Is this just related to caffeine, or coffee in general? I drink a LOT of decaf, which probably ends up being 2-4 cups of "real" coffee.

Re: High coffee consumption, brain volume and risk of dementia and stroke
#42I can't access the article. Can somebody tell me what is "a cup" mentioned in the article? How much water and how much caffeine is in one "cup" in this article? All the comments here mentions different number of "cups", but I'm very worried that all are different "cups"
I've looked for this, the BioBank screen is this: https://biobank.ndph.ox.ac.uk/showcase/refer.cgi?id=100319 There is literally no guidance AFAICT. My best estimate is 8 US fl oz as per ChatGPT British still use cups to refer to that sometimes. And caffeine... it varies even from cup to cup, the estimate of 91mg per 8 oz cup is what I use.

#43A cup of coffee can be something very different from person to person and situation to situation. Espresso? Weak americano? Strong? And then even: there is often more caffeine in a cup of filter coffee than in an espresso. Weird but true. So it differs quite a lot what you drink. I know someone who drinks 15 cups a day, but they are very very weak. And another drank 20 stong ones a day. Myself I used to drink 10 easi…
Even the same volume(cup) of coffee brewed the exact same way will vary in caffeine content based on whether it's a light or a dark roast. I wish more studies like this would just list mg of caffeine for comparison instead.

Sci-Hub link[1] to the paper.
I think it's safe to conclude that a cup here is in UK terms:
> Individuals aged 37–73 years were recruited in 22 assessment centres across the United Kingdom, between 13 March 2006 and 1 October 2010.

#46Earlier quoted context omitted.
The scientific definition of a 'cup' of coffee is important. Usually this is defined as 4 ounces of brewed coffee, which means a normal mug of coffee (which can fit something like 10 oz) would be 2.5 cups! So, for most people's definition of a 'cup' of coffee, they really only mean 2.5 'mugs' of coffee.
And surely the amount of water is inconsequential, why can't we just use grams of actual coffee? Then we don't have to worry about how many espressos are in a 10oz mug. (Nevermind what that person's considering a standard dose for the espresso!)
Measuring extraction ratio on coffee is difficult and wildly varies based on preparation method. The standard “cup” assumes 4oz of coffee, using 5oz of brew water (so, 1oz stays in the coffee grounds as waste). I believe there’s also a standard amount of coffee grounds used as well, though.

Different brew methods extract differing amounts from the coffee, so the amount of water is indeed consequential. Same grams of coffee in to a pour-over vs espresso would result in different amounts of extracted coffee material consumed.

#48Could coffee be a proxy for a high-stress, mentally-taxing, low-sleep-quality lifestyle? How did they take their coffee? With lots of sugar?

My mom, both of my sisters and I drink it by the pot. Each of us, every day. 6 cups? That doesn't sound like enough coffee to me.
>My mom, both of my sisters and I drink it by the pot. Each of us, every day. Can I ask how's your sleep?
Sleep was fine. I used to drink it by the pot but I cut back mainly because I'd have to piss too much.

I seem to sleep as well as I always have.
I go to bed when I am tired. Usually 11pm-1am. I fall asleep in a few minutes. Then I wake up about 7am, feeling OK. Closer to 6 hours is more normal for me.
I’ve been like that since I was a teenager and I didn't drink coffee then.
