A more convincing take on prenatal maternal dietary effects on child IQ

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

Fluoridation: “debating” the science?

Ken Perrott Sep 11, 2018

New Zealand last week saw another “debate challenge” from anti-fluoride activists. But are their regular challenges serious? And do gladiatorial “debates” before partisan audiences have any value in science anyway? These people often back away when their bluff is called.

Who is weaponising the vaccination debate?

Ken Perrott Aug 29, 2018

The media are promoting a new scientific paper on the vaccination debate. Their interest is undoubtedly driven by the study’s conclusion that “Russian trolls” (and by implication the Russian state) are amplifying this debate to promote discord in the US. The title describes this as “Weaponization of Health Communication.” I am very cynical. After all, the media loves to dramatise … Read More

Ken Perrott Aug 08, 2018

Official investigations contaminated by political pressure are hardly likely to be transparent or give rational answers to problems. Once politics is in the driving seat, the political aims become the driving force behind any conclusions. The “novichok” poisonings Many people see this as the basic problem with the investigation of the nerve agent poisonings in Salisbury and Amesbury, UK. Political … Read More

Anti-fluoride campaigners exhaust their legal channels with another loss

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
