What about a purple-skinned eggplant or a white-skinned eggplant? Trick question! Remember, the pigment is the antioxidant, so the color of the skin doesn’t matter if you peel it off. As we learned in chapter 11, that’s why you never want to peel apples. It’s for this same reason kumquats may be the healthiest citrus fruit, since you can eat them rind and all.
