Ken Perrott Oct 17, 2016

A new Swedish study confirms fluoride does not increase risks of hip fracture, myocardial infarction, or osteosarcoma. That’s the conclusion from a new Swedish study. And these conclusions agree with most findings from earlier studies. Peggy Näsman describes this new study in her PhD thesis: Epidemiological studies of fluoride exposure and hip fracture , myocardial infarction and osteosarcoma.(Näsman, P. (2016)) She used Swedish … Read More

Shyness of anti-fluoride election candidates

Ken Perrott Oct 05, 2016

Why do anti-fluoride candidates standing for District Health Boards (DHBs) shy away from proper discussion of community water fluoridation? After all, they have usually raised the issue themselves – and often claim that those supporting community water fluoridation avoid the discussion. In my article Fluoridation & democracy: Open letter to DHB candidate Andrew Buckley I raised this with Andrew Buckley who is standing for … Read More

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

‘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
