The time of day you drink a cup of coffee may lower the risk of an early death, new research suggests. The study found that people who drank coffee in the morning had a lower risk of dying from cardiovascular disease and had a lower mortality risk than all-day coffee consumers - but the research could not prove whether coffee was the sole cause.

A first-of-its-kind study found that morning coffee drinkers have a lower risk of all-cause mortality and cardiovascular disease-related death compared to those who drink coffee throughout the day or not at all.

For a healthy heart, the best breakfast is one that provides 20% to 30% of daily calorie intake, while wating either less or more may increase certain cardiometabolic risk factors in older adults.
