What's on tap for Alzheimer's prevention?

Ahhh ... now this is a study I would have paid for myself. Research out of the University of Alcala in Madrid, Spain found that drinking beer may protect against the harmful effects of aluminum on the brain.

In a report published in the January, 2008 issue of Food and Chemical Toxicology, Spanish researchers posited that aluminum is neurotoxic, and overexposure to this metal has been implicated for its suspected connection with Alzheimer's disease. Beer, on the other hand, contains silicon, a substance that reduces the buildup up aluminum in the digestive system and the brain.

The study found that consuming silicon in moderately high levels – which can be obtained from drinking about two beers per day - limited aluminum's debilitating effect on the brain.
