RESUMEN
BACKGROUND: The Universal Infant Free School Meal (UIFSM) policy was introduced in 2014/15 in England and Scotland for schoolchildren aged 4-7 years, leading to an increase in school meal uptake. UK school meals are known to be healthier and less industrially processed than food brought from home (packed lunches). However, the impact of the UIFSM policy on the quantity of ultra-processed food (UPF) consumed at school during lunchtime is unknown. This study aimed to evaluate the impact of the UIFSM policy on lunchtime intakes of UPF in English and Scottish schoolchildren. METHODS: Data from the UK National Diet and Nutrition Survey (2008-2019) were used to conduct a difference-in-difference (DID) natural experiment. Outcomes included school meal uptake and the average intake of UPF (% of total lunch in grams (%g) and % total lunch in Kcal (%Kcal)) during school lunchtime. The change in the outcomes before and after the introduction of UIFSM (September 2014 in England, January 2015 in Scotland) in the intervention group (4-7 years, n = 835) was compared to the change in an unexposed control group (8-11 years, n = 783), using linear regression. Inverse probability weights were used to balance characteristics between intervention and control groups. RESULTS: Before UIFSM, school meal uptake and consumption of UPFs were similar in the intervention and control groups. The DID model showed that after UIFSM, school meal uptake rose by 25%-points (pp) (95% CI 14.2, 35.9) and consumption of UPFs (%g) decreased by 6.8pp (95% CI -12.5,-1.0). Analyses indicated this was driven by increases in minimally processed dairy and eggs, and starchy foods, and decreases in ultra-processed salty snacks, bread and drinks. The differences were larger in the lowest-income children (-19.3 UPF(%g); 95% CI -30.4,-8.2) compared to middle- and high-income children. Analyses using UPF %Kcal had similar conclusions. CONCLUSIONS: This study builds on previous evidence suggesting that UIFSM had a positive impact on dietary patterns, showing that it reduced consumption of UPFs at school lunchtime, with the greatest impact for children from the lowest-income households. Universal free school meals could be an important policy for long term equitable improvements in children's diet.

INTRODUCTION: The majority of children fails to have a healthy diet. Providing a healthy lunch at school is a way to target all children, regardless of ethnic and socioeconomic background. This study aims to investigate the effectivity and feasibility of a co-created healthy school lunch in disadvantaged neighbourhoods of the city of Rotterdam, the Netherlands. METHODS AND ANALYSIS: This is a cluster randomised cross-over trial with five participating primary schools. Schools will be randomised to have an 18 week healthy school lunch the first or second half of the academic year. The other half of the academic year, children will bring their own lunch from home. A tailored lunch concept for each school will be co-created with school staff, parents, children and key-stakeholders.Primary outcome is the dietary content of children's lunches, assessed by observations for all children. Secondary outcomes include healthy lunch-related parameters, like general dietary behaviour, perceived health, taste preferences, concentration in class, and some feasibility outcomes, like satisfaction, implementation at school and affordability for parents. Secondary outcomes will be assessed by questionnaires for children (grades 5-8), parents and teachers. The observations and questionnaires for children and parents will be completed at baseline (September 2023), half way the academic year (January-February 2024) and at the end of the academic year (June-July 2024). Teachers will complete a monthly questionnaire starting in September 2023. ETHICS AND DISSEMINATION: This study obtained ethical approval from the Institutional research Review Board Erasmus MC of Rotterdam, the Netherlands. Informed consent will be collected from all participants (parents, teachers and children 12 years or older) and/or their parents (for children under the age of 16). The findings will be disseminated by conference presentations and publications in scientific peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT06058325.

