First-ever government review of fluoride/thyroid toxicology shows risk
2008-05-19 15:54:10 – There is clear evidence that small amounts of fluoride, at or near levels added to U.S. water supplies, present potential risks to the thyroid gland, according to the National Research Council’s (NRC) first-ever published review of the fluoride/thyroid literature.(A)
Fluoride, in the form of silicofluorides, injected into 2/3 of U.S. public water supplies, ostensibly to reduce tooth decay, was never safety-tested.(B)
“Many Americans are exposed to fluoride in the ranges associated with thyroid effects, especially for people with iodine deficiency,” says Kathleen Thiessen, PhD, co-author of the government-sponsored NRC report. “The recent decline in iodine intake in the U.S could contribute to increased toxicity of fluoride for some individuals,” says Thiessen.
“A low level of thyroid hormone can increase the risk of cardiac disease, high cholesterol, depression and, in pregnant woman, decreased intelligence of offspring,” said Thiessen.(C)
