虽然Jolly Ranchers等硬糖不会像软糖那么粘牙,但也存在弊端。比如,巧克力味的糖果更容易咀嚼,漱口的时候也更容易去除残留,但硬糖溶解缓慢,给予细菌更多的时间产生有害酸。更糟糕的是,很多硬糖都是柠檬酸味的。
Pickles
腌黄瓜
Acid (typically provided by vinegar) is essential to the pickling process. It's what gives pickles their sour, salty taste-and it's also what makes them a potential hazard to tooth enamel. In one 2004 study that looked at the eating habits of English teenagers, pickles were the solid food most closely linked with tooth wear. Eating them more than once a day increased the odds of wear by about 85%.
腌黄瓜可不能缺了酸(通常以醋的形式)。这样做成的腌黄瓜才会酸酸咸咸的--但也对牙釉质带来了潜在危害。2017年,一项有关英国青少年饮食习惯的研究发现:腌黄瓜是与牙齿磨损最相关的固态食物。每天吃一次以上会使牙齿磨损的几率增加约85%。
Most of us don't eat pickles that often, however, and snacking on them every now and then isn't likely to noticeably affect your dental health, Messina says.
但是,大多数人吃腌黄瓜的次数并没有那么频繁,时不时的吃一两次并不会为牙齿健康带来显著影响,墨西拿说道。
Soda
苏打水
It's no secret that drinking too many sugary sodas can breed cavities. What's less well-known is that the acids found in carbonated soft drinks appear to harm teeth even more than the sugar. The upshot? Even sugar-free diet sodas like Diet Coke and Diet Pepsi-which both contain citric and phosphoric acid-can erode enamel.
