Coming from Harvard University is the latest news, published in the Journal of the National Cancer Institute, on the benefits given by coffee consumption. In fact, a 20-year-long study (1986-2006) monitored about 45 thousand American men and found that a large number of daily cups consumed corresponded to a 20 percent reduction in the risk of any type of prostate cancer, and an even more dramatic drop (around 60 percent) in the risk of contracting the most common (and deadly) form of cancer for men.
The volunteers were all health care workers, and throughout the study period they had to report their daily habits related to coffee consumption. Their tests showed that drinking at least 6 cups a day resulted in a reduced risk of prostate cancer.
However, the link between coffee and prostate seems to depend not on caffeine (because the research participants got the same results whether they drank regular or decaffeinated coffee) but on antioxidants and other chemicals present in coffee. These, would affect both the method by which the male body processes sugars and the levels of sex hormones, the two factors most linked to the development of prostate cancer.
It should be emphasized that since this research was conducted in the United States, it should be kept in mind that these people are used to drinking really long coffees, the classic Starbucks-style cups; therefore, I am afraid that if we want to convert these six American cups into cups of espresso for Italians, we have to consider a really high amount of cups.
