Insights
This study found that infant formula with a new oligosaccharide mixture is safe and well-tolerated. It showed similar growth and fewer adverse events compared to standard formula, with softer stools resembling breast milk.
Area of Science:
- Pediatrics
- Nutritional Science
- Gastroenterology
Background:
- Oligosaccharides in infant formula aim to replicate human milk's benefits.
- Assessing tolerance and safety of novel oligosaccharide mixtures is crucial for infant nutrition.
- Human milk oligosaccharides (HMOs) play a vital role in infant gut health and immune development.
Purpose of the Study:
- To evaluate the tolerance and safety of an infant formula containing a unique oligosaccharide blend.
- To compare growth parameters, tolerance, and adverse events in infants fed with prebiotic versus control formula.
- To assess the impact of the novel oligosaccharide mixture on stool consistency and its similarity to breastfed infants.
Main Methods:
- Multi-center, randomized, double-blind, placebo-controlled trial.
- Inclusion of healthy term infants (<8 weeks old), both formula-fed and breastfed.
- Randomization to prebiotic formula (neutral and acidic oligosaccharides) or control formula; assessments at 8, 16, 24, and 52 weeks.
Main Results:
- Similar growth (weight, length, head circumference) and stool frequency between prebiotic and control formula groups.
- Prebiotic group showed softer stools, closer to the breastfeeding group, at 8, 16, and 24 weeks.
- No significant difference in adverse event incidence between the two formula groups.
Conclusions:
- The infant formula with the innovative oligosaccharide mixture is well-tolerated and safe for healthy infants.
- The prebiotic formula supports softer stools, indicating potential benefits for gut comfort.
- Long-term safety demonstrated in a large cohort of infants, supporting its use in infant nutrition.
Background:
the addition of oligosaccharides to infant formula has been shown to mimic some of the beneficial effects of human milk. The aim of the study was to assess the tolerance and safety of a formula containing an innovative mixture of oligosaccharides in early infancy.
Methodology/Principal Findings:
this study was performed as a multi-center, randomized, double-blind, placebo-controlled trial including healthy term infants. Infants were recruited before the age of 8 weeks, either having started with formula feeding or being fully breast-fed (breastfeeding group). Formula-fed infants were randomized to feeding with a regular formula containing a mixture of neutral oligosaccharides and pectin-derived acidic oligosaccharides (prebiotic formula group) or regular formula without oligosaccharides (control formula group). Growth, tolerance and adverse events were assessed at 8, 16, 24 and 52 weeks of age. The prebiotic and control groups showed similar mean weight, length and head circumference, skin fold thicknesses, arm circumference gains and stool frequency at each study point. As far as the anthropometric parameters are concerned, the prebiotic group and the control group did not attain the values shown by the breastfeeding group at any study point. The skin fold thicknesses assessed in the breastfeeding group at 8 weeks were strikingly larger than those in formula fed infants, whereas at 52 weeks were strikingly smaller. The stool consistency in the prebiotic group was softer than in the control group at 8, 16 and 24 weeks (p<0.001) and closer to that of the breastfeeding group. There was no difference in the incidence of adverse events between the two formula groups.
Conclusions:
our findings demonstrate the tolerability and the long term safety of a formula containing an innovative mixture of oligosaccharides in a large cohort of healthy infants.
