课时作业(十三)　Unit 1　Food matters 一、阅读理解 A (2022·湖南省长沙市长郡中学二模)Can snacking be a key element of a healthy lifestyle? If your first response is “No！”， here’s a chance to update your opinions. Some of us were raised with the advice of “Never eat between meals”， which can protect our teeth from sweets. Yet there can be significant advantages of snacking on healthy foods. Researchers have found that eating frequent mini­meals offers health benefits. Dr. David Jenkins and colleagues at the University of Toronto have reported some remarkable advantages. In one study, participants were randomly divided into two groups and both groups were given the same type and amount of food over a two­week period. One group consumed three meals a day. For those having a “Nibbling Diet”， food was divided into 17 mini­meals a day. After two weeks, the nibblers had reduced their blood cholesterol (胆固醇) levels by more than 15 percent. Cortisol (皮质醇), a stress indicator, was reduced by 17 percent. Average serum insulin (血清胰岛素) levels of nibblers were reduced by 28 percent. With less insulin, the body is less likely to convert loads of calories into body fat. Also, you may think eating concentrated sources of fat or sugar (or both) will pack the weight into your body. However, see below for some examples of healthy snacks: Nuts are high in fat so keep portions moderate. However, the fat comes with a wealth of minerals and protective substances. For growing youngsters, high­energy adults, athletes and those who have difficulty maintaining their weight, nuts are a great solution. Dried fruits (raisins, currants, apricots) help you stock up on iron. If you tend to feel cold in winter, keep raisins handy. When your blood sugar drops, you’ll have an instant remedy. Fresh fruit is also a great choice. 1．Why does the author propose a question at the beginning of the passage? A．To raise the readers’ awareness of refusing snacks.
