ABSTRACT

The post-pandemic context has changed the modes for collecting data in sensory and consumer science. The objectives of this research were to analyze consumers' associations of food consistency and to study two virtual modes of the Free Word Association test (FWA). This test was administered to 209 consumers (180 women, 29 men, 18-45 years old) asynchronously (i.e. self-administered) and synchronously (i.e. face to face interviews). The Cognitive Salience Index (CSI) was calculated, and the structure of the social representation was analyzed. Correspondence analysis showed that food consistency was a mixture of concepts related to structure, hardness and several aspects of auditory (e.g., Crunchy, Crispy), tactile (e.g. Smooth, Spreadable) and oral texture (e.g., Creamy, Gummy). Slightly consistent food was associated with something soft, liquid or semisolid, and very consistent food to something hard and resistant. Consistent food was more related to "very" than to "slightly consistent." The CSI depended on the stimulus presented (p < 0.05). Regarding the social representation structure, the central core had the highest CSI for all stimuli (CSI ≥ 0.13, p < 0.05). Consumers defined "very consistent, consistent and slightly consistent food" by naming more foods in the synchronous mode than in the asynchronous one. In the asynchronous mode, consumers took more time to complete the test. The virtual FWA test (asynchronous or synchronous) showed some differences in the associations of term consistency, due to the lack of spontaneity in the first minute. It is important to adjust the methodologies to standardize the times in both modes.

ABSTRACT

BACKGROUND: Child food neophobia, i.e., rejection or avoidance of novel foods at a young age, is a prevalent nutrition problem that affects the quality of children's diet and impedes the development of healthy food preferences. Sensory sensitivity can relate to the degree of food neophobia, but previous studies rarely focused on the olfactory component of this problem in children. OBJECTIVE: We aimed to thoroughly examine the relationship between various aspects of olfactory sensitivity and food neophobia in children. METHODS: 246 children aged between three and nine years took part in a food neophobia assessment as well as in a comprehensive, psychophysical olfactory testing. RESULTS: We found that certain smell perception aspects such as lower odor liking, poorer odor identification ability as well as lower sensitivity to an unknown non-food odor all significantly predicted higher food neophobia in children. Among individual characteristics of either a child or a caregiver, only the child's age significantly and positively predicted food neophobia. The exploratory model looking into the role of family environment factors predicting self-reported food neophobia in children revealed that food neophobia was associated with lower control given to a child in this child's feeding process, as well as with a more frequent use of food as a reward in feeding. CONCLUSIONS: We suggest that suppressed olfactory perception and performance can play a unique role in child nutritional difficulties. The study inspires further considerations of olfaction-engaging interventions to counteract food-neophobia in children.

ABSTRACT

The purpose of this study was to understand the role of "dominance" definitions in the results of TDS applied to consumers. This study compared two temporal dominance of sensations (TDS) approaches - TDS-I - that attracts the most attention and TDS-II - most intense/strongest sensation - in the context of evaluating artisanal Minas cheeses from the Serra da Canastra and chocolate with different cocoa concentrations samples. TDS curves were constructed and a trajectory-based principal component analysis (PCA) was performed dominance rates at ten equally spaced time points. Additionally, difference curves, multiple factor analysis (MFA) and regression vector coefficient (RV coefficient) were performed to compare the two approaches. The findings showed that the two approaches produced similar results, suggesting that consumers interpret the terms dominant and intense in a similar way during TDS evaluations, the results were even closer at the chocolate study than at the cheese study. However, in both approaches were observed low dominance rates and differences between the sensation perception time, mainly in the evaluation of cheese flavor. This variability may be attributed to the complexity of the cheese's flavor and the varied interpretations of dominance among evaluators. Despite these differences, the approaches showed similar characterizations across the same samples, demonstrating high reproducibility and a strong ability to differentiate between samples. This study demonstrates that the choice between the terms dominant (which captures more attention) or intense (stronger) to guide consumers in performing the sensory test does not significantly influence the results. Consequently, it is possible to adopt greater freedom and flexibility in the terminology used to instruct participants in conducting the test.

