Sweet potato is one of the oldest vegetables consumed to this day, believed to be in consumption more than 5000 years ago. In fact, related artifacts have been seen in Peruvian caves dating back more than 8000 B.C and serve as the best proof of their consumption even in prehistoric times. Sweet potatoes has been a great part of the American diet for most of America’s history particularly in the Southeast, where it is know as yams.
However This nutritious tuber is no relations to true yams. True yams have brown or black skin which resembles the bark of a tree and off-white, purple or red flesh, depending on the variety. The flesh of yams are starchier and drier than that of the sweet potato. In fact the name yams came about when African slaves seeing the tuber, being reminded of the yams of their homeland called it “nyami”. The Senegalese word “nyami” was eventually shortened to the word “yam”.
