Practically overnight, fluoride joined the likes of lead, arsenic, methylmercury, toluene and other chemicals known to damage brain tissue, reports the Fluoride Action Network (FAN).
In the March 2014 journal Lancet Neurology, the highly prevalent chemical was reclassified as a developmental neurotoxin by medical authorities.
The authors, Dr. Philippe Grandjean of the Harvard School of Public Health and Dr. Philip Landrigan of the Icahn School of Medicine write, “A meta-analysis of 27 cross-sectional studies of children exposed to fluoride in drinking water, mainly from China, suggests an average IQ decrement of about seven points in children exposed to raised fluoride concentrations.”
The majority of these 27 studies had water fluoride levels of less than four milligrams per liter, which falls under the allowable level set by the U.S. Environmental Protection Agency.
Developmental neurotoxins, which are capable of causing widespread brain disorders such as autism, attention deficit hyperactivity disorder, learning disabilities, often cause untreatable and permanent damage.
Grandjean and Landrigan write, “Our very great concern is that children worldwide are being exposed to unrecognized toxic chemicals that are silently eroding intelligence, disrupting behaviors, truncating future achievements and damaging societies, perhaps most seriously in developing countries.”
