The Truth about Fluoride

Fluoride: Is too much of a good thing a bad thing?

I'm willing to bet you brushed your teeth this morning. You probably use a brand of toothpaste that promises more fluoride for cavity-fighting power. That's a good thing, right? Think again. Scientists have been reconsidering the impact of fluoride for awhile now, and it seems that the government can't ignore the impact of their findings any longer.

Unfortunately, toothpaste isn't all you need to concern yourself with. You see, the government is putting it in the water. Furthermore, most affordable water purifiers don't remove it. Bottled water sometimes provides a viable alternative to drinking tap water, but it can't eliminate fluoride intake completely. The vast majority of consumables are made using fluoridated water obtained from the public supply. If our standards don't change, the problems surrounding fluoride will only become more pronounced as long-term ingestion leads to dire consequences. I've highlighted some of these below. You'll also find a break-down of some of the most popular bottled waters and their fluoride content. Information is provided on different purification methods and their efficiency at removing fluoride. I also remark on some notable victories. Finally, I provide links to sites specializing in the sale of fluoride-free toothpaste.  I urge you to investigate the links toward the bottom of the page for more information, or click on the WorldCat link below to access library resources on the topic. If you do nothing else, sign the e-petition asking for the removal of fluoride from the water supply.


Here's what you need to know:

  •  According to a report published by Peter Mansfield in the latest e-journal of the International Society for Fluoride Research, nearly a quarter of the population of the U.K intakes too much fluoride. To arrive at this conclusion, 2000-2003 intake data from the U.K National Diet and Nutrition Survey was examined. A portion of the recent study concentrated on the amount of fluoride that is absorbed and retained. As it turns out, the absorption and retention rate is variable. Children below the age of 7 absorb and retain more fluoride, which potentially puts them at greater risk. 
  • Some studies suggest that fluoride impairs brain function, specifically targeting that portion of the brain that controls memory and learning. For instance, Chunxiang Wu pioneered a study in 2006 that evaluated the effects of high doses of fluoride and arsenic on lab rats. Another Chinese study found that children who routinely drank well water that contained a higher than normal concentration of fluoride performed poorly on tests. Findings in other sites have corroborated these findings.
  • Fluoride is likely to have a significant impact on children whose brains are still developing. Some studies are even seeking to examine the impact of fluoride consumption on the unborn. 
  • Most water purifiers do not eliminate fluoride from tap water.
  • Not all bottled waters are fluoride-free. 

Notable Victories

  • The Environmental Protection Agency has proposed a ban on Sulfuryl Fluoride, which is used routinely as a pesticide. The substance leaves behind traces of fluoride on treated substances, which include coffee, nuts, and dried fruit. 
  • The U.S. government has decided to reduce fluoride in the public water supply. The decision comes after a report was published by the Centers for Disease Control, which stated that two out of three children have unnatural streaks or spots on their teeth from over-exposure to fluoride.

Fracking

Issue # 1 up for discussion: Fracking.

Here's what you need to know

  • Fracking combines hydraulic fracturing with horizontal drilling
  • Fracking requires the use of a number of dangerous chemicals (596 at last count)
  • Fracking may allow these chemicals to find their way into groundwater
  • Water which has been contaminated with fracking chemicals is highly flammable. It has been shown to kill plant and animal life, and prolonged exposure causes irreversible brain damage in human beings.
  • The people have the power to demand legislation that halts fracking until concerns can be addressed
The news isn't all bleak. The New York State Assembly voted on a moratorium last November. Furthermore, the state senate passed a similar bill last August. The moratorium is strongly backed by environmental organization, who are dismayed by the possible effects of fracking on the environment. The measure is not without opposition, however. The Independent Oil and Gas Association of New York, a trade group, has warned that nearly 5,000 industry jobs might be threatened by the legislation. The state might also lose up to $1 million in revenues from drilling permits.
