Experts from the University of Gothenburg in Sweden determined that coffee prepared with a French press or without a filter is the most dangerous coffee for cardiovascular health. The study was published on: magazine European Journal of Preventive Cardiology (EJPC).
Researchers analyzed data from nearly 509,000 Norwegians of both genders, aged 20 to 79. Their observations continued for an average of twenty years. Study participants regularly reported their diets, including how much coffee they drank and how they brewed it.
Analysis of data on the participants’ diet, health status and cause of death showed that the habit of drinking coffee is not harmful, but it all depends on the method of brewing the drink. For example, drinking a filtered beverage is associated with a 12 percent reduction in the risk of premature death from cardiovascular disease in men and a 20 percent reduction in women. The lowest mortality rate was seen in those who drank 1 to 4 cups of filter coffee per day.
The most dangerous was coffee made using a French press. Due to the lack of filtration, this type of coffee contains a very high amount of substances that increase the level of cholesterol in the blood. It has about 30 times more than filtered coffee.
