Nutrition and immune function

Abstract

The complexity of the immune system allows for a multitude of potential avenues for nutrient modulation, but this also increase the challenge of producing a predictable in vivo response. Because the immune response is a cascade of biologic events, development of nutritional support paradigms cannot and should not be made in a vacuum or with the expectation of a singular response. It is absolutely imperative that the clinician/nutritionist understand the differences in metabolIc and physiologic responses to disease states (ie, shock, trauma, organ-specific dysfunction) so as to maximize immunocompetence through specialized feeding practices. This level of understanding is invaluable, especially when considering the possible benefit of nutrient combinations for immunomodualtion.
