If it weren't for you I would've had first comment! Curse you Jaaaaames! Jk, love everything you do! Thank you!!!
But you didn't talk about coffee enemas. 😂
What's dayter? 😅 Data
We’ve decided we want you to be our coach, lol.
Is that My Co-Pilot or Myco Pilot? The latter sounds shroomy. 🤔
Note to all: James Hoffmann, while denying being a health professional, *did not* deny being a professional athlete
Would sign up for copilot if James is my pro coach
😅 True..
Surely that is hoff jamesmann
being the 7th Grand Slam tennis champion, you’d never know it! As they say, Humble Hames
WBC '07 Champ were talking about here!
Its nice of them to let Hames Joffmann continue his video-making hobby at the mental institute
LOL
On the other hand having James give me a coffee I.V. during a hospital stay is kind of the best case scenario IMHO. 😂
Let him talk about coffee and he will stay calm. Ask him to shut up and… no, you don’t want to go there.
@@markmillonas1896That wasn't an IV though it's an enema bag. IVs aren't open at the top so James is just putting coffee up your arse.
I almost spewed my coffee reading this comment.
Cancer epidemiologist here, this was really quite a measured video. One thing I might have considered including is that what people report consuming is rarely easy to parse from other factors such as socioeconomic status. This makes is challenging to know whether higher coffee leads to differences in disease risk or whether some other covarying factors may be accounting for that result -statistically significant, or otherwise.
Thank you. Many an impoverished person run on coffee alone, due to economic and access factors. It is nigh impossible to know how much of a role coffee consumption plays in their overall health when so many detriments exist throughout their daily lives.
word salad, understood nothing
I thought the same thing. It is expensive to have four cups of coffee in a day, especially craft coffee.
@@NightmareCrab it's not that complicated lol
@@thedylangirl I think that the point was that people of higher socioeconomic status consume coffee more than more impoverished people and so people who consume coffee are more likely to report better health due to their socioeconomic status
The effects of caffeine on anxiety, panic attacks and depression are missing, and it would be interesting if more studies would further explore this field using different roasting and brewing methods. Besides, the video is great as always!
It increase cortisol and disrupt deep sleep which result in mental issue and dependency for caffeine the next day to function.
Well from what I've noticed with myself , when in distress or pre-stress mode - don't drink coffee , for me drinking coffee is good when I'm calm , sometimes when work gets stressful i skip drinking coffee to not get more agitated .
It's a super important topic, I agree. I think all the questions should be answered at least in these two groups of slow and fast coffee metabolizers. There are also some gene single nucleotide variations (polymorphisms, SNPs) which are essential in conclusion if drinking coffee "protects" you from some serious heart disease or if more than 1 cup a day actually increases the likelihood.
Time for personalised / precision medicine, hehe :)
*Doing SNPs assay is not that expensive and everyone can get it done. Most companies who are thought by the general public to sequence your genome are just doing these assays.
I've found personally, I can have 1 cup on a good day. Black or green teas are more my speed
Agree. that’s something which is missing in this video and smth I personally most suffer from. went through lots of scientific papers on this topic just to get back to trusting my own inner feeling if I can have this yammi shot today or not :)
Imagine waking up in hospital and seeing James Hoffmann intravenously administer a cup of coffee into you.
That is an enema bag 😬💩
@@OddLeah Even better 😂
Well that would be a dream scenario 😅🤓
@@hammertime_😂
Me: “ungh….FINALLY!”
James really meticulously researched for a whole literature review and then presented it in a hospital with a coffee IV whilst wearing scrubs. Both the most ridiculous and most educational video I’ve watched in a long time.
right, and like coffee...we need MORE!!!
I can't wait to see the Hames Joffmann remix 😄
Honestly don't know how he did it. Is he actually in a hospital or are these separate videos and he's on top with green screens and some medical equipment?
And he used an enema bag as an IV.
Absolutely correct.
I remember reading a study on heart decease for office workers and they saw a positive effect for the coffee drinkers compare to the people who didn't drink coffee.
But when they re-did the study with coffee drinkers vs a group who drank an equal amount of water they saw no difference.
That is when they realized that it was the tiny amount of exercise (walking to the office cafeteria 2-3 times a day) that gave the positive effect on heart decease and not the coffee.
