Nowadays, stroke and dementia have become increasingly serious global health problems, bringing heavy economic and social burdens to the world
.
According to relevant data, stroke accounts for 10% of all deaths in the world, and the number of patients suffering from dementia is expected to increase to 152 million by 2050
.
According to research estimates, 90% of strokes and 35% of dementia can be prevented
.
Therefore, it is necessary to determine the preventable risk factors for these two diseases
.
Previous studies have shown that drinking coffee and tea has many benefits, but the association between coffee and tea intake and stroke and dementia events is rarely involved
.
Recently, a research team from Tianjin Medical University has conducted related research on this.
Research has shown that drinking coffee and tea can reduce the risk of stroke and dementia
.
The final research results were titled "Consumption of coffee and tea and risk of developing stroke, dementia, and poststroke dementia: A cohort study in the UK Biobank" and published on "PLOS Medicine"
.

pmed.
1003830 This prospective cohort study included 365,682 participants from the British Biobank.
The participants were between 50 and 74 years old, of which 45.
7% were men
.
These participants were recruited between 2006 and 2010, and the researchers followed up until 2020
.
Through questionnaires, interviews, health records, physical measurements, and the provision of blood samples, the researchers obtained relevant information and data
.
After processing and analyzing relevant information, the researchers found that after adjusting for factors such as income, habits, disease, etc.
, the intake of coffee and tea has a non-linear relationship with the probability of suffering from stroke and dementia.
Drink 2-3 cups a day.
People who drink coffee or 3-5 cups of tea, or drink 4-6 cups of coffee and tea in combination have the lowest incidence of stroke or dementia
.
Compared with those who did not drink coffee and tea, those who drank 2-3 cups of coffee and 2-3 cups of tea a day had a 32% lower risk of stroke and a 28% lower risk of dementia
.
The combination of coffee and tea effectively reduces the risk of dementia after a stroke.
Drinking 3-6 cups of coffee and tea a day has the lowest risk of dementia after a stroke
.
In a specific analysis of the relationship between coffee, tea and stroke, dementia, and post-stroke dementia, the researchers found that coffee and tea, whether consumed alone or in combination, are associated with a lower risk of ischemic stroke
.
In addition, the intake of coffee and tea and a combination of the two can effectively reduce the risk of vascular dementia
.
It is worth noting that after adjusting for confounding factors, the researchers found that participants who consumed a combination of both coffee or tea at the same time had a lower risk of stroke than those who consumed coffee or tea alone
.
In summary, studies have shown that drinking coffee and tea alone or in combination can effectively reduce the risk of stroke and dementia
.
Researchers believe that coffee and tea can reduce the risk of stroke and dementia for multiple reasons
.
First of all, coffee is the main source of caffeine, and contains phenolic substances and other biologically active compounds with potential health benefits
.
Similarly, tea contains caffeine, catechin polyphenols and flavonoids.
These substances have neuroprotective effects, such as anti-oxidative stress, anti-inflammatory, inhibition of β-amyloid protein aggregation and anti-apoptosis
.
The comprehensive protective effects of the oxidants and other biological components contained in these two beverages may be related to the underlying mechanisms that reduce the risk of stroke and dementia
.
Secondly, both coffee and tea contain specific polyphenols.
The polyphenols in coffee contain hydroxycinnamic acid, and the polyphenols in tea contain catechins.
These two components are beneficial in improving endothelial function, insulin resistance and anti-inflammatory
.
Therefore, the specific polyphenols contained in coffee and tea may play a protective role in the pathogenesis of stroke and dementia
.
Third, coffee and tea can reduce the risk of cardiometabolic diseases, including type 2 diabetes, hypertension, and cardiovascular disease
.
In addition, the researchers speculate that the intake of coffee and tea may activate certain cytokines, thereby exerting a protective effect
.
Of course, as to how coffee and tea can play a role in reducing the risk of stroke and dementia, this potential mechanism needs to be further analyzed and verified through experiments
