English Corner│咖啡健康新功效：预防动脉钙化

2016-12-08 Coffee drinkers, you can continue to feel good about drinking coffee. This is what a new study out of Korea is indicating and how coffee could protect against cardiovascular disease. This is very good news considering coronary artery disease affects almost 16 million Americans. It is estimated that 54% of Americans over the age of 18 drink coffee every day. 科学家们又给我们喝咖啡找到了一个新理由！近日，一支来自韩国的专家团队对咖啡对心血管健康的影响进行了专项研究。如今，心血管疾病威胁着约1,600万美国居民的健康，与此同时，据统计，约54%的美国成年人（年龄在18岁以上）每天都喝咖啡。 More than 25,000 participants without symptoms of heart diseaseand with an average age of 41 were analyzed. The majority of those in the research were men who averaged 1.8 cups of coffee daily. Out of the study group, 13.4% had signs of some calcification. Calcification refers to specks of calcium found in the walls of the coronary arteries and is considered an early signof coronary heart disease. 共有超过25,000名未发现心脏病症状、年龄在41岁的志愿者参与了该项研究，其中大部分为男性，每天咖啡饮用量为1.8杯。在被研究对象当中，有13.4%的人出现了血管钙化迹象，血管钙化是指心血管壁出现的钙化斑块，被认为是心血管疾病的早期症状。 What the research found was that participants who consumed an average of three to five cups of coffee a day had the least amount of calcification. A “dose-response” pattern was found meaning that the risk for coronary artery disease fell as cups of coffee consumed rose from one cup a day to three cups to five cups. But, once the amount of coffee was more than 5 cups a day there was a higher riskfor coronary artery disease than the moderate drinkers. 研究显示，每天喝3-5杯咖啡的人出现血管钙化迹象的几率最小，且趋势表明，人体患心血管疾病的风险会随咖啡饮用量的增加而降低，尤其是在每天1杯至每天3-5杯这一区间内更为明显，但一旦饮用量超过5杯，人体患心血管疾病的风险反而会增加。 This new study published in Heart, explains that coffee consumption has been linked to improving insulin sensitivity and reducing oxidation of LDL (bad) cholesterol. This is important since oxidation makes calcification more dangerous. 该研究成果被刊登在《Heart》杂志上，该文章的发表向人们揭示了咖啡师如何提高胰岛素敏感度、降低低密度脂蛋白氧化的。据专家称，低密度脂蛋白的氧化会使血管钙化更加危险。 There was no differentiation between whether the participants consumed regular ordecaffeinated coffee. 此外，结果显示，饮用普通咖啡和无因咖啡的效果完全相同。 This study was found to be helpful since there is not much previous information on theconnection between coffee consumption and coronary artery calcification. It also ties in with the 2015 Dietary Guidelineswhich addressed the safety of coffee for the firsttime. In that report, the guidelines concluded that drinking between three to five cups of coffee daily (up to about 400 milligrams of caffeine) was associated with minimal health risks. In addition, observational studies have indicated that drinking coffee is associated with lowering the risk of type 2 diabetes and cardiovascular disease. 该研究成功的意义在于，此前人们很少将咖啡和动脉钙化联系在一起。这份研究同时为《2015年美国饮食指南》中对咖啡安全性的论述提供了重要依据。指南指出，每天喝3-5杯咖啡能够使咖啡的健康功效最大化，此外，还有研究显示咖啡能够降低人体患二型糖尿病和心脑血管疾病的风险。 The researchers noted that if a person currently does not consume coffee there are other healthy beveragesto choose from such as water and tea. Just remember to not turn your coffee habit into more of a coffee milkshake habit overloading it with too muchcreamand sugar– then you’ll be defeating the purpose. 研究者最后补充道，除咖啡以外，人们还可以选择水和茶等健康饮品。请记住，喝咖啡时不要加入奶油和过量的糖，否则会抵消掉咖啡的健康功效。 文章来源： http:///food-and-diet/coffee-reduces-artery-clogging-plaque 第9期杂志阅读处 |
