@@wumountaintea love all your videos, they are presented with such great details, I find them very interesting and helpful! Other people just claim tea is beneficial for health and weight loss but doesn’t explain why and how .
I've often noticed that with certain green teas, after a good session, I start getting a bit dizzy and hungry and have to eat a candybar or something right after. I did some cursory googling and some people were saying Green tea always drops the blood sugar level. Nice to have confirmation that those people weren't just saying random things!
Yep Green Tea on an empty stomach can definitely be over-stimulating at times... I usually start my day off with something a little more oxidized - White Tea typically - or at most a Raw Puer (which can still be too intense depending on the Raw Puer). Glad you liked the video and were able to apply it to your experience 😊🍵🙏
I'd grab a piece of fruit instead of a candybar. You still get the sugar replacement PLUS fiber, vitamins, minerals, and plant proteins without artificial additives and refined sugars.
I’m a retired physician who hasn’t spent nearly enough time and attention to tea. Your series has really awakened an interest in me. As an avid collector of wine and with a bachelors degree in chemistry under my belt, I have traveled down this road many times learning about there chemistry and health effects of wine. Perhaps I have never been exposed to high quality tea. Your videos make me eager to begin a new exploration. It’s never too late, I suppose.
If you ever in SF, go to Chinatown and find the Imperial Tea Palace on Broadway. They also had tasting rooms at the waterfront building and another one in Berkeley. Ask the owner to intro you to kungfu (art of) tea tasting. Fong is a native of Hong Kong and very few people in the US know as much as him when it comes to tea. I spend years in looking at tea rooms all over the world including China and Hong Kong (not Taiwan, unfortunately) and Fong’s is the best. Also take a look at their website (google it).
I read somewhere that adding milk to tea as is the custom in the UK causes some of the active ingredients to become inert because they bind to the milk. I believe this has been demonstrated by an epidemiological comparison in the benefits of tea drinking between the UK and Holland because the Dutch don't add milk and appear to get more of the purported benefits. Some of the very best teas can cost hundreds, so hold the milk if you go down that route is what I'm saying...
I've been loving this series. There's plenty of tea content creators out there who I love, but they typically only bring product hype or high-level education. You're filling a void (at least in the UA-cam world) of easy to digest information about tea and the science behind it. When I watch your videos, while sipping tea of course, I'm always more grateful for the tea I'm drinking and have collected. Thanks for deepening my relationship with tea as well as expanding my knowledge of my practice/hobby. 🙏
Tony thank you so much for this comment!!!

So cool 😊👌🍵🌱 Thanks again for watching and commenting - plenty more videos on the way 🙏 - Dylan
One thing I remained unclear about was just how much of this was particular to green tea and what was applicable to all tea types. I wish you had addressed that clearly at the start. While I assumed that at least most of it was generally applicable to all, as the basic chemistry of tea remains much the same, even if the proportions don't, there still remains some differences between types. And I don't know anywhere near enough to recognize when it might make a difference. I'm just getting into the subject really...
Had a brain fog over me for the last few years, all I drank was water, within 2 weeks of resuming drinking green tea I feel alive, it's not the caffeine as its decaf green tea, l theanine is great, my blood pressure is back to normal, Im cracking jokes like the old me, I'm also a lot more calm now and rational, great stuff
Your passion to educate the world about tea is extraordinary. Thank you for sharing these in-depth aspects of tea. I began my love affair with tea around 25 years ago. Now I have around 70 different teas in my collection. I was blessed to actually visit Darjeeling back in 2017. So beautiful. So yummy. I have visit to Yunnan on my bucket list. Also Taiwan. So much tea, so little time. Thanks again
This series is amazing, great job putting this together. I binge watched the first 5 chapters in one night! Thank you for your hard work presenting this info.
This is the first video I'm watching on tea. I am a very casual drinker and don't know much besides that I like green tea with honey and lemon. But I know there's so much history and culture behind it, and I know I'm just scratching the surface with this one video. Ill be watching the rest of your series and taking notes, very interesting work. Thanks for sharing
I never thought I would get interested in the health aspects of tea. I knew tea was positive for my health but I had no clue it was to this degree. Maybe because I never bothered to read long articles about its health benefits, I would rather read articles about its history or various brewing techniques. But this video... this has actually made me interested in the health aspect as well!! As usual, thanks for providing us with great content!!
Anas, That's great to hear! 😃🌱 It's fascinating how tea can entice people for so many different reasons. My goal in creating the Masterclass was to provide 8 unique lenses through which people can understand and appreciate tea. At the outset, people tend to have their favorite sub-topics, but, like you, tea lovers are often surprised to learn that new aspects of tea intrigue them as well. Personally, Tea and Health might be my favorite sub-topic of tea (perhaps a tie with sustainable tea field management). But, in creating the Masterclass I also realized that Tea History is far more interesting than I had previously thought. In tea, we have a lifetime of discovery and appreciation at our fingertips. Thanks as always for watching and commenting, and I look forward to hearing from you in future videos 😊🌱🍵 Best, Dylan
Super high quality summary, especially the digestive enzyme enhibition kind of blew my mind! Super cool to find such a sound breakdown of the recent science about this, esp as a pharma sci myself it's frustrating how most info about this is surface level in one of the 2 extremes you mentioned (due to which I was honestly sceptical biased towards the 'no effect' group). I don't think I've ever heard of the bioactive EGCG metabolites forming due to gut microbiome. Admittedly I never felt like diving into pubmed for this info myself lol. Good to see that there's decent indications that the daily 煎茶 is doing some good.
