Are you aware of the health dangers of fluoride? Did you know that fluoride can damage fertility, destroy bones and cause early puberty in children?
Water fluoridation has been banned in many countries including: China, Austria, Belgium, Finland, Germany, Denmark, Norway, Sweden, the Netherlands, Hungary, and Japan. Nearly all of Europe’s water supply is fluoride-free.
And yet, fluoride is omnipresent in the American food supply. It’s in our water, in juice, soda, wine and coffee, in soups and processed food, and in baby formula. The majority of American cities have fluoridated water.
Sources of Fluoride
Many people think they can avoid fluoride by just using fluoride-free toothpaste. However, fluoride isn’t just in toothpaste. Almost all of the beverages sold in stores and restaurants are made with tap water. People who drink those beverages ingest a fair amount of added fluoride.
1. Accumulation of Fluoride in the Body
Fluoride accumulates in the body. Healthy adult kidneys excrete 50 to 60% of the fluoride ingested each day (Marier & Rose 1971). Any remaining fluoride accumulates in the body, typically in the bones and pineal gland (Luke 1997, 2001). Babies and children excrete less fluoride from their kidneys and absorb up to 80% of ingested fluoride into their bones (Ekstrand 1994). The concentration of fluoride in the bones increases over a lifetime (NRC 2006).
2. Fluoride and Bottle-fed Babies
Bottle-fed babies receive the highest doses of fluoride. Since they have a liquid diet, formula-fed babies have the highest exposure to fluoride. Infant exposure to fluoridated water has been repeatedly found to be a major risk factor for developing dental fluorosis later in life (Marshall 2004; Hong 2006; Levy 2010). As a result, dental researchers have recommended that parents of newborns not use fluoridated water when reconstituting formula (Ekstrand 1996; Pendrys 1998; Fomon 2000; Brothwell 2003; Marshall 2004).
The American Dental Association (ADA), the biggest advocates of fluoridation, sent a November 6, 2006 email alert to its members advising that parents should make baby formula with “low or no-fluoride water.”
3. Fluoride and Reproductive Problems
Fluoride given to animals at high doses destroys the male reproductive system. Fluoride damages sperm and increases the rate of infertility in a number of species (Kour 1980; Chinoy 1989; Chinoy 1991; Susheela 1991; Chinoy 1994; Kumar 1994; Narayana 1994a,b; Zhao 1995; Elbetieha 2000; Ghosh 2002; Zakrzewska 2002).
A U.S. epidemiological study showed increased rates of infertility among couples living in areas with 3 ppm or more fluoride in the water (Freni 1994). Two studies showed reduced level of circulating testosterone in males living in high fluoride areas (Susheela 1996; Barot 1998). A study of fluoride-exposed workers reported a “subclinical reproductive effect” (Ortiz-Perez 2003).
4. Fluoride and Brain Damage
“It is apparent that fluorides have the ability to interfere with the functions of the brain.” — the National Research Council (2006)
The US Environmental Protection Agency (EPA) lists fluoride among about 100 chemicals for which there is “substantial evidence of developmental neurotoxicity.” Experiments on animals reveal that fluoride accumulates in the brain and alters mental behavior (Mullenix 1995). There have been over 100 animal experiments showing that fluoride damages the brain and impacts learning and behavior.
Advocates of fluoridation counter that these animal studies are invalid because high doses of fluoride were used. However, it takes 5-20 times more fluoride to reach the same plasma levels in rats as in humans (Sawan 2010). One animal experiment found effects at very low doses of fluoride (Varner 1998). In this study, rats were fed for one year with 1 ppm fluoride in their water (the same amount used in tap water fluoridation), using either sodium fluoride or aluminum fluoride. These rats had changes to their kidneys and brains, an increased uptake of aluminum in the brain, and the formation of beta-amyloid deposits which are associated with Alzheimer’s disease.
5. Fluoride and Lowered IQ
There have been 24 studies from China, Iran, India and Mexico that show an association between fluoride exposure and reduced IQ. One research team (Xiang 2003a,b) estimated that fluoride may lower IQ at 1.9 ppm (parts per million), while a recent preliminary study (Ding 2011) found a lowering of IQ in children drinking water at levels ranging from 0.3 to 3 ppm. The authors of this latter study reported that for each increase of 1 ppm fluoride measured in the urine there was a loss of 0.59 IQ points. According to the National Research Council (2006), “the consistency of the results [in fluoride/IQ studies] appears significant enough to warrant additional research on the effects of fluoride on intelligence.”
