Man is considered to be an omnivore

Man is considered to be an omnivore. But on a scale ranging from carnivores to herbivores, man is biologically much closer to herbivores than it is to carnivores. Humans do not have carnivorous teeth for crushing bones or tearing flesh. 20 of our 32 teeth are meant for chewing.
Another important difference is the length of the intestinal tract. The human intestinal trace is long (six times the length of the body) so it cannot eliminate meat quickly. Decaying meat releases toxins like uric acid, urea and ammonia that pass through the intestinal wall. These toxins affect the joints, cause inflammation, rheumatism, arthritis and cause damage to the kidneys to the liver. Thus, it is advised to rely majorly on a plant based diet along with consuming meat in small portions.
