Fluoride Can Reduce A Child’s IQ Confirmed by Harvard Study

Fluoride Can Reduce A Child’s IQ Confirmed by Harvard Study

Harvard University recently published a meta-analysis which was funded by the National Institutes of Health or NIH.  Based from the results of the study, the researchers concluded that those children living in areas with high fluoride water have significantly lower IQ scores than children who live in low fluoridated areas.

The 32 page report can be downloaded for free in the Environmental Health Perspective site.  The researchers mentioned that the report from the US NRC or National Research Council in 2006 stating that high fluoride concentrations in the drinking water have adverse affects that warrants concern and additional research.  Studies showed that fluoride can cause neurotoxicity in the laboratory animals, including effects on memory and learning.

The researchers summarized the existing literature and performed a systematic meta-analysis and review of published studies on increase exposure on fluoride in the drinking water and its association with neurodevelopmental delay.  They specifically targeted the studies that were done in rural China which has not been widely disseminated.  This further complements the existing studies that are already included in the risk assessment reports and previous reports.

The findings from the meta-analysis of the 27 studies published for a period of 22 years suggest an inverse association existing between children’s intelligence and high fluoride exposure.  The study has shown that fluoride can be a developmental neurotoxicant that may affect the brains proper development at the level of exposure which is below than those that cause toxicity in adult population.

The concentrations of serum-fluoride is associated with high intakes of fluoridated drinking water that  may exceed 50 Smol/L or 1 mg/L, which is more than 1000 times the level of other neurotoxicants that can cause neurodevelopmental damage. To support their findings, experimental rats were exposed to 50 Smol/L or 1ppm of fluoridated water for one year.   The result showed alterations on the morphology of the brain and high levels of aluminum found in the brain tissue compared with control animals.

In summary, the results support that there is a possibility of adverse effect from fluoride exposure on the children’s neurodevelopment.  The researchers also encourage future research that would formally evaluate the dose-response relations based on the individual level of exposure over time.  These include assessment on the prenatal exposure and extensive standardized measures on the neurobehavioral performance in addition to control of possible confounders and improving assessment.

Growing Research Studies Have Consistently Linked Fluoride to Brain Damage and Reduce IQ Levels

FLOURIDEThere is growing number of research studies showing the toxic and direct effects of fluoride on the body.  It is indeed interesting to note that despite this claims, it is not even considered as a scientific consensus.  Despite the existing evidence against it, fluoride remains to be added to almost 70% of the public drinking water supplies in the US.

It is in fact unbelievable how the medical and dental communities are so stubborn in connecting and analyzing these findings when in fact there is a growing number of behavioral issues in children and cognitive decline in adults. The authors believed that the behavioral problem in children such as depression, ADD, ADHD and other learning disabilities can be associated with fluoridated water. As a matter of fact, there are over 23 human studies and more than 100 animal studies conducted that link fluoride to brain damage!

Fluoride can also raise the level of manganese absorption which could worsen the problem because the presence of manganese in drinking water can be linked to lower IQ levels in children.

The reported effects of fluoride on the brain include:

  • Accumulation of fluoride in the pineal gland
  • Increased aluminum uptake
  • Impaired defense system of antioxidants
  • Exacerbations of the lesions caused by iodine deficiency
  • Damage to Purkinje cells
  • Reduction in lipid content
  • Formation of the beta-amyloid plaques which is a classic brain abnormality seen in Alzheimer’s disease
  • Damage to the hippocampus
  • Reduction in the receptors of nicotinic acetylcholine

Six Facts that You Need to Know on Fluoridated Water


  1. Did you know that Fluoride is a Drug used for mass medication for the population with no control of dosing?
  2. The two most common types of fluoride present in drinking water are hydrofluorosilisic acid and silicofluoride which are waste products from wet scrubbing systems of fertilizer industry and classified as hazardous waste.
  3. There are more than 23 human studies and over 100 animal studies that are associated fluoride with brain damage.
  4. 50% of the ingested fluoride is directly stored on the children’s bone while 10% is deposited on the adult bones.
  5. According to the evidences of the Centers for Disease Control and Prevention or CDC – 41 % of children in America have dental fluorosis which is caused by excess fluoride.
  6. Almost 99% of fluoride water goes down and drain into the environment.

