====== Green tea ======

A 2006 study, published in the //Journal of the American Medical Association//, found that :

>Green tea consumption is associated with reduced mortality due to all causes and due to cardiovascular disease but not with reduced mortality due to cancer."  \\ \\ [[http://jamanetwork.com/journals/jama/fullarticle/203337|Source]] {{:oa_padlock_grn.png?16&nolink|Open Access}}

Another, published in //Arteriosclerosis, Thrombosis, and Vascular Biology// (2010) claimed :

>High tea consumption is associated with a reduced risk of CHD [Coronary Heart Disease] mortality. Our results suggest a slight risk reduction for CHD mortality with moderate coffee consumption and strengthen the evidence on the lower risk of CHD with coffee and tea consumption."\\ \\ [[http://atvb.ahajournals.org/content/30/8/1665|Source]] {{:oa_padlock_grn.png?16&nolink|Open Access}}

Neither study was able to pinpoint the active ingredients that would lead to such effects.

Research from //Charité Universitäts//, Berlin, examined the hypothesis that tea might help alleviate cardiovascular problems by acting as a vaso-dilator (i.e. a blood vessel relaxant). But no firm results were able to pinpoint which chemical components were leading to tea's apparent benefits.
