The “investigative” team at WCVB TV in Boston ran a story yesterday about an unknown substance in fluoride imported from China. “Team 5 Investigates found the Amesbury Water Department pulled fluoride from its system amid concerns about its supply from China,” the news station reported. “Department of Public Works Director Rob Desmarais said after he mixes the white powder with water, 40 percent of it will not dissolve.” Desmarais said the residue clogs his machines and makes it difficult to get a consistent level of fluoride in the town’s water.

| A screen capture from the WCVB TV report reveals fluoride added to drinking water is a deadly toxin. | |
In the video report below, WCVB mentions melamine in food products and the heavy metal cadmium in toys imported from China while completely ignoring the larger and more important issue — fluoride is an extremely dangerous toxin that kills.
“Fluoride is added to the water most of us drink because the government believes it’s a safe and inexpensive way to prevent tooth decay.”
Fluoride does not prevent tooth decay. According to numerous studies, water fluoridation actually increases tooth decay. The AMA and others fallaciously claim that fluoride added to over 62% of U.S. water supplies reduces tooth decay. However, no less than six studies from dental journals show it does not and, in fact, may increase the likelihood of dental cavities.
Exposure to fluoride often results in dental fluorosis. Large numbers of U.S. young people — estimated up to 80 percent in some cities — now have dental fluorosis, the first visible sign of excessive fluoride exposure. Dental fluorosis consists of damage to tooth-forming cells, leading to a defect in tooth enamel. It is also an indicator of fluoride damage to bones.
WCVB TV’s own report reveals that fluoride is a deadly chemical. Near the beginning of the video, we are shown an industrial sized bag of fluoride at the Amesbury Water Department. “Sodium Fluoride,” a label on the bag warns, “Danger! Poison-Toxic by Ingestion.” The label states the chemical targets the heart, kidneys, bones, central nervous system, the gastrointestinal system, and teeth.
Studies reveal fluoride also attacks the immune and respiratory systems. It negatively affects blood circulation and accumulates in the bones. It attacks thyroid function. Fluoride also accelerates aging. Austrian researchers proved in the 1970s that as little as 1 ppm fluoride concentration can disrupt DNA repair enzymes by 50%. When DNA can’t repair damaged cells, advanced aging occurs. Researchers from Harvard University and the National Institutes of Health knew in the 1960s that fluoride disrupted collagen synthesis and increased aging.
Instead of the in-your-face danger of fluoride presented in the “investigative” news report, the intrepid reporters at WCVB concentrate on the mystery substance from China and connect it to melamine and cadmium. Talk about missing the forest for the trees.
The fluoride added to 90% of drinking water is hydrofluoric acid which is a compound of fluorine that is a chemical byproduct of aluminum, steel, cement, phosphate, and nuclear weapons manufacturing. “In this form, fluoride has no nutrient value whatsoever. It is one of the most caustic of industrial chemicals. Fluoride is the active toxin in rat poisons and cockroach powder,” notes Prevent Disease.
Moreover, hydrofluoric acid is used to refine high octane gasoline, to make fluorocarbons and chlorofluorocarbons for freezers and air conditioners, and to manufacture computer screens, fluorescent light bulbs, semiconductors, plastics, herbicides, and remarkably toothpaste.
Fluoride is a big time neurotoxin. Substantial research reveals it results in widespread brain damage and learning disabilities. Extensive research on fluoride and the brain has been prompted by studies from China, India, Iran, and Mexico discovering that elevated levels of fluoride exposure are associated with IQ deficits in children
“Repeated doses of infinitesimal amounts of fluoride will in time reduce an individual’s power to resist domination, by slowly poisoning and narcotizing a certain area of the brain, thus making him submissive to the will of those who wish to govern him,” the chemist Charles Perkins wrote to the Lee Foundation for Nutritional Research in Milwaukee, Wisconsin, on 2 October 1954.