Is that the condition where the heart deceases? 😀
There's no way it's that easy right? Like walking to the nearest water cooler is enough to change your heart disease statistics. It seems more likely to me it's straight up from the added consumption of water, with or without beans inside.
@@GPantazis Errr besides the effect that coffee dehydrates you and is not adding water to your body
@@nichthier8d239This is a myth
@@nichthier8d239the amount of water more than makes up for it
At the start of this year I detoxed from caffeine for a month, then limited myself to one caffeinated beverage per day.
I no longer have a headache by 10am if I haven’t had a coffee, and once or twice a week I don’t have one at all. I’ve also discovered that in the last 10 years decaf has gotten pretty good (in the right cafes)
I’m enjoying coffee more than ever before, because I’ve broken my reliance on it
This is awesome. I never had an extreme reliance on it, so I’ve kind of always been in the shoes you’re in now, but the ability to go without coffee during a day is really cool. I am encouraged by your comment to challenge myself even more. I enjoy the idea of being healthy enough to naturally summon the energy that myself and billions of others typically expect caffeine to give them!
It took me so long to understand why I had terrible headaches on weekends. Then one week I avoided coffee and the headaches stopped. I really hate those withdrawal headaches. I had to switch to decaf and even diet coke in large amounts can trigger them the folowing day.
Caffeine is a migraine trigger for me so had to get off the caffeine. Got to watch even soft drinks as it’s amazing how many have caffeine. Still love coffee but it’s decaf now
I did this too when coffee in the morning gave me digestive flare-ups from my IBS. I drink coffee midday now, but being free from the caffeine dependence to wake up and not feeling the brain fog/headaches when I don't have the means to drink coffee has really changed my life for the better.
I work for a publishing house devoted to science communication... This video is a prime example of how to do *great* SciComm. I just shared it with our senior editor. Thank you, James! ❤☕
Chat gtp is going to destroy you
@@jackdeniston59 You can't even seem to get the acronym right, I'm sure your opinion isn't exactly going to warrant any reaction from them.
@@jackdeniston59I've used ChatGPT (cautiously, always double checked the output) and it's a hell of a ways off for my use in scientific research.
Even with prompt engineering I've seen grossly wrong or even nonexistent sources from the LLM.
@@calliioa Though it might be true, atm LLMs are in their baby years. Gpt4 already is as smart as the smartest of us, while not even being a toddler. It's expected that the next gen, Gpt 5, is going to have 10x higher IQ than it has now... and it's only months away. 1600 IQ AI, wondering who is going to need prompt engineering.
Well…AI is going to destroy us all actually.
I think my biggest question out of all of this is what is happening with the production of that video. That's a crazy amount of information delivered in a crazy good production setting.
Plus all the cameos deserve an Oscar 🤩
I want to know why the woman in the waiting room moved.
We don't know. But we do know that we shouldn't imply that correlation can tell us about causation.
@@Alec_Collins78Because weird coffee person…?
O think it was too create movement on a scene where James wasn't moving much and to shift the weight and focus of the shot. Both positions were very intentional imo.
"Coffee does improve another kind of performance too."
The editing, him laying down and looking at you from below, the pause, and even the tiny smirk really made me think of something else. This isn't just a video, this is a three-day Manchu-Han Imperial FEAST for Hames Joffmann, there's just so much for them to go wild with.
I can’t began to express how much I appreciate you James Hoffmann. You’ve legitimately gotten a clinic to agree to you going about filming a video on coffee. I don’t know anyone else that would put this level of effort into such a project!!
The production value of this video was amazing. Also the level of research takes this to another level. Well done, James and team, well done!
New sponsor=new production opportunities
Yeah really like the whole setting and cuts to new scenes. Keep up this production!
999: What is your emergency?
Hospital: There are 4 weird people who broke into the hospital and started filming
999: Whats the issue
Hospital: They keep shoving coffee down our patient's throat, putting coffee into IV drips, and their using the ventilators to press a cup of coffee
Hospital: The guy with the glasses is now making coffee in the bed pans
James, congratulations! As a doctor, I have rarely seen someone communicate scientific findings so clearly, concisely, and responsibly on the internet. Excellent work!
The aspect of this video that surprised me the most was that James & team found a hospital willing to let them film in their facilities. Nicely done, but I think they deserved a shout-out.
