Want a healthier alternative to potatoes? Sweet potatoes are high in vitamin A and a host of other cancer-fighting compounds. They're also full of fiber and iron that give you energy and keep your digestive tract healthy. Plus, they taste a lot better than the Idaho variety. These orange beauties make great home-made potato chips. Slice them thin and roast them in the oven until they are brown. Then dust them with salt and your favorite chip topping.
