Green tea is rich in catechin polyphenols that can block the action of free radicals that are famous in damaging cells. Green tea extract contains epigallocatechin gallate (EGCG), a powerful antioxidant that has been found to be effective in lowering LDL cholesterol (bad cholesterol) levels; and inhibiting the abnormal formation of blood clots, the leading cause of heart attacks and stroke.
A current study in Guangxi, China, is evaluating the effects of green tea polyphenols on aflatoxins (airborne moulds that grow in oily mediums and can cause liver damage) and oxidative stress biomarkers. Oxidative stress and inflammation have been found to be possible causes of many heart, lung, blood and sleep disorders. A fall in the levels of these biomarkers has been observed in smokers who drink green tea.
