Describe the DASH eating plan
Several studies have shown that a significant reduction in blood pressure can be achieved by following a diet that emphasizes fruits, vegetables, and whole grains and includes low-fat milk products, poultry, fish, and nuts. The diet tested in these studies, now known as the DASH Eating Plan, provides more fiber, potassium, magnesium, and calcium than the typical American diet. The diet also limits red meat, sweets, sugar-containing beverages, saturated fat (to 7 percent of kcalories), and cholesterol (to 150 milligrams per day), so it is beneficial for reducing CHD risk as well.
