10. Sweet Potatoes
Sweet potatoes may have calorie counts and traditional nutrients similar to their white potato cousins, but their bright-orange flesh means they pack in a lot of antioxidants in the form of beneficial beta-carotene. A medium sweet potato has about 115 calories and is a good source of vitamin C, fiber and potassium, but it also has more than a day’s worth of vitamin A (as beta-carotene). Sweet potatoes improve your skin’s health by increasing its ability to protect against the sun’s harmful ultraviolet (UV) rays. In addition, the beta-carotene and other carotenoids present in the orange flesh have known anticancer properties. In a study of more than 7,000 women, researchers found that those with the highest blood levels of carotenoids had significantly reduced risk for breast cancer.
