The sim

4、ple explanation is that we eat too much junk food and spend too much time in front of screens be they television, phone or computer to burn off all those empty calories. One handy prescription for healthier lives is behavior modification. If people only ate more fresh produce. If only children exerc

5、ised more. Unfortunately, behavior changes wont work on their own without huge societal shifts, health experts say, because eating too much and exercising too little are merely symptoms of a much larger disease. The real problem is a landscape littered with inexpensive fast-food meals; much advertis

6、ing for fatty, sugary products; inner cities that lack supermarkets) and unhealthy, high-stress workplaces. In other words, its the environment. “Everyone knows that you shouldnt eat junk food and you should exercise,“ says Kelly D. Brownell, the director of the Rudd Center for Food Policy and Obesi

7、ty at Yale. “But the environment makes it so difficult that fewer people can do these things, and then you have a public health catastrophe.“ Dr. Brownell, who has a doctorate in psychology, is among a number of leading researchers who are proposing large-scale changes to food pricing, advertising a

8、nd availability, all in the hope of creating an environment favorable to healthier diet and exercise choices. To that end, health researchers are grappling with how to fix systems that are the root causes of obesity, says Dee W. Edington, the director of the Health Management Research Center at the

9、University of Michigan. “If you take a changed person and put them in the same environment, they are going to go back to the old behaviors,“ says Dr. Edington, who has a doctorate in physical education. “If you change the culture and the environment first, then you can go back into a healthy environ

10、ment and, when you get change, it sticks. “ Indeed, despite individual efforts by some states to tax soda pop, promote farm stands, require healthier school lunches or order calorie information in chain restaurants, obesity rates in the United States are growing. An estimated 72. 5 million adults in

11、 the United States are obese, according to the Centers for Disease Control and Prevention. Last year, about 27 percent of adults said they were obese, compared with about 20 percent in 2000, as reported in a C. D. C. study published this month. And, the report said, obesity may cost the medical syst

12、em as much as $ 147 billion annually. Equalizing food price So what kind of changes might help nudge (促使 ) Americans into healthier routines? Equalizing food pricing, for one. Fast-food restaurants can charge lower prices for value meals of hamburgers and French fries than for salad because the gove

13、rnment subsidizes the corn and soybeans used for animal feed and vegetable oil, says Barry Popkin, a professor of nutrition at the Gillings School of Public Health at the University of North Carolina at Chapel Hill. “We have made it more expensive to eat healthy in a very big way,“ says Dr. Popkin,

14、who has a doctorate in agricultural economics and is the author of a book called The World Is Fat -. The Fads, Trends, Policies and Products That Are Fattening the Human Race. The inflation-adjusted price of a McDonalds quarter-pounder with cheese, for example, fell 5. 44 percent from 1990 to 2007,

15、according to an article on the economics of child obesity published in the journal Health Affairs. But the inflation-adjusted price of fruit and vegetables, which are not subject to federal largess (赠与 ), rose 17 percent just from 1997 to 2003, the study said. Cutting agricultural subsidies would ha

16、ve a big impact on peoples eating habits, says Dr. Popkin. “If we cut the subsidy on whole milk and made it cheaper only to drink low-fat milk,“ he says, “people would switch to it and it would save a lot of calories.“ Company keeping employees from obesity Health experts are also looking to the pri

17、vate sector. On-site fitness centres and vending machines that sell good-for-you snacks are practical workplace innovations that many companies have instituted. On a more philosophical level, innovative companies are training managers not to burn out employees by overworking them, says Dr. Edington

18、of the University of Michigan. “Stress comes up. It can lead to overeating and obesity,“ Dr. Edington says. At companies that see employee health as a renewable resource, he adds, managers encourage employees to go home on time so they can spend more time with their families, communities or favorite

19、 activities. “Instead of going home with an empty tank, you can go home with the energy that we gave you by the way we run our business,“ he says. Corporate-sector efforts arent entirely altruistic (无私心的 ). Its less expensive for businesses to keep healthy workers healthy than to cover the medical c

20、osts of obesity and related problems like diabetes (糖尿病 ). For employees at IBM and their families, for example, the annual medical claim for an obese adult or child costs about double that of a non-obese adult or child, says Martin J. Sepulveda, IBMs vice president for integrated health services. I

21、BM has been promoting wellness for employees since the 1980s. But in 2008, it began offering a new program, the Childrens Health Rebate, to encourage employees to increase their at-home family dinners, their servings of fruits and vegetables, and their physical activities, as well as to reduce their

22、 childrens television and computer time. In addition to helping prevent obesity in children, Mr. Sepulveda says, the program is aimed at employees who might neglect to exercise on their own but would willingly participate as part of a family project. Each family that completes the program receives $

23、 150. Britain launching an attack concerning obesity All of these ideas sound promising. But the architecture of obesity is so entrenched (难以更改的 ) that policy makers, companies, communities, families and individuals will need to undertake a variety of efforts to displace and replace it, says Alan Ly

24、les, a professor at the School of Health and Human Services at the University of Baltimore. And American efforts can seem piecemeal compared with those in Britain, where the government has undertaken an allround national attack, requiring changes in schools, health services and the food industry. Br

25、itain now places restrictions on advertising fatty, sugary and salty foods during childrens shows, for example. And by 2011, cooking classes will be mandatory (强制性的 ) for all 11- to 14-year-old students in the nation. The hope is to teach a generation of children who grew up on prepared foods how to
