What DASH encourages and what it limits
DASH (Dietary Approaches to Stop Hypertension) is built around generous servings of vegetables, fruits, low-fat dairy, whole grains, legumes, nuts, and seeds, with lean poultry and fish. It limits red and processed meat, sweets and sugar-sweetened drinks, and saturated fat. A defining feature is sodium restriction, with a standard target near 2,300 mg per day and a lower target around 1,500 mg for greater blood-pressure benefit.
The pattern is naturally rich in potassium, magnesium, calcium, and fiber, the nutrients most linked to favorable blood pressure, which is the mechanism the food choices are designed around.
Why the emphasis on potassium and sodium balance
DASH works less through any single food and more through the overall mineral and fiber profile: raising potassium-rich plant foods while cutting sodium shifts the balance that influences blood pressure regulation. The plan is designed to be sustainable as an everyday eating pattern rather than a short-term restriction.
This is general educational information, not medical advice. Sodium and potassium targets can be unsafe for people with kidney disease or on certain medications, so a qualified professional should guide any therapeutic use.
