Hip fractures in the elderly and fluoride – contradictory evidence

Room for cherry-picking to confirm a bias. Separate Swedish studies report that fluoride can either prevent or promote the risk of hip fracture in the elderly. Image credit: Are hip fracture patients treated quickly enough? Anti-fluoride activists are promoting a … Continue reading

An open letter to Paul Connet and the anti-fluoride movement

Paul Connett and Vyvyan Howard have, through the local Fluoride Free New Zealand activist group, published an open letter addressed to NZ scientists and educators (see An Open Letter To NZ Scientists And Educators). It is strange to encourage scientific … Continue reading

Data dredging, p-hacking and motivated discussion in anti-fluoride paper

Image credit: Quick Data Lessons: Data Dredging Oh dear – another scientific paper claiming evidence of toxic effects from fluoridation. But a critical look at the paper shows evidence of p-hacking, data dredging and motivated reasoning to derive their conclusions. And … Continue reading

Embarrassing knock-back of second draft review of possible cognitive health effects of fluoride

This is rather embarrassing for a US group attempting to get the science right about possible toxic effects of fluoride. It’s also embarrassing for the anti-fluoride activists who have “jumped the gun” and been citing the group’s draft review as … Continue reading

Even studies from endemic fluorosis areas show fluoride is not harmful at levels used in fluoridation

Anti-fluoride propagandists continually cite studies from areas of endemic fluorosis in their arguments against community water fluoridation (CWF). But if they critically looked at the data in those papers they might get a shock. Invariably the published data, even from … Continue reading

Anti-fluoride 65 brain-fluoride studies not evidence against fluoridation

Anti-fluoride and anti-vaccination activists suffer from a common activist fallacy – they believe their own propaganda. They also have a network of “natural”/alternative health industry internet sites and magazines to disseminate these beliefs and propaganda. A glaring example is a … Continue reading

Another study used by anti-fluoride activists actually shows community water fluoridation OK

Another study comparing effect in children from nonendemic areas (Dagang) and endemic fluorosis area (Jinghai) about 80km apart in the Tianjin area of China. Hardly sampling the same population. Anti-fluoride campaigners still use studies from endemic fluorosis area of China … Continue reading

When scientists get political: Lead fluoride-IQ researcher launches emotional attack on her scientific critics

It seems impossible to keep politics out of science. It’s a pity because politics can end up forcing science to produce the results desired by politicians. When this happens the ideal aim of science – the pursuit of objective knowledge … Continue reading

No relationship of bone cancer to fluoridation – another new study the anti-fluoride brigade will attempt to ignore

A new study confirms, yet again, that osteosarcoma, a type of bone cancer, is not associated with community water fluoridation (CWF). This the seventh such study since a 1990 report of an animal study suggested such a link. The 199o … Continue reading

New review finds fluoride is not a developmental neurotoxicant at exposure levels relevant to fluoridation

A new extensive review of the scientific literature has concluded that fluoride is not a human developmental neurotoxicant at the current exposure levels in Europe. This is of course just as valid for New Zealand, the USA and other countries … Continue reading
