Challenges With School Meal Provisions in K-12 Public Schools: Findings From the National School COVID-19 Prevention Study.

School meals play a vital role in supporting student health. Access to school meals was disrupted during COVID-19-related school closures, impacting student nutritional intake and household food insecurity. Data from the National School COVID-19 Prevention Study Survey and school staff focus groups were used to examine challenges to school meal provision in K-12 public schools. Data were analyzed using R and MAXQDA. Survey data indicated that most schools served breakfast and lunch in the cafeteria or classroom during the 2021-2022 school year. City schools were less likely to experience challenges with receiving the foods and supplies needed for school meal programs. Qualitative data revealed that school meal participation increased during the COVID-19 pandemic, however schools encountered challenges when implementing the program including staff shortages and supply chain issues. Findings from this study can help strengthen the K-12 school meal system to equitably serve students in future public health emergencies.

An automatic deep reinforcement learning bolus calculator for automated insulin delivery systems.

In hybrid automatic insulin delivery (HAID) systems, meal disturbance is compensated by feedforward control, which requires the announcement of the meal by the patient with type 1 diabetes (DM1) to achieve the desired glycemic control performance. The calculation of insulin bolus in the HAID system is based on the amount of carbohydrates (CHO) in the meal and patient-specific parameters, i.e. carbohydrate-to-insulin ratio (CR) and insulin sensitivity-related correction factor (CF). The estimation of CHO in a meal is prone to errors and is burdensome for patients. This study proposes a fully automatic insulin delivery (FAID) system that eliminates patient intervention by compensating for unannounced meals. This study exploits the deep reinforcement learning (DRL) algorithm to calculate insulin bolus for unannounced meals without utilizing the information on CHO content. The DRL bolus calculator is integrated with a closed-loop controller and a meal detector (both previously developed by our group) to implement the FAID system. An adult cohort of 68 virtual patients based on the modified UVa/Padova simulator was used for in-silico trials. The percentage of the overall duration spent in the target range of 70-180 mg/dL was 71.2 % and 76.2 % , < 70 mg/dL was 0.9 % and 0.1 % , and > 180 mg/dL was 26.7 % and 21.1 % , respectively, for the FAID system and HAID system utilizing a standard bolus calculator (SBC) including CHO misestimation. The proposed algorithm can be exploited to realize FAID systems in the future.

Experiences participating in federal nutrition assistance programs during the early months of the COVID-19 pandemic: an investigation in Vermont.

BACKGROUND: Federal nutrition assistance programs serve as safety nets for many American households, and participation has been linked to increased food security and, in some instances, improved diet quality and mental health outcomes. The COVID-19 pandemic brought new and increased economic, social, and psychological challenges, necessitating inquiry into how nutrition assistance programs are functioning and associated with public health outcomes. METHODS: Using data from a representative statewide survey administered in Vermont (n = 600) between July and September 2020, we examined participant experiences with major federal nutrition assistance programs: the Supplemental Nutrition Assistance Program (SNAP), the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC), and school meal programs. We explored quantitative and qualitative responses regarding perceptions of program utility, and used nearest neighbors matching analyses in combination with bivariate statistical tests to assess associations between program participation and food insecurity, perceived stress, and fruit and vegetable intake as indicators of dietary quality. RESULTS: One in four respondents (27.3%) used at least one federal nutrition assistance program. As compared to non-participants, we found higher rates of food insecurity among program participants (57.5% vs. 18.1%; p < 0.001), an association that persisted even when we compared similar households using matching techniques (p ≤ 0.001). From matched analyses, we found that, compared to low-income non-participants, low-income program participants were less likely to meet fruit intake recommendations (p = 0.048) and that low-income SNAP and WIC participants were less likely to meet vegetable intake recommendations (p = 0.035). We also found lower rates of perceived stress among low-income school meal participant households compared to low-income non-participants (p = 0.039). Despite these mixed outcomes, participants broadly valued federal nutrition assistance programs, characterizing them as helpful or easy to use. CONCLUSIONS: We found that federal nutrition assistance programs as a group were not sufficient to address food insecurity and stress or increase fruit and vegetable intake in the state of Vermont during the early months of the COVID-19 pandemic. Nonetheless, participants perceived benefits from participation in these programs. Optimizing the utility of nutrition assistance programs depends on critical examination of their functioning under conditions of great stress.

