The World Health Organization (WHO) estimates that there are 18 million people with Alzheimer's. Over 4 1/2 million Americans have the disease. We account for 25% of all Alzheimer's cases, even though we represent only 4.6% of the world's population. Europe is experiencing half our rate of disease. For Americans over 85 years of age, 50% are thought to have Alzheimer’s

In 1998 Julie Varner and two colleagues published research on the effects of aluminum-fluoride and sodium-fluoride on the nervous system of rats. They concluded, "Chronic administration of aluminum-fluoride and sodium-fluoride in the drinking water of rats resulted in distinct morphological alterations of the brain, including the effects on neurons and cerebrovasculature." In layman's terms, it looked like fluoride and aluminum could cause Alzheimer's.

That was not a definitive study, but they may have been onto something. Aluminum is in our drinking water, foods, and many consumer products. Adding fluoride to drinking water in the U.S. started in the 1950's. America's drinking water is now over 60% fluoridated. Fluoride appears in many processed foods and beverages made with fluoridated water. Keep in mind, Europe has half our rate of Alzheimer’s. They don't fluoridate their water supplies, but they do use fluoride supplements and dental products.
