Doctors Debunk 13 Caffeine Myths | Debunked - Věda a technologie

I think the myth for coffee being unhealthy is related to other factors and lifestyle choices. Usually if you see a friend drinking an excessive amount of coffee it's because they're overworking themselves or lacking in sleep which is harmful and we just associate that with the coffee because it's used as a crutch to maintain the unhealthy lifestyle. like everything else, moderation is the key.
People also tend to add a lot of sugar and cream to their coffee. Studies are mainly done on coffee without these things and they show benefits unless of course, it interferes with your sleep or stress.
People also tend to smoke while drinking coffee
Absolutely we associate a lifestyle with consumption of coffee
@@guieming3018 only if they're a smoker. 🤣
The unhealthy is like they basically said what you add to it. In general people want to manipulate words so if a doctor says coffee is good for you then someone wants to make a cup and put 10 table spoons of sugar in, well that just took the coffee from healthy to unhealthy on a scale. Drink wisely and prosper.
Thanks INSIDER for having us on! We clearly had a lot of fun digging into the science of caffeine!
Thanks for debunking the misinformation
Please make a podcast with Dr. Sophie! We could listen to you guys for hoursss
Loved listening to you two explaining everything in such detail. Your voices are ASMR material too, so calming and nice
You both did an incredible job!
Thank you so much, doc Ugo!! So much to learn from you guys :) ❤
Caffeine gives me anxiety. I stopped drinking coffee after a bad anxiety attack. After I stopped drinking coffee, I started having the most vivid dreams.
Yes u are defective. Just dont blame my covfefe
Same for me.
There could be many compounding factors in addition to caffeine
@@GPTblacksmith 'Could be' but not 'it is'. Drink 0 cup of coffee per day = sleep well. Drink 1 cup of coffee in the evening = won't fall asleep until 4 am. It's caffeine.
I’m a retired massage therapist and I vividly recall a client, young guy in his early 30’s that shared that he recently got a new job, he LOVED it, has a young family and is excited to provide for them, but recently was experiencing rage issues. Just would explode at the slightest thing. So while I’m working on him we start talking thru it, when suddenly coffee popped in my head, so I asked if he drank coffee or energy drinks. That was it. He was getting up much earlier than he was used to, so started the day with a couple of cups of coffee before leaving the house. Then after lunch he would buy an energy drink and slam it down because he was getting sleepy. He decided to go a few days without the coffee and happily called me to thank me for helping him figure it out. Some people are more sensitive to coffee, and that was adding to his anxiety, coupled with the pressures of a new career, and being a family man.
This was actually super fascinating. These two have an undeniable chemistry, and it's nice to see some of the health benefits coffee DOES actually provide being highlighted.
To me, she is the straight man and he is the guy who loves comedy.
@@IMeMineWho huh?
"Coffee stunts your growth" was clearly a scary story to keep kids from getting a caffeine buzz and annoying their parents.
They also said that masturbation stunts your growth. Since I'm just 5'5," I don't doubt their "scary stories."
@@l.rongardner2150 try 5"3 😭
100%
It may be indirectly responsible since sleep help children grow. Since caffeine affects sleep, it mostly stops children from sleeping correctly.
I'm not saying I agree with the myth. I'm just saying I understand where it might came from. 🤔
I've had people tell me that; I had to point out to them that I was in my twenties and had stopped growing *before* I started drinking coffee. I'm just genetically tiny.
I would love to hear these two doctors talk on other topics - clear, relaxed presentation.
:p Yeee
Well not all things are equal, it applies to different people. - Lady spitting bars, like I often do. Haha.
Every drinks are worse than coffee
Totally agree!
Perhaps they should start their own CZcams channel!
So right! Nice voices too.
I second that.
“Caffeine is not addictive but expect withdrawal symptoms after going cold turkey” 😂
Coffee is as addictive as smoking just like she said both are short acting
With substances that are considered medically addictive you might die if you go cold turkey. So yes caffeine is mildly addictive behaviourally and on a personal level but not classified as such medically that it will cause anything medically significant of you go cold turkey.
@@beconscious578 which is super misleading, and honestly makes me doubt the credibility of their other responses. Doctors command a lot of trust, so they need to be careful about that kind of thing.
@Mark Asread Excuse you. If you don't agree that's fine but you might want to explain your point of view. Hurling insults just weakens your own credibility
Expect withdrawal symptoms from changing damn near anything that's become a part of your daily routine.
The cancer thing is something I’ve actually read studies on. They applied patches of caffeine on cancer cells, and over time, it actually reduced the cancer cells. It also can help rebuild synapsis in the brain (to a degree of course). It thrills me that it can reduce the risk of stroke. I certainly love me some coffee, and only take breaks from it due to the tolerance I build up. It’s just part of my routine, and it is the only way I like to have milk in my daily diet.
They talk so calmly. I can hear them narrating all day
Ahhhh. I think you should see a doctor /s
They probably need a cup of coffee 😭
@@ocean0158 yesss 😂😂
agree! they have a really good vibe, one that only coffee can provide. well coffee and g.... LOL!!
Repent to Jesus Christ
“But he said to me, “My grace is sufficient for you, for my power is made perfect in weakness.” Therefore I will boast all the more gladly about my weaknesses, so that Christ’s power may rest on me.”

I wish they had discussed caffeine and anxiety and caffeine sensitivity. Still a great video. Very informative.
Me too! But then I realized that this video is to debunk falsities, not to reinforce what is known.
I had hoped that too! I know I have caffeine induced anxiety and therefore I am cutting it down at the moment. Also the tachycardia can in fact become dangerous. I measure my heartrate since I noticed my racing pulse and also chestpain after drinking just one cup of coffee. I have heartrates over 100 bpm after drinking coffee and when I drink like 3 cups in one day I lie in bed at night with heartrates in the 90ies. I don't have any issues when I don't drink coffee. Constantly high heart rates can eventually lead to a heart attack, so I don't know how I feel with their statement on that. Usually my pulse is in the 60ies, one cup of coffee and its above 100.
@@Sunshine27234
Exactly.
You can’t take what they’re saying as fact.
They don’t even cite studies or anything.
This is a coffee commercial in bad disguise.
@@Sunshine27234 That's why there saying in general, your statement sounds like a very personalize one. The man even stated that he has patients that he strongly advice to not drink more than 2/3 because of health reasons. Also I think anyone who would notice such increase in heart rate lowers his caffeine intake/goes to see a doctor.
@@Lock2002ful There's literally a source page in the ending card of the video
No one addressed the yellowing of the teeth due to caffein stains. Other than that, this was informative and entertaining.
Coffee staining your teeth is a myth... my mom drinks coffee everyday and her teeth are white with no stains. I've been drinking coffee since I was a teenager,I'm in my 40s now and my teeth aren't stained either. Stains come from poor dental routines-not brushing, flossing or rinsing the mouth correctly. However if you drink nothing but dark liquids all day or consume foods with heavy dye then your teeth will stain eventually but if you have good dental routine it wont.
@@rachelmm05 Or you just use a toothpaste with whitening effect....
Pretty sure caffeine is colourless. You'd be thinking of tannins, which are in a lot of things.
Caffeine is white in powder form and transparent when dissolved. You have probably couple thousand different molecules in coffee.
