Are humans omnivores, herbivores or frugivores?
Many people say humans are naturally omnivores but is that really the truth? What about herbivores--are we supposed to be mainly plant eaters by our design? Looking at the chart below, our anatomy suggests something else. Our teeth resembles neither omnivores or herbivores but frugivores, that is we don't have sharp teeth like carnivores, nor do we have flat teeth like herbivores. Our intestines are the same length as a frugivores as well, a design optimal for digesting fruits, nuts and vegetables. Carnivores and omnivores have much shorter intestines because the meat they eat turns toxic and is required to be dumped quickly from the body. Another argument I've heard that claims we are supposed to be omnivores is because we need vitamin b12. The claim is that we need to eat meat in order to obtain b12, thus proving we are meant to be omnivores. But upon researching the subject, I found that even the animals we eat don't produce the B12 naturally. The farmers in fact supplement the grain they feed to the cows with b12 so the livestock get the nutrients needed to be healthy. Humans who consume this meat are thus indirectly obtaining a supplement of b12. Vegans/Vegetarians don't get b12 in this way and thus need to eat fortified foods or buy the supplements themselves.
So in conclusion, I have to say that our bodies are naturally meant to be frugivores, ie what we are designed to eat to maintain optimal health are plants, fruits and nuts. What do you guys think?