Perkins explained how the Nazis exchanged ideas with the Russians on mass medication of a population through drinking water prior to invading Poland in 1939. “I was told of this entire scheme by a German chemist who was an official of the great IG Farben chemical industries and was also prominent in the Nazi movement at the time. I say this with all the earnestness and sincerity of a scientist who has spent nearly 20 years’ research into the chemistry, biochemistry, physiology and pathology of fluorine — any person who drinks artificially fluoridated water for a period of one year or more will never again be the same person mentally or physically.”
Both Nazi and Soviet concentration camps maintained fluoride administration to inmates to decrease resistance to authority.
However, of vital importance to our eugenics-minded rulers, fluoride has repeatedly been found to interfere with reproduction. “A few human studies suggested that high concentrations of fluoride exposure might be associated with alterations in reproductive hormones, effects on fertility, and developmental outcomes,” the National Research Council reported in 2006. In 1994, the Journal of Toxicology and Environmental Health published a study demonstrating a correlation between fluoride and reduced fertility and birth rates.
Fluoride is no longer confined to drinking water. According to the Agricultural Research Service, as of 2004 fluoride was present in 400 separate food and beverage items.
None of this was mentioned in the WCVB TV news report. Instead we are told to worry about melamine and cadmium, both certainly dangerous but nowhere approaching the threat level posed by massive fluoride poisoning.
As for the story researchers at WCVB TV, one has to wonder if maybe their cognitive ability to get to the bottom of the real story was seriously affected by a lifetime of fluoride ingestion.
I don’t want to freak you out, but there is fluoride in Clark County’s water. It’s in there because it’s a proven measure to reduce tooth decay in children. It’s working, and nothing strange is happening to those of us who ingest the tap water.
But the rest of the state, including the Reno-Sparks area, goes without, largely because of conspiracy theories that fluoride is some sort of government plot to poison people.
Unlike those who believe the military is hiding a crashed UFO at Area 51, or those who believe the government has implanted tiny listening devices under their skin, the fluoride conspiracists are actually harming the public. They testified Monday at the Nevada Legislature against a bill to add fluoride to the water in Washoe County. A doctor, of all people, testified that fluoride is an industrial waste product and causes all kinds of terrible diseases. If I were to hazard a guess, I’d say the bill is not likely to pass because of these kooks.
As a result, kids in the Reno-Sparks area will experience higher rates of tooth decay, and thus higher dental bills. Former Assemblywoman Chris Giunchigliani, who got the bill passed in 2001 to add fluoride to Las Vegas water, didn’t mince words in response to the conspiracy theorists speaking out at the Legislature. She told the Las Vegas Sun, “It says we’re very backward.”
Yep.
Here are some comments from the site:
Over 2,300 professionals urge the US Congress to stop water fluoridation until Congressional hearings are conducted, citing scientific evidence that fluoridation, long promoted to fight tooth decay, is ineffective and has serious health risks. See statement: http://www.fluorideaction.org/statement.august.2007.html.
Also, eleven Environmental Protection Agency employee unions representing over 7000 environmental and public health professionals called for a moratorium on drinking water fluoridation programs across the country, and have asked EPA management to recognize fluoride as posing a serious risk of causing cancer in people.
Last election day, 53 US cities rejected fluoridation joining a growing list of communities saying "No," to fluoridation.
Adverse Health Effects of Fluoride:

Fluoridation 101
http://www.orgsites.com/ny/nyscof
"The National Kidney Foundation dropped its fluoridation support replacing it with this caution: “Individuals with CKD [Chronic Kidney Disease] should be notified of the potential risk of fluoride exposure.”
Scientific American editors wrote in January 2008, "Some recent studies suggest that over-consumption of fluoride can raise the risks of disorders affecting teeth, bones, the brain and the thyroid gland"
Nobel Prize winner in medicine, Dr. Arvid Carlsson, says, “Fluoridation is against all principles of modern pharmacology. It's really obsolete.”
An Online Action Petition to Congress in support of the Professionals' Statement is available on FAN's web site, http://congress.fluorideaction.net and over 19,000 individuals have signed so far."

"Yeah the Nazi's thought fluoride in the water was a great idea too. You want fluoride, go and buy it. It's in toothpaste in case you didn't know and you aren't supposed to swallow it cause it is poison. 3 to 5 grams will kill an adult and a tube of crest will kill an infant or even child if swallowed but you want it in the water so everytime you have a drink you ingest it? Your ignorance is truly a reckless hazard to the entire community. I don't want poison in my water but if you want it go and buy it for yourself you ignoramous!"

"This is not journalism , it's propaganda. As someone else already said ,if you want fluoride for dental reasons then use the toothpaste! Mr.Schumacher you really should do some research before you write more piffle.Drinking water should NEVER be fluoridated in a sane society. Vested interest perhaps, Geoff?"

CARSON CITY — Unless it’s the gold standard, few issues draw out the hard-core libertarians like the issue of fluoride in the water.
And Nevada, particularly the older and more settled northern part, has a strong contingent of those individuals who tend to liberally connect the dots on issues.
So the hearing room for testimony on Senate Bill 311, which would require the fluoridation of water in Washoe County, filled up quickly Monday.
The story goes back to 1999, when the Legislature introduced a bill that required fluoridation of water. Then-Assemblywoman Chris Giunchigliani (now a Clark County commissioner) recalls the John Birch Society coming after her and people leaving messages accusing her of trying to poison them.
“It was not pleasant,” Giunchigliani testified Monday.
To get the bill passed, she changed it to require only Clark County to add fluoride. That was done starting in 2001.
Clinging to a persistent mistrust of the natural mineral, the rest of the state has not gone to fluoride.
In 2002, 58 percent of Washoe County voters said no to fluoride.
Monday’s testimony before the Senate Committee on Health and Education began with graphic pictures showing the effect of refusal to fluoridate.
Mark Rosenberg, a former U.S. Public Health Service dental director, now with St. Mary’s Hospital in Reno, offered slides of children’s decaying teeth. He came armed with statistics — 60 percent of the U.S. population lives in an area with fluoridated water. These areas have 30 percent less childhood decay than nonfluoridated areas; Washoe County children in the Headstart program had 15 percent more cavities than Las Vegas Headstart children. (It should be noted that this is one of the rare areas in which Clark County ranks better than the rest of the state.)
Rosenberg talked about baby root canals.
“It’s important to protect the dental health of the population, particularly children,” testified Sen. Bernice Matthews, D-Reno, the bill’s sponsor.
Senators knew opposition was coming, though. Near the front of the audience sat mothers of a certain age, good posture and primly dressed, clutching Internet printouts.
Sen. Dennis Nolan, R-Las Vegas, asked dentist Tyree Davis if he has seen any negative effect of fluoridation.
“I’ve never heard of anyone growing a third eye, or anything like that,” he joked. Not getting much of a laugh, he got more serious. “Certainly no problems I’ve heard of.”
Then the opposition began testifying.
Michael Gerber, a Reno homeopathic doctor, said fluoride is actually an industrial waste product that U.S. industries favor putting in drinking water supplies as a way to dispose of it. He also claimed fluoride has been associated with osteoporosis, bone cancer, Alzheimer’s and dementia.
Nolan, however, noted that two or three generations have grown up with fluoride in their water. “There haven’t been any deformities that I’ve heard of,” Nolan said.
Janine Hansen, head of the libertarian group Nevada Eagle Forum and president of the Independent American Party, testified about the dangers of fluoride, saying they include a risk of suicide. “Brain function is vulnerable to fluoride,” she said. “This is about civil liberties, medicating people through their water,” she said.
And thus the crux of the issue — this is government ordering you to ingest something even if you don’t want it.
Assemblyman Bernie Anderson, D-Sparks, agreed that there was something particularly Nevada about the opposition to fluoridation.
“There’s a distrust of anything that the government says is good,” he said. “Why are you a better guardian of my health than I am? It’s reflexive.”
Still, Anderson, a native Nevadan, compared it to immunizations that helped eliminate diseases such as smallpox.
Giunchigliani, asked about the opposition after the hearing, had a different take.
“It says we’re very backward,” she said.
The dentists and public health advocates made their earnest arguments.
Rosenberg seemed confounded by the opposition.
“I don’t understand what they’re thinking,” he said. He noted that no fluoride in the water increases customers for the dentists. “Maybe it’s the dental association funding all this opposition.”
Up until the 1990s, no research had ever been conducted to determine the impact of fluoride on the pineal gland - a small gland located between the two hemispheres of the brain that regulates the production of the hormone melatonin. Melatonin is a hormone that helps regulate the onset of puberty and helps protect the body from cell damage caused by free radicals.
It is now known - thanks to the meticulous research of Dr. Jennifer Luke from the University of Surrey in England - that the pineal gland is the primary target of fluoride accumulation within the body.
The soft tissue of the adult pineal gland contains more fluoride than any other soft tissue in the body - a level of fluoride (~300 ppm) capable of inhibiting enzymes.
The pineal gland also contains hard tissue (hyroxyapatite crystals), and this hard tissue accumulates more fluoride (up to 21,000 ppm) than any other hard tissue in the body (e.g. teeth and bone).
After finding that the pineal gland is a major target for fluoride accumulation in humans, Dr. Luke conducted animal experiments to determine if the accumulated fluoride could impact the functioning of the gland - particulalry the gland's regulation of melatonin.
Luke found that animals treated with fluoride had lower levels of circulating melatonin, as reflected by reduced levels of melatonin metabolites in the animals' urine. This reduced level of circulating melatonin was accompanied - as might be expected - by an earlier onset of puberty in the fluoride-treated female animals.
Luke summarized her human and animal findings as follows:
"In conclusion, the human pineal gland contains the highest concentration of fluoride in the body. Fluoride is associated with depressed pineal melatonin synthesis by prepubertal gerbils and an accelerated onset of sexual maturation in the female gerbil. The results strengthen the hypothesis that the pineal has a role in the timing of the onset of puberty. Whether or not fluoride interferes with pineal function in humans requires further investigation."