Haha thought the same, I'm thinking it might be a private clinic on a Sunday or after work hours etc.
@@anttihilja Or and Actual Set in a Rent-A-Studio.
@@miketomas8564 I highly doubt that. Have a look at 8:30 for example. It really seems like the woman sitting next to James was very uncomfortable and did not like to be filmed so she stood up and took a seat in the background. Either this was staged extremely well or it was a real hospital, meaning that they had to deal with some people in the background. I don't think was staged as James looks to the side at 8:38 when she stands up. Also, have a look at the man in the background at 5:10. Blurring his back might be an intended funny moment but it looks way too off for me. That also was most likely not intended but they had to deal with it in postproduction.
@@shiniy I'm afraid to report this is most certainly a set (source: I've worked there also), but I admire your reasoned arguments otherwise.
@@shiniy The sheer lawsuit that would be created from doing this, unauthorized, in a hospital is hilariously large. Even if they had authorization to do this in an actual hospital, there wouldn't be any random people or patients in the shots, especially patients, because that is seriously illegal. Those people that showed up were literally props for humor, they were done on purpose, especially seeing as the back at 5:10 had almost perfect timing for the cutaway.
I am from Chile, a small country in South America. I am learning English and today I learned a lot about coffee. Thank you very much for teaching me about coffee. 😊
8:37 - "The side eye while looking at phone, then move away from the crazy man talking to himself" is the maneuver all people in large cities learn to do.
I would absolutely love to know how much work went into producing this episode, with all the props and side gags. Fantastic work.
I loved the shot where sits down in the chair, and the woman near him promptly moves to another chair like "ugh who the hell is this guy?". XD
I would love a behind the scenes video because the production of this was wild!
So fun! Loved the video, and the playful shooting style. Always a bright part of my day when I get to spend a few minutes watching James.
As a physician, a neuroscientist, and a home coffee roaster, I've naturally been interested in this topic for quite a while. My review of the literature concurs exactly with what James said here---coffee is definitely not bad for you, it's probably very good for you, and it really is one of life's great joys. I think that further research may show that coffee is the one true Superfood. Drink up!
Nerd!
Now, I worked at a lab as a Research Assistant and couldn't help notice how much science relies on caffeine to be made: do you think there might be some bias when it comes to coffee research? (this is a joke question)
this dudes right bro i get faded otw to work and then chug coffee to coast . shit is awesome and definitely healthy cause i dont feel like eating which is even BETTER
Hot off the (French) press!
As a physician, I too concur.
I tell my patients that the only thing wrong with coffee, is doctoring it with cream and sugar.
The problem in my case is that an absence of coffee is bad for those around me…
it means you are addict
@@JimJakubJames even if the comment was made as a joke, I agree. If you cant go a day or two without coffee then you might have a problem.
An I say that as an avid coffee drinker
@@JimJakubJames No, I can stop any time I like, and sometimes do because I'm a control freak who is afraid of addiction - ANY addiction - but changes are noticed.
Caffeine causes behavioural changes in addicts and non-addicts alike.
@@AnotherAyushRajTBF, caffeine withdrawal symptoms are worst during the first day or two (after which they drop massively, if not "healing" completely).
You're absolutely right though.
@@JimJakubJamesyou're addict for pointing that out...
I always love your demeanor and personality during these videos. Somehow you seem logical and yet lighthearted, passionate but also relaxed, and ofc that smooth british accent is like a nice relaxing massage for my ears. Thank you for being you and providing us with such quality content ❤
James and Team, well done everyone who was involved in the making of this video, amazing work!
The level of quality videos James puts out is incredible
dealing with getting ADHD meds is extremely frustrating but good coffee and exercise has helped me focus on the business of keeping house in a similarly useful way
Preach!
For me, I've found a low dose of Concerta with some additional tea or coffee to be pretty good. But different meds wok differently for different people, and some might prefer to go without them.
Informative, quietly humorous, creatively filmed. James always delivers.
Slight precision: GERD is worsenned by coffee mainely because it relaxes the inferior esophagal sphyncter, which allows the stomac acids to go backwards in the esophagus. Great video, I love the reserch you do and the humor you bring to the subject!