Dietary Patterns among Smokers and Non-Smokers: Findings from the National Health and Nutritional Examination Survey (NHANES) 2017-2018.

Diet behavior and nutrition are critical for maintaining health and improving quality of life. Cigarette smoking remains the leading cause of preventable death in the United States. Poor dietary choices, such as excessively frequenting restaurants, consuming ready-to-eat foods from grocery stores, and ingesting ultra-processed foods (like frozen meals and pizzas), can adversely impact health. Despite this, research comparing dietary behaviors between smokers and non-smokers is limited. Using data from the National Health and Nutritional Examination Survey 2017-2018, we analyzed diet behavior based on smoking status. Our findings reveal that smokers had a significant increase (90%) in the frequency of consuming frozen meals/pizzas in the past 30 days compared to non-smokers (coefficient: 1.9; 95% CI: 1.4, 2.6; p-value < 0.001). Additionally, over 70% of participants, regardless of their smoking status, were unaware of MyPlate, a nutritional guide created by the United States Department of Agriculture (USDA) to encourage Americans to make healthier food choices. There is an urgent need to increase public awareness of MyPlate and promote a better understanding of healthy dietary behaviors.

Effects of increasing the availability of vegetarian options on main meal choices, meal offer satisfaction and liking: a pre-post analysis in a French university cafeteria.

BACKGROUND: Changing the food environment is an important public health lever for encouraging sustainable food choices. Targeting the availability of vegetarian main meals served in cafeterias substantially affects food choice, but acceptability has never been assessed. We examined the effects of an availability intervention at a French university cafeteria on students' main meal choices, meal offer satisfaction and liking. METHODS: A four-week controlled trial was conducted in a university cafeteria in Dijon, France. During the two-week control period, vegetarian main meals constituted 24% of the offer. In the subsequent two-week intervention period, this proportion increased to 48%, while all the other menu items remained unchanged. Students were not informed of the change. Student choices were tracked using production data, and daily paper ballots were used to assess student satisfaction with the meal offer and liking of the main meal they chose (score range [1;5]). Nutritional quality, environmental impact, and cost of production of meal choices were calculated for each lunchtime. Food waste was measured over 4 lunchtimes during control and intervention periods. An online questionnaire collected student feedback at the end of the study. RESULTS: Doubling availability of vegetarian main meals significantly increased the likelihood of choosing vegetarian options (OR = 2.57, 95% CI = [2.41; 2.74]). Responses of the paper ballots (n = 18,342) indicated slight improvements in meal offer satisfaction from 4.05 ± 0.92 to 4.07 ± 0.93 (p = 0.028) and in liking from 4.09 ± 0.90 to 4.13 ± 0.92 (p < 0.001) during control and intervention periods, respectively. The end-of-study questionnaire (n = 510) revealed that only 6% of students noticed a change the availability of vegetarian main meals. The intervention led to a decrease in the environmental impact of the main meals chosen, a slight decrease in nutritional quality, a slight increase in meal costs and no change in food waste. CONCLUSIONS: Doubling availability of vegetarian main meals in a university cafeteria resulted in a twofold increase in their selection, with students reporting being more satisfied and liking the main meals more during the intervention period. These results suggest that serving an equal proportion of vegetarian and nonvegetarian main meals could be considered in French university cafeterias to tackle environmental issues. TRIAL REGISTRATION: Study protocol and analysis plan were pre-registered on the Open Science Framework ( https://osf.io/pf3x7/ ).

Family meals are associated with lower substance use in female adolescents.

