7. Lower Cholesterol
It is fiber once again that can lower your cholesterol levels, which is critical to maintaining a healthy heart. Banana peel contains more soluble fiber than the fruit itself, so throwing away the peel wastes a valuable opportunity to bump your intake.
Soluble fiber reduces the absorption of cholesterol into your blood stream by binding with it in your intestines. Therefore, the cholesterol passes out of your body in waste rather than stays behind to clog up your arteries.
