Quick Summary

The DASH diet is a flexible eating plan focusing on whole foods like produce, whole grains, and lean protein, while limiting sodium and unhealthy fats to manage blood pressure.

Key Points

Emphasize whole foods: The DASH diet is built on a foundation of fruits, vegetables, whole grains, and lean proteins.

It's not just for hypertension: The diet has also been shown to help lower cholesterol, aid in weight loss, and reduce the risk of other chronic diseases.

Understanding the DASH Diet

The Dietary Approaches to Stop Hypertension (DASH) diet is a flexible, balanced, and sustainable eating plan designed to help prevent and treat high blood pressure. It focuses on foods rich in blood pressure-lowering nutrients such as potassium, calcium, and magnesium, while limiting sodium and saturated fat.

What does DASH emphasize and limit?

The DASH diet emphasizes whole, nutrient-dense foods:

Fruits and Vegetables: Rich in potassium, magnesium, and fiber.
Whole Grains: Providing fiber and nutrients.
Low-Fat or Fat-Free Dairy: For calcium without excess saturated fat.
Lean Meats, Poultry, and Fish: Protein sources lower in fat.
Nuts, Seeds, and Legumes: Sources of healthy fats, protein, and fiber.

To lower blood pressure, the DASH diet limits:

Sodium: The standard plan limits intake to 2,300 mg/day, with a stricter 1,500 mg version.
Saturated and Trans Fats: Found in fatty meats, full-fat dairy, and certain oils.
Sugar-Sweetened Beverages and Sweets: Kept to a minimum.

Food Groups and Serving Sizes on DASH

For a 2,000-calorie diet, typical daily servings include:

Grains: 6–8 servings (e.g., 1 slice whole-wheat bread or ½ cup cooked rice).
Vegetables: 4–5 servings (e.g., 1 cup raw leafy greens or ½ cup cut vegetables).
Fruits: 4–5 servings (e.g., 1 medium fruit or ½ cup fresh/frozen fruit).
Low-fat or fat-free Dairy: 2–3 servings (e.g., 1 cup milk or yogurt).
Lean Meats, Poultry, and Fish: 6 or fewer 1-ounce servings.
Nuts, Seeds, and Legumes: 4–5 servings weekly (e.g., 1/3 cup nuts or ½ cup cooked beans).
Fats and Oils: 2–3 servings (e.g., 1 tsp vegetable oil).
Sweets: 5 or fewer servings weekly (e.g., 1 tbsp sugar or ½ cup sorbet).
