ENSURING THE CULTURAL RELEVANCE OF DIETARY GUIDELINES DIET PATTERNS AMONG AFRICAN AMERICANS: INCREASING DIETARY QUALITY AND REDUCING TYPE 2 DIABETES RISK

FUNDING SOURCE: NIDDK, 2021-2026

PRINCIPAL INVESTIGATOR: Brie Turner-McGrievy, PhD, RD

CO-INVESTIGATORS:

Currently, US adults are falling short of the nutrition recommendations (fruit/vegetable intake, greens/beans, whole grains, etc.) set forth by the United States Dietary Guidelines (USDG). Using a community-based design, the research team will recruit African American adult participants with overweight/obesity and more than three risk factors for type 2 diabetes to conduct a three-part study. The first phase will examine the adoption of the three dietary patterns (i.e., Healthy U.S.-Style, Healthy Mediterranean-Style, Healthy Vegetarian) during a three-month randomized trial, using materials as presented by the USDG. The next two phases will incorporate feedback from participants to culturally-adapt USDG materials, and test a refined, culturally tailored one-year intervention examining the three diet patterns and differences in healthy eating patterns and risk factors for type 2 diabetes among participants.
