The low birth weight infant's (LBW) nutrition needs special attention. Energy requirements are increased due to a high metabolic rate and a low thermogenesis. Increased protein requirements are, easy to be absorbed (from lacto-serum). Lipids, as important energetic source requires an appropriate content in essential fatty acids and medium chain triglycerides (TGM) which are easy absorbed in absence of lipase and deficit of bile salt secretion. The carbohydrates should be represented by lactose or equivalents like di-, oligo or polysaccharides. The addition of maltodextrin avoid an exaggerate supply and incomplete digestion of lactose. Sodium requirement are increased due to exaggerated loss consequence of renal immaturity. The rapid rate of growth impose the addition of Calcium, Phosphorus, Iron, Copper, and vitamins, especially Vitamin D, E and Folic acid. The appropriate nutrition of LBW must cover his special needs to maintain the homeostasis and rapid growth. Precise nutrient requirements are, however, difficult to establish.
