A lower incidence of prostate cancer in men who drink coffee is the focus of a newly released study conducted at Harvard university. The 22-year study looked at groups of men who drink either regular or decaffeinated coffee, and from 1986 to 2008, the men were asked to report their coffee consumption. The researchers discovered that the men who drank the highest amounts of coffee on a regular basis had the lowest percentage incidence of prostate cancer, and were 60% less likely to die from the disease. According to the study, those who benefited from the decreased risk were those who drank at least six cups of coffee per day. Those who drank up to three cups per day were 30% less likely to die from prostate cancer than those who did not drink coffee at all or drank it on an irregular basis.
The researchers, however, have noted that it is not advisable for men to go out and start drinking massive amounts of coffee based on one study, and that further research will be necessary in order to come to a more validated conclusion about the complex series of factors responsible for causing prostate cancer. One thing the results of the study did not explain was why coffee might contribute to lower prostate cancer numbers. Researchers have speculated that it may have something to do with antioxidants, or with coffee’s insulin-regulating compounds.
Although this most recent study is likely to cause quite a stir amongst the male population, this is not the first time Harvard researchers have linked coffee to health benefits. In previous studies conducted at Harvard, coffee was also shown to reduce the risk of liver cancer and Parkinson’s disease, and coffee drinkers were also shown to be less likely to develop type II diabetes.
