While you may have heard rumors that coffee can increase your risk of heart disease, this assumption has been proven false by two studies (1, 2). Through these studies, both The American Heart Association and NMCD Journal conclude that there is no association between daily coffee consumption and coronary heart disease. Furthermore, there is even evidence to suggest that women who drink coffee regularly have a lower risk of developing heart disease. Interestingly, research from from Japan shows that coffee (as well as green tea) consumption also proved beneficial in preventing stroke in the general population. Another study discovered that drinking 5-6 cups of coffee per day is associated with a 36% lower risk of stroke and coffee in general contributes to an overall reduction of heart mortality.
