Head teachers are to consider banning packed lunches and preventing pupils from leaving school premises during breaks to buy junk food as part of plans to promote healthy eating.
Leon owners Henry Dimbleby and John Vincent have delivered their School Food Plan to the Department of Education with a raft of suggestions for increasing school lunch take-up beyond the current figure of 43%.
The report found that parents spend almost £1b a year on packed lunches, but that only 1% of those lunches were nutritionally balanced. It suggested that improved nutrition would lead to better academic results.
Among the proposals are a ban on unhealthy packed lunches, the provision of subsidised school meals, cashless payments to reduce queues, and the inclusion of cooking on the curriculum until children are 14.
Dimbleby said matters had improved since Jamie Oliver's campaign against the Turkey Twizzler, but that take-up of school meals was still too low.
"The best schools find ways of making packed lunches the least exciting option."
