The DASH diet is a flexible and balanced eating plan that helps create a heart-healthy eating style for life. It includes foods that are rich in potassium, calcium and magnesium, and limits foods that are high in sodium, saturated fat and added sugars. Studies have shown that the DASH diet can lower blood pressure and LDL cholesterol levels in as little as two weeks. The diet is rich in vegetables, fruits and whole grains, and includes fat-free or low-fat dairy products, fish, poultry, beans and nuts. To reduce sodium, it is important to use sodium-free spices or flavorings instead of salt, not add salt when cooking rice, pasta or hot cereal, and choosing plain fresh, frozen or canned vegetables.
