在全球范围内，约21-37%的温室气体（GHG）排放量可归因于食品系统。从1990年到2019年，全球范围内与饮食有关的非传染性疾病显著增加。为了实现碳排放目标，提高复原力，改善健康状况，需要提高农业的可持续性，改变饮食习惯。通过综合考虑这些挑战，并关注消费者与可持续生产之间的更紧密联系，我们可以从两者之间的积极互动中受益。这项研究使用2019年EAT Lancet委员会膳食指南，分析了从社区支持农业（CSA）计划成员和更广泛的英国人口中收集的访谈数据和食物日记。通过比较他们各自饮食的环境可持续性和营养质量，我们发现CSA成员的饮食比对照组更接近EAT Lancet的建议。我们发现，与对照组相比，CSA成员的肉类、乳制品、蔬菜、豆类和糖的每日摄入量存在显著差异，其饮食排放的二氧化碳平均减少28%。我们建议，农业和更广泛的社会和经济政策，增加CSA的可及性，为更多样化的人口可以支持实现健康，生物多样性和零排放的政策目标。
Globally, about 21–37% of total greenhouse gas (GHG) emissions are attributable to food systems. Dietary-related non-communicable diseases have increased significantly from 1990–2019 at a global scale. To achieve carbon emissions targets, increase resilience, and improve health there is a need to increase the sustainability of agricultural practises and change dietary habits. By considering these challenges together and focusing on a closer connection between consumers and sustainable production, we can benefit from a positive interaction between them. Using the 2019 EAT Lancet Commission dietary guidelines, this study analysed interview data and food diaries collected from members of Community Supported Agriculture (CSA) schemes and the wider UK population. By comparing the environmental sustainability and nutritional quality of their respective diets, we found that CSA members consumed diets closer to the EAT Lancet recommendations than controls. We identified significant differences in daily intakes of meat; dairy; vegetables; legumes; and sugar, and the diets of CSA members emitted on average 28% less CO2 compared to controls. We propose that agricultural and wider social and economic policies that increase the accessibility of CSAs for a more diverse demographic could support achieving health, biodiversity, and zero-emission policy targets.
