The UK government has announced a major overhaul of school food standards in England, effective immediately, which will see fried nuggets and steamed sponges removed from menus in a bid to tackle rising obesity rates among children.

The new rules mark the first update to school food standards in 13 years and have been welcomed by campaigners who have long argued that the existing standards were not doing enough to promote healthy eating habits among schoolchildren. The updated standards will see a significant reduction in the amount of fried and processed foods served in schools, with a greater emphasis on fresh fruit and vegetables, whole grains, and lean proteins. The move is expected to have a major impact on the diets of millions of schoolchildren in England, with many schools having relied heavily on convenience foods such as nuggets and chips.

The overhaul of school food standards is part of a wider effort to tackle the growing problem of childhood obesity in England, which has become a major public health concern in recent years. Obesity rates among children in England are among the highest in Europe, with nearly a third of children aged between two and 15 classed as overweight or obese. The new standards are designed to help children develop healthy eating habits from a young age, with the aim of reducing the risk of obesity and related health problems such as diabetes and heart disease. The move is also expected to have a positive impact on children's concentration and behaviour in the classroom, with a healthy diet having been shown to improve cognitive function and mood.

The reaction to the announcement has been largely positive, with campaigners and health experts welcoming the move as a major step forward in the fight against childhood obesity. The new standards are expected to come into force in the autumn, with schools given a period of time to adjust their menus and sourcing arrangements. The government has also announced plans to provide additional support and funding to schools to help them implement the new standards, including training for catering staff and funding for new kitchen equipment. The move is seen as a key part of the government's efforts to improve public health and reduce the burden on the NHS, with obesity-related illnesses estimated to cost the health service billions of pounds each year.
