Decreased ability to digest and/or absorb nutrients! drug effects! diarrhea! vomiting! change need for nutrients:! some illnesses cause a hypermetabolic state - require more calories than non sick people ! because they have high metabolic rates! Higher protein - break down of protein to use for immune proteins ! Higher amino acid needs to synthesize immune protein ! carb and fat can be used for energy by immune cells! Polymeric (intact protein) all of the nutrients are intact. Boost or ensure! semi-elemental and elemental pre-digested and broken down to facilitate nutrient absorption ! In some gi disorders, have trouble absorbing nutrients.
