Daily multivitamin supplements don't help you live longer, study shows
研究表明，每日补充多种维生素无助于延长寿命
Multivitamin supplements have become a routine addition to many Americans' diets, with as many as 1 in 3 U.S. adults consuming them regularly, but are these daily doses improving overall health and longevity?
复合维生素补充剂已成为许多美国人饮食中的日常补充品，据统计，多达三分之一的美国成年人定期服用它们，但这些日常剂量真的能提高整体健康和延长寿命吗？
A study from the National Institutes of Health (NIH) published Wednesday found that multivitamins won't help extend your life, with researchers reporting, "multivitamin use to improve longevity is not supported."
周三发表的一项来自美国国家卫生研究院的研究发现，复合维生素并不能帮助延长寿命，研究人员报告称，“服用复合维生素并不能延长寿命”。
The study analyzed data from nearly 400,000 adults over 20 years. Participants had a median age of 61.5 years old and were generally healthy, with no history of chronic diseases, according to the study published in JAMA Network Open.
该研究分析了近40万名成年人在20多年内的数据。据发表在 JAMA Network Open 上的研究，参与者平均年龄为61.5岁，健康状况良好，没有慢性病史。
The study found no evidence that daily multivitamin consumption reduced the risk of death from conditions such as heart disease or cancer.
研究发现，没有证据表明每天服用复合维生素能降低心脏病或癌症等疾病导致的死亡风险。
Rather than living longer, otherwise healthy people who took daily multivitamins were slightly more likely (4%) than non-users to die in the study period, according to researchers.
根据研究人员的说法，相较于未服用者，服用日常复合维生素的健康人在研究期间死亡的可能性略高（4%）。
Researchers reported nearly 165,000 deaths occurring during the follow-up period of the study, out of the initial group of 390,000 participants. The study, however, did not analyze data from people with pre-existing vitamin deficiencies.
研究人员报告称，在研究的随访期间，最初的39万名参与者中有近16.5万人死亡。然而，该研究并未分析患有维生素缺乏症的人的数据。
"What this study shows is that, generally, multivitamins aren't going to help you live longer," says Dr. Jade A Cobern, MD, MPH, board-certified physician in pediatrics and general preventive medicine.
儿科和一般预防医学委员会认证的医生 Jade A Cobern 博士表示：“这项研究表明，一般来说，复合维生素并不能帮助你活得更长。”
"Even though the cost of many multivitamins isn't high, this is still an expense that many people can be spared from," Cobern said.
Cobern 补充说：“尽管许多复合维生素的成本不高，但这仍然是一项可以避免的开支。”
苏格拉底有一句名言：我知我无知。说的是，当你认识到的东西越多就越发现自己无知。苏格拉底认为，人对于客观世界的认识是有限的，且不可能完全认识客观世界，并且不应对客观世界刨根究底。神对于世界的规划自有安排，若人一意孤行地探索世界和自然的奥秘，则最终将亵渎甚至触怒神明。正因为人对神所构建的世界不可能实现完全认知，因此那些宣称自己能够认识和改造世界的人，本身便是无知的代言。尽管苏格拉底的关于“ 我知我无知”的观念的解读，在现在看来有失客观科学。但至少苏格拉底告诫人们，人的认知是有限的，现有的知识甚至可能存在错误和疏漏。因此，无论任何时代，我们都必须对自己的无知加以认识并通过不懈的开拓，去更新甚至颠覆固有的知识结构。我们在求学之路上也要报以我知我不知的心态，才能走得更远、终有所成。最后，祝愿每一位考研学子都能顺利上岸！
