Can Fluoride Lower Human Intelligence?

Its The Fluoride Stupid

Is fluoride a potential cause of lowering of IQ in our children? Certainly those who advocate for consuming it therapeutically, without acknowledging its well-known adverse health effects, may themselves be suffering from a fluoride-induced deficiency of intelligence. 

After all, is it intelligent to ignore the evidence supporting a hard and fast connection between increased fluoride exposure and lower IQ? For example...

The study, titled "Fluoride and children's intelligence: a meta-analysis," published in the journal Biological Trace Element Research in 2008, set out to determine" ...whether fluoride exposure increases the risk of low intelligence quotient (IQ) in China over the past 20 years."  They reported:

Sixteen case-control studies that assessed the development of low IQ in children who had been exposed to fluoride earlier in their life were included in this review. A qualitative review of the studies found a consistent and strong association between the exposure to fluoride and low IQ. The meta-analyses of the case-control studies estimated that the odds ratio of IQ in endemic fluoride areas compared with nonfluoride areas or slight fluoride areas. The summarized weighted mean difference is -4.97 (95%confidence interval [CI] = -5.58 to -4.36; p<0.01) using a fixed-effect model and -5.03 (95%CI = -6.51 to 3.55; p<0.01) using a random-effect model, which means that children who live in a fluorosis area have five times higher odds of developing low IQ than those who live in a nonfluorosis area or a slight fluorosis area.[1]

Again, areas with the highest levels of fluoride exposure resulted in children with 5 times higher odds of developing low IQ than those in non- or low fluoride areas.

Don't trust the Chinese meta-analysis?  How about this Mexican study titled, "Decreased intelligence in children and exposure to fluoride and arsenic in drinking water," published in 2007 in the journal Cadernos de saúde pública, which found even more dramatic drops in children's IQ associated with higher urine concentrations of fluoride. [2]

Fluoride is not simply a toxic chemical, linked to over 30 adverse health effects.  It also has psychotropic properties, which is why it is used in psychiatric medications for "treating depression." Case in point: fluoxetine, a fluoride-containing drug sold by the trade names Prozac, Sarafem and Symbyax.

Drugs.com lists the following possible adverse effects on the nervous system:

Nervous System — Frequent: emotional lability; Infrequent: akathisia, ataxia, balance disorder, bruxism, buccoglossal syndrome, depersonalization, euphoria, hypertonia, libido increased, myoclonus, paranoid reaction; Rare: delusions.

The common medical definition for "emotional lability," also known  pseudobulbar affect (PBA),  is: "involuntary crying or uncontrollable episodes of crying and/or laughing, or other emotional displays" -- ironic, isn't it, that a chemical marketed as an antidepressant can cause involuntary crying? Also not exactly a rationality-promoting chemical either, is it?

Another "infrequent" side effect of this drug listed is as "depersonalization." Since fluoride has been linked to the pathological calcification of the pineal gland, the traditional "seat of the soul," the depersonalization noted as a side effect of fluoxetine exposure, e.g. "...periods of detachment from self or surrounding which may be experienced as "unreal" (lacking in control of or "outside of" self) while retaining awareness that this is only a feeling and not a reality," could represent the general soul-dislocating effects of fluoride-containing drugs, and fluoride in general, on the pineal gland and other brain structures.

Nursery Water

This is, of course, is not simply an academic question.  Companies market "Nursery Water" to new parents, designed to intentionally dose their infants with additional fluoride, even while it is well-known that many are already being overdosed with the stuff from infant formula, toothpaste, tap water-prepared food, etc. to the point that fluorosis, a fluoride-induced damage to and/or discoloration of the enamel of the teeth, can be detected in many of them.

Shouldn't these manufacturers be obligated to provide a warning to consumers: "may reduce IQ"?  Or, perhaps I am thinking too much, having neglected to take my daily dose of FDA-, EPA-, ADA- approved fluoride.

