| Black Tea may reduce heart disease risk: Study Business Standard
"Tea is one of the beverages richest in antioxidants called flavonoids, and the absorbed forms of tea flavonoids might protect cells and tissues against oxidative damage associated with cardiovascular disease," stated Catherine Rice-Evans, Ph.D., Professor of Biochemistry, King's College, London, during an educational symposium titled "Sipping Tea for the Heart".
Research presented at the American College of Cardiology (ACC) Annual Scientific Session suggests that drinking black tea may be good for your heart. Leading scientists presented preliminary results from three studies that add to the growing body of evidence suggesting that the antioxidants in black tea may contribute to healthy cardiovascular function.
Lenore Arab, Ph.D., Professor of Epidemiology and Nutrition, University of North Carolina School of Public Health, Chapel Hill, presented new epidemiological research that how black tea drinking may decrease the rate of heart attacks.
"We conducted a comprehensive review of 13 different studies to take a closer look at the association between tea and cardiovascular disease," said Arab. "Our findings, scheduled to be published in an upcoming issue of the American Journal of Epidemiology, suggest that the incidence rate of a myocardial infarction decreased by (an estimated) 11 per cent by drinking three cups of black tea per day."
The results of a recent study presented by Myron Gross, Ph.D., University of Minnesota, found that one of the ways black tea drinking may support cardiovascular health is by promoting healthy platelet function. Activated platelets contribute to endothelial damage and can lead to clots that cause myocardial infarction and strokes. "Based on our preliminary findings, daily consumption of black tea may help decrease platelet aggregation while increasing antioxidant concentration in the blood a double dose for your health," said Gross.
Fellow presenter Joseph A Vita, MD, Professor of Medicine, Boston University School of Medicine, discussed findings from his new study that found drinking up to four cups of black tea per day improved endothelial function in blood vessels of people diagnosed with coronary artery disease.
"Our results demonstrate that drinking tea reverses an important underlying abnormality of blood vessel function that is related to heart disease and stroke," said Vita. "The effects were visible as soon as (within) two hours of drinking the first cup."
These studies support the notion that tea drinking may play a positive role in a healthy diet. "While additional research must be done before we draw definitive conclusions, emerging findings are promising and there are still many reasons why people should include tea as part of a healthy lifestyle," said Douglas Balentine, Ph.D., leader of the Unilever Health Institute research program on the Health Benefits of Tea who chaired the symposium. "For instance, like fruits and vegetables, both black and green, hot and iced brewed tea contains natural compounds called antioxidants, which research suggests can neutralize cell-damaging free radicals."
Also presenting at the symposium was Mary Corretti, M.D., and Associate Professor of Medicine, University of Maryland School of Medicine, who discussed the protocol for a clinical trial involving tea consumption and endothelial function following a high-fat meal. Results are expected later this year.
India has now to its credit the first Tea & Health Information Center in Asia. This Center has been set up in Bangalore by Hindustan Lever Ltd., the largest Tea company in the world. The Brooke Bond Tea & Health Information Center gathers latest information on internationally proven scientific data related to Tea & Health and disseminates it to consumers and media like.
