The habit of coffee drinking in women has been shown to reduce the risk of breast cancer. Recently, a study again revealed that the hobby of drinking coffee is also beneficial for men that is to prevent diabetes and prostate cancer.

Kathryn Wilson, a researcher from the Harvard School of Public Health in Boston revealed that certain compounds in coffee may affect the function of insulin. This hormone plays a role in sugar metabolism is disrupted and if function can trigger diabetes or diabetes.

According to Wilson, many previous studies also revealed that insulin has a relationship in men with prostate cancer risk. If the impaired insulin function, so in addition to trigger diabetes in men it is the additional risk of prostate cancer.

To prove it, Wilson’s observation on 48,000 men for 22 years since 1986. Quoted from HealthDay, Wednesday (5/18/2011), Wilson checked every 4-year prostate condition of the participants and ask a few things about diet and coffee drinking habits.

Until around 2008 when the study ended, there were 5035 participants eventually get prostate cancer. Of these, 642 of whom have entered the metastatic stage, which means cancer cells have spread to other tissues to the surrounding areas.

The results showed, the risk of prostate cancer in participants who drank 6 cups per day of coffee or more reduced by about 20 percent. Even after adjusting for other factors, the risk of metastatic prostate cancer stage was reduced by 60 percent.

Prostate cancer risk was also reduced in participants who diligently drinking coffee, even if the amount is up to 6 cups a day. Enough with 1 to 3 cups a day, stage metastatic prostate cancer risk can be reduced to 30 percent.

Wilson acknowledges, this study has not succeeded in identifying the specific content of coffee that have influenced the results of his research. But he was sure, was not the caffeine content because the benefits are relatively equal when tested with decaffeinated coffee (caffeine free).
