THE case for fluoride is based on politics not science, a US chemistry professor told campaigners trying to stop health chiefs adding it to the tap water of 200,000 homes.

Paul Connett, founder of the Fluoride Action Network, threw his support behind Hampshire Against Fluoridation when he spoke to members on Saturday at Southampton Solent University. He used the event to launch his new book, The Case Against Fluoride: how hazardous waste ended up in our drinking water and the bad science and powerful politics that keep it there.

Prof Connett also praised the Daily Echo’s coverage of plans by South Central Health Authority, which it claims will improve children’s teeth in Southampton, Eastleigh, Totton and Netley.

He said: “The Daily Echo’s wonderful coverage on the subject is being read across the world and it has helped educate politicians and the public. That’s why I chose to launch the book here.”
