Which fat type is not among the three listed?

• A. saturated fat
• B. monounsaturated fat
• C. polyunsaturated fat
• D. trans fat

Answer: (D)

Fats are commonly classified by the saturation of their fatty acids: saturated fats have no double bonds, monounsaturated fats have one double bond, and polyunsaturated fats have multiple double bonds. Those three cover the main categories based on saturation. Trans fats, while unsaturated, have a different arrangement around their double bonds (trans geometry) and aren’t included in that trio of main categories. They’re typically produced in processed foods and are associated with less healthy cholesterol effects, which is why they’re treated separately in nutrition guidelines. Therefore, the fat type not among the three listed is trans fat.
