Harvard Study Confirms Fluoride Reduces Children’s IQ
By Dr. Joseph Mercola


A recently-published Harvard University meta-analysis funded by the National Institutes of Health (NIH) has concluded that children who live in areas with highly fluoridated water have “significantly lower” IQ scores than those who live in low fluoride areas.

The Phosphate Fertilizer Industry: An Environmental Overview

1. Introduction

They call them “wet scrubbers” – the pollution control devices used by the phosphate industry to capture fluoride gases produced in the production of commercial fertilizer.

In the past, when the industry let these gases escape, vegetation became scorched, crops destroyed, and cattle crippled.

Today, with the development of sophisticated air-pollution control technology, less of the fluoride escapes into the atmosphere, and the type of pollution that threatened the survival of some communities in the 1950s and 60s, is but a thing of the past (at least in the US and other wealthy countries).

However, the impacts of the industry’s fluoride emissions are still being felt, although more subtly, by millions of people – people who, for the most part, do not live anywhere near a phosphate plant.

That’s because, after being captured in the scrubbers, the fluoride acid (hydrofluorosilicic acid), a classified hazardous waste, is barreled up and sold, unrefined, to communities across the country. Communities add hydrofluorosilicic acid to their water supplies as the primary fluoride chemical for water fluoridation.

Even if you don’t live in a community where fluoride is added to water, you’ll still be getting a dose of it through cereal, soda, juice, beer and any other processed food and drink manufactured with fluoridated water.

Meanwhile, if the phosphate industry has its way, it may soon be distributing another of its by-products to communities across the country. That waste product is radium, which may soon be added to a roadbed near you – if the EPA buckles and industry has its way.

"Today, the same gypsum stack which caused this particular spill, is considered by Florida’s Department of Environmental Protection to be “the most serious pollution threat in the state.” That’s because tropical rains over the past couple of years have brought the wastewater to the edge of the stack’s walls.

As noted by the Tampa Tribune, “The gypsum mound is near capacity, and a wet spring or a tropical storm could cause a catastrophic spill.”

To prevent such a spill, which was all but inevitable, the EPA recently agreed to let Florida pursue “Option Z“: To load 500-600 million gallons of the wastewater onto barges and dump it directly into the Gulf of Mexico.

The dumping of the wastewater into the Gulf represents the latest in a series of high-profile embarrasments for Florida’s phosphate industry; one of the most dramatic of which happened on June 15, 1994.

On that day, a massive, 15-story sinkhole appeared in the middle of an 80 million ton gypsum stack. The hole was so big that, according to US News & World Report, it

“could be as big as 2 million cubic feet, enough to swallow 400 railroad boxcars. Local wags call it Disney World’s newest attraction — ‘Journey to the Center of the Earth.'”

But, as US News noted,

“there’s nothing amusing about it. The cave-in dumped 4 million to 6 million cubic feet of toxic and radioactive gypsum and waste water into the Floridan aquifer, which provides 90 percent of the state’s drinking water.”"

RE: Drinking Water Fluoridation

March 1, 1998

Dear Supervisors,

I am David Kennedy, DDS. I am a preventive dentist. I have practiced dentistry in San Diego for more than 20 years. My father and grandfather before me were also dentists.

I served on the board of the San Diego Better Business Bureau for over 10 years, and have been a member of the Centre City Optimist Club for 20 years as well.

I have been a member of the San Diego County Dental Society for over 20 years, and for three years elected to the Board of Directors. I have participated on numerous committees including. Senior Care, Speakers Bureau, Political Action Committee, and the Council on Dental Care.

In 1974 Eddy Oriole and I planned and built the Chicano Children's Dental Health Clinic at 1809 National Avenue. I care about children's dental health.

I am immediate Past President of International Academy of Oral Medicine and Toxicology, the author of a book on preventive dental health entitled How to Save Your Teeth, and a nationally and internationally recognized lecturer on toxicology and restorative dentistry.

I am intensely interested in the welfare of my patients and the community at large.

Although I am a member of the San Diego County Dental Society (SDCDS), The California Dental Association (CDA) and the American Dental Association (ADA), I must begin my statement by expressing my opposition to these organization's stances concerning the safety of fluoride and further clarify what an endorsement by any of these organizations represents.

