The Top Fall Fruit for Supporting Healthy Blood Pressure, Per a Dietitian

Pomegranate season arrives in the fall, and the fruit offers more than just a sweet-tart flavor. It may also help support healthy blood pressure. While it is not a substitute for blood pressure medication, pomegranate can be a flavorful part of a heart-friendly eating pattern.

• Why this matters: High blood pressure raises the risk of heart disease and stroke.
• What you can do: Add pomegranate to meals as a snack, in salads or oats, or sprinkled over roasted vegetables.
• The payoff: Pomegranates contain antioxidants and other compounds that may help support healthy blood pressure.

The Possible Blood Pressure Benefits

Pomegranates contain nutrients and plant compounds that may help reduce both systolic blood pressure, the top number in a reading, and diastolic blood pressure, the bottom number.

Studies have found that pomegranates can lower systolic blood pressure by 3.5–8 mmHg and diastolic blood pressure by 1.5–3 mmHg. People who already have hypertension may see the greatest benefit. That matters because even a 5 mmHg drop in systolic blood pressure can reduce the risk of major heart events, including heart attacks and strokes, by about 10%.

These findings are encouraging, but study results have not been completely consistent, and many of the research trials used pomegranate juice or extracts rather than whole fruit. More research is still needed to confirm whether eating the fruit itself produces the same effect. Even so, pomegranates remain a strong choice for a heart-healthy diet because they offer antioxidants, fiber, and other useful nutrients.

Why Pomegranates May Help

Pomegranates bring together several nutrients and plant compounds that may support blood vessel health. Here are three reasons the fruit may be linked to lower blood pressure:

1. They Are Rich in Antioxidants

Pomegranates are especially high in polyphenols, a class of compounds that act as antioxidants. One group of these polyphenols is called ellagitannins, and research suggests they may help reduce blood pressure. One review found that fruits rich in ellagitannins helped lower blood pressure in people with hypertension.

Polyphenols also help protect cells from unstable molecules known as free radicals. When free radicals accumulate, they can damage blood vessels and contribute to inflammation and high blood pressure. Pomegranate supplements may also help lower inflammatory markers tied to heart disease, though more research is needed.

2. They May Help Blood Vessels Relax

Healthy blood vessels need to widen and tighten as needed so blood can flow smoothly. When vessels become stiff or narrow, blood pressure can rise.

The polyphenols in pomegranate may help blood vessels relax by influencing an enzyme called angiotensin-converting enzyme, or ACE. ACE helps produce a hormone that narrows blood vessels and raises blood pressure. Lab and animal research suggests that some compounds in pomegranate may reduce ACE activity, which could help vessels relax and support easier blood flow.

3. They Provide Potassium

Potassium is an essential mineral that helps regulate blood pressure by balancing sodium and supporting healthy blood vessel function. A half-cup of pomegranate seeds has about 200 milligrams of potassium, or roughly 6% to 8% of what adults need each day.

Potassium helps the body excrete extra sodium through urine and also helps relax blood vessel walls. Both effects support healthy blood pressure. Potassium-rich foods are also an important part of the Dietary Approaches to Stop Hypertension, or DASH, diet, which has been shown to lower blood pressure.

Easy Ways to Add Pomegranate to Your Diet

Pomegranates fit easily into both sweet and savory dishes, or you can enjoy the seeds on their own. Try these ideas:

• In a salad: Toss pomegranate seeds with leafy greens, avocado, and a vinaigrette.
• In a bowl: Add them to quinoa or brown rice with roasted vegetables and chickpeas.
• On top of granola or yogurt: Sprinkle on a few tablespoons for a sweet crunch.
• Over roasted vegetables: Pair pomegranate with roasted squash, sweet potatoes, or Brussels sprouts.
• In a marinade: Mix pomegranate juice with olive oil, garlic, and herbs for chicken or vegetables.

Fresh pomegranates are typically available from fall into early winter. You can also find ready-to-eat arils or frozen pomegranate seeds.
