咖啡健康吗?
Yes, go ahead and grab that cup of joe, or two, or more. Doing so may improve your health and help youlive longer, suggests new research.
是的，去拿那杯咖啡，一两杯，或者更多，一项新的研究表明，这样做可以改善你的健康，帮助你活得更长。
In an observational study involving close to 20,000 individuals, people who consumed at least four cups of coffee daily had a 64% lower risk of early deathcompared to those never or rarely consumed coffee.
在一项涉及近2万人的观察性研究中，每天至少喝四杯咖啡的人早逝的风险比从不或很少喝咖啡的人低64%。
A new study has shown coffee can reduce your risk of early death.
一项新的研究表明，咖啡可以降低早逝的风险。
The reduction in risk was more significant once people reached the age of 45, suggesting that it may be even more beneficial to consume coffee as we get older.
一旦人们到了45岁，患病风险的降低就会更加显著，这表明随着年龄的增长，喝咖啡可能会更加有益。
These findings echo the recent results of another large observational study, which found that coffee drinkers appear to live longer, regardless of whether they consume regular or decaf.
这些发现与最近另一项大型观察性研究的结果相呼应。该研究发现，喝咖啡的人似乎更长寿，不管他们是经常喝咖啡还是不喝咖啡。
Coffee has also been shown to reduce the risk of many diseases, including type 2 diabetes, liver disease, colorectal cancer, Alzheimer's and skin cancer, too.
咖啡还被证明可以降低许多疾病的风险，包括2型糖尿病、肝病、结肠癌、阿尔茨海默氏症和皮肤癌。
"Coffee is loaded with antioxidants," said Joe DeRupo, a spokesman for the National Coffee Association. "Many are naturally occurring antioxidants found in the coffee bean, while others are created during the roasting process. It's these compounds that science links with positive effects in reducing the risk of several diseases."
“咖啡富含抗氧化剂，”国家咖啡协会发言人乔·德鲁普说。“其中许多是咖啡豆中天然存在的抗氧化剂，而另一些则是在烘焙过程中产生的。科学证明，正是这些化合物对降低几种疾病的风险有积极作用。”
Some of the compounds commonly found in coffee "have been related to better insulin sensitivity, liver function and reduced chronic inflammation," said V. Wendy Setiawan, an associate professor of preventive medicine at the Keck School of Medicine of USC, and the lead author of one of the recent studies on coffee consumption and longevity.
南加州大学凯克医学院(Keck School Of Medicine Of USC)预防医学副教授V·温迪·塞蒂亚万(V.Wendy Setiawan)说，咖啡中常见的一些化合物“与更好的胰岛素敏感性、肝功能和减少慢性炎症有关”，也是最近一项关于咖啡消费和寿命的研究的主要作者之一。
Cup of caution
注意咖啡的杯数
While coffee consumption may appear to be healthful for many, others should proceed with caution. Pregnant women, for example, should cautiously limit their intake of caffeinated coffee.
虽然喝咖啡对很多人来说似乎是健康的，但其他人应该谨慎行事。例如，孕妇应该谨慎地限制含咖啡因咖啡的摄入量。
"Current evidence suggests that consuming moderate amounts of caffeine up to 200 mg per day, the amount in a 12-ounce cup of coffee, is not associated with increased risks for miscarriage or preterm birth," said Dr. Joseph Wax, chair of the American College of Obstetricians and Gynecologists' Committee on Obstetric Practice. "However, data are contradictory regarding these pregnancy outcomes when women consume more than 200 mg per day of caffeine." Additionally, "there is insufficient evidence to draw any conclusion regarding the effects of caffeine on fetal growth."
“目前的证据表明，每天摄入适量的咖啡因，即一杯12盎司咖啡中的咖啡因摄入量高达200毫克，与流产或早产风险的增加无关，”美国妇产科医师学会产科实践委员会主席约瑟夫·瓦克斯博士(Dr.Joseph Wax)说。“然而，当女性每天摄入超过200毫克的咖啡因时，关于这些怀孕结果的数据是相互矛盾的。”此外，“关于咖啡因对胎儿生长的影响，没有足够的证据得出任何结论。”
If you have any heart conditions, you should also limit your coffee and caffeine consumption. "Caffeine is an aggravator and accelerator of one's heart rate," said Dr. Vince Bufalino, a spokesman for the American Heart Association and senior vice president and senior medical director of Cardiology-AMG, Advocate Health Care, in Naperville, Illinois. "Those with atrial fibrillation (commonly known as irregular heartbeat) or hypertension should limit their caffeine intake. One to two cups daily is probably fine, but if you are sensitive, you should restrict all caffeine."
如果你有任何心脏疾病，你也应该限制你的咖啡和咖啡因的摄入量。美国心脏协会(American Heart Association)发言人文斯·布法利诺(Vince Bufalino)博士说，“咖啡因是加剧和加速心率的因素。”布法利诺博士是伊利诺伊州内珀维尔的Avocate Health Care心脏病学高级副总裁兼高级医学总监。“患有心房颤动(通常称为心律不齐)或高血压的人应该限制咖啡因的摄入量。每天一到两杯咖啡因可能没问题，但如果你很敏感，你应该限制所有咖啡因的摄入量。”
Keep in mind that decaffeinated coffee still contains caffeine. An 8-ounce cup of brewed coffee can contain anywhere from 75 to 165 milligrams of caffeine, whereas decaffeinated coffee contains an average of 2 to 7 milligrams per cup, depending on which study you read.
请记住，无咖啡因咖啡仍然含有咖啡因。一杯8盎司的煮好的咖啡可能含有75到165毫克的咖啡因，而不含咖啡因的咖啡平均每杯含有2到7毫克的咖啡因，这取决于你阅读的哪个研究。