Background/Objectives: During 2022-2023, the School Lunch Project (SLP) provided free nutritious cooked lunches 1-4 days per week to Kinder to Grade 10 students attending 30 schools in areas of high disadvantage in Tasmania, Australia. This analysis examined if the SLP was associated with student attendance. Methods: Staff (teachers, support staff, and principals) from 12 schools completed an online survey and/or participated in focus groups/interviews. Government-held, objectively measured, grade-level attendance data were provided for 17 SLP and 11 matched comparison schools for 2018-2023. Linear mixed models compared attendance on school lunch and non-school lunch days in SLP schools. Difference-in-difference regression compared attendance between SLP and comparison schools. Qualitative data were analysed thematically. Results: Sixty-five staff completed surveys, where 22% reported that increased attendance was a benefit of the SLP. Similar findings were observed in the staff focus groups/interviews (N = 51). Mean attendance was similar on school lunch and non-school lunch days among the SLP schools during 2022 (difference: 0.04, 95% CI: -0.5, 0.6) and 2023 (difference 0.1, 95% CI: -0.2, 0.4) and similar between SLP and comparison schools (average treatment effect in the treated: 1.2, 95% CI: -0.7, 3.0). Conclusions: The SLP was perceived by some staff to improve attendance but was not associated with objectively measured attendance examined at the grade level.

Obesity in adolescents is a global health concern associated with several diseases and complications in adulthood. Obesity has been reported to be strongly associated with oral habits. To investigate the association between tooth brushing during lunchtime and the prevalence of obesity among adolescents in a nationally representative sample of South Korean adolescents. Data from the 2018-2021 Korea Youth Risk Behavior Web-Based Survey were used in this cross-sectional study. Obesity was measured based on the body mass index. The chi-square test was used to investigate and compare tooth brushing habits during lunchtime in the study population, and multivariate logistic regression analysis was performed to analyze the relationship between tooth brushing during lunchtime and the prevalence of obesity. The odds of obesity were lower in the group that brushed their teeth during lunchtime (adjusted odd ratio: 0.90, 95% confidence interval: 0.88-0.93). Furthermore, the odds of obesity were significantly higher in high school students; boys; those with a low household income, low subjective health status awareness, medical history (asthma or atrophy), and history of sealant use; and those who responded after the coronavirus disease 2019 pandemic. A significant inverse relationship was found between tooth brushing habits during lunchtime and the prevalence of obesity. This relationship was consistent regardless of socioeconomic and lifestyle factors.

BACKGROUND: Nutrition has an impact on development and linear growth. However, a few studies examine the connections between children's age-standardized height and their nutritional status and diet quality. OBJECTIVES: This study aimed to find a relationship between dietary consumption and height for age among school students under a web-based Thai school lunch program. METHODS: Anthropometric data and nutrient consumption were obtained from 24-hour records. Nutrient consumption was calculated using Inmucal. The parent and custodian's data were from the electronic health records. RESULTS: Children's heights were not correlated with parents' heights (P<0.720). Moreover, children with low height-for-age Z-score (HAZ) had significantly lower intakes of minerals (iron, magnesium, and selenium) and vitamins (B6, B12, C, and E). On the other hand, magnesium, selenium, vitamin B12, and vitamin E intakes of the children with normal HAZ were higher than their custodians. CONCLUSION: The Thai school lunch program effectively maintains the normal HAZ of children. Nutritional education in the community is recommended.

Purpose: To analyze the cariogenicity of meals served in a pre-kindergarten program and its potential influence on early childhood caries (ECC) risk in socioeconomically disadvantaged children. Methods: This study examined 123 school-provided meals over 43 days at the United Nation Childhood Development Center, part of the Oakland Unified School District pre-kindergarten program. Using cariogenicity indices developed by Evans et al., all items served were assessed for the cariogenic potential of both food and beverages. Results: The mean daily cariogenicity scores were 6.57±1.3 (standard deviation) for food and 2.89±0.78 for beverages. Breakfast foods were significantly more cariogenic than those served for lunch or supper (P<0.05). The mean daily calorie intake was 1,459±336, with lunch containing statistically higher calorie items compared to supper (P<0.05). While liquids may not significantly contribute to caries risk, breakfast foods emerged as a potential concern. Conclusions: This study's findings suggest that the food provided in school meals, particularly breakfast items, may impact early childhood caries risk among socioeconomically disadvantaged children. Given the prevalence of ECC and its societal burden, integrating assessments of food and beverage cariogenicity into school meal planning could be instrumental in mitigating ECC incidence. Collaboration between the United States Department of Agriculture and school districts in considering the cariogenic potential of foods may contribute to improved oral health outcomes in early childhood.

