fluorideiq 235x147 Breaking: Major Harvard Study Published in Federal Govt Journal Confirms Fluoride Lowers IQ

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 Perspectivesa 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.

In regards to the last breaking study, Connett stated:

“In this study we found a significant dose-response relation between fluoride level in serum and children’s IQ…This is the 24th study that has found this association, but this study is stronger than the rest.”

Will the latest Harvard-backed study be ignored by major public health organizations, or will serious change be initiated?

    This is what you consider reliable? A study of 32 other studies, 8 of which had to be thrown out for incomplete information, that attempt to digest a result from dozens of different methodologies, more than 2 different sources of different kinds of flouride, children of indeterminate age, IQ's not adjusted for development… The subjects were two different geographical regions (china and iran) and ALL of the studies that this study studied have listed discrepencies, missing information, and points of confounding. This isnt research, this is a digest trying to get people to go out and actually do research.

    Re: Seriously?
    "The average loss in IQ was reported as a standardized weighted mean difference of 0.45, which would be approximately equivalent to seven IQ points for commonly used IQ scores with a standard deviation of 15.*"

    Seven IQ points strikes me as meaningful as well as significant.

  • Brandon

    Don't believe anything you read or anything that is published or stated in the media, internet or whatever. It's all lies.. We're being force fed a multitude of information from everywhere and everyone. Eventually we'll all pay for what we are doing to ourselves and the "people in charge" are just laughing at us, as we are the lab rats. We're the test subjects.. head my warnings. We're our own worst enemies.

  • Chris

    PS – for 'gisellewilding' – yes, fluoride and aluminium both have physiological roles. They are involved in the physiology of G-proteins, which are essential for intercellular communication in multicellular organisms like us.

    Scientists who discovered and investigated G-proteins won Nobel prizes in 1994 and this year.

    From an evolutionary standpoint it ought not be surprising that we have incorporated highly reactive elements like F and Al into our physiology.

  • Chris

    This is not a very impressive meta-analysis. As has been pointed out, there are loads of possible confounders; the 'significant' finding is statistically but not clinically significant; and in any event the study is correlational.

    Your trumpeted conclusions are not warranted.

  • gisellewilding

    Can anyone tell me if any living creature has fluoride in any of it's naturally occurring molecules?

    It is good to have nice teeth but I would put good teeth way below a healthy brain;missing limbs; blindness; melanoma or many others of the horrors this substance we KNOW causes and no bearded boring nerds please respond.You give me a headache.

  • Lolli S

    There is no doubt that fluoridation of water is bad for us. There has been much evidence of this. I have read many articles on studie that have shown the harm to teeth as well as the rest of the body. When will we wake up and stop poisoning our water. Water is our life force. Let's make it pure, not contaminated.

    • Jakenow

      Lolli — You write that there is "much evidence" that fluoridated water is bad. So where is all of this evidence that you claim is out there? I believe in eating well, reducing toxic exposures, etc., but I'm not willing to jump on the "crazy train" of attacking fluoridation. My teeth are a whole lot healthier than my parents' teeth were, and fluoridated water is the key reason why that is.

      • David Smith

        I don't know why this study alone isn't enough for you. The thought of your IQ plummeting should be enough to get you to change your mind. If you want more proof go to http://www.fluoridealert.org/issues/health/.

        There is tons of research and documentaries out there. You have to be willing to look for it. There is a good book called the Fluoride Deception by Christopher Bryson. You can youtube him if you don't feel like reading the book.

      • toms

        Well maybe your teeth is better than your parents but your IQ is REALLY lower then theirs. So if you care more about stupid teeth -drink and use fluoride..i won't.

      • toms

        Also your knowledge about fluoride is VERY poor. What caused the fluoridation of water in US? Big companies had to dispose many tons of fluoride as it's waste of today's many processes in fabrics, so they because of their money got people in congress and congress told a lie to people oh god you really need fluoride in water for your health!!! and companies instead of paying to get rid of fluoride -now gets money for selling it.. WASTE… THAT's WASTE! and you drink it? Choride is used to kill bacteria but fluoride is bullshit.

