In a seriously ill patient, addition of amino acids indiet results in a positive nitrogen balance. The mechanism for this is :
Increased secretion of insulin Amino acid diet (paicularly arginine & lysine) stimulate insulin release which has anabolic effect on metabolism. It decreases protein catabolism .for energy and increases amino-acid uptake & protein synthesis.
Increased Growth hormones secretion
Enhanced rate of gluconegenesis
Increased absorption of amino acids from diet
Increased secretion of Insulin.
