Stop Fluoridation

1,272 Views
Message 251 of 1,444

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.

Ross, re the Hamilton city debacle - biased activists are biased activists even if they have degrees. Yes, I know Bob Mann too - and he is an extremist on this issue.

I interacted with many councillors after their initial decision and it was clear to me that they did not understand the science at all - what they understood is that there were two different stories coming from people they thought were experts. They were incapable of discussing the science and they had no idea of criteria to use to judge if a submitter was a real or a fake expert.

It is this confusion caused by activists pressuring councils which lead to the councils requesting, and partially financing, the authoritative NZ Fluoridation Review (https://royalsociety.org.nz/assets/documents/Health-effects-of-water-fluoridation-Aug-2014-corrected... and eventually pressure for legislation to take such decisions away from councils (as councils pointed out - they do not have the skills to make scientific evaluations and they considered the whole issue a "poisoned chalice" for councils). That legislation is still waiting for its second reading in parliament.

The numbers you quote are a symptom of the problem councils saw - cynical form letters and copies of letters given as submissions simply to get numbers. It’s an old activist trick.

Scientific issues should not be considered by councils, but by relevant experts. It's up to democratic bodies to consult such experts for advice - not replace them.

You list issues you claim swung the council (rather a naive understanding considering the stupid politics involved in that council at that time with competition to replace the Mayor). Let’s look at these:

1: Yes, the surface reaction of phosphate, calcium and fluoride at the tooth surface is considered the main mechanism of preventing decay and recovering from acid attack. This results from the presence of these chemical species in saliva, plaque and the oral cavity in general. Fluoridated water and food help provide these and help maintain saliva F, P and Ca concentrations during the day (saliva F from toothpaste drops relatively quickly so restoration of concentrations during the day is important.

2: Your argument for "wasted" treated water is simply an argument for a double reticulation system - one for drinking and one for all other uses. That is extremely wasteful financially and that is why such an approach is only considered for very small reticulation systems.

3: Each country approaches the involvement of F in oral health according to their own situation. CWF is not suitable for many systems (it's not suitable for many systems in NZ) and alternatives like school fluoride rinses, fluoridated salts, natural fluoride levels, etc., come in to play. In the end, each country and region make its own decision according to its situation.

4: Use of fluoridated water is not considered a risk to bottle-fed infants by health professionals - but parents who do have a concern are recommended to sometimes used alternative water sources - simply a "peace of mind" issue. Anti-fluoride propagandists always misrepresent that situation.

While there has been some concern that bottle-fed infants exceed the recommended maximum intake for F the lack of prevalence of moderate or severe dental fluorosis caused experts in NZ and Australia to reconsider the calculations. They found a flaw and there are now new recommendations showing that bottle-fed infants do not exceed the recommended F intake. See:

https://openparachute.wordpress.com/2017/04/02/resources-nutrient-reference-values/

 

5 & 6: You don’t explain. However, I have written several articles about the way that anti-fluoride activists distort the evidence and use statistical analyses incorrectly. See for example:

https://openparachute.wordpress.com/2017/12/05/anti-fluoridation-campaigners-often-use-statistical-s...

 and

https://openparachute.wordpress.com/2018/10/18/fluoridation-and-adhd-a-new-round-of-statistical-stra...

I could say that I find it bizarre that you think my attitude to democratic processes is bizarre. It is simply a matter of democracy for resolution of differences based on values or ethical issues. Yes, the minority "loses" but nothing is "forced" on them. When CWF was stopped in my city I used a mouth rinse. When it was restored many anti-fluoride activists used filters and alternative sources (2 of these provided by the council). This is what sensible people do when they feel the democratic decision doesn’t suit them - they use alternatives.

I think democracy is a win-win situation for this reason. It is simply dishonest to claim that either side is forced into anything. They aren’t

Think about free hospitals or secular education. People who object to these have alternatives and use them - at far more cost than the $250 for a filter or similar amount for a year’s supply of mouth rinse.

You say of my attitude to democracy:

"Intellectual consistency would surely force him to state that those opposing fluoridation had got it wrong.
Referendums are by far the wrong ways to resolve fluoridation disputes."

Of course, I think those opposing fluoridation have got it wrong - just as I believe those voting for certain political parties have got it wrong. But democracy means the majority decision prevails - I accept that and take alternative action if necessary.

No, referenda cannot solve scientific issues - they are not meant to. But they do resolve the values differences - providing decisions suiting most people. And as I say, usually there are alternative actions available for the minority (not for the elected government, though, and we all accept that.

You say, "Local governments face ethical issues with fluoridation." Yes, but isn't it disgusting for ideologically motivated activists to use science (and distorted science at that) as a proxy for their own ethical views. They should be honest - face up to the ethical issues and attempt to win a political decision on those grounds and not distorted scientific claims - recognising there are no black and white, facts or correct decision when it comes to values. Except that the majority should prevail.

