Drink Coffee to Reduce the Risk of Prostate Cancer

Prostate exams are actually not this bad...as long as you don't ask a bull to do it.
Coffee contains diverse biologically active compounds that include caffeine, minerals, and phytochemicals. In previous studies, coffee consumption has been consistently associated with a reduced risk of type 2 diabetes, and its effects on insulin, sex hormones, and antioxidants may also be relevant to prostate cancer.

However, epidemiological studies of coffee consumption and prostate cancer have generally reported null results, although most lacked a wide range of coffee intakes and a large number of case subjects and none specifically examined advanced disease.

Therefore, the authors of this new study sought to avoid the pitfalls of previous studies, and hypothesized that coffee may be associated with lower risk of more advanced prostate cancers because the associations of insulin, antioxidants, and androgens.

They conducted a prospective analysis of 47,911 men in the Health Professionals Follow-up Study who reported intake of regular and decaffeinated coffee in 1986 and every 4 years thereafter. .

The average intake of coffee in 1986 was 1.9 cups per day. Men who consumed six or more cups per day had a lower relative risk for overall prostate cancer compared with nondrinkers, and this association was stronger for lethal prostate cancer.

The inverse association with lethal cancer was similar for regular and decaffeinated coffee (indicating it isn't the caffeine that offers the protective benefits, which was the case in another study on coffee for Alzheimer's disease I covered in the past).
