An observational study published in the European Journal of Preventive Cardiology took a closer look at the coffee habits of 508,747 men and women between the ages of 20 and 79 and found that drinking unfiltered coffee was associated with higher rates of heart disease and death than drinking filtered coffee.
The Norwegian study analysed data gathered over 18 years from 1985-2003 and relied on self-reported cases of coffee consumption and cardiovascular disease.
According to Aage Tverdal, a senior researcher at the Norwegian Institute of Public Health and lead author of the paper, he and his co-authors wanted to study the impact of different coffee brewing methods on heart health because it could be one of the many factors contributing to why some people who drink coffee see benefits and others do not.
Men who drank unfiltered coffee “had a higher mortality than the men not drinking coffee” and women who drank all three types of brews had “significantly lower” heart disease mortality, said Mr Tverdal.
