Study Finds Link Between Coffee Drinking and Reduced Risk of Premature Death

A large, long-term study conducted by the Harvard School of Public Health has found that coffee intake is directly correlated with a lower risk of deaths resulting from heart disease and certain other ailments. Researchers tracked the diet and behavior, including coffee intake, of 200,000 doctors and nurses over a period of 30 years. Subjects also participated in periodic physical exams under the study, which was recently published in the American Heart Association journal Circulation.

Participants who drank one cup of coffee per day experienced a 6 percent lower risk of premature death compared to abstainers. Those who drank one to three cups had an 8 percent lower risk of premature death, while those who drank three to five cups of coffee a day reduced this risk by 15 percent. Drinkers of caffeinated and decaffeinated coffee experienced little variance with regard to these benefits. Researchers controlled for body mass index, alcohol intake, age, and other potential factors relating to subjects’ diet and overall health.

The study linked coffee intake to reduced risk of neurological disease, heart disease, diabetes, and stroke. No statistically significant findings were found between coffee drinking and the risk of contracting cancer.

Dr. Ming Ding, lead author of the study, warned that although the results of the study are encouraging,

Our study is observational, so it’s hard to know if the positive effect is causal or not.

Coffee drinking has been linked in previous studies to a reduced risk of type 2 diabetes, liver disease, liver cancer, Parkinson’s, and heart disease.
