Health New Zealand/Te Whatu Ora is still fining local government bodies $200,000 for not adding fluoride to their water supplies, yet even CNN in the US is stating it's a neurotoxin.
"A rigorous nine-year research review looking at the relationship between fluoride and intelligence in children concludes that as fluoride levels rise, IQ drops.
Every 1 part per million increase in fluoride in urine — a way of measuring all the sources of fluoride a person consumes — was associated with a roughly 1 point drop in a child’s IQ score, the review concluded.
Although an impact like that may seem small for any one person, on a wider scale, the study authors note, the consequences are significant, especially for those who are vulnerable because of risk factors like poverty and nutrition.
“A 5-point decrease in a population’s IQ would nearly double the number of people classified as intellectually disabled,” they write in their conclusions."
