无糖饮料或糖果通常被认为对人们牙齿的损坏要比较少,但最近澳大利亚进行的一项研究则表明有糖饮料和无糖饮料对人们牙齿造成的损害没有明显的差异。据合众社报道,无糖食品和饮料由于含有高酸成分,因而对人们牙齿造成的损害和有糖食品很是相似。牙齿损坏主要是由于酸溶解了牙齿的硬组织,而且损毁通常是从牙齿的釉质层开始进行。人们喝了含糖饮料后口腔中的细菌就会产生酸,因而通常认为吃或喝含糖较少的食品会减少酸的产生。澳大利亚墨尔本大学进行的一项最新研究,则对各种含糖和不含糖的饮料进行了对比,最终发现含糖或不含糖的各种 Sugar-free drinks or candy are generally thought to be less damaging to people’s teeth, but a recent study in Australia showed that there was no significant difference in the damage done to people’s teeth between sugar-sweetened and sugar-free drinks. According to the UNICEF report, sugar-free foods and beverages contain very high levels of acid and are therefore very similar to people’s teeth damage and sugary foods. Teeth damage is mainly due to the hard tissue where the acid dissolves the teeth, and the damage usually starts with the enamel layer of the teeth. When people drink sugary drinks, the bacteria in their mouth produce acid, so eating or drinking less sugary foods is usually thought to reduce acid production. A recent study conducted by the University of Melbourne in Australia compared various types of sugary and non-sugary beverages, eventually finding sugary or non-sugary
