What an interesting thought. I was reading the info from an african-american and wondered what all the different nationalities were and if there was any that was more representative than another one. I am German-from Russia mennonite from the Black Sea area on my fathers side and English from my mother's side. I had an old DO doctor tell me one time that we are a result of what our ancestors ate. I can trace my ancient ancestors back to the Netherlands at about the time the ice age was getting over. What did they eat? You would probably need to know where all they migrated to and what they ate from ancient times to now. I can see this would get a bit complicated but interesting.
