With reported benefits ranging from reducing the risk of cancer and diabetes to increased metabolism and mental clarity, green tea seems like the ultimate late night infomercial snake oil product. However scientific research tends to support the anecdotal stories that green tea is truly a boon to overall health on many fronts.
Reduced Risks of Cancer
The consumption of green tea has long been prescribed in Eastern cultures for general medicinal purposes. Recent research has proved strong evidence that green tea can reduce the risk of lung, prostate, and breast cancer. Green tea is rich in catechin polyphenols and the antioxidant epigallocatechin gallate (EGCG), both of which have been shown in clinical studies to have cancer fighting properties.
A recent study was conducted by the U.S. National Cancer Institute that showed animals on a diet supplemented with catechin polyphenols experienced a reduction in the number and size of tumors. The catechin was observed to inactivate oxidants before cell damage occurred, thus reducing the effects of the cancerous tumors. Another study conducted at Kyushu University in Japan demonstrated that growth of human lung cancer was significantly reduced by the consumption of EGCG.
Increases Metabolic Rate
Clinical trials conducted by the University of Geneva in Switzerland indicated that green tea raises metabolic rates and speeds up fat oxidation. The researchers found that men who were given a combination of caffeine and green tea extract consistently burned more calories than those given only caffeine or a placebo. Another recent study in the American Journal of Clinical Nutrition examined the effects of green tea consumption versus a placebo on weight loss and several measures of body fat in men over a 12 week period of time. After 12 weeks the men consuming green tea containing 690 mg catechins/day had a two-fold greater weight loss (-2.4 vs -1.3 kg) and fat loss (-1.4 vs -0.7 kg) compared to the men taking the placebo.
Additionally, the study assessed both subcutaneous and visceral fat in the abdominal region using computed tomography imaging. The men taking green tea had a dramatic four-fold greater reduction in subcutaneous and visceral fat in the abdomen.
With all of the evidence of the various health benefits of green tea it begs the question, why isn't everyone drinking green tea or taking green tea extract supplements?

Green Tea Cures Everything?
Not quite everything but several new studies have revealed a connection between the consumption of green tea and/or supplements containing EGCG with reducing the risk for contracting diabetes, slowing the spread of HIV, boosting the immune system, lowering stress levels and cognitive impairment, and even increasing metabolism.
A study conducted at the University of Sheffield in England discovered that EGCG boosted the immune system of HIV patients and slowed down the spread of HIV through the body. EGCG essentially won a battle for space on gp120 binding sites with HIV; preventing HIV from bonding with the cells and thus inhibiting it from spreading through the body.

Green Tea for Everyone
With all of the evidence of the various health benefits of green tea it begs the question, why isn't everyone drinking green tea or taking green tea extract supplements? Of course if you have pre-existing heart or allergy issues consult your doctor before changing your diet or taking a new supplement. But for everyone else I highly recommend adding green tea or green tea supplements to your daily diet.

Thanks FlourishAnyway, green tea is quite tasty and offers many health benefits. In past I use to drink about 2-3 cups of coffee per day but, after a thorough evaluation of my diet, I changed a few things one of them being my favorite daily hot drink, and since switching over to green tea I must say my energy level is much more stable throughout the day. - Thanks again for commenting.
FlourishAnyway from USA on November 25, 2013:
I've never tried green tea but after learning of the benefits here, I definitely want to give it a try. Thanks for presenting the information.
Linda Crampton from British Columbia, Canada on November 10, 2013:
I enjoy drinking green tea. Its health benefits are an added bonus! Thanks for sharing the interesting information, TotalHealth.
TotalHealth (author) from Hermosa Beach, CA on June 26, 2012:
Glad to hear it Angela. Do you drink green tea or take supplements?
Angela Brummer from Lincoln, Nebraska on June 22, 2012:
Green tea does do alot for my energy level.
