Tea drinking reduces the incidence of calcified plaque in the hearts arteries

The CARDIA study consists of 5115 young adults who completed clinical examinations in the years 1985-1986. They then had subsequent examinations 6 times over the next twenty years. Drinking tea but not coffee or caffeine reduced the risk of having calcified plaque in the coronary artery and slowed its progression. Tea had no effect on carotid artery thickness. The study was performed by the National Heart, Lung, and Blood Institute in Bethesda and is published in the journal Arteriosclerosis, Thrombosis, and Vascular Biology.
