Flogging a dead horse – anti-fluoridationists lose in court again

Ken Perrott Sep 28, 2016

The NZ Court of Appeal has rejected the latest legal attempt by New Zealand anti-fluoridation campaigners to hinder community water fluoridation. This certificate should be awarded to New Health NZ, the NZ Health Trust and the anti-fluoridation movement for not knowing when to give up on the “fluoridation is medicine” myth. You can read a summary of … Read More

Dissecting pseudoscientific and political propaganda

Ken Perrott Sep 09, 2016

Tactics used in anti-science and pseudoscience propaganda are essentially the same as used in political propaganda. Everyone has their own ideological and political starting points – and none of us are really rational, even when we think we are. So we shouldn’t be surprised to find we are fully  in agreement with some people on one issue but on the opposite sides … Read More

An anti-fluoride trick: Impressing the naive with citations

Ken Perrott Sep 04, 2016

Some of the over 140 references in Geoff Pain’s article. These references impress some people but are irrelevant to Pain’s arguments. One way to make an article look impressive is to use citations – the more you use, the more impressive. Well, so some people think. Again and again I find anti-fluoridation campaigners refer to the number of references in … Read More

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

August ’16 – NZ blogs sitemeter ranking

Ken Perrott Sep 02, 2016

There are about 300 blogs on the list, although I am weeding out those which are no longer active or have removed public access to sitemeters. (Let me know if I weed out yours by mistake or get your stats wrong). Every month I get queries from people wanting their own blog included. I encourage and am happy to respond to queries … 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
