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.

Decaf makes about as much sense as “Fat Free” Half & Half.
i have a freshly picked daisy in my hands and am plucking petals: coffee good ... coffee bad ... coffee good ... coffee bad ... coffee good ...
red/black on a roulette wheel works too ...
Coffee has saved my life.
Specifically, without coffee, I would have undoubtedly killed several family members, resulting in my death from execution.
I had to decrease my caffeine intake because it plays hell with my arrhythmia. I try to space out the cups. I believe the half life of caffeine is about 4 hours.
Cool
Let’s all drink up to arrhythmia and joint pain.
I do every day.
seriously?
“Born to be wired.”
Nicotine destroys the plaques that cause Alzheimer’s.
Just chose your delivery system wisely.
That’s what beta blockers are for.
Yep, take those too.
Studies have shown of all POC’s and members of the LGBTQwhatever communities, at least 100% of them will die at some point in their lives. (in a
Hilary Clinton type screech) THIS IS UNACCEPTABLE!!!!
You don’t remember all the “drink more coffee” stories when Obama was in office?
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.”
More good news.
Between my wife’s great cooking skills and the great local fresh veggies/fruits, meats and seafood, this is more great news.
We start our mornings off with a couple of cups freshly ground coffee and have our glass of wine with a good dinner.
No tricky/expensive diets, starvation days nor expensive new B$ posing as live forever stuff with a minimum of carbs and zero prepared food.
Every year or two there's a new "study" that contradicts the one before it.
The pendulum is always going back and forth.
Guess the heavy cream in it cancels out the benefits.
“That’s what beta blockers are for.”
They, work and enable us to function better with our coffee.
I did learn not to take my Attenenol at bedtime as per the new studies re taking your heart meds at bedtime.
About a week later I started having chills and then hot flashed or reverse with hot flashes first and then chills.
Our PPO’s info sheet of Attenenol does not list this as a major side effect. However, Google searches showed it to be a major side effect.
So, I started taking my Attenenol with my morning pills and coffee.
In less than a week, the bedtime chills/hot flashes went away. I feel less jittery and sleep great.
My wife said that, when I was on the Attenenol at night, it was like being in bed with a blast furnace or a flash freeze unit.
So quite a way to get introduced to coffee drinking. But I developed a taste for it and when I got out, I continued drinking at least 2-4 cups a day. More when I'm on the road.
Anyway, during the past 40 years or so, I have read countless articles flip-flopping between "coffee is bad for you" and "coffee is good for you".
I guess if it was bad for me, I'd have some indications of it by now.
What about cocaine and wine intake?…
Asking for a friend?............................
In that case, my heart should beat for about 3 years after I’m dead.