Fluoride in Tea



Yes, fluoride in tea adds to the body burden of fluoride in the body.  Drinking a gallon of regular tea each day can give you skeletal fluorosis in 10 - 20 years.  Black tea seems to be especially high in fluoride and pregnant women should not drink it during pregnancy.  An adult excretes less than 50% of ingested fluoride.  A baby excretes less than 15%.  It bio-accumulates in the body over your lifetime.  Fluoride is attracted to calcium so it will be abundant in your teeth and skeletal system.  Calcium is a fluoride antagonist.  It is used as an antidote for fluoride overexposure.  What is put in tap water however is not naturally occuring "calcium fluoride".  What is added to tap water is "sodium fluoride" minus the antagonist calcium.  This makes it more toxic to the body.  Get plenty of calcium, magnesium and vitamin C in your diet.  You can't cook fluoride out of tap water.  Nor does it evaporate.  Cooking with fluoridated tap water only concentrates it in your foods & beverages.   In America most all processed foods, beverages and fresh produce contain fluoride.  It isn't required to be labeled.   The fluoride on fresh produce comes from pesticides that contain fluoride.  Fluoride is also in the polluted air we breath.  It is absorbed through the skin when bathing, showering or swimming in fluoridated tap water.  Worse still, neither doctors or dentists monitor their patient's levels of fluoride in their hair, blood, urine, nails, bone, etc.  How scientific is that?  You can't determine a persons fluoride levels by simply counting cavities.  Furthermore, bucket medication is unscientific as you can't control the dose.  I've read that it takes months of avoiding fluoride to get the levels of it down in the body.  Some claim that increasing your intake of iodine may help remove it but I've not researched it.  Both fluoride and iodine are halogens and fluoride competes with iodine for the iodine receptors of the body and thyroid gland, and sometimes results in hyporthyroidism.  Hypothyroidism causes elevated cholesterol levels.

Flouride In Tea



Thanks for the answer

The building I'm living in now has reverse osmosis water filter for all water needs, I may need to move in the near future and I think I'll probably use aquasana whole house water filter if I move, and I guess both of the filters remove fluoride from water. I've also read ingesting borax or boron supplements work, are they really useful ?

The flouride amount really scared me out of tea, I'm still drinking some white peony tea sometimes but I won't buy anymore tea but I may try some tea extract maybe if I can assure myself that the extract is free from flouride.

Flouride In Tea



What about flouride in black/green/white tea ? They have enormous amounts of flouride, so how safe is it to consume them ?

What's the best way to detox flouride, in your opinion ? Is avoiding flouride enough to detox flouride in time ?

Floride



    And I thought you prided yourself on scientific research?   The article you are referring to is about the effects of burning coal laced with floride.  It is a real problem in China.  It also happens to mainly the really poor people who can't afford proper cooking stoves or fuel. And that probably has some effect on overall intelligence (being poor, etc).   Kind of like saying that collecting wine bottles to turn into recycling  centers leads to lower intelligence?  To try and link this to floride use in America is a huge leap.

   A good article about all of this is here  http://www.fluoridealert.org/Alert/China/Fluorosis--China-s-Poison-Plague.aspx

   Take the time to read the research behind your quick conclusions. 

   I do appreciate that you published your links, so that more research could be done.

Can Fluoride Lower Human Intelligence



Let's not forget either that the Pineal Gland regulates sleep and the onset of puberty in females.  We now have some females beginning puberty at 6 years of age.  Fluoride calcifies the Pineal Gland.

When is the CDC going to employ a toxicologist in their Oral Health Division so they can properly assess the effects of fluoride on the human body?  When they promote consuming a toxic chemical like fluoride they need to keep in mind that a human body comes attached to those teeth.  This is something they conveniently fail to account for.  Not to mention the fact that the majority of children living in fluoridated areas of the USA now have dental fluoroisis.  This is dental damage that causes mottled, pitted, and brittle teeth due to overexposure to fluoride.
