Sweet potatoes add good taste, a splash of color and a slew of important nutrients to your dinner table. Each 3.5 oz. serving supplies twice your daily requirement of vitamin A, 42 percent of your daily vitamin C requirement, 8 percent of your daily thiamine requirement and calcium, iron and fiber. When you cook sweet potatoes after peeling, prevent the loss of essential nutrients, especially the water soluble vitamins C and thiamine, by cooking them quickly, using little to no additional liquid.
