Study Associates Drinking Coffee with Lower Mortality Rates

There’s probably some truth to this research about coffee and mortality rates, but how much?

Drinking coffee was associated with a lower risk of death due to heart disease, cancer, stroke, diabetes, and respiratory and kidney disease for African-Americans, Japanese-Americans, Latinos and whites.

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.

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.

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.

Setiawan, who drinks one to two cups of coffee daily, said any positive effects from drinking coffee are far-reaching because of the number of people who enjoy or rely on the beverage every day.

“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.”

About 62 percent of Americans drink coffee daily, a 5 percent increase from 2016 numbers, reported the National Coffee Association.
