HUMAN NUTRITION

Detailed explanation-1: -Trans fatty acids (TFAs) are unsaturated fatty acids that contain at least one double bond in the trans configuration (Fig. 1). Trans fatty acids are formed during industrial partial hydrogenation of vegetable oil, a process widely commercialized to produce solid fats.

Detailed explanation-2: -Most trans fats are formed through an industrial process that adds hydrogen to vegetable oil, which causes the oil to become solid at room temperature. This partially hydrogenated oil is inexpensive and less likely to spoil, so foods made with it have a longer shelf life.

Detailed explanation-3: -Most of the trans fat in the foods we eat is formed through a manufacturing process that adds hydrogen to vegetable oil, which converts the liquid into a solid fat at room temperature. This process is called hydrogenation.