Nice comment 👌 Right, surface level on one of the two extremes (the lazy perspectives). The microbiome-mediated alterations of the tea polyphenols is a hot research area right now. It appears to be really important but wildly unpredictable/variable. Will be reporting more on it as more research comes out! 🌱🍵 -Dylan
This masterclass as a whole is a gem 💎, you dive deep into the subjects while still being clear and an outstanding teacher. Glad I found your channel ;)
I had no idea there were so many health effects of tea. How wonderful! Thanks for sharing this information. I'd love to hear more about the impact of tea on cancer prevention, treatment, and skin health. Also, it would be great to have links or a list of citations for the video. Did you say that was in the PDF? Thanks again!
Hey E, Sure, I am working on a tea and skin health video now, and the cancer topic will be covered too at some point. As for a complete bibliography, the best I have are the on-screen citations in the form of the article title and author shown on the screen as I discussed the findings. If I missed an on-screen citation and you would like to check on the source of the thing I am saying then just let me know and I can send you the article that I referenced for whatever I was talking about. I made sure that everything said in this video was supported by peer-reviewed research, so there are definitely research articles relating to everything in the video. Just let me know :) Thanks for watching and commenting! Hope you're enjoying the Masterclass 😊🌱🍵🙏 Dylan
Another insightful video - science is everything! I knew that tea was good for helping out with thise glucose spikes but actually learning the mechanism behind it was minsblowing! It will be very interesting to have a video on tea compounds' effects on skin and a big one for me is female reproductive organs.
Ok I like to refer to that glucose spike inhibition here.I did notice since having few cups of oolong every day,I don't have energy crashes after especially white rice heavy meals,so feeling actually more tired and yawning after this meals,which is somehow normal response of your body directing all resources to digestion.super intresting
Your tea videos are awesome. I never thought I would become enthusiastic about tea, but who knew? I’m ready to shop for some first flush tea. You have presented a lot of information which I am enjoying through your excellent videos. Thank you.
I love this series! I would love to watch a video where you talk about which teas are good for skin/ hair health. Teas that help clean the lungs and heal
Nice~! I've been so excited for this, I refreshed my UA-cam like 5 times today >.> There's SO MUCH misinformation about this where I live, so this is amazing content and I will be forwarding this to a bunch of people.
Great!! Thanks for watching bro 😊🍵 Yeah plenty of disinformation on this topic where I live too... so I hope this video can help nudge people in the right direction. It's really a complex topic and new things are being discovered all the time... but a main goal of this chapter was just to demonstrate how I personally approach the topic of tea and health - which is with a relatively open mind but still centered around scientific experimental findings. Cheers brotha!
I can attest that having suffered with food sensitivities for a long while, as soon as I took on tea drinking, most of my digestive issues went! Coincidence...?
That's great!! I recently finally got my own brother to replace his coffee habit with tea (we're starting with Ripe Puer), and he saw his heartburn issues reduce almost immediately. These stories (and the research to back them up) are my biggest motivators to keep spreading the word on tea. Thanks for the comment Gabriel! 🌱🍵🙏
Can you explore more of the benefits of drinking tea and the effects it has on reversing the damage of brain cells and neurodegenerative disorders. Basically how tea can help create a healthy brain biome. If that's a thing. Thanks for your videos they are really informative and entertaining! Namaste!
Wow, I am so glad to have found your masterclass! This is just mind-blowing ❤ A big hearty thank you for making this knowledge available to us, Dylan. You are an outstanding teacher! I have found a treasure today that I can share with my community here for deeper wisdom ❤❤ From India
Another awesome video. Thank you for doing these......interesting too....think about all these young people I hear about with depression....yet they eat out almost every day...and any tea they might drink is bottled garbage. Gut microbiome is so important.
Thanks!! Glad you liked it 😊🍵 The gut microbiome is SO important - if people take one thing away from this video I hope it's just that we have to be looking after our GM. Like you said, so many people have the potential to see enormous improvements in their health and well-being if they just thought about their GM when making dietary decisions. Certainly more to come on this topic in the future... Thanks for watching!! 🙏🌱 - Dylan
Thank you for this absolutely fantastic series. The pacing, narrative, depth and clarity are all just great! Knowing a lot about a subject is one thing; being an effective educator is a whole other skill set. I don't know if you studied to be a teacher, but you have a talent for it. I would love to see more content about tea. If you look into how to game the youtube algorithm a bit more effectively I'm sure this channel would cannonball to great fame ;) I did want to mention something about some of the Japanese studies you discuss. As you are undoubtedly aware, these mostly studied matcha. I feel it would be appropriate to underline that with matcha the soup contains the dried, pulverized leaf. This may increase the bioavailability of many active components significantly, as the body is able to extract more of them during digestion than what is possible with only hot water. In addition, the surface area is simply huge when brewing matcha compared to whole leaf tea. Also worth noting, I feel, is that the observed effects were restricted to fresh matcha, although I do not remember exactly how fresh.