1) CDA and ADA perform no research of their own.

2) These trade associations have successfully argued in court that they assume no legal liability for any harm that may result from their recommendations.

3) Dental organizations are not responsible for studying adverse systemic effects of water fluoridation. These issues are appropriately studied by medical researchers, epidemiologists and toxicologists.

4) CDA and ADA have never provided their members any large scale blinded studies which prove that fluoridation reduces tooth decay. An expert for the ADA testified in court that she was not aware of any blinded animal or broad based blinded human epidemiological studies that has ever found a reduction in tooth decay from drinking water with one part per million fluoride.

5) CDA and ADA have never polled their membership for their knowledge or opinion of water fluoridation.

The two following examples clearly illustrate the depth and reliability of dentist's understanding of this controversial issue.

A) Despite the local dental society's recommendation of water fluoridation, my conversation with the President of the San Diego Dental Society, Dr. Joel Berick, revealed that he was completely unaware of even the existence of numerous studies linking water fluoridation to hip fracture.

B) An elderly dentist from Chula Vista took umbrage with my position opposing water fluoridation. He claimed that, over the last 50 years in his practice, he had personally witnessed the tremendous benefit of water fluoridation in Chula Vista. When I pointed out that Chula Vista was a nonfluoridated community, he appeared disoriented and mumbled, "It had to be the fluoride. Tooth decay is not nearly as prevalent as when I began to practice 50 years ago."

The above summary is not intended to criticize the dental society, but rather to place the dental trade organizations endorsements in their proper perspective.

Increasing the fluoride intake of a patient without regard to established risk factors such as age, kidney function, weight, physical condition, water consumption, total fluoride intake, and mitigating dietary calcium is medical negligence. Although the courts have ruled that the state has the power to do so under police powers. mandating fluoridation for 25 Million Californians or the entire city of Mountain View is no less negligent.

Dental Fluorosis

The first visible sign of this negligence will be a doubling in dental fluorosis. The cells that produce the collagen matrix, which forms enamel, are poisoned to the point that they can no longer produce opalescent pearl-like enamel. Fluorotic enamel is irregular in texture, porous, chalky white to brown in color, and brittle. In severe cases, the enamel forms incompletely and corners easily break off the teeth.

All of the organizations promoting water fluoridation agree that dental fluorosis, which is the first visible sign of systemic poisoning, increases with water fluoride levels. The Legislative Office of Budget Management acknowledges that drinking water fluoridation would increase disfiguring dental fluorosis, but since treatment of this disease is not covered for children on welfare, calculated that there would be no additional. cost to the state. Clearly they are not considering the enormous legal liability for physical and psychological damage which accompany this disfiguring disease.

The fact that the state will not spend money to correct this defect does not alter the basic truth that fluorosis will have to be treated if the child is to be happy in our image conscious society.

Let's be clear about what children will be adversely affected. Bottle fed babies are most likely to develop dental fluorosis. Mothers milk has virtually no fluoride present. Those children who are deficient in intake of protein, calcium, magnesium, phosphorous, and Vitamin C are especially vulnerable to fluoride poisoning. The accumulation of fluoride is greatly increased if the person has impaired kidney function. In short, the weakest members of our society, the undernourished, the underfed, the very children that fluoridation was to allegedly benefit. In some poorer communities as much as 80% of the children have fluorosis[1].

The correction of this permanent disfigurement involves crowns, laminates, bonding, and bleaching. The physical, psychological, emotional, and financial costs of the repeated trauma necessary to correct this condition far exceeds any projected benefit that fluoridation can possibly produce. This is truly a case where the treatment is worse than the problem.

The incidence of dental fluorosis has steadily increased since the introduction of fluoride to the drinking water in 1945. Since the introduction of fluoride containing toothpaste the amount of fluorosis has dramatically risen[2]. Fluoride tablets which deliver in prescription form the amount of fluoride alleged to be beneficial for tooth decay, reduction cause dental fluorosis in 64% of the children (Pebbles 1974). These same tablets if swallowed provide no protection against decay. If they are chewed and dissolved in the mouth, they do appear to reduce decay[3]. The effect is topical[4].