Adolescents, especially female youth, who have more family meals tend to be at lower risk for substance use. The present study tested whether family meals relate to substance use count and frequency during high school, whether associations differ by gender, and whether other family-related variables explain these associations. A community sample of 316 adolescents (Mage = 16.40, SD = 0.74; 56.96% female; 41.77% Latine, 23.10% Asian American, 29.11% European American, 6.01% from other ethnic backgrounds including Middle Eastern and African American) reported the number of substances they have ever used and how often they used alcohol, marijuana, and cigarettes, and completed measures of parental support and family cohesion. Across 15 days, they reported whether they had a family meal, got along with parents, and spent leisure time with their family each day. Regression models tested associations between frequency of family meals and substance use, whether associations differed by gender, and whether associations were explained by other family-related variables. Results indicated that more frequent family meals were associated with lower substance use count and less frequent alcohol, marijuana, and cigarette use among female adolescents but not male adolescents. Other daily family experiences were unrelated to substance use, and family meal frequency was independently related to lower substance use after accounting for parental support and family cohesion. Taken together, more frequent family meals in high school may reduce substance use risk for female adolescents, and interventions could consider promoting family meals in addition to other positive family values.

Meals are more than nutrition for children with a malignant or non-malignant disorder with a gastrostomy tube: A qualitative study.

PURPOSE: To elucidate mealtime experiences of children hospitalized with a malignant or severe non-malignant disorder -and their parents-after a gastrostomy tube insertion. METHODS: A qualitative design involving a child-centred care approach was used. Parents of children aged 1-18 years old who had received a gastrostomy tube during treatment for a malignant or non-malignant disorder were included, as were the children themselves when aged 5-18 years old. Semi-structured interviews with 21 families were carried out and a thematic analysis performed. RESULTS: The findings were presented in four themes: changed meal conditions, a troublesome sensory dimension, aggravating obstacles and solving the unmanageable. Hospitalization involves challenges regarding environmental aspects, hospital food and side effects, contributing to impaired nutritional intake and aggravated mealtime situations. CONCLUSIONS: Hospital environment and hospital food have a profound impact on children's nutritional intake and mealtime situations. In addition, sensory aspects and side effects aggravate the child's motivation to eat, resulting in demanding meals. The families described a gastrostomy tube as a valuable strategy for improving mealtime situations.

[Study on determination methods and analysis of micronutrients in take-away meals].

OBJECTIVE: To comprehensively analyze the trace nutrient contents in take-away meals, the simultaneous detection method of common vitamins in take-away meals were explored based on the samples' matrix, and the content of trace nutrients in take-away meals was analyzed combined with inductively coupled plasma-mass spectrometry(ICP-MS) detection of common elements. METHODS: Fifty-seven take-away meals were collected randomly and analyzed. Vitamins were determined by high performance liquid chromatography-ultraviolet detector tandem fluorescence detector after pretreatment of samples including enzymatic digestion, hydrolysis and extraction. The separation was performed on a C_(18) column(250 mm×4.6 mm, 5 µm) with ion-pair acid reagents as the mobile phase for water-soluble vitamins and methanol for fat-soluble vitamins. Vitamin B_1, vitamin B_2, nicotinic acid, nicotinamide and vitamin A were detected by ultraviolet detector(UVD), while vitamin B_6 and E by fluorescence detector(FLD). Elemental analysis of calcium, magnesium, sodium, potassium, zinc, selenium and copper in the take-away meals was carried out according to GB 5009.268-2016 by ICP-MS to comprehensively evaluate the contents of micronutrients. RESULTS: Through optimization of chromatography and sample pretreatment conditions, the sensitivity of the established detection method can meet the needs of micronutrient evaluation with the detection limits and quantification limits of vitamins in the range of 0.002-0.098 mg/100 g and 0.007-0.327 mg/100 g, respectively. Good precision was obtained(<10%). The spiked recovery rates were 80.5%-103.8%(n=6). The result showed that the contents of micronutrients in take-away meals were generally low. The detection rates of vitamins ranged from 21.1% to 98.2%. CONCLUSION: The proposed method is simple and sensitive, and the contents of vitamins and elements determined were low in the collected take-away meals.

From Research to Knowledge Translation: Co-Producing Resources to Raise Awareness of Meals on Wheels in England.

