UK's Department of Health has announced a new health scheme to tackle the country's soaring obesity rates. The government is now cooperating with 17 food companies, including Coca-Cola, Subway and Tesco to bring down the calories of their foods. 　　Under the new plan, Coca-Cola in the UK will introduce a 30% reduction of calories in some of its soft drinks by 2014. Mars, the chocolate bar maker, will have to set a cap of 250 calories, while many of the chocolate makers need to use re-sealable packaging on their products. In addition, some of the supermarkets will need to develop a new low-calorie brand. 　　As part of the government's "Public Health Responsibility Deal," the scheme aims at cutting five billion calories from people's diet. Health Secretary Andrew Lansley says that more than three-quarters of the retail market has signed up, and "is a great step in the right direction and will help millions of British people eat and drink fewer calories." 　　However, some people question the effectiveness of the plan, saying that it's to the government's disgrace that the food industry is actually helping to set government health policy. They believe that better food labeling and shielding children from advertisement for junk food should be the starting point for a healthier diet.
