COVID-19 大流行是一场“完美风暴”，正在考验食品系统的弹性和功能稳定性，因为它最终会影响家庭食品动态和消费者食品体验。这项基于跨国调查的研究实时研究了 COVID-19 大流行如何影响 1,732 个中国家庭和 1,547 个美国家庭在居家令期间以食品为中心的问题。两组人都报告说，食物的使用效率有所提高，家庭花更多的时间一起做饭和吃饭，并且更加谨慎地使用食物，减少浪费。食品购买模式从频繁去商店转变为在线订购的急剧增加。一小部分人（2% 的美国受访者和 11% 的中国受访者）报告称体重增加超过 4.5 公斤，具有临床意义。家庭粮食安全受到削弱，担心或经历粮食短缺的人数大幅增加。受访者的集体杂货购物经历表明，食品供应系统的功能稳定性保持稳定；除了中国人群普遍报告的价格明显较高之外，所有类型的食物都有所供应。这项研究提供了对粮食系统在面对大流行时的复原力的见解，并揭示了未来的粮食模式，以及有关人们在危机时期如何做出决策和粮食行为变化的进一步研究的长期问题。
The COVID-19 pandemic is a "perfect storm" that is testing the resilience and functional stability of the food system, as it ultimately affects household food dynamics and consumer food experiences. This cross-national survey-based study examined in real time how the COVID-19 pandemic impacted food-centric matters in 1,732 Chinese and 1,547 U.S. households during the stay-at-home directives. Both cohorts reported increased efficiency in the use of food, families spending more time cooking and eating together, and more prudent use of food with less waste. Food purchasing patterns shifted from frequent trips to the store to dramatic increases in online ordering. A small proportion (2% U.S. and 11% Chinese respondents) reported clinically significant weight gains of >4.5 kg. Household food security weakened, with large increases in people worrying about or experiencing food shortage. Collective grocery-shopping experiences by survey respondents indicated that the functional stability of food supply systems remained steady; all food types were somewhat available, except for noticeably higher prices widely reported by the Chinese cohort. This study offers insights into food system resilience when facing the pandemic and sheds light on future food patterns as well as long-term questions for additional research about how people make decisions and food behavioral changes at times of crisis.
