Vending machines (自动售货机) stocked with unhealthy snacks in leisure centres run the risk of fuelling children's being overweight, warn experts. Crisps and chocolate are on sale where children exercise despite being banned from schools and children's TV, the British Heart Foundation found (BHF). And children's meals on offer at the 35 places spot-checked were dominated by chips, sausages and burgers. The charity wants stricter regulation over the food choices available. The report, which was prepared by the Food Commission, looked at leisure centres, bowling buildings, ice skating areas and park cafes. The average calorie (卡路里) content of vending machine snacks was 203 calories, which would take a seven-year-old 88 minutes of swimming to use up. Fresh fruit was displayed at less than half of the places visited, and nutritional (营养的) information was displayed at just two of the places visited. The BHF said this severely limits the children's and parents' ability to assess the nutritional values of the products they are buying. The charity is now calling for public and private sector providers to lead the way in ensuring healthy food options are available and easily identifiable. It says it should be made a requirement that vending machines in publicly owned facilities are stocked with healthier products. A Department of Health spokeswoman said, "We are fully committed to encouraging the adoption of healthy vending machines across the country and expect local authorities to make sure there are healthy food options available in their leisure centres." Dessert, crisps and sugary drinks with bubbles of gas have been banned from all school vending machines in England since September 2007. Judy Hargadon, chief executive of the School Food Trust, said, "Convenience doesn't have to mean unhealthy." Many schools are using vending to offer pupils extra choice and independence whilst still keeping their options well-balanced and consistent.1.
