Drinking at least 1 cup of coffee a day may help prevent heart failure

Science is once again supporting the health benefits of your daily dose of coffee.

Drinking at least one cup of coffee a day can reduce your risk of heart failure, and more coffee is associated with an even lower risk, according to a study published on February 9 in Circulation: Heart Failure, a journal of the American Heart Association .

The researchers analyzed data from three studies, including 21,000 adult participants over at least 10 years of follow-up. They found that each cup of caffeinated coffee that participants drank a day was associated with a 5% to 12% lower risk of heart failure, compared to participants who did not drink coffee. That happened with up to three cups of coffee a day, the research found.

Decaffeinated coffee was not related to the same benefits and, in fact, one study found that it was related to an increased risk of heart failure.

This suggests that caffeine is at least partly responsible for coffee’s health benefits, according to Dr. David Kao, senior author of the study and an assistant professor of cardiology at the University of Colorado School of Medicine.

“The association between caffeine and reduced risk of heart failure was surprising. Coffee and caffeine are often considered by the general population to be harmful to the heart because people associate them with palpitations, high blood pressure, etc.,” Kao said in a statement. the press.

The research is still not convincing enough to recommend that people who don’t drink coffee should start, based on health benefits, the study’s authors concluded. Particularly for heart health, the best advice is still to exercise, maintain a healthy weight and avoid smoking, Kao said in the press release.

If you do drink coffee, black is best

It is not yet clear how much coffee is better for health benefits – a limitation of this study is that it was based on self-reported data, without a clear definition of how much coffee people were drinking per cup. The researchers also did not collect data on the coffee preparation method; Previous research has found that methods like brewing with a filter can be healthier than the stove or French press preparations.

What we do know is that many of the benefits of coffee are linked to its pure consumption. Coffee in the form of sugary drinks or rich lattes usually contains sugar and saturated fat. These additives can increase the risk of heart disease, mitigating the benefits of coffee.

“The end result: enjoy coffee in moderation as part of a heart-healthy eating pattern that meets the recommendations for fruits and vegetables, whole grains, low-fat or non-fat dairy products and which is also low in sodium and saturated fat and added sugars, “said Penny Kris-Etherton, a nutritionist and professor of nutrition at Pennsylvania State University who was not involved in the study, in a press release.

Coffee is linked to health benefits like a longer life and better health as you age

This study adds evidence that drinking coffee regularly can improve heart health and prevent premature death. It can also help promote weight loss, prevent cognitive decline as we age, and provide some protection against other chronic illnesses like liver disease and various types of cancer.
