My dad suggested that I read an article in The Coast last month and, slacker that I am, I just got around to reading it. It was written by the founder of “Safe Water Halifax”, an organization opposed to the addition of fluoride to our municipal water supply. Honestly, I find it appalling that an article could be written by a homeopath and student of holistic nutrition, claim to be supportive of science, and yet contain zero links to scientific research. This is not an opinion piece. This is not a personal blog. This is a newspaper article which makes claims regarding the safety of fluoridation yet cites no research to support the claims. The argument? Fluoride is poison and the government has no right to added things to our water.
If fluoride in our water is poisoning us then why is there absolutely no mention in the article of the ailments it’s inflicting upon us? I did blog last year about a report claiming that fluoride in drinking water lowered IQs in children, and was pretty much responsible for every imaginable illness (but wait!… I thought that was wheat…). A statement by the Institute for Science in Medicine provides some background on the history of municipal water fluoridation. It states that at levels between 0.6 and 1.1 ppm there is a wide margin of safety while providing the benefit of increased tooth and bone strength and decreased cavities in children by 20-40%. Only at concentrations greater than 4.0 ppm does it become a risk. And that risk is more cosmetic (i.e. stained teeth) than anything. In Halifax, the average level of fluoride in the water supply is 0.72 ppm. Well within safe limits.
I think that it’s great for people to question the decisions of government and to do research to look out for our own best interests. However, when the crux of your argument is that you distrust anything the government is adding to your food it’s not exactly a solid argument. Without the addition of iron and folic acid to white flour many more people would be suffering from iron-deficiency anemia and many more children would be born with neural tube defects. Iron, like fluoride, is a mineral. Iron, like fluoride (and nearly everything) can be toxic in excessive amounts. Yet, it would be physically impossible to overdose on iron by eating bread. The same can be said for drinking fluoridated tap water. You would die from hyponatremia before you would perish from fluoride toxicity. The fortification of flour with folic acid has been the most effective measure in reducing neural tube defects, such as spina bifida. The addition of iodine to table salt reduced the incidence of goiters and mental deficiency significantly in North America. However, iodine deficiency is becoming a public health concern again as we increasingly use un-iodized salts such as sea salt and rely on un-fortified processed foods. I could go on and on… What about vitamin D added to milk? Calcium and vitamin D enriched milk alternatives?
My point is that the addition of vitamins and minerals to foods and beverages is done to benefit the population. There is no more reason to fear the fluoride in our water than there is to fear all of the other examples above.
