JACC:受欢迎的维生素和矿物质补充剂没有提供健康益处

2018-05-29 海北 MedSci原创

最近,来自多伦多大学的研究人员探究了补充维生素或微量元素对于心血管疾病的益处。

在过去的两个半世纪中,用维生素和矿物质治疗和预防微量营养素缺乏症是营养科学史上最引人注目的成就。最近,来自多伦多大学的研究人员探究了补充维生素或微量元素对于心血管疾病的益处。

研究人员从以前的荟萃分析和其他搜索中确定了个体随机对照试验,然后对心血管疾病结局和全因死亡率进行了荟萃分析。研究人员评估了2012年以前的出版物,包括美国预防性服务工作组综述。

研究人员的系统评价和荟萃分析显示,对于部分维生素或微量元素来说,预防性益处通常为中等或低质量证据(如叶酸预防总心血管疾病,叶酸和B族维生素治疗中风),或是无效(多种维生素,维生素CDβ-胡萝卜素,钙和硒),甚至会增加风险(抗氧化剂混合物和尼克酸[用他汀类药物]预防全因死亡率)。

因此,该研究显示,任何补充剂在所有饮食背景中的益处的确切证据(包括缺乏和充足)没有得到证明。因此,所看到的任何好处都必须与可能的风险相平衡。
