Prue Leith, the restauranteur and former British government food adviser, told the Hay Festival the idea behind the chef's campaign was praiseworthy, but a 2009 study suggested the number of children eating school meals dropped by 400,000 since 2005, The Sunday Telegraph reported.
Leith said she once checked on child's lunchbox and it contained a can of Coke, a packet of biscuits, a Kit Kat, two sets of pink-and-white sugar false teeth and another sugary treat.
Unfortunately, many parents are supplying their children with worse lunches than the schools supplied.
Oliver's work on TV and a documentary highlighted than many school lunches could have been healthier and eventually he met with Tony Blair, who was prime minister at the time, and the British government allocated $435 million over three years to invest in proper kitchens in schools, Leith said.
In addition, 1-in-4 schools having a cooking club and every child in a state school can learn to cook, but often parents do not think it is important, Leith said.
