Researchers Hid Data Showing Fluoride Lowers Kids’ IQs, Emails Reveal

A team of pro-fluoride researchers led by California’s dental director intentionally omitted data from a study seeking to undermine the forthcoming National Toxicology Program (NTP) report linking fluoride exposure to neurodevelopmental damage in children, according to documents released last week.The documents — obtained through a California public records search and posted in a press release by the Fluoride Action Network — show that the team, led by Dr. Jayanth V. Kumar, a dental surgeon, conducted a meta-analysis of the scientific literature on fluoride’s neurotoxicity and found a link between fluoride exposure and lowered IQ in children at low levels of exposure.

However, they omitted the data and wrote a paper concluding there was no evidence of a link.
