Healthy diets from sustainable food systems was the ostensible theme of the EAT–Lancet Commission. The four principal domains of sustainable diets, as defined by the Food and Agriculture Organization of the United Nations in 2010, were health, economics, society, and the environment. Sustainable diets were defined as those that were healthy, affordable, appealing, and environmentally friendly. Sustainable food systems are now defined as those that produce nutrient-rich foods that are affordable, socially and culturally acceptable, and sparing of both natural and human resources. Affordability was, and is, a key component of sustainable diets and of sustainable food systems.

分析EAT-Lancet饮食的负担能力。

可持续食品系统的健康饮食是EAT –柳叶刀委员会的表面主题。联合国粮食及农业组织在2010年定义的可持续饮食的四个主要领域是健康，经济，社会和环境。可持续饮食被定义为健康，负担得起，有吸引力且环保的饮食。现在，可持续粮食系统被定义为那些生产出营养丰富的食物的系统，这些食物负担得起，在社会和文化上可以接受，并节省自然资源和人力资源。负担能力过去是而且现在是可持续饮食和可持续粮食系统的关键组成部分。
