"Fluoride linked to weight gain and depression"

Articles in The Daily Telegraph on 24th February 2015 and Daily Mail on 25th February 2015 reported that fluoride in water supplies could be causing thyroid problems leading to weight gain and depression. In fact the study, published in the Journal of Epidemiology & Community Health, cannot be used to conclude that fluoride causes thyroid problems.

 British Dental Association:

“It is an interesting study though we agree with the authors that no definitive conclusions can be drawn about cause and effect. There may be other factors at play, particularly iodine levels in the water, which would have to be taken into account before any certain scientific conclusions could be drawn.”

Public Health England:

“Public Health England regularly reviews the evidence base for water fluoridation. The totality of evidence, accumulated over decades of research, tells us that water fluoridation is a safe and effective public health measure, and shows no association with reduced thyroid function. PHE’s own assessment of water fluoridation programmes in England found evidence of lower tooth decay rates in children living in fluoridated compared to non-fluoridated areas, and greater reductions among those living in the most deprived areas.”
