Pecans are one in a short list of foods rich in vitamin E, a nutrient that's vital to skin health. By forming a protective barrier in the cell membranes of your skin, the vitamin E in pecans helps to ward off harmful free radicals and therefore helps to keep skin firm and elastic. Toasting pecans makes them incredibly buttery and rich — they're like candy! Spread pecans on an ungreased baking sheet and toast them in a preheated 350° oven (or a toaster oven) for about 5 to 10 minutes (watch them closely to make sure they don't burn). Enjoy them whole as a scrumptious snack, or chop them up and sprinkle them into oatmeal or low-fat yogurt.