Yes. I have been drinking coffee ( extremely light. Just milk with a few grains of coffee powder in it) since I was 7 YO. Now I am 27 i drink coffee everyday twice with one teaspoon full of coffee powder. My teeth are also white. If you drink more coffee than the permissible limit, yes such side effects can occur
So caffeine isn't addictive and I'll be fine after a week? Maybe...but I have to get over that crushing headache after 24 hours without.
Yeah just wean yourself off and skip the headache. I used matcha and found I had no symptoms other than missing it! 😁
@@whiterock1865 What's matcha? I quit it and it was horrible, the headaches were insane and lasted around a week. That's physical dependency and addiction from what I can see, but then I'm not a doctor...
@@inspiringgrace908 macha is Japanese green tea powder. It’s about 30mg of caffeine per 1/2 teaspoonful. There are two grades, premium which is second harvest is cheaper but a little bitter vs ceremonial grade (first harvest) that is supposed to have no bitterness and a bit more caffeine. So the point is that you can make drinks with specific amounts of caffeine so you can slowly reduce your intake so you allow your body time to adjust to lower amounts keeping cold Turkey symptoms minimal.
Caffeine is definitely addictive. I've been happily addicted for 15 years....cannot function without it but I find it helps me enormously so I have zero intention of quitting.
@@whiterock1865 thanks for that, appreciate the response and the info
I think the “coffee stunts your growth” myth started as a way to get children not to drink it. My grandma would always jokingly say that to me while handing me a cup of coffee when I was young
could also be from having the coffee keep you up at night, resulting in worse sleep and sleep is very important for kids and recovery.
but i wouldnt want energetic little shits running around either
Probably more of mental growth because it will keep you up and younger children need sleep. In fact the older you get the less sleep really needed because your brain is more settled and you are less active physically.
@@xxblanksxx1 This video barely got into the effects of caffeine on sleep... the main reason why caffeine is terrible for you
@@DCSTEETSKATER123 it blocks the drowsiness and keeps you alert. wish they went more into stimulants. I do know a lot of people who have very high tolerances and can drink coffee right before they sleep though.
:3 Well not all things are equal, it applies to different people. - Lady spitting bars, like I often do. Haha.
Like many other people have said...these are the people who I would LOVE to have as my doctor. Relaxed, knowledgeable and experienced....they really give a sense of confidence to a patient.
I’ve been off caffeine for almost a year now, after a lifetime of drinking coffee daily. It was hard at first, but living without the crutch of artificial energy has made me feel more balanced and at ease with life. I feel bad for people who “can’t start their day without their coffee”. Addiction and reliance on external stimulants to do what should come naturally is just sad.
Cofees good for you though
*sips coffee* jealous?
I'm on day four haha, the first two days were horrible and I almost gave up. But I'm feeling really good now and not tired at all! Instead of coffee in the morning I just go on a short walk now and it works way better!
I get your point, but I would also put in perspective the relevance of putting the word "naturally" in something like setting an alarm at, say, 6 A.M five or six times a week to get on an activity you might dislike during eight to ten hours straight. I won't blame people who either need a morning coffee or a morning routine to be more at peace with what their daily life looks like.
@Naveen KV are you clinically diagnosed for adhd? I doubt I have it too and can't figure out if I should go to a psychiatrist
Thanks Dr. Sophie and Dr. Ugo! That was such a fun presentation, I smiled all the way through!
It'd be nice to see more from you.
Ditto!
These two have great chemistry (doctor jokes aside). I'd love to hear them educate on most anything. Bravo.
Come here to write the same :D
Yea i think she’s got a thing for him
As someone who drank 8 espressos per day while trying to juggle work and finishing my engineering degree... while sleeping less than 5h per day for 5 years... I can attest it's a bad idea! I ended up burning out and suffering from serious health issues due to not listening to my body.
May I ask what kind of health issues? Asking because I get an inadequate amount of sleep everyday and rely on caffeine and I’m 17😬
@@deenaccount8994 Sure, mostly liver issues... a drug induced hepatitis ( caused mostly by prescribed painkillers, too much coffee and on the weekend, too much booze). At 17, your body is still young, quick to regenerate and hopefully healthy but still, take good care of yourself, ok!?
@@firbolg that sounds awful😬, hope you get better tho, I will start getting good sleep soon I just got to finish these exams first🥲
@@deenaccount8994
The lack of sleep is what is bad. You need to go to bed earlier. 6hrs of uninterrupted sleep is really good. Sure, 8 is best... but make sure you give yourself at least 6.
That lack of sleep will harm you more than caffeine. More than not drinking enough water.
Like the good Drs here stated, caffeine by itself is not bad for you. Too much sugar is. The lack of sleep is. The "lifestyle" associated with pot-a-day coffee drinkers is. ( Over working, not eating healthy, not exercising, not sleeping).
I would give you the same advice I gave my own children, if you consume caffeine, make it coffee or tea. Stay away from sodas. Monster type drinks are the absolute worst thing you can consume. Too much salt and sugar. So, coffee or tea and limit your sugar to 1 tsp.
lol this is not caffeine issue. it is personal issue.
This was interesting to watch! A few months ago I saw a different CZcams video where two doctors were talking about caffeine and its negative affects on sleep. That encouraged me to try reducing my caffeine intake, because I'm a really bad sleeper (like 4 hours a night if I'm lucky). Unfortunately, my sleep is just as bad. This experiment of mine has taught me two things: 1) Don't take medical advice from CZcams videos and 2) decaf coffee prepared well is actually pretty great despite what coffee snobs say. Ultimately, I think I'll stick with the decaf as my primary coffee (with maybe some regular thrown in here and there) because I like the flexibility of being able to skip having a cup in the morning without getting the dreaded coffee headache.
I couldn't agree more with no1.
try getting some exercise
Definitely varies person to person. I have a demonstrable impact from a single cup of coffee after 3pm. Since I don't drink it regularly, it'll keep me up 2-4 hours past my usual bedtime. But based on my experience as compared to friends and family I'm pretty sure I metabolize it slower than most people.
Just wanted to say how lovely I find these two doctors! Thanks for explaining everything so well.
Slight nitpick, as far as I know something is "addictive" if there are withdrawl symptoms. It's not about severity, it's about if they exist at all. The fact that stopping your intake of caffeine leads to measurable and concrete withdrawl symptoms means it absolutely is addictive. It's just a very minor addiction that is relatively easy to ease off from. It seems somewhat harmful to say things are "addictive" only if they're "addictive enough."
ok doctor
Exactly! You are correct. But society likes to promote that certain drugs are a non issue and others are problematic. Society has drug bias for certain drugs over others when often it does not necessarily make a ton of sense. Sugar is another addicting substance.
They “say” weed is not addictive.
@@thepixie8505 That's because it isn't. No one has ever had withdrawal symptoms from not consuming it. Escapism however, is something else entirely.
Exactly. My parents get splitting headaches if they don't drink their morning/evening coffee. I don't yet, but it worries me lol
The chemistry of these two is amazing! Hope to see them together again in a video! :)
Watching colleagues talk about a thing can be so wonderfully entertaining.
Both when they get along great and when they don't... Well, at least academic colleagues.
What about our hormones? It seems like a huge topic to skip over. Caffeine disrupts our hormone and I would love to hear more about this disruption. Thanks!
