Based on current research, getting rid of aluminum cans, pots, and pans will not protect you from Alzheimer's disease. Aluminum is one of 90 naturally occurring chemical elements. It is the third most common element found in the earth's crust, after oxygen and silicon. The focus of ongoing research is to clarify how aluminum affects the body and whether it is a factor in Alzheimer's disease.
The exact role (if any) of aluminum in Alzheimer's disease is still being researched and debated. However, most researchers believe that not enough evidence exists to consider aluminum a risk factor for Alzheimer's or a cause of dementia.
