NCT ID: NCT06324630 Not yet recruiting - Food Habits Clinical Trials

Implementation of Innovative Food Prescription Programs in Older Adults

Start date: March 2024
Phase: N/A
Study type: Interventional

In the USA, about 10% of grown-ups have a hard time finding healthy food, like fruits and vegetables. It's even harder for older grown-ups who might be sick and find it tricky to move around, which makes it tough to get healthy food. The investigators are trying to fix this by testing two new ways to help older people (aged 65 and up) get nutritious food. The investigators are getting lots of help and ideas from older adults to make these ways work the best they can. The study is happening at the Erie County Medical Center (ECMC) in the East Side of Buffalo, NY, where many African Americans live. This place hasn't been treated fairly, so there aren't many places to buy fresh fruits and vegetables in the local stores. On the ECMC campus, there are three clinics that can help people who can't easily get healthy food. Every participant in our study will be put into one of three programs, each lasting 12 weeks, and they will get food every week. In the "usual care" program, a doctor writes an order, and the participant gets a voucher to buy more fruits and vegetables at a market or store. In the "delivery of a produce prescription box" program, a box of fruits and vegetables is brought to the participant's home. The participant can pick what they like online or by calling a helper. If they don't pick, they get a regular box. In the "delivery of a meal kit box" program, the participant gets the ingredients for three meals in a box. The participant can pick three meals they like online or by calling. If the participant doesn't pick, three meals will be chosen for the participant. For the second and third programs, participants will get messages to remind the participant when to choose their food, when the time to choose is almost up, and when their food is on its way. If a participant can't use messages or the internet, they can call a helper for support. The investigators believe the study will show that these ways can help older adults who have a hard time getting food to eat more fruits and vegetables. The investigators will also find out which way works best compared to the usual way in the Buffalo, NY area.

NCT ID: NCT06263621 Active, not recruiting - Obesity Clinical Trials

Changing Portion Size Descriptions in a Cafeteria

Start date: January 11, 2024
Phase: N/A
Study type: Interventional

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.

Visceral Adiposity, Vagal Tone and Food Preferences: a Pilot Study

ObVague
Start date: December 11, 2023
Phase:
Study type: Observational

Food preferences are defined by a number of measurable parameters, such as per se food choices, sensitivity of taste and olfactory sensory perceptions, hedonic appreciation of foods ("liking") and motivation to consume them ("wanting"). These food preferences are fundamental to the quality of food intake, and are therefore a key factor influencing weight loss or maintenance of a stable weight. Obesity is also associated with reduced sensory sensitivity to taste and smell, as well as disturbances in the responses of the food reward system. However, the internal, or physiological, mechanisms impacting these food preferences are still poorly understood. To date, several studies seem to point to the role of body composition, in particular visceral adiposity, or adiposity surrounding the digestive organs. Indeed, a high level of visceral adiposity is associated with the onset of numerous cardiometabolic disorders, but also with altered sensory perceptions. This relationship could be mediated by the vagus nerve, which connects the digestive organs to the brain, enabling the perception of internal signals sent by the body, such as feelings of hunger or satiety. Low vagal activity is associated not only with abdominal obesity, but also with reduced sensory sensitivity to taste and smell, and changes in food choices in favor of energy-dense foods (rich in fats and/or sugars). Electrical stimulation of the vagus nerve is now recognized as a possible treatment for morbid obesity in the USA, but the mechanisms leading to the expected weight loss are still debated. Similarly, an increase in vagal tone has been found in patients who have undergone bariatric surgery for the treatment of severe complicated to morbid obesity, in parallel with sensory disturbances. The overall aim of this project is to explore and confirm the relationship between visceral adiposity and various food preference parameters, such as olfactory and gustatory perceptions and reward system responses, involving liking and wanting certain foods and associated behaviors. This project also aims to shed light on the possible mediation of the vagus nerve in this relationship.

NCT ID: NCT06090409 Recruiting - Dietary Habits Clinical Trials

Encouraging a Plant Based Diet in an Underserved Urban Population

Phase: N/A
Study type: Interventional

The investigator's goal is to promote a plant-based diet amongst the underserved urban population of Louisville with the help of educational aids and the provision of affordable resources.

NCT ID: NCT06015490 Recruiting - Appetitive Behavior Clinical Trials

The Impact of the Physiological Response to Sugar on Brain Activity and Behavior

Start date: September 1, 2023
Phase: N/A
Study type: Interventional

The goal of this pilot study is to test the feasibility of assessing how biological factors and chemical properties of sugars may influence metabolism and food reward in humans. The main questions it aims to answer are: - Can differences in appetitive responses and neural activations to sucrose (table sugar) and its chemical components (glucose and fructose) be measured and quantified? - Are there detectable differences in how combinations of sugars and non-nutritive sweeteners commonly found in our food supply influence appetitive responses and neural activation? This study is a crossover design, meaning every participant will complete every condition. Participants will consume beverages containing sucrose, glucose, or fructose, which are each novelly flavored, 6 times within a week. During one of the consumption times, energy expenditure, carbohydrate oxidation, and blood glucose will be measured in the lab before and for 2 hours after consumption. After participants have consumed each condition, they will undergo a tasting task in the MRI scanner, neural responses to receipt of the beverages are measured. Another group of participants will undergo the same study design but with sucrose, high fructose corn syrup, or sucrose + non-nutritive sweetener as the conditions.

NCT ID: NCT05977348 Recruiting - Obesity, Childhood Clinical Trials

Increasing Food Literacy in Preschoolers to Reduce Obesity Risk

Start date: October 3, 2023
Phase: N/A
Study type: Interventional

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.

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.

NCT ID: NCT05825963 Completed - Obesity Clinical Trials

Psyllium-enriched Hamburger Meatballs: Effects on Postprandial Lipidemia, Glycemia, Appetite, and Food Intake

Start date: April 12, 2022
Phase: N/A
Study type: Interventional

The goal of this clinical trial is to enrich the hamburger meatball with psyllium without impairing its sensory properties and to investigate the effects on acute postprandial lipemia and glycemia, prospective food intake, and some appetite indicators in healthy adults. The main hypotheses of the study are: 1. There is no difference in sensory analysis results between hamburger meatballs enriched with psyllium and those that are not enriched. 2. The rise in postprandial lipids after consuming psyllium-enriched hamburger meatballs is lower than that of classic hamburgers. 3. The rise in postprandial glycemia after consuming psyllium-enriched hamburger meatballs is lower than that of classic hamburgers. 4. The feeling of satiety after consuming psyllium-enriched hamburger meatballs lasts longer, and the feeling of hunger lasts for a shorter period compared to classic hamburgers. 5. Daily food intake after consuming psyllium-enriched hamburger meatballs is less than that of classic hamburgers. Participants will, - Eat hamburgers, after fasting for 12 hours, with psyllium-enriched and classic meatballs on intervention days. - Keep a record of their food intake for the previous and following 24 hours of each intervention. - Be given fasting and postprandial blood samples. - Evaluate their hunger and satiety levels on a 100 mm horizontal visual analog scale (VAS) at the beginning and every hour for the following 6 hours of the study.