Sensory cues like music can influence our behaviour towards food. In the present study, the effect of music on hunger, fullness, desire to eat and liking of foods, while viewing real lunch food items, was investigated. To this end, emotions and physiological measures were obtained to understand the changes in hunger, fullness, desire to eat and liking. The study aimed to examine changes in hunger, fullness, desire to eat, and liking when viewing a lunch meal under silent and varying music conditions. Additionally, the study explored the potential role of emotions to explain these changes. A crossover experimental design was employed using 50 participants (17 males and 33 females) who observed lunch food items during a silent condition (control), or while listening to either liked or disliked music. The findings demonstrate the cross-modal influence of music on hunger and food liking ratings when viewing food. Hunger ratings were higher and more negative emotions were evoked while viewing lunch food items and listening to disliked music. In contrast, in the silent and liked music conditions, which elicited more positive emotions, there were increased ratings of healthy and unhealthy food pleasantness, overall food liking, and food satisfaction. Electrophysiological measures of heart rate (HR) and skin conductance (SC) were obtained while listening to music and viewing a lunch meal. Viewing food items while listening to disliked music evoked negative emotions and significantly increased SC compared to liked music or silent conditions. Viewing the food items under the silent condition evoked positive emotions and significantly increased HR compared to listening to liked and disliked music. This study showed that the participants' emotions, hunger level, liking, and electrophysiological responses when viewing food are influenced by music that varied with liking. Results from this study may assist in enhancing dining experiences, as well as influencing food choices and satisfaction with meals.

Vegetable provision at schools in the UK has increased over recent years; however children still eat few of the vegetables that are served to them. Two experimental pilot and feasibility studies implemented a vegetables-served-first (study 1) plus experiential learning (study 2) approach to increase children's (3-5 years and 4-7 years respectively) vegetable consumption at school lunchtimes. Both studies involved vegetables-served-first 10-min before the rest of the meal, with experiential learning techniques (repeated exposure, "veg-first" dinner plates, vegetable songs, videos, and nutrition education) complementing the vegetable service in study 2. Study 1 (n = 38) found that vegetables-served-first, compared with serving all foods together, increased vegetable intake by â¼12 g. Study 2 (n = 69) found that vegetable consumption depended on individual schools. Schools where vegetable intake was low showed increases in consumption during intervention weeks, whereas schools with high vegetable intake showed little change. Acceptability of interventions was found to be good for children and schools that participated, although concerns about time to serve vegetables first and COVID-related environmental restrictions reduced feasibility for some schools. Child engagement could also be improved by offering a wider variety of vegetables during repeated exposure to reduce monotony. Future research should design interventions using co-design methods including schools to suit their context best, whilst also addressing the problem with a systems approach. Interventions which focus on child learning through experience need to take account of specific school environments including curricular needs, resources available for school lunch (including both time and space), provision of food, support from teachers and parents, and the culture around eating (e.g. encouragement, pressure to eat, lunchtime competing with playtime). Joined-up systems approaches could enhance both provision and uptake of vegetables at school meals.

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.

INTRODUCTION: Mid-day meal programmes (MDM) were introduced in India to improve school attendance, nutritional status and educational outcomes of school children. Numerous primary studies have examined the impact of the MDM programmes on both nutritional and educational outcomes in various settings across the country. However, synthesising the findings from these studies has been challenging. To address this gap, we conducted a systematic review to assess the effects of MDM programmes on the nutritional and academic outcomes of school children in India. METHODS: A comprehensive literature search was conducted, and relevant studies published between 1997 and 2022 were included. Two reviewers independently conducted study selection, data extraction and risk of bias assessment. The results were synthesised descriptively. RESULTS: The systematic review included 31 studies. Among them, 16 studies focused on academic outcomes, while 18 studies reported children's nutritional status. Studies on MDM Scheme (MDMS) in children show mixed results on nutritional outcomes. While some studies show marginal improvements in height and weight measurements, others show no significant improvement. Regular MDMS access improves enrollment, attendance and retention rates for children, with lower dropout rates and higher academic achievement. However, its impact on academic performance remains unclear. CONCLUSION: The MDM programme in India was effective in improving the academic achievement and a few nutritional outcomes of school children, underscoring the importance of sustaining MDM programmes in India. PROTOCOL REGISTRATION NUMBER: The review was prospectively registered in PROSPERO (CRD42023391776). Available from: https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42023391776.

