平时，基本上每天两杯咖啡。一为爱好，二则提神。至于朋友们说我的“小资情调”，倒在其次。 今天，从邮箱订的电子刊物刊登：Coffee May Cut Risk of Prostate Cancer（咖啡能够降低前列腺癌风险）。倍受鼓舞。我想这对于喜欢喝咖啡的男性朋友是一个非常好的消息。 其实，此前也看到类似的研究，声称咖啡能够降低妇女乳腺癌的发病率。 所以，正如喝茶，赞同的人很多，无非茶叶中所含多酚类物质有助于抗衰老（就是抑制自由基产生）。这些都是统计的结果。我个人认为，此类爱好，除非公认有害健康，没有必要刻意去戒除。 下面是这篇报道原文： Coffee May Cut Risk of Prostate Cancer from WebMD — a health information Web site for patients December 8, 2009 — Drinking coffee regularly may help lower the risk of advanced prostate cancer, a study shows. The study, presented this week at a conference of the American Association for Cancer Research in Houston, shows men who drank the most coffee were nearly 60% less likely to develop advanced prostate cancer than non-coffee drinkers. Researchers say it's too early to start recommending that men start drinking coffee to help prevent prostate cancer, but the results are encouraging. "Very few lifestyle factors have been consistently associated with prostate cancer risk, especially with risk of aggressive disease, so it would be very exciting if this association is confirmed in other studies," says researcher Kathryn M. Wilson, PhD, a postdoctoral fellow at the Channing Laboratory, Harvard Medical School and the Harvard School of Public Health, in a news release. "Our results do suggest there is no reason to stop drinking coffee out of any concern about prostate cancer." Researchers say it's the first study of its kind to look prospectively at both the overall risk of prostate cancer and the risk of localized vs. advanced prostate cancer that has spread beyond the prostate. In the study, researchers analyzed information from the Health Professionals' Follow-Up Study, which included data on the coffee-drinking habits of nearly 50,000 men from 1986 to 2006. During that time period, 4,975 of the men developed prostate cancer. The results showed men who drank the most coffee (six or more cups per day) had a 59% lower risk of aggressive prostate cancer (fatal or advanced disease) compared to non-coffee drinkers. But researchers say it's not just the caffeine that's responsible for the prostate cancer prevention benefits. The study showed men who drank decaffeinated coffee also had a similar reduction in aggressive prostate cancer risk. Researchers say coffee also contains many other potentially beneficial compounds such as antioxidants and minerals that may play a role in preventing prostate cancer and more research is needed to confirm these results. "Coffee has effects on insulin and glucose metabolism as well as sex hormone levels, all of which play a role in prostate cancer," says Wilson.
