Coffee consumption and stroke
Recent research shows that moderate coffee consumption may reduce the risk of stroke.

A study of 26,556 male Finnish smokers recently found that the risk of developing a non-hemorrhagic stroke fell by 12% with the consumption of 4-5 cups of coffee per day. The risk was reduced further to 23% in the heaviest consumers (6 or more cups a day) compared to those who dank less than two cups a day.

Similarly, a study of 34,670 women has shown that coffee consumption (2-5 cups a day) was linked to a 22-25% reduced risk of total stroke, cerebral infarction, and subarachnoid hemorrhage but not intra-cerebral hemorrhage.

The Nurses’ Health Study also reported that women who drank 2-4 cups of coffee a day were 20% less likely to experience a stroke than those who drank one cup a month. Other drinks containing caffeine, such as tea and caffeinated soft drinks, were not linked to risk of stroke.

Finally, a recent meta-analysis of 11 studies, including 10,003 cases of stroke among 479,689 participants, identified that moderate coffee consumption may be weakly linked to a reduced risk of stroke.

In conclusion, the lifelong, regular and moderate consumption of coffee/caffeine (the equivalent of 3-4 regular cups of caffeinated coffee) appears to have a positive effect on our cognitive abilities. It may safeguard our cognitive potential as we age, have preventative effects on the development of neurodegenerative diseases such as Alzheimer’s and Parkinson’s, and reduce the risk of stroke. However, additional research is needed before any firm conclusions can be drawn.
