I have been filtering water for years and made a decision more than a decade ago that fluoride was not good and left it at that and not looked into the issue since. In Australia, it is up to the local councils to decide whether or not to fluoridate their town water. Some, especially in Queensland have opted not to.
Relooking at this issue in response to a recent request from a client provided a more than severe wake-up call. There is no need for this article to speak volumes about the health dangers of fluoridation because accurate, clear and evidence-based resources are shown below to help you get informed.
“In OUR DAILY DOSE, filmmaker Jeremy Seifert lays out the dangers of water fluoridation informatively and creatively, highlighting the most current research and interviewing top-tier doctors, activists, and attorneys close to the issue.”
Way back in 2006 the Committee on Fluoride in Drinking Water as part of the National Research Council in America published a 530-page report called – Fluoride in Drinking Water: A Scientific Review of EPA’s Standards. (freely available)
Apparently aimed at government policymakers and the EPA, the report identified many potential and already known health problems with the current en-masse fluoridation of the nation’s drinking water. Many health concerns are raised. Off course since that report in 2006, volumes of data have accumulated – mostly incriminating.
Thyroid related highlights (courtesy of the Fluoride Action Network) of the Fluoride in Drinking Water report mentioned above –
- Several lines of information indicate an effect of fluoride exposure on thyroid function
- It ‘s hard to predict what exactly effects on thyroid function are likely at what concentration of fluoride exposure and under what circumstances
- Fluoride exposure in humans is associated with elevated TSH concentrations, increased goiter prevalence, and altered T4 and T3 concentrations; similar effects on T4 and T3 are reported in experimental animals
- In humans, effects on thyroid function were associated with fluoride exposures of 0.05-0.13 mg/kg/day when iodine intake was adequate and 0.01-0.03 mg/kg/day when iodine intake was inadequate
- The recent decline in iodine intake in the United States could contribute to increased toxicity of fluoride for some individuals
- Intake of nutrients such as calcium and iodine often is not reported in studies of fluoride effects. The effects of fluoride on thyroid function, for instance, might depend on whether iodine intake is low, adequate, or high, or whether dietary selenium is adequate
The only reason fluoride is added to drinking water is to help prevent tooth decay in children. However and perhaps the most damning evidence as to the usefulness of fluoridation is the graph shown here from a 2007 study published in the British Journal of Medicine (Adding fluoride to water supplies, BMJ 2007; 335). It demonstrates that tooth decay has declined in many countries, irrespective of whether they fluoridate or not.
