JAMA Intern Med:动植物蛋白摄入与全因及特定死亡风险

2019-08-27 MedSci MedSci原创

研究发现,较高的植物蛋白摄入与较低的总和心血管相关死亡率相关。用植物蛋白替代红肉或加工肉蛋白与较低的癌症及心血管死亡率相关

近日研究人员评估动植物蛋白质摄入量与全因和特定原因的死亡率之间的关系。

本次前瞻性队列研究包括70696名来自日本的志愿者,研究基线时年龄在45至74岁之间,没有癌症、脑血管病或缺血性心脏病病史。收集自1995年1月1日至1999年12月31日的数据,随访至2016年12月31日,期间共记录了12381人死亡。通过食物频率调查表收集膳食摄入量信息用于评估蛋白质摄入量。

研究发现,动物蛋白的摄入与总的或导致特定的死亡率无明显关联。相比之下,植物蛋白质摄入与较低的总死亡率相关,多变量调整后,相对于摄入植物蛋白最少的人群,次少、中等、次高以及最高人群的死亡风险比值比分别为0.89、0.88 、0.84以及0.87。就特定原因的死亡率而言,植物蛋白质摄入量与心血管疾病(CVD)相关死亡率的相关性最显著(0.84)。以植物蛋白代替3%能量红肉蛋白能量与较低的总死亡率(HR:0.66,)、癌症相关死亡率(0.61)和心血管疾病相关死亡率(0.58)有关,替代加工肉类蛋白质则与较低的总死亡率(0.54)和癌症相关死亡率(0.50)有关。

研究发现,较高的植物蛋白摄入与较低的总和心血管相关死亡率相关。用植物蛋白替代红肉或加工肉蛋白与较低的癌症及心血管死亡率相关。
