New Research Links Water Fluoridation to ADHD, Thyroid Disease
Strong research published in the British Medical Journal this week shows a significant relationship between fluoridated
water and ADHD , with each 1% increase in artificial fluoridation prevalence in 1992 being associated with approximately
67,000 to 131,000 additional ADHD diagnoses from 2003 to 2011 in the United States.
This comes hard on the heels of research published on Tuesday which demonstrated an almost doubling of the rate of
hypothyroidism in areas with water fluoridation in England.
This disease is increasingly common among New Zealand women, and has symptoms which include depression, weight gain and
Last year, a leading team of Harvard researchers classified fluoride as a developmental neurotoxicant, that is, it
affects brain development resulting in lowered intelligence.
Fluoride is added to the water supply in much of New Zealand based on advice from some dental organizations that it will
help reduce tooth decay, although the level of benefit is questionable for most people.
It is also concerning that safety monitoring of individual fluoride levels from all sources is not being monitored,
despite WHO recommendations for fluoridated communities. On the contrary, the health minister last month made water
fluoridation exempt from the checks and balances required by the medicines act, without hearing submissions.
Although a New Zealand government review of fluoridation last year declared fluoridation to be safe and effective,
questions have been asked about its lack of objectivity.
In view of the mounting body of research reinforcing health concerns of drinking fluoridated water long term, FIND calls
for these population based studies on health effects to be replicated in New Zealand, and renews its call for a
moratorium on water fluoridation until safety can be scientifically proven.
