newly come studies continue to sing the praises of black and recent tea.

According to The Tea Council of the U.S.A., Americans excite more than 2.2 billion gallons of tea each year, enough to fill more than 160000 swimming lakes Our love of tea-drinking is actually a 5,000-year-old tradition, and novel research indicates that a warm lot of tea can do more than nourish your inner man -- it can prevent disease, as well.

Historical value

More than 3000 different kinds of tea (300 in China alone) are made from the same plant, the Camellia sinensis. There are three basic adumbrations of tea produced, depending onward how the leaves are processed

Black tea, the in the greatest degree popular variety in the U is made on allowing the tea leaves to tumult before drying. Oolong tea is solely partially fermented before drying, while verdant tea is not fermented at all. Fermentation encourages the oxidization of catechins (naturally occurring antioxidants) and changes them into theaflavins and thearubigin -- flavonoids which are also highly antioxidative and are responsible for the rich color and flavor of black tea.

For several years, researchers have been looking closely at the antioxidative properties of tea, particularly virid tea. To add to this, a wealth of of the present day findings has surfaced over the last brace years. In September of this year, leading researchers from around the globe gathered for the next to the first International Scientific Symposium on Tea and Human Health to current the latest data on the part tea may play in disease prevention, including its potential to obviate human cancer.

Tea and cancer

The Chinese Academy of Preventative Medicine in Beijing mode of actioned a trial study on the events of black and green tea (given orally and topically) forward subjects diagnosed with pre-cancerous oral lesions. After six month the tea-treated form into groups displayed a marked decrease in confined apartment proliferation, suggesting that tea may inhibit cancer formation (and growth) in humans.

Another inquiry that explored the cancer-inhibiting properties of tea was guarded at the Mayo Clinic earlier this year. Researchers institute that epigallocatechin-3-gallate (EGCG), one of the six catechin polyphenols isolated from recent tea, deters cell growth of human prostate cancer small rooms Numerous animal studies indicate that EGCG stops tumor progression, lowers low-density lipoprotein (LDL) cholesterol horizontals and has tremendous antioxidative capabilities.

modern research at Rutgers University, NJ has revealed that the one and the other black tea and green tea preclude the progression and spontaneous formation of lung tumors in mice.

The merit of these fresh findings has spurred new interest in the olden question of whether or not tea can really retain us healthy. Of special interest is the direct applications tea may have upon a variety of human cancers. While there is still greatly to learn, the data in such a manner far suggest that the polyphenols not absent in tea are capable of binding with cancer-inducing agents, in the same state [i]or[/i] condition as free radicals and peroxides, before they can damage healthy tissue. Studies also indicate that as little as four to five chalices of tea daily may provide enough antioxidative qualities necessary to thwart many diseases.
