The effect of tea and coffee consumption on reducing the risk of stroke and dementia.

The popularity of coffee and tea is undeniable worldwide, and they are loved not only for their enjoyment value but also for their numerous health benefits. Recent research suggests that moderate coffee and tea consumption may be linked to a reduced risk of certain brain disorders, such as stroke and dementia. These beverages are not only tasty but may also provide protection against serious diseases, which is particularly significant from a public health perspective.

The scientific community is continuously examining the effects of coffee and tea on brain health. Based on the latest studies analyzing data from thousands of people over long periods, interesting results have emerged. Such research sheds new light on the health consequences of consuming different beverages, not only for coffee and tea lovers but also for professionals in the field.

The impact of coffee and tea on brain health is thus not just an intriguing scientific topic but also has implications for our daily lives. Below, we will examine in more detail how these beverages may influence the risk of stroke and dementia.

The Impact of Coffee and Tea on Stroke Risk

Several international studies have indicated that moderate coffee and tea consumption is associated with a reduced risk of stroke. One of the largest studies, which analyzed data from over 365,000 participants aged 50-74, showed that those who consumed 2-3 cups of coffee or tea daily had a 32% lower risk of stroke.

This finding is particularly noteworthy given that stroke is one of the leading causes of death worldwide. In the study, participants self-reported their daily coffee and tea consumption, allowing scientists to uncover more accurate correlations. Researchers observed that the most significant risk reduction was noted among those who consumed 2-3 cups of coffee or 3-5 cups of tea daily.

It is important to note that dementia was diagnosed in 5,079 participants during the study, while 10,053 cases of stroke occurred. The results suggest that coffee and tea may not only protect the circulatory system but also have a positive effect on brain health.

Reducing the Risk of Dementia

Dementia poses a serious public health problem globally, and research indicates that moderate coffee and tea consumption may reduce the risk of developing this disease. Those who consumed 2-3 cups of coffee or tea daily had a 28% lower likelihood of developing dementia compared to non-consumers.

Researchers, including Yuan Zhang from Tianjin Medical University, emphasized that coffee and tea can be beneficial for reducing dementia risk both separately and in combination. In other words, drinking coffee alone, as well as the combined consumption of coffee and tea, may have positive effects on the brain.

While the research findings are promising, it is important to note that the study was based on the UK Biobank database, which represents a relatively healthy population. Therefore, scientists have cautioned against generalizing the findings. Although the beneficial effects of coffee and tea seem likely, researchers stressed that clear cause-and-effect relationships cannot be drawn.

The Need for Further Research

Researchers and experts agree that the connections between tea and coffee, and stroke and dementia, require further investigation. Tara Spires-Jones, the director of the Dementia Research Institute at the University of Edinburgh, who was not involved in the study, emphasized that many questions still need to be answered to fully understand the biological connections.

Kevin McConway, emeritus professor of applied statistics, warned that the effects of coffee and tea consumption are not uniform. It was found that while moderate consumption may reduce the risk of stroke and dementia, consuming 7-8 cups of coffee daily is associated with an increased risk. This indicates that coffee and tea consumption should be moderated, and individual reactions should also be monitored.

Overall, moderate consumption of coffee and tea may offer numerous health benefits, but it is important to approach it mindfully and moderately, as excessive consumption can even have the opposite effect. Future research may help us better understand the role these beverages play in maintaining brain health.
