Bananas are the most popular fruit in the U.S<\/a>., purchased more often than apples<\/a>, berries<\/a> and grapes<\/a>. They\u2019re one of the most convenient, affordable fruits, and there\u2019s certainly no shortage of delicious ways to eat them. Bananas taste great with oatmeal<\/a>, in smoothies<\/a>, paired with nut butter or enjoyed on their own, freshly peeled.<\/p>\n

It\u2019s the foods we eat most often that impact our health the most\u2014including blood pressure. Considering that nearly half of all adults in the U.S. have high blood pressure<\/a>, the connection between diet and blood pressure is something everyone should have top of mind.<\/p>\n

Don\u2019t think it\u2019s that big of a deal? Consider this fact from the Centers for Disease Control and Prevention: In 2023, the most recent year data is available, high blood pressure<\/a> was the primary or contributing cause of 664,470 deaths in the U.S.<\/p>\n

Since bananas are the most widely consumed fruit in the U.S., it\u2019s worth it to think about how this popular fruit impacts blood pressure\u2014for better or for worse. We talked to three cardiologists to find out.\u00a0<\/p>\n

According to Dr. Laura Isaacson, MD, RD, CDCES,<\/strong><\/a> a cardiologist, registered dietitian and the senior director of clinical dietetics at Vida Health<\/a>, bananas are very good for blood pressure. \u201cBananas can help to lower blood pressure because they are rich in potassium,\u201d she says.<\/p>\n

Dr. Isaacson explains that potassium helps the body get rid of excess sodium through the kidneys, reducing fluid retention and easing pressure on blood vessel walls. That means that eating a banana can be especially beneficial if you\u2019ve recently eaten something salty.<\/p>\n

While bananas certainly support blood pressure, don\u2019t expect a major decrease immediately after eating one. Dr. Ragavendra Baliga, MBBS<\/strong><\/a>,<\/strong> a cardiologist at The Ohio State University Wexner Medical Center, says that the decrease is more moderate, both immediately and long-term. Echoing Dr. Isaacson, he explains that the potassium in bananas blunts the effects of sodium, leading to a small decrease in blood pressure.<\/p>\n

But that doesn’t mean the decrease isn’t noteworthy. Dr. Rajeev L. Narayan, MD, <\/strong><\/a>a cardiologist with Nuvance Health, explains it this way: \u201cPotassium helps the body counterbalance sodium, which is one of the biggest dietary drivers of high blood pressure. It also helps blood vessels relax, improving blood flow and lowering pressure within the arteries. In simple terms, potassium helps take the pressure off your blood vessels\u2014literally.\u201d<\/p>\n

Wondering if eating two bananas will have a bigger impact than eating just one? It won\u2019t. \u201cThe benefits plateau,\u201d Dr. Baliga says.<\/p>\n

Dr. Narayan agrees. \u201cEating more doesn\u2019t necessarily mean better results,\u201d he explains, adding that one a day is enough to benefit the cardiovascular system. \u201cEating multiple bananas won\u2019t double the blood-pressure effect and may add excess calories or potassium.”<\/p>\n

It is important to note that bananas can interfere with certain medications. \u201cPeople taking medications that raise potassium levels\u2014such as ACE inhibitors, ARBs [used to treat high blood pressure, heart failure and kidney disease] or potassium-sparing diuretics\u2014should be mindful. Patients with kidney disease should also be cautious. If you\u2019re on heart or blood pressure medications, it\u2019s always smart to ask before dramatically increasing potassium intake,\u201d Dr. Narayan says.<\/p>\n

How Eating Bananas Regularly Supports Cardiovascular Health<\/p>\n

If you do eat bananas regularly long-term, your entire cardiovascular system will benefit. Besides supporting blood pressure, all three cardiologists say that the fiber and antioxidants in bananas help lower LDL cholesterol and contribute to overall improved cardiovascular health.<\/p>\n

One 2024 study published in Frontiers in Nutrition<\/a> found that people with high blood pressure who regularly ate apples and bananas three to six times a week had a noteworthy decrease in their risk of cardiovascular disease.<\/p>\n

\u201cBananas contain soluble fiber, particularly pectin, which helps lower LDL cholesterol by binding to it in the gut, so less is absorbed into the bloodstream,\u201d Dr. Isaacson says. She also points out that bananas are filling, which means that bananas can play a role in weight management. This is important because maintaining a healthy weight is key to looking after your heart.<\/p>\n

Besides the potassium and fiber, Dr. Isaacson explains that the magnesium in bananas plays an important role in maintaining a steady heart rhythm and healthy muscle function. \u201cIt helps the heart to contract and relax efficiently and supports better blood flow by relaxing blood vessels,\u201d she explains.<\/p>\n

Bananas are certainly a heart-healthy food, but all three cardiologists emphasize that what\u2019s most important is to eat a wide range of nutrient-rich foods. Eating a banana a day can\u2019t make up for having unhealthy dietary habits the rest of the day.<\/p>\n

\u201cBananas are helpful, but they\u2019re not a replacement for medication or other lifestyle changes when those are needed. No single food fixes blood pressure, but bananas are a great piece of the puzzle,\u201d Dr. Narayan says.<\/p>\n

Remember, bananas are just one of many fruits that support blood pressure. Eating them regularly is a great habit, but so is switching it up and having berries or an apple every now and then too.<\/p>\n
