Humans have evolved on an omnivorous diet. The evolution-from-meat-eating myth has been debunked many times over. Compared to an actual carnivore, our digestion is more akin to a herbivore than a carnivore. Just because we can eat meat, does not mean we should.

Edit: Not even to speak of the fact that most meats the average person eats are stuffed full of antibiotics, so eating those does not equate a healthy diet.
