FLUORIDE ACTION NETWORK http://www.FluorideAlert.Org FAN Bulletin 997: New Video: Vyvyan Howard's Toronto presentation
August 17, 2008
I am happy to tell you that an edited version of Dr. Howard's August 11 Toronto presentation "Fluoride and the Developing Nervous System" is now available on Google video. This 30 minute tape can be accessed at http://video.google.com/videoplay?docid=4072416559052593081&hl=en
The evidence that fluoride lowers IQ is stronger than we thought.
In Dr. Howard's presentation he used a systematic review of all the studies that have suggested that fluoride lowers IQ in children. 18 our of 20 studies have found this association. This review, authored by Michael Connett and Hardy Limeback, was presented at the International Association for Dental Research (IADR) in Toronto earlier this year. We have just found out that ANOTHER systematic review of this literature has been carried out by Chinese reviewers (Tang et al.). Their review appeared in the journal Biology of Trace Element Research and the abstract of the paper available is printed below. The authors, who only reviewed Chinese studies, concluded that "children who live in a fluorosis area have five times higher odds of developing low IQ than those who live in a nonfluorosis area or a slight fluorosis area."
This review paper underlines the importance of FAN's work not only in trying to end fluoridation worldwide by education and organization but also by making scientific research more available to both the public and the scientific community. It was FAN that had 19 Chinese studies on the brain translated into English. It was these studies which not only formed a large basis of the Connett/Limeback meta-analysis, but in addition, 12 of these English translations, were featured in a recent issue of the journal Fluoride. It is interesting that the Chinese authors of this second Meta-analysis cite the website of the journal fluoride (www.fluorideresearch.org) in their abstract below. It is thus conceivable that in addition to most of the western scientific community being unaware of these important Chinese studies, that some Chinese researchers may have been unaware of how extensively their own scientists have studied this issue.
A preliminary review of the 16 studies reviewed by the Chinese researchers (they did not review the recent papers from India, Mexico and Iran) indicates that there are some more studies from China of which we had been unaware. So there now appear to be over 20 studies which are associating a decrease in IQ with over-exposure to fluoride. With dental fluorosis now impacting 32% of American children (a clear indicator of over-exposure to fluoride before the permanent teeth have erupted) this should be a matter of grave concern for all those countries which practice water fluoridation.
Doubtless, diehard fluoridation promoters will claim that the exposures in these studies is "much higher" than exposures in fluoridated countries. However, such a rationale for dismissing their relevance is neither scientific nor responsible. Most of these studies were conducted on relatively small populations and to protect the whole population of children - with a large range of sensitivity due to different body weights, different diets (including the all-important iodine intake), different health status and kidney function -drinking uncontrolled amounts of water, juices and soft drinks (made using fluoridated water) as well as fluoride from many other sources - one needs to apply at least a margin of safety of 10 to be protective. The Xiang (2003) study estimated that IQ would be lowered at 1.8 ppm. There is simply NOT an adequate margin of safety to protect our whole population from fluoride's potential to interfere with developing brain, when consuming water at about 1 ppm, especially babies.
Nature gave its own verdict on this matter when it set the level of fluoride in mothers milk at 0.004 ppm (NRC, 2006, table 2-6), some 250 times lower than 1 ppm.
We have to get this message out to the more responsible and less brain-washed members of the medical community. This is what our Triple event in Toronto set out to do. In this Dr. Vyvyan Howard played a truly magnificent role.

Fluoride and Children's Intelligence: A Meta-analysis.

This paper presents a systematic review of the literature concerning fluoride that was carried out to investigate whether fluoride exposure increases the risk of low intelligence quotient (IQ) in China over the past 20 years. MEDLINE, SCI, and CNKI search were organized for all documents published, in English and Chinese, between 1988 and 2008 using the following keywords: fluorosis, fluoride, intelligence, and IQ. Further search was undertaken in the website www.fluorideresearch.org because this is a professional website concerning research on fluoride. Sixteen case-control studies that assessed the development of low IQ in children who had been exposed to fluoride earlier in their life were included in this review. A qualitative review of the studies found a consistent and strong association between the exposure to fluoride and low IQ. The meta-analyses of the case-control studies estimated that the odds ratio of IQ in endemic fluoride areas compared with nonfluoride areas or slight fluoride areas. The summarized weighted mean difference is -4.97 (95%confidence interval [CI] = -5.58 to -4.36; p < 0.01) using a fixed-effect model and -5.03 (95%CI = -6.51 to 3.55; p < 0.01) using a random-effect model, which means that children who live in a fluorosis area have five times higher odds of developing low IQ than those who live in a nonfluorosis area or a slight fluorosis area.

Holy crap, you mean to tell me my IQ should be 160??? Damn flouride to hell. But my teeth look good.

WARNING ! BRUSHING YOUR TEETH MAY BE HAZARDOUS TO YOUR HEALTH !

No wonder John Doe's so smart. He probably doesn't brush his teeth.

I use "Natural Herbal Toothpaste" which does a great job without the chemicals and colourings......drinking water with flouride ALSO is said to cause miscarriage cancer and be bad for the liver and kidneys. Flouride is a known toxic chemical and when mixed with chlorine and "binding agent" chemicals your drinking a toxic cocktail from your tap!

I spoke to a dentist who said only kids benefit from Flouride in the water as fully developed adults can't absorb it.....regular brushing and little sugar would work better!

I thought there was going to be a picture of George Bush brushing his teeth when I opened this thread or something. No such luck.

I don't know about you, but I don't eat toothpaste. I usually apply it to my brush. Then in a scrubbing motion, with a bit of water, I spit it out.

100 years ago the Cancer rate was 1 in 100 today it's 1 in 3 people will get Cancer.....do the math, what is wrong with our "modern society. I love how people who don't do any research bag this thread. If you do some homework you will find it's true. Natural Treatments and healing are a hobby of mine and I have read tonnes of books on the dangers of our drinking water and or Flouride.

I'm not baggin it dude. I'm just being funny for once in my life. That said,if you have studied it. How good are water filters at trapping the flouride.
