Saturated fats can increase bad cholesterol levels, but coffee consumption also contributes to this issue. Research reveals that coffee contains two cholesterol-elevating substances called cafestol and kahweol. The brewing method used can significantly impact the amount of these substances in your cup.
A new study from Sweden found that boiling coffee increased diterpenes, which raise cholesterol levels. However, paper filters have been shown to remove these elements, reducing the risk of cardiovascular disease.
The study compared 14 different coffee machines and brewing methods, including espresso makers, French presses, and boiled coffee with fabric filters. The results showed that boiled coffee contained the highest levels of diterpenes, while paper-filtered coffee remained the healthiest choice.
The researchers found that most coffee samples had levels of cafestol and kahweol that could affect LDL cholesterol levels and future cardiovascular disease risk. For daily coffee drinkers, using a well-filtered coffee brewing method can significantly reduce LDL cholesterol by 13% over five years and 36% over 40 years.
