美国《公共科学图书馆·综合》杂志刊登的1项新研究发现,常嚼口香糖有助于去除口腔有害菌。仅仅嚼1片口香糖10min,就可去除1亿个口腔细菌(占唾液细菌的10%)。科学家发现,嚼口香糖30s,其去除口腔有害菌的作用最大,之后去菌作用会逐渐减弱。新研究还发现,只有无糖口香糖才能有效除菌。而含糖口香糖则起到相反的作用,因为口香糖中的糖分会成为口腔细菌的“美食”。科学家表示,嚼口 A new study published in the United States, “Public Library of Science · Integrated” magazine found that chewing gum can help to remove harmful oral bacteria. Just chewing a piece of chewing gum 10min, you can get rid of 100000000 oral bacteria (accounting for 10% of saliva bacteria). Scientists found that chewing gum 30s, the role of the removal of harmful bacteria in the mouth of the largest, then to the role of bacteria will gradually weakened. The new study also found that only sugar-free chewing gum to effective sterilization. Sugar-based chewing gum, on the other hand, has the opposite effect, because the sugar in the gum becomes the “gourmet” of the oral bacteria. Scientists said chewing mouth
