Fluoride in the water is a threat to health
Balancing the pros and cons of fluoride in our water systems
Sir, Dr Nigel Carter speaks passionately in favour of fluoridating the water supply (Public sector, April 17). It would appear that he is not familiar with the findings of the 2006 US National Research Council (NRC) report on fluoride toxicity, which cites a growing body of scientific research linking fluoride exposure to disruption of the nervous and endocrine systems, including the brain, thyroid and adrenal glands. Data presented in the report suggest that doses of fluoride associated with thyroid disturbances are now exceeded by many Americans, particularly children, living in so-called “low-fluoride” (1ppm) areas. Even more worrying is the association of increased rates of osteosarcoma (bone cancer) in young males in fluoridated areas, as revealed in a recently published US study. Dr Carter also fails to mention that removal of aesthetically significant dental fluorosis has to be paid for privately.
How can fluoride be safe at 1ppm in water supplies when prolonged intake at 2ppm can lead to mottled or brown discoloration of the enamel in developing teeth and at levels of more than 8ppm may lead to bone disorders and degenerative changes in the kidneys, liver, adrenal glands, central nervous system and reproductive organs? There is no realistic safety margin in fluoridated water — its intake cannot be controlled. People with diabetes or kidney problems are at particular risk, as are non-breast-fed babies.
