Mothers Exposed to Fluoride During Pregnancy Give Birth to Lower IQ Children
New studies show that fluoride damages babies before they are born.
Fluoride is well known to be more toxic than lead and slightly less toxic than arsenic. Dozens of independent studies published in peer-reviewed journals have clearly shown that fluoride reduces IQ. So it should have come as no surprise that mothers exposed to fluoride would deliver babies with brain damage.
The problem is that in the United States, Canada, the United Kingdom, Australia, Singapore, Hong Kong, Chile and a few other countries, most of the population is deliberately exposed to harmful levels of fluoride through their drinking water and have additional exposure to it from air, food, bottled beverages and toothpaste.
Fluoride is a fluorine compound. The element fluorine is so unstable that it is not really found in nature unless it has bonded to some other element. In nature, it is found mostly as calcium fluoride.
Fluorine started to be manufactured in volume only after the United States needed it to enrich uranium to produce the atomic bomb. It is also now widely used in phosphate-fertilizer plants and is found in about 100 chemicals. It is the primary active ingredient in many pharmaceuticals, including antidepressants known to cause homicidal and suicidal compulsions.
Prior to World War II, fluoride was widely considered to be a dangerous toxin to be avoided and was thought by some to make people docile and suggestible. Even the American Dental Association (ADA) was dead set against the idea of adding fluoride to water or toothpaste.
Fluoride is still widely distributed in U.S. water supplies and in dental products because it is said to reduce tooth decay, but the reality is that it doesn’t actually reduce tooth decay. Data clearly shows that people who live in countries without water fluoridation have the same number of or fewer cavities.
The dental industry uses fake science and cherrypicked data while ignoring the vast number of studies that don’t support its position.
Although still not widely distributed, several scientific studies have revealed that fluoride is an endocrinedisrupting chemical. The category of endocrinedisrupting chemicals includes items such as mercury, organophosphate pesticides, lead, arsenic, dioxin and Bisphenol A (also known as BPA). What they share is exactly what their name defines: the ability to disrupt the human endocrine system.
This disruption can take many different forms. These chemicals can cause certain hormones to be released prematurely or in larger quantities than is appropriate, slow the production of hormones necessary for proper physical functions, imitate hormones (the dangerous chemicals replace the “good” ones they are copying), change one hormone into another, affect the way “hormone signaling” happens, bind to essential hormones but drastically alter their effectiveness and compete with other items in the body for essential nutrients. Such chemicals also end up accumulating in organs that produce other hormones, causing them to malfunction.
Besides acting as an endocrine disrupter, fluoride has also been shown more recently to function as a dangerous neurotoxin. It has been shown to impact both short-term and working memory. It has also been connected to attention deficit hyperactivity disorder (ADHD) and the prevalence of lower IQS in children exposed to the chemical. There are, in fact, more than 300 animal and human studies that show that too much fluoride can cause brain damage (especially in people who are iodine-deficient or whose aluminum level is too high) and can make it harder to learn and recall information.
One might imagine that the U.S. government was operating completely “asleep at the wheel” regarding the dangers of fluoride. That is not the complete story, however. In April 2015, federal authorities finally admitted that the original recommended “optimal” exposure to fluoride, going back to 1962, was higher than it should have been. They did this after determining that over 40% of U.S. teenagers had been exposed to much higher levels of fluoride than they should have been and were demonstrating symptoms of dental fluorosis. In some areas of the country, that overexposure rate was over 70%.
Based on this, the U.S. Department of Health and Human Services (HHS) recently lowered the recommended amount of fluoride put in drinking water. The previous value had allowed for up to 1.2 milligrams of fluoride per liter of water. The new recommended level is 0.7 mg/l, a decrease of ~42%.
The idea that there might be serious consequences for babies in utero who were exposed to higher levels of fluoride was an easy jump to make. Previous data
had already called out the likely role of fluoride in impairing fetal brain development and producing lower IQS. So, when a study published in September 2017 in Environmental Health Perspectives came out saying that fluoride is a toxin that should be avoided at all costs by pregnant women, it was not a surprise to those familiar with the science involved.
The study covered data from almost 300 mothers and their children in Mexico. It was conducted by Howard Hu, founding dean of the Dalla Lana School of Public Health, University of Toronto.
As a background, while Mexico does not fluoridate its public drinking water supplies, there is still a great deal of fluoride in the Mexican food and hygiene ecosystem. There is still the fluoride that naturally occurs in water, along with fluoridated salt, dental products, food supplements, pesticides and even tea. That amounts to quite a bit of fluoride still making its way into the bodies of Mexican mothers during pregnancy.
In this study, the mean level of fluoride in the urine of the mothers included in the investigation was 0.9 mg/l. The observation was made that with some 75% of U.S. drinking-water supplies now being fluoridated, the level of fluoride contamination in American mothers was not likely to be a great deal different than that of the Mexican mothers in the study.
What researcher Hu noted in his study was that “the fetal system tends to be more sensitive to environmental toxicants than once the child is born.” He went on to conclude, based on the analysis, that a child of a mother drinking water with 1 part per million (ppm) of fluoride would have an IQ running 5 to 6 points lower than a child born to a mother drinking only fluoride-free water. Further, as the level of fluoride in the water increased, the effect was worse. For every 0.5 mg/l increase in fluoride concentration in the water beyond 0.8 mg/l, there was another 2.5-point reduction in IQ and a cognitive index score reduction of 3.15 points. A detailed scatter graph backed up the linear relationship between Iq-level impact and fluoride concentration.
Comparing that to what has been a decades-long exposure to 1.2 mg/l of fluoride in the water as a “safe” level, that would correspond to a 0.4 mg/l increase over the base number noted above.
Does this mean the new “safe” maximum level of fluoride exposure the HHS has set – 0.7 mg/l – is safe enough? Hardly. It simply means that going over that level is worse. The best scenario would be zero exposure to fluoride.
After seeing Hu’s study and considering its implications, the ADA, which has a close relationship with the fluoride supply industry, has said the findings are not relevant because the source of the fluoride ingested was not identified. That, of course, makes little sense, considering that it is the fluoride itself that is the issue, as well as its ready ability to be absorbed into the bloodstream. It has nothing to do with where it comes from. So the ADA, which by its endorsement encourages putting even more fluoride into pregnant women’s bodies via their toothpastes and other dental products, is making matters worse.
In some ways, this is feeling like a rerun of the situation when the controversial antimicrobial agent triclosan and its chemical sibling triclocarban ended up being banned last year from hand and body washes and bar soaps. When the FDA banned the items in September 2017, it pointed out that triclosan, triclocarban and the other chemicals removed from consumer products are not just unnecessary. The agency also noted that there is evidence that those chemicals disrupt hormone cycles and can cause muscle weakness.
The FDA ban did not succeed everywhere, however. The same triclosan chemical now banned from soap products is still allowed in toothpaste as an additive placed there for precisely the same marketing reason: that it allegedly helps those brushing their teeth to kill bacteria during the tooth-brushing process. This is again despite triclosan apparently causing hormone disruption – just as the scientists are proving now, again and again, for the presence of fluoride in the water.
So how did triclosan and similar chemicals make it through unscathed as part of oral hygiene products? None other than via the ADA, along with lobbying by the manufacturers of the triclosan toothpastes themselves, which are even patented so others can’t use this approach even if it were safe.
The story on triclosan is still to be investigated in more detail. For now, the conclusions on the many forms of damage that fluoride can do to all of us – and our unborn children – are becoming clearer than ever.
Toothpaste is available without fluoride, triclosan and other poisons.
