It's great that it whitens your teeth and protects you from holes in them... except that it affects your brain and that of your children, eh?

"The movement to remove industrial sodium fluoride from the world’s water supply has been growing in recent years, with evidence coming out against the additive from several sources.

Now, a report from the world’s oldest and most prestigious medical journal, The Lancet, has officially classified fluoride as a neurotoxin, in the same category as arsenic, lead and mercury.

The news was broken by author Stefan Smyle and disseminated by the Facebook page Occupy Food, which linked to the report published in The Lancet Neurology, Volume 13, Issue 3, in the March 2014 edition, by authors Dr. Phillippe Grandjean and Philip J. Landrigan, MD. The report can be viewed by clicking here.
Industrial Chemicals Identified

As noted in the summary of the report, a systematic review identified five different similar industrial chemicals as developmental neurotoxicants: lead, methylmercury, polychlorinated biphenyls, arsenic, and toluene.

The summary goes on to state that six additional developmental neurotoxicants have also now been identified: manganese, fluoride, chlorpyrifos, dichlorodiphenyltrichloroethane, tetrachloroethylene, and the polybrominated diphenyl ethers. The authors added that even more of these neurotoxicants remain undiscovered.

ADHD, Dyslexia, and other cognitive impairments

In the Lancet report, the authors propose a global prevention strategy, saying that “untested chemicals should not be presumed to be safe to brain development, and chemicals in existing use and all new chemicals must therefore be tested for developmental neurotoxicity.”Also in the report, they note that neurodevelopmental disabilities, including attention-deficit hyperactivity disorder, dyslexia, and other cognitive impairments, are now affecting millions of children worldwide in what they call a “pandemic of developmental neurotoxicity.”

They continue: “To coordinate these efforts and to accelerate translation of science into prevention, we propose the urgent formation of a new international clearinghouse.”

The report coincides with 2013 findings by a Harvard University meta-analysis funded by the National Institutes of Health that concluded that children in areas with highly fluoridated water have “significantly lower” IQ scores that those who live in areas with low amounts of fluoride in their water supplies.

Fluoride also linked to Cancers

Sodium fluoride in drinking water has also been linked to various cancers. It is functionally different than the naturally-occurring calcium fluoride, and commonly added to drinking water supplies and used by dentists and in dental products who posit that it is useful for dental health.

Currently, fluoride is added to water supplies across much of North America, but as this list of countries that ban or reject water fluoridation shows, the practice is actually not too common, or banned entirely throughout most of Europe and in several other developed nations across the world."

" A recent report from the U.S. National Research Council (NRC 2006) concluded that adverse effects of high fluoride concentrations in drinking water may be of concern and that additional research is warranted. Fluoride may cause neurotoxicity in laboratory animals, including effects on learning and memory ...

To summarize the available literature, we performed a systematic review and meta-analysis of published studies on increased fluoride exposure in drinking water and neurodevelopmental delays. We specifically targeted studies carried out in rural China that have not been widely disseminated, thus complementing the studies that have been included in previous reviews and risk assessment reports ...

Findings from our meta-analyses of 27 studies published over 22 years suggest an inverse association between high fluoride exposure and children's intelligence ... The results suggest that fluoride may be a developmental neurotoxicant that affects brain development at exposures much below those that can cause toxicity in adults ...

Serum-fluoride concentrations associated with high intakes from drinking-water may exceed 1 mg/L, or 50 Smol/L, thus more than 1000-times the levels of some other neurotoxicants that cause neurodevelopmental damage. Supporting the plausibility of our findings, rats exposed to 1 ppm (50 Smol/L) of water-fluoride for one year showed morphological alterations in the brain and increased levels of aluminum in brain tissue compared with controls ...

In conclusion, our results support the possibility of adverse effects of fluoride exposures on children's neurodevelopment. Future research should formally evaluate dose-response relations based on individual-level measures of exposure over time, including more precise prenatal exposure assessment and more extensive standardized measures of neurobehavioral performance, in addition to improving assessment and control of potential confounders."

So now we know why there are so many stupid people out there, without them ever recognizing it? lol

The substance is long of a big concern. Good that something keeps moving with that situation.

[poser765]

Obligatory.

Children IQ?

So grown ups are immune to neurotoxins?

[Lothaeryn]

Well, if this is true, it would explain the increased diagnosis of ADHD cases over the past few decades.