ABSTRACT

Complementary feeding is a critical milestone for parents, who must decide the extent to which they feed their infants with homemade foods (HMFs) or commercial infant foods (CIFs). The current study focused on how parents perceive and evaluate CIFs and what drives them to use these products. Understanding the wide variety of factors that influence parents' decisions to use CIFs as a food source is crucial to helping them make more balanced food choices for their infants. Data from an online survey with 858 German parents revealed their negative perceptions of CIFs, particularly in terms of nutritional quality and texture, and concerns that CIFs contain higher levels of pesticides and heavy metals compared to HMFs, despite acknowledging the expertise of the infant nutrition industry. These perceptions were likely to be driven by the 'natural-is-better' belief and parents' desire for control over the ingredients in their infants' meals, contributing to their skepticism towards CIFs. Additionally, our study found that while many parents know traditional nutrition guidelines, they are less familiar with recent updates. Parents' benefit beliefs about CIFs and parents' trust in the food industry strongly influenced the use of CIFs, while infant age and parent gender had a less strong, yet significant influence on CIFs consumption. Overall, the present study offers new quantitative insights into the factors that motivate parents to use CIFs. Furthermore, it underscores the need for health authorities to improve their communication strategies towards parents concerning new dietary guidelines.

ABSTRACT

Restoring relevant context during consumer sensory testing using virtual reality (VR) technologies may facilitate evaluations reflective of real-world experiences, enabling reliable data collection to better predict product success. Prior research has applied the same consumption scenario to all participants without accounting for variations in individual consumption habits. Thus, a consumption scenario of low personal relevance can lead to misleading conclusions. This study aimed to investigate how personal relevance (usage frequency and similarity) of a consumption environment influences consumer perception and acceptance during product evaluations. Using a VR system, 63 consumers evaluated four commercial frozen chicken nuggets in three virtual environments one week apart: sensory booth, high-relevance kitchen, and low-relevance kitchen. Participants assessed the products virtually on overall liking, Check-All-That-Apply (CATA) on 20 attributes, and purchase intent. They also completed a virtual presence and engagement questionnaire after testing. Results found better product discrimination in both kitchen environments compared to the booth as demonstrated in more post-hoc statistical subgroups (p's < 0.05) on liking and purchase intent. Additionally, more significant product differences were found among CATA attributes in the kitchens. CATA penalty-lift analyses indicated that sensory attributes had more pronounced positive and negative impacts on liking in the high relevance kitchen, followed by the low relevance kitchen, and lastly the booth. Consumers were equally present and engaged during testing across conditions (p's > 0.05). Results suggest providing a personally relevant consumption environment via VR technologies for consumer testing generated more discriminating data that can improve the quality of consumer insights.

ABSTRACT

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.

ABSTRACT

Two firewood species (beech and olive) were used for grilling three meat types (lamb, pork, and veal) to assess their influence on the sensorial properties of meat. A multimethod approach was adopted, including sensory evaluation with consumers and two analytical techniques to characterize the volatile fraction (Solid-Phase Micro-Extraction Gas Chromatography-Mass Spectrometry [SPME-GC/MS] and electronic nose [e-nose]). The sensory session included three pairwise preference tests (one for each type of meat), an overall liking test, a Rate-All-That-Apply test, and a questionnaire on the interest and perceived value of using sustainably certified firewood in food preparation. The firewood species significantly affected the perception of a few crucial attributes. In particular, olive wood increased the roasted meat flavor perception in lamb and veal, while beech wood increased the perceived intensity of a vegetable/herbaceous flavor in veal. No effect of firewood was observed on preference within each pair of meat samples. Lamb was the significantly most liked meat by consumers, followed by pork; veal was the least liked meat type. Positive and negative drivers of preference were discussed. 36 volatile organic compounds were identified from SPME-GC/MS in meats. Congruently with sensory data, the two veal samples showed a greater distance in terms of volatile composition. Relative distances among samples on maps obtained from SPME-GC/MS and the e-nose were similar. This multi-method approach innovatively showed the potential of using firewood as a 'gastronomic' tool to sensorially characterize and valorize cooked meat.

