The advertising standards authority has not upheld complaints about two recent anti fluoride ads that aired on television.
The advertisements claimed that fluoride does not improve dental health, is a waste product collected from the chimneys of the fertiliser industry and that it contains poisons including possibly uranium.
The authority received 6 complaints, which argued that the ads contained misleading information and played on fear to get its message across.
The ads coincided with a visit to New Zealand by international anti fluoride campaigner, Paul Connett, a retired chemistry professor. Jesse asks him why he continues to fight water fluoridation when the weight of international evidence shows it is safe.
Jesse also speaks with Sir Peter Gluckman, the Prime Ministers Chief Science Advisor, who responds to criticism from Paul Connett.
