> Though, there are plenty of counter examples of cultures that have an almost all meat diet and are perfectly healthy, there are other factors involved in those cultures that don't apply to your average first world eater -- the meat is mostly wild caught for instance. The more obvious and probably more important factor, that doesn't apply to the average first world eater is there are very few of those that have a diet consisting predominantly of meat. Most meat eaters today still have significant portion of their calories coming from refined carbs and they usually avoid fatty meat, which is a staple for those cultures you mentioned.
