I basically took bits and pieces from a long article that was written about vegetarianism...the link is here if you are interested in reading it all but for those who want a shorter version, I have taken parts that I found interesting and fascinating and included them... Read it with an open mind! Taken from http://michaelbluejay.com/veg/natural.html
Eating meat isn't natural
Why humans are primarily plant-eaters by designClearly we're capable of eating meat. But that doesn't mean it's natural. You can dress a monkey up in a cute little suit and teach it to perform circus tricks, but just because it can doesn't mean that it's natural -- nor that it should. When I say that meat-eating is unnatural, I mean simply that our bodies aren't optimized to have it be a normal part of our diets -- and we suffer the consequences when we make it so.So I challenge you: stop trying to figure out ways that I "must" be wrong even before you've bothered to read the rest of this article. Instead, read it, and actually consider it rather than reflexively trying to come out with ways to dismiss it out of hand. You can certainly still disagree after you've considered all the evidence -- but not before.
But haven't humans always eaten meat?
John McDougall, perhaps the most knowledgable expert on the relationship between diet and disease, asserts that our early ancestors from at least four million years ago followed diets almost exclusively of plant foods. Many other scientists believe that early humans were largely vegetarian. This is important because while prehistoric peoples hunted animals, that is still a relatively recent development in the long period of human existence. Certainly not long enough for our bodies to have adapted to it from evolution. Here's some evidence: The Maasai in Kenya, who still eat a diet high in wild hunted meats, have the worst life expectancy in the world.
Our closest animal relatives are primates. They provide clues about our ideal diet since our anatomy is so similar. Very few of them eat any significant amount of animals, and those who do typically mostly stick to things like insects, not cows, pigs, and chickens. Jane Goodall, famous for her extensive study of apes while living with them, found that it was very rare for the primates she saw to eat other animals. Critics lunge all over the fact that Goodall discovered that primates occasionally eat meat. But the key word here is occasionally. If we ate meat is infrequently as the other primates did, our health would be a lot better. Goodall herself apparently wasn't impressed by primates' occasional eating of meat: Goodall herself is a vegetarian.
Humans lack a desire to eat whole animals
While carnivores take pleasure in killing animals and eating their raw flesh, any human who killed an animal with his or her bare hands and dug into the raw corpse would be considered deranged. Carnivorous animals are aroused by the scent of blood and the thrill of the chase. Most humans, on the other hand, are revolted by the sight of raw flesh and cannot tolerate hearing the screams of animals being ripped apart and killed. The bloody reality of eating animals is innately repulsive to us, more proof that we were not designed to eat meat.
Ask yourself: When you see dead animals on the side of the road, are you tempted to stop for a snack? Does the sight of a dead bird make you salivate? Do you daydream about killing cows with your bare hands and eating them raw? If you answered "no" to all of these questions, congratulations you're a normal human herbivore, like it or not. Humans were simply not designed to eat meat. Humans lack both the physical characteristics of carnivores and the instinct that drives them to kill animals and devour their raw carcasses.
Comparing humans to other animals
Meat-Eaters Carnivorous animals, including the lion, dog, wolf, cat, etc., have many unique characteristics which set them apart from all other members of the animal kingdom. They all possess a very simple and short digestive system -- only three times the length of their bodies. This is because flesh decays very rapidly, and the products of this decay quickly poison the bloodstream if they remain too long in the body. So a short digestive tract was evolved for rapid expulsion of putrefactive bacteria from decomposing flesh, as well as stomachs with ten times as much hydrochloric acid as non-carnivorous animals (to digest fibrous tissue and bones). Meat-eating animals that hunt in the cool of the night and sleep during the day when it is hot do not need sweat glands to cool their bodies; they therefore do not perspire through their skin, but rather they sweat through their tongues. On the other hand, vegetarian animals, such as the cow, horse, zebra, deer, etc., spend much of their time in the sun gathering their food, and they freely perspire through their skin to cool their bodies. But the most significant difference between the natural meat-eaters and other animals is their teeth. Along with sharp claws, all meat-eaters, since they have to kill mainly with their teeth, possess powerful jaws and pointed, elongated, "canine" teeth to pierce tough hide and to spear and tear flesh. They do NOT have molars (flat, back teeth) which vegetarian animals need for grinding their food. Unlike grains, flesh does not need to be chewed in the mouth to predigest it; it is digested mostly in the stomach and the intestines. A cat, for example, can hardly chew at all.
