there is evidence that regular floride ingestion inhibits iodide uptake reducing thyroid hormone production reducing metabolic rate, affects G-protein pathways reducing both insulin insensitivity, and secretion. in other words, it makes you stupid and fat.
also learned the reason it is in the water is so the chemical fertilizer industry can sell their production waste as a water additive rather than have to pay to dispose of toxic chems.
