Research Purpose:
The objective of this study was to test the 3 dietary patterns,as presented by the USDG, among AA adults at risk of T2DM. In this 12-wk intervention, we hypothesized that participants assigned to the Mediterranean and Vegetarian patterns (both diets have an emphasis on plant-based foods) would have greaterimprovements in body weight, HbA1c, blood pressure (BP), anddietary quality (HEI score) than participants assigned to thehealthy US-style dietary pattern.
