Bananas and Blood Pressure: A Modest Heart-Healthy Boost
Bananas can help lower blood pressure because they’re rich in potassium, which helps the kidneys remove excess sodium, reduce fluid retention, and relax blood vessel walls. The BP drop after eating one banana is modest, and benefits don’t compound with more fruit—one banana a day is typically enough and increasing intake could raise potassium to unsafe levels for people on certain medications or with kidney disease. Regular banana consumption also supports heart health through fiber and magnesium, but medications and broader lifestyle changes remain important for blood pressure management.
