More Happy Coffee News, This Time From Massive Cohort Studies
People with a moderately increased intake of coffee—caffeinated, decaffeinated, or overall—have a significantly lower mortality risk than coffee nondrinkers, according to a pooled analysis of three large well-known cohort studies.
The inverse association between coffee intake and mortality applied not only to all-cause mortality, but mortality from cardiovascular or neurologic causes specifically. Notably in the analysis, the association was more pronounced among people who had never smoked.
Based on about 200,000 participants and 20 to 30 years of follow-up the investigation provides solid evidence for the association between coffee drinking and the risk of mortality, and the large sample size allowed to conduct analysis among never-smokers to strip out the confounding factor of smoking.
The data of the study were publicated in Circulation 2015, November 16.
