Sweet potatoes

Sweet potatoes are a good source of beta carotene, a nutrient found in plants that works as a provitamin A, so it may be turned into vitamin A in the body. One 1/2-cup (100-gram) serving of sweet potatoes provides more than six times the daily value of vitamin A.

Beta carotene and other carotenoids work as natural sunblocks, which help to keep your skin healthy. When this antioxidant is consumed, it is absorbed into your skin and helps to protect your skin cells from the sun. This may aid in the prevention of sunburn, cell death, and wrinkled, dry skin. Sweet potatoes are also high in vitamin C and vitamin E, which are both essential for maintaining healthy, supple skin. Vitamin C aids in the production of collagen, which tightens the skin. Sweet potato's antioxidants are also responsible for a natural sheen.
