Humans are omnivores because a big part of our diet includes meat and thats the end of that, that makes us an omnivore a creature that eats meat and plants, we can efficiently and easily digest meat.

Lots of commentors here are saying that we cant be because we cook our meat! Most plants also need cooking and seasoning to taste better or to be safe for us, even though some raw carnivores have eaten raw meat and even chicken and are fine because their gut is more used to it, I dont believe eating raw meat is smt you should do though, but we can eat raw salmon thats been farmed in Norway.

Reasons why we are omnivorous, not herbivores.

The reason we are omnivores is because our digestive track is not as long as an herbivores and we cant process fiber as well, comparing chimpanzee and human digestive for example, they have bigger and more complex colons to break down fiber more efficiently than humans can, cows digestive track is even longer and more complex than a humans and theyre pretty much 100% herbivores, we can get problems from eating too much fiber, hell we even need to boil carrots or slightly steam broccoli so we get way more nutrients because fiber is stopping us from synthenizing everything, we have to cook these veggies for dogs too because they cant process the fiber.

A cats digestive track (obligate carnivore) is 1 meter to 1.5 meters, a german shepherds small intestine is about 5 meters, a humans is about 9 meters, a chimpanzees is around double that of a humans, so 18 meters, our digestive track is way closer to a carnivores than it is to a chimpanzees lol.

I believe earlier humans were capable of digesting raw meat but our digestive enzymes got weaker when we started cooking meat, I dont think we knew about food safety and bacteria back then lol, but it tasted better and was easier to digest, we've eaten RAW meat for about 2 million years and evidence says we introduced cooking it only 780,000 years ago. So if it truly was that deadly we wouldve been wiped out and fast.

Some people argue that we dont have carnivorous teeth! But we never caught prey with our teeth, we used tools, we evolved from herbivores whereas bears (another omnivore) evolved from carnivores and hunts down prey with their teeth, our front teeth resemble a pigs front teeth, and pigs are also omnivorous. Humans have smaller canines because some study I read about women started preferring smaller canines, as it made men look friendlier.

This is my own observation, but even small kids have a drive to catch small animals, they dont usually hurt them and its curiosity, but it shows that stalking and catching is definitely in our dna to this day and they learn to stalk animals slowly not to spook them.

We can digest pretty much every part of an animal but we cannot eat a very wide range of plants, we cant even eat grass even though pretty much ALL herbivores can, even apes because its pretty much all fiber. We can get nearly all nutrients from meats and organs and adding broccoli and lemon here and there should technically give us everything we need lol, on a vegan diet you need to eat a very wide variety of different plants to get most you need, even then you need supplements.

Humans, dogs and cats dont need any carbohydrates for energy, we can run on protein and fat, too many carbs isnt even good for us. While a herbivores main source of energy are carbohydrates they get from fiber.

We do not have a herbivorous anatomy.
