Is Fluoride Dangerous For Cognitive Development In Children?
Fluoride in drinking water is a constant hot topic among health experts for years. They disagree on the topic of its toxicity, regarding its effect on a human’s brain, especially when it comes to children.
It has been proven that a very high fluoride levels can cause neurotoxic among adults and have serious consequences on learning abilities and memory in rodent studies. Unfortunately, not much is known regarding the effects this substance has on children and their brain development, which makes the correlation between fluoride and children a topic well worth researching.
Some research had been made by the Harvard School of Public Health in cooperation with China Medical University located in Shenyang in which they combined as much as 27 different studies which gave some serious indications that fluoride could possibly have a negative effect on cognitive development among the youngest population. These results proved that more research regarding fluoride and children are warranted.
A thorough review of the studies, which were mostly originating from China where fluoride related risks are well known, had been conducted by the researchers. U.S. however, remain with no human studies regarding the dangers of fluoride and children which is a concerning fact according to Philippe Granjean, a research scientists at HSPH.
There is more evidence suggesting that a correlation between fluoride and children deserves a closer look, even at normal exposure levels similar to those in drinking water. A study had been conducted in 2003 in China, where 222 children were drinking water saturated with a level that is 2.5 times higher than recommended and 290 children consumed water which was fluoridated to a very low level. All of the children involved in the study were of similar backgrounds and ages.
The results showed that the children drinking water with a high level of fluoride had an IQ average of 92, while the other group of children who drank the water with lowfluoride levels had an IQ average of 100. What was most shocking was the fact that there was a much greater number of mentally disabled children in the village where water was highly saturated with fluoride, worrying the scientists running these studies and motivating them to further continue with the exploration of this topic.
While no conclusive results can be made at this time, some of the studies mentioned above highlight the necessity of more thorough and in-depth research regarding the impact fluoride has on brain and learning abilities in children.
