The fluoridation of water supplies began more than 60 years ago, and helped usher in the beginning of the “better living through chemistry” era in which we have found ourselves. Another benchmark of this era is the meteoric rise in neuro-developmental disabilities such as autism, attention deficit hyperactivity disorder (ADHD), bi-polar disorder, dyslexia, and other cognitive impairments that have afflicted millions of children worldwide with increasing frequency. Now scientists have documented the connection between these two events, in a study published this month in the journal Lancet Neurology.
The study led its authors, Dr. Philippe Grandjean of the Harvard School of Public Health and Dr. Philip Landrigan of the Icahn School of Medicine, to classify fluoride as a developmental neurotoxin, meaning it is toxic to brain cells. As a result, cognitive development is impaired and intelligence quotient (IQ) is reduced.
They write, “A meta-analysis of 27 cross-sectional studies of children exposed to fluoride in drinking water, mainly from China, suggests an average IQ decrement of about seven points in children exposed to raised fluoride concentrations.” The majority of these studies showed levels of fluoride at concentrations which the US Environmental Protection Agency (EPA) currently allows in the US, which is less than 4 milligrams per liter.
According to the Centers for Disease Control (CDC) 276 million Americans are still consuming fluoridated drinking water. The CDC along with the American Dental Association has long been a strong advocate for water fluoridation.
Fluoride joins the rouges gallery of industrial chemicals injuring developing brains
The same research team conducted a systematic review in 2006, and identified five industrial chemicals as developmental neurotoxins: lead, methyl mercury, polychlorinated biphenyls, arsenic, and toluene. Since then, epidemiological studies have documented six additional developmental neurotoxins: manganese, chlorpyrifos, dichlorodiphenyltrichloroethane, tetrachloroethylene, the polybrominated diphenyl ethers, and now fluoride. The scientists postulate that even more neurotoxicants remain undiscovered.
Harm from neurotoxins is often untreatable and the damage is permanent. The pharmaceutical drugs that have become so popular and profitable for treating chemically injured brains do nothing to heal. Instead they simply mask the symptoms temporarily but ultimately cause even greater dysfunction through their side effects, one of which is brain shrinkage.
Gandjean and Landrigan note their concern that children worldwide are “being exposed to unrecognized toxic chemicals that are silently eroding intelligence, disrupting behaviors, truncating future achievement, and damaging societies.” According to them, it is crucial to control the use of all harmful chemicals to protect children’s brain development.
To control the pandemic of developmental neurotoxicity, they are proposing a global prevention strategy that would include mandatory testing of chemicals and the formation of a clearinghouse to evaluate them for potential neurotoxicity, alone and in combination. “Fluoride seems to fit in with lead, mercury, and other poisons that cause chemical brain drain,” Grandjean states. “The effect of each toxicant may seem small, but the combined damage on a population scale can be serious, especially because the brain power of the next generation is crucial to all of us.”
Commenting on the classification of fluoride as a dangerous neurotoxin, Fluoride Action Network Executive Director Paul Connett, PhD, said “adding more fluoride to American’s already excessive intake no longer has any conceivable justification. We should follow the evidence and try to reduce fluoride intake, not increase it.”
Fluoride is not easily eliminated from the body. It accumulates in bones and teeth, and even in the pineal gland. As many as 41% of teens and adults who have grown up with water fluoridation have dental fluorosis, a mottling of their tooth enamel. Other conditions linked to long term intake of fluoridated water are DNA damage, cancer, osteoporosis, Alzheimer’s disease, endocrine disruption (particularly to the thyroid), inability to focus, accelerated aging, lowered immunity, sleep disorders, and muted psychic awareness and spiritual development.
