Green tea: elixir of youth and beauty
Baku, August 2 (AZERTAC). There is a lot of evidence to show that drinking green tea or taking certain types of green tea supplements can significantly reduce many of the effects of aging.
Although the exact origin of tea growing is uncertain, it is said to have been initiated by a Chinese emperor over 4,500 years ago. According to the best-known tale, in 2374 B.C., Chinese Emperor Chen Nung stumbled upon the drink when some tea leaves were blown into the water he was boiling to quench his thirst and upon tasting it, was pleasantly surprised by its flavor and aroma. Tea from China, along with her silk and porcelain, began to be known the world over more than a thousand years ago and has since always been an important Chinese export.
Tea, called "cha" in Chinese has been one of the daily necessities in China since time immemorial. Countless numbers of Chinese like to have their after-meal cup of tea. As the Chinese would often say it after a big meal "let`s drink tea to "wash" the oil away from the system and ease digestion". In general, Chinese do not serve tea at meals.
Chinese tea may be classified into three categories according to the different methods by which it is processed. All of them may come from the same variety of tea plant. Depending on the process, the leaves are used to produce black tea (fermented), oolong tea (semi-fermented) or green tea (unfermented).
green tea helps to prevent memory loss, as well as boosting your memory, while coffee had no similar effect. Black tea was also helpful but only for a day, but green tea helped for up to a week. The research published in the academic journal Phytotherapy Research, showed that green tea inhibits certain enzymes, acetylcholinesterase (AChE), butyrylcholinesterase (BuChE) and beta-secretase that affect the brain. By inhibiting the activities of these enzymes, the properties in green tea help to prevent the loss of the neurotransmitter acetylcholine, as well as preventing various protein deposits which are detrimental to the brain. By helping against memory loss the properties of green tea may delay or even prevent the onset of Alzheimer`s disease and the symptoms of dementia. However you don`t have to be elderly to see the benefits of green tea on the memory! So if you are at college and want to boost your memory while studying for tests, perhaps you should ditch the coffee and switch to green tea! Yet more researchers at Tohoku University School of Public Policy, Sendai, Japan, investigated the effects of green tea on mortality rates publishing their results in JAMA, the Journal of the American Medical Association. According to this research people who drank five or more cups of green tea daily had a lower rate of mortality from all causes, including cardio-vascular disease, than people who drank less or didn`t drink green tea at all. However, their research didn`t show any significant advantage for people suffering from cancer related illnesses.
