Drinking Five Cups of Coffee Daily Safe for Heart Health

The American Heart Association (AHA) stated that moderate coffee consumption, defined as up to five cups daily or 400 milligrams of caffeine, is generally safe for most healthy adults and may lower the risk of heart disease, stroke, and type 2 diabetes. This conclusion is based on a review published in the journal Circulation, which analyzed evidence from large population studies and randomized clinical trials.

The review found that moderate coffee intake is linked to lower risks of coronary heart disease, stroke, heart failure, atrial fibrillation, hypertension, and type 2 diabetes. Dr. Gregory Marcus, the lead author from the University of California, San Francisco, noted that the evidence supports moderate coffee consumption for most adults.

The study indicated that those consuming two to four cups daily had the lowest overall risk of death. However, the AHA cautioned that not all coffee is equal in health effects, particularly unfiltered coffee, which can raise bad cholesterol levels.
