目的阐明健康和可持续的饮食；概述可用于选择纳入这种饮食的食物的主要健康和环境可持续性原则；描述一种评估H&S食品篮子的可用性和可负担性的方法。我们综合了来自学术、政府、工业和非政府来源的关于不同食物对环境影响的公开证据，并构建了一个假设的澳大利亚典型饮食的H&S等量。在此基础上，我们为一个有两个大人和两个孩子的家庭构建了一个每周的H&S食品篮子。结果H&S饮食基于三个总体原则：(i)任何超过个人能量需求的食物都是可避免的环境负担，其形式包括温室气体排放、自然资源的使用和对生物多样性的压力；（ii）减少随意选择的食物的消费，这些食物是能量密集的、经过高度加工和包装的，既减少了饮食不平衡的风险，也减少了环境资源的使用；（三）少吃动物性食物多吃植物性食物的饮食既有利于健康，又有利于生态。结论：我们关注健康与健康饮食的表述，不是为了促进“政策漂移”，关注个人的饮食选择，而是为了提供证据，扩展饮食指南建议，以便在澳大利亚和其他地方的食品和健康政策建议范围内整合环境考虑。
ObjectiveTo articulate a healthy and sustainable (H&S) diet; outline key health and environmental sustainability principles that can be applied in the selection of foods for inclusion in such a diet; and describe a methodology with which to assess the availability and affordability of a H&S food basket.DesignWe synthesized publically available evidence on the environmental impact of different foods from academic, government, industry and non-government sources and constructed a hypothetical H&S equivalent of the typical Australian diet. Based on this, we constructed a weekly H&S food basket for a household of two adults and two children.SettingAustralia.SubjectsAustralian populations.ResultsThe H&S diet is based on three overarching principles: (i) any food that is consumed above a person's energy requirement represents an avoidable environmental burden in the form of greenhouse gas emissions, use of natural resources and pressure on biodiversity; (ii) reducing the consumption of discretionary food choices, which are energy-dense and highly processed and packaged, reduces both the risk of dietary imbalances and the use of environmental resources; and (iii) a diet comprising less animal- and more plant-derived foods delivers both health and ecological benefits.ConclusionsWe have focused on the articulation of a H&S diet not to facilitate 'policy drift' to focus on individual dietary choice, but rather to provide evidence to extend dietary guideline recommendations so as to integrate environmental considerations within the scope of food and health policy advice in Australia and elsewhere.
