Managing Hypertension with the DASH Diet



According to the National Heart, Lung, and Blood Institute (NHLBI), your blood pressure can be unhealthy even if it stays only slightly above 120/80 mm Hg. The higher above that level, the greater your health risk. Over time, high blood pressure makes your heart work too hard. This can cause stroke, hardening of the arteries, heart failure, kidney disease, and even blindness.

Why this diet works

Why is the DASH diet so effective at reducing blood pressure?




Doing the DASH

The DASH diet is a 2,000-calorie diet that includes:

  • Six to 8 daily servings of grains and grain products, such as whole wheat bread, cereal, oatmeal, crackers, unsalted pretzels, and popcorn. A serving size is 1 slice of bread, 1 cup of ready-to-eat cereal, or a half-cup of rice, pasta, or cereal.

  • Four to 5 daily servings of vegetables — the darker in color, the better. A serving size is 1 cup of raw leafy vegetables, a half-cup of cooked vegetables, or 6 ounces of vegetable juice.

  • Four to 5 daily servings of fruit. A serving is 1 medium fruit, quarter-cup of dried fruit, half-cup of fresh, frozen or canned fruit, or 6 ounces of fruit juice.

  • Two or 3 daily servings of low-fat or fat-free dairy products. A serving is 8 ounces of milk, 1 cup of yogurt, or 1½ ounces of cheese.

  • Six or fewer daily servings of lean meat, poultry, or fish. A serving is 1 ounce of cooked meats, skinless poultry, or fish.

  • Four to 5 servings per week of nuts, seeds, and dry beans. A serving is one-third cup or 1½ ounces of nuts, 1 tablespoon or half-ounce of seeds, or half-cup cooked dried beans.

  • Two to 3 small daily servings of fats and oils like olive oil and low-fat salad dressing. A serving is 1 teaspoon soft margarine, 1 tablespoon low-fat mayonnaise, 2 tablespoons light salad dressing, or 1 teaspoon vegetable oil.

  • Five or fewer servings per week of sweets like maple syrup, sorbet, or gelatin. A serving is 1 tablespoon sugar, 1 tablespoon jelly or jam, half-ounce jellybeans, or 8 ounces of lemonade.

Although the DASH diet isn't designed for weight loss, it can easily promote it if you reduce the number of servings you eat. Most of the food the diet features is low in energy density. This means it's big on volume and low in calories.

Still, there are parts of the DASH diet that may not be easy to follow. For one, it's packed with dark-colored fruits and vegetables, so be prepared to be choosier at the supermarket. Also, if it's very different from what you normally eat, it may be hard to adjust.

If you're serious about following the diet, it's a good idea to work with a registered dietitian (R.D.) for support and guidance. (For the names of R.D.s in your area who know about the DASH diet, visit the Academy of Nutrition and Dietetics.)

Moving forward

If you decide to go it alone, adopt the DASH diet gradually. By doing so, you'll be more likely to stick to it long-term.

For example, add 1 more serving of vegetables at lunch and dinner if you eat only 1 or 2 servings a day now. You might also add fruit to meals and snacks if you now only have juice for breakfast. In addition, slowly increase your dairy products to 3 servings per day. Try drinking skim milk with lunch or dinner, instead of soda, alcohol, or tea.

To get the most out of the DASH, lose weight if you need to and exercise regularly. Thirty minutes of moderate exercise 4 to 5 days a week is recommended.
