Fluoride In Drinking Water Does Not Cause IQ Loss, US Study Shows
The first long-term study in the U.S. shows that drinking fluoridated water has no negative effect on cognition up to the age of 80. The use of fluoridated water has been shown to reduce tooth decay by 25%. Two states have banned the mineral, while several others have similar legislation pending.
Tests of intelligence and brain function showed the same results whether or not people drank fluoridated water growing up, a highly anticipated, long-term study found. The new research, published Monday in the respected Proceedings of the National Academy of Sciences, is the first to measure community water fluoridation exposure during childhood in the U.S. and any potential impact on cognition up to age 80. The results contradict claims made by Health Secretary Robert F. Kennedy Jr. that fluoride is 鈥渋ndustrial waste鈥 associated with IQ loss. (Edwards and Ozcan, 4/13)
