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

盡管你選擇的可能是健康的水果和堅果，可正是少食多餐的做法損害了你的牙齒健康。

‘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.’

研究人員表示：“牙齒每天能抵抗五次的酸性物質侵蝕。唾液要用一小時的時間才能中和掉由食物和飲料產生的酸性物質。這樣一來，如果你一整天都在小口啜飲一罐飲料，就等于那些酸性物質一直在攻擊你的牙齒。”

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.

如何補救：一日三餐外少吃零食。如果特別想吃，那么不要小口小口吃，一次吃完，這樣唾液可以盡快的中和掉口腔中的酸性物質。吃完后漱口或者嚼無糖口香糖促進唾液分泌，以助中和酸性。
