Recent studies have shown that the higher the concentration of fluoride detected in urine, the lower the intelligence of children.
Fluoride is generally known to help prevent tooth decay and is added to drinking water.
However, the researchers investigated the effects of fluoride on 287 pregnant women, and the results were associated with lowering children's intelligence as the concentration of fluoride in the maternal body was higher.
The study was conducted from 1994 to 2005, and the children who measured the IQ ranged from 6 to 12 years old.
The intelligence of children's language skills and memory was tested in two stages. There was no correlation between fluoride detection and intelligence in children, but fluoride detection in pregnant women and children's IQ were statistically related.
Howard Hugh, director of research, stressed that "the growing nervous system of the fetus is very sensitive, so we need to be careful to maintain a healthy environment."
