A useful choice depends on at least four questions: fatty-acid profile, cooking conditions, flavor, and how often you use the oil.

The food matrix can affect how fat is released and consumed. Whole nuts are a good example: part of their oil remains trapped inside plant cell structures, and they also provide protein, fiber, minerals, and phytochemicals.
