The black ripe fruit that you think is just for throwing away is actually a nutritional "treasure"

Bananas are a popular fruit in our country and bring many health benefits, but if bananas are left for too long, many black spots will appear. Many people think that if bananas have black spots, they will have to be thrown away.

However, if the banana peel is only black and mottled on the outside and the flesh inside remains the same color, you can eat it with complete confidence. According to research by Japanese scientists , the black spots on this fruit have some health benefits.

Bananas ripen to the point where black spots appear on the skin, which increases antioxidants and makes nutrients more easily absorbed into the body.