Having struggled with caffeine sensitivity all my life (1/2 cup coffee per day on work days and really bad headache on weekends until I put 2+2 together; later 1/4 cup semi-sweet chocolate bits causing me to be unable to sleep for most of the night) I have to take issue with a lot of the conclusions in this discussion. My body never adjusted to caffeine. I now avoid all sources of caffeine and am quite happy. No jitters.
White tea might work well for you.
But I get you, I'm also caffeine sensitive.
You can take issue but you are not the norm and they repeatedly say that everyone metabolizes caffeine differently sooooo yeah 🤷♂️
I can take 720mg and in 3 hours be in bed and out cold
@@MicukoFelton Btw white tea (especially proper quality white tea, I don't mean cheap bag teas) contains the highest lvls of these substances because it's more concentrated in tips.
Kinda like "microgreens". So starting with red or stepping it up with oolong (blue-green) or green teas is actually slower than going all the way up to white :)
Good stuff, thanks for this video. On the subject of caffiene and sleep: I avidly read Matthew Walker's "Why We Sleep," and have followed a lot of the conversations subsequently with other sleep researchers, and this Q & A here is almost 100% consistent with those conversations. The one point that jumped out at me as not being consistent was about caffiene and sleep. I believe(?) the hypothesis that later-in-the-day caffiene consumption doesn't affect your sleep, or that it will for some and not for others, has been largely rejected. Dr. Iroku kinda touched on this during the discussion, which is that the average half-life of caffiene in your system means that if you drink it in the evening, "sleep hygiene" is negatively impacted... in *all* people. No doubt the impact is greater in some than in others, but Walker is pretty adamant from his work and his reading of others' sleep research that, even if you can 'fall asleep' after an evening espresso, the quality of sleep you are getting is measurably and consistently not as good quality, across pretty much all test subjects. Anyway, thank you for highlighting the importance of sleep, and also that coffee/caffiene is not the devil!
I was about to say the same thing! Read his book and read lots of research afterward on sleep and caffeine! That was the only thing I thought could've been talked more about in the video!
As a chemist, yes caffeine is additive by definition, it is also an easy to break addiction. Fast acting drugs tend to build tolerance and dependency fast, but are relatively easy to break. Caffeine and nicotine are at the top of that list, whereas alcohol is towards the bottom and much more dangerous to go cold turkey with.
@Fake Name It is, I've been consuming 200-600mg every single day for over a decade, but there are times where I accidentally go a week with none and barely notice if I don't have intensive mental work to do. "Regular life" isn't affected for me. It's different for everyone, you may just be unlucky.
@Fake Name it got me tired, really tired and somehow with the mood down, but I wouldn't say it was difficult. I just didn't want to have more. I can't say the same about weed, which I find difficult to quit during the first day off.
Caffeine withdraw is a real thing. Headache being #1. That being said, it is easier to quit than other chemicals. A day of feeling sluggish, a massive headache... then you're good.
Nicotine however is not an easy quit. In a study designed to test the addiction and withdraw of cocaine, they found Nicotine topped the list of chemicals that are addictive and cause withdrawal symptoms.
The quicker something enters and leaves your system the more addictive it is and the harder it can be to quit.
Nicotine was #1 for entering the system. By the time you are putting your cigarette out, the first hit of Nicotine is leaving the system. This is why you end up with smokers who consume 1 or more packs a day. The worst physical symptoms will leave after 24-36 hrs. The psychological pulls are just as strong "street drugs".
I guess it depends on the definition of what an addiction is. But I can say for sure that I experience withdrawal symptoms if I quit cold turkey. Just 2 days of being tired, headaches, being irritable, etc. then I’m fine.
It is far far easier to quit coffee than nicotine. If you ask smokers who have quit they’ll sometimes still get cravings despite having quit smoking for years.
I would've liked it if it was two scientists from different fields, e.g. 1 pharmacologist & 1 gastroenterologist, because I've found quite a few things they said to be a bit shortsighted and clearly from a perspective from their field of research only, when there's a lot of other perspectives to be included as well (e.g. effects on the brain). Especially the addiction part is quite misleading the way they described it. I trust their skills very much as gastroenterologists, but I don't believe they've offered a very accurate representation of caffeine here.
I feel the same!
A cardiologist or electrophysiologist would disagree that caffeine doesn't affect the heart.
Really? I've never known anyone that is addicted to caffeine. I've seen people that can't stop drinking coffee due to stress though. I personally could have severe headaches if I go cold turkey, but my doctor says it's a normal reaction and it's related to the veins in my brain and it's definitely not addiction.
Waste of time, a doctor knows much more about the human body than a pharmacologist.
completely agree
Hmm. Caffeine is the base of an almost half trillion industry, unlikely to get much non-biased research.
I'm a psychotherapist. A few of my clients stopped having panic attacks completely after giving up coffee.
I had to give up caffeine and cannabis to combat my anxiety, and I haven't had any anxiety since.
Yeah, I can't have much caffeine or my anxiety gets worse.
So coffee was the cause and not inherit mental health issues?? /sarcasm
Well, good for them! As has been highlighted in this video, caffeine is metabolized differently in every individual. Meaning that they were lucky to find a routine that boosts their mental health
Caffeine can also affect your balance by messing with the little hair follicles inside the ear. I've had labyrinthitis (very bad vertigo) a number of times before and have been told to stop taking energy drinks because of this, but because it happens every 5 years or so, I don't really care lol
I cut out coffee back in December and I noticed a significant difference in my menstrual cycle my cramp pain went from a 9 to a 1 pain tolerance. Now I love coffee and wouldn’t say cut it off completely, but like they said it’s best to see your doctors and really check to see if your body can tolerate it which is what I did and found after trial and error it’s too acidic for me.
I wouldn’t say it’s out of my life forever because who doesn’t love that sweet aroma of coffee in the morning, but I will have it here and there far from the days before my cycle hits.
Same here, I can't drink coffee on my period. They left out a lot of evidence imo
But it sounds like it wasn't the caffeine as much as other stuff in coffee that was the problem...? So maybe not something they would discuss in a video about the effects of CAFFEINE.
I'm really glad that you guys differentiated the difference between addiction and dependence.
There's a war on the disabled, and we're treated like addicts even in the best of situations.
What does disabled have to do with addiction?
@@treyperry9722 People who are disabled often have to take medication that can make them physically dependent on said medicine to survive.
A lot of people ignorantly believe that being dependent on medication makes disabled people addicts.
This kind of feels like a coffee commercial... I mean I know it's not "bad" per say, but I have generalized anxiety disorder and coffee definitely impacts how hard my coping with that is. There's also a sleep researcher that has pulled from tons of studies that said coffee definitely impacts sleep, and that drinking it after 2-3 PM (or 6-8 hours before bed) is a bad idea.
Even in the first part of the video we talk about adenosine being blocked by the caffeine molecule, and that it has a half life of 5-6 hours, but then drinking it won't affect sleep? We literally established that it blocks adenosine is how it makes you feel more alert, so those 2 things don't add up. I get metabolisms are different, but the mechanics behind how it works on average should impact someone's ability to sleep. I'm all on board with getting behind peer reviewed research on topics like these, I just feel like this might not be an inclusive summary and it's pretty hardcore "pro coffee".
