I read some studies about various Chinese villages that were subjected to varying levels of Flouride. Those villages with higher flouride levels had a significantly higher level of mental retardation.
Why do babies need flouride, they dont even have teeth.
If you really want some healthy water, try some that hasn't been treated by chlorine. I read another study that said that people who drink more than 8 glasses of tap water a day are at an increased risk for bladder cancer because of the chloramines (chlorine compound) in tap water.
As for me, all I drink is coffee.
