Food systems are at the center of a brewing storm consisting of a rapidly changing climate, rising hunger and malnutrition, and significant social inequities. At the same time, there are vast opportunities to ensure that food systems produce healthy and safe food in equitable ways that promote environmental sustainability, especially if the world can come together at the UN Food Systems Summit in late 2021 and make strong and binding commitments toward food system transformation. The NIH-funded Nutrition Obesity Research Center at Harvard and the Harvard Medical School Division of Nutrition held their 22nd annual Harvard Nutrition Obesity Symposium entitled "Global Food Systems and Sustainable Nutrition in the 21st Century" in June 2021. This article presents a synthesis of this symposium and highlights the importance of food systems to addressing the burden of malnutrition and noncommunicable diseases, climate change, and the related economic and social inequities. Transformation of food systems is possible, and the nutrition and health communities have a significant role to play in this transformative process.
食物系统处于一场酝酿中的风暴的中心，这场风暴由快速变化的气候、不断上升的饥饿和营养不良以及严重的社会不平等构成。与此同时，也有巨大的机会确保食物系统以公平的方式生产健康和安全的食物，促进环境可持续性，特别是如果世界能够在 2021 年底的联合国粮食系统峰会上团结起来，并为粮食系统转型做出有力和具有约束力的承诺。由美国国立卫生研究院资助的哈佛营养肥胖研究中心和哈佛医学院营养系于 2021 年 6 月举办了第 22 届年度哈佛营养肥胖研讨会，题为“21 世纪的全球食物系统与可持续营养”。本文综合了这次研讨会的内容，并强调了食物系统在应对营养不良和非传染性疾病负担、气候变化以及相关的经济和社会不平等方面的重要性。食物系统的转型是可能的，营养和健康界在这一转型过程中可以发挥重要作用。