And remember one thing, your tummy is made for alkaline food and recipes. This is why, when you create a recipe.. it is for that nutrient and food consumption. If you add acid on acid.. it can actually burn a hole in your tummy. (Not a joke. This is a real thing.) And your tummy's job is to break down food... so that it can be filtered, or added to the body as energy... So, before people think about whether to reduce and to process food or whatever.. We mince meat, as to help with processing. So.. I wouldn't throw away basic good ideas with the baby as well... It makes no sense. It is a weird thing that people associate as consuming minced food as food from the hospitals.. or whatever. But in reality, you do need to process some food.. but not all. Vegetables, shouldn't be over processed. Meat should be broken down.
@@MeiinUK If acidic food could burn a hole in your stomach, then you stomach acid would do it by itself. The human body maintains homeostatis, there is more danger to you erroding your teeth through acids drinks and food then doing anything to your stomach. If you add acidity to your stomach, then it will still dilute the stomach acid, since whatever "acidic" food you eat will always be higher PH than stomach acid, unless you drink straight acids, but that's rather not food.
I am an Italian American physician and just wanted to reiterate two things-coffee is amazing, and your last point that, like so many things in life, moderation is key. ☕️
Exactly!
Exactly, Even water can be harmful if you drink too much!
The lighting in the set is astounding. If it's an actual hospital and not just a studio it's even more impressive 😮
This is exactly the kind of video I've been looking for for ages. I wish more objective, balanced, and considered analysis of information videos like this were done, excellent work to all involved.
This is a really well produced video! Whole sets, great lighting and really professional editing. I dont drink coffee but I enjoy learning things!
“Awful Tabloid Rag” - Produces a copy of the Daily Mail 😂 As if it was possible, James has just gone up even further in my estimation!!
The production quality of this is top notch! Keep up the good work, love watching your videos :)
Your subtle video editing is actually the best part of your videos, and it's taken me dozens of videos to realize that, you sly bastard.
Brilliantly researched and produced episode James. Please keep weaving these into your format.
Nice touch at ~ 8:40. That's exactly what would happen if some rando in scrubs starting talking out loud about coffee studies whilst sitting in a hospital waiting room (or, really, pretty much anywhere).
Toward the end of her life, my grandma was told to drink decaf coffee for her health. She did it a while and said “I’m going to die soon anyway, I might as well enjoy my coffee”. Wise words from a wise woman. What good is living longer if you don’t enjoy it?
Cigarette smokers and coffee drinkers are the same lol.
@@steelydanfan321me who doesn't do both :
My argument to that line of reasoning has always been that it's very easy to find things just as enjoyable or only slightly less enjoyable that will enable you to be vastly healthier. Take food, for instance: for just about every item in your fridge or pantry there is a high protein, low fat and/or low carb option that is either just as tasty or 85% as tasty, to the point where it's very easy to switch to and get used to and still enjoy.
I've had some pretty nice decaf before - if I had a heart condition that made caffeine dicey, I'd definitely switch to it if it potentially meant the difference between having a heart attack or not having one and living several more years. Life is priceless, so most things you can do to extend it is worth it, and those things a rarely going to lower your quality of life to the point it's NOT worth it, despite what some moaners will always say.
@@PinataOblongata you don’t sound like someone who is 85 and been living day by day with many health issues, not knowing if you’d wake up the next day
@@classicrockonly I was more aiming my comment at the general argument applied to everyone, not someone who has already lived out their average life expectancy. That said, I still don't think I would be making poor health choices at that age, because it's probably even more important for seeing the next few years. If there are small changes you can make that are really not taking much away from your enjoyment of life, then it's always worth doing. Maybe sometimes you can still have the "full fat" version of the thing as a treat now and then, but still not all the time.
@JamesHoffmann Great video as always! Just wanted to point out that in medicine we generally talk about it taking about 4-5 half-lives for a drug to clear your system so this would mean caffeine takes closer to a full day to be eliminated. This is because with each half life, only half of the remaining drug will be cleared. So after the second half life you have cleared 75%, after 3 half lives you are at 87.5% cleared, 4 half lives gets you to about 94% and 5 gets you to 97%. The point remains, if you have a coffee at noon a lot remains in your system at bed time and you will even still have more in your system the next morning than you would expect.
