Gov. Study Confirms Fluoride Harms Fetal Brain; Lowers IQ
The first ever US government funded study of fluoride and IQ reveals that pregnant women exposed to fluoride lowers the IQ of their offspring.
The study, published in Environmental Health Perspectives and funded by the National Institute of Environmental Health Sciences, confirms that mothers who drink water contaminated with fluoride will see a loss of 6 IQ points in their children.
The study was conducted in Mexico City using a long-running cohort of women-infant pairs that have been studied extensively for effects of environmental neurotoxins such as lead and mercury. It found an average loss of 5 to 6 IQ points among children of mothers with urine fluoride levels of 1.5 mg/L compared to those with 0.5 mg/L. For an entire population, such a loss would be expected to halve the number of geniuses in society and double the number of mentally handicapped. For IQ measured at 4 years of age, there was no apparent fluoride exposure threshold below which the effect leveled out.
