Summary: A new study from Sweden uncovers alarming risks associated with office coffee, revealing how brewing methods can raise cholesterol levels and potentially damage heart health. Here’s what the research says—and how you can protect your heart.
Introduction:
Coffee is a staple in most office routines—whether it’s the first thing you reach for in the morning or your afternoon pick-me-up. However, recent research has revealed that the coffee you’re drinking from the office machine may be more harmful to your heart than you think. According to a groundbreaking study conducted in Sweden, office coffee may be raising levels of “bad” cholesterol (LDL) and putting your cardiovascular health at risk.
The Study: A Deep Dive into Office Coffee Machines
Researchers examined coffee samples from 14 different coffee machines across four offices, using three types of brewing technology. Some machines used metal filters, others relied on liquid coffee concentrates, and some mixed freeze-dried instant coffee. When compared with coffee brewed at home using paper filters, the results were startling.
The study, published in the journal Nutrition, Metabolism, and Cardiovascular Diseases, showed that coffee brewed in office machines contained compounds that could lead to increased LDL cholesterol levels—specifically Cafestol and Kahweol, two naturally occurring substances found in coffee.

The Hidden Heart Risks: Cafestol and Kahweol
Both Cafestol and Kahweol are diterpenes found in coffee oils. These compounds have been linked to higher LDL cholesterol, which can increase the risk of heart disease. The study revealed that these compounds are more concentrated in coffee made from office machines, especially those using metal filters or liquid concentrates.
While these compounds are naturally present in all coffee, paper-filtered coffee—commonly brewed at home—doesn’t allow them to pass into the cup, offering a much healthier alternative for heart health.
Health Implications: Can Office Coffee Affect Your Heart?
The findings of the Swedish study suggest that drinking office coffee regularly could elevate your levels of LDL cholesterol. High LDL cholesterol is a significant risk factor for cardiovascular diseases, including heart attack and stroke. This highlights the importance of choosing the right type of coffee and brewing method—especially for those who rely on coffee as part of their daily routine.
Interestingly, the study also found that making a simple switch to paper-filtered coffee—consumed just three times a week—could help reduce LDL cholesterol levels over time. The results underscore the potential health benefits of changing your coffee habits to protect your heart.
What Should Office Workers Do? A Call to Action for Healthier Coffee
For employees, this research offers a simple solution: switch to coffee brewed at home with paper filters, or consider bringing in a coffee machine with a better filtration system. Office management, too, can play a role by investing in high-quality coffee machines that minimize the harmful effects of diterpenes on heart health.

Expert Opinions: Balancing the Benefits of Coffee
While this study raises concerns about the heart risks associated with office coffee, medical experts still emphasize the health benefits of coffee when consumed in moderation. Coffee is known to lower the risk of type 2 diabetes, Alzheimer’s disease, and liver conditions. However, the key is choosing the right brewing method to maximize these benefits without compromising heart health.
Conclusion: Small Changes for Better Heart Health
The good news is that protecting your heart from the harmful effects of office coffee may be simpler than you think. By making small adjustments to your coffee habits—whether brewing at home with a paper filter or asking for better office coffee machines—you can enjoy your favorite beverage while reducing health risks.
