When we parametrize complex systems in studies such as this, I feel we tend to lose the forest for the trees. Okay, so maybe 25 cups of coffee a day won't destroy my heart. But this is what happens when I have 5 cups of coffee a day: 1) I get jumpy and I feel anxious. If I drink too much I start to feel what I can only describe as existential dread (I know it's weird). 2) I can't hold on to things because my hands ar…

I think the point here is that people with heart disease needn't worry too much about coffee/caffeine intake. Heart disease affects a large part of the population and even among those who are not effected heart health is still something to be conscious of, especially in middle and old age.

Agreed, they're not condoning or advocating for high consumption. They're simply establishing that even when drinking absurd amounts of coffee you're not at increased risk, therefore it is ok to drink coffee.

Also, studies like this don’t how it’s heathy, they simply fail to demonstrate significant harm over the course of the study which is a very different thing.

That is wrong, what they say here is that arteries may not suffer by drinking coffee. But there is a lot of evidence pointing that all sorts of arythmias can be connected to caffeine intake...

> If I drink too much I start to feel what I can only describe as existential dread (I know it's weird). Not weird at all. It’s that free-form, nameless, unspecified anxiety.

+1 here. I can't describe it, but it's like a feeling that I'm about to die, that everything is about to end. Needless to say, it's not pleasant.

I've only drank coffee a total of probably six times in my life. I seem to be getting by just fine without it.

It’s a great performance enhancer if you take it rarely enough, and it’s entirely legal to use at academic competitions :)

A few years ago I just decided to give up caffeine entirely. It wasn't worth the impact on my sleep or the stop-everything-and-find-caffeine headaches I got. I became uncomfortable with the fact that, in some small way, a substance exerted that much control over my life.

I almost spit out my coffee upon reading "25 cups of coffee a day" -- wait, what!? Then I read the OP... and yes, it turns out there are people who routinely drink that much coffee in the UK. Wow. Can you imagine what one's body would feel like after ingesting 25 -- twenty five -- cups of coffee in a 24-hour period?[a] [a] Assumes zero hours of sleep per day.

It's actually not exactly that inconceivable if the you're using the traditional 5 fl oz cup size for tea/coffee.

I've just finished my morning coffee - a 34fl oz French press's worth, black. That's almost 7 "cups" by traditional measure, but it's not a particularly outlandish amount.

This was a longitudinal study that which controlled for blood pressure. What about people for whom habitual heavy coffee consumption causes high blood pressure? The study just looked at MRI heart scans. This sort of interaction won't show up in that setting.

25 cups of coffee in a day sure seems like an unhealthy amount of caffeine. it seems the only factor they were checking for (?) was arterial stiffness? if you're arteries aren't stiff but you're hyped and anxious out of this world and have a very elevated heart rate... not sure the stiffness is what matters anymore 1 cup typical drip coffee = ~70-120mg caffeine 25 cups = ~1750-3000mg caffeine Examine ( https://examin…

British study. We can infer instant coffee was the main preparation recorded in the study, which has a lower caffeine content than fresh brewed.

~70-120mg look like drip brew numbers. Instant tends to run from 30-50mg.

25 cups of instant == ~750-1250mg
