Green Tea Increases Life Expectancy: Why the Japanese Live Longer
Study: A National Cohort study monitored 40,000 participants between the ages of 40 to 79. These participants were free of heart disease, cancer, and stroke. Participant monitoring and data were collected for a period of 11 years. The primary collection of data monitored green tea consumption and cause of death. The majority of the participants drank about 5 cups of green tea on a daily basis.
- The participants who consumed the highest amount of green tea, daily, were less likely to have died from cancer, stroke or cardiovascular disease.
- The female participants showed greater longevity.
Green Tea and a Longer Life
Green tea has been consumed in Asia on a regular basis for many generations. The Asian population has been shown to have a longer life expectancy than their non-green-tea-drinking neighbors. There have been a variety of studies researching the health benefits of green tea. Green tea has been found to prevent:
- Cardiovascular disease
- Alzheimer's Disease
- Parkinson's Disease
All of these illnesses and diseases can greatly impact one's life expectancy.
Another added benefit of green tea is its lack of toxicity. This is to say, its regular consumption does not cause inadvertent toxins to build up and negatively affect our cells and body functions.
What is Longevity?
Longevity basically means, long life. However, when speaking about health and nutrition, it also entails good health, a strong immune system, a body free of disorders, illness, and disease. All of these elements together would provide one with a long and healthy life filled with energy, cognition, overall clarity and a genuine sense of well-being.
Interesting Findings and Facts about Green Tea
Green tea has been identified as being antiviral and antibacterial.
Green tea has been found to prevent cardiovascular death: One study suggests that regular green tea consumers (those that drink several cups a day) avoided the development of cardiovascular diseases and, therefore, prolonged their life.
Cancer: Positive outcomes in green tea studies show regular consumers of green tea have greater cancer protection than non-green tea drinkers.
- Green tea is rich in polyphenols. Polyphenols such as catechins are known to be potent antioxidants. A commonly known catechin is Epigallocatechin gallate.
- Epigallocatechin gallate (EGCG) is vital to maintaining and promoting good health.
- EGCG blocks certain cancers. Green tea contains significant levels of EGCG.
- EGCG has been found to intervene in preventing cancerous cell growths in cancers of the breast, pancreas, mouth, colon, and prostate.
The common cold and influenza: Green tea drinkers have a greater resistance to the influenza virus and the symptoms related to the common cold and the flu. This is most likely due to improved immunity.
Cholesterol: Green tea has shown positive results in reducing bad cholesterol levels.
Cardiovascular Health: The EGCG in green tea has improved cardiovascular health by positively affecting issues such as inflammation of blood vessels, factors affecting arteriosclerosis, blood flow, platelet function and improved levels of cholesterol.
Diabetes and Obesity: Patients that have been long term drinkers of green tea tend to have lower body fat, have a smaller waistline and are less susceptible to being diagnosed with metabolic syndrome. A reduction of belly fat reduces the risk of developing diabetes and insulin resistance.
Catechins and Brain Cells: Catechins (EGCG) are the antioxidants that have shown impressive outcomes in improving health and maintaining healthy functions in the brain and heart. Promising research shows the catechins in green tea may help stop the cognitive decline found in Alzheimer's. The mice that were repeatedly fed green tea had significantly better cognitive function and memory. Impressively, brain atrophy was also suppressed in the tea group. It is not clear if the catechins are the sole reason for the positive effects or if other ingredients in green tea also play a role in maintaining cognitive function.

Hi MissOlive - I love to read your hubs, as they are filled with well researched health information. Green tea is one of my favorites, and I find it very calming. Sometimes, I drink decaffeinated, and I read the way they decaffeinate it determines if nutrients disappear. It amazes me the number of illnesses that the tea helps. I need to try a green tea latte. Sharing, Blessings, Audrey

