🩺 What Is the DASH Diet?
DASH stands for Dietary Approaches to Stop Hypertension. It’s a clinically proven eating plan specifically designed to prevent and manage high blood pressure (hypertension).
Developed by the National Heart, Lung, and Blood Institute (NHLBI), the DASH diet focuses on nutrient-rich, heart-healthy foods that lower blood pressure without the need for medication in many cases.
🧠 Why the DASH Diet Works
The DASH diet lowers blood pressure because it is:
- Low in sodium
- High in potassium, magnesium, and calcium
- Rich in fiber and lean protein
- Balanced and easy to follow long-term
Studies show that people following the DASH diet can reduce systolic blood pressure by 8–14 mm Hg, a significant improvement for individuals with prehypertension or stage 1 hypertension.
🍎 DASH Diet Food Groups
Here’s what to eat — and how much — on a standard 2,000-calorie/day DASH plan:
| Food Group | Daily Servings | Examples |
|---|---|---|
| Vegetables | 4–5 servings | Broccoli, spinach, carrots, tomatoes |
| Fruits | 4–5 servings | Apples, oranges, bananas, berries |
| Whole Grains | 6–8 servings | Brown rice, whole wheat bread, oats |
| Low-Fat Dairy | 2–3 servings | Skim milk, yogurt, low-fat cheese |
| Lean Proteins | 2 or less | Chicken, fish, tofu, eggs |
| Nuts/Seeds/Legumes | 4–5 per week | Almonds, beans, lentils, sunflower seeds |
| Fats/Oils | 2–3 servings | Olive oil, avocado, soft margarine |
| Sweets | 5 per week | Dark chocolate, fruit sorbet |
🚫 Foods to Avoid on the DASH Diet
To effectively lower blood pressure, limit or eliminate:
- Processed and packaged foods (chips, canned soups)
- Salted snacks and fast foods
- Sugary drinks and sodas
- Fatty cuts of red meat
- Alcohol (limit to 1 drink/day for women, 2 for men)
🔄 Sodium Guidelines
- Standard DASH Diet: 2,300 mg/day (about 1 teaspoon of salt)
- Lower Sodium Version: 1,500 mg/day (ideal for those with high BP or heart disease)
Pro tip: Use herbs, lemon juice, garlic, and spices instead of salt for flavor!
