Sugarless yoghurt could help beat bad breath, tooth decay and gum disease, say scientists. Japanese researchers found eating the yoghurt【C1】________levels of hydrogen sulphide (硫化物)— a major cause of bad breath—in 80% of volunteers. The keys are active bacteria in yoghurt.
Details were presented at a meeting of the International Association for Dental Research. A total of 24 volunteers who【C2】________in the study were given strict instructions on oral hygiene, diet and medication intake. They spent two weeks【C3】________ yoghurts and similar foods, like cheese. Researchers then【C4】________bacteria levels and odour-causing compounds, including hydrogen sulphide.
The volunteers then ate 90 grams of yoghurt a day for six weeks. At the end of the study, researchers took【C5】________ again. They found hydrogen sulphide levels decreased in 80% of participants.
Dr. Nigel Carter, chief executive of the British Dental Health Foundation, said: "The foundation has long been drawing people’s attention to sugar-free yoghurts as a【C6】________ snack, so it is pleasing to hear that it may have oral health benefits we were previously unaware of.
"Although this research is still in the early stages there is no doubt that sugar-free yoghurts【C7】________ a much healthier alternative to sweets and chocolate, and we would encourage snackers to incorporate them into their【C8】________."
However, Dr. Carter stressed that the best way to beat bad breath was by adopting a good oral health routine. This【C9】________ brushing twice-a-day with fluoride (氯化物) toothpaste, cutting down on the frequency of sugary snacks and drinks and visiting a dentist【C10】________. [br] 【C5】
选项
答案
F
解析
此处需填入名词作宾语。这个实验是对比了两种情况的数据才得出第2段末的“受试者口腔内的硫化氢含量降低了”这一结论;要先有测量的数据才能进行对比,而测量的直接对象当然就是从这些受试者身上采集的口腔分泌物了。词库中只有samples“取样,样本”代入后符合上下文语境。
