaluate knowledge of milk nutrition and attitudes regarding milk and flavored milk. Agree/disagree questions were used in both surveys to assess parental opinions of school lunch milk. Survey 2 also included semantic differential (sliding scale) questions to assess parental opinions of chocolate milk and their acceptance of sugar alternatives in chocolate milk served in schools. Parents were familiar with the flavor options and packaging of school lunch milk, but expressed limited familiarity with school lunch milk fat content. Parents perceived milk to be healthy and a good source of vitamin D and calcium. From survey results, parents placed the highest importance on school lunch milk packaging, followed by milk fat percentage and flavoring over label claims and heat treatment. The ideal school lunch milk for parents was unflavored (white milk) or chocolate, 2% fat, and packaged in a cardboard gabletop carton. For school lunch chocolate milk, 3 distinct clusters of parents with differing opinions for children's chocolate milk were identified. Parents are largely unfamiliar with the specific attributes and nutritional profile of milk served in schools but believe that schools should offer milk to their children as part of breakfast and lunch. Parents in both surveys also displayed a preference for 2% fat milk over low-fat options, which provides actionable insight for both governmental bodies determining educational and nutritional policies for school meals and fluid milk producers seeking to optimize their products intended for schools.

Exploring Australian children's perceptions of a school-provided lunch model using a story completion method.

Children in Australia currently bring a packed lunch to school from home. Many children are not consuming a healthy diet at school. There is interest from key stakeholders (e.g. education and the non-government sector, food service and parents/caregivers) to transform the Australian system to a school-provided model to improve children's diets, reduce parental burden and address food insecurity. To facilitate a successful transition to this system, it is important to consider the views of the children. We aimed to explore Australian primary school children's perceptions of a hypothetical school-provided lunch model. To achieve this aim, we undertook a qualitative study using the story completion method. Twenty-one grade-five children, from one public primary school in South Australia, participated in a once-off data collection session. Children were given a brief story stem and asked to complete a story about a hypothetical school-provided lunch scenario. The story data were analysed using thematic analysis. Four main themes were generated: the eating environment, the food provided, processes of the mealtime and time. The desire for choice was an additional overarching theme that cut across all themes. Our study provides the first exploration of South Australian children's perceptions of hypothetical school-provided meals. These insights can be used to co-design an acceptable school food system with children to create a positive eating environment that supports healthy eating habits they can carry forward into adulthood.

Impact of COVID-19 School-Related Policies in Ontario on Parents' School Lunch Packing Habits.

Purpose: COVID-19 has disrupted the daily routines of many Canadian families. In Ontario, provincially mandated public health measures have resulted in significant changes to school policies, including those related to food. The impact of COVID-19 related school food policies on parental lunch packing habits is unknown; therefore, this study investigated how school-related COVID-19 policies have impacted parental school lunch packing habits.Methods: Parents (N = 287) of school-aged children were recruited from parent-specific Facebook groups across Ontario, Canada, to complete an online survey regarding lunch packing habits. This survey was developed based on findings from a previously conducted scoping review. Open-ended survey responses were inductively analyzed.Results: Three over-arching themes were constructed: (1) Food Programs and COVID-19; (2) Schedule Changes; and (3) School Policy Changes. Parents explained that the cancellation or modification of food programs at schools, changes to the length of time children are given to eat at school, and removal of access to microwaves, garbage cans, and teacher assistance during lunch have forced parents to change their lunch packing habits.Conclusion: Findings from this study demonstrate a need for better support to help ease the burden parents experience when packing their child's school lunch, during an already extremely stressful time.
