In a strongly worded speech at the Westminster Diet and Health Forum seminar this week, CA director Sheila McKechnie said she was fed up with waiting for industry or government regulation.
"I have been warning the food industry there is a train coming down the track. We are going to spend a lot of time next year making consumers very angry indeed," she said.
McKechnie said she hoped to shift the debate in a way that would hurt the bottom line. "If your brand is important to you, do you want to associate it with things that parents think are making their children unwell?"
Food and Drink Federation director general Sylvia Jay said: "We need to do more than seek to apportion blame."
