“I would not drink water from a tap, from a sink, because of fluoride. There's lots of evidence that fluoride in excess is harmful for humans. Increased amounts of fluoride in the human diet have been associated with decreased IQ in kids.”
“I would obviously never use fluoride in my toothpaste. I don't think humans need any more fluoride. Higher amounts of fluoride have been consistently correlated with lower IQ in kids. That came out recently.”