TotalHealth (author) from Hermosa Beach, CA on May 21, 2012:
Hi @beingwell and @sweetie, thanks for the comments. I hope you do drink and/or supplement with green tea everyday. The health benefits are pretty well documented at this point so if you like the taste then drink up. If you don't like the teast then supplement :) Either way you are better off in the long term.
sweetie1 from India on May 17, 2012:
Green tea is no doubt very rich in anti oxidants which are helpful in prevention of cancer and also have lots of other health benefits. I don't know that despite knowing all this and having green tea in home we hardly drink it. But from now on we would start using it more.
beingwell from Bangkok on May 16, 2012:
We have green tea at home. I love the taste. Thanks for sharing its benefits.
TotalHealth (author) from Hermosa Beach, CA on May 15, 2012:
Hi Neil, thanks for commenting and offering a recommendation. Your description of the "leaves unfold[ing] when steeped" peeked my interest. I will definitely give Uncle Lee a try it! Thanks again.
Neil Sperling from Port Dover Ontario Canada on May 10, 2012:
Wow - I knew green tea was good for you - but your hub is very informative.... now I see it it GREAT for you.
I love green tea - I buy the bulk type called gun power from Uncle Lee... the leaves unfold when steeped and oh my VERY tasty too!
Thanks for the informative hub.
TotalHealth (author) from Hermosa Beach, CA on April 28, 2012:
Thanks for the comment, Talullah. Both products are very good by themselves or with a snack. I enjoyed green tea in the morning or at lunch, and then prefer a cup of jasmine tea in the evening.
Talullah from SW France on April 24, 2012:
Great hub! I shall see if I can find matcha in my area, and give it a go. I've never tried powdered green tea!
TotalHealth (author) from Hermosa Beach, CA on April 23, 2012:
Hi missolive, thanks for your comment. Please feel free to link to this hub, and I would appreciate the same opportunity with your article about matcha. A friend of mine you practices Aikido, a Japanese martial art, introduced me to matcha years ago. It's delicious, especially when served with a sweet treat.
Marisa Hammond Olivares from Texas on April 21, 2012:
TotalHealth - Hi there. Your title is the exact same question my daughter and I have been asking ourselves for a while now. The health benefits of green tea are exceptional and I personally think they are highly under rated. I try to have green tea and/or matcha every day. I literally feel better after I do and I don't think it is just a placebo effect. I've done quite a bit of research on it and I concur with your statements. By the way, I wrote a hub on matcha (powdered green tea) and I'd like to link it to this hub. :)

Wow! Good to know.
TotalHealth (author) from Hermosa Beach, CA on April 10, 2012:
Supplements are great even for those that enjoy tea because they're so easy to take. No matter where you're eating you can always take a green tea capsule to help bump your metabolism and take advantage of the anti-oxidants :)
Rebecca Mealey from Northeastern Georgia, USA on April 09, 2012:
Hmmm. Thanks for the reminder. I have tried to drink green tea before but I just don't like the taste. Maybe I will get the supplements!
TotalHealth (author) from Hermosa Beach, CA on April 06, 2012:
I guess I was lucky. I enjoyed the taste of green tea the first time I tried a hot cup with my sushi.
That said I have a lot of friends just like you that took awhile to warm up to the flavor but once they did they not only enjoyed the health benefits but also the flavor of the tea.
Aurelio Locsin from Orange County, CA on April 01, 2012:
I think green tea is not the tastiest drink on the planet, but it's taste grows on you. I prefer mine without any additives at all. Voting this Up and Interesting.
TotalHealth (author) from Hermosa Beach, CA on March 31, 2012:
Thanks Robie2! And I totally understand your point about coffee.
ani on March 29, 2012:
green tea stoped working for me...... it used 2 reduce my acne no lipton and all other brands have changed their taste now it dosent work for me.....