Also, potential lawsuit goldmine if it is confirmed by other sources as well

Everybody and his male dog has ADHD the increased diagnosis rate of ADHD is because nobody dragged their son whos bad in school to the doctor and get a diagnosis before it was trendy.

What you lose during your childhood... Effects everyone. Effects kids more though, since the brain is part of the entire body. And we grow until around the age of 18.
IF you lose a percentage of your braincells during that timeline, your capacity is limited from the get go.

I tend to agree with this somehow....
The amount of "Disorders" exploded literally.... There's nowadays a term for anything and everything, and by that, pretty much every person has some sort of a disorder, they can fall back at, as an excuse...
Excuse, yes. Because else I have no damn clue how we've gone through tens of thousands of years without ever noticing...

Increases in diagnosis does not equate to an increase in cases. Cancer rates are going down, but we tend to diagnose it more often because modern medicine enables us to identify it sooner rather than later. So cancer is being detected faster and more frequently than it was in the 50's but cancer rates are declining.

It's always been known that Fluoride (note spelling) is toxic at extremely high levels, way beyond what is added to the water supply. But by all means, let's get rid of stuff added to our food sources because of insane conspiracy theories. Worked so well in Pakistan

[Garnier Fructis]

Can someone who has a clue read the Harvard meta analysis and report back the non-sensational version? Because I'm pretty sure Eatlocalgrown is not the place to go for a clue.

[Masark]

More absurd spewing.

All the papers they reference are about HIGH fluoride levels. i.e. places with naturally occurring fluoridated water with levels are higher than what is added to water artificially.

The recommended level of fluoride in drinking water in the USA is 0.7mg/l, and a maximum of 4mg/l. The China study involved drinking water with up to 11.5mg/l of fluoride. For the math-impaired, that's almost 2.5x the maximum allowed concentration in the USA and over 16x the recommended level.

Also, many European countries don't fluoridate their water. They fluoridate salt.

The Lancet also published (and later retracted) a paper that concluded Autism was caused by vaccinations. I will remain skeptical of this news about sodium fluoride until further research has been published by other peer-reviewed journals.

"High fluoride levels are bad, m'kay?"

The fluoridation that is done to water isn't nearly as high as the levels they're talking about, iirc.

[ComputerNerd]

I call scaremongering.
Given how this "evidence" is not via any established news or scientific establishment then I have a hard time believing it.
Plus Masark makes a compelling argument about the quantities being way above the values you would see in controlled use.

Fluoride occurs naturally in water supplies, some places have higher levels of natural fluoride contamination than others.

You should actually read the study, which I did read a Chinese study on the IQ effects from fluoride and arsenic contamination, and although it did in fact show that high levels of fluoride contamination did cause IQ loss compared to the control group, the control group actually included fluoride levels that are slightly above the average level of recommended fluoride in fluoridated public water sources in the US.

And the disparity between fluoride in the high fluoridation water source and the control group was so massive that there is virtually no comparison.

Does fluoride have an effect on IQ? Yes. But it's difficult to determine what kind of an effect fluoride levels that are recommended and maintained by US water system are. Did you actually look at the study and see what fluoride percentages were used in the control group compared to the high fluoride levels? I'd recommend that you do.

QFT, that's exactly what the Chinese study I saw read. They showed massive naturally contaminated fluoride water supplies and the control group they used was closer to the recommended level of fluoride in the USA. So how do you support the assessment that the recommended fluoride levels in the US cause cognitive impairments when the control group in the study you're citing has the recommended levels of fluoride?

[Super Kami Dende]

got to love the scaremongering of idiots in the world.
It is toxic in a high dosage, the amount in water is at a minuscule level. It would be like people blaming eating fish on mercury poisoning.
Even though there is mercury in Fish, it isn't at a high enough concentration to affect us enough to be an "adverse" effect.

[ShimmerSwirl]

People have been saying this for years.

^this, so much this.
And they've be saying that with as much frequency and evidence as how aliens are among us, which we should fear too.
Listen and believe in the people.

[Butler to Baby Sloths]

This just in, drinking water with 3-4 times the recommended amount of a substance is bad for you. Lucky for us that drinking water's cation and anion content is regulated at the processing plant, and that this is therefore totally irrelevant.

[Afrospinach]

Oh man, I used to chow down fluoride tablets when I was a kid.

They tasted great too, I should have stuck to the lead paint.
