What are trans fats and why should they be avoided?

Trans fats are a type of unsaturated fat that have been chemically altered through a process called hydrogenation, which turns liquid vegetable oils into solid fats. This transformation allows for a longer shelf life and improved texture in processed foods. However, trans fats have been shown to significantly impact heart health negatively.

They raise low-density lipoprotein (LDL) cholesterol, commonly referred to as "bad" cholesterol, while simultaneously lowering high-density lipoprotein (HDL) cholesterol, known as "good" cholesterol. This adverse effect on cholesterol levels can lead to an increased risk of heart disease, stroke, and other cardiovascular conditions.

Given these health implications, it is advisable to limit or completely avoid trans fats in the diet. The recognition of their detrimental effects has prompted public health agencies to recommend minimizing their consumption, leading to increased scrutiny and regulation of food products containing trans fats. Understanding their impact on cholesterol levels underscores why they should be avoided for maintaining overall health.