BACKGROUND: Despite the many benefits of school meals, not all students participate. One reason students may not participate in school meals is because they instead purchase breakfast or lunch from food outlets located around schools that mostly carry unhealthy items. This study examined whether school participation in the Community Eligibility Provision (CEP), which allows qualifying schools to serve free meals to all students, moderated the association between the community food environment around schools and student meal participation. METHODS: This study employed a longitudinal repeated-measures design using school-level data collected between 2014 and 2020 within four low-income school districts (n = 126 schools) in the US. We obtained meal participation data from state records and created a measure characterizing the community food environment within 0.25 miles of schools (characterized as low-density of unhealthy food outlets vs. high-density of unhealthy food outlets) through a latent class analysis. Regression analysis estimated associations between community food environments, CEP participation, and participation rates in school breakfast and school lunch, assessed in separate models. RESULTS: While no moderating effect of school CEP status was observed for breakfast or lunch participation, school breakfast participation was predicted to be 4% lower in high-density food environments than in low-density environments (P-value = .049) among non-CEP schools, and there was no difference in participation by the community food environment among CEP-participating schools. Differences in breakfast participation by the community food environment among non-CEP schools were mostly attributable to middle/high schools, with participation predicted to be 10% lower in high-density environments than in low-density environments among non-CEP middle/high schools (P-value < .001), whereas such a difference in participation was not observed among non-CEP elementary schools. CONCLUSIONS: Negative associations between food environment around schools and school breakfast participation were observed only among middle and high schools not participating in CEP, suggesting that policy actions to increase access to free school meals may benefit students, particularly older children and adolescents.

School lunch plays an important role in children's healthy growth. Previous investigations revealed many problems with school lunches, including unreasonable dietary structure and insufficient micronutrients. This study aimed to assess the dietary structure and nutritional quality of lunches in Nanjing primary and middle schools. A stratified cluster random sampling method was used to select 44 schools that supply lunch in 12 districts in Nanjing, with two primary and two middle schools in each district. Twenty-four primary and twenty middle schools were selected. The Mann-Whitney U test was used to explore the influencing factors. Findings revealed a serious shortage of milk and fruit in school lunches; supply of eggs, fish, shrimp, and shellfish was less than half of the recommended quantity; livestock and poultry supply exceeded the recommended level by over four times. Energy and nutrition intake were suboptimal. Provision of energy, carbohydrates, vitamins (A, B1, B2, and C), calcium, and iron in urban primary schools was significantly higher than that in non-urban primary schools. The same pattern of significantly higher nutrients was equally seen in urban middle schools compared with non-urban middle schools, indicating that food supply was affected by regional economies. Therefore, it is urgent to improve the quality of lunches, with a particular focus on those in non-urban areas.

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/ ).

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.

Research has drawn contradictory conclusions as to whether humans adjust meal size based on meal energy density (ED) or exhibit 'passive overconsumption'. Recent observational research has suggested that meal EDs greater than 1.7-2 kcal/g are compensated for through consumption of smaller meal sizes. We tested the relationship between ED and meal size by examining energy intake of meals at three levels of ED: low (â¼1.0 kcal/g), medium (1.7-2.0 kcal/g) and high (>3.0 kcal/g). Two randomised, crossover experiments were conducted with adult participants. In experiment 1 (n = 34, 62% female, mean age 37.4 years), participants were served a lunch including a familiar low, medium or high ED dessert to eat ad libitum. In experiment 2 (n = 32, 66% female, mean age 36.4 years), participants were served a lunch meal manipulated to be low, medium or high ED to eat ad libitum. For experiment 2, later energy intake (post-meal energy intake) was also measured. In experiment 1, participants consumed a similar amount of energy from the low vs. medium ED food. The high ED food was associated with an increased intake of approximately 240 kcals compared to medium (p < 0.001, Cohen's d = 2.31) and low (p < 0.001, Cohen's d = 4.42) ED foods. In experiment 2, there were no significant differences in meal size (grams) between ED meals, resulting in a largely linear relationship between meal ED and energy intake across the three ED conditions ('passive overconsumption'). There were no differences in later energy intake between ED conditions. Contrary to recent suggestions, foods higher in ED were not associated with adjustments to meal size and were associated with increased energy intake across two experiments. Reformulation of foods high in ED may be an effective population level approach to reducing energy intake and obesity.

