Study Finds Fluoride Affects IQ Of Children

Fluoride in water reduces IQ
A study released by the National Institute of Environment Health Sciences (NIH) says that high concentration of fluoride in drinking water can cause adverse effects of a child's neuro development.

The study, titled Developmental Fluoride Neurotoxicity: A Systematic Review and Meta-Analysis" by Choi, Sun, Zhang, and Grandjean revealed a difference in IQ scores between children who lived in high exposure fluoride areas as opposed those who didn't.

To arrive at their conclusions, the group poured through databases from Embase, MEDLINE, , water resource abstracts, and the China National Knowledge Infrastructure database.

For decades, water fluoridation has been a controversy with many countries banning the practice.

In the United States, fluoride is commonly found in toothpaste and also added to municipal drinking water to promote dental health. The Environmental Protection Agency (EPA) oversees the laws set for drinking water under the Safe Drinking Water Act of 1974. In Europe and Asia, they do not practice water fluoridation in drinking water. Many countries stopped this practice in 1970 and 1990 as they found no evidence of its purported benefits.

If you are concerned about fluoride in your drinking water consider the following:

  • Reverse osmosis water filter systems
  • Fluoride filters

For those who want to avoid it in their toothpaste, there are fluoride free products available from Tom's of Maine and Burt's Bees.
