VITAMIN A. When eaten with the skin on, one medium sweet potato contains over 100% of the recommended daily amount of vitamin A, which plays a role in vision, bone development and immune function.
FIBER. Sweet potatoes are a good source of fiber, which can contribute to feelings of satiety, or feeling “full” and can aid in digestion, by helping to help keep you regular. Diets rich in foods containing fiber, such as some vegetables and fruits, may reduce the risk of heart disease, and some types of cancer (a disease associated with many factors).
POTASSIUM. Sweet potatoes contain potassium. Diets containing foods that are a good source of potassium and that are low in sodium may reduce the risk of high blood pressure and stroke.
CARBOHYDRATES. Sweet potatoes are made of complex carbohydrates that are released at a steady pace for a constant source of energy, so no sugar highs or lows to worry about.
