Why You Should Avoid Eating Mango Skin

Mangoes are usually peeled, but the skin, it turns out, is perfectly edible and packed with nutrients. That, however, does not mean that it should be eaten.

Mangoes are sprayed with pesticides that may linger on the skin. Eating the skin means that you're likely also eating these pesticides.

These pesticides can have harmful effects on your health, including poisoning, cancer, and issues related to reproduction (via the World Health Organization).

Mango skins can also cause allergic reactions, as they have the same chemical that poison oak and ivy do, aka urushiol, which can cause swelling and leave rashes.
