This review explores opportunities to shift food systems towards healthy diets and secure food yields while remaining within planetary resource boundaries. Drawing on improved global data on the environmental impacts of different foods, we adopt a systems perspective to examine the interconnected nexus of health, diets and the global environment, with particular attention to the role of future urban food systems. As the global population becomes increasingly urbanised, cities have the potential to reshape food systems and urban infrastructure. Our analysis suggests that the Earth could feed some 10 billion people by the end of the century on less than half of today’s agricultural land if diets shift towards more plant-based and soilless foods, food waste is substantially reduced, and nutrients from urban waste streams are recycled as complementary fertilisers. Such changes could halve food-related air emissions, help restore biodiversity and contain the risk of crossing several planetary boundaries. They could also halt further expansion of cropland and pasture. From a health perspective, a shift towards predominantly plant-based diets, combined with lower intakes of calories, sugar, salt, fat, red meat and ultra-processed foods, could reduce obesity and non-communicable diseases, potentially extending life expectancy by up to a decade and preventing an estimated 15 million premature deaths annually. Importantly, many of these interventions could generate benefits within months or years, making dietary change and nutrient recycling potentially much faster levers for transformation than changes to long-lived infrastructure such as cars and roads.","当前粮食生产和消费模式被广泛认为不可持续。本综述探讨了在保持在地球资源边界内的同时，将粮食系统转向健康膳食和保障粮食产量的机遇。基于对不同食物环境影响改进后的全球数据，我们采用系统视角审视健康、膳食与全球环境之间相互关联的纽带，尤其关注未来城市粮食系统的作用。随着全球人口日益城市化，城市有潜力重塑粮食系统和城市基础设施。我们的分析表明，如果膳食转向更多以植物为基础和无土栽培的食物，食物浪费大幅减少，且城市废物流中的养分作为补充肥料被回收利用，那么到本世纪末，地球仅需不到当今农业用地的一半就能养活约100亿人口。此类变化可使与食物相关的空气排放减半，有助于恢复生物多样性，并遏制跨越多个地球边界的风险。它们还可以阻止农田和牧场的进一步扩张。从健康角度看，转向以植物为主的膳食，结合降低热量、糖、盐、脂肪、红肉和超加工食品的摄入量，可以减少肥胖和非传染性疾病， potentially延长预期寿命长达十年，并每年防止约1500万例过早死亡。重要的是，许多此类干预措施可在数月或数年内产生效益，使得膳食改变和养分回收成为比改变汽车和道路等长寿命基础设施更快的转型杠杆。",null,"Frontiers in Sustainable Food Systems","2026-09-17T00:00:00Z","论文",10,false,87,{"impact":17,"substance":18,"depth":19,"authority":20,"freshness":13,"relevant":21,"comment":22},24,22,18,13,1,"基于全球数据的系统综述，提出植物基饮食、城市废弃物养分回收与减少浪费可在本世纪末以不足一半农地养活百亿人口，结论新颖且政策启示强，值得进入每日精选。",[24],{"name":10,"url":6},[26,27,28,29,30,31],"可持续农业","城市农业","食物浪费","食物系统转型","植物基饮食","养分循环",0,"10.3389\u002Ffsufs.2026.1881497",{"doi":33,"openalex_id":35,"authors":36,"venue":10,"cited_by_count":32,"oa_url":6,"card":39,"direction":43,"ingested_from":45},"W7213465358",[37],{"name":38,"orcid":9},"Jan-Olof Drangert",{"tldr":40,"method":41,"finding":42,"direction":43,"opportunity":44},"综述提出通过转向植物基饮食、减少浪费和回收城市养分，可在半量农地上养活百亿人并改善健康。","基于全球食物环境影响数据，采用系统视角分析健康、饮食与环境的关联。","植物基饮食加城市养分回收可减半食物排放、恢复生物多样性并每年避免1500万过早死亡。","农业绿色发展与碳","可研究城市有机废弃物养分回收技术及植物基\u002F无土食物本地化生产系统的落地路径。","openalex","2026-09-17T23:30:07.297934Z"]
