Scientists supported by the National Heart, Lung, and Blood
Institute (NHLBI) conducted two key studies. Their findings
showed that blood pressures were reduced with an eating plan that
is low in saturated fat, cholesterol, and total fat and that emphasizes
fruits, vegetables, and fat-free or low-fat milk and milk products.
This eating plan—known as the DASH eating plan—also includes
whole grain products, fish, poultry, and nuts. It is reduced in lean
red meat, sweets, added sugars, and sugar-containing beverages
compared to the typical American diet. It is rich in potassium,
magnesium, and calcium, as well as protein and fiber. (See box 2
for the DASH studies’ daily nutrient goals.)
