正如寿司爱好者所知,只需一点芥末就能起到很大作用。但这种辛辣的绿色辣根可能不仅仅是让你的金枪鱼卷更上一层楼。根据昨天在檀香山举行的环太平洋地区国际化学大会上发表的研究,芥末可能有助于预防蛀牙。日本小川香料株式会社材料研究开发实验室主任増田秀樹报告说,在试管研究中,芥末中发现的某些化合物——特别是异硫氰酸酯——抑制了导致龋齿的细菌变形链球菌的生长。増田说,这些异硫氰酸酯会干扰细胞对牙齿的糖依赖性粘附。(这种抗菌特性也可能解释了芥末作为生鱼片佐料的流行。)当然,基于芥末的牙齿护理产品是否会上市还有待观察。

Kate Wong is an award-winning science writer and senior editor at 大众科学 focused on evolution, ecology, anthropology, archaeology, paleontology and animal behavior. She is fascinated by human origins, which she has covered for more than 25 years. Recently she has become obsessed with birds. Her reporting has taken her to caves in France and Croatia that Neandertals once called home, to the shores of Kenya's Lake Turkana in search of the oldest stone tools in the world, to Madagascar on an expedition to unearth ancient mammals and dinosaurs, to the icy waters of Antarctica, where humpback whales feast on krill, and on a "Big Day" race around the state of Connecticut to find as many bird species as possible in 24 hours. Kate is co-author, with Donald Johanson, of Lucy's Legacy: The Quest for Human Origins. She holds a bachelor of science degree in biological anthropology and zoology from the University of Michigan.
