"The tomato is native to South America. Genetic evidence shows the progenitors of tomatoes were herbaceous green plants with small green fruit and a center of diversity in the highlands of Peru.[2][3] One species, Solanum lycopersicum, was transported to Mexico, where it was grown and consumed by Mesoamerican civilizations. The exact date of domestication is not known. The first domesticated tomato may have been a little yellow fruit, similar in size to a cherry tomato, grown by the Aztecs of Central Mexico.[4][unreliable source?] The word "tomato" comes from the Nahuatl word tomatl, literally "the swelling fruit".[5]
Spanish explorer Cortés may have been the first to transfer the small yellow tomato to Europe after he captured the Aztec city of Tenochtítlan, now Mexico City, in 1521, although Christopher Columbus, a Genoese working for the Spanish monarchy, may have taken them back as early as 1493. The earliest discussion of the tomato in European literature appeared in an herbal written in 1544 by Pietro Andrea Mattioli, an Italian physician and botanist, who named it pomo doro, or "golden apple".[3]:13
The earliest reference to tomatoes being grown in British North America is from 1710, when herbalist William Salmon reported seeing them in what is today South Carolina.[3]:25 They may have been introduced from the Caribbean. By the mid-18th century, they were cultivated on some Carolina plantations, and probably in other parts of the Southeast as well. Possibly, some people continued to think tomatoes were poisonous at this time; and in general, they were grown more as ornamental plants than as food. Thomas Jefferson, who ate tomatoes in Paris, sent some seeds back to America."

"The cacao tree is native to the Americas. It may have originated in the foothills of the Andes in the
Amazon and Orinoco basins of South America, current day Venezuela, where today, examples of wild cacao still can be found. However, it may have had a larger range in the past, evidence for which may be obscured because of its cultivation in these areas long before, as well as after, the Spanish arrived. It was first cultivated by the Olmecs at least 1500 BC in Central America."
Keep in mind that the Americas is not the same as "America". Both these items were more likely to be propogated by the Mayans then the Indians of the US.
Just sayin! No offense intended
