“We measure risk from total exposure not from one isolated source.” - Bruce Lanphear

Brain researcher Bruce Lanphear is interviewed by Vox's Laura Bult on fluoride's effect on the brain and the recent NTP meta analysis on fluoride neurotoxicity.

“The meta analysis is really a way to synthesize and quantify the high quality studies and the low quality studies and try to make sense of it. Because otherwise what you’re left with is: these studies, which are my favorite studies, said this and that confirms my belief, and these studies, which did that, don’t confirm my belief and clearly they’re wrong.”