“The single animal study of pineal function indicates that fluoride exposure results in altered melatonin production and altered timing of sexual maturity. Whether fluoride affects pineal function in humans remains to be demonstrated. The two studies of menarcheal age in humans show the possibility of earlier menarche in some individuals exposed to fluoride, but no definitive statement can be made. Recent information on the role of the pineal organ in humans suggests that any agent that affects pineal function could affect human health in a variety of ways, including effects on sexual maturation, calcium metabolism, parathyroid function, postmenopausal osteoporosis, cancer, and psychiatric disease.”

Fluoride & Pineal Gland - Never Studied before 1990s: (back to top)
"It is remarkable that the pineal gland has never been analysed separately for F because it has several features which suggest that it could accumulate F. It has the highest calcium concentration of any normal soft tissue in the body because it calcifies physiologically in the form of hydroxyapatite (HA). It has a high metabolic activity coupled with a very profuse blood supply: two factors favouring the deposition of F in mineralizing tissues. The fact that the pineal is outside the blood-brain barrier suggests that pineal HA could sequester F from the bloodstream if it has the same strong affinity for F as HA in the other mineralizing tissues. The intensity of the toxic effects of most drugs depends upon their concentration at the site of action.The mineralizing tissues (bone and teeth) accumulate high concentrations of F and are the first to show toxic reactions to F. Hence, their reactions to F have been especially well studied. If F accumulates in the pineal gland, then this points to a gap in our knowledge about whether or not F affects pineal physiology. It was the lack of knowledge in this area that prompted my study."

