Sweet potatoes are rich in vitamins and minerals. Like most orange-colored vegetables, they're extremely high in vitamin A and potassium, plus they’re an excellent source of calcium, magnesium, vitamin C, fiber and B vitamins.
They’re also high in beta-carotene, which is an anti-oxidant that may help to prevent some types of cancer, asthma and heart disease. They’re also good for women who have diabetes because they’re low on the glycemic index, and the potassium may help lower blood pressure. In addition, all that vitamin A means they’re good for you eyes and skin, too.
Fresh whole sweet potatoes keep for a long time as long as you keep them in a dark and cool part of your kitchen. Bake them in the oven or prepare them in the microwave oven and serve with a little salt, pepper and your favorite seasonings. Or you can buy canned or frozen sweet potatoes that simply need to be heated and served.
