Drinking coffee is linked to many health benefits, such as less weight gain, lower average daily blood pressure, and a reduced risk for diabetes and cardiovascular disease. But which brewing method will help you get the most from your cup?
A study published online April 22, 2020, by the European Journal of Preventive Cardiology found that filtering coffee (for example, with a paper filter) — not just boiling ground coffee beans and drinking the water — was better for health, particularly for older people. Researchers analyzed the survey responses of more than 500,000 healthy coffee drinkers (ages 20 to 79) who were followed for about 20 years.
People younger than 60 who drank one to four cups of coffee, particularly filtered coffee, had lower rates of artery disease and death. The lower rate of death with filtered coffee drinkers persisted in people ages 60 or older, but was lost in people who drank five or more cups per day.
The study is observational and doesn’t prove that filtered coffee is healthier than unfiltered coffee, but it makes sense. Unfiltered coffee contains diterpenes, compounds that can raise cholesterol, and researchers say a cup of unfiltered coffee contains 30 times more diterpenes than a cup of filtered coffee.
So use that coffee filter, save the French press or Turkish unfiltered coffee for rare occasions, and consider limiting your coffee intake to less than five cups per day, on average.
