Quick answer: The DASH diet (Dietary Approaches to Stop Hypertension) is a heart-healthy, plant-forward eating pattern that emphasizes fruits, vegetables, whole grains, beans, nuts, and low-fat dairy, while limiting sodium, added sugars, saturated fat, and red/processed meats. It's designed to lower blood pressure and can improve cholesterol. Many people see meaningful reductions—especially when they also reduce sodium to 1,500–2,300 mg/day.

What is the DASH diet?
DASH is an NIH-backed eating plan from the National Heart, Lung, and Blood Institute (NHLBI). It emphasizes minimally processed foods such as vegetables, fruits, whole grains, legumes, nuts, seeds, lean proteins (especially fish and poultry), and low-fat dairy. The plan also encourages limiting sodium, added sugars, sweets, and foods high in saturated fat. This approach can be used both to prevent and manage high blood pressure, and many people also experience improvements in LDL cholesterol levels.
Why it works (the core nutrients)
DASH foods are naturally rich in potassium, magnesium, and calcium—nutrients that help regulate blood pressure—while also being high in fiber and lower in saturated fat than a typical Western diet.
Potassium, in particular, helps counterbalance the blood-pressure-raising effects of sodium by relaxing blood vessel walls and helping the kidneys excrete excess sodium. This is why the diet emphasizes potassium-rich foods like leafy greens, bananas, potatoes, and beans. Pairing this nutrient-dense pattern with lower sodium amplifies the benefits.
The fiber content of DASH also plays a significant role. High-fiber foods slow digestion, support gut health, and help you feel satisfied longer—all of which contribute to maintaining a healthy weight, another factor in blood pressure management. For a deeper dive into fiber's health benefits, see our Ultimate Guide to Dietary Fiber.
Daily servings & sodium targets
Use these typical 2,000-calorie targets from NIH-NHLBI. Adjust portions up or down for your calorie needs.
| Food group | Daily/weekly goal | Examples |
|---|---|---|
| Vegetables | 4–5 servings/day | Leafy greens, broccoli, carrots, tomatoes |
| Fruits | 4–5 servings/day | Berries, citrus, melons, apples |
| Grains (mostly whole) | 6–8 servings/day | Oats, brown rice, whole-wheat bread |
| Low-fat/fat-free dairy | 2–3 servings/day | Low-fat yogurt, milk, kefir |
| Lean meats, poultry, fish | ≤6 oz/day | Skinless poultry, fish, lean cuts |
| Nuts, seeds, legumes | 4–5 servings/week | Beans, lentils, almonds, peanuts |
| Fats & oils | 2–3 servings/day | Olive/canola oil, light dressings |
| Sweets/added sugars | ≤5 servings/week | Small portions; choose low-fat options |
Sodium: Choose a level that fits your health needs—standard 2,300 mg/day or lower 1,500 mg/day for extra BP reduction. Ask your clinician which target is right for you.
What the evidence shows
Blood pressure: The original DASH feeding trial and a follow-up sodium trial showed clinically meaningful BP drops, with greater effects when DASH is combined with lower sodium. Multiple meta-analyses confirm significant average reductions in both systolic and diastolic BP.
Cholesterol: Research on DASH-style dietary pattern shows modest improvements in lipid markers, including LDL and total cholesterol.
Cardiovascular outcomes: Evidence shows improvements in cardiovascular risk factors; evidence for hard outcomes (heart attacks, strokes) is still evolving.
How to get started (easy swaps)
- Make half your plate produce (fresh, frozen, or no-salt-added canned).
- Swap refined grains for whole (oats, brown rice, whole-wheat pasta).
- Pick low-fat dairy most of the time; try yogurt or kefir if you prefer.
- Choose lean proteins (fish, poultry, beans/lentils) most meals.
- Check labels for sodium; aim for ≤140 mg per serving when possible.
- Plan your week: Here's a 7-day DASH sample menu from NIH. If meal planning feels overwhelming, our Complete Meal Prep Guide walks through batch cooking strategies that work with any eating pattern, including DASH.
Support from Clean Eatz Kitchen
Hitting DASH goals is easier when meals are planned. Our calorie-controlled, high-produce meal plans help keep sodium reasonable and fiber high—the Weight Loss Meal Plan and Build Your Meal Plan options both emphasize lean proteins and vegetables that align with DASH principles. Fill gaps with protein-forward snacks, and check exact macros on our Nutrition Info page.
FAQs
Is DASH for weight loss?
DASH wasn't designed as a weight-loss diet, but people may lose weight when it is combined with a calorie deficit and regular activity. Its approach can aid satiety and helps you cook/eat more whole foods. For a complete breakdown of foods that support fat loss, see our Best Foods for Weight Loss guide. If you're interested in understanding how to balance your macros for weight loss, our guide to macronutrient ratios covers the details.
How low should I go on sodium?
The goal is to lower sodium toward 2,300 mg/day; many with hypertension see additional reductions targeting ~1,500 mg/day. Your ideal target depends on health status and clinician guidance.
Can I do DASH if I'm vegetarian or dairy-free?
Yes. DASH is flexible: lean proteins can be plant-based (tofu, tempeh, beans/lentils), and dairy can be replaced with fortified alternatives—just watch for added sugars/sodium.
What if I have chronic kidney disease (CKD)?
DASH-style eating can still be helpful, but some DASH foods are high in potassium. If you have moderate-to-advanced CKD or a history of hyperkalemia, talk to your clinician/dietitian before using salt substitutes or significantly increasing high-potassium foods. They can tailor a lower-potassium version for you.
How is DASH different from Mediterranean?
Both are plant-forward. DASH more explicitly emphasizes low-fat dairy and specific sodium targets; Mediterranean features more olive oil, fish, and nuts. Either is heart-healthy when built around minimally processed foods.
