Many packaged fast food products use hydrogenated oils, which are derived from vegetable fats, i.e., unsaturated fats in the liquid state of vegetable fats are hardened by hydrogenation and turned into solid or semi-solid fats and oils, with the aim of preventing deterioration of the fats and oils and enhancing the taste. The most common is vegetable butter, which is particularly harmful to children's growth and development.
