The sweet potato is a complex carbohydrate that provides twice the recommended daily allowance of vitamin A and more than one-third of the requirements for vitamin C. They are a substantial source of dietary fiber, especially when eaten with the skin. There is more fiber in one sweet potato than in a bowl of oatmeal. The sweet potato is also an important source of vitamin B6, iron, potassium and fiber. Sweet potatoes contain virtually no fat and are low in sodium.
