Many people in the United States worry about not looking young and attractive. For many people, looking good also means being thin. Other people worry about their health. Many doctors say being overweight is not healthy. But are Americans really fat？
Almost 30 million Americans weigh at least 20 percent more than their ideal weight. In fact, the United States is the most overweight country in the world. "The stored fat of adult Americans weighs 2. 3 trillion pounds," says University of Massachusetts anthropologist(人类学家) George Armelagos. He says burning off that stored energy would produce enough power for 900,000 cars to go 12,000 miles.
Losing weight is hard work, but most people want to find a fast and easy way to take off fat. Bookstores sell lots of diet books. These books tell readers how to lose weight. Each year, dozens of new books like these are written. Each one boasts to help people to get rid of fat.
Which of the following is NOT mentioned as a way of losing weight？
A．To eat less fats and sugars.
B．To take much exercise.
C．To have surgery.
D．To work hard.
The growing interest of consumers in the safety and nutritional quality of the typical North American diet is a welcome development. However, much of this interest has been sparked by sweeping claims that the food supply is unsafe or inadequate in meeting nutritional needs. Although most of these claims are not supported by scientific evidence, the greater number of written material advancing such claims make it difficult for the general public to sep arate fact from fiction. As a result, claims that eating a diet consisting entirely of organically grown foods prevents or cures disease or provides other benefits to health have become widely publicized and form. the basis for folklore.
Almost daily the public is surrounded by claims for "no-aging" diets, new vitamins, and other wonder foods. There are numerous unsubstantiated reports that natural vitamins are superior to synthetic ones, that crops grown with organic fertilizers are nutritionally superior to chose with chemical fertilizers, that untreated grains are better than fumigated grains, and the like.
One thing that most organically grown food products seem to have in common is that they cost more than conventionally grown foods. But in many cases consumers are misled if they believe organic foods can maintain health and provide better nutritional quality than conventionally grown foods. So there is real cause for concern ff consumers, particularly those with limited incomes, distrust the regular food supply and buy only expensive organic foods instead.
The author implies that there is cause for concern if consumers with limit ed incomes buy organic foods instead of conventionally grown foods be cause ______ .
A．organic goods can be more expensive but are often no better than conventionally grown foods
B．many organic foods are actually less nutritious than similar conventionally grown foods
C．conventionally grown foods are more readily available than organic foods
D．too many farmers will stop using conventional methods to grow food crops
