> They also claim that aluminum causes alzheimers disease.
Er, no, they didn't say that. What they said is that it has been linked to
Alzheimer's, which is true. A majority of Alzheimer's patients show
unusually high amounts of aluminum in their (damaged) brain tissue. As far
as I know, no one has yet been able to show conclusively whether the
aluminum caused the Alzheimer's, or the Alzheimer's caused the aluminum, or
something else caused both of them. Correlation does not imply causation.
Only took us 2000 years to figure out that lead is poison; and aluminum has
only been in common use for less than 100 years. Might be we don't know
everything there is to know about it.
