Does community water fluoridation reduce diabetes prevalence?

Ken Perrott Sep 04, 2016

You will be seeing headlines claiming a link between community water fluoridation (CWF) and diabetes. Or even that fluoridation can predict an increase in the prevalence of diabetes. But they are misleading These articles report results from a recently published study indicating that in the majority of situations CWF is linked to a decrease in diabetes prevalence. But many of these articles, and … Read More

‘Filtering’ out fluoride

Ken Perrott Sep 03, 2016

Many anti-fluoride campaigners and their sympathisers use “filters” to remove fluoride from their tap water. Despite this, they will often claim the procedure is “too expensive” for the ordinary person – or that it is ineffective. Fluoride Free Nelson (FFN) combined both reasons in this exchange on their Facebook page. But she is wrong on both counts. Suitable … Read More

Fluoridation – freedom of choice

Ken Perrott Sep 02, 2016

This sort of image springs to mind when I see claims of forced fluoridation. Aren’t activists like “Forced Fluoridation Freedom Fighters” misrepresenting the real situation? I think the “freedom of choice” argument is the most reasonable argument that anti-fluoride campaigners can use. Unfortunately for them, they usually only resort to it after their “science-based” arguments have been exposed as misleading … Read More

Is water fluoridation better than salt fluoridation?

Ken Perrott Aug 09, 2016

Discussion of fluoridation here concentrates on community water fluoridation. But some countries (parts of Europe, and Latin America, for example) fluoridate their salt instead of their water.  This could be for a number of reasons – the state of the water reticulation system, or political opposition to water fluoridation, etc. The effectiveness of community water fluoridation in reducing tooth decay is well established … Read More

Ethics and the doping scandal – a response

Ken Perrott Aug 07, 2016

International Olympic Committee (IOC) decisions about participation of athletes from the Russian Federation in the Rio Olympics have brought both criticism and support – from the political as well as the sporting communities. The issues of sports doping, the responsibilities and actions of sporting bodies and the political context and factors all need discussing. So I am pleased to see … Read More

Being better informed – unexpected advice from The Guardian

Ken Perrott Aug 03, 2016

This opinion piece by Piers Robinson in The Guardian surprised me – and then it pleased me – Russian news may be biased – but so is much western media. Surprised me because, of late, The Guardian has been shockingly one-sided. Particularly in its treatment of Russian politics, nationally and internationally. Unfortunately doesn’t include any self criticisms – that would have … Read More

Dental health – it’s not all about fluoride

Ken Perrott Jul 26, 2016

Fluoride is not the only factor in oral health. But it is generally the only element in drinking water considered for its effect on our teeth. Drinking water fluoride benefits existing teeth by chemically reacting with the tooth surface. Involvement of fluoride in the apatite structure at the tooth surface helps prevent demineralisation, due to acid attack, and also encourages remineralisation – … Read More

Two years on and there has yet to be a a decision on who was responsible for shooting down Malaysian Airlines MH17 over Eastern Ukraine.   This video shows the local memorial meeting held near the crash site.
