Israel Bans Fluoride, page-20

Oh, for goodness sake. Pass it by the straightforward sniff test. Fluoride (F-), just like chloride (Cl-), occurs naturally in fresh water all over the world, at concentrations from roughly 0.01-10 mg/L. It's also present in seawater at 1-1.5 mg/L. The same seawater our distant fishy ancestors evolved swimming around in; the same fresh water all of our more recent ancestors drank. Do you *really* think we evolved in such a way that the very water we drink would be toxic to us?
