Green tea

Did you know that Green Tea is known to have extreme health benefits of which unwanted fat loss and prevention of oral cancer are primary? In this article, let us look at how having Green Tea goes about achieving this.

Oral Cancer: Pennsylvania State University’s Joshua Lambert, co-director at Centre for Plant and Mushroom Foods for Health and his research team has observed that the EGCG compound (epigallocatechin-3-gallate), a major percentage of Green Tea’s anti-oxidants, ensures that cancerous cells found in the oral cavity self-destruct. This happens as a result of mitochondrial damage enthused by EGCG.

There is no need to panic. The EGCG did not affect the healthy cells quite the same way and it actually enhanced the mitochondrial membrane potential, which enhances healthier metabolism internal to the cell.

Joshua Lambert stated in a press release – “EGCG is doing something to damage the mitochondria and that mitochondrial damage sets up a cycle causing more damage, and it spirals out, until the cell undergoes programmed cell death, it looks like EGCG causes the formation of reactive oxygen species in cancer cells, which damages the mitochondria, and the mitochondria responds by making more reactive oxygen species.” Detailed research is available at Molecular Nutrition and Food Research (online version).

The working of Green Tea’s EGCG has been attributed to a protein known as the Sirtuin 3 (SIRT3). Lambert stated – “It plays an important role in mitochondrial function and in antioxidant response in lots of tissues in the body, so the idea that EGCG might selectively affect the activity of sirtuin 3 in cancer cells – to turn it off – and in normal cells – to turn it on – is probably applicable in multiple kinds of cancers.”

Can we safely then say that Green Tea can be THE cure for all sorts of cancers, of course, post research. Indicators are that this research is progressive and we can be seeing a lot more benefits coming from EGCG. Normal cancer patients are treated with strong anti-cancer medications that have ample side-effects. Chemotherapy can be quite heart-breaking for hair follicles and intestinal cells; however Green Tea has absolutely no side-effects.

Time to start the Green Tea habit? – Four cups a day and keep cancer away.

Weight Loss: Green Tea is one of the most beneficial drinks for humans available on the planet and it comes with a host of substances that aid good health. The primary and most important ingredients of Green Tea are a wide range of anti-oxidants that help you detoxify the body without consciously aiming to do so.

Detoxification removes a lot of impurities along with the fat particles. Additionally, as discussed above the EGCG present in Green Tea enhances metabolism. Increase in metabolism also converts to fat loss to a certain extent.

Going further the EGCG actually controls the enzyme that helps in breaking down a hormone called the norepinephrine. Once this is achieved, it results in excessive norepinephrine increases. This increment signals the central nervous system which in turn forwards the signal to fat cell to break down quickly.

The percentage of caffeine in Green Tea is much lesser than that is found in normal tea or coffee (about 30%). The combination of EGCG and Caffeine also have a symbiotic effect on the human body resulting in breaking down more fat into the blood stream converting it into energy that can be used or ingested into the muscle cells, if exercised regularly.

Lesser fat has a positive effect on the body in the form of a healthy liver, better heart, lesser blood pressure and so on.

While reducing the probability of cancer, losing weight can be an icing on the cake.

When do you want to make Green Tea your favorite beverage?

So what else do we know about Green Tea?

What is Green Tea?

A simple definition is not enough to cover green tea, because product itself creates many of the definitions when you experience it. All the tea types which are distinct from flowers infusion and herbal and named as tisanes by lover of the tea, prepared from a plant relating to Magnolia trees and with botanic family name of Camellia sinensis. Though this tree can reach at maximum height of 30 feet in world, this plant keeps itself as shrub and reaches at height of 3 feet only, which helps in picking the leaves by tea drinkers and its new growth.

Its tea plants can grow in countries where weather is warm but can also flourish in areas which are ranging at height of 7,000 feet. Green teas are perfect however from those plants which are grown at a height of 3000-6000 feet, because in such climatic conditions the leaves will grow slowly along with slow maturation of plant and will yield the best flavored taste. Based on the altitude on which this plant has grown, it will take an average 2 to 5 years to get ready for leaves picking and when it starts bearing its leaves, it will remain productive for up to a century.

