Tomatoes, chocolate, vanilla, corn, alot of beans, alot of squash (including pumpkins), cotton, sunflowers, potatoes, a host of different kinds of berries. Were all found or originated from the Americas and spread around the world because of humans. Medical research also takes a lot of ingredients from nature as well. If you asked a pothead where weed originally came from they probably couldn't give you the correct geographic region (central Asia) because it is so widespread now that its native range and origin has become ambiguous and also probably because they're a pothead.
