35 Clinical Trials for Various Conditions
This is a randomized trial to examine the influence of number of "likes"on social media food ads on Black and White adolescents' food purchases
The primary objective of this study is to test the relative effects of climate-impact menu label designs on the healthfulness of consumers' fast-food meal choices. Participants will complete hypothetical online meal ordering tasks using a survey which emulates the online menus of two types of fast-food chain restaurants: a burger restaurant and a sandwich restaurant. Participants will be randomized the view both menus, presented in random order, with one of five labeling conditions applied. Secondary objectives include examining total greenhouse gas emissions per meal order, energy and nutrient content of meals ordered, prices of meals ordered, and, through a post-order survey, noticeability, and perceptions, and knowledge and understanding of labels between the conditions.

The aim of this study is to compare responses to 6 different types of labels for restaurant menus: 1) a QR code on all items (control); 2) High Climate Impact label; 3) High Climate Impact Warning label; 4) Climate Grade label; 5) Climate Grade label also displaying full range of possible grades; 6) Estimated Environmental Cost label. Participants will be randomized to 1 of these 6 labeling arms. Each participant will view a menu based on a real-world restaurant with one of the 6 labels shown on applicable menu items, select the menu item they would like, and then respond to survey questions about each label.
The study aims to determine whether viewing health or climate labels (or both) and receiving recommendations for healthier or more climate-friendly swaps (or both) in an online grocery store environment improves the healthfulness and reduces the carbon footprint of consumers' food and beverage purchases compared to shopping as usual without swap recommendations. The online store will record participants' food selections. Participants will also be asked to complete survey measures.
This project is the first stage of a health promotion campaign to shift social norms about marketing and feeding children ultra-processed foods. Embedded within a longitudinal ethnographic study using photo-elicitation techniques, mothers of preschool-age children will be randomly assigned to arts-based or traditional education about ultra-processed food.
The goal of this this intervention is to test the degree to which a portion size labeling intervention influences consumer selection of smaller portions at two large cafés. The main question it aims to answer is: Do consumers order fewer calories when the portion size label for the smaller entree is called "standard" instead of "small"? Participants will order lunch as usual in the two cafes (one intervention, one control) for 5.5 months, and all order items will be recorded in the check-out system. One cafe will receive the labeling intervention, while the other will not. Researchers will compare the average calories per order between the two cafes to see if there are differences.
The aim of this study is to examine emerging adults' responses to dietary substitution messages about health, the environment, or both health and the environment.
The study will include women enrolled during the second trimester of pregnancy who will be provided with a specific amount per month for 10 months to purchase produce. Women will be provided with up to three nutrition education sessions and will be sent text message reminders to redeem their incentives every month and to provide them with nutrition tips. The study will use a co-design approach to utilize feedback from potential participants as well as participants at multiple time points in the process to improve the intervention and make it more relevant and impactful to our population.
This study tests the effect of two climate change menu labels, one indicating 'low climate impact' and the other indicating 'high climate impact' on ordering choices and perceptions of healthfulness of food ordered in an online randomized experiment.
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 is a pilot evaluation of the Healthy Pantry Program, a new behavioral economics-based training that allows pantry staff to learn how to implement nudges integrating traffic-light nutrition labeling and a healthy recipe database in the pantry environment. The hypothesis is that participation the Healthy Pantry Program will lead to increases in pantry purchases of healthy foods.
Food insecurity is associated with an increased risk of obesity. The availability of a default option (i.e., option a consumer selects if no active choice is made) has been shown to effectively nudge consumer behavior. An online default option (i.e., prefilled grocery shopping cart) was previously shown to positively impact the food purchases of individuals with food insecurity.The present study aims to extend these findings bye examining efficacy of an online default option in enhancing the nutritional quality of online grocery purchases in individuals with food insecurity over the course of a month.
The investigator proposes an evaluation of a randomized, sustainable intervention in 8 intervention and 8 control pantries. We will enroll a sample clients at the food pantry at baseline and follow them for 1 year to assess changes in overall diet quality (the primary outcome) and cardiovascular health. We will also enroll a sample of clients at follow-up to assess to assess the nutritional quality of food selected at the pantry.
Most studies on menu labels have been conducted in mostly non-Hispanic white individuals, and how menu labels affect calories and macronutrients ordered in Hispanics is not clearly understood. This study evaluated the impact of menu labels on calories and macronutrients ordered in Hispanics.
The goal of this study is to determine subjective gastrointestinal tolerance response and differences in breath hydrogen response following the consumption of different types of low FODMAP oral nutrition supplements. This randomized, crossover study requires participants to arrive to the lab 12 hours fasted, consume an oral liquid supplement and complete gastrointestinal tolerance questionnaires as well as produce samples for breath hydrogen analysis at various time points over a 4 hour time period.
