Daily Black Coffee Linked to Lower Heart Disease Risk, American Heart Association Says
A July 2026 scientific statement from the American Heart Association found that drinking two to four cups of black coffee per day is associated with a lower risk of heart disease, heart failure, and stroke. The review, published in Circulation, notes that additives like sugar and cream may cancel out the benefits. Energy drinks, by contrast, carry cardiovascular risks.
The American Heart Association released a scientific statement in July 2026 concluding that moderate consumption of black coffee is generally safe for most adults and may lower the risk of heart disease, heart failure, and stroke.
The review, titled "Caffeine and Cardiovascular Disease" and published in the journal Circulation, found that drinking two to four 8-ounce cups of black coffee per day is associated with reduced cardiovascular risk. Researchers noted that coffee contains antioxidants and anti-inflammatory compounds that may contribute to these benefits beyond caffeine alone.
The benefits apply specifically to black coffee. Adding sugar, cream, or flavored syrups can add hundreds of calories and may cancel out the cardioprotective effects. Preparation method also matters: unfiltered coffee made in a French press or by boiling contains cafestol, a compound linked to higher LDL cholesterol levels. Paper-filtered and instant coffee do not carry this risk.
The AHA cautioned that caffeine affects people differently based on genetics, age, metabolism, and existing health conditions. Drinking more than four cups per day may increase the risk of heart failure. Energy drinks and concentrated caffeine shots, which contain far more caffeine per ounce than regular coffee, are associated with high blood pressure and irregular heart rhythms even in healthy young adults.
Because of limited data, caffeine was not included in the AHA's 2026 Dietary Guidance to Improve Cardiovascular Health. Experts advise people to pay attention to how their bodies respond to caffeine and consult a doctor about appropriate intake.
