Yes, mango skin is edible, and some people eat mangoes whole, like apples. But there are good reasons most people peel them, and for some people the skin can cause an allergic reaction.
What is in mango skin
Mango skin contains fiber and plant compounds such as polyphenols and carotenoids, as well as mangiferin, an antioxidant that is being studied in laboratories. Some studies suggest the peel contains higher concentrations of some of these compounds than the flesh. That does not mean eating it has proven health benefits: the flesh is already a good source of vitamin C, vitamin A and fiber.
The urushiol problem
Mangoes belong to the same plant family as poison ivy, poison oak and poison sumac. Their skin, stem and sap contain urushiol, the oily compound that causes the poison ivy rash. People who are sensitive to poison ivy can develop itching, redness, swelling or blisters around the mouth after contact with mango skin. This is sometimes called “mango dermatitis”.
If you react to poison ivy, avoid mango skin, and consider having someone else peel the fruit, or wear gloves. Most people with this sensitivity can still eat the peeled flesh. Seek medical help for any swelling of the lips, tongue or throat, or difficulty breathing.
Taste and texture
Mango skin is tough, slightly bitter and can have a resin-like or turpentine flavor, especially in some varieties and in unripe fruit. Many people simply do not enjoy it.
Pesticides
Like other fruit eaten with the skin, mango peel may carry pesticide residues. Wash it well under running water and rub the surface. Organic mangoes are an option if you plan to eat the skin.
If you want to try it
- Choose a ripe mango with a thin skin; some varieties are more pleasant than others.
- Wash it thoroughly.
- Slice it thinly, or blend the skin into a smoothie, where texture and bitterness are less noticeable.
- Try a small amount first, to check for any reaction.
How to cut a mango (without the skin)
Stand the mango on its end, slice off the two “cheeks” on either side of the flat pit, score the flesh in a grid without cutting through the skin, then push the skin inside out and slice off the cubes.
Mango is a great fruit for smoothies and desserts, see homemade drinks and homemade ice cream and sorbet. For other foods people wonder about, see what pepperoni is made of.
