Are Humans Designed to Eat Meat?

I was raised believing that humans have always eaten meat. We’re not completely carnivores, but we’re omnivores, at least, right? What’s the truth? I like to rely on anthropology and common sense to cut through the 21st-century crap we often tell ourselves and recently I came across a very compelling set of facts that did just that.

The teeth of a carnivore are long and pointed, for tearing. Ours are blunt and flat by comparison. We would find it nearly impossible to tear into a freshly dead animal and eat it raw with our stubby, little, square teeth. Herbivores have small “canine” teeth for biting into tough fruit (like apples) but these are nothing compared to the size and shape of a carnivore’s teeth. Even more telling, carnivores don’t have flat teeth at all. No molars.

The jaws of carnivores move up and down, but not side-to-side. This is because they tear at flesh and swallow it whole. Their stomachs have enzymes (that we do not) that break down the meat. An herbivore’s jaws move up and down AND side-to-side for grinding vegetation. Check your jaws and see what they do.

The intestines of carnivores are very short and simple, three to six times their body’s length, so that they can pass meat through their body quickly and efficiently without absorbing too much cholesterol or saturated fat. This is why it is impossible for carnivores and omnivores eating a natural diet to get most kinds of cancer or heart disease from clogged arteries.

An herbivore’s intestines are long and complex, eight-to-13 times their body’s length. The main contributor to heart disease in humans is saturated fat and cholesterol absorbed from meat and dairy and it lingers for long periods of time in our intestines.

A carnivore can eat rotting, bacteria-ridden meat completely raw without getting sick. They have stomach acids that kill the bad stuff off and enable them to digest what’s left without puking their guts up. Ever try to eat road kill? Or even a freshly dead chicken, completely raw? Give it a shot and let me know how it works out for you. (TIP: Have an ambulance standing by.)

A carnivore is quick, cunning and without sympathy so that it can catch and kill other animals efficiently and without remorse. For the vast majority of human history we have been without tools, weapons or fire. During this period, how many animals do you suppose we successfully caught, ate, and kept down? Try to catch an animal (that doesn’t want to be caught) with your bare hands and you’ll get an idea of how slow we are. Ever feel sorry for an injured puppy? An instinct like that would completely ruin a carnivore’s lunch.

Natural meat-eaters find the sight and smell of dead animals appetizing. How do you feel when you come across a dead rat in your garage?

Here’s a test you can try at home: put a two-year-old in a playpen with an apple and a rabbit. If it plays with the apple and eats the rabbit, you’ve got a carnivore.

According to numerous studies, including the Framingham Heart Study, the longest-running clinical study in medical history, vegetarians have 60% less cancer than meat-eaters, and a tiny fraction of the heart attack rate.

It doesn’t take a rocket scientist to figure out we aren’t very well designed to eat meat.
