The Bionutrition Unit offers a variety of services to investigators in nutrition-related research. Dietitians are available to help plan, design, and implement the nutritional components of research protocols; recruit and screen research participants; and collect and analyze dietary intake data. Our Metabolic Kitchen’s research cooks are experts in preparing research meals.

For those who are in the planning stages of a research project, we offer a free walk-in clinic from 11:30am-1pm on the first Wednesday of every month (for more information, see the CCTS Events page).
