Area of Science:

  • Biochemistry
  • Pediatric Nutrition
  • Clinical Medicine

Background:

  • Ten trace elements are nutritionally essential for human health.
  • These include zinc, copper, selenium, chromium, manganese, molybdenum, cobalt, fluoride, iodine, and iron.
  • Understanding their roles is critical, especially in vulnerable populations like preterm infants.

Purpose of the Study:

  • To review the biochemistry of ten essential trace elements.
  • To describe clinical deficiency states associated with these elements.
  • To provide evidence-based recommendations for enteral and parenteral intakes in preterm infants.

Main Methods:

  • Literature review of biochemical functions.
  • Analysis of clinical data on deficiency symptoms.
  • Synthesis of current recommendations for infant nutrition.

Main Results:

  • Detailed biochemical roles of essential trace elements.
  • Clinical manifestations of trace element deficiencies.
  • Specific intake guidelines for enteral and parenteral nutrition in preterm infants.

Conclusions:

  • Trace elements are critical for preterm infant growth and development.
  • Appropriate enteral and parenteral nutrition strategies are essential to prevent deficiencies.
  • Further research may refine optimal intake levels for specific clinical situations.