Hip Fracture

Fluoride has been tested on humans for the purpose of treating osteoporosis. The theory was that fluoride would strengthen bones. What the researchers found was that it did increase bone mass; however, the bone was much more brittle -- leading to a dramatic increase in hip fracture[5]. Numerous studies have linked long term consumption of fluoridated water to increased risk of hip fracture.[6]

This is not a small matter, it is about life and death. The surgical cost of repairing a hip fracture is $35,000. 25% of the victims die in the first 30 days. Only 11% of the victims ever return to independent living. 100% of the victims are debilitated and few, if any, of the elderly ever regain their former ability to walk normally. The research clearly shows that water Fluoridation increases the number of people who will suffer this devastating injury.

Nine of thirteen studies show a correlation between hip fracture and fluoridation, including four published in the Journal of the American Medical Association in the last five years. In matters as serious as the health of our nation, no risk is acceptable if it is avoidable.


Research has shown in numerous studies that fluoride is a mutagen (genetic damage), a carcinogen (cancer causing), and cancer promoting in laboratory cell studies, animals, and humans. In 1990 the Congress-ordered National Toxicological Program (NTP) found bone cancers in male rats.

The test animals, in the words of the board certified pathologists, "were awash with disease." T he high dose animals had kidney failure and cancers of their lips, cheeks, throats, livers, and bones. The highest rates of cancer were found in the highest dose animals. The lucky rats and mice that drank the distilled fluoride free water had no significant disease. When the actual data indicated a causal relationship between fluoride and bone cancer the NTP down-graded the results to "equivocal."

Dr. William Marcus, former senior science advisor at the office of drinking water Environmental Protection Agency (EPA), concluded that the NTP studies proved fluoride was a carcinogen[7]. In July 1997 the National Federation of Federal Employees. the Union representing all of the scientists, toxicologists and statisticians at EPA headquarters, also stated that "Our members review of the body of evidence over the last eleven years, including animal and human epidemiological studies, indicate a causal link between fluoride/fluoridation and cancer, genetic damage, neurological impairment, and bone pathology. Of particular concern are recent epidemiological studies linking fluoride exposure to lower 1.0. in children.[8]

Political protection for fluoride is not new. The Spin Doctors of fluoridation routinely minimize the peer-reviewed documented scientific research by setting up biased review committees, which then publish their own opinion claiming that fluoridation is safe, without regard to the original findings. The US Public Health Service has been accused of scientific fraud by the National Federation of Federal Employees over the cover-up of the cancer/fluoride link.

After the NJ Department of Health documented a dramatic increase in bone cancers in young men who resided in their fluoridated cities, New Jersey Assemblyman John V. Kelly asked the Food and Drug Administration (FDA) for the evidence they relied upon in approving prescription fluoride drops and tablets.

The FDA responded that no application for approval, or studies of safety or effectiveness, had ever been submitted and that they were not in possession of any such evidence. Ask yourself for another example of a prescription drug on the United States market (30 plus years) for which no FDA Application has ever been submitted.

When pressured as to why he did not remove the drops and tablets from the market Frank R. Fazzari, Chief of Prescription Drug Compliance reportedly expressed concern for his position and recommended Assemblyman Kelly sue him in order to have a Federal Judge make him comply with congressional law.

The new Food and Drug required warning should provide some clarification as to the safety of fluoride. The FDA now requires all toothpaste containing fluoride to have the following warning attached, "WARNING: Keep out of reach of children under 6 years of age. In case of accidental ingestion, seek professional assistance or contact a Poison Control Center immediately." The amount to be used in brushing is a pea sized amount or about 1 milligram. One liter of water in a fluoridated community will contain one milligram.

Tooth Decay Costs Savings

All of the recent large scale studies have found no relationship to tooth decay and water fluoride levels. Earlier studies that are often cited by fluoridation promoters are transparently flawed. The examiners were not standardized or blinded. There are no randomized controlled blinded studies of animals or humans that have ever found a reduction in decay from ingesting fluoride. On the contrary, all of the recent large-scale studies have failed to show any significant reduction.