KenP, in claiming that a 2013 (non-binding) referendum provided overwhelming support for his local council to reverse a decision to terminate fluoridation is grossly distorting history. He also asserts that the council decision to stop fluoridation was made under pressure from ideologically motivated activists who were distorting and misrepresenting the science, thereby confusing the issue.
A four-day tribunal style hearing had been held by KenP’s city council with one-and-a-half hour primary presentations from both sides of the fluoridation debate with half an hour for questions from councillors after each presentation.
The case against fluoridation and summing up was given by medical doctors, a doctor of dental surgery and the retired biochemist who had supervised John Colquhoun’s doctoral thesis and co-authored with Colquhoun ‘The Hastings fluoridation experiment: science or swindle?’
The case for was given by a large number of district health board, Ministry of Health and New Zealand Dental Association representatives.
1,385 of submissions asked the council to stop fluoridation with 170 submissions supporting continuation. Of the 141 requests to speak at the hearings only 11 wanted fluoridation to continue.
I watched much of the hearings online and also read many submissions on which the council decision was made.
On the weight of evidence presented at the tribunal there were six factors that influenced the council’s post-tribunal decision to stop fluoridation. They were:
1. Application by toothpaste or other means that directly affect the tooth surface are much more effective at reducing tooth decay.
2. Fluoridation is wasteful – of the 224 litres of water used by the average person each day, less than two litres is used for drinking – 99% goes down the drain (i.e. of the $48,000 per year spent on fluoridation only $480 ends up being fit for purpose).
3. Communities around the world are rejecting the practice – most of Europe does not fluoridate.
4. There is strong evidence that fluoride should not be ingested at all by babies under six months old and bottle-fed babies are therefore at greater potential risk.
5. While fluoridation may have some benefits for some, it isn’t good for everyone and fluoridation of the water supply affects personal choice.
6. Statistical evidence that fluoridation potentially causes harm.
Are these not reasonable factors on which to make a rational decision?
One councillor, also a district health board member, had been excluded from council decision making on the issue because of conflict of interest but within weeks had marshalled the local dental fraternity to garner support for a referendum which was eventually held in October 2013 with only around one third of eligible voters participating. Of those voting, 70 per cent voted for fluoridation while 32 per cent voted against.
The 24,635 voting for fluoridation had determined that the 11,768 against were forced, against their best judgement, to accept addition of a neurotoxin and endocrine disruptor to the water delivered through their household taps.
The district health board spent huge taxpayer funds in advertising.
As well as brochures and posters, their campaign included four huge billboards outside their buildings, three full city-wide letter box drops, two-page newspaper advertisements for four weeks in a row and Google and YouTube advertisements.
All emails from the health board and hospital had pro-fluoride messages as part of the signature, a recorded pro-fluoride message was on health board and hospital telephones and even TV screens at the hospital showed pro-fluoridation videos.
Local newspapers were blatantly pro-fluoridation.
Anti-fluoridation groups were unable to afford counterbalancing public information.
I find it quite bizarre that for KenP to admit that if referendums in his community had opposed the return of fluoridation he would have supported the outcomes. So what happens to his ‘safe and effective’ fluoride science?
Intellectual consistency would surely force him to state that those opposing fluoridation had got it wrong.
Referendums are by far the wrong ways to resolve fluoridation disputes.
Local governments face ethical issues with fluoridation.

A clear majority of pro-fluoridation voters in a poll should not be able to determine that the rest are forced against their will to take a health-affecting toxin in their drinking water.
If you are sick you don’t ask a stranger to vote on your medication so why should fluoridation be any different?

CarryAnne - I agree completely, in the current situation, with your comment that "fluoridation policy should primarily be about ethics." 

This is because currently, the science is pretty definite. Community water fluoridation is effective in reducing tooth decay and there is no evidence of harm. However, like all such social interventions, the issue is political. That is why I say that where there is controversy in the community about fluoridation proposals it should be decided democratically, involving the community. Referenda are good for this.

In my own community, it took a second referendum, confirming the first referendum of overwhelming support for fluoridation, for the local council to reverse its decision to terminate fluoridation. A decision made under pressure from ideologically motivated activists who were distorting and misrepresenting the science - thereby confusing the issue.

If the referenda in my community had opposed the return of fluoridation I would have supported that decision. I support democracy.

In fact, the ethical issue is the best argument anti-fluoridationists have. They discredit themselves when they resort to misrepresenting and distorting the science to make a "sciency" argument - but when they lose at that they resort to the ethical argument. I have seen this sort of behaviour again and again - and now with you. You should start with the ethical argument, stick with it, not attempt to use "science" as a proxy for your ethical or values concerns - and accept the democratic decisions which always decide such ethical questions.

Unlike science - which on the whole deals with factual matters, ethical considerations are based on values. There is no "correct" or factual argument to decide an ethical question. These are decided by the prevailing values - usually, by referenda or simlar democratic decsion.

