現金購物減肥 刷卡會買更多垃圾食品
Consumers who take cash to the shops and leave their debit cards at home are more likely to leave junk food on the shelves, U.S. scientists have discovered。
根據美國科學家的研究，用刷卡購物的人比用現金購物的更容易購買垃圾食品，也就是說，更容易發胖啦！
The study carried out by Cornell University and the University at Buffalo analysed the shopping behaviour of 1,000 households. They found that supermarket trolleys had a larger proportion of junk food items when the shopper was using credit or debit cards rather than cash。
根據康奈爾大學和水牛城大學對美國1000戶普通家庭的調查，研究人員發現，當人們刷卡付錢的時候，購物車裏垃圾食品的比率大大高於用現金購物的人。
'Two factors contribute to this intriguing effect,' the authors explained. 'First, there is a correlation between unhealthiness and impulsiveness of food items: unhealthy food items tend to elicit impulsive responses。
研究人員說：“造成這個有趣現象的原因很多，首先不健康是和對食物的衝動緊密相連的，不健康的食物種類可以引發衝動的反應；第二，使用現金付款比用信用卡付款給人心理上造成的痛苦更多，因此用現金消費引發的痛苦會抑制大家購買垃圾食品的衝動性。”
'Second, cash payments are psychologically more painful than card payments, and this pain of payment can curb the impulsive responses to buy unhealthy food items.'
美國科學家甚至認爲，造成西方人普遍肥胖的原因之一就是他們都刷卡付錢，這個方式造成了人民的肥胖——根據2008年英國的數據統計，1/4的英國人都體重超標——如果改變一下消費方式呢？
They even suggested that there may even be a connection between rising obesity levels in western countries and changing modes of payment。
大家可以觀察一下，是不是瘦人一般用現金比較多？而胖子一般都刷卡？
