Forensic Toxicologist Finds Fluoride Toxic to Neurons
1988. Dr. Phyllis J. Mullenix is asked to test fluoride toxicity in rats by her new employers, the Forsyth Dental Research Institute. She assumed that her results would be negative - but to her astonishment, she found a positive correlation between blood levels of fluoride and neuronal toxicity: in lay terms, fluoride was able to get into the brain of rats at blood levels similar to those found in humans. The paper was published in 1994: Neurotoxicity of sodium fluoride in rats. The following video is of poor quality: bad sound, bad lighting, but it shows that Dr. Mullenix is a serious researcher.
