> Studies have shown that the ideal daily dosage of coffee is about six to eight 8oz cups, ideally consumed prior to 2pm so that it doesn't disturb your sleep.
I think this claim should have been backed up with a source for the studies that are suggesting people should drink 6-8 cups of coffee each day.
Seems crazy to me! I personally don't drink coffee because I've seen lots of people develop dependency/addiction, even though I'm sure it's not too serious.
Not serious at all. Speaking as someone who has drunk coffee every day for decades, the worst that happens when you don't get your coffee fix is a persistent headache - that ends within ten minutes of drinking coffee.
Yes, me too - I had two weeks of constant headaches and both physical and mental exhaustion. I still went to work, but I got basically nothing done for the whole fortnight.
Still, I'm glad I did it - it was definitely an unhealthy addiction for me. I'm now 15 or so years mostly caffeine-free.
Same here. My digestion was worse when I was on it, as well as my overall energy levels.
It seems there is a gene that determines whether someone is a fast or slow metabolizer of caffeine. If I ever get such a test done I'll definitely check if I'm on the slow spectrum. It's associated with worse coffee outcomes.
Caffeine dependence is real, but withdrawal symptoms are usually mild. I’m having some right now. :) But 6-8 cups per day sounds crazy to me. Aside from just crazy jitters and anxiety, I’d guess there are counter-acting health risks not discussed here when drinking that much coffee. It’s advised not to exceed 400mg caffeine, and it’d be easy to accidentally drink more than twice that much with 8 cups of strong coffee.
Can this clickbait title be fixed? This is a news article covering a review. The review suggests that the (small) cognitive effects of caffeine and other things present in chocolate have mechanisms that are starting to be understood, in rodents.
Because it's a review it provides no new evidence unlike the implication in the title. Instead, it's suggesting possible neural pathways for why the cognitive effects might exist.
To be fair, this wasn't explained in detail until the Brian Herbert prequels. The movie and miniseries also left the nature of Guild Navigator travel rather ambiguous.
I've wondered if the stained mouths of the Mentats in Dune was inspired by betel nuts. They're a common chewed stimulant throughout Eastern Asia and have a tendency to stain the mouth red.
Not sure what inspired the glowing eyes of spice users though...
It is by will alone I set my mind in motion. It is by the juice of coffee that thoughts acquire speed. The teeth acquire stains. The stains become a warning.
“Findings from this study suggested that higher consumption of coffee may contribute to the lower development of brain cancer in Asian populations. Tea consumption had an inverse association for the risk of brain cancer in American populations, instead of other populations.”
That’s a pretty important footnote that might mean the causal factor here in this study is not coffee or tea, but other foods in the diet. It’s certainly a good reason to pause and question whether to dive into an 8 cups/day routine.
Sure! More than 400mg is not recommended and may lead to overdose symptoms. (Less for teenagers and pregnant women.) With strong coffee, 8 cups can easily total more than 1000mg of caffeine. Mild over consumption of caffeine causes known problems like dizziness, anxiety, and headaches. More severe overdose is things like irregular heartbeat and vomiting.
The other problem with large coffee intake is that the acidity of coffee long term can be bad for your stomach and lead to or contribute to heartburn and ulcers.
I have first hand experience with near overdose. It was after a late shift. I was at Denny's with a friend for a couple hours. The waitress would bring a cup, I'd drink it, then she'd refill it.
I got home. Feeling ... not very good at all. My friend was worried. Maybe you had too much coffee? Call poison control.
That's crazy! ... Okay, I will.
"I think I might have OD'ed on coffee, is that possible?"
Agent: How much did you drink?
Me: I don't know was at Denny's for a couple hours or so, constantly drinking refills, maybe 14 or 15 cups?
Agent: That'd do it.
I waited out the night. Body felt incredibly tired after a full day of work, but my brain absolutely would not fall asleep.
It was a horrible experience. You definitely can OD on coffee.
People who drink more coffee might eat less food. When I get any kind of craving at my desk, first thought is pull a shot. For some it might be, grab a snack.
"Coffee is very bad" sounds like a very bold claim to me and should be backed by supporting facts.
Pretty much every substance will have bad effects on your health when overdosing. But thats not to say that lower doses will produce these negative effects as well.
Food science is iffy, and different people may react differently to the same food.
Personally, I think coffee is not healthy for me. I used to drink 4+ cups a day for the last years, but stopped last year.
Since I stopped I feel much less stressed, have less problems getting up in the morning, and my sweat stinks less.
I totally agree. Coffee is also dangerous to anyone with acid reflux. everyone reacts differently and if you don’t feel right consuming something, you shouldn’t consume it, health science rules be damned.
Low-level anxiety, procrastination, jittery energy useless for humdrum work, bad overall energy levels if you consume alot of strong coffee, painful wakeup in the morning, adrenalised brain geared to snap decisions rather than measured reasoning.
Or
Bounce out of bed at 100% energy, fluid easy reasoning, easier learning, relaxed, enjoy slow movies, good overall energy, fine with humdrum activities, far less procrastination. Less impatient with people.
The caffeine-energy thing is pretty bogus. The problem for me is that I find it fun.
Just realise that giving up caffine means tapering for many people as the migrained a heavy coffee drinker can get form cold-turkey can be the worst, worse than anything I;ve ever had before. Also, even decaf and cocoa have too much caffeine, and with the reduction in tolerance as you come down in dose, so you become more sensitive. You really have to give it up completely, which is a shame. But the upside is massive.
The best way to anecdotally see if it works for you would be track consumption using a simple app (https://careclinic.io) then measuring productivity with rescuetime and seeing correlations.

Then it was all gone. Not too serious. But, the headache you're describing is just the start of withdrawing.
The literature suggests 4-14 days for withdrawal iirc. Less sure about the lower bound.
Still, I'm glad I did it - it was definitely an unhealthy addiction for me. I'm now 15 or so years mostly caffeine-free.

That's a lotta Joe.

It is by the juice of Arabica that thoughts acquire speed, the lips acquire stains, stains become a warning.
It is by Philz alone I set my mind in motion.

You say this, like 8 cups/day is a bad thing? Care to elaborate on that?

Those two links are just from super quick first Google result searches, but these downsides of caffeine & coffee are pretty well known.
Possibly unrelated tangent, but I read once that 70 cups of coffee is expected to be in the vicinity of a fatal overdose. First Google result, this article even suggests maybe ~25 cups: https://www.vice.com/en_us/article/exmwka/how-much-caffeine-...

Try having those without sugar and report back in 5 years. :)

As with most things, overdoing consumption of any substance will have negative implications.
