There has not been a large amount of research into prostate cancer and
alcohol consumption. However, the studies that have been undertaken
suggest a mixed picture. There is one study which suggests that there
could be an increased risk from the consumption of spirits, whilst
others suggest that there are no clear associations with beer or
spirits.
Of particular interest has been red wine, with one research study
finding that a moderate consumption of red wine had a protective
effect, and another showing that there did not appear to be a link
between drinking red wine and prostate cancer. The study showing a reduced
risk suggests that this may
be because of a compound called reservatol, which is a strong
antioxidant. This does not mean, however, that men should increase
their consumption of red wine, as drinking too much can have other
health effects including on the liver and increasing the effects of other
diseases.
