NEW IQ STUDY - Includes total fluoride dose in both food and water, etc.

Fluoride Action Network (FAN)

Another Chinese IQ study published

FAN has recently obtained the summary of a new Chinese study linking fluoride exposure to reduced intelligence in children. Incredibly, this is the 36th study to find an association between fluoride and reduced intelligence. Although FAN has yet to translate the full study, a translation of the abstract reveals that the scientists not only examined the neurological impact of fluoride in water, but also the neurological impact of the total fluoride dose from all sources. According to the summary, the children in the high-fluoride community (0.57 to 4.5 ppm) had an average of 8 less IQ points than children from the lower fluoride community (0.18 to 0.76 ppm). When the authors controlled for other sources of fluoride in the children's diets, they found a significant "dose response" trend, meaning that children with higher total daily intakes of fluoride tended to have lower IQs than children with low fluoride intakes. The total daily doses ranged from 1 mg/day to 4+ mg/day -- a dose range that overlaps the doses that millions of American children now regularly receive.

FAN obtained this study as part of our ongoing translation project where we monitor, access, and translate critical studies from China and Russia that would otherwise never see the light of day in the U.S. As Michael Connett explains below, FAN's translation project has already had a significant impact on the scientific debate, and we expect this impact will continue to increase in the months ahead.
