Hi I’m Wunmi and welcome to Behind the
Headlines, the science behind the news. This week the Mail Online reported that
pregnant women who drink flouride-treated water may have children with lower IQs. Fluoride is a mineral that is known to strengthen tooth enamel and prevent tooth decay. For this reason some areas in the UK add fluoride to their water supply, particularly in the Midlands and in the North. Most toothpaste products and some foods also contain fluoride.

The researchers estimated fluoride exposure during each mother’s pregnancy They then looked at whether this was linked with their child’s IQ once they had reached
3 to 4 old. The researchers found that a 1 milligram increase in
the mothers estimated daily fluoride intake was linked with a 3.7 point lower child IQ score. This link was for boys only with no link
found for girls. The results from Canada and the US could be influenced by many hereditary, lifestyle and environmental factors so they need to be interpreted carefully. This small study can’t prove that fluoride exposure in pregnancy
directly affects a child’s IQ. Considerable past research has been
conducted into the safety of fluoride so pregnant women shouldn’t be concerned
that they need to change their water drinking habits or avoid fluoridated dental
products. If you want to find out more about this story click on the link.