Studies of fluoride have confirmed that the effect it has on tooth decay reduction is not systemic. The effect is not produced by swallowing the toxic substance, but is in fact a topical effect upon the bacteria that live in the mouth and cause tooth decay. It poisons them. The design of the experiment leaves little doubt -as to the results. Cavity-prone rats were given fluoride in two ways. One group got fluoride in the mouth from a time release tablet bonded to the outer surface of the tooth. The other group got the same amount administered in a slow pump under the skin. The oral dose of fluoride produced some reduction in decay over controls, but the systemic exposure did not reduce tooth decay at all. However, the poisonous nature of fluoride does not change when ingested.

Animals fed sugar-water and fluoride fare no better in terms of tooth decay than animals fed sugar-water alone. Human tooth decay is linked to diet, sugar intake, tooth brushing technique, hours of sunlight, parental education, and family income. These variables must be considered in order to produce accurate results.

In the largest study of tooth decay in America, there was no significant difference in the decay rates of 39,000 fluoridated, partially fluoridated, and non fluoridated children, ages 5 to 17, surveyed in that 84 city study. The decayed missing or filled rate in non-fluoridated Los Angeles was not significantly different than fluoridated San Francisco. In fact, the lowest decay rate was found in non-fluoridated Buhler, KS.

Comparing the State of California 1994 non-weighted dental costs for the 14 largest counties reveals that counties 90% fluoridated spent on average $121.93 per eligible recipient for treatment of tooth decay, and counties with less than 10% fluoridation spent only $118.33 per eligible recipient.

Weighted 1995 California per Eligible Welfare Recipient Dental Costs
CA Counties 90 -100 % Fluoridated $125.27
CA Counties 0.5- 10% Fluoridated $107.26

With less than 17% of the state fluoridated, California children have fewer cavities than the nation as a whole. Where is the alleged proof of safety and effectiveness? Why are the costs of dental care higher in fluoridated areas?

This public health fraud will result only in increased misery-- kidney disease, hip fractures, cancers and even death to its many unfortunate victims. Not only will fluoridation not reduce the dental care costs, it will exponentially increase the fluorotic damage to underprivileged children.

National Research Council’s findings:

NRC’s Findings

The National Research Council’s report concluded that EPA’s safe drinking water standard (4 ppm) for fluoride is unsafe and “should be lowered.” The NRC based this conclusion on its finding that EPA’s 4 ppm standard places a person at increased risk for both tooth damage (severe dental fluorosis) and bone damage (bone fracture). While most of the press coverage of the NRC report focused on NRC’s concerns with teeth and bone, there are many other serious concerns expressed in the NRC report. As evident in the following excerpts, the NRC report lends credence to fluoride’s ability to affect a wide range of systems in the body, particularly the brain and endocrine system. These concerns are further amplified in the NRC’s research recommendations.


To read the NRC’s complete discussion of fluoride’s effect on the brain, click here.

“On the basis of information largely derived from histological, chemical, and molecular studies, it is apparent that fluorides have the ability to interfere with the functions of the brain and the body by direct and indirect means.” p.222

“A few epidemiologic studies of Chinese populations have reported IQ deficits in children exposed to fluoride at 2.5 to 4 mg/L in drinking water. Although the studies lacked sufficient detail for the committee to fully assess their quality and relevance to U.S. populations, the consistency of the results appears significant enough to warrant additional research on the effects of fluoride on intelligence.” p.8

“histopathological changes similar to those traditionally associated with Alzheimer’s disease in people have been seen in rats chronically exposed to AlF.” p.212

“Fluorides also increase the production of free radicals in the brain through several different biological pathways. These changes have a bearing on the possibility that fluorides act to increase the risk of developing Alzheimer’s disease.” p.222

“More research is needed to clarify fluoride’s biochemical effects on the brain.” p.222

“The possibility has been raised by the studies conducted in China that fluoride can lower intellectual abilities. Thus, studies of populations exposed to different concentrations of fluoride in drinking water should include measurements of reasoning ability, problem solving, IQ, and short- and long-term memory.” p.223

“Studies of populations exposed to different concentrations of fluoride should be undertaken to evaluate neurochemical changes that may be associated with dementia. Consideration should be given to assessing effects from chronic exposure, effects that might be delayed or occur late-in-life, and individual susceptibility.” p.223

