Fluoride - Demand AARP Take Action

“The evidence that fluoride is more harmful than beneficial is now overwhelming… fluoride may be destroying our bones, our teeth, and our overall health.” - Dr. Hardy Limeback,  former President of Canadian ADA, Head of Preventive Dentistry at Univ of Toronto, 2006 National Research Council Scientist (2007)

 

The 2006 National Research Council on Fluoride in Drinking Water commented to the EPA that fluoridation at 1 ppm can be anticipated to be harmful for those with reduced renal function and the elderly. The NRC confirmed that fluoride not excreted by kidneys builds up in bones, resulting in arthritic pain and increased brittleness. However, there were no EPA studies on the whole health impacts of fluoridated water on susceptible population such as kidney patients, children, those with prolonged disease or the elderly. There still aren’t. 

 

However, there is mounting science from other sources that “optimally fluoridated” water, which is known to cause varying degrees of dental fluorosis in 58% of Black American adolescents and 36% of White American adolescents, is causing subtle deficits in ability to remember or focus. That same “optimal level” has also been proved in a 2014 study as being nephrotoxic in rats with chronic kidney disease. Chronic kidney disease (CKD) affects approximately 15% of Americans, although CKD is quadruple the rate in Black Americans, and predictably worse in older Americans. 

 

Perhaps the most horrifying part of the story of fluoridation is that not only is at least 50% of every drop of fluoride that has passed the lips of a Baby Boomer permanently stored in bones, fluoride isn't the only poison in packages of fluoride that originate as the waste product of aluminum an phosphate industry. 100% of the fluoride sampled in a 2014 study was contaminated with aluminum; arsenic and lead were other common contaminants. In other words, fluoridated water serves as a delivery system for aluminum and lead into our bones and our brains. As we all know, aluminum is associated with Alzheimers in adults, and lead is associated with learning disabilities in children. Approximately 15% of the population who is sensitive to chemicals cite inability to think clearly and overwhelming fatigue as symptoms of exposure to fluoridated water. 

 

Our generation was part of a great human experiment. It may have had noble intentions based on the faulty hypothesis that  drinking fluoridated water prevented cavities. It is now known that any perceived benefits of fluoride are from tooth brushing.  Our grandchildren are the third generation in this travesty. I suggest we all DEMAND the AARP stand up for us and our grandchildren by issuing a strong position paper calling for the cessation of water fluoridation.

Here are three Oct 2014 news articles on the content of the Freedom of Information Act documents. Rev. Andrew Young, former UN ambassador has pursued them with the CDC, but to little effect. Civil Rights leaders have been calling for an end to community water fluoridation (CWF) since 2011. 

 

2015 LEGAL ARGUMENT (GROSS DISPROPORTIONALITY) 

There is a legal initiative in Peel, Ontario (pop 1.3m) to remove fluoride from the water supply based on the principle of gross disproportionality, i.e. marginal benefit does not justify great risk of harm. There is also a political effort afoot in Canadian govt to mandate fluoridation and thereby make the legal argument moot. I suggest this document is well-worth printing.  http://fluoridealert.org/wp-content/uploads/peel.june2014.pdf

  • b. Starting on page 20 is a devastating affidavit by Dr. Kathleen Thiessen, NAS/NRC scientist and international expert in risk assessment. Very readable summary of science indicating harm to populations in “optimally” fluoridated communities.

"The National Toxicology Program on Wednesday released a draft report linking prenatal and childhood fluoride exposure to reduced IQ in children, after public health officials tried for almost a year to block its publication."Brenda Balletti, PhD, March 16, 2023 

 

“The only reason we were able to get Kumar’s emails is because he’s a government official who is subject to Freedom of Information requests. It raises the question of what else we would learn if the emails of private actors, like the PR strategists who Kumar works with, were also accessible.” - Michael Connett, J.D. in  "Researchers Hid Data Showing Fluoride Lowers Kids’ IQs, Emails Reveal” by Brenda Baletti, Ph.D. (May 30. 2023)

 

It took long enough, what with the political machinations of bad actors, but the final phase of the lawsuit brought by the Food & Water Watch et al. v. EPA for its failure to adhere to the regulations of the Toxic Substances Control Act (TSCA) specific to the evidence of developmental neurotoxicity when exposure is pre- or post-natal even in low doses consistent with 'optimally' fluoridated city water will be heard (barring a government shutdown) between Jan 31-Feb 14, 2024. This is a historic trial because it is the first time that the EPA has been brought to task for failure to protect 'susceptible sub-populations' like infants under TSCA.

 

As previously noted in this thread, the brain damage to infants resulting in cognitive-behavioral deficits like more learning disabilities, lower IQ and behavioral problems is also noted in adults who have consumed fluoridated water for decades, resulting in dementia and other neuro-degenerative conditions. 

 

Additionally, kidney disease, arthritis, degenerative disc disease, brittle bones, etc. are caused by or exasperated by fluoridated water and foods prepared with that water. 

 

However, this month's "Fluoride on Trial" is only looking at the very high quality evidence of brain damage in the very young. For a preview of what is going on, see:

Your brain doesn’t need fluoride. Your thyroid gland doesn’t need fluoride. Your bones don’t need fluoride. The only part of your body that may benefit from fluoride are your teeth. And you can get the fluoride to your teeth through a very simple, elegant mechanism. You put it in toothpaste, you brush it on and you spit it out.” - Michael Connett, J.D., partner at Waters Kraus & Paul (2024) 

 

 “The controversy about fluoridation was inevitable because fluoridation was, in a real sense, conceived in sin. Fluoride is a major waste product of industry and one of the most devastating pollutants of the aluminum industry. The government not only dismissed the danger and left industry free to pollute, but it has promoted the intentional addition of fluoride - most of which is recycled industrial waste - to the nation’s drinking water.” - Prof. Albert Schatz  (1995)

 

If you or anyone in your family have thyroid or kidney disease, bone spursspondylosis, arthritis or any other bone disease watch this documentary. If you or anyone in your family has cataracts, learning disabilities or a degenerative neurological disease like dementia, watch this documentary. 

