Immunonutrition，such as glutamine， arginine，ω-3 polyunsaturated fatty acids， dietary fiber and so on can improve the clinical outcome by supporting metabolism， enhancing immunologic function， suppressing excessive inflammatory response.

The purpose of the review is to describe some  known physiological mechanisms of immunonutrition and the consensus and argument on the clinical application of immunonutrition.
