Why are trans fats discouraged according to ACC/AHA recommendations?

Trans fats are discouraged according to ACC/AHA recommendations because they contribute to cardiovascular disease. These unhealthy fats are typically found in partially hydrogenated oils, which are often present in processed foods. Trans fats can raise levels of LDL (low-density lipoprotein) cholesterol, often referred to as "bad" cholesterol, while simultaneously lowering levels of HDL (high-density lipoprotein) cholesterol, which is considered "good" cholesterol. This imbalance can lead to the development of plaque in the arteries, increasing the risk of heart disease and stroke.

In contrast, the other options do not accurately reflect the health implications of trans fats. They are not essential for health, do not provide low calories, and do not enhance nutrient absorption. Trans fats have considerable negative effects on health and are associated with increased morbidity and mortality related to cardiovascular issues. Hence, their consumption is strongly discouraged in dietary guidelines aimed at improving heart health and overall wellness.
