Major Harvard study confirms fluoride lowers childrens IQ

major-harvard-study-confirms-fluoride-lowers-childrens-iq

Harvard University researchers’ review of fluoride/brain  studies published this months in EHP concludes “our results support the possibility of adverse effects of fluoride exposures on children’s neurodevelopment.  Future research should include detailed individual-level information on prenatal exposure, neurobehavioral performance, and covariates for adjustment.”

The stuy by Anna L. Choi, Guifan Sun, Ying Zhang, Philippe Grandjean was submited December 30, 2011 and published online July 20, 2012 in Environmental Health Perspectives, a US National Institute of Environmental Health Sciences’ journal (here).

“The children in high fluoride areas had significantly lower IQ than those who lived in low fluoride areas,” write Choi et al.

Further, the EPA says fluoride is a chemical “with substantial evidence of developmental neurotoxicity.”

Fluoride (fluosilicic acid) is added to US water supplies at approximately 1 part per million attempting to reduce tooth decay.

Water was the only fluoride source in the studies reviewed and was based on high water fluoride levels. However, they point out research by Ding (2011) suggested that low water fluoride levels had significant negative associations with children’s intelligence.

Choi et al. write, “Although fluoride may cause neurotoxicity in animal models and acute fluoride poisoning causes neurotoxicity in adults, very little is known of its effects on children’s neurodevelopment. They recommend more brain/fluoride research on children and at individual-level doses.

“It’s senseless to keep subjecting our children to this ongoing fluoridation experiment to satisfy the political agenda of special-interest groups,” says attorney Paul Beeber, NYSCOF President.  “Even if fluoridation reduced cavities, is tooth health more important than brain health? It’s time to put politics aside and stop artificial fluoridation everywhere,” says Beeber.

After reviewing fluoride toxicological data, the NRC reported in 2006, “It’s apparent that fluorides have the ability to interfere with the functions of the brain.”

Choi’s team writes, “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.”

Fluoride accumulates in the body. Even low doses are harmful to babies, the thyroid, kidney patients and heavy water-drinkers. There are even doubts about fluoridation’s effectiveness (2). New York City Legislation is pending to stop fluoridation. Many communities have already stopped.

Infant formula when mixed with fluoridated water delivers 100-200 times more fluoride than breastmilk.

A study published in 2011…

 Fluoride can damage the brain – avoid use in children

“The prolonged ingestion of fluoride may cause significant damage to health and particularly to the nervous system,” concludes a review of studies by researchers Valdez-Jimenez, et al. published in Neurologia (June 2011), reports New York State Coalition Opposed to Fluoridation, Inc. (NYSCOF).

The research team reports, “It is important to be aware of this serious problem and avoid the use of toothpaste and items that contain fluoride, particularly in children as they are more susceptible to the toxic effects of fluoride.”

“Fluoride can be toxic by ingesting one part per million (ppm), and the effects are not immediate, as they can take 20 years or more to become evident,” they write.

“Fluoridation clearly jeopardizes our children and must be stopped,” says attorney Paul Beeber, President, NYSCOF.  “We can actually see how fluoride has damaged children’s teeth with dental fluorosis; but we can’t see the harm it’s doing to their brains and other organs. No U.S. researcher is even looking,” says Beeber.

Valdez-Jimenez, et al. describe studies that show fluoride induces changes in the brain’s physical structure and biochemistry which affects the neurological  and mental development of individuals including cognitive processes, such as learning and memory.

“Fluoride is capable of crossing the blood-brain barrier, which may cause biochemical and functional changes in the nervous system during pregnancy, since the fluoride accumulates in brain tissue before birth,” they write.

Animal studies show fluoride’s toxic brain effects include classic brain abnormalities found in patients with Alzheimer’s disease, Valdez-Jimenez’s team reports.

A different research team (Tang et al.) reported in 2008 that “A qualitative review of the studies found a consistent and strong association between the exposure to fluoride and low IQ.” (Biological Trace Element Research).

In 2006, the U.S. National Research Council’s (NRC) expert fluoride panel reviewed fluoride toxicology and concluded, “It’s apparent that fluorides have the ability to interfere with the functions of the brain.” And, “Fluorides also increase the production of free radicals in the brain through several different biological pathways. These changes have a bearing on the possibility that fluorides act to increase the risk of developing Alzheimer’s disease.”

On April 12, 2010, Time magazine listed fluoride as one of the “Top Ten Common Household Toxins” and described fluoride as both “neurotoxic and potentially tumorigenic if swallowed.”

  1. The links to the study and the EPA don’t work. Would have liked to read the study myself. Link to Fluoride action Network worked but that seemed a little biased.

  2. Even well water and spring water is not safe anymore. Most of the water sources on our planet contain toxins of one form or another. Your best bet is to get a high end water filter that will filter out the toxins, flouride and chlorine. Also get one that adds in the essential minerals after the filtering process as the minerals get filtered out too.

    Anyone else seeing adds on this page for toothpaste with flouride???

  3. I use OralMD. It’s an natural almond, spearmint & peppermint oil based product you can buy online. I have no connection to the company or product.

  4. What is even more unscientific is the whole idea of adding nutrients to WATER.. the bulk of which is used to flush toilets, irrigate gardens, fill swimming pools or use in industries. IF (and that’s a great IF) you need fluoride, then make sure the food you eat contains it or if there’s really a problem, consider a supplement. But in the WATER? Why then not add vitamins to the water supply?

  5. Duh…something we have known for years, and they are just now starting to notice that?
    Oh well, better than never. By the way, it is so hard to find toothpaste without fluoride…I can walk into a store and there’s shelves full of toothpaste and there are maybe one or two fluoride-free toothpaste.

  6. Just pick the correct toothpaste, NON-floride, drink spring, or well h2o,
    and avoid this toxin. EDUCATE your friends.
    This needs to go around the world.
