What are trans fats known to do to cholesterol levels?

Trans fats are known to negatively impact cholesterol levels in the body. They primarily raise levels of low-density lipoprotein (LDL), commonly referred to as "bad" cholesterol. Elevated LDL cholesterol is associated with an increased risk of heart disease, as it can lead to the buildup of plaques in the arteries. In addition to raising bad cholesterol levels, trans fats often lower high-density lipoprotein (HDL), the "good" cholesterol, which is beneficial for cardiovascular health. This dual effect on cholesterol profiles contributes significantly to the detrimental health outcomes associated with trans fat consumption.

Understanding this mechanism is essential when discussing dietary fats and their implications for health, particularly in relation to heart disease risk.
