Date labels, food waste and supply chain implications
通过调查消费者面对不同日期标签时丢弃15种食品的意愿，发现某些标签能减少浪费但效果因食品种类而异，且从'Best by'改为'Best if Used by'会增加家庭能量和脂肪等营养素的购买量。
Abstract We developed a survey to collect information on consumers’ intentions to discard 15 food products when exposed to different date labels. Results show that the use of certain date labels has the capacity to reduce food waste, but the reductions would happen differentially across food groups. When we examine the nutritional implications, we find that a shift from the ‘Best by’ date label to the ‘Best if Used by’ date label would increase total household purchases of energy and lead to a disproportional increase in purchases of fats, cholesterol and protein.
