Yes, the native society thing is a good thing to consider. Jillian Michaels has a radio show, she interviewed a doctor Gunding who has a book out, it sounded very interesting. All I caught was him talking about how eating fruit out of season is not good. Rarely does somebody of his calibre write a book about nutrition, he is a heart surgeon who saw alternative medicine cure a patient so he got interested. He goes into gene switching by diet and I don't know what all, I earmarked his book at amazon...
