In a study of more than 180,000 participants, researchers at the University of Southern California found that people who regularly drank regular coffee, or decaffeinated coffee, were healthier, lived longer, for example, and were less likely to develop many cancers and chronic diseases. Now we have another reason to start the day with a cup of coffee. Scientists have found that coffee drinkers seem to live longer.

Coffee drinking was associated with a lower risk of death from heart disease, cancer, stroke, diabetes and respiratory and kidney disease in a study of African-American, Japanese-American, Hispanic and Caucasian Americans.

Those who drank one cup of coffee a day were 12 percent less likely to die than those who did not drink coffee. The association was even stronger among people who drank two to three cups of coffee a day--an 18 percent reduction in mortality.

Veronica W. Setiawan, associate professor of preventive medicine at the University of Southern California's Keck School of Medicine and lead author of the study, said: "We're not going to do anything about it. Setiawan said: "Mortality was lower whether participants drank regular or decaffeinated coffee, suggesting that this association is not coffee dependent and therefore exists." Although we can't say that drinking coffee prolongs life, we see this correlation. If you like coffee, drink it! If you don't drink coffee, you need to think twice about whether to start."

The work, published July 11 in Annals of Internal Medicine, is a multiracial cohort study conducted in collaboration with the University of Hawaii Cancer Center and the University of Southern California Keck School of Medicine.

The ongoing Multiethnic Cohort Study, which includes more than 215000 participants, is the most ethnically diverse of all studies analyzing lifestyle risk factors for cancer so far.

"Until now, there has been little data on the association between coffee intake and mortality in nonwhite populations, both in the United States and elsewhere," the authors note in the paper. However, these studies are important because there are significant differences in lifestyle and disease risk among people of different races and ethnic backgrounds. What researchers find in one group does not necessarily apply to others.“

"As the largest study of its kind to date, this work included four ethnic groups with very different lifestyles, but all reached similar conclusions, suggesting that there is a common biological basis behind this phenomenon." As a result, setiawan argues,"coffee is good for you whether you're white, african american, latino or asian."

Benefits of Coffee

Scientists from the University of Southern California and other institutions have previously found that coffee drinking is associated with a reduced risk of cancer, diabetes, liver disease, Parkinson's disease and other chronic diseases.

Setiawan himself drinks 1- 2 cups of coffee a day, and he believes that since many people like to drink or rely on coffee every day, any positive effects from drinking coffee will be far-reaching.

"Coffee is rich in antioxidants and phenolic compounds, which play an important role in cancer prevention," Setiawan said."Although the study did not include Caucasians and did not identify specific chemicals in coffee that contribute to longevity, it is clear that coffee can be added to the list of healthy diets and lifestyles."

According to the National Coffee Association, about 62 percent of Americans drink coffee daily, up 5 percent from 2016.

As a research institution, USC scientists have been collaborating across disciplines to find cures for cancer and better disease management.

The Keck School of Medicine and the Norris Comprehensive Cancer Center at the University of Southern California jointly manage a state database called the Los Angeles Cancer Surveillance Program, which provides scientists with basic cancer statistics for multiple ethnic groups.

Coffee drinking may reduce the risk of colorectal cancer, but drinking hot coffee or beverages may lead to esophageal cancer, researchers found.

Voice from WHO

In some ways, coffee is regaining its reputation as "healthy." Twenty-five years after coffee was identified as a bladder cancer-related carcinogen, the World Health Organization (WHO) announced last year that coffee consumption reduces the risk of liver and uterine cancer.

"Some people worry that drinking coffee may be harmful to health because it may increase the risk of heart disease, growth retardation, stomach ulcers and heartburn, but research shows that coffee is not harmful to people's health in the vast majority of cases." Setiawan said.

Coffee related numbers

Setiawan and colleagues looked at data on 185855 subjects aged 45 to 75, including 17 percent African-American, 7 percent Native Hawaiian, 29 percent Japanese-American, 22 percent Latino, and 25 percent white. Participants received questionnaires about diet, lifestyle, family and personal disease history.

Participants reported their coffee drinking habits in the survey, updating them about every five years. Participants chose from nine options ranging from "never/hardly ever" to "four or more cups per day" and also stated whether the coffee they drank contained caffeine. Participants were followed for an average of 16 years.

Sixteen percent said they never drank coffee, 31 percent said they drank one cup a day, 25 percent said they drank two to three cups a day, 7 percent said they drank four or more cups, and the remaining 21 percent said they did not drink coffee regularly.

During follow-up, 58397 participants (31%) died, with cardiovascular disease (36%) and cancer (31%) being the leading causes of death. The data were adjusted for age, sex, race, smoking habits, education level, pre-existing diseases, physical activity and alcohol intake.

Setiawan has found in previous studies that coffee reduces the risk of liver cancer and chronic liver disease. Now she is assessing how coffee correlates with the risk of developing certain types of cancer.
