New Study Finds Fluoride Exposure Correlated To Lower IQ

Content originally published at

Researchers in Toronto, Canada have published a peer-reviewed study in Environmental Health Perspectives which finds that increased exposure to fluoride in utero is associated with lower IQ in children.

X-axis: fluoride exposure in utero, Y-axis: IQ

In a study spanning more than a decade, the researchers analyzed 1,576 samples from nearly 300 sets of mothers and children in Mexico where fluoride is not added to public water supplies, and is instead absorbed through naturally occurring concentrations in public water and fluoridated products. The IQ of children included in the study was tested twice up to the age of 12, which revealed a decrease in IQ scores for every .5 milligram-per-liter increase in fluoride exposure beyond 0.8 milligrams per liter of a pregnant mother's urine. 

What about exposure out of the womb?

While the Canadian researchers did not find a correlation between fluoride intake and lowered IQ once a child was born, there have been over 50 studies on the impact from the industrial byproduct on the human body as of September 2016.

CNN reports "Previous studies have found fluoride to be a potential neurotoxin at extremely high levels. Many of these studies have been conducted in China, where fluoride levels in water can be as high as 30 milligrams per liter. The Environmental Protection Agency has set a limit of 4 milligrams per liter."

And in a 2012 meta-analysis of 27 such studies published in Environmental Health Perspectives, researchers from Harvard School of Public Health (HSPH) in conjunction with China Medical University in Shenyang reported that 'fluoride may adversely affect cognitive development in children,' adding 'children in high-fluoride areas had significantly lower IQ scores than those who lived in low-fluoride areas.'

“Fluoride seems to fit in with lead, mercury, and other poisons that cause chemical brain drain,” said Harvard researcher Phillippe Grandjean. “The effect of each toxicant may seem small, but the combined damage on a population scale can be serious, especially because the brain power of the next generation is crucial to all of us.”

In  a follow-up study, the Harvard-led research team concluded that 'fluoride in drinking water may produce developmental neurotoxicity.'

"Results of our pilot study showed that moderate and severe dental fluorosis was significantly associated with deficits in WISC-IV digit span. Children with moderate or severe dental fluorosis scored significantly lower in total and backward digit span tests than those with normal or questionable fluorosis. These results suggest a deficit in working memory." -via

It's not a communist plot. It's a plot by big corporations and crooked governments/deep state. Flourides are actually a by-product from refining aluminium. So they found a clever way to make extra $$ from that instead of having to pay for storing it somewhere. Putting it inot water and into toothpaste. there is a reason why small children and babies must not be exposed to flour-enriched tootpaste.

Lower IQs in the African population (in general, not all) are scientifically proven to be genetic. The ignorant or devious liberal left excoriated book “The Bell Curve” is accurate.   But on a lighter note, it is indeed a Communist plot... Precious Bodily Fluids

In California, the corrupt government in Sacramento decided to force fluoridation on all larger cities as a legal requirement.This article forgot to mention the use of fluoride by Hitler in the concentration camps in order to help keep the prisoners docile.  Then our government hired a "scientist" to perform a study concluding it was good for us.  All of a sudden, all that toxic waste became a financial asset rather than a liability. Follow the money.

You have to be smart enough to get this:TPTB don't give a flying fuck about your teeth.They do care about having a compliant population. Ponder this:What is the proper dosage for fluoride taken orally?Should you monitor your child's water intake to make sure they aren't getting an overdose of rat poison? Think about all the Democrat Voting Plantations aka big cities.They all have fluoridated water. The JBS was right after all.

Flourine is the most electronegative element in the periodic table. Which means that it forms strong ionic bonds with intercellurarly and accumulates. That's the most insidiuous part of it. The effects are cummulative and ceasing exposure does not reverse the effects.

I have to wonder what the effects of chlorine are, given that it has similar chemical properties.The water where I live has no fluorine in it, but plenty of chlorine.  Chlorine will dissipate if you let the water stand in an open container for a few hours, but some people drink it straight out of the tap.  That can't be good.

