Filter by:The overall objective of this research is to evaluate the impact of gamification on the diet quality of food choices made by American adults in an online grocery shopping experiment. Participants will shop for 12 food items from a grocery shopping list determined by the research team in a simulated online grocery store designed for this experiment. Each product has a nutritional quality score based on the Guiding Stars algorithm. The experiment tests the gamification of the nutritional quality score. Participants exposed to gamification see one to five crowns illustrating the nutritional quality of the food and a scoreboard indicating the total number of crowns from foods in the participant's shopping basket. Participants will be assigned to experimental conditions of gamification (game or no game) and a fictitious budget ($30 or $50). The investigators will test if the game and the budget affect the dietary quality of their final shopping baskets. The experiment is a 2x2 experimental design. The investigators hypothesize that the presence of gamification will change the dietary quality of participants' final shopping baskets. The investigators hypothesize that a higher budget will change the dietary quality of the final shopping basket. The investigators also hypothesize that the game and higher budget together will change the dietary quality of the final shopping basket.
This study aims to investigate whether consumers differ in mouthdrying sensitivity and if mouthdrying can be modulated.
Obesity is currently one of the most substantial health burdens. Due to the production of marked and sustained weight loss, bariatric surgery is an increasingly used therapeutic modality to combat obesity and its comorbidities. Surgical rearrangement of the gastrointestinal tract remarkably alters metabolism and hormones acting on neurological and hypothalamic signalling involved in food decision-making and eating behaviour. In this context, many patients who underwent bariatric surgery self-report changes in appetite, satiety and food preferences. Furthermore, new gut hormone-based (e.g. GLP1-receptor agonist or GLP-1-RA) pharmacotherapies which mimic the effect of bariatric surgery show impressive efficacy on weight reduction by modulation of food behaviour. However, the mechanisms of such functional changes, and how they relate to food decision-making remain unknown. In this project, the investigators propose a novel approach to unravel the effect of obesity treatments (surgical and non-surgical) on the neural coding of nutritional attributes and its impact on dietary choices using a combination of brain imaging, computational modelling of food behaviour and assessment of eating and food purchase behaviour in daily life.
Direct measurements of changes in food selection in humans after RYGB have been limited by the unreliability of patients, which poses significant methodological and conceptual challenges to researchers and study design. Self-monitoring requires time and effort, and many find tracking of dietary intake tedious, which contributes to attrition. Direct measurements, however, represent an essential component in the attempt to understand how RYGB alters eating and food preferences, but laboratory settings preclude a real-life environment. The aim of this study is to investigate changes in food preferences, total energy intake of the three primary macronutrients and meal patterns between obese women (BMI ≥ 35) before and after Roux-en-Y gastric bypass and lean (BMI ≤ 25) and obese (BMI ≥ 35) controls by means of photographic food recognition with a mobile application.
Nutrition supplements have tremendous impact upon the nutritional and developmental status of malnourished children. These products have been designed to be acceptable to children (often by adding nutritive sweeteners to make them more palatable), but to date there has been little rigorous testing of their palatability for infants, toddlers and young children. The overall goal of this project is to investigate whether: 1. children's acceptance of a nutrition supplement is associated with maternal persistence in offering the food to her child over a 2-week period; 2. an unsweetened version of the nutrition supplement differs in short- and long-term acceptance; and 3. maternal liking of the supplement is associated with her persistence in offering the food to her child.
Brief Summary: This study aims to investigate whether protein fortification of beverages causes mouthdrying and mucoadhesion and whether this is influenced by saliva flow.

Blue dishware was alternated with white dishware for lunch and dinner for residents living with dementia. Food consumption occurred in the home dining room and food was weighed before and after consumption to determine proportion consumed. Eating challenges were also noted. Within-participant comparisons were made to determine if food intake and eating challenges improved with the blue dishware condition.
Sugar-sweetened beverages are a significant contributor to adult and childhood obesity in Guatemala. Policies to place health warning labels on sugar-sweetened beverages are being pursued, but there is little empirical data on how such labels influence people. The primary aim of this study is to test the association between sugar-sweetened beverage (SSB) warning posters compared to control posters and change in SSBs purchased compared to baseline by adolescents shopping at school cafeterias in Guatemala City, Guatemala. The hypothesis is that posters with information warning people of the health harms associated with overconsuming SSBs and promoting low sugar beverages will be associated with greater reductions in SSB purchases compared to a control poster.
Obesity, unhealthy dietary habits, and food insecurity are major public health concerns, especially affecting individuals living in poverty. Food pantries, which provide free food to those in need, are increasingly interested in promoting healthy choices, but few rigorous studies have tested healthy eating interventions in food pantry settings. The overall objective of this proposal is to conduct a randomized-controlled trial among 500 regular food pantry clients to compare the influence of a behavioral economic intervention to promote healthier food choices delivered via a web-based ordering platform to usual care (control group).
