Have you read Nora Gedgauda's book Primal Body Primal Mind? I don't agree with loads of meat eating and neither does she- it affects cancer growth according to her research, I eat at most a few ounces and that's a few times per week. I eat eggs (2 at most) a few times per week and fish too (again a few times per week). So the majority of my diet is vegetables- I've always advocated that. I also drink wheatgrass juice and a green drink daily, eat fermented vegetables and coconut kefir. When I do meat it's in a stew, stir fry or lightly seared. One steak feeds my entire family. A little goes a long way. The longest lived cultures on the planet presently eat a plant based diet with supplemental animal food. That says a lot to me.
