Researchers focused on the intelligent development that is diminished by high levels of fluoride in drinking water, Infowars reported. The study, which was performed on rats for a period of 60 days, showed that fluoride caused neurodegenerative and morphological alterations in the neocortex, hippocampus and cerebellum areas of the brain, and in the spinal cord and sciatic nerve.
“High levels of fluoride in drinking water (1-12 ppm) affect central nervous system directly without first causing the physical deformities of skeletal fluorosis,” K. Pratap Reddy of the University College of sciences at Osmania University in Hyderabad wrote in the Journal of Medical and Allied Sciences.
According to the Fluoride Action Network (FAN), there are now 25 studies showing that fluoride is associated with IQ reduction, even at fluoride levels as low as 0.3 to 3 parts per million, which overlaps the range in many American communities (0.7 to 1.2 ppm).
A previous rat study conducted by Dr. Phyllis Mullenix and her colleagues in 1995 showed that fluoride “can be indicative of a potential for motor dysfunction, IQ deficits and/or learning disabilities in humans.”
Numerous studies conducted in different countries such as the US, Mexico, China and India have determined that fluoride exposure is associated with IQ deficits in children. Source