Roberta Kyle from Central New Jersey on March 29, 2012:
I love green tea and drink several cups every day-- usually in the afternoon. In summer I like it iced. I still want my cup of coffee in the morning though-- but after that, during the day, it is green tea all the way. Voting this up up up
TotalHealth (author) from Hermosa Beach, CA on March 15, 2012:
Thanks so much! I understand, at first I wasn't into either but eventually grew to love the taste!! Much healthier than coffee.
Stacy Harris from Hemet, Ca on March 14, 2012:
That is some great information on Green Tea. I have never been much of a tea drinker - however I might have to give it another try!
SaraPalmer on May 29, 2011:
I agree with your statements. I also agree that green tea supplements can address several health risk issues. Green tea drink and extracts are very affordable yet many are still unaware of the health benefits it provides. Thanks for this informative material.
David on August 09, 2010:
I used to have trouble drinking tea without sugar. Bitter taste never sat well with my sensitive tongue. Though one day I started putting lemon peels into my green tea with some of the juice, to which my mum suggested I could also try eating the lemon as well to lose more weight. Apparently after awhile, all those lemons made me acquire a taste for green tea without anything.
Linda J Smith from Google on April 23, 2010:
Yes, Why aren't thay? I have been a personal trainer and have adegree in health and exercise and I clearly know and have seen the benefits in my clients!
TotalHealth (author) from Hermosa Beach, CA on July 23, 2009:
Good point Universal Laws. If you can't tolerate caffeine then the benefits of green tea seem to be lowered but there are de-caf versions that will still offer some benefits.
Linda Joslin from UNIVERSE on July 16, 2009:
Hi, great hub on green tea, but I am responding to the title of "Why isn't everyone drinking green tea?" If you don't require caffeine in your system then it is very difficult to even contemplate drinking green tea. It is a wonderful detox tea but also has large amounts of caffeine. I can sometimes take one cup in the morning if I feel like I need a bit of stimulation but taking it anymore for me, working as a sensitive and intuitive would be counter productive and would be for anyone whos energy levels keep up high on their own accord.
TravelMonkey from United Kingdom on July 14, 2009:
I love Green tea, lots of people dislike the taste but I don't think it tastes of much at all really. The health benefits alone are worth putting up with the taste if you don't like it. I aim to drink around 4 mugs a day :)
Lilianah on July 02, 2009:
The benefits we have all heard on this forum so far. But how to drink the green tea to get the best benefit from it? I heard (or read somewhere) about not drinking it WITH/DURING meal times as (read/heard somewhere) that it neautralises some of the minerals or vaitamins (especially iron) we get from our meals. Can anyone confirm this?
Organic Tea on March 18, 2009:
This is the list of benefits of green tea which I've found during my research.
It is used to treat multiple sclerosis. It is used for treatment and prevention of cancer. It is used to stop Alzheimer's and Parkinson's diseases. It is used to raise the metabolism and increase fat oxidation. It reduces the risk of heart diseases and heart attacks by reducing the risk of trombosis. It reduces the risk of esophageal cancer.Drinking green tea inhibits the growth of certain cancer cells, reduces the level of cholesterol in blood, improves the ratio of good cholesterol to bad cholesterol. It is used to treat rheumatoid arthritis and cardiovascular diseasesIt is used to treat impaired immune function. . Some researches show that, drinking green tea regularly may help prevent tooth decay by killing the bacteria which causes the dental plaque.
ikerbill on February 25, 2009:
I drink Green Tea from Costco, Oolong Tea, Wu Yi tea and they all taste good and are good for you.
yourdietanalysis from Denver, CO on February 22, 2009:
For those of you who don't like the taste of green tea, there are other ways of getting a healthy dosage of green tea through pills and patches. Obviously, you would have to be pretty serious about green tea to where a patch. But taking a green tea pill with your vitamin in the morning is a piece of cake. And you won't taste it.
sheila R. on November 19, 2008:
Thanks for posting about green tea. I drink green tea twice a day about 3 to 4 days a week. The natural taste of it served hot. Goes really well with a nice bowl of maple brown sugar oatmeal or any hot oats cereal! My children like it with sugar. But atleast I can get some of the benefits in them also.