“Additional animal studies designed to evaluate reasoning are needed.” p.223


“In summary, evidence of several types indicates that fluoride affects normal endocrine function or response; the effects of the fluoride-induced changes vary in degree and kind in different individuals. Fluoride is therefore an endocrine disruptor in the broad sense of altering normal endocrine function or response, although probably not in the sense of mimicking a normal hormone. The mechanisms of action remain to be worked out and appear to include both direct and indirect mechanisms, for example, direct stimulation or inhibition of hormone secretion by interference with second messenger function, indirect stimulation or inhibition of hormone secretion by effects on things such as calcium balance, and inhibition of peripheral enzymes that are necessary for activation of the normal hormone.” p.266

“Some of these [endocrine] effects are associated with fluoride intake that is achievable at fluoride concentrations in drinking water of 4 mg/L or less, especially for young children or for individuals with high water intake. Many of the effects could be considered subclinical effects, meaning that they are not adverse health effects. However, recent work on borderline hormonal imbalances and endocrine-disrupting chemicals indicated that adverse health effects, or increased risks for developing adverse effects, might be associated with seemingly mild imbalances or perturbations in hormone concentrations. Further research is needed to explore these possibilities.” p.8

“Further effort is necessary to characterize the direct and indirect mechanisms of fluoride’s action on the endocrine system and the factors that determine the response, if any, in a given individual.” p.266

“The effects of fluoride on various aspects of endocrine function should be examined further, particularly with respect to a possible role in the development of several diseases or mental states in the United States.” p.267


To read the NRC’s complete discussion of fluoride’s effect on the thyroid, click here.

“several lines of information indicate an effect of fluoride exposure on thyroid function.” p.234

“it is difficult to predict exactly what effects on thyroid function are likely at what concentration of fluoride exposure and under what circumstances.” p.234-5

“Fluoride exposure in humans is associated with elevated TSH concentrations, increased goiter prevalence, and altered T4 and T3 concentrations; similar effects on T4 and T3 are reported in experimental animals..” p.262

“In humans, effects on thyroid function were associated with fluoride exposures of 0.05-0.13 mg/kg/day when iodine intake was adequate and 0.01-0.03 mg/kg/day when iodine intake was inadequate.” p.262-3

“The recent decline in iodine intake in the United States (CDC 2002d; Larsen et al. 2002) could contribute to increased toxicity of fluoride for some individuals.” p.263

“Intake of nutrients such as calcium and iodine often is not reported in studies of fluoride effects. The effects of fluoride on thyroid function, for instance, might depend on whether iodine intake is low, adequate, or high, or whether dietary selenium is adequate.” p.265


“The single animal study of pineal function indicates that fluoride exposure results in altered melatonin production and altered timing of sexual maturity (Table 8-1). 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.” p.264


“The conclusion from the available studies is that sufficient fluoride exposure appears to bring about increases in blood glucose or impaired glucose tolerance in some individuals and to increase the severity of some types of diabetes. In general, impaired glucose metabolism appears to be associated with serum or plasma fluoride concentrations of about 0.1 mg/L or greater in both animals and humans. In addition, diabetic individuals will often have higher than normal water intake, and consequently, will have higher than normal fluoride intake for a given concentration of fluoride in drinking water. An estimated 16-20 million people in the U.S. have diabetes mellitus; therefore, any role of fluoride exposure in the development of impaired glucose metabolism or diabetes is potentially significant.” p.260


“Nevertheless, patients who live in either an artificially fluoridated community or a community where the drinking water naturally contains fluoride at 4 mg/L have all accumulated fluoride in their skeletal systems and potentially have very high fluoride concentrations in their bones. The bone marrow is where immune cells develop and that could affect humoral immunity and the production of antibodies to foreign chemicals.” p.293-4

“There is no question that fluoride can affect the cells involved in providing immune responses. The question is what proportion, if any, of the population consuming drinking water containing fluoride at 4.0 mg/L on a regular basis will have their immune systems compromised? Not a single epidemiologic study has investigated whether fluoride in the drinking water at 4 mg/L is associated with changes in immune function. Nor has any study examined whether a person with an immunodeficiency disease can tolerate fluoride ingestion from drinking water.” p.295

