The DASH diet for high blood pressure: from clinical trial to dinner table.

Three recent studies show that a diet rich in fruits, vegetables, whole grains, and lowfat dairy products and low in fat, refined carbohydrates, and sodium can lower blood pressure either alone or in combination with other lifestyle changes. These studies have greatly expanded our knowledge of nonpharmacologic interventions to prevent and manage hypertension. They also underscore the need for diet and lifestyle counseling in the primary care setting.