 

They knew in the 1940s and 1950s that fluoride caused a range of disease, and they know today. Fluoridation stakeholders who included some criminal medical and legal actors promoted it then, and similarly compromised players promote fluoridation now and for the same reason - it is profitable. Power, prestige and paychecks hinge on fluoridation policy.

NTP Scientific Director Tells The Defender What He Couldn’t Tell the Court

EPA Paid Expert Witness $137,000 to Testify in Landmark Fluoride Trial

Fluoride Expert Squares Off Against EPA on Day 1 of Landmark Trial

 

My goodness! It has been an exciting ride. The witness testimony in the #FluorideTrial has ended, but closing arguments will be heard on Tuesday 2/20/2024. 

 

Plaintiff witnesses were wonderful, and were not shaken by EPA Counsel. The Defense witnesses were another matter. 

 

Not only did David Savitz clearly and several times state that neither he nor the NASEM committee he chaired to review the 2019-200 early drafts of the NTP report dispute the NTP conclusions or fault the NTP methods, he articulated that the NASEM group only felt the communication should have been clearer. Right there, that's a big win. But there is more. Savitz: 

  • Admitted he knows little about fluoride science and hadn't read that much
  • Misrepresented the findings of several studies (called out on cross examination as wrong)
  • Claimed there is no sex difference associated with neurotoxins which makes him question those studies (cross examination pointed to toxicology texts confirming sex differences are common; Savitz excused his error by saying he hadn't read them because he is not a toxicologist)
  • Admitted that he pulls in big bucks as an "expert" - including for the Telecom Industry which he repeatedly brought up. His rate is $500 hr and he has earned well over $100k in this trial
  • Recently sat on a panel for Health Canada concerning fluoridation policy with two other paid fluoridation shills. Health Canada apparently had no problems with the obvious conflict of interests 
  • Received multimillion dollar grants from pro-fluoridation sources like NIDCR. 

 

Then there was the officious Brian Barone of the EPA who bored us all to tears with his complicated descriptions of processes. His primary job seems to have been to confuse the judge with meaningless drivel. Barone claimed he: 

 

  • Can't do a scientifically justifiable risk assessment because of all the uncertainty
  • Believes there is "something there" (a neurotoxic effect), but won't determine what it is until there is more precise science for him to begin his calculations
  • Pulled a  couple of "Bill Clintons" when he claimed "Health Protective" can mean different things and retorted to Plaintiff Counsel "depends on how you define 'plausible'" in his defense of a bizarre study that contrary to every other study found that boys drinking fluoridated water have 21 point higher IQs  
  • Judges that the NTP and all the other scientists did things wrong, that as the EPA "Director of Integrity" only he knows the right way to do science
  • Attributes levels of fluoride in the urine of 3rd trimester women living in fluoridated communities as probably largely due to their kidneys being oversaturated with fluoride and therefor unable to process it appropriately. 

 

When Plaintiff Counsel asked Barone if he was "comfortable" with the kidneys of pregnant women being oversaturated with fluoride, Barone gulped and said, "My comfort level is not germane to the issue.

 

Really!!!!! 

 

Liars, sociopaths and criminals! All of them. 

 

Judge Chen is reviewing taped deposition testimony on that bizarre outlier study prior to asking a few more questions of counsel and hearing closing arguments scheduled on Tuesday, Feb 20th. It'll take a couple of weeks to get a ruling, and then there is always the option of appeal. Stay tuned.

 Dr. Joel Bohemier’s presentation to the Commissioners of Collier County, FL  includes quotes for EPA, CDC and others under oath from TSCA trial depositions. This presentation was part of the Commissioners deliberation that resulted in its unanimous vote to end fluoridation last week: https://unite.live/widgets/4142/recording/player#  

 

It is in the hands of Judge Chen, now, but I've got to say that the closing on Feb. 20th was odd.

 

Not only did Judge Chen pepper both attorneys with questions, the EPA attorneys seemed to admit that fluoride exposure at doses consistent with water concentration of 1.5 ppm, 2 ppm and 4 ppm had been proven to result in lower IQ per studies of mom-child pairs performed in Canadian and other communities across the world. They admitted this despite the official policy of the U.S. EPA stating there is no harm up to 4 ppm (the actionable threshold for remediation) other than mild cosmetic dental fluorosis (tooth staining) at or above 2 ppm. The Canadian government has an actionable threshold of 1.5 ppm which is consistent with the WHO guidelines. 

 

When Judge Chen challenged the EPA that per both plaintiff and defense witnesses, shouldn't there be a protective uncertainty or safety factor of at least ten to protect consumers applied to 2 or 4 which would protect teeth from moderate dental fluorosis which a recent Health Canada is concern at 1.56 ppm and from severe dental fluorosis which the 2006 National Research Council (NRC) said was an adverse health risk at 4 ppm which would also protect brains, EPA Defense attorney said that would be an interesting thought experiment, but Plaintiff attorney didn't argue about dental fluorosis (which by the way is positively associated with lower IQ and learning disabilities) so the judge could not legally do so. Frankly, it almost seemed like the EPA attorneys were threatening the Judge. 

