According to a study published today in Circulation: Heart Failure, a journal of the American Heart Association, dietary information from three large, well-known studies on heart disease suggests that drinking one or more cups of caffeinated coffee may reduce the risk of heart failure.
Coronary artery disease, heart failure and stroke are among the leading causes of death from heart disease in the United States. “While smoking, age and hypertension are among the most well-known risk factors for heart disease, unidentified risk factors for heart disease remain,” according to David P. Kao, MD, senior author of the study, assistant professor of cardiology and medical director at the Colorado Center for Personalized Medicine at the University of Colorado School of Medicine in Aurora, Colorado.
“The risks and benefits of drinking coffee have been a topic of continuing scientific interest due to the popularity and frequency of consumption around the world,” said Linda Van Horn, Ph.D., RD, Professor and Head of the Nutrition Division of the Department of Preventive Medicine at Northwestern University Feinberg School of Medicine in Chicago and member of the American Heart Association Nutrition Committee. “Studies reporting associations with outcomes remain relatively limited due to inconsistencies in diet assessment and analytical methodologies, as well as problems inherent in self-reported dietary intake.
Kao and his colleagues used machine learning through the American Heart Association’s Precision Medicine Platform to examine data from the original Framingham Heart study cohort and benchmark it against the study data on the risk of atherosclerosis in communities and the cardiovascular health study to help confirm their 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.
To analyze the results of consuming caffeinated coffee, the researchers categorized consumption as: 0 cups per day, 1 cup per day, 2 cups per day, and 3 cups per day. In all three studies, coffee consumption was self-reported and no standard unit of measure was available.
The analysis revealed:
– In all three studies, people who reported drinking one or more cups of caffeinated coffee had a reduced risk of long-term heart failure.
– In the Framingham Heart and Cardiovascular Health studies, the risk of heart failure over decades was reduced by 5-12% per cup per day of coffee, compared to no coffee consumption.
– In the study on the risk of atherosclerosis in the communities, the risk of heart failure did not vary between 0 and 1 cup of coffee per day; however, it was about 30% lower in people who drank 2 or more cups per day.
Drinking decaffeinated coffee appears to have an opposite effect on the risk of heart failure – dramatically increasing the risk of heart failure in the Framingham Heart study. In the cardiovascular health study however; there was no increase or decrease in the risk of heart failure associated with the consumption of decaffeinated coffee. When the researchers looked at this in more detail, they found that consuming caffeine from any source appeared to be associated with a decreased risk of heart failure, and caffeine was at least a part of it. because of the apparent benefit of drinking more coffee.
“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 increasing caffeine consumption and decreasing heart failure risk points to this assumption, ”Kao said. “However, there is not yet enough clear evidence to recommend increasing coffee consumption to reduce the risk of heart disease with the same strength and certainty as quitting smoking, losing weight or to exercise. “
According to federal dietary guidelines, three to five 8-ounce cups of coffee per day may be part of a healthy diet, but this only refers to regular black coffee. The American Heart Association warns that popular coffee-based drinks such as lattes and macchiatos are often high in calories, added sugar, and fat. Plus, despite its benefits, research has shown that caffeine can also be dangerous if consumed in excess. Additionally, children should avoid caffeine. The American Academy of Pediatrics recommends that in general, children avoid drinks that contain caffeine.
“While they cannot 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 may be part of a healthy diet. ‘it is consumed plain, without added sugar and without dairy products rich in fat. like cream, ”said Penny M. Kris-Etherton, Ph.D., RDN, past chair of the American Heart Association’s Lifestyle and Cardiometabolic Health Council Leadership Committee, Evan Pugh University professor of nutritional science and Distinguished Professor of Nutrition at The 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 Also, it’s important to keep in mind that caffeine is a stimulant and consuming too much can be problematic – causing nervousness and sleep problems. “
Limitations of the study that may have impacted the results of the analysis included differences in how coffee consumption was recorded and the type of coffee consumed. For example, drip, percolate, French press or espresso types of coffee; origin of coffee beans; and filtered or unfiltered coffee were unspecified details. There may also have been variability in the unit measurement for 1 cup of coffee (ie How many ounces per cup). These factors could cause different caffeine levels. Additionally, the researchers caution that the original studies only detailed caffeinated or decaffeinated coffee, therefore, these findings may not apply to energy drinks, caffeinated teas, sodas, and other caffeinated foods. , including chocolate.