Plant-Eaters
Grass-and-leaf-eating animals (elephant, cow, sheep, llama, etc.) live on grass, herbs, and other plants, much of which is coarse and bulky. The digestion of this type of food starts in the mouth with the enzyme ptyalin in the saliva. these foods must be chewed well and thoroughly mixed with ptyalin in order to be broken down. For this reason, grass-and-leaf eaters have 24 special "molar" teeth and a slight side-to-side motion to grind their food, as opposed to the exclusively up-and-down motion of carnivores. They have no claws or sharp teeth; they drink by sucking water up into their mouths as opposed to lapping it up with their tongue which all meat eaters do. Since they do not eat rapidly decaying foods like the meat eaters, and since their food can take a longer time to pass through, they have much longer digestive systems -- intestines which are ten times the length of the body. Interestingly, recent studies have shown that a meat diet has an extremely harmful effect on these grass-and-leaf eaters. Dr. William Collins, a scientist in the New York Maimonedes Medical Center, found that the meat-eating animals have an "almost unlimited capacity to handle saturated fats and cholesterol". If a half pound of animal fat is added daily over a long period of time to a rabbit's diet, after two month his blood vessels become caked with fat and the serious disease called atheriosclerosis develops. human digestive systems, like the rabbit's, are also not designed to digest meat, and they become diseased the more they eat it, as we will later see.
Fruit-eaters include mainly the anthropoid apes, humanity's immediate animal ancestors. The diet of these apes consists mostly of fruit and nuts. Their skin has millions of pores for sweating, and they also have molars to grind and chew their food; their saliva is alkaline, and, like the grass-and-leaf eaters, it contains ptyalin for predigestion. Their intestines are extremely convoluted and are twelve times the length of their body, for the slow digestion of fruits and vegetables.
Human Beings
Human characteristics are in every way like the fruit eaters, very similar to the grass- eater, and very unlike the meat eaters. The human digestive system, tooth and jaw structure, and bodily functions are completely different from carnivorous animals. As in the case of the anthropoid ape, the human digestive system is twelve times the length of the body; our skin has millions of tiny pores to evaporate water and cool the body by sweating; we drink water by suction like all other vegetarian animals; our tooth and jaw structure is vegetarian; and our saliva is alkaline and contains ptyalin for predigestion of grains. Human beings clearly are not carnivores by physiology -- our anatomy and digestive system show that we must have evolved for millions of years living on fruits, nuts, grains, and vegetables.
Furthermore, it is obvious that our natural instincts are non-carnivorous. Most people have other people kill their meat for them and would be sickened if they had to do the killing themselves. Instead of eating raw meat as all flesh-eating animals do, humans boil, bake, or fry it and disguise it with all kinds of sauces and spices so that it bears no resemblance to its raw state. One scientist explains it this way: "A cat will salivate with hungry desire at the smell of a piece of raw flesh but not at all at the smell of fruit. If man could delight in pouncing upon a bird, tear its still-living limbs apart with his teeth, and suck the warm blood, one might conclude that nature provided him with meat-eating instinct. On the other hand, a bunch of luscious grapes makes his mouth water, and even in the absence of hunger he will eat fruit because it tastes so good."
Scientists and naturalists, including the great Charles Darwin who gave the theory of evolution, agree that early humans were fruit and vegetable eaters and that throughout history our anatomy has not changed. The great Swedish scientist von Linné states: "Man's structure, external and internal, compared with that of the other animals, shows that fruit and succulent vegetables constitute his natural food."
Lastly, across the Pacific in North Korea, after many many failed conversations, perhaps the power of music will be the thing that unites America and North Korea. Just this week, the NY Philharmonic traveled to North Korea and performed in front of their people. This article really shows how some things are just greater than all the political differences that we may have... and perhaps North Koreans aren't all just heartless, ruthless people as the media so often shows them to be...
