>>Wally > Milk may be tolerated by some, grains by others >Exactly right. Let me say this: Toleration ain't the same thing as healthfulness. I agree 100%. I was not promoting milk or grains, merely responding to a post about genetic diversity. However, I do think that 100% paleo is likely to be too much for some individuals, and I would prefer to see them err on the side of caution - by only eating those non-paleo foods they can tolerate prepared in a minimalist fashion. From personal experience - I do not do well on most grains (avoiding wheat and corn like the plague), but I do seem to tolerate dairy in small amounts. I see nothing wrong with that -- for *me*.
