With nearly a third of children aged 2 to 15 either overweight or obese, schools are taking greater steps to prevent childhood obesity.
More than 200 schools in Leicestershire have their meals prepared by a council-run catering service.
30,000 meals are prepared and transported across the county.
The idea is that the economy of scale will make healthy food more affordable for schools.
Croft Primary School in Leicestershire is among the schools taking part.
The council's catering service is a £13 million business.
There are now plans to expand the business elsewhere in the country - from Warwickshire and Cambridgeshire to Nottinghamshire and Derbyshire.