Fluoride & Pineal Gland - Accumulation of Fluoride in Soft Tissue of Pineal Gland: (back to top)
"After half a century of the prophylactic use of fluorides in dentistry, we now know that fluoride readily accumulates in the human pineal gland. In fact, the aged pineal contains more fluoride than any other normal soft tissue. The concentration of fluoride in the pineal was significantly higher (p <0.001) than in corresponding muscle, i.e., 296 ± 257 vs. 0.5± 0.4 mg/kg (wet weight) respectively."

"In terms of mineralized tissue, the mean fluoride concentration in the pineal calcification was equivalent to that in severely fluorosed bone and more than four times higher than in corresponding bone ash, i.e., 8,900 ± 7,700 vs. 2,040 ± 1,100 mg/kg, respectively. The calcification in two of the 11 pineals analysed in this study contained extremely high levels of fluoride: 21,800 and 20,500 mg/kg."

Fluoride & Pineal Gland - Analagous to Dental Fluorosis? (back to top)
"Fluoride is now introduced at a much earlier stage of human development than ever before and consequently alters the normal fluoride-pharmacokinetics in infants. But can one dramatically increase the normal fluoride-intake to infants and get away with it? The safety of the use of fluorides ultimately rests on the assumption that the developing enamel organ is most sensitive to the toxic effects of fluoride. The results from this study suggest that the pinealocytes may be as susceptible to fluoride as the developing enamel organ."
SOURCE: Luke J. (1997). The Effect of Fluoride on the Physiology of the Pineal Gland. Ph.D. Thesis. University of Surrey, Guildford. p. 176."Alongside the calcification in the developing enamel organ, calcification is also occurring in the child's pineal. It is a normal physiological process. A complex series of enzymatic reactions within the pinealocytes converts the essential amino acid, tryptophan, to a whole family of indoles. The main pineal hormone is melatonin (MT)... If F accumulates in the pineal gland during early childhood, it could affect pineal indole metabolism in much the same way that high local concentrations of F in enamel organ and bone affect the metabolism of ameloblasts and osteoblasts."
SOURCE: Luke J. (1997). The Effect of Fluoride on the Physiology of the Pineal Gland. Ph.D. Thesis. University of Surrey, Guildford. p. 5."Any adverse physiological effects of fluoride depend upon the concentration at various tissue sites. Can pinealocytes function normally in close proximity to high concentrations of fluoride?One would predict that a high local fluoride concentration would affect pinealocyte function in an analogous way that a high local fluoride concentration affects: i) bone cells, since histological changes have been observed in bone with 2,000 mg F/kg (Baud et al, 1978); ii) ameloblasts, since dental fluorosis develops following fluoride concentrations of 0.2 mg F/kg in the developing enamel organ (Bawden et al, 1992). The consequences are disturbances in the functions of bone and enamel, i.e., changes in structure (poorly mineralized bone and enamel). If the pineal accumulates fluoride at an earlier age than in previous decades, one would anticipate that a high local concentration of fluoride within the pineal would affect the functions of the pineal, i.e., the synthesis of hormonal products, specifically melatonin... The controlled animal study carried out in this study produce compelling evidence that fluoride inhibits pineal melatonin output during pubertal development in the gerbil."

Fluoride & Pineal Gland - Earlier Puberty in Animals: (back to top)
"The section on the effects of fluoride on the physiological signs of sexual maturity in the gerbil was a preliminary, pilot study. There were not enough subjects to make any firm conclusions so an interpretation of the data is conjectural. However, the results do suggest that the HF (High-Fluoride) females had an accelerated onset of puberty as judged by several indices of pubertal development in rodents. At 7 weeks, the HF females were significantly heavier than the LF females (p < 0.004); as heavy as the HF males and LF males. The ventral gland in the HF female developed significantly earlier than in the LF female (p < 0.004). Vaginal opening occurred earlier in the HF female than in the LF female (p <0.03)."

