Green Tea lowers the risk of Heart Disease

Greek scientists have found that regularly drinking green tea can significantly reduce cardiovascular-related morbidity and mortality.

According to a study published in the European Journal of Cardiovascular Prevention and Rehabilitation, green tea improves the function of endothelial cells that line the blood vessels and prevent the progression of atherosclerosis.

A Greek study suggests that a few cups of green tea a day can help to keep heart disease away. During the study, researchers at the Athens Medical School in Greece gave 14 healthy volunteers either green tea, diluted caffeine or hot water and measured the function of endothelial cells that line the circulatory system. The measurements were taken at 30, 90 and 120 minutes after consumption of the allotted drink.

The main factor reviewed by the researchers was dilatation of the brachial artery as a result of increased blood flow. This function is associated with endothelial function and is known to be a predictor of heart disease risk.

Researchers found that dilatation of endothelium-dependent brachial artery increased by 3.9 percent in the people who consumed green tea. This facilitated the flow of blood in the arteries and reduced the pressure on the heart.

Similar effects were not seen with caffeine or hot water, the researchers led by Dr. Nikolaos Alexopoulos reported in the latest issue of European Journal of Cardiovascular Prevention and Rehabilitation.

Previous studies have shown that black tea is beneficial for the heart, but this is the first time that studies have linked green tea to cardiovascular benefits.
