问题                         America’s New Dietary Advice
    Trying to get Americans to eat a healthy diet is a frustrating business. Even the best-designed public-health campaigns cannot seem to compete with the tempting flavours of the snack-food and fast-food industries and their fat-and sugar-loaded products. The results are apparent on a walk down any American street—more than 60 % of Americans are overweight, and a full quarter of them are overweight to the point of obesity.
    Now, health advocates say, an ill-conceived redesign has taken one of the more successful publichealth campaigns—the Food Guide Pyramid—and rendered it confusing to the point of uselessness. Some of these critics worry that America’s Department of Agriculture caved in to pressure from parts of the food industry anxious to protect their products.
    The Food Guide Pyramid was a graphic which emphasizes that a healthy diet is built on a base of grains, vegetables and fruits, followed by ever-decreasing amounts of dairy products, meat, sweets and oils. The agriculture department launched the pyramid in 1992 to replace its previous programme, which was centred on the idea of four basic food groups. The " Basic Four" campaign showed a plate divided into quarters, and seemed to imply that meat and dairy products should make up half of a healthy diet, with grains, fruits and vegetables making up the other half. It was replaced only over the strenuous objections of the meat and dairy industries.
    The old pyramid was undoubtedly imperfect. It failed to distinguish between a doughnut and a whole-grain roll, or a hamburger and a skinless chicken breast, and it did not make clear exactly how much of each foodstuff to eat. It did, however, manage to convey the basic idea of proper proportions in an easily understandable way. The new pyramid, called "My Pyramid", has been simplified to a mere logo. The food groups are replaced with unlabelled, multicoloured vertical stripes. Anyone who wants to see how this translates into a healthy diet is invited to go to a website, put in their age, sex and activity level, and get a custom-designed pyramid, complete with healthy food choices and suggested portion sizes. This is fine for those who are motivated, but might prove too much effort for those who most need such information.
    Admittedly, the designers of the new pyramid had a tough job to do. They were supposed to condense the advice in the 84-page United States’ Dietary Guidelines into a simple, meaningful graphic suitable for printing on the back pf a cereal box. Nevertheless, many health advocates believe the new graphic is a missed opportunity. On the other hand, it is not clear how much good even the best graphic could do. Surveys found that 80% of Americans recognized the old Food Guide Pyramid—a big success in the world of public-health campaigns. Yet only 16% followed its advice.
Which of the following can help to recommend the proportion of food for individuals?

选项 A、Basic Four.
B、The Food Guide Pyramid.
C、My Pyramid.
D、United States’Dietary Guidelines.

答案C

解析 本题考查综合事实细节。根据第四段的介绍可知,“我的金字塔”虽然只是一个标志,但它引导人们访问网站,得到符合个人情况的定制的膳食图表,因此[C]为正确项。[A]和[B]都只是显示了食物大概的比例,无法针对个人情况。[D]在第五段出现,其具体内容文中没有提及,因此无法推知它是否可以针对个人推荐食物比例,排除[D]。
