composition of dietary fats

Composition of dietary fats

No dietary oil is purely saturated or unsaturated.  All natural fats and oils consist of a mixture of the three classes of fatty acids.  To say an oil is saturated or monounsaturated is a gross oversimplification in part.  Olive oil is often called ‘monounsaturated’ because it is predominantly monounsaturated, but like all vegetable oils, it also contains some polyunsaturated and saturated fats as well (see table for the amounts of each kind of fatty acid found in different fats and oils)
