John Oliver has been great all year with COVID coverage, and this episode also kicks ass.
Is fluoride making us idiots? Was General Jack D. Ripper right after all?
Probably not. Lots of limitations on the most recent study, including long-term vs episodic fluoride exposure, controlling for lead exposure, noisy data, and a couple of individuals with extremely low IQ’s that may have thrown the entire data set. Also, previous studies indicated problems only at extremely high fluoride exposures – much higher than typical water fluoridation.
But don’t let that prevent us from getting a good panic on!