ABSTRACT

BACKGROUND AND AIM: The long-term impact of COVID-19 on nutrition and community health is inevitably noticeable. These effects can change the nutritional behavior and lifestyle of survivors. Due to the COVID consequential fear and anxiety, the pandemic can alter the motivations for choosing, buying, and consuming food. The relationship between nutritional behavior and COVID-19 fear is the primary purpose of this research. MATERIALS & METHODS: This cross-sectional study was conducted via online and face-to-face surveys. Accessing participants was through health centers of Qazvin, Iran, and the selected centers were sampled by cluster sampling method. The study population included 331 adults aged 18 to 65. Data were collected in three sections using valid questionnaires. The Demographic Questionnaire, FCV-19S, and FCQ were used to gather demographic information, the level of fear caused by COVID-19, and food choice motivations, respectively. The statistical analyzes were performed using R software. Analysis of variance and linear regression methods were used to determine the effect of independent variables on dependent variables (p = 0.05). RESULTS: The mean score of fear of COVID-19 in the study population was 15.25 ± 5.78. Price, Mood, Natural content, Familiarity, Convenience, and Ethical concerns were significantly and positively associated with fear of COVID-19 (p<0.05). The only food motive significantly different than before during COVID-19 was Health, which was increased (p = 0.02). Sensory appeal and Health were the most important motivations for food choices before and during COVID-19. The Ethical concern was considered the least important food motivation. DISCUSSION AND CONCLUSION: Some food motivations were associated with fear of COVID-19, possibly due to their psychological nature. The increasing importance of the Health factor and Natural content motivations can relate to the advice of experts on the importance of eating healthy food to counteract COVID-19 and indicate people's preference for this training.

ABSTRACT

The food environment in school neighborhoods plays a crucial role in manipulating the food choices of schoolchildren. This study investigated the relationship between the food environment in neighborhoods and the dietary practices of government school students in a low socioeconomic setting in Sri Lanka. This cross-sectional study surveyed the neighborhood food environment of selected schools (n = 30) in the Monaragala District, Sri Lanka, using geographical information system (GIS) data and collected dietary information from a representative sample of schoolchildren (n = 603). Chi-square and Spearman correlation tests were performed using SPSS version 23.0 to estimate the associations between the food environment and BMI, while ArcGIS 10.4.1 was used to analyze the GIS data. The majority of the students (35.5%) were 15 years old, and approximately 51% were females. The mean BMI of the study participants was 18.14 (±3.28). More than 90% of outlets within proximity sold unhealthy foods. Consumption of confectionaries was 72.3% of the students, whereas healthy food choices ranged from 5% to 12%. A positive correlation between consuming unhealthy food and distance to outlets from school was observed (p<0.05). The risk of consuming low-nutrition food doubled (OR = 2.47, 95% CI: 1.52-3.89) among the students studying in schools where a larger proportion of energy-dense food was sold in closer proximity. In conclusion, the density and proximity of outlets that sell food with low nutrients in the school neighborhood environment were positively associated with students' unhealthy food item choices.

ABSTRACT

BACKGROUND: Acne is an inflammatory disease affecting adolescents during puberty, but also adults. Determinants of acne may include genetic predisposition as well as diet. The Western diet is rich in processed products with low nutrient density, resulting in a lack of supply of many essential minerals that are needed for the body to function properly. OBJECTIVE: The aim of this study was to assess the dietary behaviour of people with acne vulgaris and respondents' selfassessment of the severity of acne lesions after consumption of selected products. MATERIAL AND METHODS: The study was carried out by means of an online, self-administered questionnaire, a link to which was inserted in group of people struggling with acne on a social network. RESULTS: More than half of the respondents said that acne was present in their parents. Almost 91% of the women surveyed said that acne lesions were exacerbated before menstruation. Respondents were most often treated by a dermatologist. The most common foods consumed by the respondents were milk and milk products and wheat bread. The least frequently consumed products were: sultanas, cornflakes, alcohol and fizzy drinks. Statistical analysis showed a strong strength of association between consumption of white rice, fast food, omega-6-rich oils on the severity of acne lesions, while sultana consumption was very strong correlated. In addition, the study showed an almost certain correlation regarding the consumption of white flour pasta on acne lesions. CONCLUSIONS: Statistical analysis showed a relationship between the consumption of white rice, white flour pasta, fast food products, sultanas, oils rich in omega-6 fats and the exacerbation of acne lesions.

