(Natural News) The United States started adding fluoride to its drinking water soon after the end of the Second World War, and for over 70 years, the Centers for Disease Control and Prevention (CDC) has confidently asserted that this practice is necessary to prevent tooth decay. Interestingly, the U.S. is one of very few countries that still maintains that adding fluoride in this way prevents tooth decay.
The CDC maintains that several studies have demonstrated that the fluoride which naturally occurs in groundwater is essentially the same as the sodium fluoride that is added to our drinking water. The CDC’s website claims: “The metabolism of fluoride does not differ depending on the chemical compound used or whether the fluoride is present naturally or added to the water supply.” (RELATED: What else is the CDC getting up to?

Nonetheless, in 2012, the Department of Health and Human Services (HHS) amended its Public Health Service recommendations to mandate that fluoride levels not exceed 0.7 milligrams per liter, rather than the 0.7 to 1.2 milligrams per liter that had been recommended for the previous 50 years. The reasons supplied for the change included an increase in instances of dental fluorosis – a yellow or brown staining of the teeth caused by fluoride – as well as the fact that Americans are being bombarded with fluoride from several different sources, which was not the case in the past.
The truth is, though, that fluoride should not be added to our water supply at all.
A new meta-analysis conducted by researchers from New Zealand, and led by William Hirzy, Ph.D., a former senior EPA scientist who assessed risk for the agency, has found that the fluoridation of water is directly linked to a reduction in the IQ of exposed children. The study was entitled Developmental neurotoxicity of fluoride: A quantitative risk analysis towards establishing a safe daily dose of fluoride for children. The study compared the fluoride exposure of groups of children with low IQs to those whose IQs are higher and found that the higher the exposure to fluoride, the lower the IQ.
