Sugar-Free Gum 无糖口香糖

  You won't hear many positive health claims surrounding artificial sweeteners, but when it comes to dental health, there's one exception: Xylitol. The sugar replacement, which is found in many sugar-free gums and mints, is helpful because it prevents harmful bacteria in plaque from metabolizing sugar, thus generating harmful acids that degrade tooth enamel. In other words, it's the anti-sugar -- doing exactly the opposite of what sucrose can do, which is feed the bacteria that leads to tooth decay and gum disease。

    关于人工甜味剂对健康有益的正面报道不是很多,但是对牙齿健康而言,就有一个例外:木糖醇。在很多无糖口香糖和薄荷糖里面都有这种糖替代 品。它对牙齿有益,能够阻止牙菌斑里的有害细菌进行代谢,这种细菌能产生损害牙釉质的有害牙斑酸。 换句话说,它是抗糖,作用正好和蔗糖相反,蔗糖能促进细菌的繁殖从而导致蛀牙和牙周病。
