The eating plan known as Dietary Approaches to Stop Hypertension (DASH) is used to lower or control high blood pressure. The DASH diet contains foods that are lower in sodium. A key goal is to include foods that are rich in nutrients that are also associated with lowering blood pressure — potassium, magnesium and calcium. The DASH diet features menus with plenty of vegetables, fruits and low-fat dairy products, as well as whole grains, fish, poultry and nuts. It offers limited portions of red meats, sweets and sugary beverages.
