Thread: How Dangerous Is Fluoride To Your Health?

  1. #31


    The following literature review by Peckham an Awofeso is not so positive about the health effects of fluoride– “Water Fluoridation: A Critical Review of the Physiological Effects of Ingested Fluoride as a Public Health Intervention” (2014):

    The United States' lead in instituting artificial water fluoridation led to its acceptance by the World Health Organization as an effective oral health intervention. At least 30 nations instituted artificial water fluoridation policies. However, a number of countries including Sweden, The Netherlands, Germany, and Switzerland stopped fluoridating their water supplies due to concerns about safety and effectiveness [8, 9]. Currently, only about 5% of the world's population—350 million people—(including 200 million Americans) consume artificially fluoridated water globally. Only eight countries—Malaysia, Australia, USA, New Zealand, Singapore, and Ireland, more than 50% of the water supply artificially fluoridate. Over the past two decades many communities in Canada, the USA, Australia, and New Zealand have stopped fluoridating their water supplies and in Israel the Minister for Health announced in April 2013 the end of mandatory water fluoridation. However, public health authorities continue to try and develop new community water fluoridation schemes.
    The inability to control individual dose renders the notion of an “optimum concentration” obsolete. In the USA, a study in Iowa found that 90% of 3-month-olds consumed over their recommended upper limits, with some babies ingesting over 6 mg of fluoride daily, above what the Environmental Protection Agency and the WHO say is safe to avoid crippling skeletal fluorosis [41]. Most recently a study in the UK of fluoride levels found in tea concluded that “… fluoride concentrations can exceed the recommended DRI of 4 mg/day…, in certain tea commodities, under the minimal brewing time of 2 min…” [42, page 569]. This study used nonfluoridated water but supports earlier findings by Koblar et al. who report that the adequate intake of fluoride from a 70 kg adult consuming five cups of tea daily ranges from 25 to 210% depending upon tea brand and whether the water is fluoridated [43].
    In a meta-analysis of 27 mostly China-based studies on fluoride and neurotoxicity, researchers from Harvard School of Public Health and China Medical University in Shenyang found strong indications that fluoride may adversely affect cognitive development in children [50]. All but one study suggested that high fluoride content in water may negatively affect cognitive development. The average loss in intelligence quotient (IQ) was reported as a standardized weighted mean difference of 0.45, which would be approximately equivalent to seven IQ points for commonly used IQ scores with a standard deviation of 15 [50]. While fluoride's effect on IQ in this meta-analysis did not reach statistical significance, the combined effect at population level is remarkable. A particular concern of the NRC committee was the impact of ingested fluoride on the thyroid gland [49]. In a 2005 study, it was found that 47% of children living in a New Delhi neighbourhood with average water fluoride level of 4.37 ppm have evidence of clinical hypothyroidism attributable to fluoride. They found borderline low FT3levels among all children exposed to fluoridated water [51].
    There are 66 enzymes which are affected by fluoride ingestion, including P450 oxidases, as well the enzyme which facilitates the formation of flexible enamel [65]. A recent study of the effects of inorganic fluoride compounds on human cellular functions revealed that fluoride can interact with a wide range of enzyme-mediated cellular processes and genes modulated by fluoride including those related to the stress response, metabolic enzymes, the cell cycle, cell-cell communications, and signal transduction [66]. Due to high negativity of fluoride, it interacts actively with positively charged ions such as calcium and magnesium. In industrial settings, hydrofluoric acid poisoning is usually treated with intravenous calcium gluconate as such poisoning is associated with acute hypocalcaemia [67]. As with calcium, magnesium plays important roles in optimal bone and teeth formation. By competing with magnesium and calcium in teeth and bones, fluoride deranges the delicate bone formation and bone resorption processes. Such derangements, and consequent intensity of fluoride's adverse effects on bone and teeth, are amplified in malnutrition, calcium deficiency, and magnesium deficiency [68, 69]. Chronic fluoride ingestion is commonly associated with hyperkalaemia and consequent ventricular fibrillation [70].

    First of all, I would dispute those numbers, however accepting them for the sake of argument, children are only children for about 15 years, and they only have their baby teeth for about 10 of those years. If 10% of human beings starting from scratch suffer from moderate to severe fluorosis over a 10 year period, then what about the adults who live for another 65 years and keep their same teeth the entire time?

