The heart relies on a steady balance of electrolytes to maintain a consistent rhythm. Potassium plays a central role in this process, helping regulate the electrical signals that keep the heart beating properly.
Bananas also contain small amounts of magnesium, another mineral that supports healthy blood vessels and circulation. Together, potassium and magnesium help promote smooth muscle function within blood vessel walls.
The American Heart Association notes that diets emphasizing fruits and vegetables rich in potassium are associated with a lower risk of heart-related concerns. Bananas are also naturally low in fat, contain no cholesterol, and require no processing, making them a heart-friendly alternative to many packaged snacks.
For adults over 50, replacing sugary or salty snacks with a banana can be a small step toward supporting long-term cardiovascular wellness.
