Maintaining healthy blood pressure is an important part of protecting your heart, blood vessels, kidneys, and overall health. High blood pressure, or hypertension, is common and can increase the risk of serious health problems when it isn't properly managed.
Your diet can play an important role in supporting healthy blood pressure. Rather than relying on one particular "superfood," research supports an overall heart-healthy eating pattern that emphasizes vegetables, fruits, whole grains, fish, beans, nuts, seeds, and low-fat dairy while limiting sodium, added sugars, and highly processed foods.
The DASH (Dietary Approaches to Stop Hypertension) eating plan is one well-established approach. It emphasizes many of the same foods featured below and has been shown to help manage blood pressure.
Here are seven nutritious foods to include in a balanced, blood-pressure-friendly diet.
Leafy Greens
Leafy green vegetables such as spinach, kale, collard greens, and Swiss chard are excellent additions to a heart-healthy diet. Many are rich in potassium, a mineral that can help counter some of the effects of sodium and support healthy blood vessel function.
If you're purchasing canned or prepared greens, check the Nutrition Facts label for sodium and choose lower-sodium options when available.
Berries
Blueberries, strawberries, raspberries, and other berries are naturally rich in nutrients and plant compounds called flavonoids. They also provide fiber and can add natural sweetness to meals without relying on added sugars.
Add fresh or frozen berries to oatmeal, plain yogurt, whole-grain cereal, or salads. Frozen berries can be an especially convenient and affordable option when fresh fruit isn't in season.
When buying packaged berries or other fruit products, choose options without added sugar whenever possible.
Oats and Other Whole Grains
Oatmeal is a convenient breakfast option that provides soluble fiber, including beta-glucan. More broadly, whole grains are an important part of heart-healthy eating patterns.
Instead of starting the day with highly processed or sugary breakfast foods, try a bowl of oatmeal topped with berries, unsalted nuts, or sliced banana. Other whole grains, such as barley, brown rice, quinoa, and whole-grain bread, can also add fiber and nutrients to meals.
When shopping, compare nutrition labels and choose whole-grain products that are lower in sodium and added sugars.
Fatty Fish
Salmon, sardines, trout, mackerel, and other fatty fish are good sources of omega-3 fatty acids and can be part of a heart-healthy diet.
The American Heart Association recommends eating fish, particularly fatty fish, regularly as part of a heart-healthy eating pattern.
Try baking, grilling, broiling, or roasting fish rather than preparing it with heavy breading or salty sauces. Pair it with roasted vegetables and a whole grain for a balanced meal.
When purchasing canned fish, look for lower-sodium varieties when available.
Beets
Beets are naturally rich in nitrates, which can contribute to the body's production of nitric oxide and support healthy blood vessel function. They also provide potassium and other nutrients.
Enjoy beets roasted, steamed, grated into salads, or incorporated into grain bowls. Beet greens are also edible and can be prepared much like other leafy greens.
If you prefer beet juice, remember that whole vegetables generally provide additional fiber and can be easier to incorporate into a balanced meal.
Garlic
Garlic is an easy way to add flavor to meals without depending on large amounts of salt. Garlic and other herbs and spices can make lower-sodium cooking more appealing while adding a variety of flavors.
Fresh garlic can be added to roasted vegetables, soups, sauces, fish, whole grains, and bean dishes.
While garlic has been studied for its potential cardiovascular benefits, it should be viewed as one component of an overall healthy diet rather than a replacement for blood pressure medication or other medical treatment.
Nuts and Seeds
Unsalted nuts and seeds can provide healthy unsaturated fats, fiber, magnesium, and other nutrients that fit well into a heart-healthy eating pattern.
Almonds, walnuts, pistachios, chia seeds, flaxseeds, pumpkin seeds, and sunflower seeds can be added to oatmeal, salads, yogurt, or whole-grain dishes.
Choose unsalted varieties when possible. Salted nuts and seeds can contain significantly more sodium, which is particularly important to consider if you're trying to manage high blood pressure.
A small handful can make a satisfying snack, but remember that nuts and seeds are calorie-dense, so portion size still matters.
Don't Forget About Sodium
Choosing nutritious foods is only part of the picture. Reducing excess sodium is also an important strategy for managing blood pressure.
The American Heart Association recommends no more than 2,300 milligrams of sodium per day, with an ideal limit of 1,500 milligrams for most adults, particularly those with high blood pressure.
Much of the sodium in the typical American diet comes from packaged, prepared, and restaurant foods rather than the salt shaker.
To reduce sodium, try:
Choosing fresh or minimally processed foods more often
Selecting low-sodium or no-salt-added canned foods
Comparing Nutrition Facts labels when shopping
Using herbs, spices, garlic, lemon, and other seasonings instead of relying heavily on salt
Choosing unsalted nuts and seeds
Limiting processed meats, salty snacks, soups, and highly processed meals
Potassium Matters, Too
Potassium can help balance the effects of sodium and support healthy blood pressure. Fruits, vegetables, beans, leafy greens, potatoes, yogurt, fish, nuts, and whole grains can all contribute potassium to your diet.
However, more potassium isn't necessarily better for everyone. People with kidney disease or certain medical conditions, as well as those taking certain medications, may need to limit their potassium intake. Talk with your healthcare professional before significantly increasing potassium intake or using potassium-based salt substitutes.
Build a Heart-Healthy Eating Pattern
Instead of focusing on individual foods, think about how your meals fit together. A DASH-style eating pattern emphasizes vegetables, fruits, whole grains, beans and legumes, nuts and seeds, fish, lean proteins, and low-fat dairy while limiting sodium, sweets, sugary beverages, processed meats, and excess saturated fat.
For example, a heart-healthy meal might include grilled salmon, roasted vegetables, brown rice, and a side salad. Breakfast could be oatmeal topped with berries and unsalted walnuts. For a snack, try plain yogurt with fruit or a small serving of unsalted nuts.
Small, consistent changes can be more sustainable than attempting to overhaul your diet overnight completely.
Food Is Only Part of Blood Pressure Management
A healthy diet is an important part of maintaining healthy blood pressure, but it isn't the only factor. Regular physical activity, maintaining a healthy weight, getting adequate sleep, managing stress, avoiding tobacco, and limiting alcohol can also support cardiovascular health.
If you have been diagnosed with high blood pressure, don't stop or change prescribed medication because you've improved your diet. Lifestyle changes and medications can work together, and your healthcare professional can help determine the best approach for you.
Make Heart-Healthy Choices Part of Your Routine
No single food can replace a healthy lifestyle or medical treatment for hypertension. However, building meals around vegetables, fruits, whole grains, fish, nuts, seeds, and other minimally processed foods can support healthy blood pressure and overall cardiovascular health.
Start with manageable changes. Add berries to breakfast, choose unsalted nuts for a snack, replace a processed side dish with vegetables, or experiment with herbs and spices instead of extra salt.
