A student today asked about the fluoridation of water and if it is healthy to drink fluoridated water. I was curious myself so I looked up some information during my lunch break. The Environmental Protection Agency has recommended levels for Fluoride in drinking water. They set the maximum amount as 4mg/L or 4 parts per million (ppm) and in other places where fluoride salts occur more naturally it's even lower 2mg/L (2ppm). After that I searched for some articles that talked about how fluoride hurts the brain. I searched on Google Scholar and found an article entitled, Neuorotoxicity of sodium fluoride in rats. One of the claims from my student was that fluoride affected brain function. This article supports that idea. However, the concentration the rats were exposed to is 75-200 ppm. The difference in concentration is rather drastic.
I will offer extra credit to anyone who can find the concentration of fluoride salts in local drinking water.