That's not how a human body works. Imagine you have your daily maximum dosage of 400mg. If your body can clear 200mg of caffeine in 5 hours, it will not suddenly only clear 100mg after the first half-life is up. Half-life is only a rough guideline about how quickly certain substances are eliminated from the body when it comes to actual human consumption, it is NOT like Uranium degrading into other elements.
This video is so brilliant, i love all the attention to detail and gags, it's SO good and such appreciated effort
Brilliant content with editing to match. You never miss James!
I would definitely watch Mr Hoffmann’s content even if I wasn’t a coffee person. What a quality!
I do watch his content and I'm definitely not a coffee person!
Wonderful video James!!! I love that you explore and educate us on more areas of coffee other than brewing and product reviews!
Thank you so much James. Absolutely loved this video. In my opinion, this is the highest level of coffee related content anyone could make.
I worked in science for 20 years and I always had a bit of a dislike to many of these kind of studies. Many are done by medical students in training to become a doctor... why? Simply because it gets you into a field sooner, without a PhD you already lost almost. They want to become a doctor, not a researcher (most of the time, there are really good ones ofcourse). And that motivation isn't good for the quality of the research, you get a looooot of these meta-studies. The biggest issue is that trends are so hard to prove, bias can be all over the place and meta studies rely heavily on the other studies to have been done well. All in all, I take conclusions from these studies in and always with the biggest grain of salt added to it in my brain.
I feel that sometimes easy access to this knowledge is a burden.
Of course the word cancer also gets people to click and view ads
I love this comment. Thanks for sharing your experience.
You can see on a daily basis people claiming that 'a study shows x, y and z'.
However, if you actually look into these papers, they are rubbish written because somebody needed to advance in their academic career.
Sure thing: but the fact still remains that few substances have such positive effects in association studies as coffee.
The most logical conclusion is that probably coffee has neutral effects on health. Except perhaps regarding its effects on cholesterol, which does seem substantial from RCTs.
@@solomoncumquats776 That's usually in the title or in the proposal, because it generates funding more quickly. :) Not that I'm saying everything is always crap, but a lot is not really something to rely on at all.
@@assain2 Indeed, add to that the effect of a media outlet that only reads the summary and presto.
Another point to consider regarding cognitive/performance benefits and effects on sleep is that caffeine generally has the opposite effect on those of us with ADHD. Many of us use it for its calming & sedating effect (and self-medicate with it, particularly to aid sleep).
I genuinely spent 53 years until diagnosis thinking the world was suffering from some sort of collective delusion/suggestion/just making stuff up because I had never felt more awake, alert or experienced any "buzz" from consuming caffeine (but do love my strong coffees/espressos).
*Some people with ADHD feel this.
Dude, you deserve more subscribers and views, because this channel is full of great content and delivery!
The production values here are better than a fair few TV shows. It's great to see how enthusiastic James is. 👏
I don't think there has yet been a video more primed for a superb Hames Joffman cut than this one
Great subtle eccentric humour - fingers crossed for more in this style!
Love the research, and always enjoy your delivery.
James, I love what you've grown your work into. All because of wonderful coffee (and your wit).
I watched already expecting the answer, and I watched fully knowing I would only believe my own confirmation bias that coffee is fine for me
The only real comment needed on this thread
the production value is INSANE. fantastic informative work, James.
You too James!, I hope you have a great day! Thank you for the video!
That's one quality production, well done.
How much ever you've spent on production for this video, I'm going to say it has been worth it. Real philosophy tube contra points vibe. Good job, a truly entertaining and informative bookmark and share-worthy video.
Coffee makes me happy and therefore improves my mental health. Seems good to me 😊
wow you took the set design to another level with this one
YES 🙌🏻 As a health enthusiast and home barista, this video was super enjoyable. And you even touched on the gut microbiome! I first heard about chlorogenic acid / polyphenols and all the benefits of coffee in Dr. Li’s book ‘Eat to Beat Disease’. It definitely got me thinking, it would be interesting to see a study measuring serum cholesterol on espresso drinkers but have one group use bottom paper filters…
Appreciate the production value and just overall effort that went into all the research for this one. And glad to have confirmation that coffee is in fact good for you ☕️
My dad bless him, was drinking 9-10 instant coffees a day pretty much for something to do. Doctors couldn't understand why his blood pressure was so high and continued to stay high despite the various medications they tried. He then read something about coffee and blood pressure and cut it out almost completely... blood pressure back to normal!
