12 Blood Pressure-Friendly Foods

Do you have high blood pressure? One way to help get a handle on hypertension is to work on crafting a nutritious diet.

Studies have shown that following a heart-healthy eating plan such as the Dietary Approaches to Stop Hypertension (DASH) diet can help lower blood pressure and reduce levels of low-density lipoprotein (aka LDL, or “bad” cholesterol). Filled with fruits, vegetables, whole grains, low-fat dairy, and nuts, the DASH Diet provides lots of blood pressure-friendly nutrients like fiber and potassium while limiting saturated fats, trans fats, and sodium.

Eating too much sodium can contribute to high blood pressure. Due in large part to salty processed foods like canned soups, cold cuts, and chips, the average American adult consumes more than 3,400 milligrams (mg) of sodium each day. The American Heart Association recommends having no more than 2,300 mg daily, with the goal being less than 1,500 mg a day, especially for people with heart disease.  

Fortunately, the following delicious, heart-friendly foods are low in sodium and fit the DASH plan. Learn how they can help improve your cardiovascular health.

If you or a loved one has high blood pressure, pomegranate juice may be a good add to your grocery list. Some research, including a 2017 meta-analysis published in the journal Pharmacological Research, suggests that drinking the ruby-red beverage each day may lead to a small decrease in systolic blood pressure, the top number in a blood pressure reading that describes the pressure your blood exerts on your arteries during a heartbeat.

Make sure to buy 100 percent pure juice with no added sugar. Better yet, eat the vitamin- and fiber-rich fruit itself. To extract its delicious arils (seeds) with less mess, cut the pomegranate in two and whack each half with a heavy spoon over a bowl. Alternately, place each half of the fruit in a bowl of water and remove the arils with your fingers. Once you’re finished, sprinkle them on your salad or in your oatmeal—or eat them on their own by the handful.

Cheap and plentiful, bananas, potatoes, and peaches are rich in potassium, which has often been linked to lower stroke risk in studies. The mineral works by encouraging your kidneys to filter more blood pressure-elevating sodium out of your bloodstream. It also helps tiny blood vessels relax and makes pressure sensors in artery walls function more efficiently. A 2016 meta-analysis published in the Journal of the American Heart Association determined that the higher your potassium intake, to a certain point, the lower your risk for stroke. Around 3,500 mg per day was associated with the lowest stroke risk.

If you’re not getting your fill, don’t take a supplement unless advised by a medical professional. It’s safest to get your potassium from food.

Want a delicious drink to help your blood pressure? Many studies suggest that tea may be the way to go. In fact, a meta-analysis published in 2020 in the journal Complementary Therapies in Medicine showed that regular tea intake had a positive effect on blood pressure in individuals with elevated blood pressure levels. This review found that drinking tea on a regular basis could lower systolic blood pressure by 4.81 mm Hg and diastolic blood pressure by 1.98 mm Hg. (Diastolic blood pressure is the bottom number in a reading and the pressure your blood exerts on your arteries as your heart rests between beats). The longer a person drank tea (beyond three months), the higher the decrease in both measures. Green tea seemed to have a more powerful effect than black tea.

How might tea lower blood pressure? It’s high in flavonoids, which may help blood vessels relax and could help keep their linings healthy. Tea is also a good substitute for sugar-sweetened, calorie-laden beverages like soda, which has been found in some studies to boost blood pressure.

When you’re making tea, keep sugar and cream to a minimum. Be aware that store-bought ice teas and chai lattes are often high in sugar and calories.

Head down the dairy aisle to help keep your blood pressure in check. Diets rich in low-fat dairy have been linked to lower rates of hypertension. These foods are filled with blood-pressure-friendly minerals like calcium, magnesium, and potassium. And since low-fat dairy is lighter on calories, it may be more helpful than full-fat dairy, which packs more calories and can contribute to weight gain and hypertension.

Research shows that eating a diet rich in whole grains is linked to a lower risk of hypertension and cardiovascular disease. Whipping up a bowl of oatmeal in the morning is a delicious and easy way to get more grains into your day.

A review published in Food Chemistry in 2022 showed that certain oat components—including soluble fiber, phenolic compounds, beta-glucan, and other compounds—may aid in lowering blood pressure. That’s a powerful package of heart-protective benefits for one little grain. Shredded wheat, popcorn, brown rice, and whole grain bread are also excellent fiber-rich additions to a nutritious diet.

Here’s a great tip for possibly improving your blood pressure: Sneak flaxseeds into your diet. You can include ground flaxseed in recipes for baked goods or mix flaxseed oil into your oatmeal, yogurt, or smoothie.

A 2022 meta-analysis published in Phytotherapy Research found that flaxseed oil consumption led to significant reductions of blood pressure in patients with metabolic syndrome or related disorders. The overall effect was a lowering of systolic blood pressure by 3.86 mm Hg and a 1.71 mm Hg reduction in diastolic blood pressure. (Metabolic syndrome is diagnosed when a person has three or more conditions including high blood pressure, high blood sugar levels, high triglycerides, or low levels of high-density lipoprotein, aka HDL or “bad” cholesterol. These conditions combine to raise one’s risk of heart disease and diabetes.)

It’s no secret: Blueberries are good for your heart health. In a 2019 study of 40 healthy men published in The Journals of Gerontology, scientists found that consuming 1 cup of daily blueberries was linked to healthier blood vessels and lower systolic blood pressure. Researchers suggested that the anthocyanin content of the fruit had something to do with the benefits. Anthocyanins are plant chemicals known as flavonoids that are found in many dark-colored fruits and vegetables.  

Similar benefits have also been seen in studies with cranberries, strawberries, and raspberries, as well as other fresh fruit.

Eaten in moderation, nuts can provide a great boost to your cardiovascular well-being. The healthy fat in walnuts helps keep artery inflammation in check, while the magnesium—about 46 mg per 1/4 cup—can help lower both your systolic and diastolic blood pressure. You'll get 81 mg of magnesium in a little handful of cashews, too. That's a good start toward the 400 mg to 420 mg of magnesium you need daily.
