Answer 1

The four types are unsaturated, saturated, poly saturated, and trans.

Unsaturated fats are the healthy ones and are liquid at room temperature. i.e. olive oil

Saturated and poly saturated fats are the bad ones, and they are solid at room temperature. i.e. butter

Trans fats are the worst of the lot, and are formed through industrial processes that turn the unsaturated fats into a form that is solid at room temperature. i.e. margarine or vegetable shortening
