ADHD link to fluoridation claim undermined again Ken Perrott Apr 21

Recently I suggested that Attention Deficit Hyperactivity Disorder (ADHD) was better correlated with elevation than with community water fluoridation (see ADHD linked to elevation not fluoridation). I criticised the study of Malin and Till (2015) for limiting their investigation to a chemical toxicity hypothesis and pointed out that once confounding factors like elevation are included their reported relationship … … Continue reading

Commercial and ideological support of anti-fluoride activity Ken Perrott Apr 19

Fluoride Free NZ (FFNZ) promotes a list of “NZ Health Professionals who are calling for an end to fluoridation.” I am generally cynical about such endorsement lists, but the details in this list do give a picture of the commercial and ideological alignment of the FFNZ supporters and activists.

Sometimes they will even do their own “research”  using published and on-line health data looking for any correlations with CWF, or even just with fluoride levels … … Continue reading

IQ not influenced by water fluoridation Ken Perrott Apr 08

That is what the US data for average state IQ and percent water fluoridation tells us. I thought I would check out the US IQ and fluoridation data for each state after reading Malin and Till (2015). That paper compared the prevalence of ADHD by state with the percent fluoridation in each state. There are … … Continue reading

Making sense of scientific research Ken Perrott Apr 06

(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 … … Continue reading