      • James Jackson

        Your teeth aren’t healthier because of fluoridated water. If you look it up you will find that fluoridated water only has an effect on children up to the age of 12. There is no evidence that shows fluoridated has an effect on anyone above the age of 12.

    First off this is a correlational study, and you can't claim causation from that alone. In a double-blind placebo-controlled study, you could test whether Flouride in drinking water CAUSES a decrease in IQ or not. This study only looks at a pre-existing relationship and offers a potential explanation. Keep in mind other differences between regions, like SES, education, nutrition, pollution, etc that could account for the difference. Until these are ruled out, dont stop using toothpaste–which has a causal relationship with preventing cavaties.

      Do you eat your toothpaste??? . I think you've been drinking to much fluoridated water or maybe you do eat your toothpaste. I think you've been drinking a little too much of the water

      • Steve

        Toothpaste is absorbed through the pallet and into the bloodstream, FYI.

    • Richard Rowell

      What about the problem of fluoridation added to drinking water? I thought major toothpaste companies warned against swallowing fluoride. Although this is a separate issue I see this as related, and even if it's a correlation shouldn't we not take it until it is proven that is not actually an aluminum waste byproduct?

      –Taxpayer

      • Jakenow

        Richard – Let's not get hysterical. Almost anything (including Vitamin D and calcium) can have negative health effects if it's consumed in unusually high quantities. That's why the advisory is placed on tubes of toothpaste — to encourage parents to supervise their kids' tooth-brushing so they don't swallow it. That's a basic precaution just to err on the side of limiting exposure. We should welcome this advisory, instead of citing it as a reason to be scared of fluoride toothpaste.

        • David Smith

          But Fluoride is bioaccumulative. Its been found to accumualte in the pineal gland at up 21,000 ppm causing calcification. And your Pineal gland is said to act as a biological clock signaling the onset of puberty.

    • David Smith

      You don't have to stop using toothpaste all together. You can switch to a fluoride free toothpaste as a safety precaution and above all a healthy diet. If you are constantly consuming unhealthy snacks that degrade your enamel there is no amount of fluoride that will save you. And I think we need to be more specific when discussing fluorde. We are not talking about Calcium fluoride found naturally in nature we are talking about sodium fluorde a toxic substance that your body has no need for.

    • David Smith

      "Until these are ruled out, dont stop using toothpaste–which has a causal relationship with preventing cavaties".

      This so called ruling out you are waiting for may never take place while damage is being done. Keep in the mind the government allows fluoridation to be added to toothpaste and tap water. This is the same goverment that allowed oil companies to add lead to gasoline which caused brain damage to little kids. They can make mistakes. It is up to each and every single one of use to take charge for our own health because our goverment obvioulsy doesn't. Even if there was a safe limit for fluoride we have surpassed it a long time ago. Fluoride is everywhere. Its in toothpaste tapwater and everything grown in tapwater and any processed foods in the grocery store that use tap water. Think for yourself man

    • David Dangle

      Doesn't hurt to be safe than sorry. You don't have to stop using toothpaste altogether. Just buy a fluoride free toothpaste which is much better than regular toothpaste anyway. The best thing you can do is switch to a healthy diet. If you are eating unhealthy processed sugary foods and drinking soda there is no amount of fluoride that will help you. Water fluoridation gives people an excuse to neglect their oral health.

    Seriously? … You do realize that the term "significantly lower IQ" means "STATISTICALLY significant lower IQ"… Just from the Results in the abstract: "The standardized weighted mean difference in IQ score between exposed and reference populations was -0.45 (95% CI -0.56 to -0.35) using a random-effects model."

    That means that the difference in IQ, while significant, was only -0.45… hardly a meaningful variance, even if it is significant…

    • Anonymous

      Those are standard(Z) scores, not IQ scores.

      REPLY TO ANONYMOUS: Excuses excuses. Read the Harvard meta. "Significant" meant a seven to 10 point drop in IQ. Read the Dartmouth studies by Masters, which found corrrelation between SiF (silicofluoride) and VIOLENCE. Read the materia medica on fluoric acid, the traditional medical reference work: It causes alienation, hypersexuality, alcoholism, allopecia, cancer, caries of the bone an a host of other afflictions. It's so corrosive they have to use platinum lined fittings. It eats through glass, it crosses the blood brain barrier and drags lead from your pipe fitting in with it. Where do you think all this cancer, divorce and cancer is coming from?

