Study shows coffee may help protect brain health in people with AFib

Atrial fibrillation, or AFib, is the most common type of heart arrhythmia in the U.S., and it’s expected to affect more than 12 million people by 2030. While common treatments like beta blockers and blood thinners are widely used, new research shows that coffee may offer added health benefits for people living with the condition.

A recent study by the American Heart Association found that drinking coffee may help reduce inflammation and slow cognitive decline in individuals with AFib. The findings suggest that people who consumed five cups of coffee per day had inflammation markers over 20 percent lower than those who drank less than one cup daily.

The study also linked higher coffee consumption to improved brain performance. Participants who drank between three and five cups daily showed up to an 11 percent improvement in areas like processing speed, visual motor coordination, and attention compared to non-coffee drinkers.

Caffeine appears to play a key role, with benefits increasing up to five or six cups per day. However, individuals who are sensitive to caffeine should be cautious, as even one or two cups may lead to restlessness or sleep disruption.

Experts also warn that sugary coffee drinks like lattes and flavored beverages can reduce potential health benefits due to their high calorie and sugar content.

According to the study, three to five eight-ounce cups of plain coffee per day can be part of a healthy diet for many people, including those with AFib.
