Global research led by the University of Galway and Canada’s McMaster University in collaboration with international stroke researchers has revealed surprising links between drink choices and stroke risk. According to studies published in the Journal of Stroke and the International Journal of Stroke, regular consumption of certain beverages, such as carbonated soft drinks and fruit juices, may increase the risk of stroke.

Professor Andrew Smyth, who led the research, explained that not all fruit drinks are the same: freshly squeezed fruit juices are likely to be beneficial, while drinks with added sugar and preservatives may pose a risk. According to the research, carbonated drinks – including sugary and artificially sweetened versions – increase the risk of stroke by 22%, while the consumption of fruit drinks increases the risk of hemorrhagic stroke by 37%. Four or more cups of coffee a day also increases the risk.

In contrast, tea, especially black and green tea, reduces the risk of stroke. The researchers found that 3-4 cups of black tea a day reduces the risk of stroke by 29%, while the same amount of green tea reduces the risk of stroke by 27%.

Professor Martin O’Donnell, co-leader of the INTERSTROKE study, emphasized that although high blood pressure is the most important risk factor, a healthy lifestyle, diet and physical activity play a major role in stroke prevention.
