Do workplace coffee machines pose health risks?

A recent study has raised concerns about the health effects of coffee machines commonly found in workplaces. Researchers from Uppsala University and Chalmers University of Technology discovered that these machines can produce substances linked to higher cholesterol levels, potentially increasing the risk of heart disease among employees.

The study focused on the two coffee-specific compounds, cafestol and kahweol, which have been associated with elevated LDL cholesterol levels. The researchers examined 14 different coffee machines and found that those using brewing methods tended to have the highest concentrations of these substances. David Iggman, a researcher involved in the study, noted that coffee made from these machines contained levels of cafestol and kahweol that could affect the cholesterol levels of those who drank it.

One of the main reasons for the higher levels of these compounds is that brewing machines often lack fine filters, allowing more of the cholesterol-elevating substances to pass through into the coffee. Iggman emphasized the importance of the filtering process, stating that not all coffee machines effectively remove these harmful substances. The study also highlighted significant variations in diterpene concentrations over time, depending on the type of machine used.

As many companies introduce free coffee as a perk to encourage employees to return to the office, these findings could have implications for workplace health policies. In fact, a survey revealed that a majority of employees consider having free beverages a valuable workplace benefit. The report indicated that 66% of on-site workers prefer a hot cup of coffee as their first drink of the day, with many needing two to three cups to stay productive.

Given the study’s findings, employers may want to reassess the types of coffee machines they provide. Regular drip-filter coffee makers, which use paper filters, can almost completely eliminate cafestol and kahweol, making them a healthier choice. Iggman recommends that employees who consume large amounts of coffee should opt for well-filtered options to support their cardiovascular health.

In summary, while coffee can be a beloved workplace staple, this new research suggests that the type of coffee machine in use could have serious health implications. Employers and employees alike might need to consider switching to machines that filter out these harmful substances to promote better health in the workplace.
