Trans fats are a type of unhealthy fat that can be found in some processed foods. They are created through a process called hydrogenation, which turns liquid oils into solid fats. This process helps improve the shelf life and texture of products like margarine, baked goods, and fried foods. However, trans fats can raise bad cholesterol levels and lower good cholesterol levels, increasing the risk of heart disease. Many countries have implemented regulations to limit or ban the use of trans fats in food products. The World Health Organization recommends that people reduce their intake of trans fats to improve overall health. Reading food labels can help consumers identify and avoid products containing trans fats.
