I used to think we were not meant to eat meat.
But I think of the fact that a vegetarian could eat a piece of meat and become sick simply because their body does not have the active enzymes to digest the meat properly. A person who actively eats meat, their system takes it down and digests it accordingly.
Just a simple fact like that leads me to believe that humans are omnivorous and adapative to 'what's on the plate' (so to speak.)
I think being vegan is a lot more healthy long term, but that doesnt mean we are supposed to eat that way IMO.
That sounds very evolutionary err I mean revolutionary...we adapt to our environment very well, I watched a documentary about a group in Africa that doesn't drink water...because there isn't enough to be had...they get there water from Goats Milk...