BACKGROUND: Meals on Wheels (MoWs) could help adults with care and support needs continue living independently. However, many people are not aware that the service still exists in England, or that it could provide benefits beyond nutrition. OBJECTIVE: Working with an existing advisory group of six people with lived experience of MoWs (an adult who uses MoWs and people who have referred a family member to MoWs), this work aimed to co-produce knowledge translation resources (two infographics and a film) to raise awareness of MoWs and their benefits. METHODS: Four participatory online workshops were held in May-July 2023, to establish perceived high-priority themes from recent qualitative research that should be included in the resources, and preferences about message content, language, design, and how the resources should be disseminated. FINDINGS: The most important perceived MoWs benefits that the group agreed should be included in the resources were: the importance of a nutritious meal that requires no preparation; the service's reliability/consistency; the importance of interactions in reducing social isolation, and; the ease to commence the service. The group highlighted the need for language to be nontechnical and invitational, and for images to relate to respective messages, and be inclusive of anyone who could benefit from MoWs. Several routes for dissemination were proposed, highlighting the need to disseminate to the NHS, social care organisations and community groups. CONCLUSION: These co-produced resources could enhance adult social care delivery in England, as raising awareness of MoWs and their benefits could increase referral rates, so that more adults with care and support needs can benefit from the service. PATIENT OR PUBLIC CONTRIBUTION: An advisory group of people with lived experience of MoWs (users of the service and family referrers) participated in the workshops, extensively discussed the findings of earlier research, co-produced the knowledge translation resources, and advised on the implications and future dissemination steps. The group also provided informal feedback on a draft of this manuscript.

Relationship between Frequency of Meals Comprising Staple Grain, Main, and Side Dishes and Nutritional Adequacy in Japanese Adults: A Cross-Sectional Study.

Meals comprising a staple grain, a main, and side dishes (SMS meals) promote good dietary intake, yet limited studies have examined their multifactorial relationship with dietary intake. We investigated how demographic characteristics, lifestyle, and dietary habits affect the relationship between SMS meal frequency and nutrient intake adequacy. This cross-sectional study analyzed survey data from 331 Japanese adults (208 men and 123 women) aged 30-69 years in February 2019. SMS meal frequency was evaluated according to respondents' answers to how many days a week they consumed ≥2 daily SMS meals. Dietary intake was evaluated using the brief self-administered diet history questionnaire. Differences in nutrient intake adequacy among groups according to SMS meal frequency were determined using multiple logistic regression. Less frequent SMS meals correlated with a lower intake of protein, water-soluble vitamins, and certain minerals, with more individuals falling below the estimated average requirement for nutrient intake. However, no relationship was found between SMS meal frequency and nutrient intake concerning tentative dietary goals for preventing lifestyle-related diseases. Our findings indicate that adopting SMS meals could achieve adequate intake of some nutrients and enhance overall diet quality among Japanese adults.

Relationship between Household Shared Meal Frequency and Dietary Intake among Men and Women Aged ≥20 Years: Cross-Sectional Analyses Based on 2018 and 2019 National Health and Nutrition Surveys in Japan.

This study aimed to examine the relationship between the frequency of household shared meals and the intake of 17 food groups and 21 nutrients. Participants were 3310 men and 3386 women ≥20 years old living in a household of ≥2 members from 2018 and 2019 National Health and Nutrition Surveys in Japan. A one-day household dietary record was used to classify an individual's shared meal frequency and dietary intake. A shared meal is defined as an eating occasion (i.e., breakfast, lunch, and dinner) where ≥1 food item-other than sugars, fats and oils, beverages, and condiments-was recorded with an assigned approximated shared proportion. The shared meal frequency for each individual was classified into one of four categories: 0, 1, 2, and 3 times/day. Dietary intake was compared across the shared meal categories adjusted for age, occupation, household size, meal skipping, snacking, residential areas, and within-household correlations. Both men and women who had more frequent shared meals showed higher intakes of potatoes, vegetables, mushrooms, and condiments but less confectioneries and beverages. A higher shared meal frequency was also related to a higher intake of many (12/21) nutrients (e.g., protein, dietary fiber, and potassium). However, in women, there was a positive association between shared meal frequency and sodium intake. A higher frequency of household shared meals may be related to a more favorable dietary intake; except for concerns about sodium intake in women.

