The Food Standards Agency has handed over its final nutrient profiling model to media watchdog Ofcom.

The model provides a tool for categorising foods on the basis of nutrient content and has been designed to support Ofcom in reducing the amount of junk food advertising directed at children.

Deirdre Hutton, chair of the FSA, said: “We are confident that this model provides a sound and robust basis for Ofcom to use in its work.”

Meanwhile, researchers from the US Institute of Medicine claim that they have found “strong evidence” of a link between advertising influences and purchase requests in children aged between two and 11.

The researchers are now calling on Congress to introduce legislation to ban junk food advertising aimed at children.
