Home-Delivered DASH Diet Grocery Program for Adults with High Blood Pressure in Florida, Georgia, and Tennessee

What this Trial Is About

Researchers are evaluating a home-delivered, dietitian-assisted grocery intervention based on the DASH diet to help adults with high blood pressure in Florida, Georgia, and Tennessee. The study aims to determine if this approach can lower blood pressure by providing groceries aligned with the DASH dietary pattern, which is known to reduce hypertension, a major risk factor for cardiovascular diseases and death. Participants will be randomly assigned to one of two 4-week interventions. One group will receive weekly home deliveries of DASH-patterned groceries ordered with the help of a dietitian via a virtual supermarket, with groceries tailored to their calorie needs and family size. The other group will receive a monthly stipend and a DASH diet brochure to support self-directed grocery shopping without restrictions on food choices. During the study, participants will measure their own systolic blood pressure before and after the 4-week intervention. Other assessments include technician-measured blood pressure, body mass index, dietary recalls, urine sodiumpotassium ratio, lipid levels, fasting glucose, and serum potassium. Researchers will monitor adherence through virtual counseling and educational content at food delivery. The study will last a total of 4 weeks per participant, focusing on changes in blood pressure and other health markers.
