Here is a snippet (and link to full article) on recent findings that suggest early corn farmers in current-day Moab, Utah may have eaten cacao (Theobroma cacao) that would have arrived to the American southwest though trade routes established by humans migrating north from Mexico… But the possibility remains that the caffeine and theobromine residuum analyzed from “non-local” ancestral ceramic bowls could have come from a holly (Ilex) species….

Ancient farmers may have nibbled chocolate

Ancient corn farmers living in pit houses among arid canyons of what is now Utah may have sweetened their lives with a chocolate derivative imported from the tropics of Central America, recent archeological findings suggest.
An archeologist and team of chemists analyzing the remains of an eighth century village near present-day Moab found theobromine and caffeine, compounds found in a cacao tree native to Central America and from which chocolate is derived.
“We associate cacao use with the migration of corn farmers from Mexico into the Southwest,” University of Pennsylvania archeologist Dorothy Washburn said on Friday.
