Is there such a thing as a good addiction? You just found one: coffee
If you enjoy your coffee and feel some kind of remorse, here is the reason to not feel the guilt. According to a new study published in Circulation: Journal of the American Heart Association, drinking coffee reduces the risk of stroke in women. This study reported that women who drank 4 or more cups of coffee a day had a 20% reduced risk of stroke when compared to women who had less than 1 cup per month. Moreover, drinking 2 to 3 cups per day reduced the risk by 19% and drinking a cup 5 to 7 times a week reduced the risk by 12%.
This was an observational study, meaning that the participants were not assigned to drink coffee or not to drink coffee. The analysis was done using data on 83,076 women who participated in the Nurse’s Health Study, which recruited women with no history of stroke, heart disease, diabetes or cancer. The coffee intake was first assessed in 1980 and repeated the assessment every 2 to 4 years with follow-up until 2004, by filling out a food frequency questionnaires about their diet. Throughout these 24 years, the authors documented 2,280 strokes.
Women who never smoked and drank 4 cups or more a day was associated with a 43% reduction in stroke risk, while women who smoked and drank 4 cups or more a day was associated with only 3% reduction in stroke risk, suggesting that the benefit of coffee in nonsmokers is more significant than smokers. Interestingly, decaffeinated coffee consumption also reduces the risk of stroke in women, indicating that the reduction of stroke risk is not due to caffeine. To further confirm, women who drank tea and caffeinated soft drink did not experience the reduction in stroke risk, suggesting that other components in coffee are responsible for this beneficial effect.
The authors of the report concluded that “long-term coffee consumption was not associated with an increased risk of stroke in women. In contrast, the data suggest that coffee consumption may modestly reduce risk of stroke”. The biological mechanism still unknown, therefore further investigation is needed prior to be considered a clinical practice.
If you’re looking to lower your risk of stroke, you may utilize standard practice such as: discontinue smoke, maintain a healthy weight by implementing daily physical activity, control high blood pressure (lowering your dietary salt intake, medication), control high cholesterol (lowering fat intake), control diabetes (maintain healthy weight by lowering your dietary fat intake, increase physical activity and lowering your alcohol intake).