Commercial environments and food acquisition methods significantly shape dietary practices and impact health. This study assesses dietary choices among Portuguese university students regarding vending machines, canteens, and lunches from home. It also evaluates their use of the university canteen and their tendency to bring lunch from home. This pilot cross-sectional study used a self-administered electronic questionnaire, made available in early 2023. Participants were recruited through snowball sampling. The study included 137 students from Portuguese higher education institutions, mainly women (74.5%), pursuing degrees or integrated Master's degrees (83.2%), primarily in health-related fields (55.5%). The median age was 21 years (20 to 23.5 years). About 70.0% regularly consumed food from vending machines, while approximately 60.0% brought lunch from home, avoiding the canteen. Factors such as convenience (48.5%), price (47.5%), product availability (40.6%), and taste (39.6%) mainly influenced vending machine choices. Monthly, chocolates, water, coffee, cookies, treats, and soft drinks were the most commonly acquired items, with coffee being the most frequent daily purchase. These findings provide insights for creating policies and initiatives to promote healthier and more accessible food options for students and strategies to encourage positive eating behaviors.

This systematic review and meta-analysis, spanning studies published between 1995 and 2021, investigates various aspects of lunches brought from home (LBFH) to school by children. These meals, in contrast to those provided by the National School Lunch Program (NSLP), lack strict nutritional standards. Despite the availability of NSLP lunches, â¼40% of US children opt for LBFH. This review aims to assess the food content and nutritional quality of LBFH, their adherence to NSLP standards in terms of nutrition and cost, effectiveness of intervention programs designed to enhance their nutritional quality and parental and student perceptions of LBFH. The comprehensive literature search yielded 28 eligible papers, with 16 included in meta-analysis. LBFH commonly include fruits (50%), yet vegetables (17%) and dairy (25%) are less prevalent. They frequently contain snacks (50%), sweets (48%), and sugar-sweetened beverages (31%). Compared with school lunches, LBFH exhibit lower levels of calcium, protein, iron, fiber, and vitamin A, and higher levels of carbohydrates and saturated fat. Intervention programs had no effect on quality of LBFH. On average, LBFH ($1.81) cost slightly less than lunches served at school ($1.98), without accounting for free/reduced-price meals in the calculation. The cost of school lunch for pre-k and kindergarten children became $11.32, nearly 4 times higher than that of LBFH ($2.92), after replicating the meal at home and accounting for meal preparation time. Parents preferred LBFH over school lunches because of concerns related to the quality of school meals served. This study concludes that LBFH are generally less nutritious compared with lunches provided by NSLP. Future research needs to further explore ways to improve parent perception of NSLP. Especially with many states making free meals available to all children, identifying effective ways in promoting and increasing NSLP participation can ensure more children have access to nutritionally balanced and affordable lunches.

People often fail to acknowledge external influences on their food intake, but there might be some circumstances in which people are willing to report that those external factors influenced their behavior. This study examined whether participants who believed that they had overeaten would indicate that the portion size they were served influenced their food intake. Participants (119 women) ate a pasta lunch at two separate sessions, one week apart. At the second session, participants were randomly assigned to receive either a regular portion of pasta (the same portion as the first session) or a large portion of pasta (a portion that was twice the size), and to receive false feedback about their food intake indicating that they had either eaten about the same as or substantially more than they had at the previous session. Participants were then asked to indicate the extent to which the amount of food served influenced how much they ate at that second session. Compared to participants who were informed that they had eaten the same amount across the two sessions, those who were informed that they ate more at the second session reported a stronger influence of the amount of food served if they also received a large portion of pasta, but not if they received a regular portion of pasta. These findings suggest that the willingness to implicate external influences (e.g., portion size) on one's food intake may be driven by a self-serving bias, providing an "excuse" for overeating. However, the external cue must be salient enough to be a plausible explanation for one's behavior.

