Many parts of foods people eat every day end up being thrown away or composted. However, you might be surprised to find that foods like kiwi skins, banana peels, and watermelon rinds are safe — and even beneficial — to eat. Mango peels and pineapple cores are a great source of vitamin C and orange and lemon peels can also be zested to add flavor to dishes (not really a surprise if you watch the food networks)!
Mango peels are a great source of vitamin A, vitamin C, fiber, and phytonutrients. While most people simply eat the juicy mango flesh inside, mango peels have a number of health benefits, including a healthy dose of fiber, vitamins, and minerals. According to health authorities, one test-tube study found that mango skin extract exhibited stronger antioxidant and anticancer properties than mango flesh extract. However, mango skin can also cause an allergic reaction for some people, pose a risk of pesticides if not properly washed, and is generally less pleasant to eat texture-wise than the inside of a mango.
