Water Problems - Fluoride
What are the Concerns Associated with the Addition of Fluoride to the Water Supply?
The most recognized problem with the ingestion of too much fluoride is dental fluorosis. This condition is characterized by the failure of tooth enamel to crystallize properly in permanent teeth. The effects range from chalky, opaque blotching of teeth to severe, rust-colored stains, surface pitting and tooth brittleness.
This condition, though worrisome, may not be the key concern , at least according to some researchers. Dr. Phyllis Mullenix believes, based on her research, that fluoride acts in a way that lowers the I.Q. of children ("Neurotoxicity of Sodium Fluoride in Rats", Mullenix, P. Neurotoxicology and Teratology, 17 (2), 1995).
Dr. William Marcus, believes that a study conducted by Battelle for the National Toxicology Program on the toxicology of fluoride shows that there were dose-related increases in bone cancer in male rats. Dr. Marcus also questions the removal by peer reviewers of cancers at other sites in the rats as well. Especially worrisome to Dr. Marcus is the fact that that levels of fluoride that caused the cancers in the rats were lower than those seen in humans who ingested lower amounts, but for a longer period. These levels are generated because fluoride is accumulated in the body and is not secreted.
Dr. Marcus was formerly the chief toxicologist for the EPA's Office of Drinking Water, but was fired in 1991 after insisting that an unbiased evaluation of fluoride's cancer potential be conducted. Marcus fought his dismissal, and was able to be reinstated after demonstrating in court that it was politically motivated.
An article in the Irish Times of Dublin on August 16, 1999, reports that Dr. Hans Moolenburgh's research in Holland found that up to 4 percent of people using fluoridated water experienced health problems. These problems ranged from gastrointestinal disorders to mouth sores to rashes to headaches to forms of arthritis to more serious concerns such as cancers and neurological complaints.
The Journal of the American Medical Association (1990-1992) has reported a greater incidence of hip fractures in fluoridated areas in the U.S. and Britain. TheNew England Journal of Medicine (1990) reported that fluoride treatment of osteoporosis patients resulted in higher hip fracture rates. The governmental National Institute of Environmental and Health Sciences (1990) has shown that fluoride causes cancer. Former promoters of fluoridation have since found that fluoridation does not reduce tooth decay (1987-1988). Scientist at the U.S. Environmental Protection Agency (1989-1993) have come out against fluoridation because they have confirmed that it does not reduce tooth decay and that there is clear evidence that fluoride causes cancer.
It
is imperative that you filter your water to a quality that you can rely
on and in a way that when municipal systems fail you will still be
safe. Reverse Osmosis is best and most effective for this.
