Here's information on that urban legend:

http://www.snopes.com/movies/actors/valentin.htm

The way I remember it, there were autopsy reports on finding abnormal
amounts of alluminum in the brains of Alzheimer's patients that made
some people afraid of using alluminum cookware. I first heard this in
the 1980s and didn't know the rumors went back to the 1920s until I
checked Snopes. Later reports debunked the original research, but that
didn't make as big an impact in the news.
