How do trans fats negatively impact health?

Trans fats negatively impact health primarily because they can raise levels of low-density lipoprotein (LDL) cholesterol, often referred to as "bad" cholesterol, while simultaneously lowering high-density lipoprotein (HDL) cholesterol, known as "good" cholesterol. This dual effect contributes to an increased risk of cardiovascular diseases, as higher levels of LDL cholesterol are associated with the buildup of plaque in arteries, potentially leading to heart attacks or strokes. In contrast, HDL cholesterol is beneficial as it helps remove cholesterol from the bloodstream and brings it to the liver for excretion.

Understanding this harmful interaction is crucial for making informed dietary choices. Foods high in trans fats, such as partially hydrogenated oils commonly found in processed snacks and baked goods, can significantly disrupt lipid profiles and exacerbate health issues related to cardiovascular systems. Thus, a diet low in trans fats is recommended for maintaining healthy cholesterol levels and overall heart health.