As usual great content, I do have question, how much tea is ok/ safe to drink a day? I was searching the net and I'm getting anywhere between 5-15 cups a day.Would appreciate and comment or point me to the right video.cheers.
great video! i already learned allot from all the amazing content you provided, after watching the first chapter i went to a special store, and bought gren,white and black teas just to see what is the actual diference and i never knew that there was so much difference between them.... so interesting :) i also noticed a hint of smokiness which i never tasted when i bought regular low grad tea, so again big thank for opening my eyes to this interesting topic, will continue to watch your next views
I’d love to hear about tea’s interaction w/ sleep quality. Not just whether l-Theanine calms you down before bed or not, but rather a discussion of the chronic effects of tea, the alterations in body + brain, and how these contribute to quality of sleep. Im curious whether something like this could be studied w/ reasonable controls. I’d be curious to see if a population of tea drinkers consistently report higher or lower hours of sleep as opposed to non-tea or no-caffeine drinkers and how this could relate to sleep quality.
I would be interested to know if brewing a mix of different loose teas cause an synergistic effect or if there are any herbs that can be brewed with teas to create increased health/psychoactive effects? Like could adding lavender and chamomile to a matcha with high Ltheanine content be much more relaxing or could mixing black tea with ginseng increase alertness? Could you discus the aromatic qualities and affects of different teas maybe like an entourage effect ?
Great video, this was really informative! I just had a question - is there any science regarding the best methods of brewing, water temperature, timing etc to extract the most catechins and beneficial compounds from the tea? Thanks!
Hey Liz, glad you liked it! 😊🌱 So, in Chapter 5 of the Masterclass and in a previous 2-part blog post I dug into how water temperature and time affect catechin extraction from tea leaves (full video and blog linked below). Basically, the takeaway is that longer hotter infusions will extract more catechins... but may also create an exceedingly bitter/astringent brew in the process. There are truly a ton of catechins in tea leaves already and if you just set out to make a palatable and balanced tea infusion you will already be ingesting an enormous amount of catechins. Personally, I recommend just re-infusing the tea leaves several times at a water time/temperature that brews good-tasting cups of tea, however the technical answer to your question according to experimental data is that longer and hotter infusions lead to more antioxidant compound extraction. If you want the best of both worlds, maybe try experimenting with longer and hotter infusions until you get to the point where the tea is too strong then dial it back a touch 😜🌱🍵 Hope this helped! Keep me posted :) -Dylan Chapter 5: ua-cam.com/video/L_lhIDXjf4M/v-deo.html Blog: wumountaintea.com/2020/07/30/a-hot-take-on-tea-extraction-science-part-1/
haha Great!! I got you covered 😄🍵🌱 I'm just working on another series of Tea Health Benefits video right now! I like the anti-diabetes/blood sugar-regulating topic - thanks for the idea 😊🙏🌱 Thanks for watching and commenting 😊🍵🙏 - Dylan from Wu
I would love to know more about the availability of L-Theanine in the various styles of tea. Especially puerh, maocha vs aged sheng. Does ripe puerh lose all or still contain some? Also why does gushu sheng have a higher chazui affect vs young trees? What is in gushu puerh vs gyokuro that makes the puerh feel more trippy? What all in tea gives this tea drunk feeling besides the L-Theanine?
Hey Robert, unfortunately much of the psychoactive properties of tea (particularly gushu sheng) remains a mystery. Personally and anecdotally, I know precisely what you're talking about with the higher chazui effect of gushu sheng puer, however this altered state of consciousness is difficult to pinpoint with brain imaging machinery (or at least the experiment simply has not been done yet). I imagine that tea alkaloids (there are 4 in tea: caffeine, theobromine, theophylline, theacrine) play a significant role, as these tea alkaloids all are psychoactive in distinct ways, some more energizing and some more calming. Additionally, tea catechins (particularly EGCG) have been shown to bring about calm + attentive effects akin to the chazui effect (research linked here: pubmed.ncbi.nlm.nih.gov/22127270/). My GUESS regarding gushu tea is simply that due to the long thick root structures and nutrient-rich soil environment that these trees are typically cultivated in, the tea leaves are actually just more abundant in the numerous critical psychoactive compounds, rather than there being distinct or different psychoactive compounds that other tea leaves do not possess. This is merely a hunch. I would love to see some brain imaging research of people tea drunk on gushu sheng puer... I bet there would be some really interesting findings. Thanks for the comment 🌱🙏🍵
First of all thank you for all the videos that you make! Being a heavy tea drinker myself I still have to point out that it would be fair if you could mention not only "positive" side of nutrients malabsorption due to enzymes inhibitors in tea, but also the iron and vitamins malabsorption. For some people it could be crucial. And maybe recommend to drink tea in between their meals if that is a concern. Also curious on your thoughts on oxalates in teas. Thank you:)
