Marked differences between caffeinated, decaffeinated drinks in analysis of more than 130,000 people
So is tea.

Maybe there is something more here, but I’m always skeptical of these studies that are more likely explained because of wealth indicators or another confounding factor, like the red wine study from like 20 years ago.
Is it possible that people that drink 2-3 cups of coffee are more likely to have an office job, which is more likely to be intellectually demanding, which decreases risk for dementia. And if you drink decaf you are more likely to have another neurological disorder that increases dementia risk.
Having worked in factories, the coffee in them is usually the strongest and always available, Blue collar lives on the stuff,
I was about to day, my blue collar granddad who died of dementia drank coffee until he wasn’t sentient enough to lift the mug to his mouth.
Yeah, I’m not claiming that’s actually the reason, just an example of these correlations aren’t always straightforward.
Me, 8 cups of coffee deep by 9AM, shitting my guts out, listening to two podcasts, responding to a slack thread, and shitposting at the same time, knowing I won’t get dementia:

also associated with lower blood sugar somewhat too.
If I drank 3 cups of coffee, I would be able to see my pulse. But I guess if I die of a heart attack at 50 then I am much less likely to get dementia?
And if you drink 300 cups of coffee in a day. Your dementia risk is 0%!!!
A day. Not at a specific time
Correct, 3 cups of coffee in a single day would absolutely wreck my system. :(
Lol. I often drink 3 cups of coffee before leaving for the office, where I usually drink a big mug-o sludge. At one point I was drinking a full 12 cup pot daily.
Do you pee every 2 minutes?
2-3 cups of coffee a day gives me a headache and diarrhea.
From low caffeine, right? Me too.
See you didn’t get dementia, I call that a success!
You don’t know that.
Don’t know what?
What were we talking about?
Higher tea intake showed similar results, while decaffeinated coffee did not — suggesting that caffeine may be the active factor producing these neuroprotective results, though further research is needed to validate the responsible factors and mechanisms.
I have caffeine sensitivity and only drink decaf so uhhhh fuck me I guess 😔
I feel that!
Decaf is pretty comparable to some kinds of tea in terms of caffeine content. I know when I make decaf it has way more caffeine than when I make black tea.
As funded by big coffee?
It’s called a grande sweety 💅💅💅
This study brought to you by Charmin
If only I wouldn’t keep forgetting
The caffeine makes you active and seek mental challenges.
ok, now do the proper controlled study comparing coffee to any other stimulant.
Stimulants like caffeine improve scores in cognition assays. Another 💩 study.
The primary outcome was dementia, which was identified via death records and physician diagnoses.
If caffeine has enough of an effect to change a diagnosis or death record, that seems worth reporting in any case.
And while it might be worthwhile to see if other stimulants have a similar effect, does it affect these results one way or the other?
Maybe 100% of the positive-caffine-outcome people also snorted 100mg of adderall every morning?
