It has been shown that dietary aluminum increases the risk of Alzheimer disease. Yet our cities are allowed to put aluminum in our drinking water for no other reason than to make it look clean. Studies show that thousands of cases of Alzheimer's could have been prevented if there had been less than 100 micrograms per liter of aluminum in the drinking water they consumed yet the World Health Organization recommends a limit of up to 200 micrograms per liter. Do you know how much aluminum your city puts in your water? Is there a filter or water purifier that filters out aluminum?
