Research Highlights:
Analysis of three large, well-known heart disease studies found drinking one or more cups of caffeinated coffee was associated with decreased heart failure risk.
Drinking decaffeinated coffee did not have the same benefit and may be associated with an increased risk for heart failure.
There is not yet enough clear evidence to recommend increasing coffee consumption to decrease risk of heart disease with the same strength and certainty as stopping smoking, losing weight or exercising.
==================================================================================
Dietary information from three large, well-known heart disease studies suggests drinking one or more cups of caffeinated coffee may reduce heart failure risk, according to research published today in Circulation: Heart Failure, an American Heart Association journal.
Coronary artery disease, heart failure, and stroke are among the top causes of death from heart disease in the U.S. “While smoking, age and high blood pressure are among the most well-known heart disease risk factors, unidentified risk factors for heart disease remain,” according to David P. Kao, M.D., 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 topics of ongoing scientific interest due to the popularity and frequency of consumption worldwide,” said Linda Van Horn, Ph.D., R.D., professor and Chief of the Department of Preventive Medicine’s Nutrition Division at the Northwestern University Feinberg School of Medicine in Chicago, and member of the American Heart Association’s Nutrition Committee. “Studies reporting associations with outcomes remain relatively limited due to inconsistencies in diet assessment and analytical methodologies, as well as inherent problems with self-reported dietary intake.”

Kao and colleagues used machine learning through the American Heart Association’s Precision Medicine Platform to examine data from the original cohort of the Framingham Heart Study and referenced it against data from both the Atherosclerosis Risk in Communities Study and the Cardiovascular Health Study to help confirm their findings. Each study included at least 10 years of follow-up, and, collectively, the studies provided information on more than 21,000 U.S. adult participants.
To analyze the outcomes of drinking caffeinated coffee, researchers categorized consumption as 0 cups per day, 1 cup per day, 2 cups per day and ≥3 cups per day. Across the three studies, coffee consumption was self-reported, and no standard unit of measure were available.
The analysis revealed:
In all three studies, people who reported drinking one or more cups of caffeinated coffee had an associated decreased long-term heart failure risk. In the Framingham Heart and the Cardiovascular Health studies, the risk of heart failure over the course of decades decreased by 5-to-12% per cup per day of coffee, compared with no coffee consumption. In the Atherosclerosis Risk in Communities Study, the risk of heart failure did not change between 0 to 1 cup per day of coffee; however, it was about 30% lower in people who drank at least 2 cups a day. Drinking decaffeinated coffee appeared to have an opposite effect on heart failure risk – significantly increasing the risk of heart failure in the Framingham Heart Study. In the Cardiovascular Health Study however; there was no increase or decrease in risk of heart failure associated with drinking decaffeinated coffee. When the researchers examined this further, they found caffeine consumption from any source appeared to be associated with decreased heart failure risk, and caffeine was at least part of the reason for the apparent benefit from drinking more coffee. “The association between caffeine and heart failure risk reduction 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 turns that assumption on its head,” Kao said. “However, there is not yet enough clear evidence to recommend increasing coffee consumption to decrease risk of heart disease with the same strength and certainty as stopping smoking, losing weight or exercising.”
Happy Couple Drinking Coffee
According to the federal dietary guidelines, three to five 8-ounce cups of coffee per day can be part of a healthy diet, but that only refers to plain 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. In addition, despite its benefits, research has shown that caffeine also can be dangerous if consumed in excess. Additionally, children should avoid caffeine. The American Academy of Pediatrics recommends that, in general, kids avoid beverages with caffeine.
“While unable to prove causality, it is intriguing that these three studies suggest that drinking coffee is associated with a decreased risk of heart failure and that coffee can be part of a healthy dietary pattern if consumed plain, without added sugar and high fat dairy products such as cream,” said Penny M. Kris-Etherton, Ph.D., R.D.N., immediate past chairperson of the American Heart Association’s Lifestyle and Cardiometabolic Health Council Leadership Committee, Evan Pugh University Professor of Nutritional Sciences and distinguished professor of nutrition at The Pennsylvania State University, College of Health and Human Development in University Park. “The bottom line: enjoy coffee in moderation as part of an overall heart-healthy dietary pattern that meets recommendations for fruits and vegetables, whole grains, low-fat/non-fat dairy products, and that also is low in sodium, saturated fat and added sugars. Also, it is important to be mindful that caffeine is a stimulant and consuming too much may be problematic – causing jitteriness and sleep problems.”
Study limitations that may have impacted the results of the analysis included differences in the way coffee drinking was recorded and the type of coffee consumed. For example, drip, percolated, French press or espresso coffee types; origin of the coffee beans; and filtered or unfiltered coffee were details not specified. There also may have been variability regarding the unit measurement for 1 cup of coffee (i.e., how many ounces per cup). These factors could result in different caffeine levels. In addition, researchers caution that the original studies detailed only caffeinated or decaffeinated coffee, therefore these findings may not apply to energy drinks, caffeinated teas, soda and other food items with caffeine including chocolate.

Oh, this again. All the “coffee is good for you so drink more of it” propaganda that abounded during the Obama years is back . . .
Ping-a-roonie!.....................
I will live forever, my heart will never stop. 24 oz minimum every day, with a little bit more to get me through the meetings.
of course. Why go for a job when you can spend 4 hours of your morning sat on your duff whilst the caffiene raises your heart rate an average of 10bpm?
Lol. Perfect. In the last couple of weeks there was another “study” saying the opposite, that coffee was bad. Some Freeper back then accurately predicted that an article like this would soon follow.
jog*
2021 is an odd-numbered year, so I guess that means coffee is good for us this year.
A study in 2022 will declare it to be very unhealthy.
But, by 2023, it will be healthy again.
Eggs too.
ah yes, the consensus “experts” chime in once again.
fortunately experience taught me they were wrong years ago, when i didn’t die after consuming mass quantities of coffee for years as an engineer.
Headline, 6 months from now:
“Scientists determine that coffee consumption may lead to increased risk of heart disease”.
Coffee has different effects on people. My mother drank it all day, black, and had a cup before bed to help her sleep. She lived to 92.
If I have more than 2 cups I break out in a sweat and get very anxious. I drink nothing else that’s got caffeine, ever.
I’m waiting for one that says Captain Morgan rum is good for you and improves your eyesight.
And next month, they’ll say the opposite.
So, I might end up with Alzheimer’s but at least my ticker will be in good shape?
Interesting claims about the unhealthiness of decaf. Not sure I buy it, but I’ve long considered decaf a waste of time. I suppose that some people just love the taste of coffee but don’t want the caffeine jolt. To each his own, I guess. But I’m not one of those people. It’s like non-alcoholic beer, IMO. If you’re going to drink a beer, drink a beer.
Captain Morgan improves your ability to speak like a pirate
“ and had a cup before bed to help her sleep. She lived to 92.
Wise woman.
I drink a cup before bed to give me the strength to sleep well.
You will lay awake in your grave wondering who you are......................
LMAO!!!
You need to drink organic, shade tree grown coffee, readily available at any health food store.
Most coffee ( including Starbucks ) is not organic, and coffee crops generally employ a more heavy use of pesticides than other crops.
