The healthiest diet?

The Nutrition Action Newsletter that if you want to protect your heart, eat more fruits and veggies, and cut unhealthy carbs, one of the healthiest diets—it’s endorsed by the American Heart Association, the American College of Cardiology, and other health authorities—is DASH (Dietary Approaches to Stop Hypertension).

That’s because a DASH-style diet is low in saturated fat, sugar, and salt, and rich in fruits and vegetables. It’s also rich in nutrients like potassium, magnesium, calcium, and fiber.

In 1997, a landmark study found that a DASH diet could lower blood pressure as well as some prescription drugs. That news was a bombshell because high blood pressure (hypertension) is a major risk factor for heart attacks and strokes.

The OmniHeart study diets

Then, in 2005, came another news flash. The OmniHeart study reported that two variations of the DASH diet were even better for your heart than the original:

The higher-protein variation replaced some of DASH’s carbs with protein—half from plant sources (like beans, peas, and nuts) and a half from animal foods (like fish, lean poultry, and low-fat dairy).

The higher-healthy-fat variation was a Mediterranean-style diet. It replaced some of DASH’s carbs with healthy fats like oils, salad dressing, mayonnaise, nuts, fatty fish, and avocado. The oils—like canola, olive, and soybean—were polyunsaturated or monounsaturated, not saturated like coconut or palm.

The two OmniHeart diets beat the original DASH diet because they were better at lowering LDL (“bad”) cholesterol and triglycerides.

Our take on the OmniHeart Diet

We’ve created a hybrid of the two OmniHeart diets, with a “wild card” that lets you eat one extra serving of carbs, protein, or healthy fat each day. Here are examples of a day’s worth of food for omnivores or vegetarians.

Here’s how many servings to aim for—and what a typical serving consists of—if you eat roughly 2,000 calories a day. (Click here for a chart with extra tips that you can download, save, and print.)


Note: The Wild Card lets you add about 120 calories’ worth of fish & poultry, fats & oils, whole grains, desserts & sweets, or any other category above.

Daily goals (for roughly 2,000 calories a day):

  • Saturated fat: 14 g
  • Sodium: No more than 2,300 mg
  • Fiber: at least 30 g
  • Protein: 105 g
  • Potassium: 4,700 mg
  • Magnesium: 500 mg
  • Calcium: 1,200 mg

Don’t want to count servings of this or that? Fill half your plate with fruits and vegetables, shrink the unhealthy carbs, replace fats (like butter) with oils, cut back on salt, and limit added sugar. That’ll get you most of the way there.

Make vegetables the main course

If you want 11 servings of vegetables or fruit a day, they’re going to fill up at least half of your plate at lunch and dinner. It’s easy to polish off 3 or 4 pieces of fruit as snacks or with breakfast or lunch. But when you’re shooting for 6 to 8 servings of vegetables a day, it makes sense to make them part of the main dish like stir-fried vegetables, vegetable curry, vegetable fajitas, or a main-dish salad, which could have chunks of chicken, fish, or tofu mixed in.

Used to having chicken as your main dish for dinner? Surround a small portion—about the size of a deck of cards—with enough side-dish vegetables or salad to reach your veggie total.

It’s not just that you need to boost the vegetables, but that by eating more of them, you’re eating less of other foods…like grains.

Go easy on grains

Even whole grains are limited to four servings a day if you’re shooting for roughly 2,000 calories. And a serving is a thin (1 oz.) slice of bread, not a typical (4 oz.) bagel.

Eat a small bowl of cereal for breakfast and a sandwich at lunch, and you’re left with just a half cup of cereal, rice, or pasta for dinner.

A half cup isn’t much. It wouldn’t even fill up a tennis ball. Solution: bulk up your serving with vegetables. Add sautéed or roasted veggies to your cooked brown rice or quinoa. Or toss your whole wheat pasta with grilled or sautéed mushrooms, bell peppers, and/or zucchini, or with sautéed spinach or kale.
