People who drank several cups of coffee or tea a day for a 10-to-14-year period had the lowest risk of stroke and dementia, according to a study published Tuesday.
Researchers at Tianjin Medical University in China studied 360,000 people who drank daily either two to three cups of coffee, three to five cups of tea, or four to six cups of a combination of both. The results of the study found that these people had the lowest risk for diseases such as stroke and dementia.
Drinking coffee or tea exclusively had a lower risk for both stroke and dementia, but those who drank a combination of several cups of both performed best in the study.
This group of people had a 28% lower risk of dementia and a 32% lower risk of stroke than those who drank neither drinks, according to the study.
The information about the participants came from the UK Biobank, a database that contains anonymous health information from around 500,000 volunteers in the UK between 2006 and 2020.
The study looked at participants between the ages of 50 and 74 who kept a running journal of their coffee and tea consumption.
According to the study, 10,053 participants had at least one stroke and 5,079 participants developed dementia during the study.
Although other studies have reported health benefits from drinking coffee and tea, the study’s researchers noted that drinking the drinks and having the result were linked, not that the drinks themselves offered protection against these diseases.
Experts also said the study has its limitations because the participants self-reported their data, which could lead to personal biases in their estimates.
“We can’t impute causation, and to say‘ drinking more coffee or tea is good for your brain. ’What we can only say is that in this study, people who reported moderate drinking of coffee / tea were less likely to suffer stroke or dementia in the 10-year follow-up, “Dr. Lee H. Schwamm, president of the United States. Stroke Association Advisory Committee and chair of Vascular Neurology at Massachusetts General Hospital, told CNN.
