How do trans fats affect cholesterol levels in the body?

Trans fats have a well-documented impact on cholesterol levels in the body. They are known to increase levels of low-density lipoprotein (LDL), often referred to as "bad" cholesterol, while simultaneously lowering high-density lipoprotein (HDL), known as "good" cholesterol. This dual effect can lead to an increased risk of cardiovascular disease, as high levels of LDL cholesterol are associated with plaque buildup in arteries, and low levels of HDL cholesterol reduce the body's ability to clear cholesterol away from the arteries.

Research indicates that consuming trans fats can negatively influence cholesterol profiles, contributing to an imbalance that heightens the risk of heart disease. Unlike some fats that may be beneficial or neutral in their cholesterol impact, trans fats consistently produce harmful effects on both LDL and HDL levels, which is a significant reason why many health organizations have called for reductions in trans fat consumption in diets.
