Why do humans eat meat when their teeth are like a cow?

Question

human teeth grasses,grains,vegetables

cat-dogs etc teeth are sharp.Is that a myth?

Answer 1

human teeth haven't needed to be sharp for a long time, since the dawn of cutlery. it's simply not necessary.humans need meat protein for a healthy balanced diet. it's very hard for a human to get all the vitamins, minerals and nutrients from a completely vegetable based diet. in fact humans are predators, and have eaten meat for a very long time, and have thus evolved to the point where it is almost impossible to cut meat completely out of the diet. the body simply requires it, whether it's from meat or eggs, or milk and cheese.



ps. dogs can be vegetarian, however cats must be carnivorous or they will die.

Answer 2

well, not all of our teeth are like cow's teeth.  like the canines,  i teeth, i have no idea what they are called...

Answer 3

Human teeth are like a cow's, they are closer to pigs which are omnivores. We also don;t have four chambered stomachs like cows. Nor do we have to regurgitate our food and chew it (cud) like a cow. Also, our closest relatives, teh chimpanzee (sharing 98% DNA with humans) are omnivores

I saw a source that may also answer your question. It makes a list, including teeth, as to why we are omnivores. It is also a vegetarian website

quote: "Although evidence on the structure and function of human hands and jaws, behavior, and evolutionary history also either support an omnivorous diet or fail to support strict vegetarianism, the best evidence comes from our teeth.

The short canines in humans are a functional consequence of the enlarged cranium and associated reduction of the size of the jaws. In primates, canines function as both defense weapons and visual threat devices. Interestingly, the primates with the largest canines (gorillas and gelada baboons) both have basically vegetarian diets. In archeological sites, broken human molars are most often confused with broken premolars and molars of pigs, a classic omnivore. On the other hand, some herbivores have well-developed incisors that are often mistaken for those of human teeth when found in archeological excavations"

Answer 4

Humans have digestive systems (from mouth through colon) that have characteristics of both carnivores and herbivores. This makes sense, as we are omnivores.

Humans have teeth for grinding and chewing (plants) and for tearing (meat). Look at your teeth. You can see the pointy ones.

Like carnivores, we have only one stomach. We don't need to eat rocks or regurgitate and re-swallow to get nutrition out of our food.

On the other hand, if you check out the human colon, it's full of wrinkles and folds, like an herbivore's. The carnivore colon is straight and smooth, without the little pockets.

In short, humans are equipped with the anatomical tools to consume both meat and plants. Cats aren't well-equipped to eat plants and cows certainly aren't equipped to be hunters. Humans have the best of both worlds.  

Answer 5

Cows taste better than grass.

Answer 6

Human teeth are designed for meat, fruits, vegetables, grains nuts and seeds. They are effective for an omnivorous diet. The teeth arguments has been used by both "meat eaters" and veg*ns. But in truth it doesn't prove either case. It just means we are able to survive on either an omnivorous or vegetarian diet. The jaw/teeth argument is weak on both sides of the fence any way. There are many more significant reasons to go veg that some evolutionary leap of logic. It's more of a rumor.

Answer 7

Our teeth are like neither the cow nor the cat. One is a herbivore, the other a carnivore. Humans are omnivores, hence the 3 tooth variety combo.

Answer 8

gee why do humans eat vegetables when their eyes are positioned like predators?

Humans have been eating meat for over a million years. If you want to be veg, fine but don't push your psuedoscience on us.

Answer 9

Totally true. Especially when our mouths and bodies were not cut out to eat meat. Very observant of you.

Answer 10

Biologically speaking, humans are omnivores, and no amount of debating will change that.

To answer your question, people eat meat because it provides nutrition and they like the taste of it. There are perhaps other reasons, but I'm not a meat eater so I wouldn't know. Don't forget that in some cultures, they couldn't survive without it. We have the luxury of being able to live healthily without meat in the western world. Not everyone has that opportunity.