My intake is nowhere your dad's amount. Only about 1 to 2 cups per day and that causes my high bp. If i dont take it at all then my bp back to normal.
the amount of research put into this video is just mind blowing and the way you explain things makes it so simple to understand.. and loved the production in this one.. always learning something new from you Mr. Hoffmann. Thanks!!!
Brilliant video and actually very entertaining yo watch! I love the balance, serious and proper information but not boring and light hearted, favourite coffee channel by a long way!!
Thorough, and succinct, as usual. Hats off to you and team.
I think an underrated discussion point is coffee's relation to stress. I often am a stressed individual and brewing and sitting down with a great cup of coffee is an incredible stress reliever.
I think reducing stress is healthy and coffee makes me happy so, I believe with my entire being, that coffee is good for you
Interesting, I've heard coffee called "anxiety in a cup"
Would you say that's specific to coffee? Probably not...
You should double blind test it with decaf and see if it's placebo connected to the experinece of sitting down. Probably vary it eith meditation or breathing exercises like boxed breathing
I heard someone say once that drinking beer is good for you for this reason. There are objectively hundreds of cheaper, more productive, better ways of reducing stress. Just saying
@@HauntedSheppardI think it's a task we get to start and complete successfully, to varying degrees of complexity and involves going through a process. How many times a day or week do you get to start and successfully complete a task?
It's good for the soul; that much is clear.
Very difficult for James to achieve at this point, but he somehow went up one more notch in my admiration when he held up that Daily Mail 👏
You keep dropping amazing content! Congrats for your channel!
Interesting note: there is a certain subset of the population, typically with ADHD (although not all people with ADHD experience this), where drinking coffee actually makes us drowsy, and feel the need for a nap. Happens with certain other stimulants as well. I always wondered why coffee had that effect on me, until I was diagnosed with ADHD. Coffee also works really well for headaches, as caffeine is a vasodilator. So, you can give your paracetamol a supercharge. Should also point out I'm not a medical expert, so don't do that unless you talk with your doctor first.
I'm also not a medical expert, though I put on some scrubs to write this comment 😁
The only reliable treatment I've found for my migraines is a cup of coffee with an analgaesic. Been my go to for over a decade and works every time!
Also works on my tension headaches but I only get those like once a year.
Thanks for that note about the impact of coffee on individuals with ADHD, certainly surprising! I imagine you'd have a similar issue with teas or is it specifically a coffee thing?
I'm very curious about this. I have some level of ADHD and often experience sleepiness after drinking coffee, but it's hard to find any good information on this. Is it really related to ADHD or is that mostly anecdotal confirmation bias?
@@ornousit's not a coffee thing, same effect with other stimulants with ADHD. (Since I take my ADHD medication (a form of amphetamine) I take a day nap 😅)
Back when I was drinking a coffee every few hours at work (before being diagnosed and medicated for ADHD with stimulants), coffee would make me almost fall asleep from a sudden onset of drowsyness. Same thing now with stimulants, though to a lesser degree. Funny how that works; you wouldnt really expect stimulants to put you to sleep haha
I have ADHD (and I'm also autistic) and coffee makes me calm and sleepy, same as my stimulant meds. It's great stuff
Can we--can we just appreciate the production that went into this video.
This video is so perfectly directed!
Awesome video! Love the depth and time spent talking about various factors. So many studies are trying to isolate single variables and you did a great job bringing a lot of those into the discussion to be considered together! Thanks!
Your videos are so well produced I don't even mind watching the sponsored part of the video
that opening bit and the hospital room set are top notch, so well done
crazy video! the research, scripting, filming, editing... bravo!!!
Informative video. I'm now decaffeinated coffee only, by order of the Doctor, so it would be interesting to know if you'll include anything as regards 'Is Coffee Good for you?' in the planned decaffeination process videos that you mentioned a few months ago. Hopefully they're still in works.
I don’t have my notes to hand, but several studies saw positive impacts from decaffeinated coffee - caffeine isn’t always the important compound offering potential health benefits
@@jameshoffmannthere are many decaf processes, perhaps a video is in order
The fiber content of coffee was a big surprise to me, I had no idea it contained so much soluble fiber. Great video all around, loved how you gave a very serious summary of complex research in such an approachable and goofy way. Keep up the great work James!
