- A 2025 study found that coffee drinkers may have a 40% lower risk of AFib recurrence.
- More research from 2025 shows that drinking black coffee daily can lower a person’s overall mortality risk and their risk of death from cardiovascular disease.
- Another study from 2025 found that the polyphenols in black coffee may lower the risk of type 2 diabetes.
Many people enjoy starting their day with a cup (or two) of coffee. Approximately 66% of adults in the United States drink coffee on a daily basis.
Recent research has shown that coffee may be better for your heart than originally thought. Studies have also found that daily coffee consumption may also help reduce your risk of type 2 diabetes.
There are various potential health benefits associated with drinking coffee, including boosting energy, aiding in weight management, and potentially reducing the risk of depression.
However, it is essential to note that these benefits may diminish if you add significant amounts of sugar and saturated fats, such as cream, to your coffee. Experts recommend reducing your caffeine intake if you are pregnant or nursing.
Is coffee linked to AFib risk?
Conventional medical wisdom has generally advised people who have atrial fibrillation (AFib) or who are at risk of it to cut back or avoid coffee.
However, the idea that coffee can lead to an increased risk of AFib has been scrutinized in recent years.
A recent clinical trial further challenged this idea. It suggested that instead of potentially triggering AFib, coffee may actually reduce the frequency. The trial results were published in JAMA near the end of 2025.
The randomized controlled trial, called DECAF, found that among 200 adults diagnosed with AFib or a related condition, atrial flutter, and with a history of AFib, those who drank coffee daily had fewer recurrent episodes than those who avoided caffeine entirely over a 6-month period.
“There have been conflicting thoughts about whether coffee affects atrial fibrillation,” Gregory Marcus, MD, a cardiologist and professor of medicine at the San Francisco, and senior author of the research, told Healthline.
“To our knowledge, this is the only long-term randomized trial of caffeinated coffee on any cardiovascular endpoint. It suggests that caffeinated coffee may protect against atrial fibrillation, at least among people that otherwise enjoy and tolerate caffeinated coffee,” he added.
At the end of the trial, the researchers saw a 40% lower risk of AFib recurrence among the individuals who regularly consumed coffee. The exact reasoning behind this reduction is still unclear.
The authors suggest that blocking adenosine may confer antiarrhythmic properties to caffeine. Adenosine is a naturally occurring chemical in the body that makes you feel drowsy. It’s part of how the body regulates energy and sleep cycles, but it’s also known to trigger AFib.
Another suggestion relates to the anti-inflammatory properties in coffee that may protect against AFib.
“Coffee, as we know, naturally contains antioxidant properties, such as chlorogenic acids and
