This theory has been advanced before, with the blame falling on the aluminum cans that beer and soft drinks are delivered in. Nothing conclusive could be demonstrated then, has the research gotten better, or is the aluminum coming from some other source?
Or is there simply a new search for research funding?
One major source of aluminum is antacids. My father took Maalox for 40 years or so and he’s got Parkinson’s now. There is no proof it’s related but I can clearly see how it could be.
