Study Links Drinking 2-3 Cups of Coffee Daily to Lower Atrial Fibrillation Risk

A prospective study of nearly 500,000 UK Biobank participants over 13 years found that consuming 2 to 3 cups of coffee daily is associated with a 7% to 11% reduced risk of atrial fibrillation. Tea consumption showed a smaller and less consistent association with a 5% lower risk at similar intake levels. The study is observational and does not establish causation.
