Debunking the Myth of Aluminum and Alzheimer's
When inspected under electron microscope, the neurofibrillary tangles associated with aluminum appear to be different from those associated with Alzheimer's disease. Scientists have not been able to replicate the findings of increased aluminum in the brains of so-called AD victims. Despite the concern that the initial findings have caused, the whole aluminum theory seems to have been a red herring. As for the population studies that suggested greater risk with increased aluminum exposure, many other explanations could account for the statistical connections.
Aluminum is a very common metal in human ecosystems. It is present in pots and pans, antacids, and even deodorants. Avoiding exposure would be practically impossible.
The weight of evidence suggests that we need to take no actions with regard to avoiding exposure to aluminum despite the early observations that have created considerable consternation and worry that persists today.
