研究发现：维生素片大多没啥用吃错还会致病

这项发表在《美国心脏病学会期刊》上的研究是由圣米高医院和多伦多大学的研究人员带头开展的。

"We were surprised to find so few positive effects of the most common supplements that people consume," said Dr. David Jenkins, the lead author of the study.

研究报告的主要作者戴维·詹金斯博士称：“我们惊讶地发现，人们最常服用的补充剂居然收效甚微。”

"Our review found that if you want to use multivitamins, vitamin D, calcium or vitamin C, it does no harm – but there is no apparent advantage either."

“我们的回顾发现，如果你想服用复合维生素、维生素D、钙片或维生素C，对你的身体是无害的，但也没有明显的益处。”

There were, however, a few apparently advantageous supplements. Folic acid and B vitamins with folic acid may reduce the risk of cardiovascular disease and stroke, the study found.

不过，研究也发现了几种对人体明显有益的补充剂。叶酸和含有叶酸的复合维生素B或许能降低患心血管疾病和中风的风险。

Niacin (a form of vitamin B3) and antioxidants, meanwhile, were associated with a higher risk of death by any cause, albeit a very small increase.

此外，烟酸（维生素B3）和抗氧化剂会导致死亡风险升高，不过只是略微升高。

The researchers say these higher risks could be related to niacin's adverse effects on blood-sugar levels, or that when taken in high doses, antioxidants can be harmful.
