Any Vegetarians/Vegans here?

[James2014]

There is ample evidence that the skeletons and skulls from people who live ages ago show no sign of omnivorousess so where is your evidence that they were omnivorous?

Unlike ruminants, eg cows, we do not have the specialized stomach compartments containing the bacteria required to digest cellulose. These bacteria in the cow also create b12, which means they do not require it in the diet. Now, we do have bacteria in our guts, but these live in the large intestine, which is after the small intestine which is where B12 is absorbed from.

We therefore require dietary B12, and the only reliable source of this is either meat, animal products or extracted from bacteria and put into supplements/fortified food. Now the last one wouldn't be available to pre modern people, and while it may be theoretically possible to obtain b12 from vegetables contaminated with b12 producing bacteria, I have never seen any evidence to suggest that this is sufficient.

Anyhow, here is a good summary that we are adapted to eat an omniverous diet from a rather less unbiased source http://www.vrg.org/nutshell/omni.htm

All this stuff about whether ancient civilizations surviving on a vegan/ vegetarian diet or not is completely irrelevant. No ancient society has ever survived while being completely reliant on industrial agriculture either but it doesn't mean that it is wrong. Indeed without modern agriculture and mechanisation etc we would not be able to feed ourselves. Its just ridiculous, do you think that thousands of years ago people debated whether to move away from being a hunter gatherer to start growing crops because no one had done it before? The fact is veganism is better for the environment, better for health and better for the animals.