“bone concentrates fluoride and the blood-borne progenitors could be exposed to exceptionally high fluoride concentrations. Thus, more research needs to be carried out before one can state that drinking water containing fluoride at 4 mg/L has no effect on the immune system.” p.295

“it is important to consider subpopulations that accumulate large concentrations of fluoride in their bones (e.g., renal patients). When bone turnover occurs, the potential exists for immune system cells and stem cells to be exposed to concentrations of fluoride in the interstitial fluids of bone that are higher than would be found in serum. From an immunologic standpoint, individuals who are immunocompromised (e.g., AIDS, transplant, and bone-marrow-replacement patients) could be at greater risk of the immunologic effects of fluoride.” p.302

“Within 250 µm of a site of resorption, it is possible to encounter progenitor cells that give rise to bone, blood, and fat. Thus, one must assume that these cells would be exposed to high concentrations of fluoride. At this time, it is not possible to predict what effect this exposure would have on the functioning of skeletal elements, hematopoiesis, and adipose formation.” p.142

“It is paramount that careful biochemical studies be conducted to determine what fluoride concentrations occur in the bone and surrounding interstitial fluids from exposure to fluoride in drinking water at up to 4 mg/L, because bone marrow is the source of the progenitors that produce the immune system cells.” p.303

“In addition, studies could be conducted to determine what percentage of immunocompromised subjects have adverse reactions when exposed to fluoride in the range of 1-4 mg/L in drinking water.” p.303


“Intake of nutrients such as calcium and iodine often is not reported in studies of fluoride effects. The effects of fluoride on thyroid function, for instance, might depend on whether iodine intake is low, adequate, or high, or whether dietary selenium is adequate.” p.265

“Better characterization of exposure to fluoride is needed in epidemiology studies investigating potential effects. Important exposure aspects of such studies would include the following: collecting data on general dietary status and dietary factors that could influence exposure or effects, such as calcium, iodine, and aluminum intakes.” p.88

“Available information now indicates a role for aluminum in the interaction of fluoride on the second messenger system; thus, differences in aluminum exposure might explain some of the differences in response to fluoride exposures among individuals and populations.” p.265

“With the increasing prevalence of acid rain, metal ions such as aluminum become more soluble and enter our day-to-day environment; the opportunity for bioactive forms of AlF to exist has increased in the past 100 years. Human exposure to aluminofluorides can occur when a person ingests both a fluoride source (e.g., fluoride in drinking water) and an aluminum source; sources of human exposure to aluminum include drinking water, tea, food residues, infant formula, aluminum-containing antacids or medications, deodorants, cosmetics, and glassware.” p.51

“Further research should include characterization of both the exposure conditions and the physiological conditions (for fluoride and for aluminum or beryllium) under which aluminofluoride and beryllofluoride complexes can be expected to occur in humans as well as the biological effects that could result.” p.52

“Another possible explanation for increased blood lead concentrations which has not been examined is the effect of fluoride intake on calcium metabolism; a review by Goyer (1995) indicates that higher blood and tissue concentrations of lead occur when the diet is low in calcium. Increased fluoride exposure appears to increase the dietary requirement for calcium (see Chapter 8); in addition, the substitution of tap-water based beverages (e.g., soft drinks or reconstituted juices) for dairy products would result in both increased fluoride intake and decreased calcium intake.” p.52

“[G]iven the expected presence of fluoride ion (from any fluoridation source) and silica (native to the water) in any fluoridated tap water, it would be useful to examine what happens when that tap water is used to make acidic beverages or products (commercially or in homes), especially fruit juice from concentrate, tea, and soft drinks. Although neither Urbansky (2002) nor Morris (2004) discusses such beverages, both indicate that at pH < 5, SiF6 2- would be present, so it seems reasonable to expect that some SiF6 2- would be present in acidic beverages but not in the tap water used to prepare the beverages. Consumption rates of these beverages are high for many people, and therefore the possibility of biological effects of SiF62-, as opposed to free fluoride ion, should be examined.” p.53


“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, but design limitations make those studies insufficient for risk evaluation.” p.8

“the relationship between fertility and fluoride requires additional study.” p.193


