A new study suggests that prenatal exposure to this chemical may affect cognitive abilities and that children born to mothers exposed to high amounts of fluoride could have lower IQs.
Tap water contains flouride and that is the issue. What the study is actually saying in summary is that as a pregnant mother fluoride is bad for your child.
The study, published Tuesday in Environmental Health Perspectives, found an association between lower intelligence and prenatal fluoride exposure in 299 mother-child pairs in Mexico.
Even when other possible factors were taken into account, such as exposure to other chemicals, results continually showed that higher prenatal fluoride exposure was linked to lower scores on tests of cognitive function in children at age 4 and then again between 6 and 12.
“This is a very well-conducted study, and it raises serious concerns about fluoride supplementation in water,” says Dr. Leonardo Trasande, a pediatrician who studies potential links between environmental exposures and health problems at New York University Langone Health. (He was not involved in the new study.)
“These new insights raise concerns that the prenatal period may be highly vulnerable and may require additional reconsideration,” Trasande says.
