Most adults can safely consume up to 400 milligrams of caffeine per day, or about five cups of coffee, which may even offer cardiovascular benefits. This is according to a new statement from the American Heart Association (AHA) published in the journal Circulation.
According to experts, moderate caffeine consumption is associated with a reduced risk of heart failure, various pathologies, and stroke. However, researchers emphasize that consuming high doses of caffeine, particularly through regular intake of energy drinks, significantly increases the risk of high blood pressure and irregular heart rhythms.
The authors of the study clarify that coffee is the most widely studied source of caffeine, and its associated cardiovascular benefits may also be linked to other compounds found in the beverage. They recommend that the healthiest way to consume coffee is filtered or instant, as unfiltered varieties, such as espresso, are associated with increased levels of “bad” cholesterol in the body. Additionally, it is advised that patients refrain from adding sugar, cream, and flavored syrups to their drink.
Notably, scientists assess that despite significant progress, the impact of caffeine on health requires further study. Future research must determine precisely why individual bodies react so differently to caffeine and what specific health effects its alternative sources have.
