Coffee from vending machines often used in workplaces contains relatively high levels of cholesterol -enhancing substances.
It shows a new study.
“For big consumers who drink coffee every day, it is clear that brewing coffee or other well -filtered coffee is preferred,” says David Iggman, a researcher at Uppsala University, who has led the study.
It has already been known that cook coffee contains relatively high levels of the substances cafestol and kahweol, both of which raise the harmful cholesterol in the body. In a regular coffee maker, these substances are filtered away, but this does not apply in coffee machines that do not have as effective paper filters.
Now, for the first time, researchers have investigated how much of the harmful substances are in the vending machines.
– Considering how much coffee was drinking in Swedish workplaces, we wanted to find out what the content of cholesterol -enhancing substances looks like in that coffee, says David Iggman.
The coffee maker in the home safer
The researchers examined fourteen machines in a coffee room in different workplaces and could see that the levels of cafestol and Kahweol were significantly higher than in regular brew coffee.
– But the problem varies between different types of coffee machines and the concentrations have also had large variations between measurement occasions, says David Iggman.
Increased risk of cardiovascular disease
The majority of the coffee samples contained levels that can affect the content of blood fats. This poses an increased risk of cardiovascular disease.
– For big consumers who drink coffee every day, it is clear that brewing coffee or other well -filtered coffee is preferred, says David Iggman.
