Can cooking with aluminum pots and pans give you Alzheimer's?
No one knows the causes of Alzheimer's, and scientific studies associating aluminum with the disease are conflicting. The Alzheimer's Association website states, "The majority of mainstream scientists"—as well as the World Health Organization, the National Institutes of Health and the Environmental Protection Agency—"now believe that if aluminum plays any role at all in Alzheimer's, that role is small." People would have to ingest an almost comically inhuman amount of aluminum from cookware to come close to the levels reported to be found in Alzheimer's patients' brains.

Bottom line: The risk doesn't pan out.
