研究發(fā)現(xiàn)：維生素片大多沒啥用 吃錯還會致病
不要再浪費(fèi)錢買維生素片了！研究發(fā)現(xiàn)，大多數(shù)維生素片和礦物質(zhì)補(bǔ)充劑都沒什么用。維生素C也不像傳說中的能讓感冒好得快?？茖W(xué)家還指出，不要以為復(fù)合維生素就可以替代平衡膳食，維生素也不能亂吃，吃錯了可能致病甚至提高死亡風(fēng)險。
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.
維生素和礦物質(zhì)補(bǔ)充劑是許多人日常膳食中的固定組成部分，但越來越多的證據(jù)表明，最受歡迎的一些維生素補(bǔ)充劑其實(shí)都沒什么用。
A new systematic review of data and trials published between January 2024 and October 2024 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.
一項(xiàng)對2024年1月至2024年10月間發(fā)布的數(shù)據(jù)和試驗(yàn)的系統(tǒng)回顧發(fā)現(xiàn)，維生素C、維生素D、鈣質(zhì)補(bǔ)充劑和許多受歡迎的復(fù)合維生素對人們的健康沒有實(shí)質(zhì)性的好處，而且沒有證據(jù)表明服用這些維生素能夠降低心血管疾病、心臟病發(fā)作、中風(fēng)或早逝的風(fēng)險。
The study, published in the Journal of the American College of Cardiology, was led by researchers at St. Michael's Hospital and the University of Toronto.
這項(xiàng)發(fā)表在《美國心臟病學(xué)會期刊》上的研究是由圣米高醫(yī)院和多倫多大學(xué)的研究人員帶頭開展的。
"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.
研究報告的主要作者戴維·詹金斯博士稱：“我們驚訝地發(fā)現(xiàn)，人們最常服用的補(bǔ)充劑居然收效甚微。”
"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."
“我們的回顧發(fā)現(xiàn)，如果你想服用復(fù)合維生素、維生素D、鈣片或維生素C，對你的身體是無害的，但也沒有明顯的益處?！?/p>
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.
不過，研究也發(fā)現(xiàn)了幾種對人體明顯有益的補(bǔ)充劑。葉酸和含有葉酸的復(fù)合維生素B或許能降低患心血管疾病和中風(fēng)的風(fēng)險。
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，煙酸（維生素B3）和抗氧化劑會導(dǎo)致死亡風(fēng)險升高，不過只是略微升高。
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.
研究人員稱，這可能和煙酸對血糖水平的負(fù)面影響有關(guān)。研究指出，大量服用抗氧化劑會對人體有害。
Alternatively, it could have something to do with people sometimes thinking that taking vitamins can be a substitute for a healthy, balanced diet.
另一方面，服用維生素?zé)o益也和人們的觀念誤區(qū)有關(guān)，有些人認(rèn)為服用維生素可以替代健康平衡的膳食。
"These findings suggest that people should be conscious of the supplements they're taking and ensure they're applicable to the specific vitamin or mineral deficiencies they have been advised of by their healthcare provider," Jenkins said.
詹金斯說：“研究結(jié)果表明，人們應(yīng)該了解自己服用的補(bǔ)充劑，聽從醫(yī)囑，確保這些補(bǔ)充劑能補(bǔ)充自身所缺乏的某種維生素或礦物質(zhì)?！?/p>
The vitamins the team reviewed were A, B1, B2, B3 (niacin), B6, B9 (folic acid), C, D, and E, as well as carotene, calcium, iron, zinc, magnesium, and selenium.
研究團(tuán)隊(duì)的研究對象包括維生素A、維生素B1、維生素B2、維生素B3（煙酸）、維生素B6、維生素B9（葉酸）、維生素C、維生素D和維生素E，還有胡蘿卜素、鈣、鐵、鋅、鎂和硒。
Research has found that some vitamins are more useful than others. For example, zinc has been linked to shortening the effects of a cold – something vitamin C doesn't do, despite what people think.
研究發(fā)現(xiàn)，一些維生素比其他維生素更有用。比如，鋅能縮短感冒周期，而維生素C卻不能，盡管人們一直以為維生素C能讓感冒好得快。
Vitamin D can also be difficult to get from food, so if you're deficient, supplements may also be effective.
維生素D難以從食物中獲得，所以如果你缺乏維生素D，那么服用補(bǔ)充劑會比較有效。
"In the absence of significant positive data – apart from folic acid's potential reduction in the risk of stroke and heart disease – it's most beneficial to rely on a healthy diet to get your fill of vitamins and minerals," Jenkins said.
詹金斯說：“除了葉酸可能降低中風(fēng)和心臟病風(fēng)險外，沒有足夠數(shù)據(jù)表明服用補(bǔ)充劑對人體有益，因此最好還是從健康膳食中獲取你所需要的維生素和礦物質(zhì)?！?/p>
"So far, no research on supplements has shown us anything better than healthy servings of less processed plant foods, including vegetables, fruits, and nuts."
“迄今為止，沒有任何一項(xiàng)關(guān)于補(bǔ)充劑的研究顯示有任何藥物比攝入健康的輕度加工植物食品（包括蔬菜、水果和堅(jiān)果）更好。”
