　　Even if you’re snacking on healthy fruit, seeds and nuts, it’s eating little and often that can do your teeth harm.

　　尽管你选择的可能是健康的水果和坚果，可正是少食多餐的做法损害了你的牙齿健康。

　　‘A tooth can withstand five acid attacks a day,’ says one researcher. ‘Saliva takes about an hour to neutralise the acid created by a food or drink. So if you have a can of fizzy drink and sip it all day long, then the acid in your mouth will be under constant attack.’

　　研究人员表示：“牙齿每天能抵抗五次的酸性物质侵蚀。唾液要用一小时的时间才能中和掉由食物和饮料产生的酸性物质。这样一来，如果你一整天都在小口啜饮一罐饮料，就等于那些酸性物质一直在攻击你的牙齿。”

　　REDUCE THE RISK: Stick to three meals a day and avoid snacking. If you must snack, eat it all at once, rather than picking at it, so that the saliva can quickly neutralise the acid generated in the mouth. After food, rinse your mouth out with water or chew sugar-free gum to encourage saliva, which neutralises the acid.

　　如何补救：一日三餐外少吃零食。如果特别想吃，那么不要小口小口吃，一次吃完，这样唾液可以尽快的中和掉口腔中的酸性物质。吃完后漱口或者嚼无糖口香糖促进唾液分泌，以助中和酸性。
