We assessed whether labeling restaurant menus with information on the nutrient content of menu items would cause customers to alter their ordering patterns.
Six full-service restaurants in Pierce County, Washington, added nutrition information to their menus, and they provided data on entrée sales for 30 days before and 30 days after the information was added. We assessed the prelabeling versus postlabeling difference in nutrient content of entrées sold, and we surveyed restaurant patrons about whether they noticed the nutrition information and used it in their ordering.
The average postlabeling entrée sold contained about 15 fewer calories, 1.5 fewer grams of fat, and 45 fewer milligrams of sodium than did the average entrée sold before labeling. Seventy-one percent of patrons reported noticing the nutrition information; 20.4% reported ordering an entrée lower in calories as a result, and 16.5% reported ordering an entrée lower in fat as a result.
The concentration of calorie reduction among 20.4% of patrons means that each calorie-reducing patron ordered about 75 fewer calories than they did before labeling. Thus, providing nutrition information on restaurant menus may encourage a subset of restaurant patrons to significantly alter their food choices.
我们评估了在餐厅菜单上标注食物营养成分信息是否会导致顾客改变点餐模式。
华盛顿州皮尔斯县的六家全方位服务餐厅在菜单上添加了营养信息,并提供了在添加信息前后 30 天的主菜销售数据。我们评估了销售主菜的营养成分在标签前后的差异,并调查了餐厅顾客是否注意到营养信息并在点餐时使用了这些信息。
与标签前相比,标签后的平均主菜销售含有约 15 卡路里、1.5 克脂肪和 45 毫克钠的摄入量减少。71%的顾客表示注意到了营养信息;20.4%的顾客表示因此点了热量较低的主菜,16.5%的顾客表示因此点了脂肪含量较低的主菜。
20.4%的顾客中,卡路里减少的集中程度意味着每个减少卡路里的顾客点的食物比标签前减少了约 75 卡路里。因此,在餐厅菜单上提供营养信息可能会鼓励一部分餐厅顾客显著改变他们的食物选择。
