The type of dietary fat considered trans fat is artificially created through hydrogenation, which solidifies liquid oils. Found in many processed foods, such as baked goods, margarine, and snack foods, trans fats are linked to increased levels of bad cholesterol (LDL) and decreased levels of good cholesterol (HDL). Consuming trans fats raises the risk of heart disease and other health issues. Many health organizations recommend lowering or eliminating trans fat intake to improve overall health and protect cardiovascular function.
