Many of us find it difficult to avoid the chocolate and crisps aisles in the supermarket, not to mention the desserts fridge.

逛超市的時(shí)候，很多人都會發(fā)現(xiàn)自己很難不去逛逛巧克力及膨化食品商品通道，更不用說甜品柜了。

Now, researchers have discovered a simple way to help shoppers control the urges to buy unhealthy foods.

現(xiàn)在，研究人員發(fā)現(xiàn)了一個(gè)簡單的方法，幫助購物者去控制自己想買不健康食物的沖動。

Eating an apple before going shopping causes a person to buy 25 percent more fruit and vegetables, a study found.

一項(xiàng)研究發(fā)現(xiàn)，在購物前吃一個(gè)蘋果能讓人買比原來多25%數(shù)量的蔬菜和水果。

The team carried out three studies to find out if healthy snacks cause shoppers to make better food choices in the shop.

這個(gè)研究小組開展了三項(xiàng)研究來證明健康的零食是否能引發(fā)消費(fèi)者更健康的食品購物選擇。

In the first study, 120 shoppers were randomly given either a bit of apple, a piece of cookie or nothing at all when they arrived at the supermarket.

在第一個(gè)研究里，120名購物者在到達(dá)超市的時(shí)候被隨機(jī)給到一小塊蘋果，一片餅干或是什么都沒給。

The researchers tracked their purchases and found those who were given the apple bought 28 per cent more fruits and vegetables than those given the cookie.

研究者后續(xù)追蹤了他們的購物單，發(fā)現(xiàn)那些之前給了蘋果片的人要比給了餅干的人多買了28%的水果和蔬菜。

And they bought 25 percent more fruits and vegetables than those given no snack at all at the start of their shopping.

他們比購物前那些什么都沒給到的人也多買了25%的水果和蔬菜。

Dr Aner Tal, of Cornell University, who carried out the research with his colleague Dr Brian Wansink, said: 'What this teaches us is that having a small healthy snack before shopping can put us in a healthier mindset and steer us towards making better food choices.

開展這項(xiàng)研究的康奈爾大學(xué)博士Aner Tal和他的同事Brian Wansink說：“這個(gè)實(shí)驗(yàn)告訴我們在購物前吃上一些健康的食物能讓我們心態(tài)更健康，并傾向于作出更好的食品購買選擇。
