http://www.asylum.com/2008/09/15/a-vegertarian-diet-shrinks-the-brain According to a new study, vegetarians and vegans are six times more likely to suffer from brain shrinkage than meat eaters. The link was discovered after scientists at Oxford University ran memory tests, physical checks and brain scans on 107 people between the ages of 61and 87, and then retested them five years later. Researchers speculate the loss of brain mass in vegetarians and vegans is due to a deficiency of Vitamin B12, which is found in meat, fish and eggs. This type of brain atrophy is linked to Alzheimer's Disease and other cognitive failings. The decision to eat meat is often attacked by veggies, but it now seems as though these kinds of affronts may just be a product of small-mindedness. Regardless, we fully support continued naked protestation.
