"Two to three cups of coffee a day"

I really like studies that affirm the health value of one of my habits. CNN:

“The results suggest that mild to moderate intake of ground, instant and decaffeinated coffee should be considered part of a healthy lifestyle,” said study author Peter Kistler, head of clinical electrophysiology research at the Baker Heart and Diabetes Institute and head of electrophysiology at Alfred Hospital in Melbourne.

Researchers found “significant reductions” in the risk for coronary heart disease, congestive heart failure and stroke for all three types of coffee. However, only ground and instant coffee with caffeine reduced the risk for an irregular heartbeat called arrhythmia. Decaffeinated coffee did not lower that risk, according to the study published Wednesday in the European Journal of Preventive Cardiology. ....

Drinking two to three cups of coffee a day was linked to the largest reduction in early death, compared to people who drank no coffee, according to the statement. Ground coffee consumption lowered the risk of death by 27%, followed by 14% for decaffeinated, and 11% for instant caffeinated coffee. ....

"Coffee lowers risk of heart problems and early death, study says, especially ground and caffeinated," CNN, Sept. 29, 2022.