I quit caffeine cold turkey 4 days ago, the anxiety and my constant state of tension are now disappeared, and the only downside is a perpertual headache, it should go away soon
It does, just hang in there. I had that state of tension too. It was only after quitting that I realized how much it was affecting me.
Use Vicks on ur temples. Your headache will dissipate
hell yeah so proud of you!!!! i absolute recommend decaf it helps with the headaches!
Wow thanks for sharing 👏
Hope you feel better soon 🙂
I quit coffee in January my anxiety is way less i used to drink 5 cups a day.
Having suffered from severe caffeine withdrawal several times, I disagree that it’s not addictive. It’s not as addictive as other things, but still addictive.
I find it funny that they go with “this is a myth because if you have low caffeine levels it’s not true” but MANY people have more than a low level of caffeine, my previous workplace everyone drank 10+ cups of coffee a day.
10 cups a day? I don't buy it. That's obviously over the norm which is >300mg of caffeine which is still a lot.
@@swipefn1931 oh it was over the norm, but when you’re working 12+ hour shifts with as little as 8 hours between them, 6 days a week, you start to get really worn down and need to rely on caffeine to keep awake,
@@swipefn1931 i 100% believe 10 cups of coffee per day if they work long shifts. Also depends on the work, in construction i've noticed some people be on their 5th cup before it's even 12 PM, while others like me maybe had 1 or 0.
@@luggy9256 12 hour shifts would leave 12 hours between shifts not 8 lol
@@chrish4439 no 12 hour shifts at fixed times would leave 12 hours between, when you’re on call at the hospital doing 12 hours shifts the only legal protection you have against over work is a minimum of 8 hours between shifts or you must be paid at double time for the entire shift.
So it wasn’t uncommon to work 12 hours, drive home, eat a quick meal, sleep for 4 hours and get a call telling us we had a shift and 2 hours to get there.
Caffeine is mildly addictive. I needed less caffeine as it was offsetting my Metoprolol. But I found going off from >700mg of coffee a day cold turkey to be quite debilitating and turned me into 'satan', completely antagonistic to both friends and foe. So I drew down 100mg/week instead. That worked nicely. Now I daily drink a cup of tea or half decaf, and occasional decaf as a second cup.

@@chefcorinth scientists dint know everything and science changes all the time. Look at covid
Dude if you are taking metoprolol, it means that you are not considered a completely healthy subject, of course caffeine can have bad effects on you since you have underlying issues with blood pressure.
@@chefcorinth Your "experts" are knowledgeable in anatomy and biology of humans. They aren't experts on material science or chemicals and they do not claim to be. Based on the science you claim to trust, caffeine IS addictive. The video correctly says that it is not "considered" an addictive substance. That is not to say that it is not addictive, but that it does not fall under the category for the FDA. This distinction is important and the experts did bring that our correctly, but the editors chose to gloss over that fact.
I have not had coffee, chocolate or anything containing caffeine in almost a week and my hip pain (arthritis) has drastically decreased! Remarkably different! I have not had any withdrawal symptoms, thankfully! My left leg doesn’t feel like a cement block in the shower, I don’t have to roll out of the car, I feel just shy of back to normal since not ingesting any caffeine. I have also eliminated tomatoes (nightshade veggies) within the last 3 months. I noticed a slight change but doesn’t compare to no caffeine/coffee.
Also, I can really tell a difference when I drink coffee too late in the day. I’m up much later than usual.

27 is low but 70-80 is way too high. Google says it’s around 2.1 mg caffeine per gram of espresso. A single shot is around 15g of espresso so that would be around 32mg of espresso. Some places just have really big shots.
I thought that based on what they said earlier in the video about amounts in a regular cup of coffee.
But then i suppose its because, generally, with espresso, although the coffee is strong the cups themselves are really tiny aren't they
@@ellie698 It doesn't matter that the cups are small. When you get a regular coffee at a coffee shop, what they're giving you is an espresso, with water. An espresso should have exactly as much caffiene as a regular up of coffee, and it does. Between 80-160mg or so, usually somewhere in the middle. I have no idea where they got 27mg from, but it's miles off.
64mg in a shot of espresso (1oz). 95mg in a cup of brewed coffee (8oz). It varies by region, bean, and roast, but these are the average numbers as espresso is served by the ounce across the industry and a cup is defined as 8 liquid ounces.
That whole graph would not be accepted in a academic setting. The proportions of the bars are also extremely misleading on top of the value for espresso being 100% incorrect. When comparing decaf and espresso one would think that espresso has hardly any more caffeine than a cup of decaf. Two people with their doctorates should be more aware of such a shoddy display of information.
Great doctors with such a charming way to explain these myths! I could listen to them all day. Thanks Dr Sophie & Dr Ugo!
Caffeine levels in coffee do vary some depending on the brewing method, but assuming you're doing it correctly for whatever method you use it isn't a huge difference. Getting the correct water temp is key. I use a french press, and they do use a coarse grind. But with the right technique you'll actually get better extraction from the grounds than with a drip brewer. You need to stir as you're pouring the water in to make sure there aren't any clumps that don't fully hydrate. Water should be in the 205-210 degree range, and let it sit for 4-5 minutes. Push the plunger down, and pour it into a separate container. Leaving it sit there and drinking a few cups from it over a meal will overbrew the coffee. That doesn't give you any real increase in caffeine, it just makes the coffee taste bad.
One of the biggest coffee myths is that darker, "stronger" coffee contains more caffeine. It's the other way around actually. The more you roast the bean the less caffeine it will produce when brewed. You're essentially burning off a decent amount of the bean, including the caffeine content. If you're drinking coffee in the mornings for a boost in alertness, stick to light or medium roasts. It's a win-win in my book because the darker roasts tend to be more bitter, which I'm not a fan of. You get more flavor from the lighter roasts.
Sophie Balzoras demeanor and speech just seems incredibly likeable and authentic while being professional and radiating competence at the same time. These are the kinds of people society should listen to more, instead of those shouting loudest.
The coffee talk is nice, but I wanted to hear more about energy drinks, sugar free energy drinks, etc... I know one Bang is 300mg of caffeine. Which is safe given the 400mg dose guideline, but I would like to hear more of the nuance.
Thank you for the information, I had fun watching.
You are both also very confident and it really makes you shine! Beautiful people.
Loved to watch & listen these two explaining how coffee and caffeine work! Great video with the great doctors!
The one thing that bothers me with coffee (and that was not covered here) is how it affects my kidneys. It takes from 5 to 8 hours for my body to get rid of just one cup (~300 ml), and no urine is produced during that time (for tea the time gap is 1 hour, impressive difference). So since I started drinking home brewed coffee I also forced myself to learn a habit of consuming additional water because not urinating sounds like a big bother. I only drink one cup of coffee 2-3 times a week for the delight.
That sounds smart. Did you know that coffee indeed is drying? the additional water is very healthy
Correction: caffeine isn’t an antioxidant; coffee and tea have a lot of antioxidants but caffeine is just a stimulant and adenosine antagonist
Actually, this topic is a bit skewed. Research from as far back as 2011 suggested Caffeine to be an antioxidant but it is unclear if it was finally defined as one of it it's ongoing. Might be worth looking into
They said never said caffeine was an antioxidant. They said coffee was.