Hey, you're welcome!! Thanks for watching 😃🍵🙏 I completely agree with your thoughts on presenting the potential risks of enzyme inhibition by tea polyphenols. This topic was actually already in the next two or three videos on my to-do list. The video will be laying out the specific vitamins and minerals most significantly chelated by tea polyphenols, and thus those that should be monitored closely and perhaps supplemented if you are a heavy tea drinker. I will also be covering risk mitigation for heavy metal and pesticide exposure. As for oxalates, tea leaves contain high concentrations of oxalates on a per leaf weight basis, which can appear concerning. However, since even the heaviest of tea drinkers only consume ~15-20 grams of water extract per day, the levels consumed remain below the level considered to be a risk factor for kidney stones. I gathered three research articles for you to review if you would like to dive deeper into this topic. #1: An assessment in kidney stone-prone individuals that found no increased risk for daily green tea drinkers compared to non-tea drinkers (and actually reduced risk in one relevant category): www.mdpi.com/2072-6643/11/2/256 #2: Measurement of oxalate levels from 52 different green tea samples from China that found oxalate levels ranging from 8.3 to 139.8 mg/l (that's a pretty big range! you might want to dive into that one a bit). Generally the study concluded that "Patients at risk for recurrent stone formation should take into account the oxalate content of green tea," however that is not really a firm recommendation or conclusion about anything. Nonetheless, they seem to say may be worth paying attention to. link.springer.com/article/10.1007/s00240-009-0245-x #3: Assessment of oxalate levels from Iranian Black Tea. "The oxalate content of Iranian consumed black tea after different brewing times and different dilution was below the recommended levels. Therefore, it seems that consumption of black tea several times per day would not pose significant health risk in kidney stone patients and susceptible individuals." www.ncbi.nlm.nih.gov/pmc/articles/PMC3963632/ These are several data points for you to consider. Please feel free to review them, offer your thoughts, and come back with other studies you come across on the topic. I hope you can rest assured that I am fully dedicated to reporting the science of tea completely and honestly. My channel is still young, so I have not gotten to many important topics, but in due time I think that will be clear 😊🍵🌱 I hope you subscribe to the channel so you can stay in the loop on the enzyme inhibition video and offer me your feedback on it when it comes out. Best, Dylan from Wu
@@wumountaintea Thank you for detailed reply! I checked all the links and what’s interesting is that conventional medicine see oxalate as a kidney stone issue only, but it seems like some people have bigger problems with it. In case you gonna look deeper into this topic in preparation for your next post I suggest you to listen to Sally Norton interviews here on YT or read her book ‘toxic superfoods’. She mentioned tea many times. Kind regards 🍵🙏
@@wumountaintea. I don’t know how the herb Chanca Piedra (Stone Breaker Tea) acts with oxalates but since having a gall bladder attack, but not wanting surgery, I have begun including a very tiny amount of Chanca Piedra in pill or tea form in my diet infrequently. This has been like a miracle regarding my gall bladder! 🕊️
I can only ask one thing: how the heck your subscriber number is so low? Same for views... Your videos are amazing, very insightful and I think you'd be a great lecturer, if you're not one yet 😎 Yet, I'd like to ask about an additional thing: what about all those health benefits of tea when brewing a kombucha? I've watched your video on kombucha, but it's still not that clear to me: will the fermentation process degrade any of this positive compounds found in the tea used and if so - to what degree? Once again, big thanks for your videos, big fan straight in the first minute 😎 - Max
Thank you Max!! That means a lot to me 🙏🌱🍵😊 Subscriber count is creeping up slowly, but I have only been making videos seriously for under a year, so the channel is still young I think. So the kombucha fermentation does change the antioxidant molecules themselves (by breaking them down slightly), however the breakdown products appear to still be beneficial. In fact, when you drink normal tea, most of the antioxidants get broken down into these smaller products anyway, so many health benefits from normal tea are in fact mediated by these antioxidant breakdown products. So, yes, kombucha fermentation does "degrade" them, however the products of degradation are still beneficial... Does that make sense? Let me know 😊🌱🍵 Dylan
Hi Jeanne, all orders go through Wu Mountain Tea .com (no spaces, but UA-cam doesn’t like creators putting links in the comments). You can DM or email me with questions 🤗🌱🍵 Dylan
I sometimes get acute bowel evacuations, but since stopping my tea intake, they are almost gone, and clme back if I try tea again. Since I love tea, this sucks. Any insights, maybe some types are less activating? (I've been to a physician and dietist about this.)
White low grade, green commercial, black darjeehling, ceylon, classic teabags, organic lapsang. I've ordered a couple of higher quality teas now (silver needle, a japanese green, first flush high alt. darjeeling).
19:12 correction: not 10% human but 2/3rd human. The 10% human thing was a miscalculation. Different types of sells in our body have different size and weight and the microbes have different population density through the digestive system. Most of them being on just a small portion of Our GI tract. When these taken account then microbe vs human cell count comes down to about 3rd of us being microbes. Still a lot, though and doesn't negate anything you say
Also, about healthy microbione in people who are drinking various types of teas... I am sure, that teas contributed to that. But they most likely don't eat in McDonalds either... So... It would be nice to see studies with healthy eaters vs healthy eaters + teas. But I know, it is tricky to do studies like that and no one wants to waste money on researching tea, when it is a cheap plant (compared to pharma developed meds). Or... Seeing how change could be achieved with American diet + teas 1-2 times a day. Maybe that kind of study is more realistic. Cause...we can research with rats all we want, but at the end of the day they don't have the same metabolism and GI system. E.g. soy is cancer producing for them while cancer preventive for us...
15:50 - 18:35 I do think it would be wise to do more research on weight and "obesity". A lot of what we pass around as fact isn't true and is being actively debunked with good quality science. Upwards of 98% of people gain all, and frequently more, weight back than lost after dieting ends (and it always ends). This would include temporary weight loss from tea. *Weight stigma* has been shown to impact health more than food choice and weight. "Obesity" isnt a disease. As a matter of fact, the meeting when that was decided on, there was push back on it from the scientific community because "disease" isn't well defined and there wasnt evidence to suggest that being fat was disease of any kind. Your conscious choices only impact about 20%-30% of your health. The vast majority of it is out of your control. The stress reduction from tea likely is the key to it's touted benefits, and that likely exists across all body sizes.

