High caloric intake enabled brains of our prehuman ancestors to grow dramatically
Vegetarian, vegan and raw diets can be healthy likely far healthier than the typical American diet. But to continue to call these diets "natural" for humans, in terms of evolution, is a bit of a stretch, according to two recent, independent studies.
Eating meat and cooking food made us human, the studies suggest, enabling the brains of our prehuman ancestors to grow dramatically over a period of a few million years. Although this isn't the first such assertion from archaeologists and evolutionary biologists, the new studies demonstrate, respectively, that it would have been biologically implausible for humans to evolve such a large brain on a raw, vegan diet and that meat-eating was a crucial element of human evolution at least 1 million years before the dawn of humankind.
Shhh, don't tell the gorillas
At the core of this research is the understanding that the modern human brain consumes 20 percent of the body's energy at rest, twice that of other primates. Meat and cooked foods were needed to provide the necessary calorie boost to feed a growing brain.
One study, published last month in the journal Proceedings of the National Academy of Sciences, examined the brain sizes of several primates. For the most part, larger bodies have larger brains across species. Yet humans have exceptionally large, neuron-rich brains for our body size, while gorillas three times more massive than humans have smaller brains and three times fewer neurons. Why?
The answer, it seems, is the gorillas' raw, vegan diet (devoid of animal protein), which requires hours upon hours of eating only plants to provide enough calories to support their mass.

And rabbit itself....tastes like chicken.
I wear elk moccasins...inside and out...can't wear the damn things out. Love'm.
I also have a full length seal coat that I got at a garage sale for $4.00. The skins say Africa. It's over 100 years old. Velvet is like brillo compared to sealskin. Awesome.
This is how I believe. "God didn't make anything on earth just for the mere sake of beauty. He left that to the sun and moon and stars. And we stand in awe of such wonders."
In the early 17th century, the Sikhs switched their policy from pacifism to armed resistance against Muslim oppression.
To further this switch, although they had previously been vegetarians, they were instructed by their Guru to eat meat so they would grow strong.
Almost all mammalian herbivores have gut specializations and flora that allow them to kinda retain and “ferment” their foods.
No such items in humans.
Actually, human “pass through” time is more like carnivores, who digest and pass through their foods quickly.
It also provided leisure for music, dance and various intoxicants leading to self-awareness.
This certainly explains why vegans are always narrow minded small brain people.
no....vegetarians maybe...but vegans eat NO products that originate from any animals. they are like sheep.
That is what is so good about meat, you don’t need that much and it replaces so many bananas or apples when it comes to protiens and amino acids.
You’d have to eat 23 bananas to get the protien from 3 oz of lean ground beef. Bananas are good but for totally different reasons.
It is called balance and eating to get the nutrients your body needs.

As an extreme example, the Eskimos. Not that much vegetation up on the Arctic Circle, so their traditional diet is predominantly meat, fish, birds and bird eggs.
Add to that the populations of northern Siberia and the Laplanders whose diet and life support systems consist almost entirely of one single animal:
Rudolph!
Some limited fish and seal, but not much.
The reindeer are the only large animal that can eke out an existence from the lichens and very sparse vegetation.
They eat the plants.
The people eat the reindeer.
The cow ate the grass.
I ate the steak.
There is symmetry.
And alcohol focused that brainpower into civilization, and provided sterilized water to drink.
Fermentation required a basic scientific and manufacturing process. Alcohol killed off all the nasties living in most water.
Here’s to steak and beer!

And let's not forget the Plains Indians before white settlers came. There's not much on the plains but grass and buffalo. The buffalo ate the grass and the Indians ate the buffalo.
Environmentally-correct education bemoans the "senseless slaughter" of the buffalo herds when the white man came, but there was a very rational purpose behind it. The Indians were nomadic and very hard for the US Cavalry to track down, and could put up a fight when they WERE found, as General Custer discovered. But the Indians could not survive without buffalo, so if you want to get rid of the Indians, the simplest method was to get rid of the buffalo.
Human beings were designed by God (or by "Mother Nature",for all you atheists) to be omnivores.Anyone needing proof should ask any dentist.
I certainly don’t advocate anyone start eating large amounts of fatty meat every day, but the food nazis can drive a person over the edge. I’ve heard a few claim humans didn’t start eating meat until about ten thousand years ago because of some huge food crisis. I asked one young veggietarian who told me that story why humans have incisors and not all molars. He had no answer.
Not too long ago, a scientist studying nutrition was puzzled, because he wanted to know the nutritional difference between raw and cooked food, and couldn’t find any research about it.
Then he discovered that when calories of food were determined with an elaborate device called a calorimeter, which determines calories by incinerating food, no distinction was made between raw and cooked food.
He knew that digestion can only get a fraction of the nutrition from raw food compared to cooked food, so there should be a huge difference in “available calories”.
To check this out, he studied people who were on a raw food only diet, and discovered that even if they ate considerably more raw food calories, almost every one had at least some form of malnutrition.
The implications of this are that the calorie tables put on food are wildly inaccurate, and need significant adjustment. Proteins, fats, carbohydrates and their subset sugars, as well as vitamins and minerals, are all very different from what they are alleged to be.
However, it is not easy to tell how much nutrition is obtained from food, and how high up in the digestive tract. But until this is done, nutritional labels on food are wrong.

I know a woman who has never eaten meat. She is a health basketcase. Thin as a rail, constantly sick, Tries to live a “naural” life. Needs to smoke “medical marijuana” to ease her pains. Seventh Day Adventist. Nuff said.