Female on August 12, 2008:
I am 118 years old. The cause of my longetivity is Green Tea. I drink Green tea every day and more than 3 times a day. I am turning 119 in three green days. I am going to live forever by just drinking green tea.
Lou Purplefairy from Southwest UK on June 09, 2008:
i swapped from the standard british cuppa (black tea with milk) to green tea with jasmine about 3 years ago. I cannot drink tea with milk in any more now as it just tastes to heavy. For those who don't like green tea on its own, add some ginger to it, or try some jasmine green tea pearls which have a beautiful and delicate flavour. For those who like their tea to look pretty as well as taste pretty, try a flowering artisan tea. These specially crafted tea balls "blossom" in the pot creating a wonderful visual display to feast your eyes as well as your taste buds.
these people do some lovely teas online http://www.giftsoftheorient.co.uk/chinese-quality-...
Lainie Petersen from Chicago on June 01, 2008:
Many a pot of green tea has been ruined by pouring boiling water over it, which releases bitter notes. Unlike black tea, green tea should be prepared with hot (about 180 degrees fahrenheit) water. Heat the water until it is steaming (not boiling), and then brew your green tea.
There are also several flavored green teas that mask "grassiness": Visit some tea shops in your area and ask the owners for recommendations. I particularly enjoy a ginger/lemon green tea that is available at one of my local tea shops.
If you still find that you can't stand green tea, try white tea. Very delicate flavor and also very high in antioxidants.
ant on April 20, 2008:
I started drinking tea to help burn more calories so I can lose weight. It tasted really bad at first but now I am used to it. I like it hot and sometimes with lemon and honey. I'm concerned about the fluoride issue that someone mentioned. I found this article http://www.sixwise.com/newsletters/05/02/22/why_gr... about it and its really scary. HELP!
Susan Keeping from Kitchener, Ontario on March 13, 2008:
I drink green tea every day.
Vegan Raw Diet on March 03, 2008:
Great details about green tea! I've met and worked with many that have seen benefits, but personally can't drink it (and any other tea) without getting light headed and dizzy. Several years ago I decided to transition to a raw vegan diet and got all of the same benefits I was looking for in green tea (and more).
I've noticed that many people drink green tea for the benefits, but don't change their lifestyle or eating habits. It's like eating a breakfast of fresh organic fruits then grabbing a Big Mac for lunch :). So the benefits don't really make a marked difference if you're still eating poorly or not staying active and drinking green tea regularly. It will help some I'm sure, but to get overall true health benefits a lifestyle change is necessary. For me (and many others) the raw vegan lifestyle has changed my life.
Thanks for the resource and all the best!
health-care-4life on February 25, 2008:
Excellent stuff about green tea,perhaps between us on this page and throughout the Net we can help others to a life without health issues and pain.
Incidentally another means of achieving optimum health and generally unknown to most,is GOD's Gift of Medicine;our very adult stem cells,created for all beings composed of blood and bone;including homo-sapiens.......truoble is folks prefer to rely on man-made medicines instead of trusting in GOD our Maker
And now that there's an all natural 'stem cell enhancer' available even older folks can enjoy-perfect-health or those in poor health such as heart disease,cancer or quadraplegic's are able to move upper and lower limbs.......
Please spread the good news around to those you know and love,your GOD will bless you for it;as will your friends
At 76 years I'm passionate about sharing such knowledge with all of human kind
so that they too can know a life without pain and constant medication.
Yours in optimum health
fakonig from Cape Town on February 25, 2008:
Green tea is so beneficial for you, fantastic anti-oxidant. Very true about the water quality. As far as possible only use pure/spring water.
The fluoride and chlorine in water is also very bad for your heart.
