[00:05.64]Today we have more good news for all our coffee drinkers around the world. [00:12.08]Another new study finds that drinking coffee can help you live longer. [00:18.56]Researchers at the Harvard School of Public Health [00:21.88]recently discovered that drinking between three and five cups of coffee a day [00:27.88]may prevent certain illnesses. [00:31.08]They found that coffee can protect against heart disease, [00:35.24]brain diseases, type 2 diabetes and suicide. [00:40.48]Walter Willett is a nutrition researcher at Harvard and co-author of the study. [00:47.36]Willet says the findings extend to both caffeinated [00:52.00]and decaffeinated coffee – or decaf, as Americans often call it. [00:57.88]So, the health benefits come not just from the caffeine in coffee, [01:02.96]but from the compounds in the beans. [01:06.60]The large study of about 200,000 subjects [01:10.44]included data from three ongoing studies. [01:14.60]Subjects in the study had to answer questions about their coffee drinking habits [01:20.52]every four years over a 30-year period. [01:25.48]Researchers found that moderate coffee drinking [01:28.84]was linked with a reduced risk of death from many diseases. [01:34.00]These diseases include cardiovascular disease, [01:37.76]diabetes, neurological diseases such as Parkinson's, and suicide. [01:44.80]However, the researchers found no link between coffee drinking and cancer. [01:51.08]Researchers also considered other habits such as smoking, [01:55.36]obesity, and how active the subjects were. [01:59.88]They also looked at what kinds of food the subjects ate, [02:04.20]as well as how much alcohol -- and what type of alcohol -- they drank. [02:09.52]They published their findings in the journal Circulation. [02:13.48]This Harvard research adds to a growing body of evidence. [02:18.44]This body of evidence finds drinking a moderate of coffee [02:23.16]may have many health benefits, including a longer life. [02:27.64]This is according to one of the researchers involved in the study. [02:32.24]Frank Hu is senior author of the study. [02:35.44]He is also a professor of nutrition and epidemiology. [02:40.65]He studies how food affects illness. [02:44.40]Hu adds that data from the study support the 2015 Dietary Guidelines Advisory Report. [02:53.96]This report found that drinking a moderate amount of coffee [02:57.72]can be part of a healthy diet. [03:01.16]But how much and when you drink coffee is important. [03:05.28]You may remember another study we reported on recently. [03:10.15]That study said drinking coffee too late in the evening [03:14.40]can disrupt your sleep. Questions [03:16.44]Not everyone feels the recent Harvard study confirms anything. [03:21.80]The news organization NPR spoke with one expert [03:26.52]who warns that not everyone reacts to coffee the same way. [03:32.04]Andrew Maynard of Arizona State University [03:35.88]told NPR that the health benefits documented in this new study are "small." [03:42.96]Maynard says the study does not prove cause and effect [03:47.12]between drinking coffee and living longer. [03:50.92]He says the study points to an association, [03:54.60]or link, between drinking coffee and living longer. [03:58.79]Even those involved in the research still have questions. [04:03.36]When NPR spoke with study co-author Walter Willett, [04:07.64]he said he is not sure how coffee is linked to certain health benefits. [04:13.36]Willett says the take-home message – in other words, the important thing to learn [04:18.56]– is that if you like coffee, do not feel guilty about drinking it in moderation. [04:24.96]If you don't like coffee, don't feel you have to start drinking it to be healthy. [04:30.72]I'm Anna Matteo. [04:32.04]更多听力请访问51VOA.COM
