Green Tea Lowers Risk of Heart Disease

Drinking green tea rapidly improves the health of the delicate cells lining the blood vessels and helps lower one's risk of heart disease.

Researchers writing in the latest issue of the European Journal of Cardiovascular Prevention and Rehabilitation have found that people who drink green tea have better blood vessel function just 30 minutes later. Specifically, green tea improves the function of endothelial cells. Endothelial cell dysfunction plays a key role in the development of clogged arteries, a process called atherosclerosis.

There is also finding of a growing body of evidence that suggests that powerful antioxidants in green tea called flavonoids may protect the heart. Other flavonoid-rich foods include red grapes, and dark chocolate. The study authors say their results are the first to show that green tea offers a short-term improvement in the health of arteries. Black tea has previously been linked to short- and long-term improvements in endothelial function.

A trial has been conducted on this and it is found after drinking green tea, the subjects experienced significantly increased artery widening (dilation), with the highest increase noted at 30 minutes. The caffeinated beverage and hot water did not produce any significant changes in the same individuals.
