Tea Health Drinks

Tea is a tropical and subtropical plant which is scientifically known as Camellia Sinensis. From approximately 3000 types of tea result of interbreeding, the results obtained are 3 kinds of tea process, namely green tea, oolong tea and black tea. How tea processing tea leaves by chopping and drying in the sun so that chemical changes before being dried. The treatment will cause the color of the leaves turn brown and give a taste of black tea are typical.
Green tea, the oldest type of tea, so favored mainly by Japanese and Chinese society. Here the tea leaves have a bit of cooking, heating and drying so that only green leaf color can be maintained. While oolong tea is more of a type intermediate between black tea and green tea. The three types of tea each with its own health benefits because it contains binding biochemical called polyfenol, including flavonoids. Flavonoids are a group of antioxidants that exist naturally in vegetables, fruits, and beverages such as tea and wine.
Subclass of polyphenols include flavonols, flavonoids, flavanones, anthocyanidins, catechins, and biflavan. Derivatives of catechins such as epi-cathecin (EC), epigallo-cathecin (EGC), cathecin epigallo-gallate (EGCG), and quercetin is mainly found in tea. EGCG and quercetin is a powerful anti-oxidant with a strength of up to 4-5 times higher than vitamin E and C which is also a potential antioxidant. Antioxidants are known to prevent cells from damage considering each cell damage will contribute more than 50 diseases.
Green tea contains EGCG, as well as black tea, says a biochemist. In a study by Dutch researchers say, consume 4-5 cups of black tea every day cut the risk of stroke by 70% compared with those who consumed 2 cups of tea a day or less. Other reports mention more black tea consumption is associated with low heart attack cases. John Folts, director of the Medical School, Center for Research and Prevention of Arterial Thrombosis, University of Wisconsin, USA to find the key properties of flavonoids in tea. Research results showed that flavonoids in black tea could inhibit the clotting of blood platelet cells thus preventing the blockage of blood vessels in hantung coronary disease and stroke. Another study mentioned that the fanatical tea drinkers had higher levels of cholesterol and low blood pressure, although it remains unclear whether it was directly caused by tea.
Researchers at Case Western Reserve University, Cleveland, USA to find the effect of green tea on the skin up to 90%. It turned out that tea is very effective to protect the skin from the sun can cause skin cancer. Tea also contains fluoride which is known to strengthen tooth enamel and help prevent tooth decay. In a laboratory study in Japan, researchers found that tea helps prevent the formation of dental plaque and kill bacteria cause inflammation of the gums.
Japanese study shows, tea-producing region known as the pendudukanya fanatic tea drinker, very low death rate caused by cancer. Another study, carried out cooperation between the research team Oguni and cancer research center in Beijing to study the effects of green tea extract on mice that had been given food rations carcinogenic (cancer-triggering substances.) Reportedly, the average rate of cancer in mice that received green tea extract half of the mice that did not receive green tea extract.
The researchers believe that polyphenols known as cathecin contained in green tea, helps the human body fight cancer cells. Another study conducted by Oguni and Dr. Masami Yamada of the Hamamatsu Medical Center found cathecin kill Helicobator pylori, the bacteria trigger stomach cancer.
