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

Key Components of the DASH Diet
A typical DASH diet includes plenty of vegetables, fruits, and whole grains. It incorporates fat-free or low-fat dairy products, fish, poultry, beans, nuts, and vegetable oils. Foods rich in saturated fats, such as fatty meats, full-fat dairy products, and tropical oils like coconut and palm, as well as sugar-sweetened beverages and sweets, are limited.
Daily and Weekly Nutritional Goals
The DASH diet provides daily and weekly nutritional goals. For a 2,000-calorie-a-day diet, this might include:
- Grains: 6-8 servings a day
- Vegetables: 4-5 servings a day
- Fruits: 4-5 servings a day
- Dairy: 2-3 servings a day of fat-free or low-fat products
- Meats, poultry, and fish: 6 ounces or less per day
- Nuts, seeds, legumes: 4-5 servings per week
- Fats and oils: 2-3 servings a day
- Sweets: 5 or fewer servings per week
Sodium Recommendations
The standard DASH diet limits sodium to 2,300 milligrams a day, aligning with the Dietary Guidelines for Americans. A lower sodium version restricts sodium to 1,500 milligrams per day, offering a more potent effect on blood pressure reduction.
Benefits Beyond Blood Pressure
Adhering to the DASH diet can also aid in weight loss, improve heart health, and lower the risk of diabetes, some types of cancer, and stroke. The diet’s emphasis on whole foods and nutrient-rich ingredients contributes to overall health and can help manage or prevent chronic diseases.
Practical Tips for Following DASH
- Incorporate more fruits and vegetables into your meals and snacks.
- Choose whole grains over refined grains.
- Select lean protein sources, like fish and poultry.
- Limit your intake of sodium, sweets, and sugary beverages.
- Practice portion control to manage calories for weight maintenance or loss.
Making the DASH Diet Work for You
The flexibility of the DASH diet means it can be adapted to fit any lifestyle or dietary preference. It doesn’t require special foods but instead focuses on incorporating heart-healthy foods into your daily diet. By gradually implementing these changes and focusing on nutrient-rich foods, you can improve your heart health and lower your blood pressure.
