It's been shown that grain fed beef contributes to a skewed omega 3 to 6 ratio and that it impairs our ability to absorb nutrients. Factory farms also infuse their livestock and hormones and other questionable chemical concoctions. Paleo dieters are increasingly turning away from these foods, preferring instead to eat "clean" meat. It's for this reason that dairy tends to be vilified in Paleo circles. Most milk comes from grain fed beef and cause the same inflammatory problems as the meat.Exo Slim Cows, it would seem, react just as badly from gluten in grains as humans do. Critics of the Paleo diet complain that the meat-centric approach is completely out of line and other trends, namely the shift to vegetarian diets. Paleo eaters are often seen by vegetarians and vegans as a selfish group that are looking to take society backwards instead of forward. Ancestral health enthusiasts, on the other hand, make the claim that they are in fact charting a course to the future by overturning conventional models of meat production. Paleo eaters tend to avoid factory farmed foods, insteading buying organic and free range meats and eggs from farmer's markets and organic food stores. Moreover, they are also advocates of sustainable, humanitarian farming practices and the promotion of healthy, untainted foods. An animal that got to live its life on a farm grazing in pasture, they argue, is a far cry from the crammed and deplorable conditions found in most factory farms.