 

Judge Chen pushed back about EPA "Health Protective Assumption" guidelines, but EPA insisted that the Judge must not act based on science or consumer protection, but on strict interpretation of statutory law and the skill of the Plaintiff attorney in proving his case. 

 

On the other hand, Plaintiff attorney was clear that the Toxic Substances Control Act (TSCA) only requires that any specific use of a chemical (fluoridation programs) not pose an "unreasonable risk" to consumers which include susceptible sub-populations like pregnant women and their offspring and bottle-fed babies. All five plaintiff witnesses were quite clear that optimally fluoridated water per CDC guidelines is subtly and permanently damaging the brains of millions of children. Even EPA witnesses and attorneys admitted that there is "something there" in the scientific evidence showing neurotoxic effects at 0.7 ppm, but argued it is not clearly defined enough to identify a "Point of Departure" for the EPA to perform a risk assessment. 

 

Really? 

 

Three Benchmark Dose Analyses which are the gold standard for beginning risk assessments and established uncertainty factors have identified that 0.2 mg/L, which is one tenth of 2 ppm, as harmful. This suggests that no fluoride exposure is safe for baby brains and is a scientifically justifiable Point of Departure in anyone's book.  

 

BMCLBMCL

 

But let's make it even easier for thick-headed fluoridationists to understand: 

  • No amount of fluoride in water or food is safe for pregnant women and their fetuses; bottle-fed infants and young children; the elderly and any in fragile health, such as diabetics or those with thyroid or kidney disease.

Ken,

 

I agree nutrition is a confounding issue in almost all health studies.  But I would disagree that the few studies showing no neurotox effect of fluoride had good nutrition control and those showing IQ loss were all flawed.  And the NZ study did not compare total fluoride ingestion, water sources were problematic, and other flaws.  The Swedish study had serious flaws.  All have limitations.  

 

We are looking for safety, not absolute proof of harm.  

 

Would you agree, dental fluorosis is a sign of excess fluoride ingestion prior to age 8 while the teeth are developing?

 

Would you agree with the NRC 2006 report that severe dental fluorosis is an adverse health effect. . . harm?

 

Would you agree with the NHANES 2011-2012 survey in the USA that 2% of adolescents have severe dental fluorosis, 20% moderate or severe?

 

If so, then you would agree that 2% are being harmed from excess fluoride exposure.  

 

Is 2% of adolescents (and growing) harmed OK with you?  What percentage of the population harmed would not be acceptable to you?  At what point would you say too many are ingesting too much fluoride?

Bill, it's not a matter of studies being "flawed." All studies have limitations - its a matter fo discussing them.

The Broadbent study was part of the world acclaimed Dunedin study and therefore had many advantages. It did answer the question of whether fluoridation itself caused cognitive deficits - which has been the claim of the Connett crowd for the last few years. It doesn't.

Any limitations are minor compared with those of the poor quality Chines studies made in areas of endemic fluorosis - the most obvious of those limitations is that those studies had nothing to do with fluoridation and that health problems are very common with people living in such areas.


Specifically, there is no evidence that F intake was unusual in the NZ study - drinking water could be presumed to be the main source. Water sources were "not problematic" - there was either CWF or not. And "other flaws" is simply a copout. You cannot find anything of significance wrong with that study.

I have asserted that the major limitation of that study (and of most other studies to a large extent) is the confidence intervals - the sizes of which are determined by sample number. For this reason, Broadbent has pointed to the Swedish study as being more important in that CIs were very low as the sample numbers were very high.

 

You do not say what the "serious flaws" of the Swedish study were - I can only assume that in the eyes of the Connett crowd the "serious flaws" in all fluoridation studies is that they do not give the answers Connett wanted. If they did he would have been lauding those studies as the best things since sliced bread. Their disgusting behavior over the NTP study shows this - Connett predicted that study would lead to the end of fluoridation worldwide and was very flattering in describing the study - until it produced a result he did not want (no effect of F on cognitive abilities). Now he and his crowd are slandering the research and the researchers.

Yes, dental fluorosis of serious or moderate form is a sign of excess fluoride and it is the sole factor used in defining the upper limits in drinking water. The research indicates that in communities where community water fluoridation is used (and therefore in which drinking water does not contain excessive fluoride) the major cause of dental fluorosis is excessive consumption of other fluoride sources - mainly ingestion of toothpaste.

No, that 2% with moderate or severe dental fluorosis is not something to be happy about. That is why health authorities do campaign on how children should use toothpaste and how to avoid excessive consumption of toothpaste.

I look forward to your response to my comments on the Bashash studies - the comments which CaryAnne simply refuses to respond to as she avoids any proper scientific exchange.

Ken,

Take the blinders off.  You really frustrate me.  I feel like I'm communicating with a brick wall.  

 

The Broadbent study has serious limitations and incapable of determining harm.  I've gone over that study with you before.  Why are you still quoting the mythology of Broadbent?

 

Come on man.  Think.  

 

Most of the controls were taking fluoride supplements.  No urine or serum fluoride concentrations were measured.  

 

The study compared water fluoridation (assuming some or all were actually drinking the water) with fluoride supplements (assuming most or all were taking fluoride supplements).  And there were other confounding factors as I remember of polution, urban/rural, lack of measured data etc.

 

Ken you make no sense.  You are not capable of understanding total exposure of fluoride.  You evade and avoid the foundation of science.

 

If you are standing in water up to your nose and someone adds 2 more inches of water and you drown, which two inches of water is to blame?  The total amount of water caused the drowning.  

 

There are many sources of fluoride and many are ingesting too much fluoride from many sources; medications, foods, pesticides, post-harvest fumigants, toothpaste, etc.   

