Conclusions from 28 medical studies linking fluoride to lower IQ in children
To date, there are at least 53 known
international scientific studies concluding that fluoride consumption is harmful to
the development of intelligence in children, it impairs their learning and memory
capacity. Children are commonly exposed to fluoride from municipal water supplies,
dental treatments, environmental pollution, and in-utero.
Municipal water fluoridation is a state-mandated
pharmacological intervention that ostensibly aims to fight dental fluorosis, but
this claim is highly contested, and a growing body of research indicates that water
fluoridation is linked to lower IQ in children. Medication without consent is a
human rights violation.
In 2017, former EPA senior scientist, William
Hirzy, PhD noted:
“The significance of this peer reviewed
risk analysis is that it indicates there may be no actual safe level of exposure to
fluoride. Groups of children with lower exposures to fluoride were compared with
groups having higher exposures. Those with higher exposures performed more poorly on
IQ tests than those with lower exposures.” William Hirzy, PhD
Here is a sampling of some of the shocking
conclusions from these studies, as documented by The Fluoride Action Network, where a full breakdown on these
studies, as well as comments about study methodologies and locations, may be
found.
“Chronic exposure to high levels of
fluoride in water was observed to be associated with lower intelligence
quotient.” IQ Study #41: Nagarajappa
(2013)
“School children residing in area with
higher than normal water fluoride level demonstrated more impaired development of
intelligence when compared to school children residing in areas with normal and low
water fluoride levels.” IQ Study #47: Sebastian
(2015)
“[C]hildren residing in areas with
higher than normal water fluoride level demonstrated more impaired development of
intelligence and moderate [dental fluorosis]. Millions of children including adults
around the world are affected by higher level of fluoride concentration through
their drinking water and are therefore potentially at risk. It is concluded that for
the benefit of the future generation, urgent attention should be paid on this
substantial public health problem.” IQ Study #50: Das (2016)
“[S]tudents of the study area have less
IQ than students of non-contaminated area, demonstrating that consumption of F also
has a major role with the intellectual development of children.” IQ Study
#49: Mondal (2016)
“The data from this research may
support the hypothesis that excess fluoride in drinking water has toxic effects on
the nervous system.” IQ Study #48: Khan (2015)
“Fluoride in the drinking water was
significantly related with the IQ of children. Along with fluoride, mother’s
diet during pregnancy was also found to be significantly related with IQ of
children.” IQ Study #46: Kundu
(2015)
“Results of our field study raise a
concern about the safety of elevated systemic exposure to fluoride from high
concentrations in the drinking water. While topical fluoride treatment confers
benefits of reducing caries incidence, the systemic exposure should not be so high
as to impair children’s neurodevelopment especially during the highly
vulnerable windows of brain development in utero and during infancy and childhood
and may result in permanent brain injury.” IQ Study #45: Choi (2015)
“Exposures to fluorine and arsenic are
deleterious to the development of intelligence and the development of growth in
children” IQ Study #43: Bai (2014)
“We observed reduced AChE activity in
[the high fluoride area] which may be directly correlate[d] with the reduced
intelligence score of the subjects.” IQ Study #40: Singh
(2013)
“The study found that children residing
in a region with a high drinking water F level had lower IQs compared to children
living in a low drinking water F region (p<0.001). The differences could not be
attributed to confounding educational, economic, social, cultural, and general
demographic factors.” Karimzade
(2014)
“This study indicates that exposure to
fluoride is associated with reduced intelligence in children.” IQ Study
#36: Saxena (2012)
“In conclusion, our study suggested
that low levels of fluoride exposure in drinking water had negative effects on
children’s intelligence and dental health and confirmed the dose-response
relationships between urine fluoride and IQ scores as well as dental
fluorosis.” IQ Study #35: Ding (2011)
“Based on the findings, chronic
exposure to high levels of fluoride can be one of the factors that influence
intellectual development.” IQ Study #34: Poureslami
(2011)
“Previous studies had indicated toward
decreased Intelligence in children exposed to high levels of fluoride and our study
also confirmed such an effect.” IQ Study #32: Shivaprakash
(2011)
“Findings of this study suggest that
overall IQ levels in children’s exposed to high fluoride level were
significantly lower than the low fluoride areas.” IQ Study #31: Sudhir
(2009)
“High exposure to fluoride most
definitely has an adverse effect on the development of intelligence in children, in
particular on the capability of abstract inference.” IQ Study #30: Li (2009)
“This study indicates that exposure to
fluoride in drinking water is associated with neurotoxic effects in
children.” IQ Study #28: Wang (2007)
“In agreement with other studies
elsewhere, these findings indicate that children drinking high F water are at risk
for impaired development of intelligence.” IQ Study #27: Trivedi (2007)
“Exposure to high levels of fluoride is
likely to cause a certain level of harm to a child’s level of
intelligence.” IQ Study #26: Fan (2007)
“Based on the findings of this study,
exposure of children to high levels of fluoride may carry the risk of impaired
development of intelligence.” IQ Study #25: Seraj
(2006)
“High fluoride burden has a definite
effect on the intellectual and physical development of children.” IQ
Study #24: Wang (2005)
“The findings of this study thus
replicate those of earlier studies and suggest that a real relationship exists
between fluoride exposure and intelligence.” IQ Study #18: Lu (2000)
“These results show that water
improvement and defluoridation can improve the mental and physical development of
children in a fluorosis area.ˮ IQ Study #16: Yao (1997)
“The results of the intelligence tests
show that a high level of fluoride influences children’s IQ, which is
consistent with some previous data. It is worth mentioning that the higher the
degree of dental fluorosis, the more negative the impact on the children’s
intelligence level. This is an issue which merits utmost attention.” IQ
Study #15: Yao (1996)
“The results show that a high fluoride
intake has a clear influence on the IQ of preschool children, manifesting itself
primarily as damage to performance intelligence.” IQ Study #13: Wang (1996)
“A high fluoride intake was associated
with a lower intelligence.” IQ Study #11: Li (1995)
“The results show that the level of
intelligence of primary and secondary students from the high fluoride area and that
of primary and secondary students from the non-high fluoride area had very
significant differences, proving that high fluoride has adverse effects on the
mental development of students. The higher the water fluoride is, the lower the
level of IQ.” IQ Study #7: An (1992)
“The results of this study indicate
that there is significant difference between the intellectual ability of the
7–14 year old children from the [fluorosis] endemic area and those of the
control, and moreover that the average IQ of the children from the endemic area is
clearly lower.” IQ Study #4: Chen (1991)
