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(氟化物)toothpaste, cutting down on the frequency of sugary snacks and drinks and visiting a dentist【C10】______. [br] 【C1】
选项
答案
E
解析
空格处需填入动词作从句谓语,因主句为过去时,所以需要填入动词过去式。第2段最后一句提到80%受试者喝了酸奶后口腔内的硫化氢降低了(decreased),据此可知喝酸奶会降低硫化氢的含量,词库中动词reduced“降低”与decreased意思相近,符合语义。