 

Because too many are ingesting too much fluoride, what source of fluoride should be reduced?    What caused the excess?  All sources, not just water fluoridation.

 

It is a no brainer, intentionally adding more fluoride to people already ingesting too much fluoride is barbaric.  STOP fluoridation is logical because fluoridation serves no other purpose than the mythology of mitigating/preventing dental caries 

 

You want me to discuss with you, but you fail to answer the obvious questions on dosage because you do not have answers for the obvious essential questions.

Bill, I wish you would back away from the personal attacks. I know this is encouraged by your colleagues in the Connett crowd - but come on. You are surely capable of a good faith scientific exchange. Instead of attacking me when you think I am wrong point to the evidence. That is what I respect. I have no respect for personal attacks or ideologically motivated propaganda and distortion of the science.

You say the "Broadbent study has serious limitations and incapable of determining harm. " But you don't list the "serious limitations." I assume you mean the Connett/Hirzy analysis when you say it was "incapable of determining harm." This is just another way of saying the effect (which you assume, without evidence, must be there) is so small it cannot normally be detected because of limitations of sample size. The sample size used by Broadbent was already largest than most studies bunt the Swedish study used a huge sample size and still could not find the negative effect you hope for.

(I suppose you will also fall back on this argument for the fact that the Bashash study was unable to show a relationship of child urinary F to IQ).

The overlap of treatments, (fluoridated, non-fluoridated, supplements, breast feeding, etc., is accommodated by the multiple regression analysis. Any extreme overlap will increase the sizer of the CIs, sure, but that is all. Partial overlap does not nullify the results - you are confused because this is not the sort of study that the Connett crowd usually promotes - comparison of two villages in China. It is a multi-factorial study using multiple regression.

It is truly silly to sate as you do:

“The study compared water fluoridation (assuming some or all were actually drinking the water) with fluoride supplements (assuming most or all were taking fluoride supplements).  And there were other confounding factors as I remember of polution, urban/rural, lack of measured data etc.” This was not a two-factor study – it was a multi-regression study.

You are perhaps unaware that the Dunedin Multidisciplinary Health & Development Study has a very high approval and status internationally. It is truly impressive. You are wrong about factors measured because blood tests (and I think urine tests) are regularly made.

The huge amount of data enabled Broadbent et al to answer all the criticisms made of their study by going back to the data and including new data (for example Pb) in the regression. It is a truly very useful and thorough study which has produced a large number of publications:

https://dunedinstudy.otago.ac.nz/publications

Bill, you are the one who should think. And to think properly you need to abandon the chains of your bias. Considering you are embedded in the Connett crowd I can understand this is difficult for you. But you could make a start by avoiding personal attacks and instead deal with the facts as I present them and as the studies present them.

What about moving on from the Broadbent et al study - you are not going to win that one considering the high credibility it has. What about dealing with my critique of the Bashash studies – after all the Connett crowd seem to think these are the best thing since sliced bread now (although that might change if Bashash et al ever get around to including maternal nutrition in their multiple regressions.

Ken.

 

Broadbent 2015, "Community Water Fluoridation and Intelligence: Prospective Study in New Zealand."

 

Consider Table 1.  

 

CWF =                          891 cohorts.

Never lived in CWF =     99 controls.

 

Fluoride tablets    =      139 participants.

 

Stick with me Ken, this is something that for years you have failed to grasp about the Broadbent study.

 

Seldom do doctors prescribe fluoride in fluoridated communities.  Double dose is not recommended.  Therefore, we can assume, most of the 139 on pills were in the "Never lived in CWF" group of 99.  

 

Slow down, calm down, read that again.  The purpose of a doctor prescribing fluoride tablets is because the patient is not on fluoridated water.  Therefore, from a clinician's point of view, most of the 139 on fluoride tablets were part of the 99 non-CWF controls. Broadbent does not address this huge problem which makes the study incapable of determinging an IQ difference.   

 

And further:

 

The methods state, " Residence in a CWF area, use of fluoride dentifrice and intake of 0.5-milligram fluoride tablets were assessed in early life (prior to age 5 years); we assessed IQ repeatedly between ages 7 to 13 years and at age 38 years."

 

Keep in mind:

 

"In childhood, no statistically significant difference in IQ existed between participants who had or had not resided in areas with CWF, used fluoride toothpaste, or used fluoride tablets, both before (Table 1) and after (Table 2)  adjusting for potential confounding variables."

 

Apparently, IF fluoride affects IQ, the source of fluoride did not appear to make a difference.

 

Breastfeeding showed higher IQ irrespective of 0.3 or 1.0 fluoride in water or fluoride supplements. 

 

Did the cohorts actually drink the water or bottled water?  No mention.

 

In other studies, water district claims for fluoridation of each house were not accurate by about 10%.   Did the cohorts actually drink the water and how much water?  Broadbent says, "A limitation is that we did not ask how much water study members drank. Individual water-intake level was not directly measured, meaning that the CWF exposure variable is an ecological one."

 

What percentage of fluoride exposure comes from public water?  "Other sources of fluoride are also important in assessment of total intake. Prior to age 5 years, water intake is thought to account for less than half of total fluoride intake among children."

 

Ken, digest the statistics.  The study is comparing about half the fluoride exposure for CWF.  

 

Broadbent states: "Dietary fluoride was not considered, although we did consider exposure to fluoride from dentifrices and fluoride tablets."

 

Urban/rural was not considered, although most without CWF were in satellite suburbs.

 

Broadbent did not report the calcium or other mineral concentrations in the water which also affects dental caries.