Really stepped up the production value on this one.
Really good video.
This was an incredibly detailed video and covered a lot! Awesome work :D
I would love for more research to be done into how our bodies can become dependent on coffee and the science behind caffeine withdrawal symptoms. I tried to go cold turkey on caffeine a short while ago as I'm pretty sure it was (and probably still is) effecting my sleep. I wasn't able to get over the such extreme withdrawal symptoms though, I felt like crap. It's not that I felt addicted like I had to have the coffee, I just felt like pure crap until I did.
From someone who every now and again throws scientific papers like this at you on Twitter, I'm grateful for you making this video. Even though I'm sure there are plenty of others who have done the same thing, I kind of feel a little more valid.
Thanks James :)
props to the effort put into this video my guy.
Educational and thanks for always showing the source of your information. Also appreciated your objective and unbiased commentary.
I'd love a video comparing different types of coffee for their health benefits. Blonde arabica vs. dark robusta, etc. Amazingly well put together video as always!
Glad you discuss the effect on GERD -- when you appeared on the video with Zoe discussing these issues, this was the main issue that I wished had been discussed. (My own experience is that coffee has a very mild exacerbating effect on GERD compared to some other foods, but everyone's triggers are a little different.)
Coffee is a slight trigger for mine but nothing, and I mean NOTHING, comes close to what oats do to me. If I have oats in the second half of the day, I will be choking on acid all night while trying to sleep. Coffee at least doesn't do that to me. Thank god lol.
Yeah -- for me, grain in general is a huge trigger, oats included. I used to have severe GERD and think coffee was the problem; now that I've changed my diet and the GERD is gone, I realize that it had more to do with the cute pastry I might eat with the coffee...
I drank like half a teacup full of coffee and GERD fucks me up. Nausea, acid reflux and sourness in my mouth all day.
@@80PercentScottish Wow this is crazy. I have GERD too but my body does well with oats and dies from coffee (especially hot brew and light roasts). Now I'm getting a little paranoid sipping my oat milk...
@@freechilli8755 strangely, oat milk (the processed stuff in the shops) doesn't have the same effect on me. Homemade oat milk does though.
This video is wonderful, on so many levels. Excellent work!
Thanks, great video again. Only thing I think was missing are withdrawal effects if you drink too much and the effects on the brain from overconsumption.
This felt like a Wes Anderson film
Love this style of video, good balance between mental info & physical humor. Will done presenting all the info
Love the amount of time and care you put into digging through the research super easy to digest and very usable on a totally different note I just recently opened a coffee shop and went with the eagle one that you helped design and absolutely love it. Thank you so much for the work you put into that!
This didn't surprise me, since I've read a lot of the same publications you came across in the production of this, but this was still super entertaining to watch, and was a great summary of the different areas of health affected by coffee! Great work on this one James & team!
Loved this. And shout out to the supporting cast who were giving you odd looks, ignoring you, holding inhumanly still, or avoiding you. I'm happy that it confirms my belief that coffee is at least not bad for me :)
I'd love to see a similar treatment about the current freakout over gas stoves in the US, which feels ripe for debunking. (I mean, if they're really as toxic and cancerous with benzine as some are saying, doesn't it seem like we would have noticed by now, given how widespread their use is in the population over many decades?). But that's probably a bit far afield from coffee!
Also, I loved how your ID badge says "Not a Hospital"
Great work James you are consistently compelling
This is a brilliant video. Excellent production and very well served on the information. Thanks!
A question in which I'd be very interested to have an answer to: The psychoactive side of coffee. Specifically on neurodivergent people, ADHD for example. I'd love to see a colaboration with you, where you talk to someone from the youtube space who is presenting knowledge of the fields of neurodivergence and find that out together
I second this🙌.. I've always used coffee to regulate my adhd naturally since ever. Would like to understand how it actually works
Yes, would love to see this!
I am autistic and have adhd. I have a "paradoxical" reaction to coffee (and stimulants in general).
The more coffee I drink the better I sleep, the calmer I am, and the less anxious. I have drank a gallon of coffee in a day before, on multiple occasions and I haven't had better sleep than when I did. Normally I only drink about a half gallon a day. And I drink about a half gallon of plain water too (sometimes a whole gallon depending on different factors)
Weirdly enough alcohol does to me what caffeine does to other people. If I drink alcohol I'm up all night unable to fall asleep, feeling anxious and jumpy.
