Why eat sweet potatoes?

The deep orange-yellow color of sweet potatoes tells you that they're high in the antioxidant beta carotene. Food sources of beta carotene, which your body converts to vitamin A, may help slow the aging process and reduce the risk of some cancers. Sweet potatoes are also good sources of fiber, vitamins B-6, C and E, folate and potassium. They're fat-free and low in calorie density, meaning you can have a larger portion size without racking up the calories.
