Sweetpotato is one of the world’s most important food crops in terms of human consumption, particularly in Sub-Saharan Africa, parts of Asia, and the Pacific Islands. Many parts of the plant are edible, including leaves, roots, and vines, and varieties exist with a wide range of skin and flesh color, from white to yellow-orange and deep purple. Orange-fleshed sweetpotato is an important source of beta-carotene, the precursor to Vitamin A. Just 125g of fresh sweetpotato roots from most orange-fleshed varieties contain enough beta-carotene to provide the daily pro-vitamin A needs of a preschooler. Sweetpotato is also a valuable source of vitamins B, C, and E, and it contains moderate levels of iron and zinc.
