Banana Benefit #4: Boost Heart Health
Sodium also negatively affects the heart. Boosting potassium while reducing sodium is probably the single most important change you can make to reduce your risk of cardiovascular disease.
One study has indicated that people who take in at least 4,069mg of potassium per day have a staggering 49% lower risk of death from ischemic heart disease than those who consume less than 1,000mg. Bananas boost heart health in other ways, too: the fiber, vitamin C, and B6 in bananas are all critical to a strong heart.
