【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。
