Vegetarian Diet Shrinks Brain?

I've often wondered why vegetarianism frequently (though certainly not always), in the West at least, seems to correlate with a hearty embrace of the most nonsensical and unworkable political and social ideas. I wonder if this could be part of it.
Scientists have discovered that going veggie could be bad for your brain-with those on a meat-free diet six times more likely to suffer brain shrinkage.
Vegans and vegetarians are the most likely to be deficient because the best sources of the vitamin are meat, particularly liver, milk and fish. Vitamin B12 deficiency can also cause anaemia and inflammation of the nervous system. Yeast extracts are one of the few vegetarian foods which provide good levels of the vitamin...
When the volunteers were retested five years later the medics found those with the lowest levels of vitamin B12 were also the most likely to have brain shrinkage. It confirms earlier research showing a link between brain atrophy and low levels of B12.
Drinking also doesn't seem too helpful.
Interesting. Thank you, Tim. I think I'll be more active in watching my B-12 intake now. ;-) (I knew to watch it, but between this and seeing a show mentioning pernicious anemia, perhaps someone is hinting that I should look at my intake...)
Note that you do get B-12 from milk and eggs, which, thankfully I can digest. It's not a vegetarian-per-se diet but the vegan diet that lacks B-12. That diet is just plain stupid anyway.
(For those unfamiliar with my condition: Vegetarian by force, not by choice.)
You saw that episode "Mystery Diagnosis" yesterday also, eh? Too funny: I almost never watch TV, so it's a bit odd that we both caught it.
You're right: I should have more clearly focused on veganism.
People often refer to India as a sign that vegetarian diets can be safe -- but of course, they got their vitamins from milk and (don't mean to gross anyone else out, but) dung, which was often present in the diet due to, um, traditional sanitary conditions.
Funny coincidence that, since I usually ignore television also, but Michelle had that show on. (I didn't even know that was the show...)
Unfortunately, people referring to India don't seem to know much about it actually. It's not a very nice place.
[The World Bank's] ...report "Wasting Away - The Crisis of Malnutrition in India" blames poverty and low status of women for some of its most shocking statistics - half of all children under four are malnourished, it says, and 60% of women are anaemic
Most of that has to do with food prioritization within the family according to their report, but still not quite a good statistic.
