Do Mango Peels Have Health Benefits?

Mango, a tropical fruit with an exotic flavour, is widely known for the health benefits it offers. Not many are aware of the health benefits of mango peel, which is usually thrown away by people.

According to a study, fresh mango contains around 15-20 per cent of peel. Also, polyphenols in the peel are greater in numbers than they are in the pulp. [1]

As mango peel is a by-product of the fruit and is also rich in phenols like pectin, it can highly impact the environment and increase pollution levels. This is the reason why most of the mango peel is used for animal feeding and the rest is used by industries to produce functional foods like juice, vinegar and wine.

In this article, we will discuss some of the uses and health benefits of mango peel. Take a look.
