Let’s start with the 2006 NRC Report. According to the authors:
“On the basis of information largely derived from histological, chemical, and molecular studies, it is apparent that fluorides have the ability to interfere with the functions of the brain and the body by direct and indirect means” .
The Fluoride Action Network has produced a very useful database for all the relevant information on this topic. We suggest taking a look .
Basically, it all comes down to ‘margin of safety’ . Mullenix also gives an interesting biochemical overview, for those interested in learning more .
