Higher coffee intake is linked to significantly lower risk for death, two large studies confirm. The benefit was found in diverse European populations, as well as across different racial/ethnic groups, researchers report in articles published online today in Annals of Internal Medicine.
Because coffee is one of the most popular drinks in the United States and worldwide, the public health effect of coffee intake could be substantial, even if the effect on an individual is small.
Despite mounting evidence for the health and mortality benefits of coffee consumption, the relationship between coffee intake and mortality in different European populations in which coffee preparation methods vary has been unclear. Similarly, data on coffee drinking among nonwhite populations were lacking.
The two new studies address those gaps.
In EPIC (European Prospective Investigation into Cancer and Nutrition), a large, prospective cohort study, Marc J. Gunter, PhD, from the International Agency for Research on Cancer, Lyon, France, and colleagues examined the association of coffee intake with all-cause and cause-speciﬁc mortality among 451,743 participants (130,662 men and 321,081 women) in 10 European countries.
"[O]ur results suggest that higher levels of coffee drinking are associated with lower risk for death from various causes, specifically digestive and circulatory diseases," the authors write.
