National Party Not Current On Fluoride Science
The National Party is relying on outdated and discredited science in its continued support of adding a hazardous waste (“fluoride”) to the public water supply. The most up-to-date scientific review has been completed by the US National Toxicology Program (NTP), finding that higher fluoride exposure is consistently associated with lower IQ in children (see page 13 of the Monograph).
The
NTP is in the final stages of publishing its findings from
this 6-year review into fluoride’s neurotoxicity. The top
science organisation in the United States of America the
National Academies of Science, Engineering and Medicine
(NASEM) has peer reviewed the NTP review twice.
On
the 16th of May 2023 the NTP Board of Scientific Counselors
(BSC) unanimously voted to release the final version within
the next few weeks/months. The latest draft review has been
released including the peer reviewer’s comments and the
NTP response to those comments.
The latest draft
review was made public in May and has not been considered by
the Ministry of Health (by its own admission) or the Office
of Prime Minister’s Chief Science Advisor.
The
NTP review was issued in two parts: a monograph and a
meta-analysis. The review concluded that prenatal and early
life exposures can reduce IQ and that the meta-analysis
could not detect a safe level of exposure. The meta-analysis
reported that 52 of 55 human IQ studies found lower IQ with
high and low fluoride exposures - 95% consistency. The
average reduction was 7 IQ points. Leaded petrol was causing
a 4.25 IQ point loss in NZ, with measurable negative life
outcomes.
Of the 19 studies rated higher quality,
18 found a lowering of IQ.
The NTP recognised that
of the high-quality studies the Canadian and Mexican cohort
data were the strongest. Those studies included Bashash
2017, Bashash 2018, Green 2019, Till 2020, Farmus 2021.
Those studies found an IQ reduction range between 3 – 9 IQ
points. On average, a 1ppm increase may cause a 5 IQ point
reduction. In New Zealand we fluoridate at a range of
between 0.7ppm – 1ppm which means we could be lowering IQ
in New Zealand children by between 3 and 5 IQ points on
average. The Till 2020 IQ study was on infant formula being
reconstituted with fluoridated water and found a 9 IQ point
reduction at 1ppm.
The September 2022 draft
concluded that there was no safe threshold of fluoride in
the water, stating on page 652 “there is no obvious
threshold”.
Criticisms of the NTP report by the
fluoride promotors such as the American Dental Association
have been repeatedly repudiated by the NTP, stating clearly
that the report's conclusions were very much relevant to
fluoridated communities and pointing out that the "highest
quality studies showing lower IQs in children were done in
‘optimally’ fluoridated areas”.
Christopher
Luxon has previously said that “The National Party is
backing the science on fluoridation - no doubt about it”.
The result of this major international fluoride review shows
that both National and Labour are misguided in their blind
dogmatic support for fluoridation in New Zealand, which must
be stopped immediately.
Only 4% of the world’s
population received fluoridated water, and 98% of Europe is
not fluoridated.
The NTP is a collaboration
between the National Institute for Occupational Safety and
Health (part of the Centers for Disease Control), the Food
and Drug Administration and the National Institute of
Environmental Health Sciences (part of the National
Institutes of Health). The NTP is the Go-To agency when the
US Government want to review any “agents of
concern”.
Fluoride Free NZ has been dedicated to
promoting the true science about fluoridation since 2003 and
opposing this increasingly discredited practice.
