I have a problem with the Weston Price Foundation, same problem I have with Paleo 2.0. Too many differences from the modern lifestyle to be certain just why they work. Kurt Harris stayed paleo just long enough to talk about paleo re-enactment not being the goal--I think it is the goal. Is it the lectins, is it the gluten, is it the fat soluble vitamins, is it the phytic acid, is it the fermentation, is it the.. McDonald's is just a sourdough and grass-fed special sauce Big Mac, and beef tallow french fries away from satisfying the Western Price foundation, and sorry, that might be better, but it's still a pretty cruddy diet in my book. I think it's plausible that if I went and lived with the Kitivans (not paleo technically, but...) and lived as they lived, and ate what they ate--then maybe their diet rich in sweet potato and cassava would be good for me. I'd hate to have to start smoking, though.