Hi Marcy, I like your approach to mixing a variety of antioxidants through different food sources. Green tea certainly has its benefits and I have enjoyed researching the clinical studies. Thank you for your comments and support. It is always nice to see you.
Marcy Goodfleisch from Planet Earth on May 27, 2013:
An excellent and well-researched hub! I am a believer in Green Tea - my doctor has encouraged me to include many antioxidants in my diet, so that's one way I get them. It also helps to 'mix' antioxidants, since they all react differently with our bodies and help tackle free radicals in different ways. Nice work!!! Voted up!!!
Marisa Hammond Olivares (author) from Texas on November 29, 2012:
Anil and Honey, yes, India is a great producer of tea. You would probably enjoy reading my chai hub; is masala chai also something you personally enjoy? I greatly appreciate you stopping by to read and comment, thank you.
Anil from Kerala on November 26, 2012:

red mermaid, you are quite welcome
red mermaid on October 25, 2012:
thankyou for your answer missolive, maybe l should consider changing to green tea.
Marisa Hammond Olivares (author) from Texas on October 25, 2012:
red mermaid, my understanding is that ordinary tea does have several of the same benefits but not as concentrated. Green tea in particular seems to have greater antioxidant value. These particular antioxidants are what provide the health benefits and help improve the foundation for longevity. Incidentally, the studies I researched were based specifically on how 'green tea' improved longevity and health. Thank you for reading, visiting and commenting.
red mermaid on October 19, 2012:
Very informative hub...does ordinary tea still have these benefits?
Marisa Hammond Olivares (author) from Texas on September 22, 2012:
Casimiro, (great username, it made me giggle, assuming it is read in spanish, my dad used to use this 'name' with a couple of his patients, he was an eye doctor, haha) Thank you so much for your wonderful compliment on this hub. You know, I've never had maté and I have always wanted to try it. Perhaps I'll do a bit of research on it. Thanks again.
Casimiro on September 20, 2012:
Great hub, concise and full of info. What do you think about maté?

Diana Grant from London on September 16, 2012:
I love tea, and even wrote a poem about it! I am aware of some of the benefits of green tea, and use it often. I like it sweetened, with a little ginger and a slice of lemon.
Marisa Hammond Olivares (author) from Texas on September 12, 2012:
Troyangeluk, thank you! I am too. I appreciate the visit.
Victoria Lynn, yes, you could use more green tea with your busy life. I do hope you get to enjoy tea more often. It is just so good for us.

Marisa Hammond Olivares (author) from Texas on September 11, 2012:
kelleyward, I try too. I prefer matcha over regular green tea. Thanks so much for all the awesome shares, votes and pin. Have a great day.
cclitgirl, that is wonderful. My local Japanese market was out of matcha and I purchased a powdered Vietnamese green tea. Although I do miss my matcha, this particular green tea was pretty good.
Cynthia Calhoun from Western NC on September 11, 2012:
This is my morning drink of choice. It's so good to know how good it is for you - and tastes so yummy, too!
kelleyward on September 11, 2012:
I try to drink Matcha green tea every day for health benefits alone. Thanks for the reminder. Voted up and shared on Pinterest. Take care, Kelley

carter06, ohhhh my daughter adds mint too. Yum! Thanks for sharing and I appreciate the votes. Cheers!
NotPC, it sure does.
breathing, I was doing some cultural studies on the consumption of tea. It appears that it is not uncommon for several members of the Asian community to drink about 5 - 7 cups a day. No wonder the longevity studies are so impressive. Glad to see you have stopped by to read and contribute to the comments.
RTalloni, you are so right. I love my hot tea in the winter and I prefer it that way. I don't drink it as often during the hot summer months. We should though. I must admit I am looking forward to those first few cold fronts.
RTalloni on September 10, 2012:
Thanks for this reminder. Why, since it's so good for us, we get out of the habit in summertime I don't know for we could make iced green tea. When the weather turns, though, a cup of hot tea hits the spot, and when it is made right, green tea is yum.
TANJIM ARAFAT SAJIB from Bangladesh on September 05, 2012:
Taking tea is now related to our daily routine. We cannot think a single day without taking tea in the morning and evening at least. Today we know that, “Green Tea” is a great discover of medical science. It has many positive things for our body. By reading your hub now, I know some important benefits of Green Tea. Thanks for sharing this kind of informative hub with us.
