And can you tell me if the online sources are true or not about the vegetarian myth?

And the same teeth with pandas. Most of their life is filled with eating bamboo, but it's completely different with a human's usual fruit or veggies, and how about the difference between the human digestive system and the herbivore?

Not only is there no significant health difference between veggie diets and a well balanced omnivore diet, but vegetarians and vegans are usually more physically weak from not getting the proper type of protein.

No, it won't kill you, but it will reduce muscle mass and weaken bones. Do not listen to the propaganda. If meat was so bad for you we wouldn't have kept eating it for our entire existence.

Of all who posted, I want you to give me one biological indication that humans are designed to eat meat, and as for the history of eating meat and other animal based products, farms were not always available or supermarkets so humans had to eat whatever they could to survive.

And there was a post earlier on how people in the arctic, like eskimos, eat whale blubber and have no long term health effects. Most, if not all, have short life spans. Enough said.

For example, Colin Campbell, author of "The China Study" has been shown to have deliberately skewed and misrepresented his faulty data to suit his needs.

And the PCRM -which literally doesn't have HALF the number of accredited doctors or physicians on staff as you disingenuously assert- is nothing more than a propaganda-peddling front organization for the vicious animal rights terrorist cult calling themselves PETA.

You should be ashamed of yourselves, passing off propaganda and pseudoscience that may have a very adverse health effects for anyone gullible enough to believe this garbage.

Yup, because we're naturally omnivores, perfectly capable of safely digesting meat, contrary to the lies presented here by animal rights cultists.

There is no evidence in this article. There are a lot of references to studies, but no direct citations. Nice try.

"How can we not be meant to be vegan, when every other mammal on the planet gets weaned off milk?"

I don't see any mammals apart from humans that, in effect, are never really weaned, since they continue to drink cow's milk, cheese, etc.

Maybe have a bit of a think before posting next time, eh?

it isn't something that needs to be consumed daily. The problem with a lot of people is that they don't like hearing that veggies are good for you.

All your points make me laugh. Milk is for babies, not for adults! The studies are there so do your research! Studies since the 1900s have shown that meat is bad so get over it.

The US government has funded several "studies" to prove the correlation between meat and heart disease. So far they've not been able to make that link. Why? Because it's a big fat lie.

It would make your argument much more credible.

This follows that, in fact, scientists found B12 producing bacteria that were present in the soil and on plants. So, the argument that we're naturally meat eaters because of a vitamin that is actually found in the plant kingdom is weak and flawed.

Not only this, but our daily requirement is negligible amounts and we have a very efficient storing system of B12 in our liver, which gives rise to the fact our ancestors didn't retrieve their B12 from animals, but rather bacteria. Today's enormous pressure for the vegetable industry to yield large and perfect crops has forced farmers to extensively use pesticides, herbicides and harsh chemicals which have been found to kill these aforementioned bacteria, which explains why vegans require supplements. B12, one of many vitamins, cannot be the basis of your entire argument surely, because that seems almost void of all meaning.

Were these studies done on meat eaters who make nutritionally sound choices or meat eaters in general? I'll bet the latter, which means a man living on fish, chicken and veggies gets lumped in with a guy living off bacon and Mt. Dew.

To anon86302: Fossil evidence of modern man has been found in Africa dating back 200,000, not 60,000 years. And the the precess used to determine it's age, carbon dating, has nothing to do with DNA.

While flat teeth are associated with herbivores, this is not an infallible indication. Pandas, for instance, have the sharp teeth indicative of carnivores and yet live almost entirely on vegetation. Even if your oversimplification pertaining to the role of teeth as a dietary indicator was viable, would not a naturally omnivorous animal also have flat teeth (like in pigs)?

Modern vegans get B12 either by taking supplements, or by using products such as textured vegetable protein or nutritional yeast flakes that have B12 added to them.

It is highly unlikely that any native people ever had a wholly vegan diet, simply because of this necessary nutrient. Most primitive people ate mostly fruits, nuts and berries because that was what was available, but they did occasionally eat some sort of non-plant product. Perhaps they caught fish, or ate wild birds' eggs, but it's a biological fact they ate something besides plants once in a while.

My point is not to get caught up in the "humans are naturally vegan" thing because the evidence very loudly says otherwise. Tout the vegetarian/vegan lifestyle's health benefits all you want, but when people make the "not ever meat-eaters" argument, they are on shaky ground, indeed.

More to your point, humans are adaptive. It wasn't possible to have a vegetarian diet in all cases in the past. People ate what the surrounding land offered, and lived pretty short life spans for a myriad of reasons. They likely did not live long enough to suffer the long-term effects of a meat diet. They also ate untainted meat, not like the meat you eat today.

And I have no idea why you assume there were no vegetarian ancestors. Where edible plants, berries and fruits were plentiful, there likely were many peoples who did not hunt simply because it would not have been required. Our teeth are clearly the flat, grinding teeth of vegetarians, not the pointed teeth of a meat eater. It's no surprise our bodies do better without meat.

Seeing such a skewed presentation of things on this site is rather disconcerting.
