    • The yam they are talking about are the ones that are true yams that are grown and found in South Africa. Rarely do you see one in the United States. The true yam also has a tougher exterior, versus the thinner skinned orange, white, and apparently purple sweet potatoes found frequently in the supermarket in the United States.
