The type of fat typically considered unhealthy is trans fat. Found in many processed foods, trans fats can increase low-density lipoprotein (LDL) cholesterol levels while lowering high-density lipoprotein (HDL) cholesterol levels, increasing the risk of heart disease and stroke. Trans fats are often created during food processing through the hydrogenation of oils. Limiting or eliminating trans fat intake is crucial for maintaining cardiovascular health and overall wellness. Foods often high in trans fats include baked goods, snack foods, and margarine.
