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.
You can do a whole house RO system if you really care, but you need to be mindful that it can have serious downsides if the RO water sits in the pipes for too long while you are away from your house (Bad bacteria).
RO removes everything- the minerals that help your mouth healthy, the chlorine or chloramine inhibiting bacterial growth in your pipes, heavy metals and microplastics and PFAS that could be in the water (though this is null and void if your housepipes are plastic or lead or treated with PFAS)
…generally, unless you are living with extremely dangerous water, or you have massive aquariums that need more than a kiddie pool of water a week, you don’t need RO systems.
