Millions around the world start their day with a cup of coffee, and the good news is that new benefits are emerging for this beloved daily drink.
Recent research has shown that coffee may be better for heart health than previously thought.
Studies have also found that daily coffee consumption may help reduce the risk of developing type 2 diabetes.
There are many potential health benefits associated with drinking coffee, including increased energy, help with weight management, and possibly a reduced risk of depression.
However, it is important to note that these benefits may be reduced when large amounts of sugar and saturated fat, such as cream, are added to coffee.
Does coffee have a link to the risk of atrial fibrillation?
Doctors have long advised people with or at risk of developing atrial fibrillation to reduce or avoid coffee consumption.
However, the idea that coffee may increase the risk of atrial fibrillation has come under scrutiny in recent years.
A recent clinical trial challenged this idea, suggesting that coffee, rather than being a potential cause of atrial fibrillation, may reduce its recurrence.
The randomized controlled trial, named DECAF, found that among 200 adults diagnosed with atrial fibrillation or a similar condition, those who drank coffee daily were less likely to have recurrent episodes than those who avoided caffeine entirely over 6 months.
Cardiologist and professor of medicine at the University of California, San Francisco, and lead author of the study, Dr. Gregory Marcus, told Healthline:
* “There have been conflicting opinions about whether coffee affects atrial fibrillation.”
* “To our knowledge, this is the only long-term randomized study that has looked at the effect of caffeinated coffee on any cardiovascular outcomes.”
* “Caffeinated coffee may protect against atrial fibrillation, at least in people who enjoy drinking it and tolerate it well.”
At the end of the study, the researchers noted a 40% reduction in the risk of atrial fibrillation recurrence in individuals who regularly consumed coffee. The exact reason for this decrease remains unclear.
Maintaining Heart Health
An observational study conducted in 2025 concluded that coffee may be beneficial for heart and general health, especially when consumed without additives.
The researchers reported that individuals who consumed 1 to 3 cups of caffeinated black coffee daily, with little or no sugar or saturated fat, had a 14% lower risk of death and a lower risk of death from cardiovascular disease, compared to those who did not consume coffee.
However, the researchers also noted that consuming more than 3 cups of coffee daily was not associated with a further reduction in risk. No reduction in risk was also observed in those who added large amounts of sugar or fat to their coffee.