Anti-fluoridationists will always lose the scientific arguments because it is determined by the facts (that is why you refuse to participate in an honest, good faith scientific exchange) but they can win the ethical one - depending on the previaling ethics of their community.

Finally, you make claims that I have used words that I certainly have no recall of using - and you do not provide any evidence. I am sure I did not use most of those terms - however the charge of describing your claim that in my scientific career I was researching pesticides and developing high fluoride fertilisers I am sure I described as "dishonest" or a "lie" - because it patently was and you  admitted it and apologised for making that dishonest claim..

Yes. An Associated Press article came out last week stating that the CDC now claims that kids are using too much toohtpaste because of the endemic of dental fluorosis. So the followers of the CDC also accept this. But yes water fluoridation began causing dental fluorosis long before fluoride toothpaste was ever invented. The original correlation that attempted to claim fluoride in water reduces caries was in the 1930's where substantial dental fluorosis was observed in communites with fluoride at 1 ppm in water. Toohtpaste with fluoride was not available until the 1950's.

The CDC has a mission to protect the Surgeon General's claim that fluoride ingestion is safe and effective, so obvsiouly it must be that toohtpaste be blamed for what is mostly done by water fluoride..But both now are involved in causing the high incidence of fluorosis enamel hypoplasia.

 

The bizarre thing is that there is no credible well controlled evidence in man or animals proving that fluoridation even works to lower dental caries. And yet vast effort and funds are put into fluoridating the country. Pretty disgusting and when this is called out, all you will get from fluoridationists is that you are somehow the 'scaremonger.'

Evidence & Ethics

”Fluoride 'science' is corporate 'science'. Fluoride science is DDT 'science'. It's asbestos 'science'. It's tobacco 'science'. It's a racket." - Chris Bryson, investigative reporter and author of 'The Fluoride Deception' (2006)

 

KenP writes 'when have resolutions at union meetings become a substitute for real science' - yet offers his blog posts to claim that the real science published by world experts is 'dishonest.'  This specific to an exchange on dose and the EPA scientists' testimony to EPA management on a scientifically justifiable reference dose for fluoride. 

 

KenP writes in his first three days on AARP that several participants are 'dishonest,' 'deranged,'  'liars,' 'unreliable' and 'so intellectually stubborn as to make rational discussion impossible,’ yet consistently writes things like "Bill, I wish you would back away from the personal attacks." 

 

KenP writes that in optimally fluoridated communities dental fluorosis is caused 'mainly by ingestion of toothpaste.'  Yet, when I offer two sources with urls and screen shots documenting dental fluorosis that predated fluoridated toothpaste (a 1956 PHS sponsored controlled dose study documenting 'coppery brown' dental fluorosis & 1962 government report that documented the first generation of children raised on fluoridated water had alarming rates of dental fluorosis, disproportionate by race in the same community), KenP replies that 'truth is your last concern,' that I made 'unwarranted claims' and spread  'propaganda' and 'fake news.' Then he says I refuse to enter into honest conversation about science?! 

 

However - fluoridation policy should primarily be about ethics

  1. Is it ethical to use municipal water to mass medicate the public? 
  2. Is it ethical to add a poison to water that is medically contraindicated for many consumers? 
  3. Is it ethical to claim more science is needed before ending a program when dozens of human studies and hundreds of animal studies have validated neurological harm from that program? 
  4. Is it ethical for anyone to dismiss the poisoning of vulnerable populations as a political decision? 
  5. Is it ethical for AARP and other organizations that claim to advocate for a constituency to remain silent?

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,

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.

CarryAnne - you should take your own advice - "Repeating a lie doesn't make it true." 

You make unwarranted claims and provide citations which often do not support them. That is simply propaganda.

Now, if you were actually willing to enter into good faith, uncensored, open exchange of the science of your claims and citations that would be different. But I think you are aware of that and your demonstrated refusal to enter into a normal human exchange indicates you are very aware you are simply in the propaganda business - truth is your last concern.

Naturally, people have built up immunity to propaganda like this. We can recognise fake news when we see it.

"Sticks and stones...." 

          "Repeating a lie doesn't make it true." 

 

The controlled dose study in the 1950s before fluoridated toothpaste documented coppery brown staining and and thin enamel in some of those children. (Prenatal and postnatal ingestion of fluorides - A Progress Report. Reuben Feltman, D.D.S. Dental Digest. August 1956.)

 

The 1962 govt memo from the first fluoridation trial city documented a disproportionate dental fluorosis impact well in excess of what predicted, again from before fluoridated toothpastes, i.e. 15% white v. 35% black children. This is why fluoridation policy is an environmental justice issue and opposed by many human rights activists. 

 

“When studying any matter, ask yourself two things: what are the facts and what is the truth that the facts bear out. Never let yourself be diverted by what you wish to believe, or what you think would have beneficent social effects if it were believed.

Look only and solely at what are the facts.”