So drink more pure water and green tea and you'll go a long way to better health.
PCaholicDotCom from USA on February 21, 2008:
Fantastic hub! My wife is a big tea drinker.. I like it too but admit I don't drink it as much as I should. I prefer "brewing" over tea bags for sure... just doesn't taste the same to me.
Around 1999 we visited a tea garden in CT.. I think it was in Higganum (hope I spelled that right!) and it was beautiful! We even got to sit and sample different teas...
Originplus from New York on February 20, 2008:
This is a great article on Green Tea. Here in NYC you have to really look around to get good Green Tea, I think Japan has great Green Tea. Very informative article.
The PooP Doc on February 20, 2008:
I have been usung Green Tea for the past ten years. I make a pot of Green Tea and put it in a my frige to chill. I use two cups in my protein shake every morning. I also add some orange and apple slices to it for a refreshing iced tea drink.
This is great information about Green Tea.
make moneyonline on February 20, 2008:
Every time I read great info like this, I want to run off and make a pot of green tea.
Very useful to have all this on one page. I had never heard of gp120, and now I know a little more.
ajcor from NSW. Australia on February 19, 2008:
Thanks for that article - I was drinking green tea as recommended by our weight loss people - but got sick of it and started to alternate it with fruit teas ( more delicious) -however I was told no go get rid of the fruit teas it if I wished to lose weight as they have a natural sugar in them - fructose I guess - get back on to the green tea and enjoy the benefits of the anti-oxidisation.

Wonderful article. I have not tried the type of Green tea shown here anyway. I take Danshen tea, a chinese kind of food supplement. Thanks a lot for sharing the article.
rogue nestling on February 18, 2008:
I find green tea a little lacking, so I often use an earl grey green tea. Green tea is light enough, though to make a wonderfully refreshing iced tea, if you add a splash of lemon and a a little sweetness.
Blogger Mom from Northeast, US on February 17, 2008:
I love green tea, and this info is great to have. Thanks for sharing it! =)
Kayla on February 17, 2008:
No harm done, Mike and Gwen. It was a light, fluffy comment anyway. :) And, soon after I typed it, I myself thought 'Not that I normally wander around drinking cat urine!'
Seriously, though, I should probably try a few different varieties of it myself. I've really only had whatever kind of green tea they were offering at various Japanese restaurants. And I'm sure it is MUCH healthier and cheaper than the Diet Cokes I currently drink.

Evelyn Lim from Singapore on February 16, 2008:
Thanks for the reminder about drinking green tea. I've kindof forgotten that I've got green tea bags in my cupboard. Time to put them in a prominent place!
robertino from Canadian in Dubai on February 15, 2008:
GOOD article/hub. I lived in Japan for some 3 years speak the language and familiar with the customs. Green Tea is served with every meal everywhere. However I am not sure that the green tea we get from LIPTON has same properties as the one I had in Japan. Quite frankly even the taste is different, In Japan you can find various qualities of green tea some are very expensive but have tasted some and they are worlds away from what the average consumer gets.
I am working in Dubai now and for lack of other tea I buy the LIPTON version of green tea. But to “enrich” it I mix it 50/50 with good old Canadian Club Whiskey which is harder to get here like any other drinks living in this part of the world Alcohol is only served in hotel’s bars /special licensed bars and restaurants and for home consumption you have to either apply for a home license to buy from the local liquor store or drive to the nearest Emirate/province to fill up for supplies.
Yep, Japanese know all about health. I also like their “O sashimi” (raw fish) and “O sushi” “O” is just a polite way of pronouncing words… and of course “O Sake” which is Japanese rice made liquor (about 16% alcohol only)
GREE TEA and a touch of CC (Canadian Club Rye Whiskey) have been tolled cues everything;-) But do not take their word for it. Just Try it. Warning: It will not have same effect with Irish or Scotch Whiskey;-)
violet on February 15, 2008:
Coffee has it's merits, but not as many health benefits as tea. Personally, I love green tea, unsweetened, and drink quite a bit of it. In the summer I drink it iced, by the pitcher. It also makes good sun tea. Very refreshing. As for the flouride, if you have your own well, that shouldn't be a problem. If not, you should be filtering your water anyway, so just make sure your filter gets flouride, along with the chlorine, etc.
