One study surveyed more than 520,000 people in 10 European countries, making it the largest study to date on coffee and mortality, and found that drinking more coffee could significantly lower a person’s risk of mortality.
These findings are consistent with previous studies that had looked at majority white populations, said Veronica Wendy Setiawan, associate professor of preventative medicine at USC’s Keck School of Medicine, who led the study on nonwhite populations.
The new study shows that there is a stronger biological possibility for the relationship between coffee and longevity and found that mortality was inversely related to coffee consumption for heart disease, cancer, respiratory disease, stroke, diabetes and kidney disease.
“We looked at multiple countries across Europe, where the way the population drinks coffee and prepares coffee is quite different,” said Marc Gunter, reader in cancer epidemiology and prevention at Imperial College’s School of Public Health in the UK, who co-authored the European study.
“The takeaway message would be that drinking a couple cups of coffee a day doesn’t do you any harm, and actually, it might be doing you some good,” he said.
