The DASH Diet: An Easy-to-Follow Guide for Adults 55+

Key takeaways

DASH stands for Dietary Approaches to Stop Hypertension. It is an eating plan from the National Heart, Lung, and Blood Institute (NHLBI). It needs no special foods.[1]
It is built on vegetables, fruits, whole grains, low-fat dairy, fish, poultry, beans, and nuts, with less saturated fat and fewer sweets.[1]
In the original 1997 trial, the DASH diet lowered systolic blood pressure ("top number") by 5.5 mm Hg more than a typical American diet, and by 11.4 mm Hg more in people with high blood pressure.[2]
Cutting sodium on top of DASH lowered blood pressure even more.[3] NHLBI notes that 1,500 mg of sodium a day lowers blood pressure more than 2,300 mg.[1]
If you take blood pressure pills or have kidney disease or diabetes, talk with your doctor before changing your diet. Your medicines may need adjusting.

What DASH is (and isn't)

DASH is not a crash diet or a weight-loss program. It is a way of eating built on whole foods most grocery stores carry.[1] NHLBI describes it as a "heart-healthy eating style for life."[1]

NHLBI's plan asks you to:[1]

Eat vegetables, fruits, and whole grains
Include fat-free or low-fat dairy, fish, poultry, beans, nuts, and vegetable oils
Limit foods high in saturated fat, such as fatty meats, full-fat dairy, and coconut, palm kernel, and palm oils
Limit sugar-sweetened drinks and sweets

The foods it favors are rich in potassium, calcium, magnesium, fiber, and protein, and lower in sodium.[1]

Daily and weekly servings (2,000 calories a day)

This is NHLBI's target chart. Many older adults need fewer calories; NHLBI also offers worksheets for 1,200, 1,400–1,600, and 1,800–2,000 calories a day.[1]

Food group	Servings	Easy examples (one serving)
Grains (mostly whole)	6–8 a day	1 slice whole-wheat bread; ½ cup cooked oatmeal or brown rice
Vegetables	4–5 a day	1 cup raw leafy greens; ½ cup cooked vegetables
Fruit	4–5 a day	1 medium fruit; ½ cup frozen or canned (no sugar added)
Low-fat or fat-free dairy	2–3 a day	1 cup milk or yogurt
Lean meats, poultry, fish	6 or less a day	1 ounce cooked (a typical portion is 3 ounces = 3 servings)
Fats and oils	2–3 a day	1 teaspoon vegetable oil
Sodium	2,300 mg a day (1,500 mg lowers blood pressure more)	—
Nuts, seeds, beans, peas	4–5 a week	⅓ cup nuts; ½ cup cooked beans
Sweets	5 or less a week	1 tablespoon jam

What the research found

DASH is one of the best-tested eating plans in the U.S. Two federally funded feeding trials are the core evidence.

Study	Who	What they ate	Main result
DASH trial (Appel et al., NEJM 1997)[2]	459 U.S. adults; top number under 160, bottom number 80–95	Control diet, fruit-and-vegetable diet, or "combination" (DASH) diet for 8 weeks; sodium and weight kept steady	DASH lowered blood pressure 5.5/3.0 mm Hg more than control. In the 133 people with high blood pressure: 11.4/5.5 mm Hg more.
DASH-Sodium (Sacks et al., NEJM 2001)[3]	412 U.S. adults, with and without high blood pressure	DASH or control diet, each at high, medium, and low sodium for 30 days	Less sodium lowered blood pressure on both diets. Low-sodium DASH vs. high-sodium control: 7.1 mm Hg lower top number (no high blood pressure) and 11.5 mm Hg lower (with high blood pressure).

Things to know about these studies:

They were short (weeks, not years) and participants were given their food. Real-life results depend on sticking with it.[3]
Benefits were seen in women and men and in Black and other participants.[3]
They measured blood pressure, not heart attacks or strokes directly. CDC notes that higher blood pressure raises the risk of heart disease and stroke.[4] See Stroke symptoms (BE FAST).

DASH and the new 2025–2030 Dietary Guidelines

The Dietary Guidelines for Americans, 2025–2030 (released January 2026) encourage full-fat dairy with no added sugars, while also saying saturated fat should generally not exceed 10% of daily calories.[5] DASH, as written by NHLBI, uses low-fat or fat-free dairy.[1]

What this means for you: both agree on more vegetables, fruits, whole grains, and less highly processed, salty food.[1][5] If you are following DASH to manage blood pressure or cholesterol, ask your doctor or dietitian which type of dairy fits your health goals.

