Low fat butter is a type of food product designed to reduce the amount of fat in foods and lower the total dietary fat intake. It is also known as a butter substitute that is low in cholesterol, trans fats, saturated fats, and sodium. There are different forms in which low-fat butter is available, including margarine.
Margarine is made from vegetable oil, such as soybean oil or corn oil, which is processed into a spreadable form by hydrogenation. However, some unsaturated fats in the oils can be converted to saturated fats during hydrogenation, making it important to choose margarine products that are low in saturated fats.
