8 Ways a Daily Banana Supports Health After 50
1. Blood Pressure May Improve
Potassium is one of the most important minerals for regulating blood pressure—and bananas are famous for it. One medium banana provides about 12% of your daily potassium needs.
Why it matters after 50: Blood pressure tends to rise with age due to stiffening arteries and changes in kidney function. Adequate potassium helps counterbalance sodium and relax blood vessel walls.
The research: Studies show that higher potassium intake is associated with lower blood pressure and reduced risk of stroke, particularly in older adults.
