Drinking regular coffee or tea is linked to a reduced risk of stroke and dementia, but the question of whether it also prevents memory loss remains controversial. Recent studies have shown that regular consumption of caffeine can reduce the risk of certain diseases, including cardiovascular disease and certain types of cancer. However, a new study has raised the question of whether tea and coffee are beneficial for the brain and health.
The study also found that the risk of poststroke dementia was significantly lower in those who drank at least two cups per day. While the risk of stroke and dementia increased with coffee and tea consumption, the associations did not reach statistical significance. The researchers noted that the association was not consistent between coffee and tea drinkers. A significant difference was noted among participants who reported drinking three to five cups of either beverage each day.
The study used data from the U.K. Biobank, an international health resource. The participants self-reported the amount of coffee and tea they consumed. The participants were followed for a decade and a half. Of the 10,053 people who developed dementia, 5,079 had a reduced risk of the disease. The researchers concluded that tea and coffee may reduce the risk of both diseases.
The study found that coffee and tea drinkers had a reduced risk of stroke and dementia. The researchers did not find a causal link between coffee and dementia, but they did find that people who drink three to five cups of both per day had the lowest risk of either disease. It was difficult to find a single study that definitively proved that the two drinks had a beneficial effect on the brain.
In conclusion, the findings suggest that moderate consumption of coffee and tea are linked to a lower risk of dementia and stroke. The study looked at more than 360,000 participants in the United Kingdom Biobank. The researchers concluded that people who drank both drinks had the lowest risk of dementia and stroke. There is no definitive link between coffee and dementia, but the results suggest that drinking both may reduce the risk of these disorders.
The study found that moderate consumption of coffee and tea reduced the risk of post-stroke dementia. The findings, however, are subject to caveats. The sample size of the study was relatively large and did not include any people with dementia. The researchers used a Cox proportional hazards model to estimate the risk of stroke for a population of the same age. The results were based on a relatively healthy population.
