DASH diet for blood pressure

What the DASH diet is

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 and low-fat dairy. It also limits sodium, added sugars, sweets, red and processed meats, and foods high in saturated fat.

People use it both to prevent and to manage high blood pressure, and many also see modest improvements in LDL cholesterol. There's no special food to buy and no phase to get through. It's a pattern, not a protocol.

It isn't a replacement for treatment, either. If you've been prescribed blood pressure medication, DASH goes alongside it, and any change to the medication is a decision for you and your doctor.

Why the DASH diet works

Why does the DASH diet lower blood pressure?

No single nutrient explains DASH. In the original trial, a diet rich in fruits and vegetables alone lowered systolic pressure by 2.8 mm Hg, and adding low-fat dairy with less saturated and total fat took that to 5.5 mm Hg. The pattern did more than the produce.

DASH daily servings & sodium targets

How much of each food does DASH call for?

These are the typical 2,000-calorie targets from NHLBI. Adjust portions up or down for your calorie needs. The serving sizes matter as much as the counts, because a DASH serving is smaller than most people assume.

Run the vegetable and fruit lines and you get 8 to 10 servings a day, which sounds like a lot until you see it's about 4 to 5 half-cups each. A cup of berries at breakfast and a big salad at lunch cover nearly half of it.

Reducing salt on the DASH diet

How do you cut salt on the DASH diet?

Reducing salt is less about giving up flavor than about changing where the sodium comes from. Over 70% of it comes from packaged and prepared foods, so the shaker is the smallest part of the problem. Don't try to remove it all at once. Pick one or two high-sodium habits and replace them with choices you can repeat every day.

DASH diet research & evidence

What does the DASH research show?

The direction is consistent. The size isn't, because it depends on who was studied, what they ate before and how tightly the food was controlled.

Key DASH trials & reviews

How to start the DASH diet

How do you start the DASH diet?

• Make half your plate produce: fresh, frozen or no-salt-added canned all count.
• Swap refined grains for whole grains: oats, brown rice, whole-wheat pasta.
• Pick low-fat dairy most of the time. Try yogurt or kefir if you prefer.
• Choose lean proteins for most meals: fish, poultry, beans and lentils.
• Check labels for sodium. Aim for 140 mg or less per serving when you can.
• Plan your week. NHLBI publishes a free 7-day DASH sample menu. If meal planning feels overwhelming, our Complete Meal Prep Guide walks through batch cooking strategies that work with any eating pattern, including DASH.

Practical tips for DASH adherence

How do you stick with the DASH diet?

DASH is easier to follow when it isn't all-or-nothing. Start with the changes that take the least effort and pay off the most. You might add fruit to breakfast, swap refined grains for whole grains, or make vegetables a permanent part of lunch and dinner.

• Keep convenience in mind. Frozen vegetables, canned beans, plain yogurt and simple pantry staples make DASH meals much easier on busy days.
• Plan ahead a little. A few planned meals, some extra portions and healthy snacks on hand make it less likely you'll fall back on fast food when you're tired.
• Build on what you already eat. Familiar foods are more likely to become routine than unfamiliar recipes.
• Make the salad bigger when you eat out. Choose grilled or baked options and keep sauces on the side.
• Read labels until it's automatic. It gets faster, and you'll start to spot hidden sodium on your own.

Give yourself room as well. One salty dinner doesn't cancel the pattern, because a pattern is what you do most of the time. Small, steady changes are the easiest to keep, and eventually they stop feeling like a diet.

DASH diet safety & further reading

Who should talk to a doctor before starting?

If you take blood pressure medication, have diabetes or have kidney concerns, your provider can help you apply these recommendations safely. Don't change or stop a medication based on a diet you've started. Bring your home readings to the appointment instead.

Where do prepared meals fit with DASH?

Hitting DASH goals is easier when meals are planned, and we'd like to help with that part. Still, you should have the numbers before deciding. A median meal on our current menu has 750 mg of sodium, which is half of a 1,500 mg day and about a third of a 2,300 mg day. Three of those a day comes to 2,250 mg, with only 50 mg left for everything else.

So they're a better fit at the 2,300 mg level, used for a meal or two rather than all three. Two meals are the exception: Basic Diced Chicken & Red Potatoes at 360 mg and Basic Chicken Strips & Rice at 380 mg meet the FDA's low-sodium main dish rule. Three meals top 1,000 mg. Our Nutrition Info page lists sodium, fiber, cholesterol and calories for every meal, and you can sort by them.

If the hard part is cooking on a Tuesday rather than knowing what DASH asks for, our meal plans are portioned and take a few minutes in the microwave. Build A Meal Plan lets you pick meals one by one, with goal filters that include Heart Healthy. Check the sodium on each meal it shows. Add a side of vegetables or fruit to move toward your DASH servings, and check the sodium on any of our snacks too. Your clinician's target wins over any of this.
