Which four nutrients should be fortified in human milk to meet the needs of rapidly growing premature infants?

• A. Protein, Calcium, Phosphorus, Sodium
• B. Vitamin A, Vitamin D, Iron, Zinc
• C. Carbohydrate, Water, Electrolytes, Vitamin K
• D. Protein, Iron, Zinc, Vitamin C

Answer: (A)

Rapidly growing preterm infants have much higher protein and mineral needs than term infants, and human milk alone often falls short in supplying those requirements. Fortifying human milk with protein to boost nitrogen intake alongside minerals essential for bone development—calcium and phosphorus—helps support rapid growth and proper skeletal mineralization. Sodium is included because preterm infants have higher needs for maintaining extracellular fluid balance and electrolyte stability as their kidneys mature and growth accelerates. Vitamins and trace elements like iron and zinc are important, but they are typically addressed through broader supplementation strategies rather than the primary fortification targets aimed at meeting the immediate growth and bone-mineral needs. Carbohydrates, fluids, electrolytes, and vitamin K are managed separately in standard infant feeding protocols.
