Scientists have found the ability of tea to prolong life

Moderate decline in mortality among tonic drink drinkers

A new study has shown that drinking at least two cups of tea a day protects the heart and helps you live longer. However, the study did not definitively establish that it is tea that is responsible for the lower early death rate of tonic drinkers, because it cannot be ruled out that this is due to other health factors associated with tea consumption.

Tea drinkers who drink more than two cups of tea a day are likely to live longer than those who don’t drink a drop, a new study has found.

The results, published in the Annals of Internal Medicine, conclude that the positive effects do not depend on whether the tea is black, with milk, or with sugar. Also, the positive effect is not dependent on the temperature of the drink or on genetic variants that affect the rate at which people metabolize caffeine.

According to sky news, researchers from the National Institutes of Health used data from the British Biobank, according to which 85% of half a million men and women aged 40 to 69 report that they regularly drink tea. Of these, 89% said they drink black tea.

The study was conducted using a questionnaire, which was answered from 2006 to 2010, and continued for more than ten years.

Compared to non-tea drinkers, regular consumption of black tea (the most widely consumed tea in Europe) was found to be associated with a modest 9-13% reduction in mortality over 10 years among middle-aged (mostly white) people. , adults), especially in terms of cardiovascular disease.

Fernando Rodríguez Artalejo, professor of preventive medicine and public health at the Autonomous University of Madrid, described the study as “significant progress in this area,” saying most of the research was done in Asia, where green tea is most widely consumed. And the few studies conducted outside of Asia were “small in scope and inconclusive in their results.”

The professor explained that the study did not definitively establish that tea is the cause of the lower early death rate of tea drinkers, because it cannot rule out that it is due to other health factors associated with tea consumption.

Another question that remains unanswered is whether people who don’t drink tea should start doing so to improve their health.

The expert states: “Studies need to be conducted with repeated measures of tea consumption over time and compare the mortality of those who do not consume tea on a regular basis with the mortality of those who began to consume tea or increased its consumption over time, and those who drink tea for years.”

In November, The Guardian reported that drinking coffee or tea may be associated with a lower risk of stroke and dementia, according to the largest study of its kind.

Researchers at Tianjin Medical University in China found that people who drank two to three cups of coffee or three to five cups of tea a day, or four to six cups of both, had the lowest risk of stroke or dementia. And those who drank two to three cups of coffee and two to three cups of tea a day had a 32% lower risk of stroke.
