Published in the American Journal of Epidemiology in 2001, the study found that the rate of heart attack decreased by 11 percent among those who drank three cups of tea a day.Green Tea While much of the strongest research support for tea’s potential to contribute to heart health has focused on black tea, new research has shown that green tea also offers cardiovascular benefits.Tea and Cholesterol Recent studies have found that in people at risk for coronary disease, tea and its flavonoids can have a significant cholesterol lowering effect.
High cholesterol can lead to a build up of plaque in the artery walls and narrow the arteries.
Researchers from the United States Department of Agriculture found that for adults with mildly elevated levels of cholesterol, consuming five servings of black tea per day reduced “bad” LDL cholesterol by 11.1 percent and total cholesterol by 6.5 percent.
The research was published in 2003 in the Journal of Nutrition.
In another study, published in 2003 in the Archives of Internal Medicine, researchers found that green tea had a similar cholesterol lowering effect.
The study, published in the American Journal of Clinical Epidemiology in 1999, found a 44 percent reduction in the risk of heart attack among those who drank a cup of black tea or more daily compared to the non-tea drinkers.
Another Harvard study examined 1,900 people and found that those who consumed tea during the year prior to having a heart attack fared far better in the three to four years following the attack.
Using results from seven previous studies, researchers found that individuals in the top third of dietary flavonoids intake had a 20 percent lower risk of death from coronary heart disease, compared to those in the bottom third.
The other meta-analysis reviewed 17 existing population health studies, dating from 1966 to 2000, which had investigated the relationship between drinking tea and cardiovascular disease.