Yeah and an addictive poison that attacks the nervous system( and the companies that promote these doctors to say bullshit and to be a shame of the medical community have based their billions on this addiction) too that tastes foul like all poiosns and kills the paracites in the coffee bean.
@@liosteloumpi9161 You couldn't be more wrong on literally every point you tried to make. Not being rude but you need to educate yourself before you speak with such anger.
Here's some friendly help.
1. It's not addictive.
2. It's not poisonous.
3. Does not "attack" the nervous system

5. There are many parasites of the coffee bean.
You're welcome for the free education.
@@___Zack___ I told that kills the parasites of the coffee bean that's it's natural role. All poisons are bitter coffee tastes foul you have acquired the taste as a mechanism of your body to protect itself of the poison. I'm a pharmacist and have worked in psychiatric clinic in athens let me know more about you for addictions. Read Allen carr how to stop caffeine and see for yourself the drug trap. When one speaks about coffee we think about Clooney and not about the children in emergencies fron the energy drinks. Open your mind see things as they really are
I do wanna say, although caffeine isn't "considered an addictive substance",
I do still get a migraine for a day or two when I go from 300-600mg a day to zero for a whole weekend.
I guess FDA definitions of addiction and withdrawal aren't always perfect.
I have exactly opposite experience. Anytime I drink strong coffee, my cluster headache says hello. Thank god for decaf.
This makes sense, caffeine withdrawal causes the blood vessels in your brain to relax (because the original coffeine consumption causes them to constrict) - so if you stop drinking some people get headache. But this isnt enough to make it equally addictive as say...cocaine.
@@kakefisk Of Course it's not as addictive as cocaine, and cocaine isn't as addictive as Meth, either. Different addictive substances have different levels of addictiveness, but I have seen people sleep off a meth crash vs me who agonizes over a migraine from missing my morning redbull.
Caffeine is not heavily addictive, but I think it's Stupid to say, like the doctor in this video, that it ISN'T addictive at all.
@@sifuculreif6448 when i refer to something being addictive, im specifically referring to messing with the reward systems in the brain. Once you get addicted, especially on harder drugs, other stuff stops feeling good, because the hit you get from the drugs blpw everything else out of the water.
That doesnt happen with sugar. Nobody is sitting outside the grocery store eating sugar right out of the packet. Because it does not measure up to the definition of being addictive.
Are you sure you’re not just dehydrated?
Completely de'd the caf 🤣🤣🤣 we need this type of humor in the classroom
There was a time I was sleeping 3-4 hours a day and drinking coffee all day long at school and work, otherwise I felt like I wouldn't be able to do the work I was responsible for. At the end of the 5th day I feel asleep at the office on my desk. I'm glad I have understanding superiors, they didn't say anything bad to me, they knew it was hard to study & work at the same time. I covered the those hours later.
"But ultimately, we don't want to deprive people of something that they love..." oohh I love this line. *toss a cup of coffee ☕
For me as a person with ASD and ADHD, I have found that Caffeine works well to manage my ADHD (does not take much). I used to get it through soda, now I get it through plain coffee or tea without he sugar. This allowed me to move off ADHD medication with the support of my doctor. Beyond that I don't really use it to stay awake and cut off any caffeine at 2pm
It worked in a similar way for one of my classmates in middle school. The resource department would always be sure to have a pot of coffee going for him when he needed some.
Not trying to jinx you but if you wind up homeless & unemployable you might want to revisit the meds.
It actually makes sense! Caffeine acts in the dopamine system, and so does ADHD medication. The concentration and the functioning of the molecules are different, of course, but it can help I guess!
@@lidiaghellar6947 Any stimulant will "help" to some degree. But not likely to the degree a lot of folks w ADD need.
Similar experience: I've always had a 'paradoxical stimulant response' where the first dose of any stimulant would make me incredibly sleepy.
After a short nap, good to go!
A mid-day cup of Joe leads me straight to nap-time and/or deep relaxation.
Yes caffeine is very addictive. I quit since two weeks, and I found it very hard. I can compare it with a couple of years ago, when I quit smoking. I had the same symptoms. I still have a hard time after two weeks. The first 4 days I had a migraine kind of headache, I couldn’t even open my curtains.
It ruined my life, because I drank so much that I created a zero tolerance towards cafeïne. The coffee made me literally sick.
So I decided to quit on coffee and black and green tea and chocolade. I never drink soda.
It was the best decision I’ve ever made. I feel physically a lot better, my skin looks good again and I am not tired anymore.
I do believe it is addictive, after two weeks I still have a hard time.
no more addictive than food or alcohol
Thank you for sharing and making this video. I also love the diverse representation throughout the video! Thank you!

Cheers bro
What's your favorite make of tea?
Virgin Coffee drinkers vs Chad Tea drinkers.
I love how they basically say "caffeine is not addictive enough to be considered addictive". Way to make me doubt everything they say.
I personally have a horrible time metabolizing caffeine to the point that I gave up green tea because it messed up my sleep.
They are correct. the effects of caffeine on your sleep are why everyone thinks its addictive. it will affect your REM sleep, and hence you wake up drowsy and you THINK you need it. it does not induce withdrawals or other effects that addictive substances induce.
this whole thing was presented in a way that it made me think if it was funded by big coffee...
yep it sounds about the same as doctors promoting "heart healthy" margarine or cereals in the 90s, ive had enough of medical professionals bs-ing their way thru their carreers. listen to ur own body first and foremost
Same when he said that "you can't say that tea is healthier than coffee because you can add a ton of sugar". What?
Is no one else on the comments seeing this! Very biased coverage. People want to hear doctors say it’s ok to drink a lot of coffee (
Dr. Sophie has such a smooth, soothing voice!!
I could hear her read my entire anatomy book cover to cover an I’d be sleeping like a baby, guaranteeing my 8hrs of needed sleep.
Outstanding presentation on caffeine. Back in the early 90's I decided to quit drinking soda's. I had the worst headache's for roughly four weeks; afterwards I attributed it going cold turkey on caffeine. Was I wrong?
This was wonderful to hear and listen to. I've only heard negative things about coffee. I went ten years without drinking it because people kept telling me that my health would magically improve. Honestly, nothing changed. I will now happily drink my coffee guilt-free knowing I can get some antioxidants in my diet!
But no cream(trans fat)/splash of milk ok and no sugar(use stevia, monk fruit, erythritol)
Cream doesn‘t contain trans fats.
i mean it is unhealthy
Most people’s health does improve when they cut coffee, because it can mess up your sleep even if you drink it in the morning, not to mention the dependency that you build when you drink it regularly, I swear coffee drinkers act like drug addicts before they have their morning coffee (which is not far off, caffeine is a drug…).
@@starryeyedshugoki4312 It doesn't affect my sleep though?? And I can go without drinking it in the morning. I went ten years without coffee. It's just nice to wake up and drink something warm to start the day. The video clearly stated there were positive points to drinking coffee and affects everyone differently. If people are rude before drinking their coffee then... maybe they're just rude people??
I think a better title would have been “How to justify your addiction 101”😂
They litterally just said how coffees good for you with studies to back it up. The problem is that people add sugar and creamer which is horrible for you.
