Vitamin and mineral supplements are a staple in many people's diets, but there is increasing evidence to suggest the most popular ones are essentially useless. 维生素和矿物质补充剂是许多人日常膳食中的固定组成部分，但越来越多的证据表明，最受欢迎的一些维生素补充剂其实都没什么用。 A new systematic review of data and trials published between January 2017 and October 2017 found that many popular multivitamins – as well as vitamin C, vitamin D, and calcium supplements – had no real advantage to people's health and that there was no evidence taking them reduced the risk of cardiovascular disease, heart attack, stroke, or early death. 一项对2017年1月至2017年10月间发布的数据和试验的系统回顾发现，维生素C、维生素D、钙质补充剂和许多受欢迎的复合维生素对人们的健康没有实质性的好处，而且没有证据表明服用这些维生素能够降低心血管疾病、心脏病发作、中风或早逝的风险。 |
