Scientists in University of Southern California have found that people who drink coffee appear to live longer. Drinking coffee was associated with lower risk of death due to heart disease, cancer, stroke, diabetes, and kidney disease.
People who consumed a cup of coffee a day were 12 percent less likely to die compared to those who didn’t drink coffee. This association was even stronger for those who drank two to three cups a day — 18 percent reduced chance of death.
The study, which was expected to be 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.
Lower mortality was present regardless of whether people drank regular or decaffeinated coffee, suggesting the association is not tied to caffeine, said Veronica W. Setiawan, lead author of the study and an associate professor of preventive medicine at the Keck School of Medicine of USC.
“We cannot say drinking coffee will prolong your life, but we see an association,” Setiawan said. “If you like to drink coffee, drink up! If you’re not a coffee drinker, then you need to consider if you should start.”
“Until now, few data have been available on the association between coffee consumption and mortality in nonwhites in the United States and elsewhere,” the study stated. “Such investigations are important because lifestyle patterns and disease risks can vary substantially across racial and ethnic backgrounds, and findings in one group may not necessarily apply to others.”
Since the association was seen in four different ethnicities, Setiawan said it is safe to say the results apply to other groups.
“This study is the largest of its kind and includes minorities who have very different lifestyles,” Setiawan said. “Seeing a similar pattern across different populations gives stronger biological backing to the argument that coffee is good for you whether you are white, African-American, Latino or Asian.”
Benefits of drinking coffee
Previous research by USC and others have indicated that drinking coffee is associated with reduced risk of several types of cancer, diabetes, liver disease, Parkinson’s disease, Type 2 diabetes and other chronic diseases.
“Coffee contains a lot of antioxidants and phenolic compounds that play an important role in cancer prevention,” Setiawan said. “Although this study does not show causation or point to what chemicals in coffee may have this ‘elixir effect,’ it is clear that coffee can be incorporated into a healthy diet and lifestyle.”
“Some people worry drinking coffee can be bad for you because it might increase the risk of heart disease, stunt growth or lead to stomach ulcers and heartburn,” Setiawan said. “But research on coffee have mostly shown no harm to people’s health.”