This tea plant produces a camellia like flower, abundant foliage along with a berry, however only the youngest leaves are taken from young buds. The new shoots are called flush, which will start growing every week starting from growth at lower altitudes first and higher ones will take more time to start growing. Its young leaves are picked by hand through tea puckers and best of it can produce 40 pounds every day, leading to tea equal to 10 pounds. All the Green tea plants belong to same species, the Camellia Sinensis, but their growth conditions are different, including their soils, climate and altitude and so leaves many be different.

The process through which they leaves are passed through, it can affect to make three predominant types of teas, the Oolong, black and green. Green tea is the product which is least processed and gives a catechin named as antioxidant polyphenols. It gives EGCG, which is the main reason for effective recovery of many diseases. We will discuss about EGCS later, but it is the main component which gives so healing effects from tea and have bundle of advantages.

Preparation of GreenTea

Green tea is prepared from steaming the harvested leaves, putting them in water and mixed sugar once water has turned to steam and heating the tea with these components before it turned the color, take it from the heat. After heating, green tea leaves will be rolled and spread out. So in end, you will get a green, astringent taste which is similar to the taste of its leaves. Green tea has always remained the popular from among all the teas imported from china, where it is believed was used thousand years ago. At that time, Chinese were the best botanists and historians and they found the taste, aroma and health benefits of green tea.

To get amazing health benefits, green tea leaves are heated with water till to the temperature where EGCD compound is preserved and not oxidized. A major difference between green tea and other teas is that; green teas preserves the taste of EGCD while other teas breaks down the healing properties of EGCG and it is taken away. Green tea has detailed history and it will be much fascinating to know about it.

The History of Green Tea

It has been found that green tea was being used in China as long as 4000 years ago. Although there is no accurate data available to know about how and when the green tea was prepared by someone and its stories are all relating to myths and not sure about their realties. Among these, one story have displayed that one of legendry person in Chinese history, Sheng Nong first discovered the green tea as health beneficiary herb in 2737 BC.  It has been told in the story that one day Sheng was boiling water under a tree and some of its leaves fell into the steam. After tasting it, he found that those leaves had miracle effects on health and power, resulted in entry of this tea in medical herbs lists.

History Of Green Tea

Initially this tea was used as medicine and also offered to guests, but it became a commonly used beverage at the times of Western Han dynasty. This tea was grown around the monasteries of Buddhists and it was started in trade during Ming Dynasty.  It was in 6th century when a Buddhist first introduced green tea in japan. In Europe, green tea was first introduced by a Portuguese missionary during the 16th century. During 1615, the English traders who were working with East India Company were aware about use of green tea and it’s quite evident that green tea spread in Europe in less than hundred years. This resulted in English tea import which increased from 100 pounds each year to 5 million pounds imported. This increasing demand established businesses for many of the exporters and voyages of shiploads with green tea were sent to Europe every month.

Among those Chinese elites and bureaucrats who have established an affluent dinning habit, green tea was their right choice and this became essential drink after the dinner in China and many of the Asian countries. When we use word “tea”, it means Green tea in United Kingdom. Decades before, green tea was prepared in steam with fresh leaves directly plucked from its trees to preserve the ingredients essential for health and get the natural taste of tea similar to its leaves.

Green tea was found to be an expensive beverage in historical China. Consumption of tea was limited only to the wealthy families and elite segments of the population. However after the fall of Mongolian rule in 1368 A.D, use of green tea was spread from wealthy families to all around the china. During 1405 to 1433, china as considered the sea power with its coverage of exports around the world, green tea was indispensable supplies used by the seamen. The amount of vitamin C which they could get from drinking of tea was enough to eliminate European sailors after hundred years and still its benefits were not known to the medical officers which were assigned for their journey to Africa from the China.

A popular painting which had the title of “Drinking Tea”, translated from a Chinese elegant title “The Tea tending event” and left for display in Palace Museum, the traditional methods of preparing tea was recorded by Tang Yin, at the time when China was ranked as most prosperous country in the world. The use of fresh leaves grown at his house near southern hillside has been described in the poem written on that painting. It tells that use of fresh leaves for green tea or non-oxidized leaves were used for preparation of this format of tea in era when Ming Dynasty was prevalent in china.

However with start of Chien-lung Dynasty in 1736, which ended in 1796, he was the man who used to drink only black tea because he came from northern minority and he wanted to display himself a commander. When he was passing by some field where green tea was planted, a servant offered him green tea, which he responded after taking few sips with “Tasteless, Too Bland”, but after few miles he travelled, he told his servant that it was the good tea he ever tasted. He found that characteristics of green tea are soothing and its taste came few minutes after taking its sips. In this way, green tea was offered to family of Manchu and became beverage of their choice.

