The old myth was that aluminum foil and cookware is linked to Alzheimer's Disease. It has been around since the 1980s
This myth has its roots in research from the 1960s and 1970s that showed elevated levels of aluminum in the brains of Alzheimer's patients. For years people were warned off of aluminum pots and pans, and even aluminum foil to store food.
Since those studies a great deal of research has been done into what possible connections aluminum may have with Alzheimer's Disease, and failed to show any substantive link or connection between aluminum and risk for Alzheimer's Disease.
Most experts now believe any aluminum absorbed by the body is processed by the kidneys, urinated out, and it does not pose a threat for Alzheimer's Disease.
