In one of the most unhelpful reports in memory (and about memory), the BBC cites research suggesting that too much copper in our diets may contribute to Alzheimer’s disease, and it cites other research suggesting that the metal did just the opposite. First the bad news: researchers at the University of Rochester found that mice with more copper in their brains had a greater buildup of a protein called beta amyloid, which is believed to cause Alzheimer’s disease. The BBC also cites research conducted at Keele University, which seems to indicate that lower brain copper correlated with higher deposition of beta amyloid in brain tissue. The best thing to do with these conflicting reports? Forget one of them. Read more from the BBC.
