Answer 2

According to health experts, what we throw away by peeling is actually one of the healthiest parts of our foods.
peels are packed with the good stuff, like antioxidants, vitamins, and fiber
When you strip the skins, you’re cutting out extra essential nutrients that fight disease and keep your body humming along smoothly
Fruit and vegetable peels are rich in several nutrients, including fiber, vitamins, minerals and antioxidants. Consuming the peel with the pulp can boost your total intake of these nutrients.
