The European food safety authority has told dairy Group Campina it cannot claim that the extra calcium added to its fruit juices counteracts the erosion of tooth enamel, the Financieele Dagblad reports.

The Efsa said in its ruling that reducing enamel erosion should also lead to a reduction in the risk of tooth decay but none of the 37 studies submitted by Campina proved this.
Campina said the decision would not have any serious consequences because the claim had not yet been put on the market. The company is preparing to submit a revised proposal.
The Efsa has previously rejected anti-diarrhoea claims from the makers of Actimel yoghurt drink and a Unilever claim that drinking its black tea led to an increase in mental sharpness, the paper says.
