Unexpectedly, drinking coffee and tea every day would have such great benefits: how much is the best drink?

New research shows that drinking coffee and tea in moderation is related to reducing the risk of stroke and dementia.

According to a new study published in November, CNN reported that drinking a cup of coffee or tea in the morning can reduce the risk of stroke and dementia.

The study involved more than 360,000 people in 10-14 years.

The research was conducted by Tianjin Medical University in Tianjin, China and published in the scientific journal PLOS Medicine.

“Our research results show that drinking coffee and tea in moderation or at the same time is associated with lowering the risk of stroke and dementia,” said the authors of the study.

According to a study published in The Lancet in 2017, 10% of deaths worldwide are caused by stroke. Dementia is a general decline in brain function, but it may appear after a stroke.

The information of the study participants came from the British Biobank, an anonymous database containing the health information of 500,000 volunteers collected in the UK from 2006 to 2020. The study surveyed participants between the ages of 50 and 74. These people self-report. Their coffee and tea consumption.

During the study period, 5,079 participants developed dementia and 10,053 experienced at least one stroke.

Studies have shown that people who drink the following amounts of tea and coffee have the lowest risk of stroke and dementia:

-2 to 3 cups of coffee per day

-3 to 5 cups of tea per day

-Mix 4 to 6 cups of tea and coffee per day

Among the three drinking patterns, the third group had the greatest risk reduction: compared with people who drank at different times, the risk of dementia was reduced by 28%, and the risk of stroke was reduced by 32%.

Lead author Dr. Lee H. Schwamm said that because participants self-reported their tea and coffee consumption, there are limitations to the accuracy of the data, and this estimate may change. .Affected by prejudice. The Chairman of the Advisory Committee of the American Stroke Association and the head of the Department of Vascular Neurology at Massachusetts General Hospital (USA) told CNN via email.

What should I do if I drink a lot of coffee?
Previous research has shown that coffee may be beneficial for brain health.

Another study conducted in 2021 using the British Biobank found that for people who have not been diagnosed with heart disease, drinking 0.5 to 3 cups of coffee a day on a regular basis can reduce the risk of heart disease. heart disease. heart disease. Compared with people who do not drink coffee, the risk of dying from heart disease, stroke and premature death from any cause.

Some studies also show that drinking three cups of coffee a day can reduce the risk of Alzheimer’s disease.

According to the British Alzheimer’s Association, caffeinated coffee can help the brain by increasing the production of the colony granule cell stimulating factor G-CSF-helping to protect and repair nerve cells.

But don’t drink as much coffee as possible. According to a study published in the Journal of Nutritional Neuroscience in June, people who drink more than 6 cups of coffee a day have a higher risk of dementia and a smaller total brain capacity.

The results of the new study may point to some of the benefits of drinking coffee and tea, but this does not necessarily mean that people should drink more coffee during the day.

“Please note that one person’s cappuccino may be another person’s espresso,” Dr. Schwam said. The number of cups of coffee or tea varies, so we should remember that most things are best eaten in moderation. ”

“Enjoy the morning coffee, if you like it, you don’t have to give up,” he concluded.