    Default Diabetes, Alzheimer’s

    I had planned to make a good post on Fluoride a long time ago (I wanted to do this at the beginning of October 2017), but got tangled up in some other things…

    Fluoride is a highly toxic chemical waste from the production of aluminium (and other metals). Several Americans sued the aluminium industry for their damages (health problems) caused by Fluoride. So they invented practical ways to use Fluoride: rat poison, insecticide and Sarin gas.
    The (German) Nazis had experimented with Fluoride in the concentration camps to discover that their slave labourers became docile and it can be used for sterilisation. These days Fluoride is also used in psychiatric drugs (that cause psychiatric problems).

    In the 1950s it was discovered that Fluoride “prevents cavities in our teeth”. The research was really “independent”; financed by Aluminium Company of America (ALCOA), Aluminium Company of Canada, American Petroleum Institute, Dupont, Kaiser Aluminium, Reynolds Steel, US Steel and National Institute of Dental Research.
    In 1952 a massive advertisement campaign was started, to dump Fluoride in the American tap water and tooth paste:

    The Bush family is connected to ALCOA; see for example Paul O’Neil, who served as CEO for ALCOA before joining the George W. Bush administration:'Neill

    In the 1950's, USAF Major George R. Jordan testified that the Soviets openly admitted to "using the fluoride in the water supplies in their concentration camps, to make the prisoners stupid, docile, and subservient".

    The available studies show that in some people, fluoride exposure causes increases in blood glucose or impaired glucose tolerance and/or increases the severity of diabetes.
    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.
    Diabetic individuals will often drink more water than the average, so will have a higher than normal fluoride intake (at least in the US):

    Fluoride increases blood glucose levels and impair glucose tolerance, likely by inhibiting insulin production or secretion.
    Impaired glucose tolerance, often a precursor to type 2 diabetes, has been found to occur in humans with fluoride intakes of only 0.07-0.4 mg/kg/day. Fluoride intake can therefore exacerbate diabetes.

    Human and animal studies have found that excessive fluoride consumption leads to increased serum fluoride levels, with a concomitant increase in serum glucose levels.
    If the body is not able to regulate the amount of glucose in the blood, as occurs in diabetes mellitus, chronic elevated blood sugar (hyperglycemia) can lead to serious complications.
    This can cause damage to the kidneys, brain, nervous system, cardiovascular system, retina, legs and feet, etc.

    Studies on both animals and humans have shown that after fluoride ingestion more insulin is secreted, which can result in hyperglycemia.
    Fluoride may also lead to increased insulin resistance, or decreased insulin sensitivity, thus contributing to glucose intolerance:

    In a “scientific” report published in 2016, Fluegge used mathematical models to analyse publicly available data on fluoride water levels and diabetes incidence and prevalence rates across 22 states between 2005 and 2010.
    Two sets of regression analyses suggested that supplemental water fluoridation increases diabetes incidence.
    Fluegge reported that a one milligram increase in average county fluoride levels predicted a 0.17% increase in age-adjusted diabetes prevalence:

    Over 32 years, from 1980 to 2012, the number of adults with diagnosed diabetes in the US nearly quadrupled, from 5.5 million to 21.3 million. Among adults, about 1.7 million new cases of diabetes are diagnosed each year.
    If this trend continues, as many as one third of the US population could have diabetes by 2050.

    County-level data for the years 2005 and 2010 were collected, investigating if there is a correlation between diabetes incidence and fluoride in the drinking water.
    Fluoride added to achieve “optimal” levels (between 0.7–1.2 ppm) was significantly associated with increases in both the incidence and prevalence of diabetes.

    Adjusting for changes in physical inactivity, obesity, poverty, log population per square mile, mean number of years fluoridated and year, a 1 mg increase in the amount of added fluoride for an average county significantly increased the diabetes incidence by 0.23 per 1,000 as compared to a county without such an increase.
    For added fluoride, a 1 ppm increase produced a 0.35 per 1,000 increase in diabetes incidence and a 0.27% increase in prevalence.