Maybe because I never bothered to read long articles about its health benefits, I would rather read articles about its history or various brewing techniques. But this video... this has actually made me interested in the health aspect as well!! As usual, thanks for providing us with great content!!
Anas,
That's great to hear! 😃🌱
It's fascinating how tea can entice people for so many different reasons. My goal in creating the Masterclass was to provide 8 unique lenses through which people can understand and appreciate tea. At the outset, people tend to have their favorite sub-topics, but, like you, tea lovers are often surprised to learn that new aspects of tea intrigue them as well.
Personally, Tea and Health might be my favorite sub-topic of tea (perhaps a tie with sustainable tea field management). But, in creating the Masterclass I also realized that Tea History is far more interesting than I had previously thought.
In tea, we have a lifetime of discovery and appreciation at our fingertips.
Thanks as always for watching and commenting, and I look forward to hearing from you in future videos 😊🌱🍵
Best,
Dylan
Great video 👌 I'm from INDIA & here Tea is part of every Morning or Evening Breakfast ☕
awesome, I love Indian tea I hope to explore it and talk about it more in the future 💚
Super high quality summary, especially the digestive enzyme enhibition kind of blew my mind! Super cool to find such a sound breakdown of the recent science about this, esp as a pharma sci myself it's frustrating how most info about this is surface level in one of the 2 extremes you mentioned (due to which I was honestly sceptical biased towards the 'no effect' group). I don't think I've ever heard of the bioactive EGCG metabolites forming due to gut microbiome. Admittedly I never felt like diving into pubmed for this info myself lol. Good to see that there's decent indications that the daily 煎茶 is doing some good.
Nice comment 👌 Right, surface level on one of the two extremes (the lazy perspectives). The microbiome-mediated alterations of the tea polyphenols is a hot research area right now. It appears to be really important but wildly unpredictable/variable. Will be reporting more on it as more research comes out! 🌱🍵
-Dylan
This masterclass as a whole is a gem 💎, you dive deep into the subjects while still being clear and an outstanding teacher. Glad I found your channel ;)
Another great video! You have an uncanny way of presenting complex scientific info in an easily digestible way.
thanks! 😊
Fascinating stuff..
thanks... favorite part was the outro music ;)
This 8-chapter Masterclass on tea is fabulous. Extremely well researched and presented, and a joy to watch!
Thank you so much for the great video, Dylan! Would you be able to provide the list of articles that you referred to in this video?
I had no idea there were so many health effects of tea. How wonderful! Thanks for sharing this information. I'd love to hear more about the impact of tea on cancer prevention, treatment, and skin health. Also, it would be great to have links or a list of citations for the video. Did you say that was in the PDF? Thanks again!
Hey E,
Sure, I am working on a tea and skin health video now, and the cancer topic will be covered too at some point.
As for a complete bibliography, the best I have are the on-screen citations in the form of the article title and author shown on the screen as I discussed the findings. If I missed an on-screen citation and you would like to check on the source of the thing I am saying then just let me know and I can send you the article that I referenced for whatever I was talking about. I made sure that everything said in this video was supported by peer-reviewed research, so there are definitely research articles relating to everything in the video. Just let me know :)
Thanks for watching and commenting! Hope you're enjoying the Masterclass 😊🌱🍵🙏
Dylan
Another insightful video - science is everything! I knew that tea was good for helping out with thise glucose spikes but actually learning the mechanism behind it was minsblowing! It will be very interesting to have a video on tea compounds' effects on skin and a big one for me is female reproductive organs.
Ok I like to refer to that glucose spike inhibition here.I did notice since having few cups of oolong every day,I don't have energy crashes after especially white rice heavy meals,so feeling actually more tired and yawning after this meals,which is somehow normal response of your body directing all resources to digestion.super intresting
Love this channel, glad i found it
Thanks for the video. What green teas are the best for the brain?
Your tea videos are awesome. I never thought I would become enthusiastic about tea, but who knew? I’m ready to shop for some first flush tea. You have presented a lot of information which I am enjoying through your excellent videos. Thank you.
Dylan. Your videos are amazing. I would love to know more about
- mood enhancing and depression and tea
- tea and anti aging for the skin
Thank you
I love this series! I would love to watch a video where you talk about which teas are good for skin/ hair health. Teas that help clean the lungs and heal
Amazing content.
Nice~! I've been so excited for this, I refreshed my UA-cam like 5 times today >.>
There's SO MUCH misinformation about this where I live, so this is amazing content and I will be forwarding this to a bunch of people.
Great!! Thanks for watching bro 😊🍵 Yeah plenty of disinformation on this topic where I live too... so I hope this video can help nudge people in the right direction. It's really a complex topic and new things are being discovered all the time... but a main goal of this chapter was just to demonstrate how I personally approach the topic of tea and health - which is with a relatively open mind but still centered around scientific experimental findings. Cheers brotha!
I can attest that having suffered with food sensitivities for a long while, as soon as I took on tea drinking, most of my digestive issues went! Coincidence...?