      • Jakenow

        If the fluoride additive "eats through glass" as you claim, then every time a person in a fluoridated city pours tap water into a glass, the glass must break.

        If that were really happening, we would know about it because most of us have friends or family who live in a fluoridated community. It would have made the local news because they are always looking for sensational stories like that.

        Do you realize how illogical that claim is? Next you'll try to blame fluoride for Hurricane Sandy.

        • David Smith

          My friend your the one that doesn't make sense. In its purest most concentrated form flouride probably could eat through glass. Its obviously not going to do that at 1ppm dissolved in tap water. The concentration is too low.

  • Johann

    I read the referenced Harvard study on nih.gov. It's only 17 pages and pretty readable. Seems like real results by real scientists, not crackpot claims by people in tin foil hats. I'm convinced fluoride lowers IQ.

    Here's a scary pair of quotes:

    From the study:

    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 (Varner et al. 1998)

    From colgate.com:

    Colgate® PreviDent® 5000 Booster Prescription Strength Toothpaste (Rx Only)

    Important Safety Information:

    PreviDent 5000 Sensitive (1.1% Sodium Fluoride, 5% Potassium Nitrate) is a dental caries preventative and a sensitive teeth toothpaste for patients 12 years of age and older.

    1.1% = 1100 ppm ~= 1000X higher than the rat-brain-altering amount.

    YIKES.

      Fluoride is a POISON, and MUST be OUT of water!

      Johann, please give the link to the study on nih.gov. I could not find it. Thanks!

  • Alex

    By the way, do some research on environmental fluoride. Fluoride has been shown to bond with calcium in nature, which makes it less dangerous.

    Yet, the industrial-grade fluoride in the tap water (a by-product of aluminium manufacturing) is quite hazardous indeed.

    I filter my water with fluoride filters, and you should too. Let's get this gunk out of the tap water.

    • Lolli S

      where did you get your fluoride filters? i have been searching for some.

      Sorry Linda to shatter your illusion! BUT there is NO safe and beneficial fluoridation to our water supply.. The fluoride that is used is NOT like it is in nature. Do some research yourself.

    • joe nobody

      As a research scientist, I guessed the same thing. I presumed they were not talking about toothpaste and mouthwash, but significantly higher levels, toxic levels, beyond that which is normal.

      • jennifer

        research scientist…"I guessed" and "presumed"? I "guess" and "presume" that you work within the system that is poisoning this country! The NIH site states that .7 is the "accepted" dose yet water is contaminated with fluoride at 1 ppm…the facts are right in front of us folks! How about the connnection between Alheimers/dementia and aluminum? Isn't fluoride a "by-product" of aluminum? Follow the money trail kids!

    Over 300 communties have decided to reject fluoridation in the last 10 to 15 years.

    Only 5% of the world uses fluoridation because many large studies in Arizona, in New Zealand, in India, and in Japan show fluoridation is totally ineffective in improving tooth decay and is dangerous to health.

    The World Health Organization studied 16 countries and showed fluoride is of no value for teeth. All of the major countries in Europe, except Ireland, have considered and rejected it, and so Europe is 98% fluoride free. In addition, India, Japan, China and most countries now reject it.

    Read the best scientific information on fluoridation in Dr. Paul Connett's book, "The Case Against Fluoride," published last year. It contains over 1200 peer reviewed studies and sound scientific reasoning showing the ineffectiveness and dangers to health from fluoride. Also presented is scientific evidence to show that it causes cancer, thyroid & pineal gland damage, broken hips from brittle bones, lowered IQ, kidney disease, and other serious health problems.

      Anyone can write a book and provide references with cherry picked data… but to publish a peer reviewed paper in which your hypothesis is clearly shown to hold water.. Well, that is where the true test comes from.

      Let's see you provide a paper that says fluoride is harmful at .5-1.0mg/l. I am willing to bet you can't and that you believe everything you read in books that provide 'references' and see in documentaries.
