You’ve probably heard that bananas are rich in potassium, a mineral that can help maintain healthy blood pressure. However, the benefits may depend on each person’s health needs and goals.
Bananas are rich in potassium. A medium banana contains about 422 milligrams of potassium, or about 9 percent of your recommended daily intake (4,700 milligrams for adults).
Potassium performs a number of crucial functions in the body. This mineral:
- Helps muscles contract
- Supports nerve function
- Keeps your heart rate regular
- Moves nutrients into cells
- Has a beneficial effect on blood pressure
In addition to smoking, physical inactivity and other factors, a diet too high in sodium (a component of table salt) can cause high blood pressure. When a person has high blood pressure (hypertension), their body has to exert more force to move blood through the arteries, sometimes leading to complications such as heart disease, stroke, or kidney disease.
Potassium can help the body eliminate sodium through urine and also relaxes blood vessel walls. Together, these elements can help lower blood pressure.
Many studies have shown that consuming more potassium is linked to a reduction in blood pressure in some people.
Research on hypertension and bananas in particular is a bit more limited. However, in 2024, researchers found that eating more apples and bananas reduced the risk of mortality in people with high blood pressure. Additionally, a study done on rats concluded that bananas could limit the effects of hypertension and diabetes.
Increasing your potassium intake, whether with bananas or other potassium-rich foods or supplements, can improve your health beyond just controlling blood pressure. Some additional benefits include:
- Reduced risk of stroke: Studies show that increased potassium intake is associated with a lower risk of stroke and other health problems related to cardiovascular disease.
- Lower risk of kidney stones: Higher potassium intake has been linked to a lower risk of developing kidney stones.
- Improved bone density: Eating more potassium can help increase bone mineral density. This helps your bones stay strong, reducing the risk of osteoporosis and increasing longevity.
- Reduced risk of type 2 diabetes: Potassium helps create insulin, a hormone that regulates blood sugar. Studies have shown that people who consume more potassium have a lower risk of developing type 2 diabetes, although more research is needed.
- Reduced inflammation: Although not generally considered an anti-inflammatory food, bananas may help reduce inflammation, according to some research. Chronic inflammation is a risk factor for other health problems, including diabetes, arthritis and heart disease.
