Dear Editor, I was shocked to learn that City Council recently approved a new contract with Mosaic to supply four more years of fluoride to add to the city of Austin's drinking water. They must not be aware of the new study published in the March 2014 journal Lancet Neurology, in which medical authorities newly classified fluoride as a developmental neurotoxin. The authors point out that 27 studies of children exposed to fluoride in drinking water found an average lowering of IQ by seven points; twice that of the effects of secondhand smoke on children. The majority of these 27 studies had water fluoride levels which the U.S. Environmental Protection Agency currently allows in the U.S. – less than 4 milligrams per liter. This is not "junk science" or a conspiracy theory. Therefore, given the overwhelming evidence linking fluoride to developmental toxicity, why would the city continue to focus only on protecting children's teeth rather than their brains? The city claims fluoride is added to the water for the potential public health benefits, yet no other medication or supplement is added to our water supply for health benefits. Why not force citizens to take other supplements like folic acid, iron, or calcium? Naturally occurring fluoride is already present in our water. In addition, it is present in many of the foods we eat. Furthermore, topical administration via toothpaste and dental treatments provide more than adequate amounts of additional fluoride in the proper way. Ingestion of the chemical is both harmful and unnecessary. Adding fluoride to the Austin water supply should be stopped. We should be free to make our own health choices about what supplements we ingest. And if the city thinks there is public support for water fluoridation, why not let the citizens of Austin decide whether or not we want this neurotoxin in our water? And by the way, I am a lifelong Texan, graduate of UT-Austin, a fortysomething mother of two, and I voted for most, if not all, of the current council members.
