Have you read the studies or the ones that disagree?
It’s been a few years now but I have. Time and time again the conclusion seems to be that the studies that say drinking is beneficial are screwing something up, eg the result is based on including very sick people who don’t drink because of their poor health, and these people die younger (and thus skew the results toward making it look like drinking increases longevity).
The studies that correct for this and other issues generally either conclude zero alcohol is best, or in one case I recall a study that concluded 5g (in other words a third of a shot, a third of a beer, or third of a glass of wine) had a minimal positive impact and by the time you got to 10g it was neutral and anything beyond 10g started reducing lifespan.
Sorry I don’t have any references. I looked into this in detail a while back and didn’t save any of what I found.
Doubtful that this is a valid objection. On the flip side, you would have to also exclude people who drink and drive because they skew mortality stats in ways that are not applicable to those who drink but don’t drive. Also, studies on benefits are not just about pure correlation with longevity but various beneficial effects.
Even excluding violent and chemical death, the third cause is cancer. Alcohol is classified as a carcinogen by IARC[1], the WHO[5] and the CDC[2]. I'm not well read on the subject - nor particularly well researched - but a cursory glance shows metabolic byproducts as the main culprit, though there are other factors.
As to "beneficial effects", keep in mind that the trace amounts of something healthy would pale in comparison to the negative effects of the alcohol, which is much less of a trace chemical.
Plus, other lifestyle choices could give a false positive[4]. Stuff like eating properly and exercising might not be properly controlled for, giving an unrealistically rosy picture.
The point about eating properly and exercising - that’s irrelevant since it’s not mutually exclusive with moderate drinking. You can drink moderately AND eat properly and exercise. The point about alcohol being a carcinogen is sort of irrelevant too since apparently it’s not enough of a carcinogen to affect longevity
