Sainsbury's and other supermarkets were called upon at the Labour Party conference to do more to promote healthy eating than simply donating sports equipment.

James Clark, public affairs manager for Sainsbury's, highlighted the work the supermarket was doing with its Active Kids campaign, providing sports equipment to schools, as well as spending £7m on promoting healthy food.

However, Jane Landon, deputy chief executive of the National Heart Forum, said it was not enough.

"These initiatives from the food industry investing in support for physical education is great but I'm looking at the food industry to do what only it can do and that's to look at what it puts in food and how it markets it. Other organisations can fund equipment - only the industry can change food."
