Harvard Study Concludes that Fluoridated Water Is Associated with Lower IQs in Children
Tuesday, August 07, 2012
Researchers at Harvard and in China have concluded that fluoride in water may impair children’s mental development.
After examining the results of 27 Chinese-based studies, experts from the Harvard School of Public Health and China Medical University in Shenyang found evidence that fluoride may adversely affect cognitive development in children.
They determined children in areas of high-fluoride concentration areas had noticeably lower IQ scores than those who lived in low-fluoride areas. Even though the average IQ measurement was only half a point less, some studies showed that even small exposures to fluoride could be toxic to the brain, the researchers said.
They added the potential risks of fluoride exposure should be taken seriously and that more research should be conducted in this area.
