Benefits of Green Tea : Protects the Heart in Patients with Acute Cardiovascular Disease
In August 2006, a European study, published in the European Journal of Clinical Nutrition, found that tea is a healthier choice than almost any beverage, including pure water, because tea not only rehydrates as well as water, but provides a rich supply of polyhenols protective against heart disease.
A Japanese study published in the September 2006 issue of JAMA, suggests that the benefits of drinking green tea is lowers risk of death due to all causes, including cardiovascular disease.
In 1994, Shinichi Kuriyama, M.D., Ph.D., of the Tohoku University School of Public Policy, Sendai, Japan, and colleagues examined the association between green tea consumption and death due to all causes, cardiovascular disease (CVD), and cancer.The study followed 40,530 adults, ranging in age from 40 to 79, in northeastern Japan for up to 11 years. Within this region, 80% of the population drinks green tea with more than half consuming at least 3 cups a day. Compared with participants who consumed less than 1 cup of green tea per day, those drinking 5 or more cups a day had a significantly lower risk of death from all causes and, specifically, risk of death from CVD, with women receiving even stronger protection than men:
Benefits of Green Tea : protects against Coronary Artery Disease
In Japanese studies, green tea consumption has been found to be an independent predictor for risk of coronary artery disease. In one study, those drinking 5 or more cups of green tea each day were found to be 16% less likely to suffer from coronary artery disease. The relationship was so significant researchers concluded, "The more green tea patients consume the less likely they are to have coronary artery disease."
An elevation in the amount of free radicals in the arteries is a key event in many forms of cardiovascular disease. The latest research shows that benefits of green tea catechins i.e inhibit the enzymes involved in the production of free radicals in the endothelial lining of the arteries. The arterial endothelium is a one-cell thick lining that serves as the interface between the bloodstream and the wall of the artery where plaques can form. By protecting the endothelium from free radical damage, green tea catechins help prevent the development of cardiovascular disease.
