I'm 58. I've been drinking coffee daily since I was 14. For the last 20 or 30 years I've been reading articles debating the benefits or hazards of coffee, claiming it's bad for you, claiming it's good for you, claiming it's neither. You'll never hear the end of it. I will continue to have my morning coffee for the duration of my life.
I dunno man…. That might not be a good idea.
I am 40, like you was heavy drinker for 20+ years. Cut two weeks now from drinking only morning cup. Best decision ever, noticedcm coffee made me dehydrated, sleep better now, no crashes, no anxiety.. might drink a decaf coffee once in a while on Sunday but not yet. Loved smell of grinded ,fresh coffee. Try to cut it out for 2 weeks to see what did you relied on.
Were you reading "articles" or were you reading research? Science is a process by which views with nuance are gradually teased out of the evidence. You have one of the world's leading nutrition researchers telling you about the cutting edge facets to our understanding of coffee, and you boil it down to a smug "both sides" comment implying you and your common sense worked it all out 40 years ago? Do better.
Check out Jason Christoff.
I told myself the same thing a couple years ago until the day I could not even get a deep breath living hell on Earth!!!
Love it when specialists tell me that my addiction is actually healthy
Researches found that people with addictive personalities are short-term thinkers. They consider only the short term,quick reward. If health is about a long-term commitment to good lifestyle choices i dont see addictive types finding the right path or having the dedication. If your approach to life is to be addicted and look for something positive that justifies it youre probably ignorant about lots of things. A "healthy" cup of coffee will mean nothing if someone goes on to eat/drink a ton of crap.
That is because they are captured by the coffee agenda as you are. See Jason Christoff.
But how does milk affect the health benefits of coffee? Given so many people put milk in their coffee, it’s dumbfounding that this issue wasn’t covered.
Glad that I read your coment, I drink the best coffee for the las 8 years ,-3cup- Bialetti coffee moka stove and and use double the size of my coffee with hot regular milk, can not live with out. you are listnening 130 mins and not coffee with milk, WTF
Thanks for putting this video together and for all the valuable information. As a coffee roaster, I would like to offer some additional comments. Coffee is essentially the pit of a cherry meaning that coffee "beans" are actually "seeds." Once coffee has been processed, green beans can be stored for a long time (years) without losing much nutritional value. However, once coffee has been roasted, the clock begins to tick. The flavor and nutritional value begin to diminish and after a couple of 6-8 weeks the difference is very apparent. Even more critical is the grinding date. Once beans have been ground, the clock ticks even faster. After a week of being ground, coffee starts getting stale. The takeaway is to buy your beans as soon after the roast date as possible (allowing 72 hours for degassing). And do not grind the beans until you are ready to use them. Outside of the origin and quality coffee beans themselves, these two things are critical to the end result.
Valuable info!
What about freezing ground coffee?
@@bradcampbell5766 does not help. In fact it will have an adverse negative effect on the taste
So the good news is that James Hoffmann is going to live forever.
And ever and ever 👴

The most amazing lesson for me from this is that two cups of coffee has more fibre than a banana! Really interesting, as usual - thank you!
That statement is utterly false. Have you considered that filter or pour-over coffee passes through fine paper, which retains almost all solids and only allows particles that are less than couple hundred microns to escape?
Bananas not so good for smoothies either. Cuts antioxidant activity of other fruits(Amylase). I never eat them.
@@cataony813The dietary fibre in coffee is water soluble so a filter paper isn't going to make a difference. The extraction method might but not the filtration as far as I understand.
your cofee table has fiber in it as well, why don't you grind it down and drink it as well?
I've had soluble fiber drink before. They come in sachets and they dissolve like salt in water and are tasteless.
My father explained to me back in the 1980s there was magic in coffee, the vast number of his eldest patients (late 90s and a few 100 year olds) were coffee drinkers. He kept his coffee habit as well into his mid 90s. I never doubted and intentionally ignored all the doctors asking me to stop coffee over the decades.
Me too, taxi driver coffee.
well, my father's first wife never drink coffee and is now 101 years old. Almost all 90 and 100 year olds in my region of our planet never touch coffee or tea. It was not in the menu back then. They had barley coffee, but i don't think that this is the reason for their longevity.
