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 learned all of that myself decades ago at Uni. I had a high level water class and we were supposed to do a one-hour presentation on a topic of our choice.

        During my research to come up with a topic for the lecture I read an article about a small town in Canada that ran out of fluoride for their water supply. The article cited a downturn in fertilizer production as the culprit.

        I was very confused at first. Going to the EPA website revealed that fluoride was a naturally occuring compound in water supplies. No mention of how you could run out of something naturally occuring in water.

        I went on a trip with the class to a water plant. I asked the operator there about fluoride. He explained they added it to the water and it was not naturally occuring.

        This lead me to discover that fertilizer plants sold their toxic waste product to municipalities instead of disposing of it properly. Mind blown. Furthermore the research proving fluoride in the water supplies prevented cavities was flawed at best.

        My research indicated that fluoride causes a developmental delay which results in teeth eruption about two years later than normal. So fluoride poisoning makes it look like your teenage teeth have fewer cavities but they are just not as old.

        Once you looked at these same teeth later on there was no real difference. So the benefit of having your teeth erupt later disappeared as you got older. Which makes a lot of sense.

        There is no clinical reason to ingest pharmaceutical grade fluoride let alone the toxic shit that comes from the scrubbers of fertilizer plants. There is no mechanism to return fluoride to your teeth except maybe throwing up before it has been absorbed.

        My presentation went great. Everyone was fascinated and I got a near perfect score. I am not a fluoride hater because fluoride works great topically.

        The truth is astounding and the amount of pushback I have gotten explaining all this on the Internet has been ridiculous to say the least.

          what i find baffling is the fervent insistence that it be added to the water supply that can’t be avoided. as if the whole universe is going to implode if they take away our precious fluoride in the water
