New Study Claims Excessive Exposure of Fluoride in Pregnancy Affects IQ Levels of Children

The US CDC has praised adding fluoride to common water sources as a safe and efficient way to boost public health. Before this, many studies have revealed the beneficial effects of fluoride. For the past seven decades, fluoridated-water has helped Americans resulting in better dental health. But a new clinical trial gives rise to questions regarding fluorides role as a possible neurotoxin in the uterus.

A study claims exposure to high levels of fluoride to a baby in womb results in children with low IQ. Scientists from Canada’s York University, Toronto, have carried out the study. Even more, they have published the results in the Journal JAMA Pediatrics on Monday. The research focuses on estimating the impact of fluoride on public health. It also questions the US Public Health Service’s decision, which permits 0.7 mg of fluoride in 1 liter of drinking water. The negative impact of an element which protects teeth from decay has puzzled an associate professor of psychology at the York University Christine Till. She says it is essential that judgments regarding safety rely on some evidence. Thus the professor and team decided to conduct a study.

During the trial, they have studied more than 500 Canadian women along with their babies. The scientists have assessed fluoride consumption and their children’s IQ scores. To measure fluoride exposure in pregnant women, they opted to test urine samples. The team has also considered the amount of fluoride in a city’s water source. They have discovered for every 1mg per liter rise in fluoride consumption by a mother has resulted in a massive fall in the baby’s IQ. As per Christine, the leading author of the study, after looking at the urinary fluoride, they thought it had affected only boys. After analyzing other aspects, the team found that fluoride exposure had affected both type of fetus, i.e., girls and boys. Still, the study requires further research to pinpoint the negative impact of fluoride on pregnant women.
