Drinking two coffees and two teas a day can reduce the risk of stroke and dementia

Drinking two coffees and two teas a day can reduce by up to a third the risk of stroke and dementia, according to the study.

  • Chinese researchers followed 500,000 Britons for a decade for the study
  • Those who drank two coffees and teas were one-third less likely to suffer strokes
  • His chances of developing dementia also fell by 28 percent, according to researchers

Drinking two cups of coffee and tea a day may reduce your risk of stroke and dementia, a study suggests.

Chinese researchers have been following 500,000 Britons for more than a decade, monitoring their health. Volunteers were also asked about their hot beverage intake.

The results showed that participants who drank two coffees and two teas a day were one-third less likely to suffer a stroke. And their chances of developing dementia were 28 percent lower.

Staying alone with coffee or tea also seemed to provide some benefit, even if adults only consumed one a day.

But the team, led by Dr. Yuan Zhang, admitted the findings may have been due to chance, insisting the clearest link was for numerous hot drinks.

They said: “Our findings suggest that moderate consumption of coffee / tea alone, or in combination, has been associated with a lower risk of stroke and dementia.”

The study was conducted by scientists at Tianjin Medical University and published in the journal PLoS Medicine.

The researchers selected participants who were between 50 and 74 years old and who joined the UK Biobank between 2006 and 2010.

Volunteers, who were questioned about their diets when they first registered, were not followed during the ten-year period to see if they were still drinking the same amount of coffee and tea.

They were also not asked if they added milk or sugar to their drinks.


Caffeine was considered safe for consumption in doses of up to 400 mg per day for the general population.

Studies suggest that it may have a variety of health benefits, including fighting liver disease and type two diabetes.

Research has even suggested that it might even help people live longer.

It is the most consumed stimulant in the world and reports indicate that it can increase daily energy expenditure by around five percent.

The researchers said combining two to four coffees daily with regular exercise would be even more effective in maintaining weight.

A 2015 study showed that just a couple of cups a day could help millions of people on a diet stay lean once they reach the desired weight.

Participants who drank coffee and tea were compared with those who did not consume hot drinks.

Independent experts warned today that the study could not show that drinking coffee or tea prevents dementia and strokes. Instead, just highlight one link.

Dr Charlotte Mills, an expert in nutritional sciences at the University of Reading, said: “There may be other factors at work.”

But she said the findings were “consistent” with other studies that delved into the benefits of drinking coffee and tea.

Many studies have previously suggested that coffee and tea could reduce the risk of dementia.

But some newspapers have warned that excessive consumption of popular drinks could increase the risk.

An Australian study published in July found that drinking more than six cups of coffee a day increased the 53 percent chance of suffering from dementia.

It’s unclear why coffee and tea can make strokes and dementia less likely.

But some experts have pointed to polyphenols in hot drinks that are also found in blueberries and cocoa, which studies show can reduce the risk of neurodegenerative diseases.

Dr Rosa Sancho, the head of research at Alzheimer’s Research UK who was also not involved, said: “Studies like this are not able to determine cause and effect.

“Although researchers have tried to control other factors that could affect a person’s risk of suffering a stroke and vascular dementia, no firm conclusions can be drawn as to whether tea or coffee cause this lower risk.

She added: “Participants only reported on tea and coffee consumption at the beginning of the study.

“There are no data on long-term habits, so it’s not clear how important the findings are for long-term brain health.”

More than 850,000 people in the UK suffer from dementia, including one in six over the age of 80, which is caused by an abnormal build-up of protein in the brain, which prevents nerve cells from functioning properly.

About 100,000 people also suffer a stroke each year, which is triggered by a blockage of a blood vessel that leaves an area without oxygen.
