New research from a study of more than 6,200 people suggests that even one cup of tea daily can reduce the risk of some cardiac events.
When compared to people who never drank tea, daily tea consumers had lower risk of cardiac arrest, stroke, heart attack and death by other cardiovascular causes by 35%. Their coronary arteries also stayed clearer.
“We found that being a moderate tea drinker was associated with a decreased progression of major adverse cardiovascular events,” the Johns Hopkins researchers told the American Heart Association.
The study was led by Dr. Elliott Miller at Johns Hopkins Hospital. The subjects who were studied had had no previous heart disease for at least 15 years. They spent five years tracking how many calcium deposits were in their blood vessels and eleven years recording any incidents of chest pains, stroke, heart attack or death from cardiovascular disease. The effect was found for those drinking one to three cups of day.
As with so much other tea-related research, the positive effects may be linked to flavonoids.
Thus far, the study, “Association of Tea Intake with Coronary Artery Calcification and Cardiovascular Events: Results from the Multi-Ethnic Study of Atherosclerosis (MESA),” has been presented to the American Heart Association in a moderated poster presentation. It has not yet been published by a peer-reviewed journal.
