Scientific American editors have written than “Some recent studies suggest that over-consumption of fluoride can raise the risks of disorders affecting teeth, bones, the brain and the thyroid gland.”
After examining hundreds of studies, a National Research Council committee concluded that “fluoride can subtly alter endocrine function, especially in the thyroid.”
The presence of fluoride in foods, beverages, medicines, water, and dental products can result in over-consumption. A series of epidemiological studies have associated high fluoride exposures with lower IQ, as well as an increased risk of bone fracture.
