If you live in the U.S., you’re probably used to throwing banana peel into the trash. But people in other countries, including India, have been taking advantages of their nutritional benefits for many years.

While the flesh of a banana is soft and sweet, the skin is thick, hard and slightly bitter. To eat the peel, you can fry, bake, or boil it for at least 10 minutes. Also, the riper bananas get, the thinner and sweeter banana peel will become. That’s because of a natural plant hormone(激素) called ethylene(乙烯) that fruits release as they ripen. Ethylene interacts with the sugars and fiber in the banana skin, changing complex sugars into simple sugars and breaking down pectin, a form of fiber in bananas that keeps them stiff. That’s why the older your banana is, the flimsier(不结实的) it feels.

The sweet flesh of a medium-sized banana contains great percentages of your daily recommended intake of various nutrients, such as:

·12% of your daily fiber, which helps with digestion and may help lower your risk of diabetes(糖尿病)

·17% of your vitamin C, which is important for your immune system as well as your growth

·20% of your vitamin B6, which aids the body’s ability to turn food into energy

·12% of your potassium, which helps with the development of cells, tissues, and organs throughout the body

If you eat the skin along with the flesh, you will get an even bigger increase in these same nutrients.

Eating the peel is not only good for your body but also better for the earth. The average American ate 11.4 pounds of bananas in 2014. Since a medium-sized banana weighs about 0.3 pounds, that equates to about 38 bananas per person, or about 12 billion for the whole of the U.S. And since most of us throw away the peel, that also means a lot of organic waste.
