Why The Mix-Up?

The mix-up between yams and sweet potatoes originated from the Trans-Atlantic slave trade. In the Americas, where yams were not readily available, sweet potatoes, which had traveled from Central America with Christopher Columbus, took their place. Sweet potatoes became one of several transfer foods, allowing enslaved peoples to preserve their traditions and spiritual practices even in the face of captivity and abuse.

The yam and sweet potato confusion was further complicated due to a marketing campaign. To distinguish a new variety of sweet potatoes from their East Coast counterparts, the Louisiana sweet potato industry started using the term “yam.”

 

The Verdict

Yams and sweet potatoes are not the same and we should stop interchanging them and start correcting others. Share the knowledge!
