We all know that bananas are chock full of potassium, which helps regulate blood pressure and reduce risk of stroke. But researchers in Taiwan “discovered that banana peel is rich in serotonin, which is vital to balancing moods” and warding off depression.

Plus, the researchers also learned that banana peels contain lutein, an antioxidant that provides nutritional support for healthy eyes and may even regenerate retina cells.

So how do you eat a banana peel? says: “Boil the skin for 10 minutes then drink the liquid once cooled, or put through a juicer”. The team of researchers say you should drink banana peel water a few times a week.
