A group of Swedish scientists from the University of Uppsala University and the University of Technology found that most of the office coffee machine contains high levels of substances that increase cholesterol. The study was published scientifically magazine Nutrition, metabolism and cardiovascular diseases (NMCD).
The team analyzed the coffee of 14 coffee machines used in the workplaces in Sweden. This coffee contains significantly more Diterpen – Kafestol and Kahveol – than the coffee prepared in ordinary coffee makers with paper filter.
These substances are known for their ability to increase the level of LDL cholesterol (“bad” cholesterol), which can increase the risk of cardiovascular disease.
“The filtration process is very important. All coffee machines cannot effectively filter these substances and their concentrations may vary depending on the type of machine and the cooking time,” he said.
Scientists also compared the prepared coffee in different ways. Hot machines (the most common in offices) – showed the highest Diterpen levels.
For the preparation of Espresso, the levels have changed, but some examples contained too many diterpen.
The coffee source prepared with boiling method was the leader in the content of all harmful substances. At the same time, the coffee filtered from the paper filter was almost completely cleaned from the Derephs.
Researchers recommend using coffee machines with paper filters to reduce diterpenler, as well as limiting coffee consumption from welding machines and other methods that do not provide enough filtration.
Previously, scientists They called A factor that makes a person sensitive above.