Andrew on February 15, 2008:
Dennis- agreed. Green tea is def an acquired taste... and at first you may have to drink it with a lot of sweetener, but if you slowly decrease the amount of sugar you add to it every couple weeks you'll end up LOVING natural, pure green tea the way it was meant to be consumed.
Yes, it's healthy. But it's also delicious. And Dale, you're wrong.
"In terms of antioxidants, white tea has the most, followed by green tea, black tea and coffee."
Quoted from ABC News article: http://abcnews.go.com/GMA/Diet/story?id=2123324
Overall, tea is much better for you than coffee, and it's also recommended that you limit coffee intake to no more than 4 8- oz glasses a day, no studies have indicated anything like this as far as I know of regarding tea consumption.
Muhhamad on February 15, 2008:
Do you have no sense of humor Mike?
Dennis on February 15, 2008:
Green tea is one of those drinks or foods that are an acquired taste. When you start it doesn't taste that great, but after a while you get to like it, or at least get used to it. So buy yourself a box of teabags and work through it before giving up.
xavo on February 14, 2008:
if you buy crap tea, it will taste like crap, duh.
a well aged tea will taste sweet and fragrant.
Bwago on February 14, 2008:
If your worried about flouride use a simple activated charcoal filter.
If that's not enough, then your probably <tinfoil>.
Dale Kaup on February 14, 2008:
Coffee has far more antioxidants than green tea.
Mike on February 14, 2008:
Do you think you made a point by bashing the image of Kayla, Gwen ?
Amy on February 14, 2008:
It's easy to get around the fluoridation problem- just get a good water filter that attaches to your faucet and filters out all ions. Aquasana makes a great one.
And I think there are natural unfluoridated toothpastes- if not, you can use baking soda, which tastes lousy but does the job.
Johny on February 14, 2008:
I live in Thailand, and they have a product called OISHI Green Tea, it comes with diff flavors . The best is Honey lemon, it tastes wonderful.
Greg on February 14, 2008:
Does anyone know how white tea compares to green tea? As far as antioxidant power goes, white tea has almost three times as much as green tea, but I've heard nothing about white tea's effects on the other issues that green tea is known to help.
trent on February 14, 2008:
we get green tea leaves and put them in the bottom of a coffee pot the let it just sit and brew all day. i'll get a cup every 2 hours or so and keep refilling it as needed. as the day goes on, it gets more and more potent. i've made a pretty good mixed tea before. just add a little honey, some milk and a little bit of granulated sugar and it will taste better than sex.
Anthony on February 14, 2008:
Looks like there are <a href="http://www.curehunter.com/research/keywordSummaryD... types of Catechin</a> ("flavonoids", what a great word).
I wonder how they choose which ones to study.
It's interesting the Japanese have so many dietary advantages. Those combined with all that exercise going up and down subway stairs every morning probably contributes to their longevity.
Tochol on February 14, 2008:
Mild green teas (not fine grade, long leaf) with berry or citrus flavorings are often a great way for someone to start drinking green tea. The taste is not nearly as strong. Also, be sure not over steep the tea- that makes it very bitter. Sure the health benefits are probably a little less (less essential oils, etc.) but a much better way to drink it so that it doesn't taste like medicine (or "cat urine"). :0
Chris on February 14, 2008:
I personally think it tastes great, assuming you choose the right blend. I'm working on a box of lemon flavored green tea right now - delicious. Good point about the flouride problem, I'll have to look into that (I'm in Canada).
