Many people ask, "If we weren't supposed to eat meat than why do we?". It is because we are conditioned to eat meat. Also, the ADA (American Dietetic Association) tells us that "most of mankind for most of human history has lived on a vegetarian or Lacto-ovo vegetarian diet."
A popular statement that meat eaters say is; "In the wild, animals kill other animals for food. It's a part of nature." First of all, we are not in the wild. Secondly, we can easily live without eating meat and killing. We all would be healthier this way.
We weren't meant to eat meat. Meat putrefies within 4 hours after consumption and the remnants cling to the walls of the intestines for 14-21 days. If a person is suffering from constipation the rotting meat can stay in the intestines for months or years.
Meat can stay in the warmth of the intestine for at least four to five days until it is digested. It does nothing but wait for passage. Often, it usually stays there for much longer. Medical doctors have found traces of undigested meat remaining in the colon for up to several months.
Furthermore, the saliva in humans is more alkaline, whereas in the case of flesh-eating or preying animals, it is clearly acidic. The alkaline saliva does not act properly on meat. Our Hydrochloric Acid isn’t strong enough to fully digest meat.
Tigers or lions that eat meat have acid-based digestive systems. Also, their intestines measures about five feet long, not twisted and turned, layer over layer, compacted into a small area like the human intestine [which is twenty feet long].
The final point on how we as humans were not meant to eat meat is this; all omnivorous and carnivorous animals eat their meat raw. When a lion kills an herbivore for food, it tears right into the stomach area to eat the organs that are filled with blood (nutrients). While eating the stomach, liver, intestine, etc., the lion laps the blood in the process of eating the dead animal's flesh. Even bears that are omnivores eat salmon raw. However, eating raw bloody meat disgust us as humans. This is why meat is cooked and seasoned to buffer the taste of the flesh.
If a deer is burned in a forest fire a carnivorous animal will NOT eat its flesh. Even circus lions have to be fed raw meat so that they will not starve to death. If humans were truly meant to eat meat then they would eat meat raw and bloody. The thought of eating such meat makes one’s stomach turn.
If man is a true carnivore or omnivore he would eat animal flesh raw and bloody. Cooking the meat and seasoning it with salt, ketchup, mayo, mustard or tabasco sauce disguise the awful taste of flesh. This is the only way humans would eat meat because they refuse to eat it raw and bloody like real carnivores.
