Carrots and cabbage are, I think, of european origin. 'Taters and 'maters, and corn (Zea maize)are all of american origin. I thought it a little strange to see the hobbits fleeing through field of maize. The "time feel" of the film works is medieval, or pre-Colombian, which is why I was sort of suprised to see american food stuffs. Guess that's the beauty of fantasy and wizardry.
