Study: Regular tea drinkers have a lower risk of heart attack
A US study found that people who drank a cup of tea every day were less at risk of heart attack and other important cardiovascular events than non-tea drinkers.
35 percent lower risk of heart attack
People who drink a cup of tea every day have a 35 percent lower risk of heart attack and other important cardiovascular events compared to tea abstainers. This was shown in a study by researchers at the Johns Hopkins Hospital in Baltimore, Maryland. This apparently has to do with the fact that less calcium is deposited in the coronary arteries of tea drinkers.
Calcium deposits can be dangerous
It has long been known that too much calcium can be harmful.
Calcium deposits have been linked to serious conditions such as heart disease and strokes, according to US scientists.
However, even if it has been shown that cardiovascular events occurred less frequently with moderate tea drinkers, it cannot be automatically concluded that the consumption of tea is decisive for this.
"This is an observational study," said Dr. Elliott Miller, internist and medical lecturer at Johns Hopkins Hospital.
"We can not say with certainty that it was tea or simply the healthier lifestyle of tea drinkers," said the doctor, according to a report by the portal "Medical Xpress".
Researchers did not receive funds from the tea industry
More than 6,000 men and women were involved in the study, which Miller said was not funded by the tea industry. At the start of the study, all subjects were free from heart disease.
The researchers tracked study participants' records to see who had a heart attack, stroke, or chest pain, or who died of other types of heart disease within eleven years.
In addition, the limescale deposits in the blood vessels were measured over five years and previous CT scans were compared with later ones.
The study found that people who drank a cup of (black or green) tea daily were at around a third less risk of developing severe heart disease than people who did not drink tea during the study period.
In addition, tea drinkers who drank one to three cups a day showed a decrease in the calcium build-up in their arteries.
Tea drinkers may live healthier lives in general
Scientists cannot explain why tea could help. However, there have been previous studies showing that flavonoids in tea have a protective effect on the heart.
But: "It is too early to say that drinking tea leads to fewer cardiovascular events such as heart attacks and strokes," said Miller.
"But it does suggest that tea could have a protective effect, or that tea drinkers are generally healthier."
Lona Sandon of the University of Texas at Dallas said the study, which she was not involved in, had the potential for further good news for tea drinkers.
"I will continue to drink my daily iced tea," said the nutritionist. “Tea is a great low-calorie drink as long as you don't add sweeteners to it. And if it brings health benefits, then so much the better. ”(Ad)