We would like to thank our sponsor for this video: Nescafe 🤣
8:33. I inadvertently went off coffee cold-turkey when I bought decaf by mistake one time and I felt HORRENDOUS. Nausea, headache, cold sweats, exhaustion. Not dangerous, but profoundly unpleasant
I get caffeine withdrawals. Definitely addictive. Not a hard substance type of addiction, but addictive nonetheless.
Good video. My ex would drink 10 cups of coffee in his first 3-4 hours of waking, followed by another 10-20 cups a day. He experienced heart palpitations one morning, so a doctor switched him to decaf. I drink 150-200 MG of caffeine from tea most days, between 6 AM and 2 PM. Caffeine does affect different people differently, but reasonable amounts can be safe for most people and both coffee and tea contain some antioxidants which have health benefits.
I beg your pardon? Was your ex trying to fight the duracel bunny or something?!

I was diagnosed with Premature ventricular contractions (PVCs). My cardiologist suggested I lay off coffee and the frequency of PVCs have markedly reduced. Have been off coffee for 3 years and am feeling better.
I get headaches if I don't drink coffee so for me that's my version of an addiction. I know if I endure and go a couple of days I will be back to a new normal but the coffee's right there so I'm going to drink it. Also I've had headaches when I didn't drink enough coffee I'm trying to go to sleep. I drank some coffee and slept like a baby. Now I can tell you about my other addictions another day
Yes, a massive headache! I quit cold turkey about 14 years ago. Horrible headache for about 5 days. It is addictive. I knew that all I had to do was drink some coffee and that headache would go away. It was almost as hard as quitting smoking, which I did in 2003. It's a horrible drug that most Americans are addicted to and abuse. It's a drug that corporations love for their employees to consume. That's why it's available everywhere and so cheap. I'm surprised corporations don't give it to their employees for free. This video made me sick, I was wanting to scream at these two people! All I can say is, just try to quit caffeine and you'll find out how addicted you are to it. It'll really hit you on the 3rd day. I believe it should be highly regulated and children under 18 should not be allowed to consume it. Remember when they didn't have to list caffeine content on soda cans in the ingredients? Now they do, and that's a step in the right direction. It lets people know just how much of that awful drug they are putting into their bodies. These two people are being paid to misinform. Or they simply realized that if they come out against caffeine, their careers are over. Such lies and misinformation. Just try to quit! See what happens.
I looked it up, and caffeine is officially designated as a dependency, not an addiction. Apparently it's because withdrawal symptoms don't last too long and are relatively simple to get through, unlike other addictions. And it doesn't have the negative impact on your life that other addictions do. Which is similar to what they were saying in this video.
@@kentuckynative9452 how much coffee did you drink a day?
@@kentuckynative9452 That’s dependency not addiction. Coffee will do no harm to you even if you consume it in a long time. I started drinking coffee when I was young maybe 10 years old until now Im 32. I consume 3 cups a day on average. If I don’t drink coffee in the morning I can’t focus and my head trying to break into pieces. I’ll just drink and it will go away. But still Im a normal person, mentally and physically healthy. Coffee is not bad.
@@Yami-df2lt Needing it to function is not a good thing. From what you wrote it seems like your very dependent on it. I drank it for less time than you did ,6-7 years, but I also drank 3-4 cups a day. I know it was a problem but I thought that it wasn't a big deal because coffee and it's caffeine wasn't addictive. From when I began, the cups I needed slowly went up from once and a while to several times a day. If I didn't drink by a certain time I had this general feeling of something being wrong. Then horrible headaches would come. Which went away when I drank more. I started to drink coffee because I was afraid of the pain. I quit all together in February. I had 1 and half weeks of the worst headaches. It was like I was hit on the head and basically couldn't do anything. Unless you have a job that you can afford being subpar at for several days then you really have no choice put to keep drinking. I wouldn't say to not drink it but be aware it will easily put you in a bad loop.
It's incredible how differently coffee affects people. I have to cut myself off by early afternoon or my mind is too active at bedtime. I had an old friend who drinks a cup (not decaf) as part of her bedtime routine to relax.
I struggle to sleep and I've always done that. Since I've had caffeine there are only a few instances where it has actually affected me. I find it weird to understand how people get can a buzz from coffee, it is interesting
Great video, although I think concerning unhealthy amounts of caffeine it might have been worth an advisory that while it is difficult to get above 400mg a day on average coffee drinking habits, if you’re throwing in an energy drink that has 270mg or 300mg of caffeine as many of them do, it gets a lot easier to consume unhealthy amounts. Also pay attention to the amount of coffee in say Starbucks drinks as even their small sizes are a cup and a half, and mediums are 2 cups, so it can be easy to lose track if you’re not just brewing at home.
I do love and drink coffee but I find that tea is gentler on my anxiety disorder and will switch to tea during times of greater stress! L-theanine does wonders!
Then there are pre workout powders which some have like 250-400mg in them straight off the bat!
Fun fact, “a lot do” lies, the average is 160mg, source: I drink a lot because coffee isn’t my favorite flavor to go along with non breakfast foods
@@notsosecretsnacker5218 well it’s not advised to take more than 1 scoop (serving) but it happens, trust me, you won’t feel it like you’d expect (other than the preworkout itches)
I don't know if I would say "myth" when it can happen in excess. I've met people who drink over 2 entire pots of coffee every single day. If they watched this video, maybe they would say "see, no problem."
Edit: My nursing textbook lists caffeine intake as a risk factor for hypertension (high blood pressure).
I also know a guy who drinks arround 5 to 6 cups of coffee during worktime and another one at home.....I don't think those 700mg are that unrealistic....
@@blablup1214 No kidding
Many people now drink it in excess, especially when one “Bang” has 300mg. Plus it’s hard to make blankets statements on what is excessive. Every individual has so many factors that come into play when determining what is excessive for them. This is true for almost everything we put in our body
@@GPTblacksmith I disagree. I don't think it's hard to make blanket statements. That's what studies do. Researchers examine the effects of different amounts and then make a generalization and recommendation based on their study. That's how it works. The idea that everyone is different with their own individual factors is a misnomer in many cases.
Also i don’t think it isn’t addictive or doesn’t have bad effects. Coffee is almost relied on by people who cant get up in the morning, when i used to drink coffie i felt notably worse in the long term, which is why i stoped.
After looking at the comments, I think there needs to be a clarifying statement: Always listen to your body. It knows best if coffee is right for you, and how much, and when you can have it. Obviously these two did a great job discussing these myths, but they did say a few times to talk to your doctor. That is a VERY important statement when you're talking stuff like Fatty Liver disease, or anxiety, or people prone to panic attacks, etc etc.

Everything I knew & believed about caffeine
*Them: No, it’s a myth!*
Regarding caffeine as a diuretic, I have read that caffeine may slightly irritate the wall of the bladder and be confused with a diuretic.
