Is Too Much Coffee Bad for the Heart?

Just when I started to ramp up my ice coffee intake, I read this article.  An annual meeting for the European Society of Cardiology presented the findings of Italian researchers who linked the consumption of caffeine to higher risk of atrial fibrillation or irregular heartbeats.  When coupled with other dietary habits such as eating red meat, the risk for atrial fibrillation was even higher.  Subjects who followed a Mediterranean diet (whole grains, fruits, vegetables, and minimal red meat) were at a lower risk despite also consuming caffeine.  So if I get hazelnut coffee, would that minimize my risk?  Probably not, but it goes to show you that good dietary habits will allow you to enjoy other vices.
