Exposure To Fluoride Lowers Intelligence
Exposure To Fluoride Lowers Intelligence
Date: 18/03/09
A number of studies have shown that exposure to fluoride can cause behavioural changes. At a 1998 conference on fluoride in Washington, Professor Roger Masters reported a significant link between the blood lead levels of 280 000 children in Massachusetts and the use of silicofluorides (the fluoride added to our water supply – waste products of the fertiliser and glass industries).
In the previous alert, ‘Fluoride in drinking water should be banned’, I touched on some of the detrimental health effects fluoride can have on our health. This is an issue that clearly has many people up in arms. So much so that my colleague, Rachel Linkie writes about it in the April issue of Health Sciences Institute and right you are, we all should be up in arms! More so, we should make as much noise against fluoride in drinking water as we can...
Let the children play or pay?
A number of studies have shown that exposure to fluoride can cause behavioural changes.

Fluoride increases the toxic effects and absorption of lead. Both in the UK and in the American state of Georgia, behavioural changes associated with lead toxicity, such as violent crimes, are more frequently reported in communities using silicofluorides than in areas not using it.
At the same conference in 1998, neurotoxicologist Dr. Phyllis Mullinix, from the Boston Children’s Hospital in Massachusetts reported on the results of a study using two steroids to treat childhood leukaemia. One of the steroids had a fluoride atom in its structure, and the use of this steroid caused behavioural patterns typical of hyperactivity.
A follow-up study also showed a significant drop in the average IQ scores of the children given the steroid with fluoride, compared with those taking the non-fluoride steroid.
Detrimental or just mental?
New studies from China shows that an excessive intake of fluoride can build-up in the brain and permanently reduce the IQ of children.
Two very similar suburban villages in the Shanxi province in China have only one major difference: the level of calcium fluoride in their water supply.
Xinghau’s water contains 0.91 part per million (ppm) of fluoride and 14 per cent of the population has dental fluorosis – mottling, softening, porosity and brittleness of the tooth. They have no cases of skeletal fluorosis.
In contrast, the neighbouring village, Sima, has 4.12 ppm fluoride in its water. 86 per cent of the population shows clear evidence of dental fluorosis and 9 per cent has clinically diagnosed skeletal fluorosis.
In each village, 160 randomly selected children (excluding those with congenital or acquired disease not related to fluoride) took a standard IQ test lasting 40 minutes. Each child’s mother lived in one of the villages during pregnancy. The two studies came to extraordinary and identical conclusions: exposure to high fluoride lowers intelligence, as measured by IQ scores.
The general IQ level score in Sima (high fluoridated water) was 97.7, whereas in Xingua (lower fluoridated water) the general IQ level score was 105.2. That is a 7.5 point or 7.7 per cent difference, which is a significant difference on a statistical level.
Among the 160 children selected for the study, the number of those from Sima with IQs of 69 and lower was sic times that of the children from Xinghua and 26 per cent fewer children in Sima had IQ scores of 120 or above.
These are just two studies in a long list of studies that have been conducted world wide, which all shows time and time again that fluoride holds very little (if any) health benefits.
