A new meta-analysis1, published in the American Journal of Epidemiology, has examined the dose-response associations between coffee consumption and mortality from all causes, cardiovascular disease (CVD) and all cancers. A total of 21 prospective studies were included in the analysis, with 121,915 deaths from the 997,464 participants.
The results of this study indicate that coffee consumption is inversely (i.e. favourably) associated with both CVD and all-cause mortality. A 21% risk reduction for CVD mortality was observed in participants consuming 3 cups of coffee per day, and a 16% risk reduction was observed for all-cause mortality in those consuming 4 cups per day. No association was found between coffee consumption and cancer mortality.
This new paper adds to the existing body of research on this topic2,3,4. To date, the body of scientific evidence supports a favourable relationship between moderate coffee consumption, cardiovascular health and mortality.