    Among the 3 fluoridation chemicals used in this data set - sodium fluoride, fluorosilicic acid, or sodium fluorosilicate -, only sodium fluoride showed a significant and robust increase of diabetes.

    Alzheimer’s disease
    In 1965, 3 independent studies were published that linked aluminium with Alzheimer’s disease. Subsequently numerous international studies have found more Alzheimer’s disease in areas with high aluminium levels in drinking water.
    Normally metals from the body don’t reach the brain.

    In 2013, Akinrinade and his colleagues from Bingham University in Nigeria showed that fluoride makes aluminium reach the brain. Fluoride combines with aluminium to form aluminium fluoride. In the body it eventually combines with oxygen to form aluminium oxide or alumina.
    Aluminium oxide has been found in the brains of patients with Alzheimer’s disease:

    I’ve found another interesting article.

    The FDA has never approved fluoride drops and tablets as either safe or effective, even though fluoride drugs have been prescribed for over 50 years. In 2016, the FDA announced that marketing fluoride drops and tablets for cavity prevention violates federal law.
    On 13 January 2016, the FDA sent a warning letter to Kirkman Laboratories Inc., demanding the immediately cease of selling fluoride drops and tablets:
    The above products also are “prescription drugs” as defined in section 503(b)(1)(A) of the Act [21 U.S.C. § 353(b)(1)(A)], because, in light of their toxicity or potential for harmful effects, or the method of their use, or the collateral measures necessary for their use, they are not safe for use except under the supervision of a practitioner licensed by law to administer them.1

    Strangely, the 4 largest pharmacies in the US - Walgreens, CVS, Rite Aid, and Walmart - continue to sell unapproved fluoride drugs, in violation of the federal prohibition on introducing unapproved drugs and the laws of at least 17 stated which prohibit the "sale" of any drug not approved by the FDA:

    Fluoride advocates often claim that the reduction in tooth decay that has occurred since the 1950s is the result of the widespread use of fluoridated water.
    Despite rejecting fluoridated water, tooth decay Europe has declined at a similar speed as in the US. Tooth decay rates in Europe are generally lower than in heavily fluoridated US:

    Fluoride is a cause of magnesium deficiency. In our body, the negatively charged fluoride binds with positively charged magnesium, which causes magnesium deficiency.
    Ironically fluoride deficiency is also bad for our health...

    Fluoride can be fatal: for a 2-year-old 60 mg and for a 9-year-old 120 mg could kill.
    A tube of commercial toothpaste contains about 143 mg fluoride:

    An estimated 80% of Americans are magnesium deficient.
    Prescription drugs can also deplete your body of magnesium.
    Early signs of magnesium deficiency include loss of appetite, headache, nausea, fatigue, and weakness.
    Magnesium deficiency can cause amongst others: osteoporosis, heart attacks and diabetes.

    Over the past 30 years, women have been told to take supplemental calcium to avoid osteoporosis, and calcium has been added to food. Osteoporosis rates have continued to climb.

    You can’t simply add magnesium to your diet to solve problems, because when you take any of the following you need to take all the others into consideration as well: magnesium, calcium, vitamin D3, and vitamin K2.
    If you're K2 or magnesium deficient, adding calcium will cause more problems than it solves. Taking mega doses of vitamin D supplements without sufficient amounts of K2 and magnesium can lead to vitamin D toxicity and magnesium deficiency symptoms.

    If you have too much calcium and not enough magnesium, your muscles will tend to go into spasm. This could cause a heart attack:

    A total of 299 mother–child pairs had data on either GCI (at 4 years old) or IQ (at 6 years or older), and 199 mother–child pairs had data on both GCI and IQ.
    At age 4 year, neurocognitive outcomes (GCI) were measured using the McCarthy Scales of Children’s Abilities (MSCA).
    For children 6–12 year old, the Wechsler Abbreviated Scale of Intelligence (WASI) was administered (IQ).

    Figure 2, shows the (adjusted) correlation between urinary fluoride level (MUF) and General Cognitive Index (GCI) scores in children at age 4. You can see that averagely the children score lower with higher prenatal fluoride exposure.