Coffee is also a great source of fibre
Individual metabolism for caffeine plays a huge role. I personally get a lot of stimulation after drinking one shot of espresso. Tachycardia and inability to sleep even tho I drink it before afternoon not to mention increased bowel movement and urination. But I’m much better with brewed coffee which I just realized has more caffeine than espresso. But I dilute brewed coffee with milk. With tea, i get a very slight stimulation since in my country tea is as normal as drinking water😂. I also have GORD and Decaf might be my next choice😁
I'm on day 7 of no caffiene cold turkey and from my experience the withdrawals are the real deal.. absolutely zero energy. Falling asleep anywhere and I have to sit down after doing anything remotely active and I'm a healthy fit person. I will say though, my sleep is unreal. I sleep so good. However it seems pointless because I wake up still tired no matter how much I get lol. It's been a really eye opening experience!! I recommend anybody who is an avid consumer to take a break and give your brain/body a break from it. It's very hard, but I believe it's important to just give your body a break from altering substances of any kind once in awhile!
I feel you on the withdrawals! I know how horrible it is, but I drink 1 or 2 monsters a day with pop on a rare occasion. Once I was pregnant I stopped everything! Worst next day I'd had in a long time! Then I started a monster a day awhile after my baby was born. But hey, I'm proud of myself. That was the longest I've ever gone without caffeine.
It takes about 2 or 3 weeks to get your true energy back, but if you can go the distance you'll start waking up full of energy that lasts all day!
How adorable they both are. Makes me wanna get my stomach checked at their clinic 🤣
I'm very sensitive to caffeine and have to be careful of my intake or I cannot sleep for several days. I usually try to not consume any after Noon due to this issue. Coffee is a no go and most teas are out as well.
they speak like radio hosts and i mean this as a compliment
it is easy to listen and focus on what they're saying, and absorb the information they're providing
Ah, two smart educated individuals covering coffee myths. This made my day… glory to the cup of Joe!
Caffeine addiction is usually behavioral compensation for not getting enough sleep. Lack of sleep causes the action (drinking coffee). The result of that is not feeling tired (for a couple of hours). You notice this -- perhaps unconsciously. So, when you feel tired again in a couple of hours, you drink more coffee. Do this several times and it becomes routine (habitual).
This addictive part of this cycle is that caffeine degrades the amount and quality of your sleep. This causes a positive feedback loop of: tired due to lack of sleep->caffeine->causes more lack of sleep/lack of good quality sleep->even more tiredness->drink even more coffee.
Some people might say so what? Three things --
1) you need to bring caffeine with you or have a source, which isn't hard, but if you suddenly find yourself in such a situation, your mental performance will be very bad at least until a couple of days pass and you finally get healthy, normal sleep in addition to the minor withdrawal effects wearing off.
2) Only natural deep, REM sleep "scrubs" the brain. Without going into details (of which there are a lot), sleep is maintenance mode for the body but particularly the brain. Not getting deep sleep for many years will shave years off your life. I believe that it's 1 hour per day = 6 years less of life. So if you should be getting 8 hours but only get 6, you'll live 12 years less on average than if you had gotten your required eight assuming that you did this your entire adult life. Your healthy elder years when you're still physically and mentally fit adjusts accordingly.
3) Caffeine addiction is linked to a lack of creativity and lack of the ability to recall recent past events. This is connected to lack of quality deep sleep as well. Dreaming is your brain in "sandbox mode." You take various things that happened during the day and "play" with them using older memories. That's why dreams are sometimes weird. But even if you don't remember your dreams, it's still forming those connections. Such "weird" connections enhance creativity because you have outside the box "memories." Your waking, rational mind can use such connections in novel ways to form useful ideas. For this is even happen, you have to form such memories in the first place. Tiredness greatly affects short-term memory. Even though caffeine makes you feel not tired, there's still something else going on here that impedes the formation of short and medium term memories. It's almost certainly related to the "scrubbing" of the brain that happens during deep sleep. This is why someone who pulls an "all-nighter" using copious amounts of caffeine will almost certainly forget most of what they learned and even basic events like "did I eat lunch?" This effect happens before the person sleeps and persists after the person sleeps. It basically makes a memory black hole.
tldr -- caffeine as a chemical is fine considering normal dosage. However, it can cause a positive feedback loop involving lack of sleep and increased caffeine consumption. Caffeine is a poor substitute for normal, healthy sleep and it results in long-term physical effects and short to medium term psychological effects; therefore, responsible consumption of caffeine means not using it as a crutch for not getting enough sleep.
Thank you for this video. I tend to drink ice tea in the morning with breakfast, and will brew a pot of coffee during morning break at work. I have friends who think I'm consuming too much caffeine.
My adenosine: "Sleep."
Caffeine: "No."
My adenosine: "SLEEP!"
Caffeine: "Okay."
One that I would have liked to get answered: does the additional alertness you get from caffeine wear off if you drink a lot? Can you end up in a spiral where you need more and more caffeine for the same benefits?
That's something I hear often and I'd love to get an answer by experts
From my own fighting against caffeine, I would say yes. You can absolutely reach a spiral where you need more to get the same.
I would at the beginning feel very alert from 2 cans of energy drinks which over time became 4 and went to 6. Once I had hit the need to have 6 cans of energy drink to feel the alertness, I could basically go to bed after downing 2 cans less than 10 minutes earlier. No sleep issues at all.
I am however not an expert.
Yes, happens. At more then 700mg of caffeine a day, I needed that much to approach feeling normal. This is why I totally disagree with these two doctors saying that caffeine isn't addictive. It's a mild addiction. But, just like alcohol, if used in excess, it starts having diminishing returns. For best ongoing effect, the caffeine needs to be completely out of your system for hours every day. It takes about 10 hours to clear the system. I try to have most of it out of my system be bedtime. I am now between 25mgs and 75mgs caffeine a day, this is a slight boost, which feels nice. And if I skip a day I feel a bit laid back, without the headaches. It took a weeks to draw down to this level.
This is an excellent and professional presentation! You did mention that there can be occasional incidents of inappropriate responses to caffeine. Here's a couple:
An older friend, a plumber, was having issues with throat arthritis. (Yes, there's a bone in there, the hyoid bone!) Tissue and blood heavy metals including lead were quite normal, so doctors were stumped. Near the end of one of our conversations, he said that he should go home and make another pot (not cup) of coffee. I asked; thus far that day he had drunk only two of the four pots he consumes every day. A reduction of his coffee intake under his doctor's supervision eased the discomfort in the throat. (Of course, it may not have been the caffeine or just the caffeine alone; a food sensitivity to coffee or reactions to other ingredients such as sugar may have played a role.)
2nd story: my petite female friend came to my place of work to get a ride home. She looked a little pale; I asked, and she said she felt light-headed. I asked if she had done anything or eaten anything unusual; she said that she had consumed four cups of coffee, but normally would consume just one. I took her pulse, and told her I was going to take her to hospital. At first she refused, but I managed to get her there. I told the triage nurse that my friend has a pulse rate of 180, the nurse very matter-of-factly said I should let her take the vitals. She then took her pulse, then quietly excused herself, and 30 seconds later the nurse and a full team placed my suddenly frightened friend on a gurney and carted her into an ER book, plugged in an IV, and gave her a bolus of whatever that drug is that has a half-life of 11 seconds and when it reaches the heart, suddenly and dramatically drops the pulse. In her case it dropped to 80, and aside from the mid-arm IV puncture, was feeling better.
