D The federal school lunch program for 30 million lowine children was created more than half a century ago to bat malnutrition(营养不良 ). A breakfast program was added during the 1960s, and both attempted to improve the nutritional value of food served at school. More must be done to fight the childhood obesity(肥胖 ) epidemic, which has caused a frightening peak in weightrelated disorders like diabetes, highblood pressure and heart disease among young people. The place to start is schools, where junk food sold outside the federal meals program— through snack bars and vending machines— has pretty much canceled out the benefits of all those efforts. Federal rules that govern the sales of these harmful foods at school are limited and have not been updated for nearly 40 years. Until new regulations are written, children who are served healthy meals in the school cafeteria will continue to buy candy drinks and high sodium(钠 ) snacks elsewhere in school. Many states’ school districts have taken positive steps, but others are likely to resist, especially districts that sell junk food to finance athletic program extracurricular activities, and even copier expenses. Those districts should take note of a study released in 2020 in West Virginia showing that the budgetary costs of switching from sodas to healthy drinks such as fruit juice, milk, and water were very little. Even if the switch costs money, so be it. The school should not be trading their students’ health to buy office supplies. Over the last five decades, the obesity rates for adolescents have tripled. Unless there is decisive action, weight and inactivityrelated disorders will bother a steady larger proportion of the work force and replace smoking as the leading cause of premature death. 32.
