Sweet potatoes generally share the same cylindrical shape with tapered ends, but they can vary in size, measuring up to 12 inches long and weighing up to about one pound. Orange-fleshed varieties are soft and moist. Sweet potatoes offer a sugary-sweet flavor with earthy undertones and hints of nuttiness, with some varieties being sweeter than others.
Sweet potatoes rank as one of the healthiest vegetables because of their high levels of vitamin A, C, iron, potassium, and fiber. The orange-fleshed varieties are also an excellent source of the vitamin A precursor, beta-carotene, which our bodies turn into vitamin A. Sweet potatoes are packed with complex carbs, which the body uses for energy, and they also offer antioxidants, which are three times more concentrated in the skin than the flesh.
