Tea and Your Heart
By William I. Lengeman III
Can tea be good for your heart and cardiovascular system? According to a number of studies, there is very good evidence to suggest that this might be the case.
One study about tea’s relationship to heart and cardiovascular health comes from INSERM, France’s national institute for medical research. The study discovered that older women who drank more than three cups of tea a day were less likely to have plaque in the carotid arteries in their neck. The study looked at 2,613 men and 3,984 women whose average age was 73. Carotid plaques were present in 44 percent of female non-tea-drinkers but only in 33.7 percent of those who drank at least three cups of tea a day.
Another study, by Japanese researchers, discovered that drinking at least 17 ounces of green tea every day reduced the risk of heart disease by 31 percent in women and 22 percent in men. The study was looked at more than 40,000 Japanese people aged 40 to 79. In Japan, where green tea is more common than any other type, age-adjusted mortality from heart disease and stroke is about 30 percent lower than the United States.
Research by the Institute of Child Health, in the United Kingdom, found that epigallocatechin-3-gallate (EGCG) can reduce cell death following a heart attack or stroke. Researchers also found that EGCG apparently aided in recovery of heart cells, which reduces damage to organs.
A study of various types of tea found that subjects who drank at least two cups of tea a day had a 44 percent lower death rate after heart attacks than non tea drinkers. The study looked at the tea-drinking habits of 1,900 heart attack survivors. Antioxidants in tea called flavonoids are thought to be responsible for these effects. Studies in the United States and Holland also found that drinking tea every day can reduce risk of heart attack by up to 58 percent.