“The possible association of cytogenetic effects with fluoride exposure suggests that Down’s syndrome is a biologically plausible outcome of exposure.” p.197

“A reanalysis of data on Down’s syndrome and fluoride by Takahashi (1998) suggested a possible association in children born to young mothers. A case-control study of the incidence of Down’s syndrome in young women and fluoride exposure would be useful for addressing that issue. However, it may be particularly difficult to study the incidence of Down’s syndrome today given increased fetal genetic testing and concerns with confidentiality.” p.204


“The numerous fluoridation studies in the past failed to rigorously test for changes in GI symptoms and there are no studies on drinking water containing fluoride at 4 mg/L in which GI symptoms were carefully documented.” p.269

“GI effects appear to have been rarely evaluated in the fluoride supplement studies that followed the early ones in the 1950s and 1960s.” p.274

“The table suggests that fluoride at 4 mg/L in the drinking water results in approximately 1% of the population experiencing GI symptoms.” p.274

“Whether fluoride activates G proteins in the gut epithelium at very low doses (e.g., from fluoridated water at 4.0 mg/L) and has significant effects on the gut cell chemistry must be examined in biochemical studies.” p.280

“There are a few case reports of GI upset in subjects exposed to drinking water fluoridated at 1 mg/L. Those effects were observed in only a small number of cases, which suggest hypersensitivity. However, the available data are not robust enough to determine whether that is the case.” p.295

“Studies are needed to evaluate gastric responses to fluoride from natural sources at concentrations up to 4 mg/L and from artificial sources.” p.302


“It is possible that a lifetime ingestion of 5-10 mg/day from drinking water containing 4 mg/L might turn out to have long-term effects on the liver, and this should be investigated in future epidemiologic studies.” p.293

“The effect of low doses of fluoride on kidney and liver enzyme functions in humans needs to be carefully documented in communities exposed to different concentrations of fluoride in drinking water.” p.303


“Human kidneys… concentrate fluoride as much as 50-fold from plasma to urine. Portions of the renal system may therefore be at higher risk of fluoride toxicity than most soft tissues.” p.280

“Early water fluoridation studies did not carefully assess changes in renal function.” p.280

“Fluoride appears to have the potential to initiate or promote cancers, particularly of the bone, but the evidence to date is tentative and mixed (Tables 10-4 and 10-5). As noted above, osteosarcoma is of particular concern as a potential effect of fluoride because of (1) fluoride deposition in bone, (2) the mitogenic effect of fluoride on bone cells, (3) animal results described above, and (4) pre-1993 publication of some positive, as well as negative, epidemiologic reports on associations of fluoride exposure with osteosarcoma risk.“ p.336

“Because fluoride stimulates osteoblast proliferation, there is a theoretical risk that it might induce a malignant change in the expanding cell population. This has raised concerns that fluoride exposure might be an independent risk factor for new osteosarcomas.” p.134

“Osteosarcoma presents the greatest a priori plausibility as a potential cancer target site because of fluoride’s deposition in bone, the NTP animal study findings of borderline increased osteosarcomas in male rats, and the known mitogenic effect of fluoride on bone cells in culture (see Chapter 5). Principles of cell biology indicate that stimuli for rapid cell division increase the risks for some of the dividing cells to become malignant, either by inducing random transforming events or by unmasking malignant cells that previously were in nondividing states.” p.322

Fluoride Deception

Civilized, sane, countries that ban or reject flouride

""The U.S. Environmental Protection Agency recommends that 1 part per million (ppm) of fluoride ions is acceptable in drinking water, but above 2 ppm is considered a serious health risk," said Sourav Saha, an assistant professor in FSU's Department of Chemistry and Biochemistry and its Integrative NanoScience Institute. "Because fluoride is carcinogenic even at such small doses, a sensor is needed to detect fluoride selectively at very low concentrations and in the presence of other naturally occurring and biologically important ions.""

In other words "acceptable" levels of fluoride only half poison the people who drink it.

"Fluoride Content of Various Processed Beverages
The mass fluoridation of water supplies thus results in the mass fluoridation of processed drinks and foods and drinks."

"Does Facebook Support Terror?

