4、s, asparagus and arugula to fill a novel kind of prescription. Doctors at three health centers in Massachusetts have begun advising patients to eat “prescription produce“ from local farmers markets, in an effort to fight obesity (when someone is very fat in a way that is unhealthy) in children of lo

5、w-income families. Now they will give coupons (赠券 ) amounting to $1 a day for each member of a patients family to promote healthy meals. “A lot of these kids have a very limited range of fruits and vegetables that are acceptable and familiar to them. Potentially, they will try more,“ said Dr. Suki T

6、epperberg, a family physician at Codman Square Health Center in Dorchester, one of the program sites. “The goal is to get them to increase their consumption of fruit and vegetables by one serving a day.“ The effort may also help farmers markets compete with fast-food restaurants selling dollar value

7、 meals. Farmers markets do more than $1 billion in annual sales in the United States, according to the Agriculture Department. Massachusetts was one of the first states to promote these markets as hubs of preventive health. In the 1980s, for example, the state began issuing coupons for farmers marke

8、ts to low-income women who were pregnant or breast-feeding or for young children at risk for malnutrition (营养不良 ). Thirty-six states now have such farmers market nutrition programs aimed at women and young children. Thomas M. Menino, the mayor of Boston, said he believed the new childrens program, i

9、n which doctors write vegetable “prescriptions“ to be filled at farmers markets, was the first of its kind. Doctors will track participants to determine how the program affects their eating patterns and to monitor health indicators like weight and body mass index, he said. “When I go to work in the

10、morning, I see kids standing at the bus stop eating chips and drinking a soda,“ Mr. Menino said in a phone interview earlier this week. “I hope this will help them change their eating habits and lead to a healthier lifestyle.“ The mayors attention to healthy eating dates to his days as a city counci

11、lman. Most recently he has appointed a well-known chef as a food policy director to promote local foods in public schools and to foster market gardens in the city. Although obesity is a complex problem unlikely to be solved just by eating more vegetables, supporters of the vegetable coupon program h

12、ope that physician intervention will spur young people to adopt the kind of behavioral changes that can help prevent lifelong obesity. Childhood obesity in the United States costs $14.1 billion annually in direct health expenses like prescription drugs and visits to doctors and emergency rooms, acco

13、rding to a recent article on the economics of childhood obesity published in the journal Health Affairs. Treating obesity-related illness in adults costs an estimated $147 billion annually, the article said. Although the vegetable prescription pilot project is small, its supporters see it as a model

14、 for encouraging obese children and their families to increase the volume and variety of fresh produce they eat. “Can we help people in low-income areas, who shop in the center of supermarkets for low-cost empty-calorie food, to shop at farmers markets by making fruit and vegetables more affordable?

15、“ said Gus Schumacher, the chairman of Wholesome Wave, a nonprofit group in Bridgeport, Conn., that supports family farmers and community access to locally grown produce. If the pilot project is successful, Mr. Schumacher said, “farmers markets would become like a fruit and vegetable pharmacy (药房 )

16、for at-risk families.“ The pilot project plans to enroll up to 50 families of four at three health centers in Massachusetts that already have specialized childrens programs called healthy weight clinics. A foundation called CAVU, for Ceiling and Visibility Unlimited, sponsors the clinics that are ad

17、ministering the vegetable project. The Massachusetts Department of Agriculture and Wholesome Wave each contributed $10,000 in seed money. (Another arm of the program, at several health centers in Maine, is giving fresh produce coupons to pregnant mothers.) The program is to run until the end of the

18、farmers market season in late fall. One month after Leslie-Ann Ogiste, a certified nursing assistant in Boston, and her 9-year-old son, Makael Constance, received their first vegetable prescription coupons at the Codman Center, they have lost a combined four pounds, she said. A staff member at the c

19、enter told Ms. Ogiste about a farmers market that is five minutes from her apartment, she said. “It worked wonders,“ said Ms. Ogiste, who bought and prepared eggplant, cucumbers, tomatoes, summer squash, corn, bok choy, parsley, carrots and red onions. “Just the variety, it did help.“ Ms. Ogiste sai

20、d she had minced some vegetables and used them in soup, pasta sauce and rice dishes the better to disguise the new good-for-you foods that she served her son. Makael said he did not mind. “Its really good,“ he said. Some nutrition researchers said that the Massachusetts project had a good chance of

21、improving eating habits in the short term. But, they added, a vegetable prescription program in isolation may not have a long-term influence on reducing obesity. Families may revert to their former habits in the winter when the farmers markets are closed, these researchers said, or they may not be a

22、ble to afford fresh produce after the voucher program ends. Dr. Shikha Anand, the medical director of CAVUs healthy weight initiative, said the group hoped to make the veggie prescription project a year-round program through partnerships with grocery stores. But people tend to overeat junk food in h

23、igher proportion than they undereat vegetables, said Dr. Deborah A. Cohen, a senior natural scientist at the RAND Corporation. So, unless people curtail (减少 ) excessive consumption of salty and sugary snacks, she said, behavioral changes like eating more fruit and vegetables will have limited effect

24、 on obesity. In a recent study led by Dr. Cohen, for example, people in southern Louisiana typically exceeded guidelines for eating salty and sugary foods by 120 percent in the course of a day while falling short of vegetable and fruit consumption by 20 percent. The weight clinics in Massachusetts c

25、hosen for the vegetable prescription test project already encourage families to cut down on unhealthy snacks. Even as Ms. Ogiste and her son started shopping at the farmers market and eating more fresh produce, for example, they also cut back on junk food, she said. “We have stopped the snacks. We a

26、re drinking more water and less soda and less juice too,“ Ms. Ogiste said. “All of that helped.“ 2 Dr. Suki Tepperberg suggested that many overweight children_. （ A） have consumed too much meat （ B） dislike fruits and vegetables by nature （ C） mainly come from wealthy families （ D） will have more ve
