“All the Nutrients Are in the Skin of the Potato”
Ayoob: There are nutrients and fiber in the skin. That’s true of fruit skins, too, like apple peels. Wherever the color is, that’s where most of the antioxidants, minerals, and good nutrition are.
Gans: The skin contains fiber, but the flesh is important, too. It’s loaded with potassium, magnesium, vitamin C, and folate. So eating the whole package is the way to go.
Tallmadge: Not all the nutrients are in the skin, but some of them are. Ounce for ounce, the skin is definitely superior to the flesh, since it contains more calcium, iron, and fiber. That’s why I tell people to scrub the skin and eat it along with the rest of the potato.
