Groceries Plus Multi-Component Lifestyle Intervention for Adults With Hypertension and Type 2 Diabetes

Description

People with high blood pressure and diabetes often have low levels of key nutrients as a result of not eating enough fresh fruits and vegetables. Research studies suggest that these nutrients can lower blood pressure and blood sugar. This study will investigate if providing encouragement to adopt this healthy and nutritious way of eating and providing guidance on weight management will lower blood pressure and blood sugar. The DASH-Life research study will recruit adults with hypertension and type 2 diabetes who live in Baltimore metro areas that don't have many stores selling healthy foods. The DASH-Life research study is 6 months long. Participants will be randomly assigned to one of two groups: 1) Self-Shopping DASH (S-DASH) diet advice group, or 2) Coaching DASH (C-DASH) diet advice group.
