Aluminum in Drinking Water Connected to Dementia: “Exposure to aluminum in drinking water can increase your person’s risk of developing Alzheimer’s disease, but silica could reduce the risk. In a recent study, researchers followed elderly subjects for 15 years to learn whether the presence of aluminum in their drinking water would increase their chances of experiencing dementia, Alzheimer’s disease or cognitive decline.
Researchers found that consuming at least 0.1 milligram per day of aluminum was associated with greater cognitive decline. However, they also determined that consuming 10 milligrams per day of silica reduced the chances of dementia by 11 percent.
The investigators believe that further studies are needed to settle the debate over the link between aluminum in drinking water and neurological disorders.
