Can soul food makeover cut diabetes risk? new study tests culturally relevant diets
NCT ID NCT05254496
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether three culturally tailored diet patterns (U.S.-style, Mediterranean, and vegetarian) can improve eating habits and reduce type 2 diabetes risk in 198 African American adults. Participants attend weekly classes for 6 months, then bi-weekly for another 6 months. The goal is to see if making diets more relevant to African American culture leads to better health outcomes.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- dietary intervention classes (Healthy U.S.-Style, Mediterranean-Style, or Vegetarian Eating Pattern)
- What this could lead to
- If successful, this could show that culturally relevant dietary guidelines help African Americans eat healthier and lower their risk of type 2 diabetes.
- What could go wrong
- This is a behavioral study, not a drug trial, so results depend on participants sticking to the diet. It is also relatively small and may not apply to all African Americans.