New Orleans school meal programs during the COVID-19 pandemic: challenges and innovations identified through qualitative interviews.

BACKGROUND: School meal programs are critical to reducing childhood food insecurity. This study identified challenges and innovations in school meal service in a disaggregated charter school system during COVID-19 in New Orleans, Louisiana. METHODS: Semi-structured qualitative key informant interviews were conducted with school officials and school food providers. Interviews were recorded, transcribed, and coded. Using an immersion-crystallization approach, patterns were identified. RESULTS: Nine participants described challenges and solutions/innovations in food service focused around five themes: food service, procurement and costs, staffing, communication and outreach, and collaborations and partnerships. Participants faced challenges in meal service logistics, procuring food and supplies, staffing shortages, timely communication, lack of city-wide coordination, and the need to rapidly shift operations due to an evolving pandemic. While the disaggregated system created challenges in a city-wide response, the decentralized system along with policy changes offered opportunities for flexibility and innovation in meal programs through new partnership and coordination between schools and community, development of new processes for food service and procurement, and diverse modes of communication. CONCLUSION: These findings add to the understanding of challenges faced and innovations implemented to continue school meal programs in a disaggregated school system. Collaboration with community organizations, leveraging resources, coordinated communication, and policies allowing for flexibility were key to response and should be encouraged to build capacity and resiliency in emergencies. In future city-wide emergency preparedness planning efforts, school leaders and food providers should be included in the planning to ensure continued equitable food access for students.

Identifying desirable attributes in dairy-rich breakfast and desserts for older adults.

In the next decade, the US anticipates a rapid increase in the older adult population, who also face an increased risk for disease. To reduce this risk, research should explore increasing intake of nutrient-dense foods and prepared meals that include dairy foods and utilize novel food processing that better retain nutrients. This study identified attributes that older adults (age = 65+) desire in dairy-rich ready-to-eat breakfasts and desserts, two meals important in healthy aging. Two online choice-based conjoint analysis surveys were fielded (one for breakfast and one for dessert) to determine desirable attributes amongst respondents (breakfast n = 211; dessert n = 300). Breakfast concepts included protein source, primary ingredient, type of dairy, and health claim. Dessert concepts included primary flavor, primary sweetener, type of inclusion, and health claim. Breakfast results revealed the desirable attributes included "no meat" (utility value [UV] = 0.138), "eggs" (UV = 0.384), "cheese" (UV = 0.034), and "good source of fiber" (UV = 0.163). Two consumer clusters were identified with cluster 1 (n = 151) desiring "red meat" as the protein source and cluster 2 (n = 60) preferring "no meat." The majority of respondents (86%) indicated a willingness to consume foods processed with a novel technique. For the dessert meals, desirable attributes were "chocolate flavor" (UV = 0.638), "sugar" (UV = 0.859), "fruit inclusions" (UV = 0.522), and "heart-healthy" (UV = 0.453). Dessert consumer cluster 1 (n = 145) desired chocolate desserts sweetened with sugar, whereas cluster 2 (n = 155) desired vanilla desserts sweetened with honey. Participants who preferred oral manipulation of food via "smooshing" expressed a higher liking for desserts with no inclusions. These results provide insight for future product development for older adults involving dairy products or novel processing techniques. PRACTICAL APPLICATIONS: This study shows that both sensory attributes and health claims are important considerations when developing ready to eat meals for older adults. For breakfast, providing a vegetarian option is important while for desserts, both chocolate and vanilla remain popular options.

Age-specific association between meal-skipping patterns and the risk of hyperglycemia in Korean adults: a national cross-sectional study using the KNHANES data.

