What is the DASH Eating Plan?
The DASH (Dietary Approaches to Stop Hypertension) eating plan is a flexible and balanced eating plan that helps create a heart-healthy eating style for life. Research shows this eating plan can help lower blood pressure and may help reduce the risk of developing other chronic diseases such as diabetes, heart disease, and stroke.
The DASH eating plan requires no special foods and instead provides daily and weekly nutritional goals. The plan recommends limiting sodium intake while providing adequate nutrition. This eating pattern has been scientifically proven to lower blood pressure in just 14 days, even without weight loss.
Key Principles of the DASH Diet
The foundation of the DASH eating plan is based on:
- Choosing foods that are lower in salt and sodium
- Increasing consumption of fruits, vegetables, whole grains, and low-fat dairy products
- Including moderate amounts of fish, poultry, and nuts
- Limiting red meat, sweets, added sugars, and beverages containing sugar
- Focusing on foods rich in nutrients that help lower blood pressure, such as potassium, calcium, and magnesium
Food Groups and Recommended Servings
Grains (6-8 servings per day)
Grains include bread, cereal, rice, and pasta. Focus on whole grains because they have more fiber and nutrients than refined grains. One serving equals:
- 1 slice whole-wheat bread
- 1 ounce dry cereal
- 1/2 cup cooked rice, pasta, or cereal
Vegetables (4-5 servings per day)
Vegetables are rich in fiber, vitamins, and minerals. One serving equals:
- 1 cup raw leafy green vegetable
- 1/2 cup cut-up raw or cooked vegetable
- 1/2 cup vegetable juice
Fruits (4-5 servings per day)
Fruits are excellent sources of potassium, magnesium, and fiber. One serving equals:
- 1 medium fruit
- 1/2 cup fresh, frozen, or canned fruit
- 1/2 cup fruit juice
Dairy (2-3 servings per day)
Dairy products are major sources of calcium, protein, and vitamin D. Choose fat-free or low-fat versions. One serving equals:
- 1 cup milk or yogurt
- 1.5 ounces cheese
Lean Meat, Poultry, and Fish (6 servings or less per day)
These are rich sources of protein and B vitamins. Trim away skin and fat from meat, then broil, grill, roast, or poach instead of frying. One serving equals:
- 1 ounce cooked meat, poultry, or fish
- 1 egg
Nuts, Seeds, and Legumes (4-5 servings per week)
These are good sources of magnesium, potassium, protein, and fiber. One serving equals:
- 1/3 cup nuts
- 2 tablespoons peanut butter
- 1/2 cup cooked dry beans or peas
Fats and Oils (2-3 servings per day)
Fats help the body absorb essential vitamins and other nutrients. Focus on healthy fats such as olive oil, canola oil, and avocados. One serving equals:
- 1 teaspoon soft margarine
- 1 teaspoon vegetable oil
- 1 tablespoon mayonnaise
Sweets and Added Sugars (5 servings or less per week)
You don't have to completely eliminate sweets, but choose them wisely. One serving equals:
- 1 tablespoon sugar
- 1 tablespoon jelly or jam
- 1/2 cup sorbet