@@nvdawahyaify Thanks for sharing! It's interesting because I also don't have problems sleeping! ADHD here. And I literally can feel how my brain goes from morning fog to fast connection, flood of motivation and calm happiness.
It's definitely healthy for me. Caffeine helps mitigate my ADHD symptoms and greatly improves my ability to focus. Learning that different people metabolize caffeine at different rates explains a lot for me. Every evening, around 6 pm, I have one or two 12 oz. cups of iced coffee and I'm struggling to stay awake by 9 or 10. I always thought that it was odd, given that most people I know can't touch caffeine after around 2 pm without being up all night, but now, I better understand my tolerance for it. I'd love to see these studies be more specific about cup size. As mentioned earlier, the cups I drink are rather large, but it is the recommended serving size. I wish I kew if it counted as a cup according to these studies.
I wondered if in the figures James quoted, there seemed to be a correlation between high caffeine consumption, smoking and poor diet, skewing the figures for high caffeine consumption on its own. I wondered if those who indulged in all three were those with ADHD as these are the typical dopaminergic crunches ADDers seem to reach for.
Coffee is know to have a drowsiness effect for lots of people with ADHD (many drugs have some opposite effects, in fact)
I came down to say something similar. ADHD too, and I'd been having severe sleeping problems - sometimes I would lie awake, literally unable to close my eyes. It also coincided with all the usual sleep advice of cutting down on caffeine and avoiding screens and all that, but nothing was working; If anything, I was only getting worse, because now I was incredibly bored and unable to sleep. I only seemed to switch off after I would decide it wasn't worth trying to sleep anymore and having a coffee to start a new day. Took embarrassingly long to work out that the coffee was helping me sleep, even after the ADHD diagnosis - it was giving me that stimulation that my brain was craving at that moment, which was why I was being kept so nastily awake.
@@HiyuMarten I get a bit of that. Sometimes I have coffee and it totally relaxes me. I also have a ritalin prescription that does the same. 😉
Can we appreciate the amazing sets and cinematography!
seriously fun production on this video. good work.
A little tech tip for caffeine in general, if you wait 1.5 - 2 hours after waking you can avoid the crash associated with caffeine. The reason is your brain isn't done processing adenosine until a couple hours after waking. In laymen's terms adenosine makes you sleepy and caffeine blocks cortisol but that adenosine still needs to be processed
why doesn't the cortisol continue to process even after drinking caffeine?
@@mitchellsteindler it does but that adenosine is what causes drowsiness. The caffeine is just delaying that process. Andrew huberman has a good podcast on caffeine if you want to know more in better detail.
This is something highly recommended in several scientific articles. I've been doing this for about six months now and I've noticed a big difference. Thanks for bringing this up.
I stick to this, but with the addition of only after I've eaten something
Thats pretty cool, do you happen to have a source?
* This is not cause i dont believe you, i just like reading the research
I would be very curious for a deeper dive into the effects (or lack thereof) of caffeine on people with ADHD! I know for myself, I can drink horrific amounts of coffee and feel very little to no effect on my sleep and energy levels, and I've read in a couple different places that the specific brain chemistry of people with ADHD interacts with caffeine in a unique way.
Some people even get sleepy, and coffee ends up acting like chamomile and melatonin.
I can actually take a nap after coffee. I wake up feeling amazing. I used to decide between one of the other til I realized that I felt better with the coffee + nap. ADHD as well, and I do perform better with 2 cups as opposed to one. My cups are usually 8-10 Oz. I try to keep it to two 8 Oz cups.
Im the same like you. Now make me wonder is that a good thing or a bad thing. He mentioned slow caffeine metabolic.
Yeah, I have ADHD and I can drink like 4 espresso in the evening or nothing and I've found literally 0 relationship between my ability to sleep and the coffee. I didn't do a double blind test or anything, but I did try it on different types of days and different levels of tiredness.
As soon as he said “some people can drink a double express and go right to sleep” I thought “those people have ADHD. My partner has ADHD and before he was medicated, caffeine put him to sleep. Now that he’s on meds it seems to have more of a neurotypical effect on him.