That's great!! I recently finally got my own brother to replace his coffee habit with tea (we're starting with Ripe Puer), and he saw his heartburn issues reduce almost immediately. These stories (and the research to back them up) are my biggest motivators to keep spreading the word on tea. Thanks for the comment Gabriel! 🌱🍵🙏
This series is amazing. You explain everything very very well!
Can you explore more of the benefits of drinking tea and the effects it has on reversing the damage of brain cells and neurodegenerative disorders. Basically how tea can help create a healthy brain biome. If that's a thing. Thanks for your videos they are really informative and entertaining!
Namaste!
Wow, I am so glad to have found your masterclass! This is just mind-blowing ❤
A big hearty thank you for making this knowledge available to us, Dylan. You are an outstanding teacher!
I have found a treasure today that I can share with my community here for deeper wisdom ❤❤
From India
Another awesome video. Thank you for doing these......interesting too....think about all these young people I hear about with depression....yet they eat out almost every day...and any tea they might drink is bottled garbage. Gut microbiome is so important.
Thanks!! Glad you liked it 😊🍵 The gut microbiome is SO important - if people take one thing away from this video I hope it's just that we have to be looking after our GM. Like you said, so many people have the potential to see enormous improvements in their health and well-being if they just thought about their GM when making dietary decisions. Certainly more to come on this topic in the future... Thanks for watching!! 🙏🌱
- Dylan
Thank you for this absolutely fantastic series. The pacing, narrative, depth and clarity are all just great! Knowing a lot about a subject is one thing; being an effective educator is a whole other skill set. I don't know if you studied to be a teacher, but you have a talent for it. I would love to see more content about tea. If you look into how to game the youtube algorithm a bit more effectively I'm sure this channel would cannonball to great fame ;)
I did want to mention something about some of the Japanese studies you discuss. As you are undoubtedly aware, these mostly studied matcha. I feel it would be appropriate to underline that with matcha the soup contains the dried, pulverized leaf. This may increase the bioavailability of many active components significantly, as the body is able to extract more of them during digestion than what is possible with only hot water. In addition, the surface area is simply huge when brewing matcha compared to whole leaf tea. Also worth noting, I feel, is that the observed effects were restricted to fresh matcha, although I do not remember exactly how fresh.
Over a year old and not a single dislike. As it should be 🙏
As usual great content, I do have question, how much tea is ok/ safe to drink a day? I was searching the net and I'm getting anywhere between 5-15 cups a day.Would appreciate and comment or point me to the right video.cheers.
great video!
i already learned allot from all the amazing content you provided, after watching the first chapter i went to a special store, and bought gren,white and black teas just to see what is the actual diference and i never knew that there was so much difference between them.... so interesting :)
i also noticed a hint of smokiness which i never tasted when i bought regular low grad tea, so again big thank for opening my eyes to this interesting topic, will continue to watch your next views
I’d love to hear about tea’s interaction w/ sleep quality. Not just whether l-Theanine calms you down before bed or not, but rather a discussion of the chronic effects of tea, the alterations in body + brain, and how these contribute to quality of sleep.
Im curious whether something like this could be studied w/ reasonable controls.
I’d be curious to see if a population of tea drinkers consistently report higher or lower hours of sleep as opposed to non-tea or no-caffeine drinkers and how this could relate to sleep quality.
Absolutely stellar as always. Really thankful that you are doing this! Keep trucking!
Awesome! Thanks for watching 😊 More vids on the way 🍃
Simply the best content about tea. Thanks, Dylan, I'm your fan! ❤
Köszönjük!
Wow, very informative video. Now I love tea more🎉
Are there any studies about the relationship or correlation between chronic diseases and tea consumption to improve them?
I would be interested to know if brewing a mix of different loose teas cause an synergistic effect or if there are any herbs that can be brewed with teas to create increased health/psychoactive effects? Like could adding lavender and chamomile to a matcha with high Ltheanine content be much more relaxing or could mixing black tea with ginseng increase alertness? Could you discus the aromatic qualities and affects of different teas maybe like an entourage effect ?
Great source of knowledge!
Do you have any thoughts on tea consumption and Gastroesophageal reflux disease (GERD)?
Best regards!
i drink tea everyday, can i add roiboos to my teapot and expect to have added benefits or do you think they will cancel?
Great video, this was really informative! I just had a question - is there any science regarding the best methods of brewing, water temperature, timing etc to extract the most catechins and beneficial compounds from the tea? Thanks!
Hey Liz, glad you liked it! 😊🌱 So, in Chapter 5 of the Masterclass and in a previous 2-part blog post I dug into how water temperature and time affect catechin extraction from tea leaves (full video and blog linked below). Basically, the takeaway is that longer hotter infusions will extract more catechins... but may also create an exceedingly bitter/astringent brew in the process. There are truly a ton of catechins in tea leaves already and if you just set out to make a palatable and balanced tea infusion you will already be ingesting an enormous amount of catechins. Personally, I recommend just re-infusing the tea leaves several times at a water time/temperature that brews good-tasting cups of tea, however the technical answer to your question according to experimental data is that longer and hotter infusions lead to more antioxidant compound extraction. If you want the best of both worlds, maybe try experimenting with longer and hotter infusions until you get to the point where the tea is too strong then dial it back a touch 😜🌱🍵
Hope this helped! Keep me posted :)

I want to know it all! Any and all health benefits. Heart health, brain health, anti diabetes, weightloss...
haha Great!! I got you covered 😄🍵🌱
I'm just working on another series of Tea Health Benefits video right now! I like the anti-diabetes/blood sugar-regulating topic - thanks for the idea 😊🙏🌱
Thanks for watching and commenting 😊🍵🙏
- Dylan from Wu
Great video and great series. Can you do a video about the antioxidative effects of tea? that would be really interesting
I would love to know more about the availability of L-Theanine in the various styles of tea. Especially puerh, maocha vs aged sheng. Does ripe puerh lose all or still contain some? Also why does gushu sheng have a higher chazui affect vs young trees? What is in gushu puerh vs gyokuro that makes the puerh feel more trippy? What all in tea gives this tea drunk feeling besides the L-Theanine?