    Figure 2, shows the (adjusted) correlation between urinary fluoride level (MUF) and IQ at age 6–12. It looks like only fluoride levels higher than 1 mg/l prenatal are associated with a lower IQ.

    Giving a magnesium deficient population added calcium - is poisoning us...
    This again proves that our medical industry is worse than quackery, as this is done intentionally.

    Teeth are alive, and it seems illogical that a toxic (like fluoride) would preserve them. Maybe the effect of fluoride is similar to a toxic like chloride in swimming pools, which keeps it looking clean and fresh…

His opinion was that the area of decay before its discovery was significantly greater than it would have been otherwise resulting in much larger fillings or more involved restorative procedures.

    Just one former dentist's opinion.
    Another effect of fluoride is that it destroys enzymes and bacteria. This effect is probably also bad for your teeth.

    It is known that osteoporosis (which is caused by ingesting fluoride) in turn causes teeth loss. So even if the fluoride prevents cavities, good teeth could still be lost because of fluoride...

    In the United States more than 53 million people either have osteoporosis or are at high risk due to low bone mass.
    Several studies have found, that when the jawbone is weakened by osteoporosis, this increases loose teeth and tooth loss. Women with osteoporosis have a 3 times higher chance to experience tooth loss (than those without the disease).
    Osteoporosis can also cause periodontitis, although the relationship with skeletal bone density is not clear. Research has shown that magnesium deficiency leads to periodontitis (see below)…
    Periodontitis is a chronic infection that affects the gums and bones that support the teeth. Teeth may eventually become loose, fall out, or have to be removed:

    Magnesium can counter and reduce the toxic effects of fluoride.
    Calcium and magnesium are important structural components of teeth and bone. Fluoride binds with magnesium and calcium – this is bad for our teeth…
    In a “scientific” study, subjects from 40 to 80 years old, with the highest calcium–to–magnesium ratio suffered greater tooth loss than those with a lower calcium–to–magnesium ratio.

    In 1941, Time Magazine published an article about the “perfect teeth” and low incidence of bone fracture among residents of Deaf Smith County, Texas.
    The water in Deaf Smith County had a magnesium content twice as high as that in Dallas County (where bone fracture and tooth decay were common). The water in Deaf Smith County also contained relatively much calcium and “natural” fluoride...
    Adverse effects of fluoride, like weakening of bones and brown stains and tooth pitting on teeth, were also absent in Deaf Smith County:
    Teeth just plain don't decay in Deaf Smith County, on the sandy plains of the Texas panhandle. (Elsewhere in the U.S. 95 out of 100 have dental caries.) This remarkable fact was reported last week to the Houston meeting of the American Dental Association by Dr. Edward Taylor, chief dentist of the Texas State Board of Health.
    In 1961, Nature reported about a significant reduction in dental caries in 200 patients that were given an alkaline phosphate (= magnesium) for 3 years. Scientists in New Zealand discovered that magnesium was the beneficial factor.
    They concluded that:
    an important role can possibly be assigned to magnesium [phosphate] in the stabilization of chemical, physical and electrokinetic states of the surface enamel calcium.
    In other words, calcium can only have a positive impact after it is stabilised, for example by magnesium.

    Studies on guinea pigs and rats have confirmed the importance of magnesium:
    When guinea pigs are fed a diet deficient in magnesium they grow slowly and, if they survive for a few months, they develop deposits of calcium phosphate in such organs as the kidneys, muscles, liver, stomach, and heart.
    A high calcium level in the diet increases the magnesium requirement of guinea pigs just as has been observed by others who have studied the magnesium requirement of the rat.
    When researchers at Loma Linda University in California substituted whole wheat with white flour in the food for rats, they found that more caries developed. Whole wheat flour contains 113 mg of magnesium per 100 grams, but white flour has only 25 mg.
    There were 3.64 carious lesions per rat on the white flour diet, which also contained the high calcium foods cottage cheese and milk.
    On the same diet, but with high magnesium whole wheat flour, there were only 1.16 carious lesions.

    Lewis B. Barnett in September 1966 stated that supplementing our diet with magnesium would be a much better method than fluoride for tooth decay prevention.

    Here’s the “short” story:
    Here’s the long version (which is part of a book on magnesium):
