I'd chided the NZ Heart Foundation for ignoring the cardiovascular benefits of moderate drinking in their heart-health calculator. In comments over at SciBlogs, the Heart Foundation said why:
reasonable list of recent articles demonstrating clear cardio benefits of moderate drinking.
Vox this week summarised the literature and reached the same conclusion I did. There are clear cardiovascular benefits from light to moderate drinking. Here's their article and their research summary. I'll note that when they say that there's increased risk after a drink a day, that's increase relative to the point where the health benefits are strongest. If you're looking at all-source mortality risk and comparing to a non-drinking baseline, there remain net health benefits up to about 3-4 standard drinks per day - beyond that, and there's increased risk.