 

 

 

Broadbent had no controls and compared fluoridation exposure with fluoride tablet exposure.

Bill, you confuse the issue when you say of Broadbent's study - "Most of the subjects (if they were drinking the public water) were on fluoride supplements." From the figures, you then cite this is patently untrue.

But the basic problem in your approach is that you do not understand that this is a multivariate study - not a simplistic bivariate study of the sort reported in the poor quality Chinese studies you rely on which compared two villages - one in an area of endemic fluorosis and one not.

Put simply - there are no "controls" - there are treatments." - multiple "treatments."

Yes, the overlap of treatments influence the confidence intervals of the result of the multiple regression. This is inevitable. That I why I have said that the main flaw is that the size of the CIs influences the sensitivity of the detection. Or, in other words, the IQ effect (which you assume without evidence occurs) is so small that it is not detected by the regression analysis.

One can drive that argument to infinitely small effects, as for example with the Swedish study which had very large sample numbers.

You assume that only the residents of the nonfluoridated area (and then all the residents of that area) received supplements. The numbers show that is patently untrue and again you completely ignore the results of the statistical analysis which teases this sort of theing out in the size of the resultoing CIs.

The fact that you keep talking about "controls" shows your lack of understanding. You do not understand that this was not like the studies with what Broadbent et al refer to as "simplistic methodological design" that you put so much faith in.

Search through the paper and you will see Broadbent do not use the noun "control" in the way you do.

You go on to claim that Broadbent ignored other sources of F intake. The authors responded to this claim in the paper replying to the critique form the Connett crowd. (By the way, I wish that, in your consideration of this study, you would actually refer to both papers. The fact that you don't often means you are attempting to break through open doors - arguing a point the authors have already dealt with).

It is interesting that Connett and Hirzy seem to give up on the supplement argument to instead argue, vias motivated reasoning and poorly-based calculation, that the major F intake in fluoridated communities does not from the water but from other sources. They effectively say that scientific investigation of communities like New Zeland would not pick up a fluoridation effect on IQ. 

Of course, this is wild speculation on their part (and partially explains why they could not get their paper published in a reputable journal so had to fall back on "Fluoride." And I think they do not believe it themselves - if they did they would stop campaigning against community water fluoridation but instead would campaign against all the other sources of fluoride which the had argued were more important.

Ken,

 

Looks like we agree on much, regarding Broadbent.

 

The study essentially compared two sources of fluoride (fluoridation and fluoride tablets) with IQ and there were no controls.   Bravo.  We agree.  I use the word controls because most people reading the title and conclusion and study assume Broadbent was comparing fluoridation and no fluoridation with IQ.

 

And the title and conclusions are misleading, devious, fraudulent, flawed, fake science or misleading. . . take your pick.  Typical fluoridationist half truth lies.  Same type of flawed reasoning goes with cancer/fluoride studies.  Compare two cancers and fluoride. . . no difference between the two cancers but a huge difference in cancer free patients.

 

Broadbent concludes, "These findings do not support the assertion that fluoride in the context of CWF programs is neurotoxic."    I would agree if Broadbent had continued, "when compared with fluoride tablets"

 

However; Ken, do NOT every simply state that the Broadbent study is evidence fluoridation is not  neurotoxic unless you add a phrase such as, compared to excess fluoride from other sources.  

 

I have been hammering at you to consider dosage.  As a prescribing doctor, daily I consider mg/Kg body weight to prescribe medications.  The same applies to fluoride regardless of the source.

 

I have never seen your reply to my questions on dosage.  You evade the most serious fundamental dispensing questions because once anyone goes down that path they must ethically and scientifically reject additional fluoride supplementation through either fluoridation or tablets .

No, Bill, we do not agree. Please stop this playing.

We are miles apart because you continue to treat the more sophisticated methodology used by Broadbent et al as if it were the far more naive methodology used by the poor quality Chinese studies comparing areas of endemic fluorosis with other areas. Studies the Connett crowd consider as "ideal" (because they fit their biases) yet they have many flaws and should not be used to make the absolute conclusions you do.

The study did not "compare two sources of fluoride."  It investigated a number of possible risk-modifying factors for their influence on IQ at various ages using multiple regression. The two-factor type study you talk about could never have, for example, shown a positive effect of breastfeeding.

You excuse your use of the word "controls" - never used by Broadbent et al and entirely inappropriate for this study - by referring to "most people." You are simply displaying you bais and forced misunderstanding because most sensible people understand statisical analysis would recognise this word is completley inaapropriate.

Again youi dispaly your unwillingess to look at such studies sensibly by refusing to consider that all the objections raised by the Connett crowd were dealt with by Broadbent in their second paper. This showed that whereas they had not considered all other forms of F intake (they did consider some like toothpaste) in their first paper becuase they considered them unlikley to ahve an influence - they did consider them in the second paper and showed they had no influence. (Effectively Hirzy and Connett came to a simiolar ocnclusion, although the data they used was highlky motivated and was not appropriate for New Zealand).

My response to you on "dosage" has been presented several tuimes. I cannot help if your bias prevents you from understanding my response.

The word has no more legitimacy to the discussion of fluoride than it has to the discussion of iodine or selenium intake. Or any other nutrient. Neither of these nutrients should be treated like a highly active drug where intake must be accurately controlled.

Ken,

 

All the people in the Broadbent study were on extra fluoride.  

 

If everyone in the study is taking fluoride, then detecting an effect from the fluoride is not possible.  

 

And I have failed to see your answers to my questions.  Please post again.  I am busy and don't always read all the posts here, so please also send it to my email at bill@teachingsmiles.com.  

