Association between maternal fluoride exposure during pregnancy and IQ scores in offspring in Canada
Published: 2019

Lower IQ in children is strongly associated with higher levels of maternal fluoride exposure during pregnancy.


Green R, Lanphear B, Hornung R, et al. JAMA Pediatrics. 2019;173(10):940-948.


In this Canadian study, maternal exposure to higher levels of fluoride during pregnancy was strongly associated with lower IQ in children. In addition, the study found that women living in areas with fluoridated tap water had significantly higher average concentrations of fluoride in their urine compared to women without fluoridated tap water. Fluoridated cities in Canada use the same fluoride concentration (0.7 milligrams per liter) as the U.S. has used since 2015—a concentration recommended by the CDC as “optimal.” The authors raise concerns about the safety of maternal exposure to “optimally fluoridated water” and note that, at the population level, their results translate to “millions of IQ levels lost.”

Immunoexcitotoxicity as the central mechanism of etiopathology and treatment of autism spectrum disorders: a possible role of fluoride and aluminum
Published: 2018

Fluoride and aluminum, alone or in combination, can produce the condition of “immunoexcitotoxicity” that leads to the pathological changes seen in autism.

Children experience sequential immune stimulation from a growing number of neurotoxic metals and chemicals, vaccines and persistent viral infections. This excessive immune activation is the “initiating and sustaining event” in autism spectrum disorder (ASD), triggering inflammation and a cascade of excitotoxicity (damaged nerve cells). The fluoride added to drinking water and the aluminum in vaccines—singly or synergistically as aluminofluoride—can be potent factors in producing the condition of “immunoexcitotoxicity” that leads to the pathological changes seen in ASD.
