Packed lunches and secondary school food contain most calories as rising food costs begin to bite
Public health experts have called for an urgent cap on ultra-processed food at schools after research found the products made up nearly two-thirds of the average UK school lunch.
Across primary and secondary schools, ultra-processed food accounted for 64% of calories provided by lunchtime meals, the study found, with packed lunches typically containing more of the foods than meals provided by schools themselves.
