For some of us, the day doesn’t really begin until we get our caffeine fix. But not all coffee is created equal and the way it’s made has a lot to do with that. And it turns out, preparing it with a filter may even help you live longer, according to a new long-term study. Research published this week from the University of Gothenburg, Sweden, finds that unfiltered coffee contains substances that increase blood cholesterol, but using a filter gets rid of these and makes heart attacks and premature death less likely.
"Our study provides strong and convincing evidence of a link between coffee brewing methods, heart attacks and longevity," study author Dag Thelle explains.
The study followed close to half a million healthy Norwegians between the ages of 20 and 79 for 20 years. Results show drinking boiled or pressed unfiltered coffee raised the risk of death in men over 60 because of cardiovascular issues. That’s bad news for fans of coffee made with a French press or those who prefer strong Greek and Turkish coffee because these methods can actually increase your risk of heart disease.
Researchers found drinking filtered coffee, like the kind brewed through a paper filter, was healthier than not drinking coffee at all. The study found people who drank one to four cups of filtered coffee a day had the lowest mortality rate.
