Black tea consumption is increasingly linked with reduced incidence of cardiovascular events.1,2 It is the polyphenol flavonoids in black tea that are thought to be responsible for this beneficial effect.
Epidemiological studies have shown an inverse correlation between flavonoid-rich diets and cardiovascular disease.3,4 Tea accounts for a major proportion of total flavonoid intake in a number of Western countries, including the UK.5,6,7,8
