Yes, you can eat mango skin, but many people don’t like the taste. The skin is a good source of roughage, which helps to clean out your digestive tract. But beware, as some people are highly allergic to the skins. If you tend to have food allergies, avoid it.
Mango skin can be eaten, but is generally not recommended. Mango skin contains a chemical in it -- urushiol -- that is similar to the chemical in poison ivy and can cause allergic reactions in some people.