BACKGROUND: Glucose metabolism regulation is influenced by age and meal skipping, although research on their interplay with hyperglycemia remains limited. This study aims to explore the intricate relationship between meal-skipping patterns and hyperglycemia risk across distinct age groups in South Korean adults. METHODS: Utilizing data from the Korea National Health and Nutrition Examination Surveys (KNHANES) conducted from 2013 to 2020, comprising 28,530 individuals aged 19 years and older, this study employed multivariable logistic regression models to examine the associations between meal-skipping patterns and the risk of hyperglycemia. RESULTS: Meal-skipping patterns were categorized into three groups: no skipping (NS), skipping breakfast (SB), and skipping dinner (SD). Age groups were defined as "young" (aged 19-44), "middle-aged" (aged 45-64), and "elderly" adults (over 65 years old). Among "young" adults, SB was associated with a 1.33-fold higher risk of hyperglycemia (OR = 1.33, 95% CI = 1.14-1.54) compared to NS. Conversely, in "elderly" adults, SD was linked to a 0.49-fold reduced risk (95% CI = 0.29-0.82) when compared to NS. Additionally, we observed that the Korean Health Eating Index (KHEI) scores, representing the quality of diet on a scale of 0 to 100, were consistently lower in SB compared to NS across all age groups. Intriguingly, specifically among the "elderly" group, this score was higher in SD compared to NS (p < 0.001). CONCLUSIONS: This study demonstrates age-specific variations in the association between meal-skipping patterns and the risk of hyperglycemia.

The Benefits and Challenges of Providing School Meals during the First Year of California's Universal School Meal Policy as Reported by School Foodservice Professionals.

States in the U.S. are newly implementing universal school meal (USM) policies, yet little is known about the facilitators of their success and the challenges they confront. This study evaluated the challenges and facilitators faced by school food authorities (SFAs) implementing California's universal school meal (USM) policy during its inaugural year (2022-2023) using an online survey. In March 2023, 430 SFAs reported many benefits, including increased meal participation (64.2% of SFAs) and revenues (65.7%), reduced meal debt (41.8%) and stigma (30.9%), and improved meal quality (44.3%) and staff salaries (36.9%). Reported challenges include product/ingredient availability (80.9%), staffing shortages (77.0%), vendor/distributor logistics issues (75.9%), and administrative burden (74.9%). Top facilitators included state funding (78.2%) and increased federal reimbursement (77.2%). SFAs with fewer students eligible for free or reduced-price meals (as opposed to SFAs with more) reported greater increases in meal participation and reductions in stigma but also more administrative burdens. Larger SFAs reported greater increases in revenues, staff salaries, and improvements in meal quality than smaller SFAs but also more challenges. Overall, California's USM policy has enhanced student access to healthy meals while mitigating social and financial barriers. Understanding California's experience can inform other jurisdictions considering or implementing similar policies.

Changing the default meal option at university events to reduce harmful environmental impacts: Six randomized controlled trials.

Animal agriculture is a leading contributor to greenhouse gas emissions and other harmful environmental impacts, which underscores the need to shift away from the consumption of animal-based products. One promising nudge intervention is making plant-based meals the default option, so we tested this approach at six different university events across four academic institutions for effecting sustainable dietary change. Event attendees pre-selected their meal on one of two randomly assigned RSVP forms: one with a plant-based default and one with a meal with meat default. The results from our randomized controlled trial showed that participants had a 43-percentage point greater probability of selecting the plant-based meal when it was indicated as the default option. This effect was similar across events and academic institutions, which indicates that this default intervention is generalizable and can be successfully implemented at university events. The combined effect of using plant-based defaults at these six events was an estimated reduction of 104,387 kg of CO2 emissions, 299.9 m2 of land use, 959.0 g of nitrogen use, and 259.5 g of phosphorus use, which represent roughly 45-46.2% reductions in harmful environmental impacts relative to the meals chosen when using a meat default. Given the significance and magnitude of these environmental benefits, our results support the widespread implementation of plant-based defaults for helping universities improve their sustainability.

A theoretical explanation for how a nutrition counseling and medically tailored meal delivery program benefitted participants living with lung cancer.

