逛超市的時候，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。

一項研究發(fā)現(xiàn)，在購物前吃一個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.

這個研究小組開展了三項研究來證明健康的零食是否能引發(fā)消費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.

在第一個研究里，120名購物者在到達超市的時候被隨機給到一小塊蘋果，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。
