Federal report finding fluoride lowers IQ of children reviewed by National Academy of Sciences
Federal report finding fluoride lowers IQ of children reviewed by National Academy of Sciences
The National Academy of Sciences (NAS)
just released an assessment of
a draft report
on fluoride neurotoxicity produced by the National Toxicology Program (NTP). The
NAS suggested improvements to strengthen the report and heavily
criticized NTP for ignoring evidence from animal studies and for
inadequately addressing the human evidence at fluoride levels common in
the USA, reports the Fluoride
Action Network (FAN).
Paul Connett,
PhD, Director of FAN, an environmental group, welcomed the NAS report
and said, "If
the recommendations are adopted, they will make the final
report 'iron-clad' against criticisms. The
NAS suggestions should strengthen the draft report's conclusion that
fluoride is a presumed neurotoxin in children, which is based on 149
human studies. This finding brings into question the long-standing
assurances from public health officials that water
fluoridation is safe."
Connett went
on to say, "The NAS review has been misinterpreted by fluoridation
defenders. The NAS did not independently review the scientific evidence
but instead limited itself to comments on whether
the NTP clearly and thoroughly explained their methods. The
NAS emphasized its finding '… does not mean that the NTP's conclusion is
incorrect.'"
"Many NAS
suggestions are minor and should have little effect on the conclusion of
'presumed' neurotoxic in children. However, the inclusion of the
hundreds of identified animal studies, as recommended
by NAS, can only increase confidence in the conclusion."
"The other
main NAS criticism was that NTP inadequately addressed the question most
people are interested in: Does fluoridated water pose a neurotoxic
risk? Criticizing NTP's vague discussions about
uncertainty over this question, the NAS recommends NTP do a proper
dose-response analysis to address this issue head-on. FAN believes such
an analysis will confirm there is sufficient evidence linking water
fluoridation to lowered IQ and other neurotoxic effects."
Connett
further stated, "Multiple strong scientific studies, at exposures
relevant to fluoridation, have been published after the NTP's
review. They link fluoridation in Canada to greatly lowered IQ
in formula-fed infants (Till
2020) and 300% higher rates of ADHD (Ridell
2019); fluoridation in USA with sleep disturbances in adolescents (Malin
2020); and fluoride with lower IQ by thyroid disruption (Wang
2020)."