 

And Randy, you want me to take the science to those "experts" who evaluate the science and create the consensus.  Wonderful, please list those individuals or the organizations who create the "consensus."   I've been trying to find them and no one accepts responsibility.   Forward me the names please.

Bill -please support your claim - "All the people in the Broadbent study were on extra fluoride."

As it stands it is simply a declaration - which is ideological/political. It is certainly not a substantiated scientific statement.

You could support your claim in either of two ways:

1: Provide the list of samples with the treatments (actually this should be available but not expected to be published);

2: Cite the infinite confidence intervals that would result if this claim were true.

I have not seen the specific individual data and have no interest in attempting to get it. But I have seen the statistical analysis and the results a quite inconsistent with your claim.

So I can only conclude you have pulled that claim out of thin air, or somewhere else. It is certainly not factual.

I am unaware of questions I have asked you that refer to - except to deal with my comments on the Bashash studies. These were what motivated you to intervene in my discussion with CarryAnne and you seem completely unaware of the problems in those studies, such as the poor nature of the relationship, the lack of any relationship with child urinary F and the need to consider other important risk-modifying factors like maternal prenatal nutrition.

Ken,

 

If I tell you the data on Broadbent, you will not spend the time to read the study again and evaluate the the flaws.

 

How many cohorts were subjects on fluoridated water?

 

How many were controls?

 

How many of the controls were on fluoride supplements?

 

What was the difference in the polution in the water between the two areas?

 

My point is,

 

Most of the subjects (if they were drinking the public water) were on fluoride supplements dispensed as fluoridation.

 

Most of the controls were on fluoride supplements dispensed as pills/liquid (if they took the pills).

 

The difference in dosage of fluoride between the two groups was too small to detect IQ loss.

 

This is probably the 4th time in the last few years I have repeated that the Broadbent study was incapable of determining IQ loss and is certainly not evidence ingesting fluoride is safe. . . Broadbent compared two sources of fluoride and found both to be about the same.

What? Fluosilicic acid preparations are not pure. The best grade available commercially I am aware of is only a technical grade. And it cannot be purified more concentrated than a 23% solution because further evaporation emits toxic fumes of hydrofluoric acid..

Of course fertilizer manufacturers don't re-add toxic fluorides back into fertilizer. Industiral fluoride is an enviromental pollutant, Released HF from fertilizer manufacturing is trapped in wet scrubbers to prevent the HF from poisoinng the surroundings.

The fluosilicic acid preparations from China are contaminated with bird droppings from the dead birds that fly over the exposed piles of the material sold to U.S. water districts for their bone fluoridation program as though it is an oral ingestible dental prophylactic (personal communication with the late Jeff Green, fluoride environmental attorney).

Richard, I thought from the context I was clearly talking about purity in the sense of heavy metal contaminants. No one considers water a contaminant.

I know this from personal experience having used fluorosilicic acid in my research and being particularly interested in its heavy metal content. I was surprised it was so low - one of the things which made me realise how anti-fluoride activists had been misrepresenting the literature and lying about "toxic cocktails.

Also, Richard, you seem unaware of the situation in NZ I was talking about. Manufacturers will do things like returing the fluorosilicic acid to the fetrtilsier mix in an effort  to produice the best granulation. Obviously, changes in granulation procedure may be the response to current concerns but, as I point out, the production of the pure calcium phosphate fertilisers would be the best approach (but maybe not the most economic).

And when pray tell did I make such a claim about 3 samples? And 3 is better than none.

The radioactive materials added have toxicity that is more related to how long the exposure is during the life of an individual whose bones can irreversibly trap and hold it.So no one has the right to intentionally add the garbage into peoples' drinking water in the first place..

There are no known MCLs for combinations of all these congtaminants ingestwed at the same timwe. The alloed leverl for arsenic is 15 ppb and for lead is 15 ppb, but these are from studies on the toxic effects (mainly cancer) produced separately when the other is absent. Both arsenic and lead bind protein sulfhydryls and the presence of both together at 15 ppb each has not been evaluated. No studies, don't add anything that contains them both.

And the samples from China I suspect are far more contaminated since China does not fluoridate their own people. They sell their garbage piles to the U.S. water distrricts who willingly do that.it.

Get a grip. No one needs credentials to understand that fluoridation is harmful, useless, illegal, and immoral. 

A most important Christian teaching is that God is so magnanimous to man that humans are given a free will. Fluoridation takes away one's free will to drink fresh God given drinking water because water that is provided in a home by a city must be consumed to remain hydrated and living. When fluoride comes with it, it is unavoidable and free will disappears.

Fluoridation alters the chemical composition of every person's body who consumes it and alters the crystal structure of bone which weakens bone (See U.S. CDC ATSDR 2003). Even CDC scientists know this while the CDC endorses fluoridation and takes away rights of people who are supposed to have a free will.

What credentials are needed to understand this?

Oh course, if KenP had looked at the history of this thread beginning in Feb 2015, he would see I posted considerable scientific studies with discussion and that approximately 20+ seniors amiably joined in over a period of 3 years. That ended in June 2018 when the fluoride trolls descended en masse.

 

Regardless of the opinion of a retired agricultural chemist from New Zealand whose job was to develop fluoride-intensive fertilizers and pesticides, the epidimiologists, neuroscientists, and other scientists who published or read the recent peer-reviewed and high-quality studies listed as medical science rather than agricultural science are very alarmed about the implications relevant to fluoridation policy.  I have read them in full. 

 

THYROID: 18% of people drinking 'optimally' fluoridated water in Canadian communities have a heightened risk of low thyroid function because fluoride interferes with iodine metabolism. Many of them will be sub-clinical and not know they are mildly hypothyroid, which nevertheless increases their risk for diabetes, high cholesterol, and other problems. Study excluded those already diagnosed with thyroid disease.

