> Both groups reported lower perceived stress, depression and impulsivity scores after coffee was reintroduced
This is a terrible sentence. As I understand it, you can't "reintroduce" coffee to non-coffee drinkers.
Caffeinated and decaffeinated coffee lower stress, depression and impulsivity

#32Any mood or depression study without a control group is, unfortunately, useless. There is an interesting effect in mood related studies where every group usually improves on average, even if they receive only placebo. The real measure of any depression study is therefore the improvement above and beyond the control group. The effect is so predictable that it has become an easy way to produce studies showing positive…
Also, for anyone who ever tried to quit coffee, probably knows this— the period of feeling down, useless, slow, and tired after you quit is brutal for about 1-2 weeks and can last months for long-time coffee drinkers. No wonder people feel great after having coffee again. And decaf is not caffeine-free. Decaf coffee still contains about 5-10% of the original caffeine content compared to the same beans but not decaffe…
I needed to quit drinking caffeine and my wife decided to just start transitioning me onto decaf without telling me, each week mixing a little more into the regular coffee bean cannister until it was basically 100% decaf. It worked really well, as I didn't find out I'd been drinking 100% decaf until she told me about it.

I've quit from daily 3-4 shots of espresso to only drinking it when I feel like it, which is about once every two weeks.
The process was mostly without discomfort: I bought decaf beans and started cutting my coffee grounds with 50% decaf. After two weeks, 75% decaf. Then 87.5%, etc. About two months later I stopped experiencing withdrawals if I don't drink any coffee at all.
Before I started cutting I would get massive headaches and become irritable if I don't drink coffee in the morning. Now I'm free!
I encourage all heavy coffee drinkers try drinking less. At some point, it stops improving your cognitive functions but instead just maintains a mediocre baseline, which I suppose is the same as almost all substance reliance.

#35Anecdotally, multiple folks have said to me they don't drink coffee because it makes them anxious. Enough for me to take notice.
The journal article actually touches on that:
>In CD participants, indoles such as indole-3-propionic acid (IPA) and indole-3-carboxyaldehyde (ICA) and the neurotransmitter γ-aminobutyric acid (GABA) were significantly decreased.
GABA is an anti-anxiety neurotransmitter, it's what benzodiazepines mimic.

It's almost like having someone interested in your mental health (even if only to track it) is good for it?
This effect occurs even in non-mental health related studies.

#37Is this real, or is this a green jelly bean - https://xkcd.com/882/. Since most Americans (likely including you, though in some countries tea is more popular) are addicted to coffee they like to boost anything that makes their addiction seem like a good thing.

#38I love coffee, I take 2 to 3 every day (Italian espresso, so very short, little total caffeine), however for some reason taking the decaffeinated one in the evening interferes with my sleep in a similar way than the caffeinated one. Any hint?

I noticed from reading threads online that I can drink 8 espressos a day and stop having espresso for several days or weeks. I make my own from ground beans of 18g. It does nothing to me, I never felt a stimulation and only taste guides my need. If I don’t like the taste even offered in restaurant I will refuse to drink it.
I don’t know why I’m like that but I never understood the discomfort phases and the stimulation ones either. Idk if I’m missing something

I agree with all your points, it just leads me to this question: How did this get published in Nature Communications? Surely these are the first things raised by peer review.
