Ha! Well, I don't know how informative my post was since it had no references and was at least 20% bitching about paranoid anti-government types, but thanks! Problem is that while there are plenty of small studies on the subject, as far as I'm aware, none have been consolidated into a large controlled trial... specifically some form of blind trial as the topic is fairly prone to controversy.
A lot of the smaller studies have been really prone to shitty methodology and poor conclusions, as well... sort of like the one that claims the calcification of the pineal gland due to fluoride is responsible for the increasingly early onset of puberty for girls... ignoring that that statistic has been going down since the mid 19th century, for both sexes. I guess Charles Darwin was poisoning the water supply in all Western countries, or something, ha.
Sorry about the rambling dude! It's just a topic that sets me off, a lot like the vaccination "controversy", ugh.
