New Study Proves Children Exposed to High Levels of Fluoride Have Reduced Intelligence

New Study Proves Children Exposed to High Levels of Fluoride Have Reduced Intelligence Written by Andrew Puhanic

A new study published in the Journal of Neurosciences in Rural Practice titled ‘Effect of fluoride exposure on the intelligence of school children in Madhya Pradesh India’ has discovered that there is a significant relationship between intelligence in children and the level of fluoride in water.

The study was conducted in the Madhya Pradesh state of India using a cross-section of 12-year-old school children.

Children that were selected for the study were from areas that contained low levels of fluoride in their drinking water (Less than 1.5 parts per million) and high levels of fluoride in their drinking water (Greater than 1.5 parts per million).

The researchers concluded that average test scores between children who were exposed to high levels of fluoridated water had a statistically significant lower level of intelligence as compared to those children who were exposed to low levels of fluoride.

The Children’s intelligence was measured using the Raven’s Standard Progressive Matrices. As can be observed from the graph below, there is a significant cancellation between the water fluoride levels and intelligence.

intelligence grades of children with different levels of wat fluoride

The lowest mean grade was observed with water fluoride level <1.5 PPM. The highest mean grade (worst intelligence) was observed with water fluoride level >4.5 PPM. The differences for intelligence grades were statistically significant between the four groups.

Other recent studies into the effects of fluoride on the intelligence of children also concur with the study published in the Journal of Neurosciences in Rural Practice:

  • Researchers from the Harvard School of Public Health (HSPH) and the China Medical University (CMU) analysed the results of over 20 studies and also concluded that children who are exposed to high levels of fluoride may have their cognitive development impaired.
  • In another study recently published in Environmental Health Perspectives, Over 500 children from two villages in China who were exposed to both low and high levels of fluoride were analysed. The study concluded that there was a significant relation between fluoride levels and children’s IQ.
  • A review of 11 studies involving more than 7,000 children showed that the effect of fluoride supplements on primary teeth could not be determined, with one study showing no cavity-reducing effect

Data from this research supports that children exposed to fluoride are at risk of impaired development of intelligence. Millions of children around the world are exposed to high concentration of fluoride in water, and are therefore, potentially at risk.

For the benefit of the upcoming generations, urgent attention needs to be focused on this substantial public health problem.

    According to http://en.wikipedia.org/wiki/Water_fluoridation :

    “The U.S. specifies the optimal level of fluoride to range from 0.7 to 1.2 mg/L (milligrams per liter, equivalent to parts per million)”

      You can not control the doses people receive in their water because some drink more than others. People should not be drinking sodium fluoride. If you want fluoride for your teeth use a toothpaste with it. Toothpaste still has the warning on it not to ingest it. Also the “fluoride” put in our water is not just sodium fluoride from industrial waste but a cocktail of other industrial waste byproducts.

      I forgot to mention it even comes to your water plant (and stored at the water plant)in a container with skull and crossbones on it.

    correlation is not causation, I really wish you guys would filter this crap out before you post it thinking you’re onto “the man”

    without flouridation of water, your teeth would be rotting much faster, which is better, good teeth or slightly lowered intelligence.

    I’ve been drinking flouridated water for 34 years and I’m a pretty dammed clever guy (a-thankyou!) so if I can drink it and still be intelligent, then if you find some sort of correlation between the two, perhaps the people involved in the study just aren’t very intelligent in the first place….

      which is better, good teeth or slightly lowered intelligence. – ridiculous question, no question mark.

      I’ve been drinking flouridated water for 34 years and I’m a pretty dammed clever guy (a-thankyou!) – grammatically and factually incorrect.

      so if I can drink it and still be intelligent, then if you find some sort of correlation between the two, perhaps the people involved in the study just aren’t very intelligent in the first place…. – If an intelligent person has a slightly lowered IQ they will still be intelligent, doesn’t change the fact that the intelligence was lowered.

      Drink the Kool-Aid.

      “without flouridation of water, your teeth would be rotting much faster, which is better, good teeth or slightly lowered intelligence.”
      That is not necessarily the case. One can supplement fluoride in ways other than, in drinking water. Someone isn’t necessarily going to have worse teeth because they don’t use fluoridated water. There are other ways to get it. The amount of fluoride is important too. Too much fluoride actually damages teeth and bones (skeletal fluorosis), not to mention, causes death.
      It is a poison. It’s known to be neurotoxic to adults. So logically, the higher the amount in drinking water, the lower IQ people will have.
      Here’s an excerpt from a Harvard website:
      “Extremely high levels of fluoride are known to cause neurotoxicity in adults, and negative impacts on memory and learning have been reported in rodent studies”
      and the site the excerpt is from:

      and a link on skeletal fluorosis:

    If your so damn intelligent maybe you should reduce your sugar frequency intake and improve your oral hygiene therefore iliminating your susceptability to dental caries..and as a smart guy you should realise sunstances effect individuals in different ways
