Fuel for Thought: How do sugar and fat affect each other in the brain? Do you ever wonder what happens in your brain when you eat dessert? And why sugary and fatty foods are so appealing? If so, you may eligible to participate in a research study to understand the impact of sugar and fat on the brain!

The purpose of this study is to investigate age effects on foot-ankle mechanical power interactions in walking and their underlying mechanisms to improve walking performance and economy in older adults.

We are trying to understand responses to food labels among adults who identify as Hispanic/Latino.

Did you know that over 250 million persons are affected by Osteoarthritis? It is the leading cause of disability among adults and has no cure. Prevention of OA is preferable to treatment and females are affected at nearly twice the rate as males. If you are a female, at least 50 years of age, overweight, with no or occasional knee pain, you may be able to participate in a research study to find out if a diet and exercise program or a health education program prevent knee OA.

If you are healthy and between the ages of 18-55 years, you may be eligible to participate in a research study to find out how sugar affects the brain of individuals who carry certain genetic variants.

Are you scheduled for weight loss surgery within the next 12 months? You may be able to take part in a research study to help us learn more about your metabolic hormones, eating behaviors, stress, and weight loss before and after your surgery.

In this study, we want to learn more about two strategies that interrupt sitting: walking and seated pedaling. Sitting, or sedentary behavior, is a public health crisis that increases all causes of mortality and doubles the risk of cardiovascular disease. Interrupting sitting may help reduce the cardiovascular disease risk associated with uninterrupted bouts of sitting.

Nutrition is not one-size-fits-all. Nutrition, or the foods we eat, can help prevent and fight conditions such as high blood pressure, diabetes, stroke, and more. However, we all live in different environments, we come from different cultures, and each of us is starting from a different place with our health. Additionally, everyone breaks down food differently. Join the Nutrition for Precision Health research study to help researchers learn how our genes, cultural backgrounds, and environments affect our bodies' responses to food. Compensation provided.

During puberty, adolescents grow and change a lot which may make life seem more stressful and emotional. Male and female adolescents experience the changes associated with puberty differently, possibly because of different responses to changes in hormones, including testosterone and estrogen. We are interested in learning more about the role of these hormones in regulating emotional processing and mood symptoms, and whether a mobile training program can help improve mood during the pubertal transition. Participation is 8 weeks with two monthly follow-up surveys. Compensation provided.

We want to learn how people's brains adapt when responding to various food stimuli and decision-making processes. We also want to learn about brain responses to food and beverage consumption. To do this, we will use taste tests, surveys, behavioral tasks, and neuroimaging (fMRI scan).