Survivorship bias? What’s that? ;)
@@silversilk8438 well its not a study (probably n
Few years ago I decided to live healthier and one of the things I wanted to change was to consume less soft drinks. I was daily drinking stuff like coca cola at work. I vowed to completly give that up and only consume water, cofffee and tea instead. The tea didn't stick, because I didn't enjoy the taste, but the water and coffe proved to be a comfortable choice. Some people told me I was exchanging one harm with another. But I felt so much better and healthier with my choice, that I stuck with it. Awesome to hear that coffee is not as unhelathy as rumored after all (as I expected already).
I love the look on Tim’s face as James discusses the differences in coffee types. He had that “I can see another paper in this” look.
Finally, someone confirms that a pinch of salt takes coffee flavor to another level!!!
Been a German tradition, my mother always added a pinch of salt.
I put a teaspoon of salt in my coffee with butter.
I break open a green cardamom and put that in my coffee.
Can't wait for the tea study!
I'm looking forward to the Scones.

I just started the vid. I do like James’ videos. I thought I’d mention, as an Audhd-er (ADHD+Autism) I saw a video talking about dopamine.
She said,” why do “we” sometimes feel more relaxed after a nice coffee? It satisfies a dopamine shortage. The chase for that unknown anxiety satiation.
Have a link, please?
everyone just rhymes off these truisms about dopamine now as if the brain was this simple

Thank you! I grew up in Wisconsin with coffee as my warm morning beverage. I had to give up the caffeine due to heart palpitations, so had to switch to decaf, and I am so happy that it has the same health benefits. I still love coffee and have found good-tasting decafs.
Beware of the chemicals used to make decaf.
Nossa Familia, a grower of deliciously roasted Brazilian coffee, is working on a caffeine free bean!
If only coffee had no caffeine - 1 cup of coffee can make me very ill. You don’t mention such a possibility. I find your information is biased.
@@k8eekatt i should buy from them
There is. It’s called decaf. Swiss water processed is natural and 99.7 percent caffeine free
I appreciate the avoidance of the japanese tradition to acknowledge every single word from your guest. There's too many podcasters in practise, dubbing their guests with; Yeah, yeah, yes, yes, mmhm, mhm, mmm,mmm,," But nodding the head back and fwds to every word said, is really a new way to do this. LOL,, it's quite fascinating! glad there's more than 1 camera angle. Oh, yeah, and of course, great subject! Great talk! :)
loved this! James and Tim were a perfect combination as guests. Also the summaries at the end of your episodes are great 👌🏼
james hoffmann is such a cool guy. so passionate about coffee.
He needs a new jumper

THANK YOU ZOE
Thank you for this excellent, cutting edge podcast!
Really enjoyed this, thank you!
Loved this, and hope the tea podcast is also on the way.
As a coffee nerd, this is music to my ears.
I can't wait to read this study. I understand it's still being reviewed.
This podcast really opened my eyes to my health and the benefits to coffee thanks for sharing just seighed up to the zoe podcasts really interesting thanks 🎉🎉🎉
Excellent work, love the format, keep it up!
Really informative - as always. Loving all the Zoe podcasts etc.
i love this guy's voice
What a fantastic watch. Thank you!
Aup Ollie, your an inspiration i can’t wait for the day you say you’ve beat this keep us posted 👊
Refer this research article - [Rao, N.Z., Fuller, M. Acidity and Antioxidant Activity of Cold Brew Coffee. Sci Rep 8, 16030 (2018)] where they investigates the impact of hot and cold brewing processes on the polyphonic content of coffee. It analyzes factors such as antioxidant levels and acidity in both brewing methods. The study aims to provide insight into how different brewing techniques affect the nutritional and sensory properties of coffee.
In the study, the researchers observed that the hot brewing process led to higher levels of acidity, and antioxidant activity compared to cold brewing. However, cold brewing resulted in a smoother and less acidic taste profile. Overall, the observations indicated that the choice of brewing method can significantly affect the polyphonic content and sensory characteristics of coffee.
