Filtered coffee may cut cholesterol and heart disease risk by 36%

The way coffee is brewed plays a bigger role in its health effects than many realise. New findings highlight how certain methods can raise cholesterol levels, while others offer clear benefits. This has led health experts to recommend filtered coffee over unfiltered alternatives for long-term wellbeing. All coffee contains two natural compounds, cafestol and kahweol, which affect cholesterol. These substances remain in the beans no matter how they are roasted or ground. The key difference comes from how the coffee is prepared.

Unfiltered methods, such as French press, espresso, and boiled coffee, let these compounds pass into the cup. Workplace coffee machines with metal filters also fail to block them, leading to higher cholesterol in the brew. In contrast, paper filters trap most of these compounds, acting like a tiny barrier for better health. Health authorities, including the Nordic Nutrition Recommendations, now advise choosing filtered coffee. Studies suggest switching from high-diterpene machine coffee to filtered drip coffee could lower LDL cholesterol by 0.58 mmol/L. Over time, this change may reduce heart disease risk by 13% in five years and 36% over four decades.

For those concerned about cholesterol, paper-filtered coffee is the safest choice. Drip-filtered or pour-over methods provide a simple way to enjoy coffee while lowering long-term health risks. The brewing process, not just the beans, makes the difference in a healthier daily habit.
