Drink Coffee to Lower Your Risk of Early Death?

It seems like I can't stop writing about coffee (here and here). Coffee drinkers rejoice: another study (presented at the European Society of Cardiology) finds health benefits from drinking several cups of coffee daily. This study, like other previous studies, found an inverse relationship between drinking coffee and early death ("all-cause mortality") - meaning the more one drinks coffee, the less likely one is to have a premature death. The biggest effect was in drinking 4 cups daily in people aged 45 and older! It was an observational study, so can't prove it definitely - can only say there's an association. But still... it's looking good. From Medical Xpress:

Higher coffee consumption associated with lower risk of death

Higher coffee consumption is associated with a lower risk of death, according to research presented today at ESC Congress. The observational study in nearly 20,000 participants suggests that coffee can be part of a healthy diet in healthy people. 

The purpose of this study was to examine the association between coffee consumption and the risk of mortality in a middle-aged Mediterranean cohort. The study was conducted within the framework of the Seguimiento Universidad de Navarra (SUN) Project, a long-term prospective cohort study in more than 22,500 Spanish university graduates which started in 1999. This analysis included 19,896 participants of the SUN Project, whose average age at enrollment was 37.7 years old. .... Patients were followed-up for an average of ten years. 

During the ten year period, 337 participants died. The researchers found that participants who consumed at least four cups of coffee per day had a 64% lower risk of all-cause mortality than those who never or almost never consumed coffee. There was a 22% lower risk of all-cause mortality for each two additional cups of coffee per day.

The researchers examined whether sex, age or adherence to the Mediterranean diet had any influence on the association between baseline coffee consumption and mortality. They observed a significant interaction between coffee consumption and age. In those who were at least 45 years old, drinking two additional cups of coffee per day was associated with a 30% lower risk of mortality during follow-up. The association was not significant among younger participants.