Excellent podcast. Thanks
Absolutely fantastic to have cutting edge science like this in an easy digestible format (see what I did there?...Ill get my coat). Seriously, I have a bachelors degree and masters in related subjects but been out of science for decades now. It's fascinating to see how things have moved on and to hear direct from those at the cutting edge in this way. Thank you!
I can't drink tea in the evening as I wake in the night to use the loo. Drinking coffee however I have a full nights sleep!
These things are so individual. I get nauseous if I drink tea early in the day, even after eating a meal. Other people cannot stomach coffee.
@@thehappypotter9612it's probably the tannins in the tea bothering you
Fantastic! This was amazing to me bc of the previously unknown factors of fiber and polyphenols! Who knew? Well, now I do and I'm so glad to have found this video. Thank you so very much!
7 days off caffeine feel amazing energy, clarity, back to the gym each to the own but i feel back to normal.
I am so chuffed my local pub has a coffee machine - I have the perfect excuse now
Yay!! Finally! Good news!
This is encouraging news. I have long loved coffee and currently use an AeroPress. I also have started using decaf later in the day.
Soo cool to see James Hoffman working with ZOE :D
Thank you. Excellent information. ☕
I always put Himalayan pink salt in my coffee, especially if you fast, do sauna and exercise. Losing salt needs to be replaced, so move more then have more. I also add some cayenne pepper for it's benefits to. Love the taste and benefits. Turmeric to.
James is great! I'm a home coffee roaster, so I'm obviously a big coffee fancier. His advice about water is spot on---the flavor of your coffee will depend on the water almost as much as the coffee. Good coffee is not cheap, so use good water. But you can also play with it a little; if your coffee is too acidic for your taste, you can use hard water to mellow it out. If it's flat and needs more acid, use spring water or even distilled. My well water is very hard, but my water softener removes some of the minerals and adds a bit of salt, which makes nice, tasty coffee.
Oh goodie, another home roaster. I've been doing it out of cost savings for 10 years or so. What roaster do you use. I use a metal bowl and a heat gun and metal spoon constantly stirring. Coffee for me dries my skin out. How about you, in winter especially? Cheers. Thanks for the water tips.
@@scoobtoober2975 I roast my coffee outside on a gas grill with a rotisserie attachment. Many years ago I bought a drum coffee roaster that fits on the rotisserie and holds up to 5 pounds of green beans. I usually roast about 3 to 3 1/2 pounds at a time because the motor on the rotisserie struggles with a full load. This method is great for roasting large batches, and all the smoke stays outside the house. The disadvantage, of course, is that I need reasonably good weather for roasting.
Cool, my neighbor has a similar setup, much smaller. Cheers, keep it up. just bought some new green beans.@@miketranfaglia3986
My mom has a alkaline water filter at home. That filter with my LA water is fucken perfect for coffee
Great Show
on the scientific study by Zoe, no guilt enjoying coffees ☕️
We are fortunate to have several coffee houses! Brattleboro Vermont!
I been using distill water lately with dark roasted coffee. I am 85, I feel mentally alert .I drink 3 cups in the early mornings 4:00am to 9;00: am I use African coffee it has no acidic other coffees from South America and Asian coffees has to much acidic where I use to get hardburns until I change to African coffee where they say it originated before taken to other parts of the world. I use to buy coffee from a well known coffee shop but change because I was getting hard burns from their coffee I found later their filter water was not to clean coming out from the fossette a young boy told me , plus his manager told him not to mention it to customers. Also a woman told me most coffee shops especially restaurants use water from the fossette because they don't change the filter periodically 50% of the water goes through but not too clean .
These webinars are so interesting and in presenting the latest thoughts about our health. Keep them coming. Thank you.
