【写在最后】

2018年，《柳叶刀》一份研究涉及了全球2800个饮酒人，研究结果表明，无论饮酒多少，都会对人体造成伤害，饮酒没有任何的“安全值”！最安全的饮酒量为0。

刊登在《英国医学杂志（BMJ）》杂志的一份长达30年的研究，对550名饮酒者进行跟踪调查，并对他们的大脑进行了核磁共振扫描。

研究结果显示：

每周摄入240g酒精（约1斤白酒）的人，海马体萎缩的风险最高，达到了不饮酒者的5.8倍。而适度饮酒，每周摄入56~168g酒精的人，右侧海马体萎缩的风险是不饮酒的3.4倍。即便是轻度饮酒，每周摄入8~56g酒精的人，海马体依然存在萎缩风险。

普通人一般认为，喝酒伤身也就喝酒的那一两天，随着酒精代谢掉，对人体的伤害就会消失。然而美国的一项研究显示，酒精的伤害远远不止一两天，至少长达6周的时间，神经信号之间的传递都会受到限制，大脑神经元之间的沟通，发生了长久的改变。
