Abstract：
The future of plant-based diets is a complex public health issue inextricably linked to planetary health. Shifting the world\'s population to consume nutrient-rich, plant-based diets is among the most impactful strategies to transition to sustainable food systems to feed 10 billion people by 2050. This review summarizes how international expert bodies define sustainable diets and food systems and describes types of sustainable dietary patterns. It also explores how the type and proportion of plant- versus animal-source foods and alternative proteins relate to sustainable diets to reduce diet-related morbidity and mortality. Thereafter, we synthesize evidence for current challenges and actions needed to achieve plant-based sustainable dietary patterns using a conceptual framework with principles to promote human health, ecological health, social equity, and economic prosperity. We recommend strategies for governments, businesses, and civil society to encourage marketplace choices that lead to plant-rich sustainable diets within healthy, equitable, and resilient agroecological food systems.
摘要：
植物性饮食的未来是一个复杂的公共卫生问题，与行星健康密不可分。将世界人口转移到营养丰富的国家，植物性饮食是到2050年向可持续粮食系统过渡以养活100亿人口的最有影响力的战略之一。这篇综述总结了国际专家机构如何定义可持续饮食和食物系统，并描述了可持续饮食模式的类型。它还探讨了植物与动物源食品和替代蛋白质的类型和比例如何与可持续饮食相关，以减少与饮食相关的发病率和死亡率。此后,我们使用具有促进人类健康原则的概念框架，综合了实现基于植物的可持续饮食模式所需的当前挑战和行动的证据。生态健康,社会公平，和经济繁荣。我们为政府推荐策略，企业,和民间社会鼓励市场选择，在健康的情况下实现富含植物的可持续饮食，公平,和有弹性的农业生态食物系统。
