High Blood Pressure and the DASH Diet

One step to lower high blood pressure — incorporate the DASH diet into your lifestyle. Doctors recommend:

Eating more fruits, vegetables, and low-fat dairy foods
Cutting back on foods that are high in saturated fat, cholesterol, and total fat
Eating more whole grain products, fish, poultry, and nuts
Eating less red meat and sweets
Eating foods that are rich in magnesium, potassium, and calcium

The DASH diet, which stands for Dietary Approaches to Stop Hypertension, is an example of such an eating plan. In studies, patients who were on the DASH diet reduced their blood pressure within two weeks. Another diet — DASH-Sodium — calls for reducing sodium (salt) to 1,500 mg a day (about 2/3 teaspoon). Studies of patients on the DASH-Sodium plan significantly lowered their blood pressure.

Is Your Blood Pressure in Check?
Starting the DASH Diet

The DASH diet calls for a certain number of servings daily from various food groups. The number of servings you require may vary, depending on your caloric need. When beginning the diet, start slowly and make gradual changes. Consider adopting a diet plan that allows 2,400 milligrams of salt per day (about 1 teaspoon) and then once your body has adjusted to the diet further lower your salt intake to 1,500 mg per day (about 2/3 teaspoon). These amounts include all salt consumed, including that in food products, used in cooking, and added at the table.

Here are some tips to get you started on the DASH diet:

Add a serving of vegetables at lunch and at dinner.
Add a serving of fruit to your meals or as a snack. Canned and dried fruits are easy to use.
Use only half the butter, margarine, or salad dressing, and use low-fat or fat-free condiments.
Drink low-fat or skim dairy products three times a day.
Limit meat to six ounces a day. Try eating some vegetarian meals.
Add more vegetables, rice, pasta, and dry beans to your diet.
Instead of typical snacks (chips, etc.), eat unsalted pretzels or nuts, raisins, graham crackers, low-fat and fat-free yogurt and frozen yogurt; unsalted plain popcorn with no butter, and raw vegetables.
Read food labels carefully to choose products that are lower in sodium.

Staying on the DASH Diet

The following is a list of food groups and suggested serving amounts for the DASH diet:

Grains: 7-8 daily servings
Vegetables: 4-5 daily servings
Fruits: 4-5 daily servings
Low-fat or fat-free dairy products: 2-3 daily servings
Meat, poultry and fish: 2 or less daily servings
Nuts, seeds, and dry beans: 4-5 servings per week
Fats and oils: 2-3 daily servings
Sweets: try to limit to less than 5 servings per week
