"The Doll and Peto study of 1994 [...] demonstrate[s] thatdrinking 10-15 units [of alcohol] a week is associated with reduced mortality, and that it is not until consumption rates reach 60 units a week that the mortality matches that of teetotallers.
Alcohol reduces thrombogenesis, something that reduces the risk of heart attacks, and some products like red wine contain antioxidants and resveratrol, which has been linked to increased longevity."
"CONCLUSION: The consumption of alcohol appeared to reduce the risk of ischaemic heart disease, largely irrespective of amount. Among regular drinkers mortality from all causes combined increased progressively with amount drunk above 21 units a week. Among British men in middle or older age the consumption of an average of one or two units of alcohol a day is associated with significantly lower all cause mortality than is the consumption of no alcohol, or the consumption of substantial amounts. Above about three units (two American units) of alcohol a day, progressively greater levels of consumption are associated with progressively higher all cause mortality."
