Medium-chain triglyceride feeding in premature infants: effects on fat and nitrogen absorption
Insights
Medium-chain triglycerides (MCT) significantly reduced stooling and improved fat absorption in premature infants. These findings suggest MCTs enhance nutrient absorption and nitrogen sparing in preterm babies.
Area of Science:
- Nutritional Science
- Pediatric Gastroenterology
- Neonatology
Background:
- Premature infants often experience "physiological" steatorrhea, characterized by poor fat absorption.
- This condition can impede growth and nutrient assimilation in vulnerable newborns.
- Identifying effective interventions is crucial for improving outcomes in preterm infants.
Purpose of the Study:
- To investigate the efficacy of medium-chain triglycerides (MCT) in managing steatorrhea in premature infants.
- To compare the effects of different MCT concentrations in infant formulas on fat and nitrogen absorption.
- To assess the impact of MCT on stool characteristics in preterm neonates.
Main Methods:
- A study involving 34 premature infants (birthweight < 2,000 gm) divided into three feeding groups.
- Group 1 (control) received a formula with corn oil, oleo, and coconut oil.
- Groups 2 and 3 received formulas with varying percentages of MCTs, corn oil, and coconut oil.
Main Results:
- Infants fed MCT-containing formulas exhibited a significant reduction in stool volume and frequency.
- Total fat absorption was markedly improved in infants receiving MCT-enriched formulas compared to the control group.
- A slight but significant improvement in nitrogen absorption was observed in the group fed 80% MCT formula.
Conclusions:
- Medium-chain triglycerides (MCT) are effective in ameliorating "physiological" steatorrhea in premature infants.
- MCT-containing formulas enhance fat absorption and potentially nitrogen sparing in preterm neonates.
- Dietary adjustments with MCTs represent a promising strategy for improving nutritional outcomes in premature infants.
Abstract:
The effect of medium-chain triglycerides (MCT) on the "physiological" steatorrhea of prematurity was studied in 34 infants with birthweights below 2,000 gm. The infants were divided into three groups and fed three formulas identical in nutrient content except for the type of fat, as follows: group 1 (control): corn oil, oleo, and coconut oil (39:41:20); group 2: MCT, corn oil, and coconut oil (40:40:20); group 3: MCT and corn oil (80:20). The infants fed MCT-containing formulas had striking diminution in stool volume and frequency. Their total fat absorption was significantly improved when compared with controls; nitrogen absorption was slightly but significantly improved in the 80% MCT group. The results also suggest that nitrogen sparing may be enhanced in premature infants fed MCT-containing formulas.
