> you too, are likely to be running a vitamin B12 deficiency
Citation please? I've looked into this subject pretty intensely over the last decade or so and know of no controlled studies (or even poorly done observational studies) that demonstrate this in the least. The only place I've ever even seen this claim is on vegan advocacy forums as unsubstantiated claims or in studies of nutrition absorption problems as a general factor in the elderly. The amount of animal meat needed for full dietary B12 is actually shockingly small. A few grams a week. And it's water soluble so you just piss out any that's not used.
On the contrary I've read several studies that show that in the study populations, up to 92% of the vegans in the population were B12 deficient.
In another a little over 50% of vegans were deficient, while less than 10% of vegetarians and a single omnivore were B12 deficient.
I know of no studies where the studied, randomly sampled, vegan population was not majority B12 deficient.
In other studies that look for it, elevated methylmalonic acid (associated with B12 deficiency) was found in the vast majority (over 80%) of vegans while only 5% of ominivores and 68% of vegetarians. In the same study almost 70% of vegans were diagnosed with Hyperhomocysteinemia (caused by sustained deficiencies in B-vitamin groups or chronic alcoholism) while less than 20% of the omnivores were.
The most effective and reliable treatment for Hyperhomocysteinemia is a regular omnivorous diet of meat and eggs with a cure rate of nearly 100%.
"Vitamin B-12 deficiency and depletion are common in wealthier countries, particularly among the elderly, and are most prevalent in poorer populations around the world. This prevalence was underestimated in the past for several reasons, including the erroneous belief that deficiency is unlikely except in strict vegetarians or patients with pernicious anemia, and that it usually takes ≈20 y for stores of the vitamin to become depleted."
"Vitamin B12 deficiency is a common but under-recognized, yet easily treatable disorder in older adults. Although several causes exist, food-cobalamin malabsorption is now believed to be the most common etiology."
"The only place I've ever even seen this claim is on vegan advocacy forums as unsubstantiated claims or in studies of nutrition absorption problems as a general factor in the elderly."
I'm looking for non-elderly studies, who, because of general age-related issues suffer from all-around nutritional deficiencies. In other words, we already know old people are sick in a variety of ways, I'm challenging you to support your claim, directed to non-vegans that

I want to say it's absurdly untrue and laughable on its face, but I'm willing to eat my words if you can produce a couple independent studies that demonstrate your claim without citing some unattributed nonsense from veganforum.com or other rubbish filled site.
