The Oil Drum

wild caught animals wont go far between your population and if their not wild then they will be high fat as outlined in your first link.

Consequently, the human genome is most ideally adapted to those foods which were available to pre-agricultural man, namely lean muscle meats, limited fatty organ meats, and wild fruits and vegetables--but, significantly, not grains, legumes, dairy products, or the very high-fat carcasses of modern domesticated animals

meat and dairy products have been consitently linked to heart attack and cancer (also partly due to steroids, hormones and I suspect antibiotics that industrialised animals are fed) as outlined in your second link

Most of us today follow a diet containing a large amount of food which is not readily available in nature, and that must be highly processed to become edible. Our bodies were not made to handle such foods, and thus we suffer by dying of heart attacks, strokes, cancer, and complications from diabetes and osteoporosis.

reads very much like the atkins diet and he is trying to sell his book.

however i agree cereals and legumes should not be the basis of a diet, you would definetly get malnutrition.

I advocate a BALANCED vegan diet for optimum health and using less resources

nuts, seeds, berries, fruits, vegetables and some legumes, root vegatables and rice if you can get it

 a potato based diet is not good, but that is not to say potatos are bad for you.

as an aside britains oldest man was vegan lived till 111, cycled to work till he was 100 and retired at 104.

if you would like to know more about the free organic food that is available to you then go to
www.pfaf.org
they have a database of 7000 plants that are edible
happy foraging.

Ha, that beyondveg website is a joke, no scientific credibility.  If you seriously aren't aware of the thousands of scientific studies implicating animal products as the cause of the epidemic rates of "western" diseases, then you have no business commenting on the subject.  People love hearing good news about their bad habits, and that is what sites like beyondveg are all about.  It is exactly the kind of site that would call peak oilers crazy, and promote garbage like the abiotic oil theory.  Never heard of Dean Ornish, MD?  John McDougall, MD., PCRM.org?  These folks present their arguments based on scientific studies, not on feel-good assurances that the status quo is always right.  

And then bashing grains?  You sound like a raw fooder, lol!
If grain-based diets caused chronic disease then the incidence of western ilnesses like heart disease/cancer should be HUGE in the poor populations of the world that base their diets on grains. Instead, these diseases are nearly unheard of in these populations, which make up a major part of world population - clearly a glaring contradiction.

The book noted below is yet another elucidation of the unhealthiness of meat.  Even tiny amounts (by western standards) showed negative consequences.  5000 people in the US drop dead every day from artery diseases clogged and ruptured by what, rice and vegetables?  The head of The Framingham Heart Study, the grand prix of heart studies,
says they have never seen a case of heart disease from a person with a cholesterol lower than 150.  Guess what level cholesterol drops to when you stop eating meat and dairy?  under 150.

The China Study : The Most Comprehensive Study of Nutrition Ever Conducted and the Startling Implications for Diet, Weight Loss and Long-Term Health -- by T. Colin Campbell,

It's important to keep an open mind, but not so open your brain falls out.  (Carl Sagan?)  In my unpopular opinion, if you believe meat is healthy then your brain is flopping around on the ground, waiting to be picked up.

Off Topic

In most "traditional" cultures meat was considered a flavoring.

Best to limit all highly refined substances in one's diet, be they pastas or pepperonis.
