Have there been studies of nominally non-drinking sub-populations, such as Mormons or Muslims, to understand the effects of alcohol?

The increase in alcohol usage in a population increases the onset of symptoms of various alcohol related health effects, including alcoholism and death.

It’s pretty well understood, clinically speaking.

But it’s fun to down a few and the statisical chances of dying sooner are not that high if you follow the generally recommended limits.

Yes, but those populations are far from completely dry. They may drink less, but do not represent a scientific control group. If you did find a totally dry community, the other cultural differances may well muddy the results too (diet, relationship to medical care etc).

They never include the mental benefits of alcohol. A night out drinking with friends or coworkers has mental health benefits that last, sometimes a lifetime.

In your experience, is the alcohol required to enjoy the night out? I've personally had nights out with and without alcohol that were just as much fun. I'm also very much a homebody though, so I'm not a great sample to really say either way.

It’s not required, but so much of socializing and the existence of various “third places” hinges on alcohol that the choice is “do something social centered on drinking” or “do nothing”. You can’t expect people to single handedly overturn the social systems that have intertwined alcohol and socialization (especially for men)

At the army, I remember a doctor insisting on a very precise answer to the question if I was drinking alcohol "never" or "rarely".

for coffee it's probably very similar

we say "the dose makes the poison" but it doesn't change that regularly drinking a low dose of poison is not good.

They have other diet restrictions and lifestyle, which might have other effects on life expectancy

If it's required you shouldn't drink. Alcohol is only good when you don't need it.

Here’s one of the fundamental problems with studying human diet and psychology, from the article: > The best way to assess the effects of alcohol would be to randomly assign people to drink it or not in childhood and then monitor their health and drinking over the rest of their lives. Since such studies cannot be done, researchers instead have to ask people about their drinking habits and follow them over much shorte…

The other being the myriad of influencing factors you can never really isolate.

Say you do the setup from the quote, then one group would also be in a special situation where researchers told them to do this thing, and they would tell their friends, or maybe they would keep it secret, or maybe it would make them a bit weird, or maybe it would pave the way for more addictions, or make them more conscious of it, and they would have another item on their usual shopping list, and they may meet their spouse in a bar, and so on — all of which influences outcome.

Ethanol is metabolized to acetaldehyde. Aldehydes form crosslinks between proteins and DNA (and DNA with itself). Inactivation of the aldehyde-metabolizing ALDH2 enzyme (which happens in 50% of East Asians) increases risk for various disorders including cancer and late-onset Alzheimer's.

Acetaldehyde is also be metabolized by the brain for energy. May be why some people get so addicted.
