Regular consumption of coffee, both caffeinated and decaffeinated, is associated with a lower risk of total and cardiovascular mortality, suggesting it can be part of a healthy lifestyle.
Ding et al. (2015) conducted a cohort in Healthy adults (free of CVD or cancer at baseline) (n=208,501). Coffee consumption vs. Nondrinkers was evaluated on Total mortality (death from any cause) (HR 0.91, 95% CI 0.88-0.95, p=<0.001). Moderate coffee consumption (1.1 to 3 cups per day) was associated with a lower risk of total mortality compared to nondrinkers (HR 0.91, 95% CI 0.88-0.95).