This is so interesting and the research so critical. Thank you Zoe from Sydney Australia!❤
I’ve been having gut issues for most of my life, Early on (5 yo), I had constipation. Up until pregnancy (34), I had a lot of the same issues. When I got pregnant, that all shifted and I was able to go everyday. After I delivered, I started having opposite issues. Never had problems with that. On and off, I’ve had the opposite of constipation. A little here and there. It is especially terrible when I am at work and I have to run up-and-down the stairs to the bathroom. So, I started eating homemade yogurt (plain) on a twice a month basis. Eating it every night with a touch of stevia and a little bit of berries OR some night time magnesium powder. I wake up and have no gas, no issues,, no problems at work. Then I heard about l.reuteri fermented dairy. I finally broke down and bought the tablets to make the fermented dairy. I finally made a batch of it and I started it last night. So far, I have no gas and I had a normal bowel movement. Sorry TMI. So I can’t wait to see your body response to this. I love kimchi. It is wonderful. I also eat fermented sauerkraut found in the dairy aisle. You could probably try that too, as it is very good for the micro biome too.
I saw that yogurt demo too. I’ve made yogurt many times in the past. I’m reluctant to use the inulin because I avoid inulin on a low FODMAP diet.
@@karentodd2678 I make it just fine without it.
James, there is a coffee shop in Las Vegas i think you should go check out. The owner has roots in Ethiopia and she has original coffee making equipment that was passed down by her grand parents, also the coffee is delicious. She roasts her own beans every week. The shop is off the strip. It’s called the Java Tree and it’s on flamingo road in a shopping plaza. If you decide to go i wanna meet you there it would fulfill a life dream of mine. God bless you James
And great panel here thanks for the talk about a lot of interesting nuance about coffee!
Thank you for a fascinating and very informative presentation.
Love James, his RUclips channel on coffee is top notch, it’s amazing he’s back on Zoe, thanks for this episode love it!!
Great and informative video. I wish that coffee's effects on things like the liver and kidneys were discussed. For some odd reason, I sleep far better if I drink coffee before I go to sleep.
I stopped drinking coffee a while back and have been wondering if I did not sleep better when I used to drink it. But oh dear, did I feel terrible when I drank coffee for two weeks when I could not get hold of decaf in my little village. I was a dedicated coffee drinker for 20 years. Then I hit the wall and went cold turkey. Very thankful for decaf I am.
Interesting program. Thank you for the information.
Great interview!
Bad sleep is due to candida or parasites. After I fixed those things I could drink a strong coffee right before bed and fall right asleep.
The speaker is very practical and honest. Some of us so much worry to be against the mainstream. To share my experience, I have been drinking black coffee a lot count 2-3 medium cup a day since few years before Covid, with the grace of God, while almost everyone affected by Covid I was among the one who has never got infected.
James talks so much faster than the others do I like his mind.
Thank you for this valuable information. I love using Aeropress. I use Lavazza Rosa coffee, diluting it with hot water, in the cup, making ut a delicious brew. I do add cream and honey, so know this depletes some of the benefits, but it's how I enjoy my coffee. I will drink it black, when out of cream.
Very informative! Thanks! I’ve been cold brewing coffee and wonder what its caffeine and polyphenal content is. I’m under the impression cold brewing produces less bitter coffee. Would love to hear your expert opinions!
Thanks. An interesting and information rich episode.
Started drinking coffee occasionally in the early 1960s when I was still in elementary school against my parents' wishes. Since 1980 I don't remember a day without coffee. I quit tobacco and hard drinking in 1983. Almost 71 now, living an active lifestyle, good vision, no maintenance meds and at 16% body fat. I can't attribute my good health to coffee but 2-3 cups a day does not seem to have made a dent in my physical condition. I've ran the gamut from instant to espresso but settled with French press as my current choice.
At 4 years old I absolutely loved my first cup of coffee and it was strong. I also occasionally need a cup of coffee to get to sleep.
I was surprised cold brew process was left out of the conversation. Does it have the same benefits?
Refer this research article - [Rao, N.Z., Fuller, M. Acidity and Antioxidant Activity of Cold Brew Coffee.

I love finely ground Turkish coffee enriched with cardamom and nutmeg It's a bit a ceremony but so worth the effort…
Cardamom and cinnamon is good too.
It is a wonderful time to live to be able to enjoy coffee at a realistic cost
So glad you get many of the same benefits from decaf, I love coffee but my body does not love caffeine
The yellow Zoe mugs on the table look excellent for those with arthritic hands - big handles!! Can one buy them>
Most useful to hear a drink I can’t do without is actually good for me!
