Why should trans fats be avoided in the diet?

Trans fats should be avoided in the diet primarily because they increase heart disease risk. Trans fats are created through the process of hydrogenation, which transforms liquid oils into solid fats. This process not only extends the shelf life of processed foods but also alters the structure of the fats, leading to negative health effects.

Research has consistently shown that trans fats raise levels of LDL cholesterol, often referred to as "bad" cholesterol, while simultaneously lowering levels of HDL cholesterol, or "good" cholesterol. The imbalance created by trans fats contributes significantly to the development of atherosclerosis, where arteries become clogged with plaque, leading to increased risk of heart disease, stroke, and other cardiovascular conditions.

The extensive evidence linking trans fat consumption to adverse health outcomes has prompted public health initiatives to limit their use in food products, emphasizing the importance of maintaining a heart-healthy diet.
