A Comprehensive Guide to the DASH Diet

Introduction to the DASH Diet

The Dietary Approaches to Stop Hypertension (DASH) diet is a lifelong approach to healthy eating that is designed to help treat or prevent high blood pressure (hypertension). The DASH diet encourages you to reduce the sodium in your diet and eat a variety of foods rich in nutrients that help lower blood pressure, such as potassium, calcium, and magnesium.

The DASH diet is not a restrictive diet, but rather a flexible and balanced eating plan that is easy to follow. It has been consistently ranked as one of the best diets for overall health and for heart health by U.S. News & World Report. [1] Beyond its primary benefit of lowering blood pressure, the DASH diet can also help to lower cholesterol, reduce the risk of heart disease and stroke, and promote weight loss.

Core Principles of the DASH Diet

The DASH diet emphasizes portion size, eating a variety of foods, and getting the right amount of nutrients. The following table, based on a 2,000-calorie-a-day diet, outlines the recommended servings from each food group for the DASH diet. [1]

Food Group Daily Servings
Grains 6–8
Meats, poultry, and fish 6 or less
Vegetables 4–5
Fruit 4–5
Low-fat or fat-free dairy products 2–3
Fats and oils 2–3
Weekly Servings
Nuts, seeds, dry beans, and peas 4–5
Sweets 5 or less

Sodium Intake

A key feature of the DASH diet is limiting sodium intake. The standard DASH diet allows for up to 2,300 milligrams (mg) of sodium a day. A lower-sodium version of the DASH diet restricts sodium to 1,500 mg a day. Both versions of the DASH diet have been shown to lower blood pressure, but the lower-sodium version has a more significant effect. [1]

Getting Started with the DASH Diet

Adopting the DASH diet is a gradual process. Here are some tips to get you started:

Add a serving of vegetables at lunch and dinner.
Add a serving of fruit to your meals or as a snack.
Use only half of your usual serving of butter, margarine, or salad dressing.
Choose low-fat or fat-free condiments.
Drink low-fat or skim dairy products.
Limit meat to 6 ounces a day.
Incorporate more vegetarian meals into your week.
Snack on unsalted nuts, seeds, or raisins.
Read food labels to choose low-sodium options.
