Eating healthily costs about $1.50 more per person daily, according to the most thorough review yet of the affordability of a healthy diet.
"For many low-income families, an【C1】________$1.50 daily is quite a lot," says Mayuree Rao, "It【C2】________to about $550 more per year per person, and that could be a real【C3】________to healthy eating."
Rao and her colleagues reached their【C4】________after analysing 27 studies from 10 high-income countries, comparing price【C5】________for healthy versus unhealthy ingredients and diets.【C6】________one study compared the cost of a diet rich in fruit and vegetables versus one that was【C7】________in them. Another compared prices of【C8】________healthy and less healthy items, such as wholegrain versus white bread.
Individual items were【C9】________matched in price. Meats【C10】________the largest difference: healthier options cost an average of 29 cents per serving more than unhealthy options.
【C11】________this, comparisons of whole diets showed that healthier diets cost averagely $1.48 more per day.
This shows that comparisons based on single ingredients don’t tell the full【C12】________. "It tells us that,【C13】________, it doesn’t cost more to eat healthier based on one nutrient," says Rao. "But there’s growing evidence that the【C14】________of foods in your diet【C15】________your disease risk more than any single nutrient, so we think our【C16】________finding that healthier diets cost about $1.50 more has the most public health【C17】________."
As to why healthier food has become more【C18】________Rao says that it may be because the food industry organizes itself and the types of food it produces to【C19】________its own economies of scale,【C20】________than what’s best for consumers.
【C18】
选项
A、expensive
B、popular
C、affordable
D、superior
答案
A
解析
上文通过比较健康和不健康的食物成分和饮食的价格差异得出的结论是:健康的饮食和食物更贵。从空格所在句的why特殊疑问句和后面的economies of scale“规模经济”(规模经济的最大优势是降低成本)。可推断该句是进而分析健康的饮食和食物更贵的原因,所以选A项expensive。文章没有提到健康食品是否受欢迎,可排除B项popular。文章比较分析的结果是健康的饮食和食品比不健康的饮食和食品更贵,所以C项affordable“负担得起的”跟上文语义相反,故排除。D项superior本身已含“较好”的意思。所以不需再用more修饰。
