"Copper May Play Key Role in Alzheimer's Disease"

"New research finds that copper in amounts readily found in our drinking water, the foods we eat and the vitamin supplements we take likely plays a key role in initiating and fueling the abnormal protein build-up and brain inflammation that are hallmarks of Alzheimer's disease."

"While the mineral is important to healthy nerve conduction, hormone secretion and the growth of bones and connective tissue, a team of researchers from the University of Rochester Medical Center suggested that too much of it may be a bad thing, and they set about to explore copper's dark side.

What they found, said neuroscientist Rashid Deane, is "pretty scary": A steady diet of copper, even at entirely allowable levels, breaks down the barrier that keeps unwanted toxins from entering the brain, and that it fuels an increase in production of beta-amyloid but impedes the performance of proteins that clear the stuff from the brain."
