… is a load of crap.

For those who don’t know, apparently people are actually taking this seriously and Queensland communities are starting to ban fluoridation in water. Here’s a picture I stole off a friend’s Facebook wall – one he took on a train:

Fluoride

I first heard of this on the Q&A episode where Lawrence Krauss appeared. He was awesome as usual but had a bit of difficulty trying not to offend people and trying to dumb down his scientific explanations (particularly in regards to nothingness, which I should make a separate post on). Anyway, one of the ministers of health was there too and she mentioned some politician in Queensland – a body builder – who claimed that he’d rather take banned substances for a year than drink fluoridated water. I find this hilarious because most body builders have some idea about nutrition and he obviously doesn’t.

For those of you even farther behind in the news, fluoride is added to tap water and was one of the biggest dental intervention movements in Australian history.

My first step in exposing the bullshit of all these fluoride conspirators should be the end game. Take a look at their credentials. I saw some anti-fluoride argument on a site called “Evolution-Kills” and smelled bullshit straight away. I also found some other dodgy sites with questionable sources. This reminds me of all the quack scientists that create their own publication labels to publish their “scientific” articles because no peer-reviewed article will accept them, and the ones who create their own universities to give themselves degrees. The more scientifically oblivious may have a difficult time sifting through all the bullshit so my first step is always to look at the source.

Here’s a few sources:

The National Academy of Science: http://www.cdc.gov/fluoridation/safety/nas.htm

This report identified fluoride as a mineral that can positively influence human health, and although earlier NRC reports were not conclusive in their opinions, this report concluded that fluoride was considered to be an element essential for human life based on its role in cellular functions involving metabolic or biochemical processes. The report further stated that fluoride in drinking water has two beneficial effects: preventing tooth decay (dental caries) and contributing to bone mineralization and bone matrix integrity.

World Health Organisation Report: http://www.who.int/water_sanitation_health/publications/fluoride_drinking_water_full.pdf

Fluoride has beneficial effects on teeth at low concentrations in drinking-water, but excessive exposure to fluoride in drinking-water, or in combination with exposure to fluoride from other sources, can give rise to a number of adverse effects. These range from mild dental fluorosis to crippling skeletal fluorosis as the level and period of exposure increases. Crippling skeletal fluorosis is a significant cause of morbidity in a number of regions of the world.

… The beneficial and the detrimental effects of fluoride naturally present in water were well established by the early 1940s. High levels of fluoride present in concentrations up to 10 mg l were associated with dental fluorosis (yellowish or brownish striations or mottling of the enamel) while low levels of fluoride, less than 0.1 mg/l, were associated with high levels of dental decay (Edmunds and Smedley, 1996), although poor nutritional status is also an important contributory factor.

Now these are balanced views. No real science is going to declare an absolute benefit with no side effects – and that’s something important to note. However, skeletal fluorosis doesn’t occur in areas where fluoride levels are within safe levels (Kaminsky et al, 1990). See what I did there? Provided a proper source.

In regards to the accusation of fluoride being a carcinogenic – that’s just another example of non-scientific people trying to make scientific claims. Here’s a quote:

Some fluoridation opponents have suggested that fluoride is carcinogenic; claims which have been criticized as being based on statistical bias and deliberate exaggeration. (Cook-Mozaffari 1996, Spencer 1998, Pollick 2006) A frequently cited study by fluoridation opponents is the US National Cancer Institutes Surveillance, Epidemiology and End Results (SEER) program which reported a higher in cadence of osteosarcoma (bone cancer) among young males in two fluoridated areas of the United States . (Hoover et al 1991a) Further analysis of the time trends by Hoover et al (1991b) however found that the increased prevalence of osteosarcoma was not related to the time of fluoridation. Moreover, a similar study by Mahoney et al (1991) found no difference in the prevalence of osteosarcoma among any age group between fluoridated and non fluoridated cities in New York State .

But most of all, fluoride is in toothpaste and mouthwash. If these people truly believe that it’s poison or whatever, why don’t they just stop brushing their teeth and see what happens? Problem solved.
