Good news, coffee lovers: Your daily cup of joe could do some rote good, including helping reduce the risk of heart failure, new study results suggest.
In an analysis of data from three large studies on the subject, researchers found that overall, those who reported drinking one or more cups of caffeinated coffee per day had “a reduced risk of long-term heart failure.” , they said.
For the report, published Tuesday in Circulation: Heart Failure, a journal of the American Heart Association, researchers used machine learning to examine data from a large study from the Framingham Heart Study, referencing it to two others. studies, the Atherosclerosis Risk in Communities Study. and the cardiovascular health study, according to a press release on the results.
“Each study included at least 10 years of follow-up, and collectively the studies provided information on more than 21,000 American adult participants,” the researchers said.

When analyzing the Framingham Heart and Cardiovascular Health studies, the researchers noted that, compared to non-coffee drinkers, the risk of heart failure decreased by 5% to 12% for every cup drunk each day. Regarding the study on the risk of atherosclerosis in communities, the researchers noted that those who drank at least two cups of java per day had a 30% lower risk of heart failure, while the risk of Heart failure remained the same for those who drank only one cup or drank no cup of coffee per day.
When it comes to decaffeinated coffee, the researchers noted that this drink did not have the same benefits as caffeinated coffee, with one study suggesting that decaffeinated coffee has an opposite effect, possibly increasing the risk of heart failure.
Dr. David P. Kao, lead author of the study and assistant professor of cardiology and medical director at the Colorado Center for Personalized Medicine at the University of Colorado School of Medicine called the team’s metanalysis results “surprising”.
DIET DRINKS RELATED TO SAME HEART PROBLEMS AS SWEET DRINKS, STUDY SAYS
“The association between caffeine and reduced risk of heart failure was surprising. Coffee and caffeine are often considered by the general population to be “bad” for the heart because people associate them with palpitations, high blood pressure, etc. The consistent relationship between increased caffeine consumption and decreased risk of heart failure overturns this assumption, ”Kao said in a statement.
“However, there is not yet enough clear evidence to recommend increasing coffee consumption to decrease [the] risk of heart disease with the same strength and certainty as quitting smoking, losing weight or exercising, ”he noted.
The researchers also warned that the results were only for black coffee.

“While unable to prove causation, it is intriguing that these three studies suggest that coffee consumption is associated with a decreased risk of heart failure and that coffee can be part of a healthy diet if it is. eaten plain, no added sugar and no high fat dairy products. products like cream, ”said Penny M. Kris-Etherton, Ph.D., RDN, past chair of the Cardiovascular Health Council steering committee and from the Cardiovascular Health Council of the American Heart Association. Kris-Etherton is also Professor of Nutritional Sciences at Evan Pugh University and Distinguished Professor of Nutrition at Pennsylvania State University, College of Health and Human Development at University Park .
“Bottom Line: Enjoy coffee in moderation as part of an overall heart-healthy diet that meets recommendations for fruits and vegetables, whole grains, low-fat / fat-free dairy products, and is also low in sodium and saturated fat and added sugars, ”she added.“ Additionally, it’s important to keep in mind that caffeine is a stimulant and that consuming too much can be problematic – causing nervousness and sleeping problems. “
