Full Answer

According to Mayo Clinic, trans fat is made when vegetable oil undergoes a process of hydrogenation, which makes it less likely to go bad. This helps foods that contain trans fat to stay fresh, have a longer shelf life and feel less greasy. It is thought that adding the hydrogen to the oil makes the oil harder to digest.

According to WebMD, the FDA would like to ban companies from using artificial trans fats without special permission. This ban would not include natural trans fats that may be found in beef, lamb and full-fat dairy products. Trans fats may be listed on food as "partially hydrogenated oils" instead of trans fat. When purchasing food, check the Nutrition Facts and the ingredient list. Even if the Nutrition Facts label claims the product has "0g trans fat," it can still have up to half a gram of trans fats per serving. If the ingredients list contains "partially hydrogenated oils," then the product contains trans fats.
