Ms. C has been reading about trans fats in the media. She read that trans fats are monounsaturated fats that are used in margarine, snacks and baked goods to extent their shelf life
What she does not understand is the difference between trans-monounsaturated fats and cis-monounsaturated fats. The nurse responds by explaining that: 1. Trans-monounsaturated fats decrease LDL and increase HDL, whereas cis-monounsaturated fats decrease LDL and HDL.
2. Trans-monounsaturated fats increase both LDL and HDL, whereas cis-monounsaturated fats increase LDL and HDL.
3. Trans-monounsaturated fats increase LDL and decrease HDL, whereas cis-monounsaturated fats may mildly decrease or not effect LDL or mildly increase or not affect HDL.
4. Trans-monounsaturated fats decrease LDL but have no effect on HDL, whereas cis-monounsaturated fats decrease LDL but have no effect on HDL.

Rationale: The effect of monounsaturated fats depend if they are in the trans or cis configuration. Trans-monounsaturated fats increase LDL and decrease HDL levels, two negative effects. Cis-monounsaturated fatty acids may produce a mild decrease in LDL levels or have no effect, and produce a mild increase or have no effect on HDL levels.
