"I worry about it tremendously. We're forever incorporating Nazi things into our lives. Fluoride in the water, that was originally done by the Nazis! I don't particularly like anything the Nazis did too much, and they were the first ones to put fluoride in the water. They tell us, 'Oh, it's for your teeth' and all that - well, isn't that your parents' job, to teach you how to brush your teeth and use mouthwash? Why do you need the government putting some type of chemical in your water? I don't know if you know this [but] fluoride is the main component of Prozac! What you've got is people drinking Prozac-water. Well, what does Prozac do to you? It calms you and dumbs you down so you're less emotional. There's a reason for all that stuff; what do we need fluoride in our water for? There's no reason whatsoever to put chemicals in our water."

Ventura's answer offers us a lot to analyze, but one of his claims -- that "fluoride in the water ... was originally done by the Nazis" -- stood out out to us because PolitiFact Florida debunked this precise claim in 2011.

Nazis, who killed millions of Jews in the 1930s and 1940s, were known for chemical tests and inhumane medical experiments. Far be it from us to defend them, even in a minor way.

But after tracking down the roots of claims about fluoride on the Web, reaching out to Holocaust historians, contacting well-known critics of water fluoridation, and reading book excerpts, magazine articles, and news stories, we concluded that there's no teeth to this claim.
