In 2012 more than 67 percent of Americans received fluoridated water,1 and of those, more than 11 million people were getting fluoride at or above the “optimal” level of 0.7-1.2 milligrams per liter (mg/L), according to the US Centers for Disease Control and Prevention (CDC).
Then, in April this year, the US Department of Health and Human Services (HHS) announced that this “optimal” level of fluoride, recommended since 1962, had in fact been set too high, resulting in 40 percent of American teens showing signs of overexposure2–a condition known as dental fluorosis.
So, for the first time in nearly 55 years, the US government lowered its recommended level of fluoride in drinking water3,4,5 to a maximum of 0.7 mg/L. The question is, will this new level protect everyone from overexposure?
Considering the fact that virtually all Americans get fluoride from other sources such as toothpaste, dental rinses, processed foods, and beverages, and the fact that fluoride accumulates in your body over time, chances are this lower level will still pose a health risk for many.
The first public experiment was allowed to continue for more than half a century before a reevaluation of the dosage was done. Now, we’ll have to wait another decade before they try to determine whether 0.7 mg/L is really “optimal” or not.
Remember, fluoride is a toxic drug administered without prescription or dosage control, so really, the optimal dosage of fluoride in water is actually zero…
Fluoride Is a Toxic Drug Dispensed Without Prescription or Dosage Control
Fluoride is added to drinking water in an albeit futile attempt to prevent a disease (tooth decay), and as such becomes a medicine by FDA definition—and like most other drugs, there may be side effects.
The severity of those side effects depends on your age, size/weight, health status, and of course the amount of water you consume.
While proponents claim water fluoridation is no different than adding vitamin D to milk, fluoride is not an essential nutrient that many are deficient in, which is the case with vitamin D. Moreover, fluoride isn’t even approved by the FDA for the prevention of cavities!
What’s worse, it’s quite obvious that when you add fluoride to drinking water, you cannot control the dose that people are getting, and this alone is one of the reasons why fluoride should not be added to drinking water at any level.
Doing so can have significant consequences, but the health effects are largely hidden in the general disease statistics, since none of the US agencies promoting fluoridation are tracking and correlating the health outcomes of fluoride exposure.
What Happens to the Fluoride in Your Body?
Approximately 98 percent of the fluoride you consume is absorbed into your blood through your gastrointestinal tract. From there, it enters your body’s tissues.
On average, about 50 percent of the fluoride you ingest each day gets excreted through your kidneys, so kidney function is another important factor when it comes to the build-up of fluoride and its potentially toxic effects. The remainder accumulates in your teeth and bones,6 pineal gland,7 and other tissues—including your blood vessels, where it can contribute to calcification.
According to a 500-page long scientific review8 by the National Research Council of the National Academies (NRC), published in 2006, fluoride is an endocrine disruptor that can affect your thyroid function9 and even your blood sugar levels.
British researchers recently warned that 15,000 Britons may be needlessly afflicted with hypothyroidism as a result of drinking fluoridated water.10 Thyroid dysfunction is also rampant in the US,11 so from a public health standpoint, it makes no sense whatsoever to medicate the entire population with a drug that can either induce or exacerbate this condition.
Even more disturbing, 43 human studies12 have linked moderately high fluoride exposures with reduced IQ in children, and over 100 animal studies have linked it to brain damage.
Recent research13 has also linked water fluoridation with higher prevalence of ADHD. Using a predictive model, the researchers show that every one percent increase in the portion of the US population drinking fluoridated water in 1992 was associated with 67,000 additional cases of ADHD 11 years later, and an additional 131,000 cases 19 years later.
