DASH Diet and Hypertension

By: Debra Minnifield, RN

The “Dash Diet”, which stands for Dietary Approaches to Stop Hypertension, is credited with effectiveness in reducing blood pressure in African Americans and older adults. The focus of the DASH diet is to lower and control blood pressure. The use of this diet could reduce blood pressure by a few points in only two weeks and reduce it eight to fourteen points over time. Its other health benefits include protection against heart disease, stroke, osteoporosis and even diabetes. Use of the DASH diet may even potentiate the action of antihypertensive medications and decrease insulin resistance.

The Dash Diet formed the basis for the new SDA My Pyramid and is recommended by:

• The National Heart, Lung, and Blood Institute

• The American Heart Association

• The 2005 Dietary Guidelines for Americans

• US guidelines for treatment of high blood pressure

The DASH diet controlling portion sizes and consists of whole grains, low fat dairy products, fish poultry, legumes fruits, and vegetables. The diet is low in saturated fat, sodium, cholesterol and total fat. However, the diet is high in protein, magnesium, calcium and potassium. Red meat and sweets may be consumed in moderation.

As advocates, nurses can educate and empower clients to take control of their health by encouraging the use of the DASH diet. Nurses should perform thorough assessments and urge patients to make lifestyle modifications, such as engaging regularly in appropriate exercise, limiting their alcohol intake and avoiding tobacco.
