It is well known that food has a considerable environmental impact. Less attention has been given to mapping and analysing the emergence of policy responses. This paper contributes to that process. It summarises emerging policy development on nutrition and sustainability, and explores difficulties in their integration. The paper describes some policy thinking at national, European and international levels of governance. It points to the existence of particular policy hotspots such as meat and dairy, sustainable diets and waste. Understanding the environmental impact of food systems challenges nutrition science to draw upon traditions of thinking which have recently been fragmented. These perspectives (life sciences, social and environmental) are all required if policy engagement and clarification is to occur. Sustainability issues offer opportunities for nutrition science and scientists to play a more central role in the policy analysis of future food systems. The task of revising current nutrition policy advice to become sustainable diet advice needs to begin at national and international levels.
众所周知，食物对环境有相当大的影响。然而，人们对食物政策应对措施的出现进行映射和分析的关注度较低。本文为这一进程做出了贡献。它总结了营养和可持续性方面新出现的政策发展，并探讨了它们融合的困难。本文描述了国家、欧洲和国际治理层面的一些政策思路。它指出了存在一些特定的政策热点，如肉类和奶制品、可持续饮食和浪费。了解食物系统的环境影响要求营养科学借鉴最近被割裂的传统思维模式。如果要进行政策参与和澄清，就需要这些视角（生命科学、社会和环境）。可持续性问题为营养科学和科学家提供了机会，使他们能够在未来食物系统的政策分析中发挥更核心的作用。将当前的营养政策建议修改为可持续饮食建议的任务需要从国家和国际层面开始。
