According to a Spanish study, drinking alcohol equivalent to 28 pints of beer per week can decrease the chance of heart disease. The results showed that the benefit was greater for men than women. This study was published in Heart, a peer reviewed medical journal. You can read the abstract here.
Of course there are countless other studies which show the reverse is true. Bottom line, drink in moderation and you may live.
