The DASH diet emphasizes fruits, vegetables, and low-fat dairy products; includes whole grains, poultry, fish, and nuts; and is reduced in red meat, sweets, and sugar-containing beverages. Intervention Phase: This intervention is a weekly, 4-week DASH dietary intervention. A dietitian will assist participants in ordering groceries in a pattern consistent with the DASH diet to be delivered to their homes. The quantity of groceries will be based on participant Calorie needs and family size.
