thirty-one participants were moderate coffee-drinkers (CD, i.e., people that usually consume between 3 to 5 cups of coffee per day).
3-5 is moderate? To me, 3 is already high.
Also, sample size is pretty low and they're all Irish.
- alexey-salmin 6mo agoI do 6-10 espresso cups per day, so 3-5 does sound very moderate.
- MagicMoonlight 6mo agoThat’s not normal. It’s like saying “I drink 6-10 beers a day so 3-5 is very moderate”
- andor 6mo agoIt depends on how much caffeine is in your cup. Rather than measuring the size of a cup, I would go by the amount of coffee, as in the weight of the beans, used to brew it. The actual amount of caffeine is not as easy to measure, and even for the same kind of beans, there is natural variation. For a traditional Italian espresso, about 7g of coffee beans are extracted. For a third-wave double espresso, it's usually 18g or more. In my opinion, 10x7g is a lot. 2x12g is more than enough for me.
- askvictor 6mo agocaffeine extraction is largely a function of time in contact with water. Espresso is quite quick brew, so has less caffeine than other brewing methods (yes, there are plenty of other factors)
- Edd314159 6mo agoThere is no realistic scenario where, no matter your extractions or bean selections, 6-10 shots of espresso a day is not an enormous amount of caffeine
- criddell 6mo agoA grande americano at Starbucks is a 16 oz drink with three shots of espresso. Have one in the morning and one in the afternoon and you are at six shots of espresso. That doesn't seem all that enormous to me.
- rpdillon 6mo ago75mg per shot = 450mg caffeine That's a bit over the recommended limit of 400mg a day the Mayo Clinic, FDA, etc. recommend. Not sure it it qualifies as 'enormous' or not.
- wang_li 6mo agoThe amount of caffeine that humans require to live is 0 mg. So ...
- IAmBroom 6mo agoIrrelevant to the question (How much is 'enormous'?).
- wang_li 6mo agoIt was a slight attempt to highlight that the conversation about a purely subjective thing is missing the point entirely. In the context of scientific discovery trying to qualify the outcome based on an individual's personal interpretation of descriptive words is a fool's errand. Attempting to justify one's personal habits or predilections is squarely in the flat earther camp of scientific belief.
- frm88 6mo agoRather than measuring the size of a cup, I would go by the amount of coffee, as in the weight of the beans, used to brew it. I feel this is more precise than the ml cup measuremnts, but if you wanted to be really precise, you'd have to specify the type of beans used (the caffeine content varies widely) and even the brewing method https://oldchicagocoffee.com/coffee-bean-caffeine-content-by-type-explained/ https://oldchicagocoffee.com/coffee-bean-caffeine-content-by.... And - there is an influence - even in the region the beans are grown. In the link I provided they even go so far as to differentiate as to genetics of the beans.
- p4bl0 6mo agoI agree. I'm deep into specialty coffee and I love making and drinking coffee a lot, but three cups is already higher than what I drink on a normal day. Also, most of the time when I go above this threshold, I drink decaf.
- benhurmarcel 6mo agoI wonder how many grams of coffee beans they consider are in 1 cup though.
- midtake 6mo agoAre the Irish unique when it comes to metabolizing coffee?
- IAmBroom 6mo agoLocal groups of people sometimes share genotype characteristics. Better studies use a broad spectrum of people - a less biased sample set. So the answer to your question is: we can't know, from this study.
- kristofferR 6mo agoThis study is Irish, so I think they likely use 170ml cups? That means a normal mug of ~500ml is 3 cups. Perhaps they even use US coffee cup size, which is 118ml? Honestly, using an unit of measurement that varies from 118ml to 250ml in a scientific paper brings the whole paper into question.
- finghin 6mo agoI’m Irish. A NORMAL mug of 500ml??? this is insanity to me
- kristofferR 6mo agoI didn't say 500ml, I said ~500ml. 500ml is quite large, but 400+ ain’t really that abnormal.
- skrebbel 6mo ago> a normal mug of ~500ml woa where is half a liter of coffee a "normal" portion?
- tomjakubowski 6mo ago500mL is a pretty typical size for a travel mug/tumblr. I'd consider that two or three servings though.
- sph 6mo ago500mL of Americano (diluted coffee) is not 500mL of espresso. I challenge you to drink half a litre of espresso in one sitting.
- hootz 6mo agoOkay, you'll definitely have to explain the NORMAL mug of HALF A LITER!
- kristofferR 6mo ago
- SecretDreams 6mo agoI drink a small cup in the morning (like 250 ml) and 1-2 Moka pot espressos (like one shot). This typically happens between 7-10am. No more coffee after that most of the time. I like to keep it in the morning routine with breakfast. Green tea and water in my afternoons. Personally, I don't feel any kind of "drug like" effects from this routine. I wonder about the strength of coffee people are drinking and the effects of drinking throughout the day rather than just the morning. Anecdotally, during grad school I drank more per serving and throughout the day, and I certainly felt quite different than my current routine. Like most things, I think people need to find some moderation/balance.
- pillefitz 6mo agoIt's less about the strength of coffee than about your metabolism. I used to be unaffected by caffeine, and now it takes a few sips in the morning to mess with my sleep in the evening - sth that started happening in my twenties I believe, possibly liver-related.
- SecretDreams 6mo agoInteresting, do you have any good links for this? I can have a coffee a bit before bed if I really want. I also used to think I had a "high metabolism", but don't say that anymore since it comes off as kind of bogus.
- pillefitz 6mo agoUnfortunately no. It's my inference, given that 23andme didn't find any genetic indicator (CYP1A2) for slow metabolism, which is in line with my experience I got more sensitive over time. So it must be some other mechanism that diminished enzyme production. Some of my liver (were those enzymes are produced) values were elevated over the last few years for no good reason, and I suspect the two could be related. It's a bit annoying, as I'm reacting to trace amounts of caffeine in coffee, tea or chocolate, but I'm more worried about all the other, possibly carcinogenic, environmental toxins my liver won't be able to filter out.
- TacticalCoder 6mo ago> 3-5 is moderate? To me, 3 is already high. I'd say 3 is still moderate and really common. 5 is getting on the high'ish side. Several of us here drink more than that.

- ziml77 6mo agoOne early in the morning, one maybe a bit before lunch, and one in the afternoon. Doesn't seem too out there. And you probably approach 5 cups if you're normalizing the size of a cup and seeing that people generally get bigger cups than that (I'd imagine one large cup in the morning and another in the afternoon would easily put you at 5 for the purposes of the study)
- jmhammond 6mo agoI drink “two cups a day.” But it’s like 24-30 ounces.
