Hydrolyzed Proteins in Preterm Infants

摘要

Milk proteins are an essential component of the diet of preterm infants who have high requirements. Hydrolyzed proteins (HPs) have been introduced in infants'formulas (HPFs) to treat gastrointestinal disorders and to prevent allergic diseases. Several studies have evaluated the adequacy of HPs in preterm infants. Protein source significantly influences plasma amino acid concentrations. Protein utilization and efficiency are usually lower with HPFs compared to formulas with intact proteins. When protein intake is similar, a lower weight gain is generally observed with HPFs and a 10% increase in protein content is usually necessary to compensate for this reduction in protein utilization. Mineral absorption may also be reduced and no data exist for trace elements and vitamins.