It occurs to me that a lot of people believe that drinking coffee keeps them regular. Maybe having a consistent amount of fiber at the same time every day is contributing to that perception? Other parts of peoples diets are relatively erratic compared to coffee, which is typically drunk in the same quantities at the same time on a daily basis. I understand that caffeine has been eliminated as a cause for that phenomenon.
Coffee comment:
500 +/- years ago when coffee & tea was introduced into Europe, the attraction was bitterness.
The epicurean idea is to safely experience everything, without dying; Normally bitterness means death. (Today most want their coffee as sweet liquid candy.)
Appreciate good coffee, but not real particular. I drink mine black and enjoy the bitterness safely.👌.
Edit # 1 - Salt free!
Will study water quality.
Edit #2 - Taster's Choice in packets for on the go coffee.🎉
Very informative!
So interesting, but from a coffee loving tea enthusiast Tim please note that green and black teas can contain equal amounts of caffeine. 13:50 They can be made from leaves from the same plants. Green and white teas can even contain more caffeine than black teas. It’s complicated, varietal, terroir, growing season, processing method etc can all have an impact on the chemical composition of the leaves. 🍃
Green Tea has a lot of caffeine. I have to drink decaf GT now. GT should be brewed at 85Deg, not boiling, which reduces the caffeine a bit.
I heard that tea often contains more per gram, but we generally use more coffee per cup, so a cup of caffeinated coffee contains more than a cup of tea (generally!). Does this sound correct?
love you, guys! your optimistic vibes reinstate the values of decency, common sense, and professionalism in fundamental social behavior restoration endeavor. you give me hope that humanity as a species yet still has a chance. you are simply beautifully crafted. inside out. my coffee break today was very aromatic, sweet, and joyful, as you were alike. thank you!
*I now know more about coffee than I ever thought I would !* 🌝
What about when you drink coffee with milk or cream?, what happens? can reduce the goods properties of coffee?
this would be the only topic of concern to me as well
I would love to know that too - I had assumed that the protein in the milk would somehow neutralise the benefits of the tanins BUT James jept saying "or a flat white" made me think "really?!" I wonder what Tim's stance on added cows milk or plant "milk" containing protein is - does it lower the level of good compounds we can absorb from the coffee???
Somewhat. Much better to enjoy black coffee without all the bad stuff!
I'm 62 and have never drunk coffee! This has convinced me to start!😂
Don't do it.
me too
Consider caffeine free coffee since caffeine can really screw you up. Anxiety, heart palpitations etc.
Get caffeine free.
i have never consumed coffee either untill last year, started with decaffeinated. Get the allegedly benefits, and no caffeine. Besides, it helps me to curb hunger in dieting
My goodness. Anyone else bored to tears listening to this?
All this could be said in 5 minutes
I think I extracted more from it.
One would have lost important details and the nuances. And good coffee could be quite nuanced
I love my coffee! 😊I can’t go a day without it.
I love the gritty realism of these bros
Great coffee traditions in South India. Worth a visit
It’s really interesting. I have it going at 1.5 or 1.75 speed but then James starts talking and I must bring it back down to normal.
While listening to your podcast I made a cup of coffee in a Moka pot: when a cloud of marvelous smell started pouring out, a question ensued almost simultaneously: Is the smell alone able to produce any noticeable effect on our brain?
What about FRENCH ROAST coffees? What are their properties, compared to other types of roasts? And WHY is French roast even called French roast? 🇫🇷 Thank you! ☺️
I love a good instant coffee for making iced coffee in the summer. I so wish James Hoffman would have mentioned what brand coffee that was he made, they had removed the label. On his YT channel he did a taste test of instants and chose "Little's colombian premium instant coffee" but that was a round jar and this one is a squared round. Any idea british consumers? here in America I like the organic Mt. Hagen brand. comes in decaf too. Listening to him makes me want to up my brewed coffee game. I do start with good tasting water and use a Moccamaster machine when using my chosen freshly ground bean, but too chealp to be spending $20 plus per pound for beans. Edit: I went back and watched at slow speed and I think it is Nescafe Gold Alta Rica Blend which did not even make it past the first round.
