单选题 Entire cities and counties have banned them. McDonald's and Kentucky Fried Chicken have declared to give them up-as have Starbucks, Ruby Tuesday, and a host of other former sources of sinful pleasures. In response to the 2006 Food and Drug Administration requirement that trans fats be listed on nutrition labels, makers of packaged goods have brought their totals down to zero. Last month, Frito-Lay even got the FDA's blessing to put a claim on products loaded with healthy, unsaturated fats that replacing bad fats with good ones may protect against heart disease.
Does this mean that junk food is now the new health food? "No!" says Robert Eckel. immediate past president of the American Heart Association, whose "Face the Fats" education campaign points out that a "zero trans fats" label doesn't tell the whole story. "People know trans fats are not good for them," says Eckel. "But they do not understand that replacing them with saturated fat is not a good option." And that, in some cases, is what's happening. Yes, the food industry is experimenting with ways to keep the saturated fat content low-by using unsaturated options such as canola and sunflower oils, for example. But some manufacturers, unwilling to sacrifice taste and texture, are turning back to less-than-healthful choices such as palm oil and butter.
Baked goods have proved particularly unwilling to change. The solid fats that provide their light texture and flakiness as well as the rich flavor typically are either highly saturated or are "partially hydrogenated" oils that contain trans fats. Makers of fried foods have had an easier task, since certain liquid unsaturated oils can do as tasty a job. Snack makers, too, have found the switch to be relatively manageable.
Manufacturers are raising nutrition experts' eyebrows with other tricks, too. Walter Willett, a professor of epidemiology and nutrition at Harvard whose research showed that trans fats promote heart disease, says that some companies now are fully, rather than partially, hydrogenating vegetable oil. Full hydrogenation doesn't create trans fats as it solidifies the oil, but it does produce an acid; a saturated fat which seems in preliminary research to promote inflammation, thus contributing to heart disease. "I'm not in favor of using totally hydrogenated oil until more is known," he says.
A recent study by the International Food Information Council Foundation shows that about 42 percent of Americans-a 9 percent increase over last year-are trying to cut back on certain healthy tats along with trans fats. "All people hear is that fat is bad, bad, bad," says Susan Borra, president of the foundation. In fact, most people need more of the good kind.
单选题 McDonald's and Kentucky Fried Chicken have pledged to get rid of
  • A. sinful pleasures.
  • B. trans fats.
  • C. nutritious fats.
  • D. unsaturated fats.
【正确答案】 B
【答案解析】事实细节题。根据题干中的McDonald's和Kentucky Fried Chicken定位到第一段。其中讲到麦当劳和肯德基等企业宣布停止使用不健康的反式脂肪酸,故B项正确。A项sinful pleasures张冠李戴;C项是对文中nutrition labels的曲解;D项曲解了该段末句句意,不饱和油前面的定语是healthy,它并不是企业禁用的东西。
单选题 To which of the following statements would Robert Eckel most likely agree?
  • A. "Zero trans fats" label tells that the food is healthy for sure.
  • B. Junk food is now thought of as the new health food.
  • C. It sometimes does no good to use saturated fats instead of trans ones.
  • D. People don't realize that trans fats are harmful.
【正确答案】 C
【答案解析】观点态度题。根据题干中的Robea Eckel定位到第二段。该段明确说明Robert Eckel认为用饱和脂肪代替反式脂肪并不是一个好的选择,故C项正确。A项for sure的肯定语气与文章中doesn't tell the wholestory“不能说明所有问题”相悖;在谈到现在的垃圾食品能否成为新型健康食品时,Robert Eckel明确表示否定的态度,故B不符;Robert Eckel认为人们都知道反式脂肪不好,只是不明白用饱和脂肪代替反式脂肪并不是一个好选择,因此D项歪曲事实。
单选题 According to Paragraph 3, food makers are reluctant to give up solid fats in baked goods in that
  • A. they contribute to people's health.
  • B. they are partially hydrogenated.
  • C. they are highly saturated.
  • D. they provide pleasant texture and taste.
【正确答案】 D
【答案解析】事实细节题。考查因果细节。第三段讲到固体脂肪使食品松软、口感细腻、香味浓郁,因此可以推断这就是生产商不愿放弃使用它的原因,故D项正确。A项contribute to未提及;B项“部分氢化的”、C项“高度饱和的”不能与题干构成因果关系。
单选题 When solidifying the oil, full hydrogenation might
  • A. directly lead to a certain disease.
  • B. create trans fats.
  • C. generate unsaturated fats.
  • D. contribute to fatal injury.
【正确答案】 A
【答案解析】推理判断题。根据full hydrogenation定位到第四段。该段讲述,完全氢化在使油固化时会产生一种酸,会引发炎症,从而增加患心脏病的危险,故A项与之相符。B项“产生反式脂肪”、C项“产生不饱和脂肪”与文章“完全氢化不会产生反式脂肪,但会产生一种酸,这种酸是一种饱和脂肪”相悖;D项fatal injury引申过度,原文只提到heart disease。
单选题 The last paragraph suggests that
  • A. most Americans try to reduce healthy fats and trans fats.
  • B. people should take in more healthy fats.
  • C. fat is really very bad without any benefits.
  • D. 51 percent of Americans tried less healthy fats last year.
【正确答案】 B
【答案解析】推理判断题。最后一段表明大多数人都需要摄入更多有益健康的脂肪,故B项正确。A项曲解了原文“约42%的美国人在试图减少反式脂肪的摄入时也在减少一些健康脂肪的摄入”;C项明显与文意相悖:D项是对原文“比去年增加9个百分点”的曲解。
