You're corrent, Rapaire. Dogs are also omnivores, and they will eat almost anything that they come across, although not some of the fruits, like citrus. But my point was that humans have teeth which indicates that their main diet should consist of plants, while dogs have teeth that indicate that their main diet should consist of animals.

A dog's teeth are intended to pierce and tear flesh of its prey...but they can be used to eat other foods. A human's teeth are intended to chop and grind plants and fruits, etc....but they can be used to eat other foods.

The difference between a mainly carniverous omnivore's teeth and a human's teeth are dramatic and obvious. The dog's teeth come to sharp points, particularly noticeable in a puppy, a bit less sharp as the dog grows older. A human's teeth do not come to sharp points, although they do possess a single set of small, dull canine teeth. I think it's pretty clear what Nature intended those vestigial canine teeth for: they are there for a last ditch defense, assuming the human gets attacked by a true carnivore, a creature which will be armed with many sharp teeth, not just one set of small and not very formidable canines.

I'm not saying humans shouldn't eat any meat. I'm saying they they have fallen into cultural patterns where they're eating far more of it than is good for their health...or their digestive tract.

They do it because it's fun, it tastes good, they associate it with affluence and success, it's convenient, and they're used to doing it.
