Once again the food industry is under attack from campaigner who claim that brands are targeting children, this time through online advertising.

A report by the British Heart Foundation has claimed that websites from companies such as Cadbury’s or Nestle, use childish language, games and free gifts to appeal to children, as an alternative to TV advertising, which has become all more restricted.

The report highlights the use of cartoon characters on social networking sites as another attraction to children.

Betty McBride, director of policy for the BHF, said: “These products are not allowed to be advertised during children’s television because we know that advertising influences food choices.

“Yet online, children are being bombarded by promotions for foods and drinks high in fat, sugar and salt.”

A spokesperson for the Advertising Standards Authority has said that it ‘rigorously’ policed food adverting across media, including online.