ABSTRACT

We examined whether people with high BMI sampled from two different countries were more susceptible to behavioural change via an implicit, rather than explicit, intervention. We measured BMI and used three types of cue interventions (implicit vs explicit healthy lifestyle cue vs neutral cue) to examine their impact on our participants' food choice using the Fake Food Buffet. Healthiness of the meal chosen was measured by the percentage of healthy food items in the meal. Portion size of their chosen meal was operationalised by the total number of food items chosen and its total calorie content was also estimated. Participants were recruited from the United Kingdom (N = 264) and Indonesia (N = 264). Our results indicated that while explicit food cues were overall more effective, implicit cues were a more effective strategy to change food choice behaviours among individuals with high BMI. Participants with high BMI were more likely to regulate the healthiness of their meal and less likely to regulate its portion size or calorie content. The efficacy of our healthy eating interventions was cross-culturally generalizable. Our study supports previous research that implicit cues of a healthy lifestyle might be a more effective behavioural change strategy for individuals with high BMI.

ABSTRACT

In food choices, conflict arises when choosing between a healthy, but less tasty food item and a tasty, but less healthy food item. The underlying assumption is that people trade-off the health and taste properties of food items to reach a decision. To probe this assumption, we presented food items either as colored images (image condition, e.g. photograph of a granola bar) or as pre-matched percentages of taste and health values (text condition, e.g., 20% healthy and 80% tasty). We recorded choices, response times and electroencephalography activity to calculate mid-frontal theta power as a marker of conflict. At the behavioral level, we found higher response times for healthy compared to unhealthy choices, and for difficult compared to easy decisions in both conditions, indicating the experience of a decision conflict. At the neural level, mid-frontal theta power was higher for healthy choices than unhealthy choices and difficult choices compared to easy choices, but only in the image condition. Those results suggest that either conflict type and/or decision strategies differ between the image and text conditions. The present results can be helpful in understanding how dietary decisions can be influenced towards healthier food choices.

ABSTRACT

Adolescents in Germany eat fewer animal products than their parents, often for sustainability reasons. We investigated how adolescents differ from their parents' generation in sustainability food-choice motives, consumption of animal products, and corresponding behaviors such as advocating for and influencing decisions towards more sustainable family meals. In an online questionnaire, an educationally diverse sample of 500 adolescents (M = 17.9 years, range = 15-20) and 500 adults of their parents' generation (M = 52.2 years, range = 45-60) reported food-choice motives, their own and their family's diet style, how they advocate for sustainable food decisions at family meals (e.g., less meat), and how they influence different steps in family meal planning (e.g., grocery shopping). The two generations did not differ in sustainable food motives and mean consumption frequency of meat and animal products, but adolescents reported three times more often than their parents' generation to never eat meat. At shared family meals they advocated for eating plant-based substitutes (d = 0.27, p < 0.001) and other animal products (ß = -0.15, p = 0.02) more often than their parents' generation, but not for eating less meat. Adolescents advocated more frequently for sustainable food decisions at shared meals the more important sustainability motives were to them (ß = 0.53, p < 0.001), and the less meat (ß = -0.35, p < 0.001) and fewer other animal products (ß = -0.11, p = 0.015) they consumed. Adolescents motivated towards sustainability have the potential to impact the family's dietary choices through reverse socialization processes. These findings challenge current theories that suggest only parents influence their children, neglecting the role of adolescents as potential agents of change for improved family and planetary health.

ABSTRACT

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 ∼12 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.