My friend is a scientific researcher who studied floride's effects on rats at the university that originally did the early floride research upon which public policy was based. He uncovered a major flaw in how many previous studies were conducted. Rats were put in wire cages that were stacked like highrise condos. Each cage was carefully labled and each tier of rats was given a different dose of floride which was laced with a radioactive tincture of inulin. This method of storing rats had been used for many years and many scientific papers were published using the results of measuring the various levels of floride in these stacked rats.

The problem my friend discovered, and no previous researcher had noticed or understood was that the rats' droppings in the upper cages fell down into the lower cages. The rat droppings were rich in this inulin tracer. The lower tiered rats ate the shit of the rats above them. This meant that there was no way to tell how much inulin, and thus floride, the rats had in their system that came from the controlled dosing vs the eating of droppings. Yet public floride policy was made on the basis of many deeply flawed studies.

My friend presented his findings at a seminar that included a few professors who had based their careers on these flawed studies. No paper was published to protect the guilty. The department head who oversaw this mess retired and died of a heart attack within a year. My friend said this department head had looked like he was having a heart attack when he sat in the seminar and absorbed what it meant.

Na a poison..toxicology texts list it that way. but then why put it in anything we consume?  well it's good for teeth or they will find Lead is good for anemia..and so ..heavy metal's ain't never good for you, much like war.

/~~~~~~~~~~For many years now, we at Night Hawk Minerals have been working with natural radiation hormesis using stones that we mine that emit a low dose of radiation. This is called "Radiation Hormesis" and is an old, but extremely effective healing modality. I would encourage those that are dealing with a degenerative disease, such as cancer, to go to our website, , and research "Radiation Hormesis". We have worked with some of the best nuclear physicist and doctors in the world and could go on for days about the success we have had just using "radiation hormesis", and more importantly what we have learned, but what we are going to do is go over the 3-Divine Protocol.\~~~~~~~~~~There is a whole "science of hormesis" out there. These people claim that tiny amounts of poison are good for you. Although there are of course exceptions (you do need a trace amount of selenium), this is yet another fake science. Of course it's cheaper to just hit your head with a rock every day."Big cats are dangerous but a little pussy never hurt anybody."

This is a handy explanation of why 4 out of 5 dentists commit suicide! But seriously, quoting studies from China and Mexico?!?! WTF Please name 3 Mexican intellectuals...I've known two, that might qualify. I was born in east LA, am on the tail end of the boomer generation (1960 vintage), lived most all my life less than a 150 miles from our southern "friends", and have suffered hispanics all my life. I seriously endeavor to NOT be racist (experience makes it a bitch!), my Pops was, and I try to be better.   I guess the prevalence of naturally occurring (industrial byproduct?) fluoride in drinking water would explain the correlation of perfectly good pavement and the preference to park one's automobile on the lawn? That and shiny VW wheels on a $500.00 Chevy while your 14 children are barefoot and you live in a tar paper shack, with another 30 or so relatives, sharing one bathroom, and everyone refusing to flush the paper down the toilet! Further,I strongly suspect that this correlates / influences the preference of hispanic females for Raid scented fragrances in gagging (maggot off a shit wagon at 50 yards) quantities! Priorities, not doubt (s). The Chinese, ever wonder why they were called "celestials" in the late 1800's? I do not believe it was due, solely, to the fact that they were non christians. Personally, I believe it had more to do with the lack of ethics, or respect for any one or thing other than themselves. They endured a great deal of racism due to their "soul less" behavior/customs, even worse than the zionists imho. Seemingly, similar behavior today. I'm still waiting for / seeking a rational explanation for the Indian (India) people. It took quite a while for me to comprehend the phrase "irrational" when referring to a race, having little personal interaction. Well, it did not take too much interaction to begin to get it. When seeking lodging... if the joint reeks of curry, best keep moving. I don't believe they even get it! Bottom line, people are random, friends, family and strangers. Take em one at a time, don't prejudge. Fluoride is an ugly element, but not an excuse. Show your Mom and Pop they were right, be better than them.
