APA Dictionary of Psychology

a dietary plan developed, tested, and promoted by the National Heart, Lung, and Blood Institute with the specific goal of lowering high blood pressure. It works by limiting foods containing elements known to raise blood pressure, such as sodium and cholesterol, and by including foods containing nutrients helpful in lowering blood pressure, such as fiber, protein, potassium, magnesium, and calcium. DASH, now recognized as a balanced diet for the general public and not just those looking to control hypertension, recommends that people consume vegetables, fruits, fat-free or low-fat milk and milk products, whole grains, fish, poultry, beans, seeds, and nuts. Likewise, people are advised to limit their consumption of foods with significant amounts of sodium; sweets, added sugars, and beverages containing sugar; fats; and red meat. The amount of food to be consumed is calculated after taking body size, activity level, and any weight loss goal into consideration. The diet guidelines also recommend remaining physically active for optimal health.
