>The plain fact of the matter is that humans evolved on an almost exclusively meat-based diet At one point in our evolutionary chain (that of Homo erectus and early Homo sapiens), sure. At other points (Australopithecus) we were exclusively vegetarian. For much of our history (that of Homo habilis and more recent Homo sapiens) we've eaten significant amounts of both plants and animals. I'd love to see a source for the claim that plants are toxic for humans. Considering that many humans eat exclusively plants, and that those people seem to have lower all-cause mortality rates than people with otherwise similar characteristics [0], I suspect that that could only be true if you're using a very non-standard definition of "toxic."
