Environmentally unsustainable diets are often characterized by being high in calories, processed foods, and red meats, characteristics related to away-from-home food (AFHF). The aim of this study is to evaluate if AFHF consumption is related to environmental sustainability. Data of 20,780 adults from 24 h recalls collected in the 2017-2018 Brazilian National Dietary Survey (NDS) were used to estimate carbon footprint coefficients. The mean carbon footprint was estimated among individuals who consumed AFHF and non-consumers. Linear regression models were used to evaluate differences between away-from-home eating and the carbon footprint of the diet, adjusting for age and income. A total of 41% of Brazilians consumed AFHF during the previous day. The mean carbon footprint from foods consumed away from home represented 18% of the total carbon footprint. AFHF was positively associated with increased total carbon footprint (β: 204.1; -value: 0.0145). In conclusion, the consumption of foods away from home in urban areas of Brazil was associated with atmospheric greenhouse gas emissions independently of age and income. Away-from-home food consumption should be considered to reinforce the influence of diet on individual and planet health.
环境不可持续的饮食通常具有高热量、加工食品和红肉的特点，这些特点与外出就餐（away-from-home food，AFHF）有关。本研究旨在评估 AFHF 的消费是否与环境可持续性有关。本研究使用了 2017-2018 年巴西国家饮食调查（NDS）中 24 小时回忆收集的 20780 名成年人的数据来估计碳足迹系数。在消费 AFHF 和非消费者中估计了个体的平均碳足迹。使用线性回归模型来评估外出就餐和饮食碳足迹之间的差异，同时调整年龄和收入。在过去的一天中，共有 41%的巴西人食用了 AFHF。从家中食用的食物的平均碳足迹占总碳足迹的 18%。AFHF 与总碳足迹的增加呈正相关（β：204.1；-值：0.0145）。总之，巴西城市地区外出就餐与大气温室气体排放有关，这与年龄和收入无关。应该考虑外出就餐，以加强饮食对个人和地球健康的影响。
