In 2010, the Environmental Protection Agency placed fluoride on their list of developmental neurotoxins — a list of chemicals with substantial scientific evidence for the ability to injure the developing brain of fetuses and children.
In 2006, the National Research Council determined fluoride to be an endocrine disruptor, with its most known target being the thyroid gland — the gland that regulates our weight, our fertility, our mood and our energy levels.
A common misconception is that the dose of fluoride in our water is low enough to avoid these toxic effects of fluoride. But in fact, as with lead and arsenic, we know now that even very small doses of toxins over time have the ability to do great harm to our health, particularly to our developing brains, our immune systems and our endocrine systems.
New science tells us at least one way in which fluoride exposure is affecting our children’s brains — by decreasing a child’s IQ. Forty-one percent of U.S. children have dental fluorosis — a white speckling of the permanent teeth — as a result of consuming fluoride. Recent science out of the Harvard School of Public Health shows a direct correlation between the severity of a child’s dental fluorosis and the degree of IQ point loss on standardized IQ tests. This risk of IQ loss disproportionately affects minority children, with 58 percent of African-American children having dental fluorosis, as opposed to 41 percent of Caucasians.
In a time when one in six U.S. children has a neurodevelopmental brain disease, which include attention deficit hyperactivity disorder, autism spectrum disorders, and learning disabilities, we cannot afford to put a chemical known to increase the risk of developing such diseases in our tap water, our bottled drinks, our soups and our juices that our children drink every day.
In a time when one in eight women will develop thyroid disease, and over 50 percent of us suffer from obesity, we cannot afford to put in our water any dose of a chemical known to impair thyroid gland function.
The Centers for Disease Control tells us that water fluoridation, at best, reduces the rate of cavities in a person by 25 percent. That is three instead of four cavities. Is one less cavity worth risking a child’s long-term brain health or our thyroid health?
