A comprehensive overview of the inherent properties, chemical and biochemical functions, actions for lowering the risks of cardiovascular and infectious diseases and cancers, and underlying mechanisms of tea polyphenols. It reveals the bioantimutagenic potency of epigallocatechin gallate (EGCg) found in green tea.
"This book … is an update of all the recent and new research into tea. There is increasing scientific validation of the health benefits of green tea. … This book elaborates on the significance of fermentation processes in green and black teas.
