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.

Comments

Michael - if you're listening- you may want to consider sublingual B12 in particular. It routes around absorption issues. Also, creatine apparently may be beneficial, at least according to one recent study.


Also, interesting evidence that small amounts of creatine supplementation, which appears to be part of the process by which the body creates ATP (used for energy) also helps with memory in vegetarians.

source

subjects consumed either a placebo or 20 g of creatine supplement for 5 d. ... in vegetarians rather than in those who consume meat, creatine supplementation resulted in better memory. Irrespective of dietary style, the supplementation of creatine decreased the variability in the responses to a choice reaction-time task.
