For centuries the art of drinking and serving tea has played a major cultural role in many Asian countries. Americans are now discovering this healthful brew. Studies have shown that green tea is a powerful antioxidant that supports cardiovascular health and promotes dental health and glucose metabolism. The polyphenols are the most beneficial components in green tea, especially the catechin EGCG.
The Tale of Tea
Green, black and oolong teas are all processed from the young leaves of Camellia sinensis, a white-flowered evergreen that originated in southeastern Asia. Monks brought it to Japan and from there it spread around the world. The three basic types of tea are classified by processing method. Black tea is made by fermenting and roasting the leaves, giving it a dark color and rich taste. Oolong is partially fermented. Green tea is lightly steamed so it retains the chlorophyll of the leaf and its green color, along with high concentrations of polyphenol compounds.
The Science of Green Tea
All teas contain polyphenols, which are chemical compounds that act as antioxidants. In green tea the main polyphenols are the catechins, including gallocatechin (GC), epigallocatechin (EGC), epicatechin (EC), and epigallocatechin gallate (EGCG). Studies have shown that these catechins are the beneficial, health-promoting components of green tea, especially EGCG, a proven powerful antioxidant.
Health Benefits
Catechins have significant antioxidant power and may prove to be heart healthy agents in combating lipid peroxidation within the cell membranes that line arterial walls. Antioxidants neutralize destructive free radicals and support cardiovascular health by preventing the oxidation of cholesterol. Oxidized cholesterol is an unstable molecule that damages the integrity of arteries. Research shows that EGCG is a much more potent antioxidant than vitamin C or vitamin E.
The catechins in green tea have been shown to fight foreign organisms and help prevent the plaque buildup that leads to poor dental health. Research shows that green tea also promotes healthy glucose levels in the blood stream by enhancing the action of insulin.
