New Study: Fluoridated Water and Toothpaste May Contribute to Growth of Kidney Stones

(University of Tasmania) A new study published in the Journal of Analytical Chemistry indicates that fluoride ions found in fluoridated water and toothpaste may lead to an increase in Urinary Stone Disease (USD). The study, “Determination of fluoride ions in urinary stones by ion chromatography”, was conducted by chemists from Russia and Australia, led by Pavel Nesterenko at the University of Tasmania.

Urinary stones are small crystallized deposits of minerals, especially calcium and magnesium, that can form in the urinary system and cause extreme pain. The crystals form as a result of dehydration which causes large quantities of minerals in foods to concentrate into crystals. Besides calcium and magnesium, the stones can also contain uric acid, cystine and fluorides. By studying which compounds create the stones researchers hope to better understand how to avoid them.

The chemists examined urinary stones using a technique known as ion chromatography (IC). The team states that “it is known that fluoride ions posses exceptive (sic) affinity to calcium ions, which gives a certain ground to consider hyperfluorosis (chronic disease developing as a result of a long term excessive ingress of fluorine and its compounds into the body) to be one of the possible causes of Urinary Stone Disease (USD).”

The team studied 20 urinary stones from patients at a Russian hospital using IC and conductivity detection. They discovered fluoride ions in 80% of the stones. The majority of the stones had low levels of fluorides but two contained high concentrations, above 0.5 mg. This could be due to high levels of fluoride in patients urine, possibly from drinking water containing fluorides and ingesting fluoride toothpaste.

The Tasmanian study is the second in a matter of months to show dangers associated with Fluoride. According to a new study published in the journal General Dentistry infants are at risk of dental fluorosis due to overexposure from fluoride in commercially available infant foods.

The researchers in that study analyzed 360 different samples of 20 different foods ranging from fruits and vegetables, chicken, turkey, beef, and vegetarian dinners. All of the foods tested had detectable amounts of fluoride ranging from .007-4.13 micrograms of fluoride per gram of food. Chicken products had the highest concentrations of fluoride, followed by turkey. The high levels found in the chicken and turkey can be attributed to “fluoride-saturated bone dust” involved in the process of mechanically separating the meat.

The substances added to municipal water supplies known by the name fluoride are actually a combination of unpurified by products of phosphate mining, namely hydrofluorosilicic acid, sodium fluorosilicate, and sodium fluoride. In the United States thousands of tons of fluorosilicic acid is recovered from phosphoric acid plants and then used for water fluoridation. During this process the fluoride ion is created.

This process of taking waste from the phosphate industry and putting it into drinking water has long been criticized for it’s effects on human health, and that of the environment. It is well known that water fluoridation has led to dental fluorosis for millions of children. This discoloring of the teeth was called “cosmetically objectionable” by the Centers for Disease Control. Beyond the cosmetic effect there have been a number of studies indicating health issues ranging from arthritis, brain problems,reduced thyroid or overactive thyroid, kidney problems and bone cancers.

While proponents of water fluoridation have long pointed to an apparent drop in tooth decay in fluoridated nations as proof of it’s validity, those claims have been proven wrong by the World Health Organization. The Center for Disease Control and Prevention has stated the fluoride in the water is directly related to better teeth quality however, the WHO released it’s own study showing that tooth decay rates have dropped in all western nations, whether fluoridated or not.

The push back against adding fluoride to the water supply has become an international struggle. In southwest Ireland, in the area known as West Cork, lies a rural town that has been the center of a new movement against water fluoridation. Bantry, Ireland has become the first fluoride free town in all the country. Owen Boyden, and the West Cork Fluoride Free Campaign launched the effort in Bantry and have plans to take the campaign to other towns in West Fork.