Harmful Effects of Fluoride have been known for Over 50 Years!

It is surprising to note that the harmful effects of fluoride have been known for over half a century by conventional medical organizations.   Record shows that in the statement issued on September 18, 1943 published in the Journal of American Medical Association or JAMA, researchers said that fluoride are generally protoplasmic poison that can change the permeability of the cell membrane through certain enzymes.

Another editorial issue published on October 1, 1944 in the Journal of American Dental Association stated that drinking water with at least 1.2 ppm fluoride may cause developmental disturbances.  They even recommend stopping it because of its serious systemic disturbances.  They pointed out that the harm outweighs the good.

The problem with fluoride is that it is an accumulative toxin that in time may lead to significant health issues that are not immediately associated with over-exposure to fluoride.  In a 2005 paper entitled Fluoride – A Modern Toxic Waste, Lita Lee, Ph.D. writes that in Yiamouyiannis book entitled Fluoride the Aging Factor, the cumulative effects of tissue damage caused by fluoride was documented. This is commonly seen as gastrointestinal disorders, acne, skin rashes, aging or collagen damage and other conditions such as osteoporosis.   The Safe Water Foundation and the US Center for Disease Control and Prevention reported that almost 30,000 to 50,000 excess deaths have occurred in the United States every year in areas where the water has only one ppm fluoride.

Lee further states that fluoride suppresses the functioning of the immune system.  It also inhibits the white blood cells movement by 70% decreasing their ability to reach the target.  Yiamouyannis even cited 15 references in his pamphlet called Lifesavers Guide to Fluoridation which documents the immunosuppressive effect of at least 10 percent of the amount of fluoride present in fluoridated water.  Immunosuppressive effects runs in a gamut from a cold that just don’t go away to higher risk of cancer and other kinds of infectious diseases.

water-or-fluoride1Research shows that fluoride toxicity can lead to wide-array of health problems including:

  • Increased infertility and damage sperm
  • Disruption of the Immune System
  • Increased cancer and tumor rate
  • Cell death and genetic damage
  • Inhibited formation of antibodies
  • Inhibits more than 100 enzymes and inactivates 62 enzymes
  • Osteosarcoma or bone cancer
  • Reduced thyroid function
  • Bone Fracture
  • Dementia
  • Arthritis
  • Thyroid Disease
  • Muscle Disorder
  • Lethargy or Hyperactivity
  • Disrupt Collagen Synthesis
  • Increased Absorption of Lead

Fluoride Link to Cancer: A Suppress Science

dr dean burk national cancer institute fluorideDr. Dean Burk who worked for 34 years at the National Cancer Institute said a disturbing statement, he quote that, the point of the fact is, fluoride causes more human cancer death and its effect is faster than any other chemical!

This long-lost research establishing a connection with fluoride to cancer has recently resurfaced in a Dutch film clip featuring Dr. Burk.  He cofounded the US National Cancer Institute or NCI in 1937 and headed the cytochemistry department for over 30 years.  In the taped interview, he compared fluoridation to public murder referring to the study that has been done on the 10 of the largest cities in the US with fluoridation compared with the 10 largest cities without.

The study demonstrates that the abrupt rose in cancer death arises a little as a year or two after the fluoridation began.  This and many other studies linking fluoride to cancer were ordered by the government but were hidden quickly once fluoride was found out to be linked to a dramatic increase in cancer.

This disturbing information will hope to shed a light for people to understand the possible effects of fluoride on drinking water and its neurotoxicity.  The authors hope that the public will not be blinded by the false belief and find ways to reveal the truth.
