常喝葡萄酒能保护心脏吗?

27 Oct 2022

Description

流言:有流言成,葡萄酒中含有能保护心脏的白藜芦醇,常喝有助于健康真相:白藜芦醇对心脏有一定的保护作用,但相关研究大多都局限于动物实验,白藜芦醇的最佳剂量尚未在人体研究中得到证实。某些研究中提到根据白藜芦醇对动物的有效剂量推算到人类,对于人的有效剂量为1克/天。但有数据显示:红葡萄酒的白藜芦醇浓度为0.361-1.972毫克/升,要想通过喝红酒满足每天摄入1克白藜芦醇,那需要喝掉几百瓶红葡萄酒。考虑到酒精对人体的不良影响,喝酒补白藜芦醇可能弊大于利。再说,白藜芦醇不只存在于葡萄酒中,葡萄、苹果、蓝莓、李子、花生中也都有,不见得非要喝酒。