Introducción: La disfagia es una condición que afecta la eficiencia de la deglución de los alimentos. Mundialmente, una tercera parte de los ancianos padece de algún grado de disfagia, representando un alto riesgo de malnutrición debido a que las carentes opciones alimenticias destinadas a este público no satisfacensus requerimientos nutricionales. Objetivo: Esta investigación tuvo como objetivo desarrollar formulaciones de almuerzos con textura modificada para pacientes con disfagia, a partir de materias primas típicas dominicanas. Materiales y métodos: Se realizaron dos almuerzos de diferentes composiciones [sancocho (S) y arroz con habichuelas y carnes (AHC)] y viscosidades (néctar: 51-350 mPa.s; miel: 351-1,750 mPa.s y pudín: 1,751- 2,500 mPa.s), a los cuales se les evaluó el análisis químico aproximado y la aceptación sensorial. Se utilizó un diseño completamente al azar, bajo arreglo factorial (2 x 3). Resultados: Se evidenciaron diferencias entre las medias de los tratamientos (p<0.05) para el contenido de humedad y de carbohidratos en relación con las composiciones; el análisis por viscosidades presentó diferencias en el contenido de humedad, grasa, proteínas y carbohidratos, en cuanto a la interacción entre las composiciones y las viscosidades hubo similitudes estadísticas en el porcentaje de cenizas y grasas. Se encontró que los tratamientos más viscosos y la composición S fueron mejor valorados y que el desempeño sensorial global de los almuerzos fue satisfactorio. Conclusiones: El alimento (tipo crema) con materias primas dominicanas, sensorialmente aceptado, podría ser utilizado y también aceptado, en pacientes con disfagia(AU)
Introduction: Dysphagia is a condition that affects the efficiency of food swallowing. Globally, one-third of the elderly population suffers from some degree of dysphagia, representing a high risk of malnutrition due to the lack of dietary options tailored to their nutritional requirements. Objective: This research aimed to develop modified texture lunch formulations for dysphagia patients using typical Dominican raw materials. Materials and methods: Two lunches of different compositions [sancocho (S) and rice with beans and meat (AHC)] and viscosities (nectar: 51-350 mPa.s; honey: 351-1,750 mPa.s and pudding: 1,751-2,500 mPa.s) were made and evaluated for proximate chemical analysis and sensory acceptance. A completely randomized design was used, under factorial arrangement (2 x 3). Results: Differences were observed between treatment means (p<0.05) for moisture and carbohydrate content concerning compositions; viscosity analysis showed differences in moisture, fat, protein, and carbohydrate content, while compositional and viscosity interactions exhibited statistical similarities in ash and fat percentage. It was found that the more viscous treatments and composition S were better rated, and overall sensory performance of the lunches was satisfactory. Conclusions: The food (cream type) with Dominican raw materials, sensorially accepted, could be used and also accepted in patients with dysphagia(AU)

Tasting food is the first step toward diversifying eating habits, and studies with children have typically focused on their sensory education and willingness to try new foods. While very little is known about how children taste foods during everyday mealtimes, EMCA (ethnomethodological and conversation analytic) research on adult tasting in naturalistic settings has demonstrated regular organisational patterns. This paper brings these two research areas together, using the insights of EMCA research on adult tasting to inform our understanding of how young children taste food during preschool lunches. Data are taken from a large corpus of video-recorded lunches in Sweden, in which children (3- to 6-year-olds) were eating with staff members. Discursive Psychology and multimodal Conversation Analysis were used to analyse the data. The analysis demonstrates how the sequential organisation of child tasting is similar to adult tasting, and how tasting practices are a collaborative, multisensory activity involving various embodied practices: from the orientation to food as 'to be tasted', the withdrawal of mutual gaze and exaggerated mouth movements, to the re-establishment of gaze accompanying the food assessment. In contrast to adult tasting, however, tasting during preschool lunches is often framed in terms of personal development of the child and of the individualising of taste within the framework of the institution. The findings thus provide further support for EMCA research on sensory practices and contribute to psychological research on children's eating by evidencing the importance of the interactional and institutional context on tasting as a sensory practice.