The goal of this study is to determine subjective gastrointestinal tolerance response and differences in breath hydrogen response following the consumption of two types of juice. This double-blind crossover study requires participants to arrive to the lab 12 hours fasted, consume 12 oz of juice and complete gastrointestinal tolerance questionnaires as well as produce samples for breath hydrogen analysis at various time points over the next 3 hours. Subjects will be asked to complete additional questionnaires at 12 and 24 hours post consumption, from home. Subjects will also be asked to keep a food record for 24 hours prior to their scheduled visit times to assure compliance.
The satiety effects of pulses compared to a matched smoothie will be measured.
The satiety effects of the combination of protein and fiber within egg and whole grain breakfast meals. High protein with low and high-fiber is hypothesized to be more satiating than low protein, low fiber.
The satiety effects of beef will be compared to beans. Beef is hypothesized to be more satiating than beans.
The combination of fiber and protein added to pasta will enhance satiety.
The investigators hypothesize that consumption of either white or brown rice will be more satiating than glucose control.
Research suggests dietary fiber may decrease transit time through the gastrointestinal tract. Research studies traditionally use radio-opaque markers to determine gastric emptying, colonic transit, and whole gut transit time. The SmartPill is a single use pill that can be used to determine gastric emptying, colonic transit, and whole gut transit time without requiring X-rays or fecal collections. Previous studies have found radio-opaque markers and the SmartPill detect the similar transit times. The purpose of this pilot study is to determine if the SmartPill can detect a change in transit time using a significant dose of dietary fiber.
In recent years, GLP-1 medications have become a widely employed approach by physicians to address weight concerns in patients and lead to weight loss. Little is known, however, about how these medications may alter an individual's attitude towards food, food reactivity, or the specific types and amounts of foods an individual will choose. The purpose of this study is to observe the changes an individual experiences in their relationship and reaction to food and in their food selection prior to or within the first two weeks of taking GLP-1 medication to after three months on the medication. The researchers of this study believe that an understanding of such changes can inform questions seeking to ensure maintenance of appropriate nutrient balance within individuals on weight loss medications.
The goal of this observational study is to develop an adaptable mobile produce market model to be used on college campuses to increase college students' access to fresh fruits and vegetables. Food insecurity on college campuses threatens academic success and student well-being, and affects first generation, lower-income, and racial/ethnic minority students at higher rates. This research will include a pilot campus mobile market operated on the University at Buffalo campus. The main questions it aims to answer are: 1.) What makes it hard for students to eat healthy foods on the University at Buffalo campus, 2.) How does a mobile market need to operate on a college campus to best reach students, and 3.) What is the relationship between mobile market use and changes in how many fruits and vegetables students eat, students' ability to consistently eat foods that promote health and well-being, and participation in the Special Nutrition Assistance Program (SNAP).
The goal of this study is to determine whether eco-labels denoting more sustainable menu items improve the healthfulness of participants' entrée and appetizer selections from a restaurant menu. US adults will complete a restaurant ordering task in which they will select menu items to order from a mock restaurant menu modeled after a popular US sit-down restaurant. Participants will be randomized to a restaurant menu with or without eco-labels denoting more sustainable menu items. The investigators will record participants' selections from the menu. Participants will also answer survey questions.
The goal of this study is to determine whether certain front-of-package food labeling systems improve the healthfulness of consumers' grocery selections. US adults who are their households' primary shoppers will complete a shopping task in a naturalistic online grocery store. They will be exposed to different front-of-package food labeling systems and asked to shop for groceries. The online store will record participants' selections. Participants will also be asked to complete survey measures.
The goal of this clinical trial is to examine the effects of a nutrition education program on preschool children's food literacy and food acceptance, and to examine the added influence of a healthy eating curriculum and parent education on children's food knowledge and healthful food choices. The project will be evaluated with 450 children ages 3 to 5 years in center-based childcare programs serving predominantly Supplemental Nutrition Assistance Program (SNAP)-eligible families in Pennsylvania. Outcomes for children who receive the added healthy eating curriculum will be compared to children in classrooms that only receive the nutrition education program.
To assess feasibility and acceptability of of integrating Food Rx and Best Feeding Practices with EFNEP participants via a pilot study.
The goal of this study is to uncover sleep and circadian mechanisms contributing to adverse metabolic health. The protocol is a 21 day (7 outpatient days, 14 inpatient days) mechanistic randomized-crossover study designed to identify the impact of chronic sleep restriction and circadian timing, independently and in combination on energy metabolism and identify the independent and combined effects on glucose tolerance.
