Research: Drinking 3 cups of tea per week helps you live healthier and increase longevity

Legend has it that, in 2737 BC, Emperor Deity, also known as Shennong, traveled widely throughout the world. He tasted hundreds of herbs, so he was hit by up to 72 kinds of poison.

One day, when Shennong sat under a tea tree, the attendant was boiling water, when some tea leaves fell into the kettle. He tasted the water and immediately was detoxified. Thanks to the blue sky, Shennong began to pass on this drink to posterity.

While the story is just a legend, more and more scientific research supports the health benefits of leaves Camellia sinesis, Scientific name of tea leaves. Most recently, a study in the European Journal of Preventive Cardiology found that people who drank tea three times a week or more frequently had longer lifespans and better health.

Legend has it that in 2737 BC, Emperor Dei, or Shen Nong, was the first to try the tea-made water.

The study was conducted by the Chinese Academy of Medical Sciences to investigate the association between tea drinking habits and the risk of atherosclerosis as well as the risk of death from all causes. In particular, they recruited 100,902 participants. These people have no history of heart attack, cancer or stroke.

Participating volunteers are divided into two groups: those who have “habit“drinking tea, defined as drinking tea more than 3 times per week and those”no habit“drinking tea, defined as when they drink tea below that frequency.

Participants’ health was then monitored for an average of 7.3 years. Along with that were the demographic data collection, blood samples, risk factors in lifestyle, medical history and the maintenance of their tea drinking habits.

During the follow-up, the scientists counted 3,683 cardiovascular events related to atherosclerosis, 1,477 deaths from the disease, out of a total of 5,479 deaths from all other causes. .

From the collected data, the researchers processed and were able to conclude that regular tea drinkers had a 20% lower risk of heart disease and stroke, heart disease risk and stroke is 22% lower and 15% lower risk of death from all causes compared to others.

The data also showed that middle-aged people over the age of 50 who regularly drank tea were able to fight coronary heart disease and stroke, on average 1.41 years later than those who drank less tea. The cups of tea also helped them to average 1.26 years of life expectancy.

Tea drinkers regularly will be able to fight coronary heart disease and stroke, onset 1.41 years later on average and live longer than average 1.26 years.

Unsurprisingly, the benefits of tea leaves have continuously stirred the scientific community for many years. Researchers have found that polyphenols and other metabolites in the leaves of Camellia sinesis can reduce the risk of developing many diseases including arthritis, cardiovascular disease and even cancer.

“The health protective effects of tea are most evident in the group that maintains the habit of drinking tea continuously“, The lead author of the new study, Dongfeng Gu from the Chinese Academy of Medical Sciences, said.

Studies on the defense mechanism show that the main bioactive compounds in tea, namely polyphenols, cannot be stored long-term in the body. Therefore, in order to protect the heart in the long run, people need to drink tea regularly”.

And among the teas included in the study, scientists say green tea is the drink with the greatest health benefits. A sub-analysis of the study results showed that drinking green tea was associated with a 25% lower risk of heart disease, stroke, stroke due to heart disease and death from all causes. Meanwhile, the health effects of black tea are negligible.

In our study set, 49% people drank green tea regularly, while only 8% liked black tea. A small percentage of people who have a habit of drinking black tea have a habit that makes it difficult to benefit from it, but our findings suggest that different teas affect health at different levels. different degrees“.

The explanation may be from the fact that green tea contains more polyphenols than other teas. Black tea, unlike green tea, is fully fermented, causing the polyphenols to oxidize and lose the antioxidant effects of the tea leaves.

Moreover, black tea is often used as a raw material for making milk tea, with the sugar content of this drink, the health effects have been overshadowed by the harmful effects of the sweetness in it.

Green tea contains more polyphenols than black tea.

In addition, research also shows that there is a difference in tea drinking habits between men and women. 48% of men in this study had a habit of drinking tea more than 3 times per week, compared to only 20% of women.

However, women are the ones who benefit more from tea. They have a much lower incidence of heart disease and stroke as well as a lower risk of death from these conditions.

Xinyan Wang, a research co-author from the Chinese Academy of Medical Sciences, said the research is continuing to collect data from more women. From there, scientists hope to be able to assess the impact of tea drinking habits on their health more clearly.

The new study is published in the European Journal of Preventive Cardiology, a journal of the European Heart Association.