PREGNANT WOMEN: Pregnant Canadian women drinking  'optimally' fluoridated water had twice the fluoride exposure per individual testing as compared to pregnant women in non-fluoridated Canadian communities - and consistent with the range in the Mexican women whose children had up to 6 points lowered IQ based on prenatal exposure to fluoride (from salt). Excluded those with health conditions such as kidney disease as well as considered confounding factors such as tea consumption.

LEARNING DISABILITIES: Over 200 children were individually tested. Study found attention deficit disorder apparently caused by their prenatal exposure to fluoride specific to dose. This is the 3rd report out of the NIH sponsored 12 year study that seems to have been designed with the intention of showing no ill effect, but instead has three times confirmed low dose prenatal exposure to fluoride consistent with exposure in 'optimally' fluoridated communities causes subtle but permanent brain damage for many consumers.  Excluded those with history of mental illness or conditions such as diabetes and renal disease.

OVERDOSED BABIES: Over one third of babies (37%) in fluoridated American communities consume amounts of fluoride in excess of the upper limits of fluoride considered safe per government regulations. Even 4% of babies in non-fluoridated communities are overdosed on fluoride due to consumption of products made with fluoridated water. At the very least, this puts these children at high risk for developing dental fluorosis, which is associated with increased incidence of learning disabilities, broken bones and kidney disease.

Yes, I see you download citations and make claims about them - in bulk. But no discussion.

This is not the place for an extensive exchange on all your citations so I will just respond to one of them - the Bashash et al (2018). I am very familiar with this and have written a document which is relevant:

https://www.researchgate.net/publication/330897483_Evidence_linking_attention_deficit_hyperactivity_...

While these studies do suffer from the problems of using data not designed for the hypothesis they test and the urinary F spot measures are really inadequate, I have concentrated on the over advocacy of the regression analysis results.

Yes, they were able to find a few parameters (not all they tested) that were significantly related to maternal urinary F but, like the earlier IQ study, the regressions are poor. An R-squared value of only 3% really does not suggest there is a real problem - especially as when more important risk-modifying factors like nutrition are included, the relationship with urinary F would probably disappear. (I found that the Malin and Till 2015 study also suffered from not including relevant risk-modifying factors - when they are included, the relationship with fluodiation disappears completely - see my paper:
https://www.researchgate.net/publication/321457780_Fluoridation_and_attention_deficit_hyperactivity_... )

 

Bashash et al (2018) do acknowledge limitations in their study and specifically mention nutrition as one. They imply they will do more work to include this. As Malin et al  (2018) found significant relationships between maternal nutrition and child IQ parameters with a subset of these child-mother pairs it will be interesting to see the results of including maternal nutrition in Bashash et al's regressions. Malin et al (2018) explained more of the variance (R-squared value over 11%) so I look forward to future publication from the group.

By the way, your claim that my "job was to develop fluoride-intensive fertilizers and pesticides" the is an absolute lie. I never worked with pesticides - or the development of fertilisers. You should be ashamed of lying in this way and it certainly undermines any claim you have to credibility.

Please stop such personal attacks and concentrate instead on good faith scientific exchange.

Claims that fluoride is related to cancer are mistaken.

 

An exhaustive review of all the scientific data was done by the California Carcinogen Identification Committee.   Full briefs were filed by a number of fluoridation opponents.

 

The commmittee, composed of a scientists with broad technical expertise voted unanimously that fluoride is NOT ASSOCIATED WITH CANCER AT ANY concentration.

 

All of the documents considered may be viewed here:

http://www.oehha.ca.gov/prop65/public_meetings/cic092311.html

 

Formal reviews by expert panels are the highest quality of scientific information.   There really is nothing more to discuss re fluoride and cancer.

I'm a native Californian and am fully familiar with the CA DPH analysis on fluoride carcinogenicity. They did not perform any experiments. They simply analyzed published materials. And again humans cannot be caged so they are limited to the data that was published by those humans who are not caged.

Most important, the Committee did not consider the Yiamouyiannis data because they were only looking for carcinogenic potential, not mortality incidence from extant cancers.

Their conclusion was that the evidence available in man does not prove fluoride causes cancer.

So what?

The Yiamouyiannis data prove that fluoride increases mortality in those who have cancer. lt appears to inmpair ones ability to fight cancer after it develops.

Again what is so difficult for you to grasp? And why is it my fault you cannot grasp it?  You call me names but have no justification for it. Give it up.

I haven't looked too deeply into the fluoride-cancer issue, except for specifically analysing a few papers. But one thing that strikes me is that the reports anti-fluoride activists rely on usually have inadequate statistical analyses. For instance, ignoring the very low explanatory power of the relationships reported (low R-squared values) and ignoring other risk-modifying factors (which when included show that there is no real relationship with fluoride.

I discussed these problems with the Takahashi et al., (2001 paper here:

1950s

  • "More doctors smoke Camels than any other cigarette" 
  • "Ask your dentist, I would recommend Viceroys!" 
  • "Scientific evidence on the effects of smoking - Chesterfields are best for you!" 

2018

A Federal Court has ordered Altria, R.J. Reynolds Tobacco, Lorillard, and Philip Morris USA to make this statement about the health effects of smoking.

  • Smoking kills, on average, 1,200 Americans. Every day.
  • More people die every year from smoking than from murder, AIDS, suicide, drugs, car crashes, and alcohol, combined.
  • Smoking causes heart disease, emphysema, acute myeloid leukemia, and cancer of the mouth, esophagus, larynx, lung, stomach, kidney, bladder, and pancreas.
  • Smoking also causes reduced fertility, low birth weight in newborns, and cancer of the cervix.

