EAT-Lancet委员会利用所有可用的营养和环境证据构建了第一个能够维持健康和保护地球的全球基准饮食，但它没有评估饮食负担能力。我们使用食品价格和家庭收入数据来估计EAT-柳叶刀基准饮食的可负担性，作为指导干预措施改善世界各地diets.Methods的第一步，我们从2011年获得了744种食品在159个国家的零售价格，根据国际比较计划收集。我们使用这些数据来确定最实惠的食物，以满足EAT-Lancet的目标。我们将每天的总饮食成本与每个国家的人均家庭收入进行了比较，计算了最实惠的EAT-Lancet饮食超过总收入的人群比例，并测量了相对于满足基本营养需求的最低成本饮食的可负担性。结果最实惠的EAT-Lancet饮食的全球中位数为每天2.84美元（IQR 2.41-3-16），其中最大的份额是水果和蔬菜的成本（31.2%），其次是豆类和坚果（18.7%），肉类，鸡蛋和鱼类（15.2%）以及乳制品（13.2%）。这种饮食的成本只占高收入国家平均收入的一小部分，但世界上的穷人负担不起。我们估计，EAT-Lancet饮食的成本超过了至少15.8亿人的家庭人均收入。EAT-Lancet饮食也比营养充足的最低成本更昂贵，平均为1.60（IQR 1.41-1.78）。改善饮食在许多国家都是负担得起的，但对许多人来说，需要更高的收入、营养援助和更低的价格的某种结合。需要对更健康食品的成本进行数据和分析，以便为地方干预措施和系统性变革提供信息。版权所有（C）2019作者。爱思唯尔有限公司出版
Background The EAT-Lancet Commission drew on all available nutritional and environmental evidence to construct the first global benchmark diet capable of sustaining health and protecting the planet, but it did not assess dietary affordability. We used food price and household income data to estimate affordability of EAT-Lancet benchmark diets, as a first step to guiding interventions to improve diets around the world.Methods We obtained retail prices from 2011 for 744 foods in 159 countries, collected under the International Comparison Program. We used these data to identify the most affordable foods to meet EAT-Lancet targets. We compared total diet cost per day to each country's mean per capita household income, calculated the proportion of people for whom the most affordable EAT-Lancet diet exceeds total income, and also measured affordability relative to a least-cost diet that meets essential nutrient requirements.Findings The most affordable EAT-Lancet diets cost a global median of US$2.84 per day (IQR 2.41-3-16) in 2011, of which the largest share was the cost of fruits and vegetables (31.2%), followed by legumes and nuts (18.7%), meat, eggs, and fish (15.2%), and dairy (13.2%). This diet costs a small fraction of average incomes in high-income countries but is not affordable for the world's poor. We estimated that the cost of an EAT-Lancet diet exceeded household per capita income for at least 1.58 billion people. The EAT-Lancet diet is also more expensive than the minimum cost of nutrient adequacy, on average, by a mean factor of 1.60 (IQR 1.41-1.78).Interpretation Current diets differ greatly from EAT-Lancet targets. Improving diets is affordable in many countries but for many people would require some combination of higher income, nutritional assistance, and lower prices. Data and analysis for the cost of healthier foods are needed to inform both local interventions and systemic changes. Copyright (C) 2019 The Author(s). Published by Elsevier Ltd.
