Sweet Potatoes

This super-food is packed full of iron, zinc, copper, calcium, potassium, niacin, and magnesium, as well as vitamins A, B6, C, D, and E. Because all of those components, contribute to healthy and glowing skin, the combination of vitamin C, vitamin E, and beta-carotene makes this potato one heck of a "beauty food".

Beta-carotene is abundant in sweet potatoes. This molecule is converted by the body into vitamin A, which is related to healthy hair. A medium sweet potato (114 grams) has enough beta-carotene to provide four times your daily vitamin A requirements. Vitamin A boosts the production of sebum, which helps to maintain hair healthy, according to research. Furthermore, vitamin A may help to speed up hair growth and encourage the formation of thicker hair, all while avoiding the regress of other hair follicles.
