Re: Caffeine can shorten life expectancy - but alcohol lengt
There is no confusion. The effects are as the original study described them but that in no way justifies the title of the popular press article. Caffeine shortened telomeres and alcohol lengthened them. Peat wrote about how long telomeres are associated with cancer and not with longevity. Estrogen and radiation also elongate telomeres and they certainly do not extend lifespan. Whoever chose to take the telomere effects of caffeine and beer and craft such an idiotic title should not be practicing journalism.
Just my 2c.
Look at coffee and alcohol in terms of oxidative stress. That said, Huffington Post would do anything for a bit of attention.

Hhhmm, how about tens of studies in living organisms showing caffeine dramatically increases lifespan!?! This thread I posted more than a year ago shows 52% increase in lifespan from human equivalent intake range of 600mg-1,200mg per day.

Not sure why anybody would do a "study" trying to "prove" theoretically (using a flawed idea like telomere elongation) that caffeine shortens lifespan, when it has been shown in to increase it in actual living organisms.
Btw, anything that lengthens your telomeres makes you more likely to get cancer. The few studies using extracts from the herb Astragalus known to increase telomeres bombed spectacularly after most of the animals died of cancer prematurely...
The idea of telomeres can only be taken seriously by people who believe in the Hayflick limit.

However, as Ray has said numerous times and other people (Nobel laureates) have stated as well, human cells in the right conditions are IMMORTAL!

@haidut, ncbi calls it "oxidative stress" from alcohol, do they just mean that r.o.s. are made?
LOOOOOOOL
I would not recommend using alcohol as calories though, even in healthy people. It is also estrogenic and that part cannot be avoided.
What about gut hygiene and anti-microbial properties in general? I have repeatedly seen advice in old guides to make sure to have a couple drinks with meals in such-and-such place to help avoid food poisoning. OK, alcohol is estrogenic, but what about the bugs and parasites that are also estrogenic? I mean, advice to take anti-biotics gets thrown out here like it's no biggie.
Modern cities exist because of alcohol. When sewage treatment and refrigeration wasn't "a thing" it was spirits and beer and wine that made population density viable. I think most people descendant from urbanized populations can probably tolerate alcohol fine and and probably see benefits from it. It seems to be different for people closer to a hunter-gatherer past.
I eat a "main meal" in the evening and find that one or two drinks with it definitely helps keep digestion ticking over. I wonder about the anti microbial properties.

s alcohol really an effective antiseptic in the intestines?
