Fluoride Can Reduce IQ in Children
A group of researchers reviewed studies from around the world in order to determine if fluoride (usually from fluoridated drinking water) may cause neurotoxicity in children. Their study went on examine the potential impact that fluoride may have on children’s IQ scores.
After careful analysis, the researchers were able to measure a significant difference between children who had been exposed to higher levels of fluoride and those who had not. They found that “children in high-fluoride areas had significantly lower IQ scores than those who lived in low-fluoride areas.”
This is obviously a major concern as much of the drinking water in the United States contains some level of fluoride. The Researchers concluded that “the results support the possibility of an adverse effect of high fluoride exposure on children’s neurodevelopment. Future research should include detailed individual-level information on prenatal exposure, neurobehavioral performance, and covariates for adjustment.”
The EPA requires fluoride levels to be no more than 4.0 mg/L or 4.0 ppm, with a recommended level of 2.0 mg/L or 2.0 ppm. IN January 2011, the U.S. Department of Health and Human Services and Environmental Protection Agency recommended that these levels be reduced to 0.7 mg/L or 0.7 ppm. Concerned parents would be wise to contact their water company and ask for a report showing the amount of fluoride in their drinking water and consider supplementing with bottled water if they believe it is too high.