Hey Robert, unfortunately much of the psychoactive properties of tea (particularly gushu sheng) remains a mystery. Personally and anecdotally, I know precisely what you're talking about with the higher chazui effect of gushu sheng puer, however this altered state of consciousness is difficult to pinpoint with brain imaging machinery (or at least the experiment simply has not been done yet). I imagine that tea alkaloids (there are 4 in tea: caffeine, theobromine, theophylline, theacrine) play a significant role, as these tea alkaloids all are psychoactive in distinct ways, some more energizing and some more calming. Additionally, tea catechins (particularly EGCG) have been shown to bring about calm + attentive effects akin to the chazui effect (research linked here: pubmed.ncbi.nlm.nih.gov/22127270/). My GUESS regarding gushu tea is simply that due to the long thick root structures and nutrient-rich soil environment that these trees are typically cultivated in, the tea leaves are actually just more abundant in the numerous critical psychoactive compounds, rather than there being distinct or different psychoactive compounds that other tea leaves do not possess. This is merely a hunch. I would love to see some brain imaging research of people tea drunk on gushu sheng puer... I bet there would be some really interesting findings. Thanks for the comment 🌱🙏🍵
This episode makes me wish there would be monthly Tea Science News sort of same style Dr Becky does her summaries in astrophysics.
The yunnan moonlight white, favorite tea ever… so far
that's a good one!! 🌚🌱👌
I loved this.
Great! Thanks for watching 🤗 plenty more like this coming 🌱🍵
How do I get good quality tea? And good sourced with no chemicals
This is just great content! :)
As a tea lover, how do you deal with the risk of iron deficency? I'm actually assuming iron therapy :(
Thanks!
Have you ever spoken about cold brewed tea? Could it be as good as hot water brewing?
whats the best few teas?, green tea?, matcha tea? EXTREMLY alot of tea's out there.
Fluorine apparently is another mineral found in China-grown tea; often viewed as a dental advantage.
First of all thank you for all the videos that you make! Being a heavy tea drinker myself I still have to point out that it would be fair if you could mention not only "positive" side of nutrients malabsorption due to enzymes inhibitors in tea, but also the iron and vitamins malabsorption. For some people it could be crucial. And maybe recommend to drink tea in between their meals if that is a concern. Also curious on your thoughts on oxalates in teas. Thank you:)
Hey, you're welcome!! Thanks for watching 😃🍵🙏
I completely agree with your thoughts on presenting the potential risks of enzyme inhibition by tea polyphenols. This topic was actually already in the next two or three videos on my to-do list. The video will be laying out the specific vitamins and minerals most significantly chelated by tea polyphenols, and thus those that should be monitored closely and perhaps supplemented if you are a heavy tea drinker. I will also be covering risk mitigation for heavy metal and pesticide exposure.
As for oxalates, tea leaves contain high concentrations of oxalates on a per leaf weight basis, which can appear concerning. However, since even the heaviest of tea drinkers only consume ~15-20 grams of water extract per day, the levels consumed remain below the level considered to be a risk factor for kidney stones. I gathered three research articles for you to review if you would like to dive deeper into this topic.
#1: An assessment in kidney stone-prone individuals that found no increased risk for daily green tea drinkers compared to non-tea drinkers (and actually reduced risk in one relevant category): www.mdpi.com/2072-6643/11/2/256
#2: Measurement of oxalate levels from 52 different green tea samples from China that found oxalate levels ranging from 8.3 to 139.8 mg/l (that's a pretty big range! you might want to dive into that one a bit). Generally the study concluded that "Patients at risk for recurrent stone formation should take into account the oxalate content of green tea," however that is not really a firm recommendation or conclusion about anything. Nonetheless, they seem to say may be worth paying attention to. link.springer.com/article/10.1007/s00240-009-0245-x
#3: Assessment of oxalate levels from Iranian Black Tea. "The oxalate content of Iranian consumed black tea after different brewing times and different dilution was below the recommended levels. Therefore, it seems that consumption of black tea several times per day would not pose significant health risk in kidney stone patients and susceptible individuals." www.ncbi.nlm.nih.gov/pmc/articles/PMC3963632/
These are several data points for you to consider. Please feel free to review them, offer your thoughts, and come back with other studies you come across on the topic.
I hope you can rest assured that I am fully dedicated to reporting the science of tea completely and honestly. My channel is still young, so I have not gotten to many important topics, but in due time I think that will be clear 😊🍵🌱
I hope you subscribe to the channel so you can stay in the loop on the enzyme inhibition video and offer me your feedback on it when it comes out.
