根据短文内容,从短文后的七个选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。Which is healthier a bag of crisps or a vegetable salad? That is easy. Now which is healthier: a pizza made from scratch or one made from the same basic ingredients, with the same number of calories, pulled out of a box in the freezer? Many people would instinctively (本能的) say the former, perhaps showing a vague concern with processed food. Such food can often be delicious. And there is much to cheer about calories being cheap and abundant. What's the distinction between "ultra-processed food (upf)" and "processed food"? Almost everything people consume is processed in some form. Rice is harvested; animals are butchered. Upf is usually described as "formulations of ingredients, made by a series of industrial processes, many requiring advanced equipment and technology". The one in the freezer, with its extra, modified ingredients, is upf.Upf harms people in ways both known and unknown. It seems to affect the trillions of bacteria that contribute to health in a range of ways. Calorie-rich but usually nutrient-poor, upf contributes to obesity (肥胖症).Upf displaces healthier alternatives, particularly for poor people. Extra weight was once a sign of wealth, but among British and American women today, obesity rates are higher at lower-income levels. Additives that may be safe in small quantities may be harmful in combination with other chemicals or when consumed regularly. If we are what we eat, considering the impact of upf is essential. People who live in so-called "food swamps", where upf is everywhere but real food is harder to reach, could spend large amounts of time and money seeking out fresh food, but that is not how most people live. There is nothing wrong with the odd fast-food trip, but anyone who can afford to eat less upf probably should.A. Environment matters, too.B. It's cheap to produce and buy.C. But that cheapness and abundance come at a cost.D. Even foods labeled "natural" or "organic" can be processed.E. A pizza made from scratch contains minimally processed food.F. Some people have a particular weakness for salty potato crisps.G. The reasons why upf can be harmful are not always clear, even to scientists.
