What's the basis for those statements? Especially the "five cups a day" one. The article says otherwise, which is one of the interesting things about it. > Importantly, consuming any amount of coffee was not associated with a higher risk of heart rhythm problems, including atrial fibrillation (AFib) or atrial flutter, which Kistler said is often what clinicians are concerned about. I'm also looking at the Wikipedia article on the health effects of coffee, and it seems like 4 cups a day is sort of the sweet spot for a lot of positive effects, but I don't see anything about more than that being bad in most cases. > A 2012 meta-analysis concluded that people who drank moderate amounts of coffee had a lower rate of heart failure, with the biggest effect found for those who drank more than four cups a day. Five cup a day drinker over here, so I'd love to know if you have conflicting sources.
