Tea Consumption Is Associated With Slower Biological Aging 

Thanks James, I'm familiar with that paper-one reason that I prefer the paper in the video instead is because of the association with biological age, or more specifically, the composite of 15-18 biomarkers. That, to me, is a step-up in evidence above ACM risk.

>1-2 coffee, 3+ cups of tea appearing optimal. Good to hear! Surely, adding cocoa will make me live forever.

@jaym9846 No, you have to add exercise and red light therapy for that!

I wonder how much of this is actually drinking WARM WATER, not tea aka some brown/green water.

That's a fair point, there could be a substitution effect. I believe you can adjust for that in most of these studies though, as the questions in these surveys usually addresses other drinks, including sugary soda.

I've been doing something similar, except I use peppermint instead of lemon ginger. What are you basing your selection on? Variety of anti-oxidants?

Thanks @spiritof76forever81!

Thanks a great point, @sandroalmeida3434, we'll need to wait for RCTs to test those hypotheses...

The study was done in China where they typically don’t drink tap water, they drink bottled water, or boiled water

@@peacefuldragon1831 Also UK. Most Brits drink tap water.

Relative to the polyphenols in tea i think its nothing, theres nothing to degrade by boiling, not much to destille, maybe some microplastics, if you want clean water you need clean RO system

Do you buy this as a mix of leaves?

matcha, no doubts

@@jakubruszczyk2053agreed

This is my problem with every new study. Im already taking Astaxanthin, eat lots of carrots, fruits, mushrooms, tea, etc. Will introducing NAC and other compounds really help? We need to solve the antioxidant puzzle once and for all...

I heard somewhere that green tea/macha is great for antioxidants and black tea (Chinese?) helps with blood cell creation in the marrow.. so these were 2 great teas to consume

It seems like any tea that is from a tea leaf, not herbal teas. They are all rich in polyphenols.

On 1) the N for the dietary data is well powered so that is OK, except for the well known recall bias problems with those surveys. On 3) we can't use location as a reason as there are many good studies from china. On 2) there is good reason it ended up in a fringe journal. And if I were reviewing this it would be the use of biological age calculators as a surrogate endpoint for something definitive like mortality. To the authors credit they used two cohorts which was a good idea. Although you can see that led to muddy waters in the not very convincing CMEC and UKB tea consumption - BA acceleration figures.

The correlation, although significant is low at ~0.1. Could be reverse causation?

@@jamesgilmore8192I would think so. The (chronically ill) elderly get more bloodwork done, thus are put on supplements more so than the average person in their 50s.

Agreed, matcha is more carefully harvested so I’m sure that would indicate less heavy metals

Same. Black tea - gentle caffeine, versus crazy shot of espresso.

Not knocking the black tea. That said, if you are looking for health benefits white tea is much healthier.

@@proman84 Healthier in what sense? I drink black tea cos I need some caffeine, and green tea gives me brain fog.

Any combination of those in the video would be a good approach. it doesn't have to be one vs another...

is this related to grean tea ? which tea ?@@conqueragingordietrying1797

Timestamps are also in the pinned comment...

The result said you don't need more than 3 cups a day.

Most people in India and China drink irrespective of a kettle 😀

@@madisonone8929 Thanks for that clarification. Are they cold brewing?

@@ChessMasterNate When I said "these studies" I was also referring to the other papers on green tea that suggests 4 or 5 as optimal. I didn't find this particular study more compelling than most of the previous work on the topic.

Yeah i don't really see tea as a luxury food....

Hi @KoiRun50, I use a Big Berkey filtration system

@@conqueragingordietrying1797what do you think about the berkley lawsuit against the company?

Here in the UK, drinking tea is a very social event. It could be a tea break with coworkers or on the sofa with a family member. I wonder if social inclusion also helps slower the biological age!

Only heard from tea extract. Could you post the source about regular tea consumption causing hepatitis? I typically do liver tests whenever I change regimen

Do you have any references for that?

@@jamesgilmore8192 Check out his videos. He even charted and ranked food and beverage according to their anti oxidant, biogenesis, angiogenesis values etc

A story for another day...

Total tea consumption was evaluated, not the individual teas...

@@conqueragingordietrying1797 Bummer. I expect quite some differences there.

imo, good. It's a staple in my diet, 20oz/d

Proline decomposes anthocyanides. A study shows that some effects lasts for 3 days. But salvia also decomposes anthocyanides.... ATM i do not relay too much on that data.

I remember that study as well, although I thought it was coffee!

Thanks @SilverFan21k!

