The world's most popular beverage has long been a subject of debate.
The American Heart Association has released a comprehensive review of data on the effects of coffee on the cardiovascular system. For most healthy adults, up to five cups a day do not pose an additional risk to the heart. The study was published in the journal Circulation.
Coffee is one of the most popular beverages in the world, but its effect on the heart has long been a subject of debate. Early studies reported short-term increases in heart rate and blood pressure after coffee consumption, raising concerns about the risk of arrhythmia and heart attack. Later large-scale studies yielded conflicting results.
The current review covered data from hundreds of clinical and epidemiological studies conducted over the past few decades. The authors assessed the association between coffee consumption and the risk of heart attack, stroke, heart failure, atrial fibrillation, and sudden cardiac death.
It turned out that moderate coffee consumption—one to five cups a day—does not increase the risk of cardiovascular events in most people and may be associated with a slight protective effect. This benefit is attributed to the antioxidants and anti-inflammatory compounds in coffee, which reduce chronic inflammation—one of the key risk factors for heart disease.
Cardiologists note some exceptions. Pregnant women are advised to limit their intake to one or two cups. People diagnosed with arrhythmia or unstable blood pressure should discuss their intake with a doctor on an individual basis. It’s also important to consider additives: coffee with large amounts of sugar and cream negates any potential benefits due to excess calories and saturated fats.