I did note just one minor professional faux pas: "When I drink coffee at night, nothing happens." Although the rest of the presentation is quite objective, even though it makes a personal connection, a first-person anecdotal example dilutes the appreciation of the significant information; it would be better to rephrase it in third person to give at least some illusion of objectivity! 😊
In the times I used caffeine, I had an hard time starting my day before I had my first coffee and whilst I had an energy boost after that, I crushed again 3-4 hours later just to have another one. When I switched to decaf and waited for one or two weeks to get out of the withdrawal, I noticed my energy levels were much more stable. Yes, I didn't wake up singing like a disney princess, I still had a little fatigue in the morning but it lasted way less before I could start my day without the coffee and I could function well without the downs until I was naturally tired and went to sleep at night.
I don't ignore caffeine has some benefits but I think these two doctors totally ignored its contribution to anxiety, sleep disorders and general tiredness. Also, if you need a substance to "start the day" it is addictive, it doesn't matter if that addiction is severe or not. I couldn't help but feel like this video was sponsored by some coffee companies.
I switched to decaf cause I love the smell, taste and the ritual of having a coffee but I wanted to get rid of its effects such as being jittery, sleepless and anxious. I know decaf also contains caffeine but it is so little that it may count negligible if you don't drink more than 4-5 cups of it a day.
Having cert doctors debunking tons of myths for a substance that has been on the crosshairs of health science for years.

I decided to go for decaf and felt just like you said. Its way more natural for your body to have your energy being used in a more stable way than spikes that makes you enter a vicious cycle.
Ok doctor
They just answered wether it's a myth or not bruh
I like how They talk - very gently and friendly👍
Great presentation. Clear and easy to understand without being at all condescending. Good work, docs.
I know a lot of people who are addicted to the sugar in the coffee more than the actual coffee.
I am guilty of this
I used to put sugar in my coffee when I was younger. Now I'm on low carb and drink plain black coffee, never felt better in my life.
@@Metzger23 I also only drink plain black coffee, but it's not wrong to say that many people are addicted to the sugar in it, although they might not only get their sugar intake from coffee, but from soda, candy, pre-made food which is actually savory, but filled with sugars (ketchup, salad dressings, most potato chip items, premade dishes, etc)
6:51 that’s why I love European coffee culture so much.
In many places especially in Austria and Italy you often get a small glas of water with your coffee, especially with espressos. So you don’t have that feeling of thirst afterwards and your teeth get a little rinse.
Loved these two, however... One thing I think they overlooked is that caffeine comes from more than just coffee, and a combined amount depending on how much people eat + drink could drive a daily excess of 700mg, especially energy drinks which are very popular. Until a couple months ago, I regularly drank at least 2-4 Monsters a day, sometimes more, and Monsters typically have around 150mg of caffeine per can. This isn't including the fact that I also drank various soft drinks as well. I've since cut back on the energy drinks a bit, generally limiting myself to no more than 3-4 a day... but it really isn't as hard as he makes it out to be to hit over 700mg of caffeine in a day.
How are you cutting it back by going from 2-4 to 3-4
Energy drinks spike your energy more with the horrendous sugar content than with the caffeine. Even sweeteners in so-called sugar-free energy drinks have a dangerous effect on your GI track and hormones. Pre-workouts also easily push that 700mg threshold, so I agree with you on the sources of caffeine.
@@lx4079 if you read the preface of it, I said "regularly drank *at least* 2-4", as in that was the bare minimum, often more like 4-6. while now my *maximum* is 3-4 for a whole day, trying to stick to 2-3 when i can.
How are you not full on that much carbonated drinks??
Bruh drinking 4 cans of monster a day is just insanity and I wouldn't consider it"easy to do " both for health reasons and ecomomic ones.
Not because of caffeine but because energy drinks come with sugar/artificial sweeteners that will ruin your mouth, liver and kidneys
I myself drink a lot of coffee because even if it's processed, if you only drink it with milk and no sugar, it's almost a natural product.
Considering the size of coffee cups out there, like getting a "Venti" or whatever, getting that 700+mg per day is probably a lot more common than they are acknowledging. Also, a standard bottle of pop has about 100mg of caffeine. Pretty sure kids drinking 1 or 2 bottles worth of pop is not unusual.
My wife and in-laws like to drink coffee right before bed. The caffeine doesn't affect them very much but the nice, warm drink helps to relax them for bed
Same, coffee just before bed.
I believe caffeine is addictive, because when I used to drink it I did ALOT and when I didn't have any I would get a massive headache.(AKA withdrawal symptoms)
The body adjusts to what you consume. You'd have the same headaches if you had a daily habit of taking aspirin, as both caffeine and aspirin are anti-inflammatory.
It just doesn't reach the level that's addictive. Other things greatly change and alter the body making quitting hard. Nicotine for example doesn't just alter the mood but also alters the entire system that clears out mucus
They didn't answer the most important question! Caffeine makes you poop 💩!
Doesn’t work for me that way
Eating makes you poop.
I bet on pee since caffeine have an diuretic effect.
It does the same thing to the adenosine receptors in your gut as your brain and increases gut motility. If that's what you're asking lol. Kind of the same as when you exercise, you need to poo.
I don't think it's caffeine I think it's something specifically in coffee, because energy drinks don't make you poop, and decaf still can. I don't remember the actual chemical, but I believe it stimulates the gut to move and adds more water to the gut as well.
It doesn't do that to me, but it does do it to my son. We both have adhd but different types. I got him to try it because they say it calms the crazy but it just had him running to the toilet even more than usual!
Great info. This is touched on around 9 minutes in, but it's really important to know how many mg are in prepared / canned drinks. There are some 12 oz cans of cold brew for example that contain over 300mg, and many people are unfortunately thinking of it as "only 1-1.5 cups" because of volume.
Yup. And 400 mg is recommended maximum. But if you brew your own it's way less. Modern espresso will have up to 40 mg per double shot, filter about 70 mg / 100 ml, so maybe 150 mg for a big cup. I have 1 filter and 5 espresso a day giving me about 400 mg a day the recommended maximum. A can of Monster Energy is 400 mg lol. That will rack up your dose fast
Thanks so much for this, I learned a lot. One thing I'd love to know, as a green tea drinker... I steep it for a loooong time, and then squish as much from the leaves as possible... is there any known down side to this, other than my dental cleaning bills?
I’d love to know about bean differences too - it sounds snooty but I get headaches every single time from Folgers but I have Starbucks pike blend and zero negative signs. Also so donut shop coffee overloads me and makes me feel horrible - while others like SB make me have a nice clean jitter. It’s super weird and now I’m a snob with what beans I have.
“Not addictive but you’ll feel like crap if you quit” lol
That's true, I quit drinking coffee back in August 2020 and it feels like crap. A warm cup of coffee always made me more moody yet I decided to quit because of my stress issues which eventually lead to me suffering from hemorrhoids. I ended up in a surgery where I was cauterized inside and outside and my gastrointestinal and digestive systems were messed up for approximately 6 months. I am not a fan of decaff or alcohol free yet I've had decaff before. I feel that if I am to drink coffee again, it won't be decaff; I'd rather learn to balance my caffeine intake than being dependent on a product where I'm uncertain whether the whole process of removing the caffeine is healthy or not.
Yes you are right, caffeine withdrawals are some of the worst. I think that if something gives such effects on the brain if you stop, then surely it's doing a lot to the brain when you use it.
