You can see the results here. Compared with non-drinkers, coffee drinkers had a lower risk of death. In fact, there was a bit of a dose-response effect here – with more coffee being more protective. Cheers.”

This interesting article published by Medpage Today is about a study done on the lifespans of coffee drinkers. It concludes that coffee drinkers do indeed live longer than non-coffee drinkers, but some of the results are making experts a bit skeptical that that’s all there is to it.
What’s the Issue?
Before the study was conducted, the participants were genetically tested. One of the important pieces of data was how well an individual can metabolize caffeine. In the study, coffee drinkers with this fast caffeine metabolism experienced the same benefits as those with slower metabolisms. This means that the caffeine was in their bodies for less time, which theoretically means it shouldn’t have benefited them as much. Furthermore, to make things even more confusing, decaffeinated coffee provided the same life extending benefits. If it was the caffeine in coffee that was helping us, decaffeinated coffee shouldn’t have had any benefits.
So There’s No Actual Benefit to Drinking Coffee?
Not necessarily. One of the possibilities is that it isn’t the caffeine in coffee that’s helping us, but other ingredients that are less noticeable in comparison. The article compares this to being like ‘testing for the benefits of Vitamin C while mixing it with cocaine’. Another possibility is that it isn’t because of the coffee at all, but the type of person who drinks it. In other words, people likely to be coffee drinkers are also likely to be the kind of people who live a lifestyle that makes them live longer. Unfortunately, confirming any of these possibilities would likely require extensive studies in and of themselves. On the bright side, this means further testing is required, which means lots more coffee to drink.
