Coffee Reduces Mortality Risk: Prospective Cohort Evidence
Dr. Kumar’s Take
This landmark cohort analysis found that people who drink coffee tend to live longer, with lower deaths from several major causes. It is observational, so we cannot claim causation, but the pattern is consistent and aligns with other datasets and mechanisms.
Key Takeaways
- Habitual coffee intake is associated with lower all-cause mortality.
- Inverse associations extend to cardiovascular, neurologic, and metabolic causes in adjusted models.
- Signals appear in both caffeinated and decaf drinkers, implicating non-caffeine compounds.
- Lifestyle confounding is possible, but findings persist after extensive adjustment.
Actionable Tip
If you enjoy coffee and tolerate it well, 2–4 cups daily is compatible with favorable long-term outcomes. Keep added sugars minimal.