Best,
Dylan from Wu
@@wumountaintea Thank you for detailed reply! I checked all the links and what’s interesting is that conventional medicine see oxalate as a kidney stone issue only, but it seems like some people have bigger problems with it. In case you gonna look deeper into this topic in preparation for your next post I suggest you to listen to Sally Norton interviews here on YT or read her book ‘toxic superfoods’. She mentioned tea many times. Kind regards 🍵🙏
@@wumountaintea. I don’t know how the herb Chanca Piedra (Stone Breaker Tea) acts with oxalates but since having a gall bladder attack, but not wanting surgery, I have begun including a very tiny amount of Chanca Piedra in pill or tea form in my diet infrequently. This has been like a miracle regarding my gall bladder! 🕊️
Do you have any information about the fluoride that tea collects from soils?
I can only ask one thing: how the heck your subscriber number is so low? Same for views... Your videos are amazing, very insightful and I think you'd be a great lecturer, if you're not one yet 😎
Yet, I'd like to ask about an additional thing: what about all those health benefits of tea when brewing a kombucha? I've watched your video on kombucha, but it's still not that clear to me: will the fermentation process degrade any of this positive compounds found in the tea used and if so - to what degree?
Once again, big thanks for your videos, big fan straight in the first minute 😎
- Max
Thank you Max!! That means a lot to me 🙏🌱🍵😊 Subscriber count is creeping up slowly, but I have only been making videos seriously for under a year, so the channel is still young I think.
So the kombucha fermentation does change the antioxidant molecules themselves (by breaking them down slightly), however the breakdown products appear to still be beneficial. In fact, when you drink normal tea, most of the antioxidants get broken down into these smaller products anyway, so many health benefits from normal tea are in fact mediated by these antioxidant breakdown products.
So, yes, kombucha fermentation does "degrade" them, however the products of degradation are still beneficial...
Does that make sense? Let me know 😊🌱🍵
Dylan
You are amazing.
I drink so much tea I will basically outlive my grandchild
Best tea or tisane for later in the day/evening?
AAAAAAWesome yoooooo Great Video.....!!!!!
You forgot to say "One Love" this episode...One Love🤙
I appreciate it! Let the people know 1️⃣🖤
What tea type is being referred to here? Black tea? Green tea?
Do you know of a rich amino acid tea in uk. My husbavnd has so much stress at work
How come this isn’t in schools ? We all know why
Is drinking with milk also beneficial???
Milk diminishes the antioxidant properties of tea.
How do I order wu mountain tea?
Hi Jeanne, all orders go through Wu Mountain Tea .com (no spaces, but UA-cam doesn’t like creators putting links in the comments). You can DM or email me with questions 🤗🌱🍵
Dylan
is it true that white tea is the healthiest?
or the richest in anti-oxidants.
I sometimes get acute bowel evacuations, but since stopping my tea intake, they are almost gone, and clme back if I try tea again.
Since I love tea, this sucks. Any insights, maybe some types are less activating?
(I've been to a physician and dietist about this.)
What type of tea were you drinking? Try to be as specific as possible
White low grade, green commercial, black darjeehling, ceylon, classic teabags, organic lapsang.
I've ordered a couple of higher quality teas now (silver needle, a japanese green, first flush high alt. darjeeling).
How about lipton tea?
White tea?
❤
We have typhoo tea in uk. It must be so bad
Diversi-tea, creativi-tea and 🌈 🏳️🌈 🎨
Why do I have heartburn after drinking black tea?
19:12 correction: not 10% human but 2/3rd human. The 10% human thing was a miscalculation. Different types of sells in our body have different size and weight and the microbes have different population density through the digestive system. Most of them being on just a small portion of Our GI tract. When these taken account then microbe vs human cell count comes down to about 3rd of us being microbes. Still a lot, though and doesn't negate anything you say
Also, about healthy microbione in people who are drinking various types of teas... I am sure, that teas contributed to that. But they most likely don't eat in McDonalds either... So... It would be nice to see studies with healthy eaters vs healthy eaters + teas. But I know, it is tricky to do studies like that and no one wants to waste money on researching tea, when it is a cheap plant (compared to pharma developed meds).
Or... Seeing how change could be achieved with American diet + teas 1-2 times a day. Maybe that kind of study is more realistic. Cause...we can research with rats all we want, but at the end of the day they don't have the same metabolism and GI system. E.g. soy is cancer producing for them while cancer preventive for us...
I just went through all the different teas I have in my house. Some are good some not so good.
So bubble teas aren’t thaaat bad for you if you get the kind with real tea.

🍵🤘💚
Dammm. The tea made him speak another language
Ok.
🍵👌
15:50 - 18:35 I do think it would be wise to do more research on weight and "obesity". A lot of what we pass around as fact isn't true and is being actively debunked with good quality science. Upwards of 98% of people gain all, and frequently more, weight back than lost after dieting ends (and it always ends). This would include temporary weight loss from tea.
*Weight stigma* has been shown to impact health more than food choice and weight.
"Obesity" isnt a disease. As a matter of fact, the meeting when that was decided on, there was push back on it from the scientific community because "disease" isn't well defined and there wasnt evidence to suggest that being fat was disease of any kind.
Your conscious choices only impact about 20%-30% of your health. The vast majority of it is out of your control.
The stress reduction from tea likely is the key to it's touted benefits, and that likely exists across all body sizes.
Thats how that guy survived just by drinkin tea for years..
