Insights
Supplementing infant formula with short-chain galacto- and long-chain fructo-oligosaccharides (scGOS/lcFOS) did not alter immune parameters in healthy infants. This study found no significant differences compared to standard formula or breastfeeding.
Area of Science:
- Pediatrics
- Immunology
- Nutrition
Background:
- The developing immune system in infants is crucial for long-term health.
- Infant milk formula (IMF) is a common alternative to breastfeeding.
- Prebiotics like short-chain galacto- and long-chain fructo-oligosaccharides (scGOS/lcFOS) are added to some formulas to modulate gut microbiota and potentially immune responses.
Purpose of the Study:
- To investigate the effect of IMF supplemented with scGOS/lcFOS (9:1 ratio) on basal immune parameters in healthy term infants.
- To compare the immune profiles of infants fed supplemented IMF versus standard IMF and breast milk.
Main Methods:
- A double-blind, randomized, placebo-controlled study involving 215 healthy term infants.
- Infants received either breast milk or IMF with or without scGOS/lcFOS.
- Serum immunoglobulins, lymphocyte subpopulations, and cytokines were analyzed at 8 and 26 weeks of age.
Main Results:
- No significant differences in measured immune parameters were observed between the IMF groups (with or without scGOS/lcFOS) at 8 and 26 weeks.
- The study included a breastfed group as a reference, with 187 infants completing the study.
- The supplementation of IMF with scGOS/lcFOS did not alter basal immune parameters compared to standard IMF or exclusive breastfeeding.
Conclusions:
- Supplementation of infant formula with a mixture of prebiotic oligosaccharides (scGOS/lcFOS) does not appear to affect the basal immune system development in healthy infants during the first six months of life.
- These findings suggest that the inclusion of scGOS/lcFOS at the tested concentration does not significantly modulate key immune markers in a generally healthy infant population.
Abstract:
This double-blind, randomized, placebo-controlled study, aimed to explore the effect of an infant milk formula (IMF) with 6 g/l short-chain galacto- and long-chain fructo-oligosaccharides (scGOS/lcFOS, ratio 9:1) on basal immune parameters in 215 healthy, term infants during the first 26 wk of life. After birth, the infants received breast milk or were randomized to receive an IMF with or without scGOS/lcFOS. Blood samples were collected at the age of 8 wk and 26 wk for the analysis of serum immunoglobulins, lymphocyte subpopulations, and cytokines. The scGOS/lcFOS group and the control group were compared in the statistical analysis. A breast fed group was included as a reference. In total, 187 Infants completed the study. No significant differences were observed between both formula groups in the different studied immune parameters at weeks 8 and 26. This explorative study indicates that supplementation of infant formula with a mixture of prebiotic oligosaccharides did not change the basal level of the measured parameters of the developing immune system in healthy infants with a balanced immune system during the first 6 months of life in comparison to feeding a standard infant formula and in comparison to exclusive breastfeeding.
