Harvard Study Confirms Fluoride Lowers IQ

Post by expandspanos »

If the scientific link between fluoride exposure and a noted decreased in IQ is a conspiracy theory, then perhaps the Harvard researchers who just confirmed such a link should be tarred and feathered by the ‘evidence-based’ medical media. In a telling review of a variety of studies that have demonstrated just how significantly fluoride can damage the brain and subsequently your IQ, Harvard University scientists stated ”our results support the possibility of adverse effects of fluoride exposures on children’s neurodevelopment.”

The most outstanding component to the study is where it was published. Authors published their conclusion online in the July 20th edition of the prominent journal Environmental Health Perspectives, a federal government medical journal stemming from the United States National Institute of Environmental Health Sciences. The very same government that has continually asserted that water fluoridation is both perfectly safe and ‘effective’ at aiding the health of citizens who consume it on a daily basis.

In the past, the US government has actually been forced to call for lower fluoridation levels as previous research had also drawn a link between fluoride exposure and a host of neurotoxic effects. In the latest research by Harvard, it is made even more explicitly clear just how toxic fluoride can be to the body. In a written statement, researchers state:

“The children in high fluoride areas had significantly lower IQ than those who lived in low fluoride areas.”

Fluoride Lowers IQ, Sparks Tumor Growth

This should come as no surprise to those who have followed fluoride research over the past several years. As far back as 1977, for instance, epidemiological studies performed by the head of the Cytochemistry Section at the National Cancer Institute Dr. Dean Burk revealed that fluoride exposure led to increased tumor growth – even at levels as low as 1 ppm (the standard for United States drinking water). Beyond revealing an accelerated tumor growth rate of 25% in his research, fluoride was found to produce melanotic tumors, transform normal cells into cancer cells and increases the carcinogenesis of other chemicals.

In 1977, Dr. Burk estimated that fluoridation has actually caused about 10,000 deaths according to his research.

It will come as no surprise, then, that even the EPA — an agency charged with protecting the people — has classified fluoride as a substance with ”with substantial evidence of developmental neurotoxicity.” Perhaps the EPA is also run by blubbering conspiracy theorists. In another entry by study authors, it is explained how fluoride actually attacks the brain in unborn children and essentially launches a direct assault on their neurological development:

”Fluoride readily crosses the placenta. Fluoride exposure to the developing brain, which is much more susceptible to injury caused by toxicants than is the mature brain, may possibly lead to damage of a permanent nature.”

But will the United States government answer to the study? As mentioned, many studies have exposed the same correlation of IQ-crushing fluoride intake. Paul Connett, Ph.D. and director of the Fluoride Action Network was one of the many activists to speak out regarding the last study to highlight the association. And what was done? Unfortunately, it was brushed under the rug by mainstream health organizations who continue to assert that fluoride is perfectly safe. Some even recommend supplementing with fluoride pills.

EX man, the study obviously didn't "confirm" that Fluoride lowers IQ. It appears to be a review of previously published observational studies. As noted before, observational studies cannot infer cause and effect. In any case, these are the authors' stated conclusions:
The results support the possibility of an adverse effect of high fluoride exposure on children’s neurodevelopment. Future research should include detailed individual-level information on prenatal exposure, neurobehavioral performance, and covariates for adjustment.
Underline added for emphasis. They didn't claim that they had confirmed a cause and effect relationship between fluoride exposure and lower IQ. They said their results showed there is a possibility of that.

Also, the mean degree to which they estimated that IQ would be reduced is in the range of about 1/2 to 1/3 of a point. The 95% interval is –0.56 through –0.35. Not that I like the idea of ANY IQ decrease. But that's a very minimal effect if it even exists.

Finally, I have to say that I am not sold on meta analyses where somebody takes the results of previous studies and attempts to combine them. They've come into vogue recently but I'm not real high on them.

A Harvard study confirms that CS.com threads with expandos and JSO as the two opening posts have the potential to become surreal.

Let's see...a possibility of a 130 or so vs. a 130.5 or so IQ or....

I think my decision is made. That's IF there's really any decision involved.

You can still brush your teeth, floss, and visit the dentist without fluoride in the water.

Or are you one of those people who do none of the above... and, thus why we need fluoride in the water? :lol:

Personally, I floss and brush several times per day. Usually at least after lunch and after supper and usually more than that. I wish I'd have been like that when I was like 15 to 25. That's when I used to go out and party, get the munchies, eat a bunch of fruit pies or whatever, then crash without brushing my teeth.

But it's been experimentally shown that fluoride reduces the risk of tooth decay. It takes a while to find information on the experiments Googling because there is so much "noise" out there from anti fluoride people. But it's out there.

So in this case you basically have very solid experimental evidence on the one hand that confirms that fluoride reduces the risk of tooth decay and on the other hand you have this meta analysis of observational studies where the authors conclude that there is a possibility that fluoride MAY reduce IQ of children exposed to it in high doses at an early age by about 1/2 of a point on average.

I'm not arguing that fluoride doesn't reduce tooth decay.

I'm saying if you are a person that brushes their teeth... the benefits of the tiny amount of fluoride in the drinking water are negligible. The benefits are for people that do not take care of their teeth... so, they get SOME protection from tooth decay.

Another time I'm a bit surprised by your position. You think government should be putting chemicals in everyone's drinking water to coddle those (overwhelmingly poor) that don't take care of themselves? :coffee:

I was thinking more of fluoride in toothpaste, dental rinses, etc. If I could go back in time and make sure that I used those from the time I first sprouted permanent teeth I would definitely do it.

If somebody wants to stop putting fluoride in water due to cost I'm fine with that. It's just that you wouldn't be talking about a lot of money in the grand relative scheme of things and I'm not concerned about fluoride being added to the water being a hazard to me or my children. I found one article saying that the cost of fluoridating water ranges from about $0.50 per person per year in large communities to about $3 per person per year in small communities (http://www.wda.org/wp_super_faq/how-muc ... ation-cost" onclick="window.open(this.href);return false;). If you go with $3 per year to estimate what it'd cost to fluoridate water for a population the size of the United States population you're talking about around but a little short of $1 billion per year nationally.

Maybe after they eliminate all the War on Poverty Programs, Social Security, and Medicare I'll start worrying about the cost of fluoridating water supplies. But maybe not. One thing about it is that it's a program targeted for the community in general and not to specific groups deemed to "need help." And that's consistent with my belief that if we're going to have a government program anybody who wants to should be able to use it. There shouldn't be any such thing, to me, as a government program that says if you make too much money (for example) you can't receive the benefits. To me fluoridation of water supplies is basically like a public infrastructure issue. It's not an income transfer.
