All infections no matter how mild decrease nutrient intakes and increase nutrient losses even when subclinical. The losses include decreased intestinal absorption, direct loss of nutrients in the gut, internal diversion for metabolic responses to infection and increased BMR when fever is present. Infection influences in this way not only protein and energy status but also that of most other nutrients. The clinical importance of these consequences of infection depends on the prior state of the individual, the nature and duration of the infection and the diet of the individual during the infection, particularly dietary intake during the convalescent period and whether full recovery takes place before another infection occurs. In industrialized countries particular attention must be paid to the nutrition of hospitalized patients since they are frequently debilitated by their primary disease, morbidity, and their nutritional status. Morbidity and mortality are increased by nosocomial infections to which the poorly nourished individual is more susceptible.
