A U.S. government report expected to stir debate concluded that fluoride in drinking water at twice the recommended limit is linked with lower IQ in children.

The report, based on an analysis of previously published research, marks the first time a federal agency has determined — “with moderate confidence” — that there is a link between higher levels of fluoride exposure and lower IQ in kids. While the report was not designed to evaluate the health effects of fluoride in drinking water alone, it is a striking acknowledgment of a potential neurological risk from high levels of fluoride.

Fluoride strengthens teeth and reduces cavities by replacing minerals lost during normal wear and tear, according to the U.S. Centers for Disease Control and Prevention. The addition of low levels of fluoride to drinking water has long been considered one of the greatest public health achievements of the last century.

“I think this (report) is crucial in our understanding” of this risk, said Ashley Malin, a University of Florida researcher who has studied the affect of higher fluoride levels in pregnant women on their children. She called it the most rigorously conducted report of its kind.

    I once had an argument over someone who was anti fluoride. They said it makes you dumb. But they have also in the past commented that I was smart, so I said imagine how smart I’d be without fluoride? They don’t have a comeback for that one.

    Also too much oxygen (twice the limit) will also cause you harm and possibly kill you, do we ban oxygen?

      My son’s currently in the NICU. He recently came off his breathing tube, after receiving a DART steroid treatment to encourage proper lung development. Up until this point, he needed 30-40% oxygen (normal earth atmosphere has 21% oxygen) to survive. After the treatment, he was able to breath on a bubble-CPAP, which put significantly less strain on his lungs and reduced his oxygen requirement down into the mid-20s.

      Back in the 90s, the DART steroid treatment was considered a fantastic pharmaceutical innovation precisely because it encouraged this rapid recovery. However, long term testing of infants on the treatment revealed a high risk of cerebral palsy. This was much worse than the damage inflicted on the lungs due to prolonged ventilator treatment, and so use of DART was halted. But fairly recently (the last decade or so) a minimal treatment of DART was experimented with on children with sever breathing problems. The lower dosage over a shorter delivery window yielded much the same results as the original study (rapid lung development) without the mental health impact. Kids came off the vent sooner (which meant less lung damage from the vent pressure and high oxygen) while experiencing minimal side effects. Now DART is the standard for premature babies with difficulty breathing on their own.

      This is hardly the first time a medication has experienced such a historical arc. But the hysterics around industrial medicine, combined with the rather shitty history of experimental medical studies (Tuskegee Experiments, St. Louis slums radiation experimentation, Phen Phen and Oxycotin scandals, Theranos) and a fixation on “naturalism” as a panacea, do lead people to weird places.

      I can understand why people are terrified of fluorine in their drinking water, given how much lead ends up in there, too. But I do think the fixation on one serves to inhibit discussion of the other. Curious how guys like Alex Jones and Joe Rogan will peddle these conspiracies ad nauseum while staying well clear of the far more profitable toxic waste that ends up harming enormous swaths of the American lower classes.