PURPOSE: The purpose of this study was to assess participants' perceptions and experiences while participating in a Food is Medicine medically tailored meal plus intensive nutrition counseling intervention to create a theoretical explanation about how the intervention worked. METHODS: This interpretive qualitative study included the use of semi-structured interviews with active participants in a randomized controlled trial aimed at understanding how a medically tailored meal plus nutrition counseling intervention worked for vulnerable individuals with lung cancer treated at four cancer centers across the USA. During the 8-month long study, participants in the intervention arm were asked to be interviewed, which were recorded, transcribed verbatim, and analyzed using conventional content analysis with principles of grounded theory. RESULTS: Twenty individuals participated. Data analysis resulted in a theoretical explanation of the intervention's mechanism of action. The explanatory process includes three linked and propositional categories leading to patient resilience: engaging in treatment, adjusting to diagnosis, and active coping. The medically tailored meals plus nutrition counseling engaged participants throughout treatment, which helped participants adjust to their diagnosis, leading to active coping through intentional self-care, behavior change, and improved quality of life. CONCLUSIONS: These findings provide evidence that a Food is Medicine intervention may buffer some of the adversity related to the diagnosis of lung cancer and create a pathway for participants to experience post-traumatic growth, develop resilience, and change behaviors to actively cope with lung cancer. Medically tailored meals plus intensive nutrition counseling informed by motivational interviewing supported individuals' adjustment to their diagnosis and resulted in perceived positive behavior change.

Children's liking for vegetarian and non-vegetarian school meals at the scale of a French city.

In Western countries, a behavioural shift towards more plant-based diets is helpful in protecting population and planet health. School canteens are an important public policy target to achieve this transition. Increasing the frequency of vegetarian meals in school canteens has been proposed as a solution to decrease greenhouse gas emissions while maintaining a good nutritional quality. However, vegetarian meals acceptance by children is key to limit unintended consequences such as increased food waste or increased nutritional inequalities. We aimed to examine children's liking for vegetarian and non-vegetarian main dishes at school canteens; and whether it varied across socioeconomic level. Connected scoring devices displaying a five-point smiley scale were installed in all the 38 primary school canteens of a French city, located in socially diverse neighbourhoods. Every day after their school lunch, children were asked to rate the main dish they had just eaten. During one school year, from September 2021 to June 2022, we collected 208,985 votes for 125 main dishes, including 32 vegetarian (i.e., no meat or fish) and 93 non-vegetarian dishes, for an average of 1672 (SD 440) votes per day across the 38 school canteens. We showed no difference in children's liking for vegetarian and non-vegetarian dishes. Additionally, the socioeconomic level of the schools was found to interact negatively with children's liking for vegetarian main dishes whereby vegetarian main dishes tended to be more liked in schools of lower socioeconomic level. In this French city, children's acceptance would not be a barrier to increase the frequency of vegetarian school meals and would not increase social dietary inequalities.

Parent perceptions of school meals and how perceptions differ by race and ethnicity.

Parental perceptions of school meals can affect student participation and overall support for school meal policies. Little is known about parental school meal perceptions under universal free school meals (UFSM) policies. We assessed California parents' perceptions of school meals during the COVID-19 emergency response with federally funded UFSM and whether perceptions differed by race/ethnicity. Among 1110 California parents of K-12 students, most reported school meals benefit their families, saving them money (81.6%), time (79.2%), and stress (75.0%). Few reported that their child would be embarrassed to eat school meals (11.7%), but more parents of White students than Hispanic students reported this. Many parents reported that their child likes to eat lunch to be with friends (64.7%); about half felt their child has enough time to eat (54.2%). Fewer parents perceived school lunches to be of good quality (36.9%), tasty (39.6%), or healthy (44.0%). Parents of Hispanic and Asian students had less favorable perceptions of school meal quality, taste, and healthfulness than parents of White students. Parents report that school meals benefit their families, but policy efforts are needed to ensure schools have the resources needed to address cultural appropriateness. Schools should address parental perceptions of meals to optimize participation, nutrition security, and health.