A 7-day sample DASH menu

This is an example only, built from the NHLBI food groups.[1] It has not been nutrient-analyzed. Portions depend on your calorie needs. Choose low-sodium or no-salt-added versions of canned and packaged foods.

Day	Breakfast	Lunch	Dinner	Snack
Mon	Oatmeal with berries and low-fat milk	Turkey and veggie whole-wheat wrap, apple	Baked salmon, brown rice, green beans	Plain yogurt
Tue	Whole-grain toast with peanut butter, banana	Lentil soup (low-sodium), side salad	Chicken stir-fry with broccoli and peppers, small portion of brown rice	Unsalted almonds
Wed	Low-fat yogurt with sliced peaches and oats	Leftover stir-fry	Bean-and-vegetable chili (no-salt-added beans), corn tortilla	Orange
Thu	Scrambled egg, spinach, whole-grain toast	Tuna (low-sodium) salad on greens, whole-grain crackers	Roast chicken, baked sweet potato, steamed carrots	Pear
Fri	Bran cereal with low-fat milk and raisins	Hummus, cucumbers, whole-wheat pita	Baked cod, quinoa, roasted zucchini	Low-fat milk
Sat	Whole-grain pancakes with fruit	Black bean and vegetable soup, side salad	Lean beef and vegetable kebabs, whole-wheat couscous	Unsalted mixed nuts
Sun	Veggie omelet, fresh fruit	Leftover kebabs in a whole-wheat wrap	Turkey meatballs (no added salt) with whole-wheat pasta and tomato sauce (no salt added)	Berries with yogurt

DASH shopping list

Produce: leafy greens, broccoli, carrots, peppers, sweet potatoes, tomatoes, berries, bananas, apples, oranges. Frozen vegetables and fruit without sauces or added sugar are fine.

Grains: oats, brown rice, quinoa, whole-wheat bread, pasta, and tortillas.

Protein: salmon, cod, canned tuna (low-sodium), skinless chicken or turkey, eggs, dry or no-salt-added canned beans and lentils, unsalted nuts and seeds.

Dairy: low-fat or fat-free milk and plain yogurt (or the dairy your clinician suggests).

Flavor without salt: garlic, onion, lemon, vinegar, black pepper, herbs, salt-free spice blends.

Read labels: FDA says 5% Daily Value or less of sodium per serving is low, and 20% or more is high.[6]

Tips that make DASH easier after 55

Add, don't just subtract. Start with one extra vegetable at lunch and dinner.
Increase fiber slowly and drink water, so your stomach can adjust.
Use frozen and pre-cut produce if chopping is hard. NIA suggests pre-cut fruits and vegetables for older adults who find slicing a challenge.[7]
Season with herbs and citrus instead of salt. NIA recommends herbs and lemon juice to cut sodium.[7]

Who should check with a doctor first

People with kidney disease. DASH is high in potassium and phosphorus-containing foods. People with chronic kidney disease may need to limit potassium, phosphorus, or protein. Work with your care team.[8]
People taking blood pressure medicines. Diet changes can lower blood pressure. Keep checking your blood pressure and tell your doctor about changes.
People with diabetes. DASH includes several servings of fruit and grains. Ask how these fit your carbohydrate goals. See Diabetic meal plan.

If you have diabetes or kidney disease, Medicare Part B covers medical nutrition therapy from a registered dietitian with a doctor's referral, and you pay nothing if you qualify.[9]

FAQ

How fast does the DASH diet lower blood pressure? In the DASH trials, participants ate the diets for 8 weeks (DASH) or 30-day periods (DASH-Sodium), and blood pressure was lower within those time frames.[2][3] Your results may differ. Track your numbers with your doctor.

Do I have to cut salt to follow DASH? DASH works on its own, but the DASH-Sodium trial found that combining DASH with lower sodium lowered blood pressure the most.[3]

Is DASH good for weight loss? DASH was designed for blood pressure. In the original trial, weight was kept steady on purpose.[2] Choosing a lower-calorie DASH worksheet may help if your clinician recommends weight loss.[1]

Is DASH the same as the Mediterranean diet? They overlap (vegetables, fruits, whole grains, fish, nuts), but DASH sets specific serving targets and emphasizes low-fat dairy and lower sodium.[1] See The Mediterranean diet.
