Cafestol is a natural compound found in coffee, particularly in unfiltered varieties like French press or espresso. It is one of the main substances responsible for coffee's unique flavor and aroma. Unlike filtered coffee, which removes most of cafestol, unfiltered coffee retains higher amounts, leading to greater exposure for those who consume it regularly.
Understanding cafestol is important because it can influence heart health. Research indicates that cafestol may interfere with the liver's ability to remove low-density lipoprotein (LDL) cholesterol from the blood. Higher levels of LDL cholesterol can increase the risk of cardiovascular diseases, making it essential to be aware of how different coffee preparation methods can impact health.
In the body, cafestol works by affecting the metabolism of cholesterol. It may increase cholesterol levels by inhibiting certain receptors in the liver that help clear LDL cholesterol from the bloodstream. This effect can lead to elevated cholesterol levels if consumed in significant amounts over time, especially in those already at risk for heart disease.
While cafestol's impact on cholesterol is noteworthy, it is just one factor in a complex dietary landscape. Individuals should consider their overall diet, lifestyle, and health conditions when evaluating the effects of cafestol and other components in coffee.
