The Tweenies are very popular worldwide

BBC Worldwide, the corporation's commercial arm, was criticised by the Food Commission for using the popular children's TV characters to promote food which it says is high in either salt, sugar or fat.

Parents complained via the independent watchdog, which campaigns for healthier, safer food in the UK.

One mother from London complained on the Food Commission website: "Surely the BBC could target more healthy products for the Tweenies to promote, as being 'cool' for kids to consume."

A BBC Worldwide spokeswoman said there would be no more fast food promotions involving children's TV characters.

"The Tweenies joint promotion with McDonalds ended on 4 July and we have no plans for further joint promotions with fast food restaurants for BBC children's programmes to which BBC Worldwide owns the rights," she said.

"BBC Worldwide recognises the concern over health issues surrounding children's food items and we are currently undertaking a general review of our food licensing policy."

McDonald's had a recent 11% jump in sales

But some "treat foods" would still be branded with BBC children's programmes, she added.

"BBC children's characters are not only about learning but are also about fun and entertainment.

"We work with nutritionists to provide a wide range of items that contribute to a child's diet, ranging from healthy options such as yoghurt, dried fruit, and organic pasta to items which are intended to be occasional treats."

She added BBC Worldwide was always looking for ways of making food used in joint promotions more healthy and its food policy is constantly assessed in the light of nutritional guidelines.

The recipe of Tweenies, Fimbles and Teletubbies Pasta Shapes is being redeveloped to reduce the salt content.

A spokesperson for McDonald's was unavailable for comment.

The fast food chain recently introduced healthier options to its menu, including salads.

Tweenies, which chronicles the adventures of Bella, Milo, Fizz and Jake, has been sold to nearly 50 countries, including the USA, and has been translated into 30 languages.

It has become a huge money-spinner for BBC Worldwide since the show began in 1999.
