The Harmful Effects of Fluoride Continue to Mount

Research linking fluoride with harmful long-term side effects continues to mount, with more undeniable evidence of fluoride’s neurotoxicity published as FAN’s historic trial with the EPA draws closer.

Ending the addition of hazardous fluoridation chemicals — primarily hydrofluorosilicic acid — to the public’s drinking water will be one of the greatest public health achievements of the 21st century.

With each passing month, the case against artificial fluoridation builds as new research showing harm is published, legal action advances, overfeeds and spills are exposed and local fluoride-free campaigns spread throughout the world.

Mounting Evidence of Harm

A number of significant studies — two of which were funded by the U.S. government (the National Institutes of Health, or NIH) — have been published in the last 8 months linking fluoride exposure to lowered IQ, attention deficit hyperactivity disorder (ADHD) and thyroid problems, and showing that pregnant women and infants in “optimally” fluoridated communities are exposed to significantly more fluoride than those in non-fluoridated communities.

In February 2019, a string of news stories — triggered by a U.S. Centers for Disease Control and Prevention (CDC) report admitting that at least 40% of children are overexposed to fluoride — focused on kids swallowing too much toothpaste and neglected the significant exposure from fluoridated tap water.

Regardless, the defenders of water fluoridation are missing the real story. Dental fluorosis is a biomarker of overexposure to fluoride and the “elephant in the room” is what damage fluoride is doing to other tissues.

Recent scientific research indicates that exposure to fluoridated water may lower thyroid function, particularly in those with an iodine deficiency. A new study also found that significantly more infants, particularly those under 6 months of age, will exceed the upper limit set by the Institute of Medicine for fluoride when consuming formula reconstituted with the “optimal” 0.7 parts per million (ppm), greatly increasing their risk of side effects.

There are now over 350 published studies on fluoride’s effect on the brain: 130 human studies, over 200 animal studies and 33 cell studies.

This includes a major U.S. government funded mother-offspring study conducted in Mexico City. This rigorous study — which controlled for many possible confounders — found a very strong association between fluoride levels in mothers’ urine and lowered IQ for their offspring.

The fluoride levels in this study also correspond to levels in pregnant women living in “optimally” fluoridated areas in Canada according to an October 2018 paper.

The same research team at University of Toronto’s Dalla Lana School of Public Health has since released additional findings that confirm and strengthen their 2017 fetus/IQ study. Very young children, aged 1 to 3 years, also show loss of IQ. In other words, their study now covers the ages of the offspring from 1 to 12 years.

For the ages of 1 to 3 years, for every 1 mg/L increase in the urine fluoride level of their pregnant mothers, the children averaged 2.4-point lower IQ scores. The finding was statistically significant and accounted for potential confounding factors.

They concluded, “Our findings add to our team’s recently published report on prenatal fluoride and cognition at ages 4 and 6–12 years by suggesting that higher in utero exposure to F has an adverse impact on offspring cognitive development that can be detected earlier, in the first three years of life.”

This was followed up by another published paper that linked higher levels of urinary fluoride during pregnancy with more symptoms of ADHD — the second study to do so.

World Expert on Lead Now Warns of Fluoride’s Neurotoxicity

As if the recent research condemning fluoridation couldn’t get any worse, a major review article in the journal Pediatric Medicine by David Bellinger, Ph.D., professor of neurology at Harvard Medical School, has included fluoride in a list of chemicals known or suspected to interfere with the neurodevelopment of children.

Bellinger, recognized as one the leading experts in the world on the neurotoxicity of lead, holds 3 important positions in Boston: two at Harvard and one at Boston Children’s Hospital.

In his review of fluoride’s neurotoxicity, Bellinger cites the meta-analysis of 27 IQ studies from China and Iran; a follow-up study in China he co-wrote and the more recent U.S. government-funded mother-offspring studies from Mexico City.

While the mainstream media covered the Choi meta-analysis from 2012, they have ignored all the major neurotoxicity studies published since then. Meanwhile, they continue to go overboard on low-quality studies that focus on tooth decay.

According to Paul Connett, Ph.D., Fluoride Action Network (FAN) director,

“We hope that when more pediatricians read about these important neurotoxicity studies — especially the mother-offspring studies — that they will warn women of child-bearing age to avoid all sources of fluoride during pregnancy and parents not to bottle-feed their infants with formula prepared with fluoridated tap water.”

There’s no doubt about it: Fluoride should not be ingested. Even scientists from the EPA’s National Health and Environmental Effects Research Laboratory have classified fluoride as a “chemical having substantial evidence of developmental neurotoxicity.”

These new scientific findings further strengthen the evidence of fluoride’s neurotoxicity. The fluoride levels at issue in these studies are within the range that pregnant women in the U.S. are receiving, so the findings are clearly relevant to our ongoing legal case against the U.S. Environmental Protection Agency (EPA).

In November 2016, the FAN together with a coalition of organizations and private citizens, presented a petition to the EPA calling on the agency to exercise its authority to prohibit the addition of fluoridation chemicals to the public’s drinking water supplies under Section 21 of the Toxic Substances Control Act (TSCA).
