Chinese scientists have discovered that drinking 4-6 cups of tea, coffee or caffeinated drinks reduces the risk of stroke and dementia.
PLOS Medicine magazine indicates that the Chinese scientific team headed by Yuan Jang from Tianjin Medical University reached this conclusion by analyzing and studying the data of 365,682 people kept in the UK Biobank, whose ages ranged between 50 and 74 years during the years 2006-2010, and compared them with their condition. Health in 2020. Noting that all participants in the study were in good health at the beginning of the study, but 5079 of them were later diagnosed with dementia, and 10053 of them suffered at least one stroke.
The researchers compared the frequency of strokes and dementia cases with drinking caffeine-containing drinks, and it became clear to them that drinking one cup of tea or coffee per day reduces the risk of developing these diseases. Drinking 2-3 cups of tea and 2-3 cups of coffee reduces the risk of stroke by 32 percent, and dementia by 28 percent.
It also became clear to the researchers that the indicators of people who drank 3-5 cups of tea, 2-3 cups of coffee, or 4-6 cups of tea and coffee were also good. The researchers also discovered that a person who drinks coffee daily on a regular basis has a reduced risk of dementia after a stroke, especially if he drinks coffee with milk.
The researchers say, “These results showed that drinking tea and coffee in moderation, alone or together, is associated with a lower risk of stroke and dementia.”
The researchers emphasize that these are statistical results, not causal, so they do not recommend consuming caffeine to prevent stroke or dementia. In addition, this study did not involve real people, but only analyzed their indicators saved in the biobank, and they cannot guarantee the reliability of the information provided by these people.
According to them, any data that are useful in the fight against serious age-related diseases such as stroke and dementia deserve attention