Cheer up. It may still hold true for green tea, as one tea may skew the overall results of the studies referenced. The teas studied have different properties. For example: "Green and black tea both contain caffeine, a known stimulant. Green tea contains less caffeine than black tea - about 35 mg per 8-ounce (230-ml) cup, compared with 39-109 mg for the same serving of black tea ( 2 , 8 , 9 ). " Source: Green Tea vs Black Tea: Which One Is Healthier? - Healthline Only one study conducted in the Fukuoka Diabetes Registry including 4923 patients (2790 men and 2133 women) with type 2 diabetes followed for 5.3 years revealed that the combined consumption of ≥ 2 cups/day of coffee and ≥ 4 cups/day of green tea had 63% lowest risk for all-cause mortality [14]. Furthermore, the studies on Green Tea alone, tend to show that 4 or more cups is better. Chen, Y., Zhang, Y., Zhang, M. et al. Consumption of coffee and tea with all-cause and cause-specific mortality: a prospective cohort study. BMC Med 20, 449 (2022). Over the 11 years of follow-up (follow-up rate, 86.1%), 4,209 participants died. Over the seven years of follow-up (follow-up rate of 89.6%), 892 participants died of cardiovascular disease and 1,134 participants died of cancer. Green tea consumption was inversely associated with mortality due to all causes and due to cardiovascular disease. The inverse correlation for all-cause mortality was greater in women (P = 0.03 for interaction with sex). In men, the multivariate hazard ratios of mortality due to all causes associated with different green tea consumption frequencies were 1.00 (reference) for less than 1 cup/d, 0.93 (95% confidence interval [CI] 0.83-1.05) for 1-2 cups/day, 0.95 (95% CI 0.85-1.06) for 3-4 cups/d, and 0.88 (95% CI 0.79-0.98) for 5 or more cups/d (P = 0.03 for trend). The data for women were 1.00, 0.98 (95% CI 0.84-1.15), 0.82 (95% CI 0.70-0.95), and 0.77 (95% CI 0.67-0.89), respectively (P < 0.001 for trend). Kuriyama S, et al. Green tea consumption and mortality due to cardiovascular disease, cancer, and all causes in Japan: The Ohsaki study. JAMA 2006;296:1255-1265.

I'm guessing that as it is with most things, dose matters. There has been reports of people who consumed a lot of tea that had liver toxicity.

@@bogrunbergeryea especially with green tea and more so for women than men….

@@bogrunbergerDose does matter (Drinking too much water will kill you.) However, previous studies have found that greater or equal to 4 cups of green tea had the lowest all cause mortality compared to lower doses. Are the studies presented in the video better than previous studies? Maybe, maybe not.

@@jackbuaer3828 i drink lots of green tea, i go on intuition on this one, i believe it is a wonder elixir. the tea plant itself is miraculous, red and black tea is also good :)

Link?

@@johnnielsen5493 I tried searching the video, I couldn't find it but I'd still suggest you to watch his tiny playlist of short videos on Tea 🍵 ru-vid.com/group/PL5TLzNi5fYd9Udht-DegCDcPlJI1A4d51 Packed with research

i used to empty 2 teabags of green tea into a cup, pour boiling water in the cup, let it sit for an hour until cooled down and drank the whole thing including the leaves this was 20+ years ago when i was doing intermittent fasting at the time and i was in the shape of my life with 8% bodyfat

Matcha is a minimally processed green tea, so likely in my opinion. The compounds aren't that different, but maybe run a literature search on compound difference vs green tea (such as sencha) and look for any matcha specific studies.

That could be true, i.e. heated water rather than non-heated potentially impacting health

Not sure, those are all the teas listed in the paper

Good question.

Tea is popular in many countries and not specifically in Muslim countries.

Thanks @seekfactsnotfiction9056, not yet-so many videos to make, so little time!

@@conqueragingordietrying1797 Thanks Mike for your great and hard work! You’re indeed the only channel I enjoy and take it seriously for your transparent results of everything you do! I can’t you enough! God bless you!

How can you be sure that it's the theanine? It might be if it's the only active compound that exists in all the teas mentioned but you miss out on a lot of good stuff skipping the full spectrum tea. EGCG from green tea e.g.

@@johnnielsen5493 Self testing is the only way to know

tea derives from camellia sinensis plant, the different phytochemicals present in tea depend the way the plant is processed. black tea is oxidized provides theaflavins and thearubigans iirc, while green is not oxidized providing EGCG for example. however given it is from the same plant, their effects may still be the same, perhaps green is better than black etc

That's a fair point with these studies as Mike mentioned. It would be great to know what the main compounds in say green tea and black tea are doing both separately and as a cuppa.

Yes, nobody's claiming causation.

Is EGCG a major factor?