By Meira Svirsky Tuesday, July 18, 2017

In a move that has become unfortunately typical of Facebook, the social media giant has shut the page of the Counter Jihad Coalition, a group that educates the public on political Islam and exposes the human rights abuses inherent in sharia law.

When the notification came that the group had violated the company’s “Community Standards,” they were told that the page would be taken down for just 24 hours. One week later, the page remains closed.

Facebook also recently restricted and then shut down the public pages of Ex-Muslim of North America and Atheist Republic, groups that both provide support to those who leave Islam and often face persecution because of it.

While Islamists most likely mobilized to get the pages shut down by getting their followers to “flag” pages for violation, it is ultimately up to Facebook to check the claims and make the decision.

Meaning, the buck stops with Facebook.

These moves have not been made in a vacuum. Just recently, a high-level executive at Facebook met with the interior minister of Pakistan over the Islamist country’s demands to get “blasphemous” content off the platform.

Pakistan was pleased with the results of the meeting.

Tests have been conducted, for example, to see if Facebook is wielding its enormous power in the cyber world to simply flag what they deem hate speech or a promote a political agenda.

Unfortunately, based on results of experiments, for example, where identical content that demonized Palestinians versus Israelis, we saw that (after it was flagged) Facebook only shut down the anti-Muslim pages but allowed site promoting vile slander against Israel to remain posted.

And despite the fact that the Facebook claims to block content that violates their “community standards,” a case was filed by 20,000 Israelis charging that Facebook allows Palestinian terrorists to incite violent attacks against Israelis and Jews.

Facebook can rightly claim that, as a private company, they are not subject to America’s laws which guarantee freedom of speech – laws which, not incidentally, also protect the right to engage in hate speech (with the exception of incitement to immediate violence).

Ideally, those with a political outlook who are being shut down by Facebook should form an alternative social media platform.

However, Facebook should not be fooled into thinking that they are “doing good in the world” by siding with Islamists who use the politically constructed cry of Islamophobia to further their goal of a worldwide implementation of sharia law.

Moreover, as it has been unequivocally demonstrated, Islamist ideology is almost always a precursor to its violent manifestation.

By shutting down the voices that challenge both the violent and non-violent displays of political Islam, Facebook is de facto supporting terrorism – which certainly goes against its “community standards.”

"Spend a Summer of Jihad With Hamas

By Meira Svirsky Wednesday, July 12, 2017

Close to 120,000 Palestinian children will attend camps this summer run by Hamas, which gained control of the Gaza Strip 10 years ago, reported Breitbart, citing figures from the terrorist organization. In addition, tens of thousands more will participate in other camps run by jihadi groups.

The children will receive weapons and military training – including live shooting exercises — in addition to indoctrination against Jews and Israelis.

As in previous years, graduation ceremonies where the children show off their “skills” will be held in front of Hamas officials.

Openly stating their goals to train the next generation of militants, Usama Almuzeyni, a Hamas official, said, “The movement strives, through the summer camps, to train an entire generation to work for the liberation of Palestine.”

The theme of this year’s camps is “To Jerusalem We Come.” Almuzeyni said this was “to make it clear that Hamas faces one direction, and that is Jerusalem and occupied Palestine.”

Meanwhile, a recently-released U.N. report noted that under Hamas’ leadership, the Gaza Strip has become unliveable for its two-million residents — between lack of healthcare, education, electricity and fresh water and declining incomes, reported Reuters.

“Across the board we’re watching de-development in slow motion,” said Robert Piper, a U.N. coordinator for humanitarian aid and development activities in Gaza."
Islam - General / Was Muhammad Visited by the Angel Gabriel?
« Last post by PeteWaldo on July 16, 2017, 10:11:03 AM »
Since Muhammad himself believed it was a demon, it's a cinch he didn't come up with that idea on his own. I thought it was his wife Khadijah who came up with the suggestion, but apparently through Waraqa bin Naufal, the occult Ebionite Priest who came up with the idea.
Ran across a couple of sites in a quick search. Didn't read them through.

"What has happened to me? I am afraid for myself! However, Khadija and on the advice of lbn Neafal her cousin managed to convince Muhammad that the spirit was Gabriel. But the spirit did not introduce itself as the angel Gabriel."
