The sweet potato (Ipomoea batatas) is a dicotyledonous plant that belongs to the morning glory family Convolvulaceae. Its large, starchy, sweet-tasting, tuberous roots are a root vegetable. In some parts of the English-speaking world, sweet potatoes are locally known by other names such as kumara, but people usually confused it with yam due to their similar appearances. The young leaves and shoots are sometimes eaten as greens. The sweet potato is only distantly related to the potato (Solanum tuberosum) and does not belong to the nightshade family Solanaceae, but both families belong to the same taxonomic order, the Solanales.Sweet potatoes contain a wealth of orange-hued carotenoid pigments. In countries throughout Africa, in India and in the Caribbean, sweet potatoes have been shown to be a highly effective way of providing school age children with sizable amounts of their daily vitamin A. In some studies, sweet potatoes have been shown to be a better source of bioavailable beta-carotene than green leafy vegetables. Because sweet potatoes are available in many countries on a virtual year-round basis, their ability to provide us with a key antioxidant like beta-carotene makes them a standout antioxidant food.Sweet potatoes are native to Central and South America and are one of the oldest vegetables known to man. They have been consumed since prehistoric times as evidenced by sweet potato relics dating back 10,000 years that have been discovered in Peruvian caves.