Introduction of green tea to United States from Europe dates back to 1945, when European warriors and traders took it with themselves to the newly discovered areas of America. First Chinese restaurants which were ran by Chinese emigrants started offering the green tea to their customers in newly discovered States of America. A book written about benefits of green tea, Kissa Yojoki by a priest named Eisai in 1191, it was being told that use of tea dates back to thousand years before in Asia. Also in this book, it was explained about effects of drinking tea on our vital five body organs and refreshment we get from use of tea regularly.

Health promoting flavonoids exist in green tea in high volume, and account for 30 percent of green tea leaf when it is dry. These include anti-oxidants, catechin and derivates from these. EGCG, named as epigallocatechin-3-gallate is the catechin which is found in large quantity in green tea. Due to this catechin, green tea work as anticancer and has many effects of antioxidant. Like Vitamin C and E antioxidants, catechin is potent free and therefore acts as health supportive.

Health Benefits Of Green Tea

Health benefit of the green tea are based on its consumption, should be same like used as 3 cups per day in Asian countries. This amount of tea usage will provide 240 to 320 mg of polyphenols which is an anti-oxidant and its one cup will offer you 35 mg of EGCD. Extensive health benefits studies on green tea have been done and scientific results have encourage more people around the world to use it as well as new studies which are performed on green tea. According to Nov 2004 results from PubMed database, there were approx. 1500 research studies done on green tea and more than 420 studies were performed in that year, 2004.

Users of green tea have low risk to be exposed to many of the diseases, ranging from viral and bacterial simple infections to chronic degenerative situations like osteoporosis, periodontal, can and stroke. Current studies have focused more on how green tea can offer you more healing effects as compared to its historical usage.

According to European study of Aug, 2006, tea is the healthier beverage than any other drink, even the use of pure water. It is because tea can offer the hydrates requirements and polyphenols which protect us from many of the ailments and heart diseases. According to a Japanese study conducted during 2006, it has been found that green tea has so much power to protect us from all the causes of death. A study done by Japanese scientist in 1995 in which a population of 4000 was taken with age of 40-79 years old, research observations went for about 11 years and was performed in north east of the Japan. Based on research results, it was found that 80 percent of the users are taking green tea 3 cups every day, and users which had taken five cups of green tea per day had lower effects of disease and more resistance to it, as compared to those who took only one cup of green tea per day.

Here are some of the results for both women and men with green tea benefits for each group;

In Women

  • In women, those taking green tea have 23 percent low risk for death from any cause
  • There is only 31 percent risk in women to dye from CVD if they take green tea
  • There is 62 percent lower risk of death in women from stroke if they take green tea

Although no positive effects to prevent from cancer were found by this study done, there are many other researches performed during 2006 in which green tea has been suggested due to its anti-cancer effects. In this study women were compared for breast cancer prevention, and it was found that women who take green tea have 22 percent lower chances to develop breast cancer in them. In many studies, the health promoting effects are often complicated to understand because people adopt the healthy lifestyle with normal habits for health and so in studies it was also mentioned that since green tea has health benefits, people in japan may be using this beverage as primary source for their health maintenance. It is also not possible that significant drop down in deaths due to healthy diets may result in learning the health consciousness.

In this study, researchers told “patients who take more green tea, they will never have any problem to suffer from coronary artery disease”.

Green tea lowers the LDL cholesterol, lipid peroxides and triglycerides to lower the risks of atherosclerosis and improve LDL being bad to HDL being good. Similar research study was performed on animals and it was found that animals which took lower dose of green tea had 46 percent more chances to suffer from atherosclerosis.


Green tea is much beneficial to lower down the cholesterol and raises it as HDL being good. Similar work study performed on human beings found that people who were taking green tea regularly had lower cholesterol level as HDL. Green tea has polyphenols which block the intestinal absorption of cholesterol and it decreased the blood levels of LDL which were harmful in male smokers. High consumption of green tea, estimated 8-10 cups per day will result in higher HDL and lower LDL to drop down the level of cholesterol and provide them best fitness and healthier all their life.

Green tea also lowers down the intestinal fat absorption and it has good fat loss properties in human beings.
