What food was exchanged between the new world and the old world?

The Columbian Exchange facilitated the transfer of various foods between the New World and the Old World. The New World introduced crops such as maize (corn), potatoes, tomatoes, and cacao to Europe, Africa, and Asia. In return, the Old World brought wheat, rice, sugarcane, and coffee to the Americas. This exchange significantly impacted diets and agricultural practices across both regions.