ABSTRACT

Introduction: This cross-sectional study investigated the associations between lifestyle, eating habits, food preferences, consumption patterns, and obesity among female university students in the United Arab Emirates (UAE). Methods: Approximately 4,728 participants, including both Emirati and Non-Emirati students (International Students). Data collection involved face-to-face interviews and anthropometric measurements, showing an interrelated relationship between food preferences and obesity among female university students. Results: While sociodemographic factors and lifestyle habits contribute to obesity, this study uniquely focuses on the role of food preferences and food consumption patterns in body weight status. The findings reveal a significant correlation between the intake of high-sugar beverages-such as milk, juices, soft drinks, and energy drinks-and an increased risk of overweight and obesity among both Emirati and Non-Emirati populations. Notably, milk consumption was particularly associated with obesity in non-Emirati populations (F = 88.1, p < 0.001) and with overweight status in Non-Emiratis (F = 7.73, p < 0.05). The consumption of juices and soft drinks was linked to obesity. Additionally, a significant preference for fruits and vegetables among overweight and obese students was observed, indicating a trend toward healthier food choices. However, there was also a clear preference for high-calorie, low-nutrient foods such as processed meats, sweets, and salty snacks. Fast food items like burgers, fried chicken, fries, pizza, shawarma, chips, and noodles were significantly correlated with increased body weight status, especially shawarma, which showed a notably high correlation with both obesity and overweight statuses (F-values of 38.3 and 91.11, respectively). Conclusion: The study indicated that food choices shape weight-related outcomes is important for designing effective strategies to promote healthier dietary patterns.

ABSTRACT

BACKGROUND/OBJECTIVES: Adherence to dietary recommendations is a critical component in the management of type 1 diabetes (T1D). Taste and flavor significantly influence food choices. The aim of this study was to investigate taste sensitivity and flavor recognition ability in adults with T1D compared to healthy individuals. SUBJECTS/METHODS: Seventy-two people with T1D and 72 matched healthy controls participated in the study. Participants underwent the gustometry test for sweet, sour, salty, and bitter tastes and the flavor test, which consisted of oral administration of aqueous aromatic solutions identifying 21 different compounds. RESULTS: Participants with T1D had significantly lower flavor scores and gustometry scores than controls (p < 0.0001 and p = 0.0063, respectively). T1D individuals showed a lower perception of sour, bitter and salty tastes than controls, while the perception of sweet taste was similar. The sex differences and age-related decline in flavor perception observed in controls were not present in the participants with T1D. Neither BMI nor disease-related parameters such as fasting blood glucose on the day of the study, glycosylated hemoglobin, age at onset of diabetes, duration of diabetes, or type of insulin treatment (insulin pump or multiple daily injections) correlated with flavor and taste perception in the T1D participants. CONCLUSIONS: Flavor and taste perception are impaired in adults with T1D, potentially affecting dietary adherence and food choices. This highlights the need for further research into the mechanisms underlying sensory changes in T1D and emphasizes the importance of targeted dietary interventions to improve health outcomes and quality of life in this population.

ABSTRACT

OBJECTIVE: Bariatric surgery reduces sweet-liking, but mechanisms remain unclear. We examined related brain responses. METHODS: A total of 24 nondiabetic bariatric surgery and 21 control participants with normal weight to overweight were recruited for an observational controlled cohort study. They underwent sucrose taste testing outside the scanner followed by stimulation with 0.40M and 0.10M sucrose compared with water during functional magnetic resonance imaging. A total of 21 bariatric participants repeated these procedures after surgery. RESULTS: Perceived sweet intensity was not different among the control, presurgery, or postsurgery groups. Bariatric participants' preferred sweet concentration decreased after surgery (0.52M to 0.29M; p = 0.008). Brain reward system (ventral tegmental area, ventral striatum, and orbitofrontal cortex) region of interest analysis showed that 0.40M sucrose activation  (but not 0.10M) decreased after surgery. Sensory region (primary somatosensory and primary taste cortex) 0.40M sucrose activation was unchanged by surgery and did not differ between control and bariatric participants. Primary taste cortex activation to 0.10M sucrose solution was greater in postsurgical bariatric participants compared with control participants. CONCLUSIONS: Bariatric surgery reduces the reward system response to sweet taste in women with obesity without affecting activity in sensory regions, which is consistent with reduced drive to consume sweet foods.

