Imagine eating everything delicious you want with none of the fat. That would be great, wouldn’t it?
New "fake fat" products appeared on store shelves in the United States recently, but not everyone is happy about it. Makers of the products, which contain a compound called olestra, say food manufacturers can now eliminate fat from certain foods, Critics, however, say that the new compound can rob the body of essential vitamins and nutrients and can also cause unpleasant side effects in some people. So it is up to consumers to decide whether the new fat-free products taste good enough to keep eating.
Chemists discovered olestra in the late 1960s, when they were searching for a fat that could be digested by infants more easily. Instead of finding the desired fat, the researchers created a fat that can’t be digested at all.
Normally, special chemicals in the intestines "grab" molecules of regular fat and break them down so they can be used by the body. A molecule of regular fat is made up of three molecules of substances called fatty acids.
The fatty acids are absorbed by the intestines and bring with them the essential vitamins A, D, E and K. When fat molecules are present in the intestines with any of those vitamins, the vitamins attach to the molecules and are carried into the bloodstream.
Olestra, which is made from six to eight molecules of fatty acids, is too large for the intestines to absorb. It just slides through the intestines without being broken down. Manufacturers say it’s that ability to slide unchanged through the intestines that makes olestra so valuable as a fat substitute. It provides consumers with the taste of regular fat without any bad effects on the body. But critics say olestra can prevent vitamins A, D, E, and K from being absorbed. It can also prevent the absorption of carotenoids, compounds that may reduce the risk of cancer, heart disease, etc.
Manufacturers are adding vitamins A, D, E and K as well as carotenoids to their products now. Even so, some nutritionists are still concerned that people might eat unlimited amounts of food made with the fat substitute without worrying about how many calories they are consuming. [br] What is a possible effect of olestra according to some critics?
选项
A、It may impair the digestive system.
B、It may affect the overall fat intake.
C、It may increase the risk of cancer.
D、It may spoil the consumers’ appetite.
答案
C
解析
细节推断题。根据题干关键词some critics定位到原文第六段末尾两句。olestra阻止人体吸收carotenoids(类胡萝卜素),而类胡萝卜素能reduce the risk of cancer。故答案为C。
