Let’s say dental fluorosis goes down to 20 percent. Is 20 percent an acceptable level of harm? How about 10 percent? Who decides what the acceptable level of collateral damage is?
Remarkably, the Sacramento Bee5 reports that: “Recent unpublished federal research found there’s no regional differences in the amount of water kids drink. So it makes sense for the same levels to be used everywhere, health officials said.”
I’d be very curious to review that study, because I have a hard time imagining that kids everywhere drink the same amount of water!
It’s also a ludicrous assumption unless every single child is also exposed to the same amount of fluoride from other sources besides drinking water… and weighs the same… and has the same health status… and we know that’s simply not the case.
According to the HHS, the Environmental Protection Agency (EPA) “uses the 90th percentile of drinking water intake for all age groups to calculate the relative contribution for each fluoride source.”
