A new long-term study from the European Journal of Preventive Cardiology has shown that coffee, if prepared the right way, could be good for you and even extend your life.

The study followed over half a million Norwegian men and women between the ages of 20 and 79 over a 20-year period.

According to the study, unfiltered coffee contains substances that increase blood cholesterol. Using a filter removes these and makes “heart attacks and premature death less likely.”. The finding that those drinking the filtered beverage did a little better than those not drinking coffee at all could not be explained by any other variable such as age, gender or lifestyle habits.

So we think this observation is true, Study author Dag Thelle, via CNN. Methods like boiling or using any kind of coffee press have all been found to increase risk of heart disease. Using a French press, Greek or Turkish brewing methods, could actually be bad for your health.

Other takeaways included limiting coffee intake for pregnant woman and avoiding adding sugar to coffee.
