Clinical Trial Summary

The role of diet in preventing hypertension and cardiovascular diseases in African Americans, who have a much higher risk of developing these diseases, is not well understood. Therefore, this project will investigate whether African Americans following a 100% plant-based diet have more optimal blood pressure, vascular function, and blood lipid profiles, along with lower systemic inflammation relative to African Americans following a typical American diet.

Intervention

Other:
• Typical American Diet
Participants self-reported adherence to a typical American diet prior to enrolling in the study. This factor determined cross-sectional group allocation.
• Plant-Based Diet
Participants self-reported adherence to a 100% plant-based diet prior to enrolling in the study. This factor determined cross-sectional group allocation.
