What is trans fat made up of?

Trans fat is primarily made up of unsaturated fatty acids that have been chemically altered through a process called hydrogenation. This process involves adding hydrogen to liquid vegetable oils, converting them into solid or semi-solid fats. Trans fats can be found in partially hydrogenated oils, which are often used in processed foods, baked goods, and margarine. They are associated with increased risk of Heart disease and other health issues.
