Banana peels, also sometimes known as banana skin, are not poisonous to humans and actually contain a number of healthy nutrients that are vital to the body. However, a person needs to wash the peels to get rid of pesticide residue before eating them.
Banana peels have more fiber than the flesh and also contain potassium. Fiber plays a vital role in improving bowel movements and digestion and helps in lowering cholesterol levels in the blood. Additionally, banana peels contain lutein, which is crucial for the health of the eyes, as well as tryptophan, which helps boost a person's mood.
