Funded by the Institute for Scientific Information on Coffee (ISIC) — an industry body — which is a notable conflict of interest the authors disclose but don't extensively discuss

It does not sound like an outcome that big coffee paid for it to be so: Behaviourally, coffee drinkers exhibited greater impulsivity and emotional reactivity, whereas non-coffee drinkers demonstrated better memory performance.

Do they though? Any data on that? Also, the highly caffeinated people might also be sleep deprived, which impacts memory and emotional regulation

After habitually consuming caffeine (not in coffee form) daily, usually multiple times a day, for more than a decade, a horrible mental health incident happened to me that forced me to stop it for a while. Afterwards I didn't resume the habit, and so I no longer have a tolerance. This has let me evaluate what caffeine does with fresh eyes, so to say, because I can now consume it occasionally while having many non-caf…

How do you know that caffeine was the cause?

What's cool is this effect exists even in decaf coffee, as someone who primarily drinks decaf black, for flavor and for a good night's rest as I'm sensitive to caffeine.

What kind of decaf coffee do you drink? There are differences between the cheap chemical Methylene way to create decaf coffee and the expensive co2 way to get rid of the caffeine. https://cleanlabelproject.org/wp-content/uploads/CLP-Decaf-C...

Is that methylene way even legal? It basically uses petroleum fuel in the process right? I assume it was outlawed a long time ago but that might be extreme naievete for US regulatory capability...

This of course cannot be generalized, but withdrawal is quite noticeable for personal well-being in a positive way.

The only good thing that keeps me from collapsing into a state of limbo is coffee and now, even that's bad (seems more like a mixed bag, but still)? Sigh.

Coffee in general is unreasonably healthy as a beverage. The overwhelming majority of science agrees it’s a quality health drink.

Non-industry funded science?

I’m super interested in this sort of study! However, it looks like n=62 here, which I think weakens the results —they’re probably just useful as suggestions of possible effects. Also, any food is expected to have similar effects on the microbiome. They didn’t test caffeine in isolation. In some ways that’s better (I don’t consume caffeine in isolation), but in some ways that’s less useful (it’s possible you get simil…

In 1995, NASA did spiders experiment. Caffeine is a siginificant impulsivity trigger. :) https://rarehistoricalphotos.com/nasa-spiders-drugs-experime...

LSD has unconnected strands in the air. I guess this is expected.

Earlier quoted context omitted.

I was so surprised at this headline that I nearly leapt out of my chair!

But it says it’s the same for decaf. That is more interesting

Been treating coffee as caffeine with aroma. Any important points about coffee itself?

Notably, the article is looking at coffee, both caffeinated and decaffeinated. There is a lot more to coffee than just caffeine...

The overwhelming majority of the enjoyable coffee experiences are caffeinated. While there is good decaf out there it's not the norm, specially in smaller markets.
