The #EHJ just published a study looking at over 40,000 U.S. adults and found that those who drank #coffee exclusively in the morning (0400-1159) had a 16% lower risk of all-cause mortality and a 31% lower risk of cardiovascular disease-specific mortality compared to non-coffee drinkers.
*All-Cause Mortality*
• Lower in morning coffee drinkers vs. non-drinkers (HR 0.88, 95% CI 0.81–0.96).
• Lowest with 2–3 morning cups/day (HR 0.71, 95% CI 0.60–0.86).
• No difference in all-day drinkers vs. non-drinkers (HR 0.99, 95% CI 0.90–1.10).
*Cause-Specific Mortality*
• Lower #CVD mortality in morning drinkers (HR 0.69, 95% CI 0.55–0.87); #cancer mortality similar (HR 0.97, 95% CI 0.75–1.25).
• No difference in CVD/cancer mortality for all-day drinkers.
• Effects similar for caffeinated/decaf.
It was suggested that as drinking coffee later in the day may disrupt circadian rhythms and melatonin production, potentially increasing inflammation and blood pressure, thereby muting coffee’s health benefits in all-day coffe drinkers. However, regular, controlled morning coffee consumption could just be a marker of health-conciousness or a lower-stress life, i.e., several significant confounding variables were not addressed in the study. The study was funded by the National Heart, Lung, and Blood Institute; National Institute of Diabetes and Digestive and Kidney Disease; and National Institute of Health. I did not check to see if any of the members of these organizations, or if the Thor’s themselves, own coffee farms, roasteries, or coffee making equipment businesses, or have stock in publicly traded coffee companies.
