It's a fucking shame I became allergic to coffee!

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.

[-] jeff@programming.dev 8 points 15 hours ago

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:

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?

[-] reabsorbthelight@lemmy.world 3 points 7 hours ago

And if you drink 300 cups of coffee in a day. Your dementia risk is 0%!!!

[-] LodeMike@lemmy.today 5 points 22 hours ago

A day. Not at a specific time

[-] Crozekiel@lemmy.zip 4 points 4 hours ago

Correct, 3 cups of coffee in a single day would absolutely wreck my system. :(

[-] TehWorld@lemmy.world 2 points 12 hours ago

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?

[-] Tollana1234567@lemmy.today 1 points 13 hours ago

also associated with lower blood sugar somewhat too.

[-] Elting@piefed.social 22 points 1 day ago* (last edited 1 day ago)

2-3 cups of coffee a day gives me a headache and diarrhea.

[-] HeyThisIsntTheYMCA@lemmy.world 1 points 2 hours ago

that seems like an indication that you personally shouldn't do that.

2-3 cups of coffee is good for me. kind of why taking medical advice over the internet is a bad idea. everyone's gut is wildly different.

[-] ikidd@lemmy.world 11 points 19 hours ago

From low caffeine, right? Me too.

[-] BeigeAgenda@lemmy.ca 26 points 1 day ago

See you didn't get dementia, I call that a success!

What were we talking about?

[-] Doug@piefed.social 20 points 1 day ago

Higher tea intake showed similar results, while decaffeinated coffee did not β€” 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 πŸ˜”

[-] southsamurai@sh.itjust.works 1 points 18 hours ago

I feel that!

[-] Elting@piefed.social -1 points 22 hours ago

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.

This study brought to you by Charmin

[-] SkaveRat@discuss.tchncs.de 6 points 1 day ago

If only I wouldn't keep forgetting

The caffeine makes you active and seek mental challenges.

[-] SaveTheTuaHawk@lemmy.ca 1 points 1 day ago

ok, now do the proper controlled study comparing coffee to any other stimulant.

Stimulants like caffeine improve scores in cognition assays. Another πŸ’© 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?

[-] SaveTheTuaHawk@lemmy.ca 2 points 2 hours ago

That is not new, caffeine is an analog of ATP and known to affect serum cholesterol levels in the liver. Welcome to 1996.

Epidemiology is a fucking joke. We waste millions on studies making the same observations over and over then the media treats this like it's profound and new.

How many studies do we need to show obesity makes every disease worse or more prevalent?

How the fuck did they even control this study? Most people consume caffeine in one way or another. The one exception is Mormons, who actually have less disease than the typical population so this πŸ’© can seriously fuck off and stop wasting money.

[-] chisel@piefed.social 0 points 23 hours ago

Maybe 100% of the positive-caffine-outcome people also snorted 100mg of adderall every morning?

[-] SaveTheTuaHawk@lemmy.ca 1 points 2 hours ago

Exactly. Stimulants improve test scores, which is why most students are on adderol one way or another.
