A 2012 study review found that people who drank moderate amounts of wine or beer had a 42% lower risk of heart disease than non-drinkers. ... Beer contains B-vitamins, including vitamin B12, folate, niacin, riboflavin, and vitamin B6. These brain-boosting nutrients mean beer provides more than just carbs and calories. Beer is conspicuously absent from these health bulletins, but it too contains a fair share of polyphenols and seems to offer modest benefits, akin to white wine but less than red wine. Clearly, none of this gives you a free pass to binge drink, but if drank in moderation, a glass a day really may keep the doctor away.
