Well, I was going to talk about our non-cellulose digesting stomach but Snerp beat me to the punch.
Consider the appendix though. It's much enlarged in true herbivores, to aid in digestion. In humans, it has evolved to get smaller and smaller, to the point where it gets plugged up. If we were true herbivores, why would it evolution try to oust it, basically putting us in danger in the process?
Sorry if I don't agree, I'm just part of the humans-are-evolved apes faction.
