Fluoride Action Network

Excerpt:

The diabetes mortality rate was lower (37.0) for the fluoridated areas than for the unfluoridated (45.2); this difference was statistically significant (P<0.01). Thus, the adjusted mortality rates for all causes and for cerebrovascular diseases and diabetes mellitus all tended to be higher in the unfluoridated areas than in the fluoridated.

… A general pattern was observed in the mortality for all causes and for diabetes; that is, that the lower the level of fluoride, the higher the level of mortality. Specifically, the mortality rates for all causes and for diabetes for communities with less than 0.20 ppm fluoride were significantly higher (P<0.001) than those for communities with 0.50-0.99 ppm or 1.00 or more ppm fluoride. …
