Potatoes, Sweet and Yams

Sweet potatoes and yams are similar in many ways, but they are from different plant species. Sweet potatoes are often called yams. True yams, which are not widely marketed and are seldom grown in the U.S., are similar in size and shape. Yams contain more natural sugar and have a higher moisture content. Sweet potatoes are richer in vitamins A and C.
