Protection of teeth by fluoride confirmed – yet again - Open Parachute

Ken Perrott Nov 26, 2018

The protective role of fluoride in teeth has been confirmed, yet again. A new study nicely demonstrates how incorporation of even a small amount of fluoride into the surface layer of teeth protects them from the acid attack which leads to tooth decay. Researchers measured the ablation, or loss of surface material from hydroxyapatite before fluoridation and after fluoridation. It … Read More

A more convincing take on prenatal maternal dietary effects on child IQ - Open Parachute

Ken Perrott Sep 17, 2018

Prenatal maternal nutrition is more likely to influence child cognitive abilities than fluoride. A new paper shows this by considering the effects of good or bad prenatal nutrition for the women in the Basash et al., (2016)  study that anti-fluoride campaigners promote. The new data shows that nutrition is more important than fluoride. The Bashash et al. (2016) reported a … Read More

Anti-fluoride campaigners exhaust their legal channels with another loss - Open Parachute

Ken Perrott Jun 28, 2018

The NZ Supreme Court has delivered its judgments and local anti-fluoride campaigners (and their big business supporters) seem to have come to the end of the line with their legal actions to prevent community water fluoridation (see Supreme Court rules against Taranaki anti-fluoride campaigners and Supreme Court rules South Taranaki fluoridation allowed). Specifically, the Supreme Court delivered two judgments rejecting … Read More

Anti-fluoridationists rejection of IQ studies in fluoridated area. - Open Parachute

Ken Perrott Apr 04, 2018

US anti-fluoride activist Paul Connett claims studies cannot detect an IQ effect from fluoridated water because total fluoride intake is the real problem – but still campaigns against community water fluoridation. Image credit: MSoF “Activist Spouts Nonsense – The Evidence Supports Fluoridation” This is another article in my critique of the presentation Paul Connett prepared to present to a … Read More

The 52 IQ studies used by anti-fluoride campaigners - Open Parachute

Ken Perrott Mar 28, 2018

Slide number 30 from Paul Connett presentation prepared for a talk at NZ Parliament buildings in February 2018. Continuing my critique of the presentation prepared by Paul Connett for his much-publicised meeting at Parliament Building in February.

Why is it so difficult to get an open discussion on fluoridation? - Open Parachute

Ken Perrott Mar 22, 2018

Yes, I know – everyone’s mind is already made up so participants just talk past each other. People’s positions on this and similar issues have become a matter of identity – people are driven by emotions, not information. But, the information is there – and while I agree many people are driven by emotions they often attempt to use that information to … Read More
