To evaluate red and processed meat intake, and the impact meat consumption has on diet quality and the environment.
A large cross-sectional health survey performed in São Paulo, Brazil.
Diet was assessed by two 24 h dietary recalls. Usual intakes were calculated using the Multiple Source Method. The World Cancer Research Fund recommendation of an average of 71.4 g/d was used as the cut-off point to estimate excessive red and processed meat consumption. To investigate the relationship between meat consumption and diet quality we used the Brazilian Healthy Eating Index Revised. The environmental impact was analysed according to estimates of CO2 equivalent emissions from meat consumption.
Brazilians (n 1677) aged 19 years and older were studied.
The mean red and processed meat intake was 138 g/d for men and 81 g/d for women. About 81% of men and 58% of women consumed more meat than recommended. Diet quality was inversely associated with excessive meat intake in men. In Brazil alone, greenhouse gas emissions from meat consumption, in 2003, were estimated at approximately 18,071,988 tonnes of CO2 equivalents, representing about 4% of the total CO2 emitted by agriculture.
The excessive meat intake, associated with poorer diet quality observed, support initiatives and policies advising to reduce red and processed meat intake to within the recommended amounts, as part of a healthy and environmentally sustainable diet.
评估红肉类和加工肉类的摄入量,以及肉类消费对饮食质量和环境的影响。
在巴西圣保罗进行的一项大型横断面健康调查。
通过两次 24 小时膳食回顾来评估饮食。使用多源法计算常规摄入量。将世界癌症研究基金会推荐的平均 71.4 克/天作为估计过多摄入红肉类和加工肉类的切点。为了研究肉类消费与饮食质量之间的关系,我们使用了经过修订的巴西健康饮食指数。根据肉类消费产生的二氧化碳当量排放量的估计,分析了环境影响。
研究了年龄在 19 岁及以上的巴西人(n=1677)。
男性和女性的平均红肉类和加工肉类摄入量分别为 138 克/天和 81 克/天。约 81%的男性和 58%的女性摄入的肉类超过了建议量。男性饮食质量与过量肉类摄入呈负相关。仅在巴西,2003 年肉类消费产生的温室气体排放量估计约为 18071988 吨二氧化碳当量,占农业总排放量的 4%左右。
摄入过多的肉类与观察到的较差的饮食质量有关,支持采取减少红肉类和加工肉类摄入至推荐量的倡议和政策,作为健康和环境可持续饮食的一部分。
