Fluoride Reduces IQ of children

Fluoride Reduces IQ of children

A new study provides strong evidence that fluoride reduces IQ in children. The study was pre-published in Environmental Health Perspectives[1], a publication of the National Institute of Environmental Health Sciences (online December 17, 2010).

"The 25 NZ local body councils [2] (out of a total of 69) that still add fluoride to drinking water must take heed. It is now likely that fluoridation is reducing the IQ of children in this country" says Mary Byrne, spokesperson for Fluoride Action Network New Zealand. "I'm sure most parents in NZ, knowing this information, would agree that this is outrageous and unacceptable."

According to Paul Connett, Ph.D., director of the Fluoride Action Network, "This is the 24th study that has found this association, but this study is stronger than the rest because the authors have controlled for key confounding variables and in addition to correlating lowered IQ with levels of fluoride in the water, the authors found a correlation between lowered IQ and fluoride levels in children's blood. This brings us closer to a cause and effect relationship between fluoride exposure and brain damage in children."

In this study, 512 children aged 8-13 years in two Chinese villages were studied and tested - Wamaio with an average of 2.47 mg/L water fluoride and Xinhuai averaging 0.36 mg/L.

The authors eliminated other possible causes such as lead exposure and iodine deficiency, and children with a history of brain disease or head injury. None drank brick tea, known to contain high fluoride levels. Neither village is exposed to fluoride pollution from burning coal or other industrial sources.

About 28% of the children in the low-fluoride area scored as bright, normal or higher intelligence compared to only 8% in the "high" fluoride area of Wamaio. In the high-fluoride area, 15% had scores indicating mental retardation and only 6% in the low-fluoride area.

The study authors write: "In this study we found a significant dose-response relation between fluoride level in serum and children's IQ."

There have also been over 100 animal studies linking fluoride to brain damage.

"In New Zealand, either Sodium Fluorosilicate [4] or Hydrofluorosilicic Acid [5] (both classified as Hazardous Waste according to their MSDS) is added to water to 0.7 mg/L - 1 mg/L. This is very close to the levels in the "high-fluoride" area and the chemical fluorides added to New Zealand are far more toxic than naturally occurring calcium fluoride found in the Chinese villages" say Ms Byrne.
