Decades ago there were very strong campaigns against the fluoridation of drinking water supplies, on grounds that doing so would result in innumerable health impacts. As it turned out those fears were unfounded, but — rather ironically—the science is in on tooth decay and nutrition. Modern Western diets not only cause the rotting of our teeth, it has caused immense health problems resulting in the deaths and debilitation of millions.
Our teeth were like the proverbial canary-in-the-coal-mine and we should have learned way back then to move away from sugars and processed carbohydrates. Instead we tried to paper over those early warnings by putting fluoride in water supplies.
In a round about sort of way fluoridation was the wrong response to the dental health problem, but not for the reasons that the anti-fluoridation campaigners had made out. Is there a lesson to be learned from that saga?
