Randomized Trial of Tailored Dietary Advice to Lower Blood Pressure

The Five Plus Nuts \& Beans Study is a randomized, controlled trial to compare two strategies for translating the results of the DASH (Dietary Approaches to Stop Hypertension) Study into practice for 120 African American participants who are on stable doses of antihypertensive medications. The first arm of our study offers minimal DASH-oriented dietary advice along with a food credit at a local supermarket where they make their own decision of what to eat. The second arm consists of a single one-hour session with a nutrition expert who provides choices and places an on-line order from a community grocery store (Santoni's Market) with targeted purchases of fruits, vegetables, nuts and beans. Our primary outcome is change in blood pressure at 8 weeks. Secondary outcomes are effects on glucose, uric acid, urine potassium excretion, and self-report consumption of fruits and vegetables during the same period.
