5 things you may not have known about coffee ("Do not miss" system)

The cooling weather causes many of us to drink more hot drinks during the day and this includes several cups of coffee and also tea.

Now a new study involving hundreds of thousands of participants over ten years has found that the cup of coffee or tea you drink may be associated with a lower risk of stroke and dementia.

Of the more than 360,000 participants studied over a period of 10 to 14 years, those who drank 2 to 3 cups of coffee, 3 to 5 cups of tea, or a combination of 4 to 6 cups of coffee or tea a day, had the lowest risk of stroke and dementia, according to Researchers from Tianjin Medical University, China.

"Our findings suggest that moderate consumption of coffee and tea, alone or in combination, is associated with a lower risk of stroke and dementia," the study authors said.

Participants' information came from UK Biobank, a database of anonymous health information from half a million volunteers in the UK collected between 2006 and 2020 and included participants aged 50 to 74 who self-reported their coffee and tea consumption.

According to the study, published in PLOS Medicine, during the study period 5,079 participants developed dementia and 10,053 experienced at least one stroke.

Everything in caffeine

This of course is not the first study linking drinking tea or coffee to our health condition and we have reported many of them here on the channel.

For example, a 2021 study used by the British Biobank showed that for people without a diagnosis of heart disease, regular coffee consumption of 0.5 to 3 cups of coffee a day is associated with a reduced risk of death from heart disease, stroke and early death for any reason compared to those who do not drink coffee.

Several studies have also shown that three cups of coffee a day can reduce the risk of Alzheimer's disease.

According to the British Alzheimer's Association.

Coffee containing caffeine can help the brain in several ways by increasing the production of granulocyte colonies (white blood cells) that help protect and repair nerve brain cells.

  It's the truth

Because this is a study that relies on self-reporting there are limitations to the accuracy of the data.

"We can not determine that there is causality, and say 'drinking more coffee or tea is good for your brain,'" Dr. Lee H. Schwam, chairman of the American Stroke Advisory Committee and a neurologist at the Massachusetts General Hospital, told CNN Wests.

"What we can say is that in this study, people who reported moderate coffee / tea drinking were less likely to have a stroke or dementia during the 10 years of follow-up," Schwam said.

Moderation is the name of the game

The results of the latest study may indicate some benefits of drinking coffee and tea, but that does not necessarily mean that everyone should start drinking more cups of coffee and tea during the day.

"Not all coffee drinks have the same amount of caffeine, and people value a cup of coffee or tea differently. In any case, it's worth remembering that it's best to consume most things in moderation," Schwam said.

"If you avoid caffeinated beverages, there may be a good reason for it, and there is still no evidence that there is an advantage to starting drinking coffee or tea," he added.

"For most things, moderation is the best approach. Enjoy your morning cup of coffee, and do not take down more glasses if you enjoy them," he concluded.
