ARThe relationship between coffee consumption and heart health has been a topic of debate for years, with some studies suggesting it poses risks while others highlight potential benefits. A recent scientific statement by the American Heart Association (AHA), published in the journal Circulation, reviews available evidence and concludes that consuming up to 400 milligrams of caffeine per day—equivalent to five cups of 230 ml coffee—is safe for most adults. This level of intake may even be associated with a lower risk of heart failure, coronary disease, and stroke in certain individuals. The report emphasizes that moderate coffee consumption, without added sugars or ingredients, does not increase cardiovascular risk for the majority of adults. However, energy drinks contain significantly higher concentrations of caffeine and are linked to elevated blood pressure and irregular heartbeats, even among young adults considered low-risk. The study notes varying effects based on dosage and health indicators, such as increased hypertension risk with one to three cups daily but reduced risk for heart conditions with two to four cups. Consuming more than four cups could potentially raise the风险of
