Alcohol Can Cause Irreversible Genetic Damage To Stem Cells, Says Study (theguardian.com)

A new study, published on Wednesday, states that drinking alcohol produces a harmful chemical in the body which can lead to permanent genetic damage in the DNA of stem cells, increasing the risk of cancer developing. From a report: The research, using genetically modified mice, provides the most compelling evidence to date that alcohol causes cancer by scrambling the DNA in cells, eventually leading to deadly mutations. During the past decade, there has been mounting evidence of the link between drinking and the risk of certain cancers. "How exactly alcohol causes damage to us is controversial," said Prof Ketan Patel, who led the work at the MRC Laboratory of Molecular Biology in Cambridge. "This paper provides very strong evidence that an alcohol metabolite causes DNA damage [including] to the all-important stem cells that go on to make tissues." The study builds on previous work that had pinpointed a breakdown product of alcohol, called acetaldehyde, as a toxin that can damage the DNA within cells. However, these earlier studies had relied on extremely high concentrations of acetaldehyde and used cells in a dish rather than tracking its effects within the body.

Hi,

I'm in my mid thirties, rather accomplished, with a very good job (tech) that I like, family with 2 kids etc. I drink way too much however and I fear I'm already borderline alcoholic. I've recently found this 'high functioning alcoholism' term and realized this is me. Which scares me a lot. I do know people that drink a lot in my family (I'm from eastern Europe...) and until recently I've never considered myself similar to them. For the record, I'm drinking on average 5 evenings per week, between half and a full bottle of wine (which is not that much, certainly I got used to it, so it doesn't put me in the drunk mode neither).

I keep an 'inner scorecard' which means I evaluate myself against what I used to be, and what I think I can accomplish (did I perform / accomplish something up to my potential, or did I just did a half-ass effort). Funnily enough, I always somehow discarded alcohol as a factor, justifying it (to myself) that it's not that influencing. Which is of course false. I should add that I work in the evenings very often (I love what I do btw) and most of those time, I drink too when working.

What made me realize this problem much more efficiently was running. I started quite recently and did some tests - how I perform, with the same training scheme, with and without alcohol for a period of time. Numbers don't lie. I run much better and also feel better.

As to why I'm drinking when I'm working alone, I don't really know (other than I like the taste). Not necessarily to forget problems or something. With perspective, this amounts to huge chunks of time, which certainly impacts my work on side projects / business. Sometimes I think I drink because I'm scared to actually succeed with this side stuff, and somehow unconsciously I sabotage myself.

Are / were you in this situation ? If you managed to stop, I would appreciate the 'how'.

Re:Anyone?

[hey!]

Simple answer: you need the opinion of an objective, qualified third party who has spent some time with you face to face evaluating your specific situation. What you don't need is opinions from Internet randos. Nor is it a good idea to rely on some kind of guided self-assessment. If you don't have a substance abuse problem your self-assessment would be reliable, but if you *do* then it's one of the first things to go.

Generally if something causes you distress (including worry and undue concern), and that distress does not go away on its own after a short time, that represents *some* kind of mental health problem. What you have may be a substance abuse problem, a personality disorder (like obsessive-compulsive personality disorder), or quite possibly nothing at all but a normal, passing concern. I can't tell you which it is, nor can anyone else here.

Sensationalism headline strike again!

There's a pretty huge gap between
"Alcohol Can Cause Irreversible Genetic Damage To Stem Cells, Says Study"
and
"However, these earlier studies had relied on extremely high concentrations of acetaldehyde and used cells in a dish rather than tracking its effects within the body."

Thanks but we already knew that alcoholic have an higher risk of cancer : https://www.elementsbehavioral...

But I guess I should be thankful that, for once, the real signifiant fact is inside the summary...

Just wrong.

Alcoholic drinks were a way of dealing with bad water. The use of alcohol increased lifespans.

That is was (in the case of beer, not wine) the boiling step in the preparation of the drink that provided the benefit is irrelevant. They didn't know that and never ran the experiment.

So moderate alcohol use (supposedly) helps prevent heart disease but also (supposedly) increases your odds of cancer.

On one hand, repairing or replacing hearts, possibly from cloned stem cells, is theoretically easier than curing cancer and repairing damaged stem cells.

On the other hand, a heart attack is a lot more likely to catch you by surprise before you realize you need to have your heart repaired or replaced. Also, your stem cells are going to get damaged sooner or later anyways, alcohol just speeds up the process. So sooner or later we'll have to figure out how to repair or replace stem cells anyways.

Of course that's all taking the long view. In the short(er) view, none of us are getting out of this alive. So drink up i guess?

There's a reason one should listen to scientists doing proper blind (preferably double-blind) studies over personal experience - at least mostly:
The placebo effect is very strong.

So why the "mostly" part? Because people and how they work physically and mentally can have large differences making a general study non-applicable.

Not in this case though.

I think it's complicated. They say not to drink when you have a cold/flu because it doesn't really kills germs but in actual real-life use I've found it incredibly effective at taking out these type of infections. So much so that I will sometimes take a few shots of vodka when my infected kids/grandkids/etc come to visit. I have tested not doing this versus drinking and I can say with 100% confidence that drinking makes me less vulnerable to whatever infection that is near me and often heals me faster when I'm infected.

I know, nobody outside of Russia supports this but I can say for myself it is actually true.

In my large case study of one person, me, I have found that drinking sherry helps me get over a sore throat quicker. I love the taste of sherry, but don't buy it often because of the alcohol. I had sherry one time when I had a sore throat and felt better the next day, so now every time I get a sore throat I drink sherry. Seems to help, but my evidence is no better than Chinese folk medicine, or other untested techniques.
