The study, which was published in the July 11 issue of Annals of Internal Medicine, used data from the Multiethnic Cohort Study, a collaborative effort between the University of Hawaii Cancer Center and the Keck School of Medicine. The ongoing study begun in 1993 has more than 215,000 participants and bills itself as the most ethnically diverse study examining lifestyle risk factors that may lead to cancer.
In this current analysis of data collected from participants over the years, the researchers found that people who consumed a cup a coffee a day were 12 percent less likely to die compared to those who didn’t drink coffee. The link got stronger with increasing consumption, people who drank two to three cups a day had a 18 percent reduction in chance of death.
The effect didn’t vary whether people drank decaf or regular coffee or by ethnicity. The study is considered the most ethnically diverse study examining lifestyle risk factors that may lead to cancer, including African-Americans, Japanese-Americans, Latinos and Anglo-Americans.
"We cannot say drinking coffee will prolong your life, but we see an association," said Veronica W. Setiawan, lead author of the study and an associate professor of preventive medicine at the Keck School of Medicine of USC. "If you like to drink coffee, drink up! If you're not a coffee drinker, then you need to consider if you should start."
