During a 7-day run-in phase, participants will first consume a control diet similar in nutrient composition to the control diet of previous DASH studies. The control diet, which is a diet typical of most Americans, is reduced in servings of fruits, vegetables, low fat dairy products and relatively high in total and saturated fat. Immediately following the run-in phase, participants will receive the DASH diet during a 14-day intervention phase. Both diets will have the same sodium content and caloric intake will be adjusted for each participant to keep weight stable. All study meals and snacks will be provided.
