…eat it once baked. Delicata, acorn and sweet dumpling squashes have softer skins, while some squash skins such as spaghetti squash and pumpkin are tougher and difficult to digest, even when cooked.
Mango: Researchers found that mango skin contains properties similar to resveratrol, which helps burn fat and inhibits the production of mature fat cells. Mango flesh extracts were also tested, but did not produce the same results, which suggests that one needs to eat mango skin in order to get this beneficial property.
A mango’s peel also contains larger quantities of carotenoids, polyphenols, omega-3, omega-6 and polyunsaturated fatty acids than its flesh. Another study found compounds more heavily concentrated in mango’s skin that fight off cancer, diabetes and heart disease. Mango skin also has quercetin.
Honorable mention:
Pineapple Core
Okay, so this point is not technically a skin, but a pineapple core it is important to add, as the core contains the highest concentration of bromelian. Keep in mind due to the blood thinning properties of bromelian, you should also avoid taking aspirin (or any other medicinal blood thinners) if consuming pineapple on a daily basis.
On a side note here, the bromelian content is very minimal in canned pineapple. In most canned pineapple the core is removed before the canning process and even if it isn’t, the heating process for canning actually destroys the bromelian content.
