The turkey twizzler is long gone from school dinner plates - but children on packed lunches are still eating junk.
British children eat 5.5 billion packed lunches each year but research from the University of Leeds shows that only one per cent of their lunchboxes meet the nutritional standards which have been set for their classmates on school meals.
About half of all children in England take a packed lunch to school. In the first study of its kind, the Leeds research team, commissioned by the Food Standards Agency, found that 82 per cent of their lunchboxes contained foods high in saturated fat, salt and sugar - items such as crisps, sweets and biscuits. Only one in five packed lunches contained any vegetables or salad and about half included an item of fruit - yet in the overwhelming majority of cases, even these fell well below the standards demanded of school dinners.
School meal standards were introduced in 2006 due to growing evidence linking poor health in adults with obesity or poor diet in childhood. They limit the amount of foods high in salt, sugars and fats which can be served and stipulate that school meals must provide a third of the daily requirement of every nutrient for health. And though schools watchdog Ofsted says schools must have a policy on packed lunches, there is no legislative imperative for them to comply with the same nutritional standards that are applied in the canteen.
The research was led by Charlotte Evans of the Leeds Institute of Genetics, Health and Therapeutics who said: "The lack of equivalent food standards for packed lunches gives cause for concern that they will continue to lag behind the nutritional quality of school meals."
Even without legislation, there is plenty that schools, parents and manufacturers can do to improve the situation, as Ms Evans explained: "Our research has shown that some small steps in the right direction would make a big difference. Even if schools had a policy to provide water for children eating packed lunches, this would significantly reduce their sugar intake from sweetened drinks.
"It is important that schools support health promotion programmes and strategies are in place to help parents meet nutritional standards, by encouraging them to include healthy foods such as protein-rich sandwiches and fruit and vegetables. Simply concentrating on restricting the junk content of lunch boxes can be counter-productive - children at schools where crisps are restricted, for example, end up with lunch boxes containing more confectionery.
Ms Evans added: "We also need food manufacturers to offer better choices than the traditional high salt, high sugar products that busy families rely on to fill the school lunchbox on a daily basis."
Professor Janet Cade, head of the Nutritional Epidemiology Group at Leeds added: "While we absolutely understand that many children prefer to take packed lunches to school, it is clear that they are not getting the same benefit from their midday meal as their classmates on school dinners. The poor quality of these meals could have serious implications for levels of childhood obesity and its long-term consequences."
