DASH stands for Dietary Approaches to Stop Hypertension. DASH is a diet that was developed through a study sponsored by the National Heart, Lung, and Blood Institute (NHLBI) for the purpose of lowering and controlling high blood pressure
.
The DASH diet emphasizes fruits and vegetables, as well as food low in sodium, saturated fat, cholesterol, and total fat. In addition, whole grains, fish, poultry, nuts, and low-fat or fat free dairy products are part of the DASH diet. It includes foods rich in minerals such as potassium, magnesium, and calcium. The NHLBI study found that patients on the diet were able to reduce their blood pressure within two weeks.
Here are some tips on how you can get started on the DASH diet:
· Add a serving of fruits or vegetables to every meal.
· Replace a salty snack with a serving of fruit, yogurt, unsalted nuts, graham crackers, or popcorn without butter and salt.
· Use low-fat /no-fat condiments or cut any serving of butter, salad dressing, or margarine in half.
· Use only low-fat/no-fat dairy products.
· Replace a meaty meal with a vegetarian option a couple times a week, and when you do eat meat, limit the portion size to 3 ounces.
· Eat more rice, pasta (think whole grain), and dried beans.
· Keep an eye on food labels, and when it comes to sodium, try not to consume more than 1,500 mg a day.
Caloric need differs from person to person, particularly in men and women. The DASH diet includes plans based on intakes of 1,600, 2,000, 2,600, and 3,100 calories.
The NHLBI recommends the following guidelines for a 2,000-calorie DASH diet:
· 6-8 daily servings of grain
· 4-5 daily servings of vegetables
· 4-5 daily servings of fruit
· 2-3 daily servings of dairy (remember low-fat or no-fat)
· 6 or less daily servings of lean meat such as poultry or fish
· 4-5 serving a week of nuts, seeds, and legumes
· 2-3 daily servings of oils and fats
· 5 or less servings a week of sweets
Knowing what a serving size looks like can be tricky. In the case of fruits and vegetables, a serving is about a half-cup to a cup. With grains, a serving is about a half-cup of cooked rice, pasta, or cereal. A slice of whole grain bread also counts as one serving. For dairy, a serving is also about a cup. A half-cup of cooked beans equals one serving under the category of legumes, nuts, and seeds, as does 2 tablespoons of peanut butter or a third of a cup of nuts. For oils and fats, try not to exceed a tablespoon per serving. That also goes for jam and other added sugars. However, with sweets such as Jell-o or sorbet, a half-cup is fine.
As with all diets, the DASH diet works most effectively when combined with exercise.
