Nutritional and metabolic care makes a difference in critical illness. Optimal nutrition can improve outcomes and complications with nutrition may do harm. The energy needs of critically-ill patients are controversial, and it is important to discriminate between this initial phase of critical illness and a more stable phase evolving into rehabilitation. Indirect calorimetry is very helpful to optimize the energy supply. It is repeatedly suggested that protein supply to critically-ill patients should be higher than to healthy individuals. There is, however, little evidence for this proposal, although it is a part of most guidelines. To consider nutritional failure, optimal nutrition should be defined. In critical illness more mechanistic research is needed to define optimal nutrition and metabolic care.
