Question

【题目】 Bananas are one of the healthiest fruits you can eat, being loaded with protein, fiber, vitamins A, B6, and C, etc. Bananas are delicious on their own as well. But we’re not here today to talk about the banana fruit, but rather its peels. Generally thrown away as waste, banana peels actually bring about different uses.

Starting off with a topical benefit, banana peels are great for relieving the painful itch of bug bites. Science hasn’t figured out why it works, but you can’t argue with results. People who have tried it report that it is really useful.

There are lots of expensive ways to whiten teeth, and a lot of them use bleaching agents which weaken teeth and can cause sensitivity. But guess what? Banana peels can whiten teeth naturally and gently due to their potassium content.

Banana peels contain a lot of antioxidants that are great for your skin. To reduce the look of lines and wrinkles, simply rub a banana peel directly on the affected areas and wash your face 30 minutes later.

It is fiber once again that can lower your cholesterol levels, which is critical to maintaining a healthy heart. Banana peels contain more soluble fiber than the fruit itself, so throwing away the peel wastes a valuable opportunity to bump your intake. And finally, you can actually rub a banana peel on shoes, leather, and silver articles to clean them up and make them shine.

Whether you eat them or use them, banana peels don’t save very well. Once removed from the fruit, they blacken pretty quickly. It's best to prepare and consume banana peels right away. However, one thing is for sure—you will stop throwing these valuable wrappers in the trash after you discover all the incredible things they can do.
