We surveyed 7318 customers from 275 randomly selected restaurants of 11 fast food chains. Participants purchased a mean of 827 calories, with 34% purchasing 1000 calories or more. Unlike other chains, Subway posted calorie information at point of purchase and its patrons more often reported seeing calorie information than patrons of other chains (32% vs 4%; P<.001); Subway patrons who saw calorie information purchased 52 fewer calories than did other Subway patrons (P<.01). Fast-food chains should display calorie information prominently at point of purchase, where it can be seen and used to inform purchases.
我们对来自11家快餐连锁店中275家随机抽取餐厅的7318名顾客进行了调查。参与者平均购买了827卡路里的食物，其中34%的人购买了1000卡路里及以上。与其他连锁店不同，赛百味在购买点张贴了卡路里信息，其顾客比其他连锁店的顾客更常报告看到卡路里信息（32%对4%；P<0.001）；看到卡路里信息的赛百味顾客比其他赛百味顾客少购买52卡路里（P<0.01）。快餐连锁店应在购买点显著展示卡路里信息，以便顾客能够看到并用于指导购买决策。
