There is no “should” drink recommendations for alcohol, but health benefits have been associated with moderate alcohol consumption (2 drinks/day for men; 1 for women). The benefits of moderate alcohol consumption include reduced risk of heart attack and stroke; increased HDL (good cholesterol) and reduced blood clotting, which is probably the reason for a reduction on heart attacks and strokes. Additionally, just recently moderate alcohol consumption was connected to a lower risk of developing type 2 diabetes, gallstones and cognitive decline. The downside is that moderate drinking can lead to excessive drinking that is not just extremely detrimental to YOUR health but also to the health of people around you. So keep it moderate or don’t drink.
One drink contains 14 grams of alcohol, meaning one 12 oz beer (5% alcohol), one 5 oz glass of wine (12%), and one 1.5 oz of hard liquor (40% or 80 proof) are each one drink. It does appear that alcohol itself, and not the source, is responsible for the benefits.