Fluoride & Pineal Gland - Earlier Puberty in Humans? (back to top)
"The first step in assessing a health risk by a substance to humans is the identification of its harmful effects on animals. A health risk to humans is assessed using results from human epidemiological studies in conjunction with results from animal studies. The Newburgh-Kingston Study (Schlesinger et al, 1956) showed an earlier age of first menarche in girls living in the fluoridated Newburgh than in unfluoridated Kingston. The current animal study indicates that fluoride is associated with an earlier onset of puberty in female gerbils. Furthermore, more research was recommended on the effects of fluoride on animal and human reproduction (USPHS, 1991). This project has contributed new knowledge in this area."

Fluoride & Pineal Gland - Mechanism of Action: (back to top)
"The most plausible hypothesis for the observed significant decrease in the rate of urinary aMT6s excretion by the HF (High-Fluoride) group is that fluoride affects the pineal's ability to synthesize melatonin during pubertal development in the gerbil. Fluoride may affect the enzymatic conversion of tryptophan to melatonin. Although melatonin was the hormone investigated in this project, fluoride may also affect the synthesis of melatonin precursors, (e.g., serotonin), or other pineal products, (e.g., 5-methoxytryptamine). This would depend on the position(s) of the susceptible enzyme(s). For some unknown reason, pineal calcification starts intracellularly. Calcium has been demonstrated in pinealocyte mitochondria. Therefore, it may be a mitochondrial enzyme that is sensitive to the effects of fluoride, e.g., tryptophan-5-hydroxylase. Alternatively, fluoride may affect pinealocyte enzymes which require a divalent co-enzyme because such enzymes are particularly sensitive to fluoride."

Fluoride & Pineal Gland - Discussion: (back to top)
"Fluoride is now introduced at a much earlier stage of human development than ever before and consequently alters the normal fluoride-pharmacokinetics in infants.But can one dramatically increase the normal fluoride-intake to infants and get away with it? The safety of the use of fluorides ultimately rests on the assumption that the developing enamel organ is most sensitive to the toxic effects of fluoride. The results from this study suggest that the pinealocytes may be as susceptible to fluoride as the developing enamel organ. The possibility of a species difference between humans and gerbils does not allow the extrapolation of the gerbil data to humans. However, if increased plasma-fluoride levels cause a decline in the levels of circulating melatonin during early human development, significant physiological consequences may have already occurred. Changes in plasma melatonin concentrations are serious functional disturbances because melatonin has many functions in the organism. The pinealogists have not completely unravelled the mechanisms by which the pineal gland performs its tasks in the brain. The neurochemical phenomenon elicited by melatonin in CNS are unclear.
The first step in assessing a health risk by a substance to humans is the identification of its harmful effects on animals. A health risk to humans is assessed using results from human epidemiological studies in conjunction with results from animal studies. The Newburgh-Kingston Study (Schlesinger et al, 1956) showed an earlier age of first menarche in girls living in the fluoridated Newburgh than in unfluoridated Kingston. The current animal study indicates that fluoride is associated with an earlier onset of puberty in female gerbils. Furthermore, more research was recommended on the effects of fluoride on animal and human reproduction (USPHS, 1991). This project has contributed new knowledge in this area.
I do not intend to discuss the relative merits of the claims made by the anti-fluoridationists that chronic ingestion of low levels of fluoride has harmful effects on human health, i.e., increases the risk of cancer, affects the immune system, and hastens the aging process. These claims could be associated with the effects of fluoride on the pineal because the gland has been linked to oncogenesis, immunocompetence, and, in recent years, to the process of aging.In conclusion, the human pineal gland contains the highest concentration of fluoride in the body. Fluoride is associated with depressed pineal melatonin synthesis by prepubertal gerbils and an accelerated onset of sexual maturation in the female gerbil. The results strengthen the hypothesis that the pineal has a role in the timing of the onset of puberty. Whether or not fluoride interferes with pineal function in humans requires further investigation."