As a coffee drinker I found this amazing and informative, especially the de-caf info. I do wish you had touched briefly on the effect "if" milk, cream and natural sweeteners are added, and the effect of these additives.
Milk neutralises the benefits, Dr Gundry discussed this somewhere
I made myself learn to love it 'Black' years ago❤
@@vanessac1965 I’m skeptical of Gundry, too many infomercials selling his “amazing” products.
Very interesting - about the fibre in coffee, I always thought that caffeine stimulated peristalsis, especially in the colon, so it's good to have caffeine early in the morning, so you can have a good movement before leaving the home, but I didn't know about the gut bacteria and fibre aspects.
I love coffee. I drink at least 2 cups everyday sometimes 4. I prefer black coffee but on occasion I’ll create some kind of latte.
Butter latte, add a small chunk of butter, whisk with small spoon/ wisk, allow a minute to settle then enjoy!
Its best morning drink ...
Happy user of Aeropress! Aiming now for 3 coffee and 3 green teas daily!
I've recently read some studies where coffee resulted in a spike in LDL Cholesterol in the range of 3-5 cups a day. Curious what the Zoe take on this would be?
Great podcast, loved this. A couple of things I would have liked to hear about though.
1. Grind size. You touched a bit on surface area but wondering what your thoughts are around this.
2. Water temperature I boil to 80 degrees but is there a temp that’s optimal for drawing out flavour.
3. Water - James brought his own water and I’ve been reading a bit about removing chlorine from water for better flavours. What’s the best method to get the perfect water for a brew
Great questions, I hope I can help:
1. There's a lot to be said about grind size, but generally you are going to vary it depending on brewing style (eg very fine for espresso, quite coarse for French press). Compounds in fine grinds will dissolve more readily when water moves through the grounds, but overly fine grinds can lead to unpleasant bitterness or congestion in the brewer.
2. generally speaking, higher temperature water will dissolve more compounds from coffee grounds. Usually, people use very hot (boiling) water for light roast coffees and pour over, and less hot water for darker roasted beans (which are more prone to bitterness)
3. If you are trying to get "perfect water" for a brew(you do not need to do this! But it is tasty), the easiest method is probably to obtain distilled water, either by buying it at a store or filtering it at home. Next, you can remineralize it using commercially available powders like 3rd wave water, which will allow you to create water with a "good" (keeping in mind that this is actually pretty subjective) mineral profile for brewing.
Hopefully this helps 😅. James has great videos on all of these topics on his channel, and if you'd enjoy a more technical, biophysical perspective, I would strongly recommend the blog Coffee Ad Astra
I make coffee kombucha from the used coffee grounds from my espresso machine. It's delicious.
Please do share how to make it 🙋♀️
Yes how do you make this. I usually put the grounds on the garden !!
Ooh, I think I would like to try that.
I love my espresso and I think that it is great that we study it. On the one hand demonizing food or drinks has always been the most annoying thing, while in life it's all about the dose.
On the other glorifying them is as annoying and unnecessary. I know that you guys know how to judge the results, but I can already see my big boned cousin declaring that he is living a healthy lifestyle because of all the coffee he is drinking.
Exercise regularly and balance your macros.
Question: what about the coffee impact on the brain-related health issues? (Dementia, Parkinsons, Alzheimer's etc?)? Is it Good? Bad? Neutral? Unknown? What roles does the caffeine in coffee play in the brain related matter? Or does the decaf coffee work equally well ?
James, Tim and Bryan Johnson need a round table
How much caffeine was in the decaf. There's definitely some. In the past some said it was half. But what are the modern processes able to get out.
I never understood the people who complained about coffee having an immediate effect on their digestion until I changed my diet. Since I started eating healthier, I get the "acceleration" effect, too. So I understand everyone who wants to keep away from coffee because it messes with their digestion. Me, I gotta have my big mug in the morning. That's 500 ml of coffee and I usually stop after that and switch to water and herbal infusions in the evening.
Oh, my! I have had cardiovascular problems and was worried that I shouldn't be drinking coffee - which I do daily.
I'm drinking coffee just enjoy my self ❤❤❤
I would have enjoyed hearing more of what the scientist had to say without so many interruptions.