We all live in our own time and are consequently subject to opinions of those times. We all remember that even after it finally was accepted that smoking kills, the tobacco giants insisted there was no danger from second hand smoke - right up until a few years ago when internal memos revealed they knew for decades that even 2nd hand smoke causes cancer and other disease.

 

  • Fluoridation is on its way to having the same reveal, and fluoride players are just as desperately trying to 'win' the argument with disinformation campaigns.  

As to the cancer data, cancer isn't my go to but I hate to see tobacco style misdirection from today's fluoridationists that misrepresents historical as well as scientific facts :

 

“I know of absolutely no, and I mean absolutely no means of prevention that would save so many lives as simply to stop fluoridation, or don't start it where it is otherwise going to be started.” - Dr. Dean Burk, biochemist at National Cancer Institute (1982)

"Over the course of five months (in 1978), the court held periodic hearings, which consisted of extensive expert testimony from as far away as England. At issue was the most recent time-trend study of Dr. Burk and Dr. Yiamouyiannis, which compared cancer mortality in ten cities which fluoridated their water systems with ten cities which did not fluoridate over a period of twenty-eight years from 1940 to 1968. The study concluded that there was a significant increase in cancer mortality in the fluoridated cities..My decision regarding the fluoridation of the public water supply, made during my tenure as a trial judge almost twenty years ago, was on appeal, purely a jurisdictional issue... That the practice is deleterious is more and more accepted -- its utility doubted." - Judge John P. Flaherty, Chief Justice in the Supreme Court of PA (1996)

  • in HIGHLIGHTS IN NORTH AMERICAN LITIGATION DURING THE TWENTIETH CENTURY ON FLUORIDATION OF PUBLIC WATER SUPPLIES by JR Graham  & P Marin, J. Land Use and Envtl. Law, Vol 14:2 (Spring 1999) 
    • In response to NIH objections: “Dr. Burk and his colleagues had a remarkable answer:  The available and pertinent data for the years after 1950, were 1953-1968. Without the trends in these years, nobody would suspect that there is a causal relationship between fluoridation and cancer. In its adjustment, the NCI considered l950 before fluoridation began in the experimental cities, and 1970 after fluoridation had already been initiated in the control cities, and did not consider the years 1953- 1968 which were the whole basis of concern. In other words, the NCI simply derived their CDRo values from data reported for 1950 and 1970, and ignored all else, as if 1953-1968 were unimportant. 

    • Having omitted all available and pertinent data in their adjustment, it is not surprising that the NCI came up with the wrong answer. In the same hearings before Congress, it was demonstrated by a colleague of Dr. Burk that, if the adjustment proposed by the NCI is undertaken using all available and pertinent data after 1950, there emerges an impressive association between fluoridation and age-race-sex adjusted cancer mortality.”

David,

 

Like you, I questioned whether fluoride caused cancer.  Instead of going to a historical news society column, I went to PubMed and did a search for the words "cancer" and "fluoride"  in the primary literature.  Try it.  

 

In reading the articles, I came on one where a pharmaceutical company was testing their cancer TREATMENT drug on live animals.   The drug showed promise in curing the cancer.

 

Of interest to me was how they caused cancer in their test animals.   After all, finding a hundred cancer animals of the same age and cancer would be rather difficult with many many hundreds of thousands of animals or millions to find the cancers to test.  Imagine raising all those animals and simply testing each animal for cancer, the stage and kind of cancer.   An unimaginably massive and cost prohibitive task.

 

So the pharmaceutical companies CAUSE cancer in the animals.   That's right.  They cause the cancer so they can test the new cancer drug.  Not so human, but at least they get the cancer animals to test in a predictible timely manner.

 

Can you guess what chemical they used to CAUSE the cancer to test their drug?

 

You guessed it.  SODIUM FLUORIDE.

 

To argue that fluoride does not cause cancer shows a lack of careful evaluation of the literature.

 

The arguement is dosage, synergistic chemical effects, host sensitivity, genetics, etc.

 

With two thirds of children showing a toxic overdose of fluoride ingestion, hundreds of new untested chemicals being created each year, synergistic effects of known cancer chemicals, it is long past time to reduce total exposure.

 

Perhaps the final truth on all science has not been discovered and we need a safety factor, a margin of error, a "we don't know everything" and protect the public rather than assume government scientists are not politically influenced.

I'm going to go out on a limb here and say this is pure fiction:

 

"In reading the articles, I came on one where a pharmaceutical company was testing their cancer TREATMENT drug on live animals.   The drug showed promise in curing the cancer.

If anybody wants to prove me wrong, now's the time.

Have those here even read the CA OEHHA report on fluoride and cancer below?

A key finidng is that fluoride transforms (converts normal cells to cancer cells) mammalian tissue cultures. The NRC 2006 Report tried to dismiss these data by claiming it has no relevance to humans. The CA review stated that the effrect has been confirmed repeatedly and that there is no evidence to justify the claim that it is irrelevant to humans..

Knowing how difficult it is to control humans in cages, and that it is not possible to study the possible carcinogenic potential of fluoide over lifelong time periods, to determine whether fluoride is carcinogenic or not, the serious effect proven in cultured mamalian cells is far too troubling to be laughed off. .

The Yiamouyiannis data was considered in the report and also in the CDC ATSDR full report 2003. No one can disprove it though many have tried, where fluoride inhibitis the immune system in fighting cancer and increases cancer morlality when it is present.

Get the crap out of our water..