ABSTRACT

The perception of the ambiguous image of #TheDress may be influenced by optical factors, such as macular pigments. Their accumulation during childhood could increase with age and the ingestion of carotenoid-containing foods. The purpose of this study was to investigate whether the visual perception of the dress in children would differ based on age and carotenoid preference. This was a cross-sectional, observational, and comparative study. A poll was administered to children aged 2 to 10 years. Parents were instructed to inquire about the color of #TheDress from their children. A carotenoid preference survey was also completed. A total of 413 poll responses were analyzed. Responses were categorized based on the perceived color of the dress: blue/black (BB) (n = 204) and white/gold (WG) (n = 209). The mean and median age of the WG group was higher than the BB group (mean 6.1, median 6.0 years, standard deviation [SD] 2.2; mean 5.5, median 5.0 years, SD 2.3; p = 0.007). Spearman correlation between age and group was 0.133 (p = 0.007). Green-leaf preference (GLP) showed a statistically significant difference between groups (Mann-Whitney U: p = 0.038). Spearman correlation between GLP and group was 0.102 (p = 0.037). Logistic regression for the perception of the dress as WG indicated that age and GLP were significant predictors (age: B weight 0.109, p = 0.012, odds ratio: 1.115; GLP: B weight 0.317, p = 0.033, odds ratio: 1.373). Older children and those with a higher GLP were more likely to perceive #TheDress as WG. These results suggest a potential relationship with the gradual accumulation of macular pigments throughout a child's lifetime.

ABSTRACT

Introduction: British Muslim School Children (BMSC) are required to follow special halal dietary requirements in accordance with their religion, which is often not accounted for in British schools. This often leaves BMSC limited to a vegetarian diet while at school, despite this not being their chosen diet or preference. This study explores the perceptions of key stakeholders regarding fairness and accessibility of school meals for BMSC, as well as discussing school food provision for those maintaining a religious diet in light of social justice. This is in the context of limited knowledge previously being explored in the North East of England regarding procurement and decision-making at a systems level to cater for BMSC. Methods: A qualitative research design was conducted. A total of 62 participants (39 BMSC, 15 parents, and 8 school and catering staff) took part in a semi-structured interview or focus group. Participants were recruited from six schools, with these schools selected based on their differing levels of BMSC in attendance. This project took place between March 2022 and October 2023. Results/discussion: Results suggested that where schools already catered for diverse food requirements, inclusive of BMSC dietary needs, food choices were still limited in the options and amount available. School and catering staff stated that cost implications contributed to their menu development process. Despite this, there was an evident willingness to learn about the cultural food options and how these can be implemented in future school menus. Suggestions discussed included an increase in the use of halal meat in order to provide a more inclusive school food experience for BMSC.

ABSTRACT

INTRODUCTION: College campuses provide an expansive food environment, which may contribute to elevated risk of excess energy intake and weight gain among college students. All-you-can-eat style cafeterias often expose students to hyper-palatable foods (HPF), which may promote overeating. This study aimed to examine the availability of HPF in an all-you-can-eat college cafeteria, and to examine HPF intake during meals among undergraduates. METHOD: Publicly available cafeteria menu data from a Midwestern university were analyzed and included 25 meals. To determine the availability of HPF within the cafeteria meals, the standardized definition of HPF by Fazzino et al. (2019) was used, which specifies combinations of palatability-inducing nutrients at quantitative thresholds that may induce hyper-palatability. Participants (N = 225) who ate in the cafeteria in the past 24 h were presented with a list of all menu items for their corresponding cafeteria meal, and self-reported all items consumed. RESULTS: On average, 40 % (SD = 1.4) of total food items available per meal were HPF, with 68 % (SD = 3.6) of items with elevated fat and sodium. Regarding intake of HPF among students, approximately 64 % (SD = 31.4) of foods consumed were HPF, and 51 % (SD = 32.3) of items consumed had elevated fat and sodium. CONCLUSION: Findings indicated that college students may be regularly exposed to HPF in all-you-can-eat college cafeteria environments, and that students may consume cafeteria meals that are primarily comprised of HPF.
