More important than teeth, the human intestinal tract is not designed for digesting meat.

Human teeth like those of the herbivorous creatures are designed for grinding and chewing plant food. Humans lack the sharp front teeth for tearing flesh, that are characteristic of carnivores. Meat eating animals generally swallow their food without chewing it and therefore do not require molars or a jaw capable of moving sideways.
Once within the stomach meat requires digestive juices high in hydrochloric acid. The stomachs of humans and herbivores produces acid less than one twentieth the strength of that found un carnivores. Another crucial difference between the meat eater and the vegetarian is found in the intestinal tract, where the food is further digested and nutrients are passed into the blood.
A piece of meat is just part of a corpse, and its putrefaction creates poisonous wastes within the body, therefore meat must be quickly eliminated. For this purpose, carnivores posses alimentary canals only three times the length of their bodies. Since man like other non flesh eating animals has an alimentary canal twelve times his body length, rapidly decaying flesh is retained for a much longer time, producing a number of undesirable toxic effects. One body organ adversely affected by these toxins is the kidney. This vital organ, extracts waste from the blood, and is greatly strained by the overload of poisons introduced by the meat consumption, and as one grows older this vital organ will not be able to cope with this stress, and the risk of kidney disease and failure increases.

The final point I would like to make on how we as humans were not meant to eat meat is this. All omnivorous and carnivorous animals eat their meat raw. When a lion kills an herbivore for food, it tears right into the stomach area to eat the organs that are filled with blood (nutrients). While eating the stomach, liver, intestine, etc., the lion laps the blood in the process of eating the dead animals flesh. Even bears that are omnivores eat salmon raw. However, eating raw or bloody meat disgust us as humans. Therefore, we must cook it and season it to buffer the taste of flesh.
If a deer is burned in a forest fire, a carnivorous animal will NOT eat its flesh. Even circus lions have to be feed raw meat so that they will not starve to death. If humans were truly meant to eat meat, then we would eat all of our meat raw and bloody. The thought of eating such meat makes one’s stomach turn. This is my point on how we as humans are conditioned to believe that animal flesh is good for us and that we were meant to consume it for survival and health purposes. If we are true carnivores or omnivores, cooking our meat and seasoning it with salt, ketchup, or tabasco sauce would disguise and we as humans would refuse to eat our meat in this form.
