Fermentation products: immunological effects on human and animal models

Area of Science:

• Microbiology
• Immunology
• Pediatrics

Background:

• Infant formulas impact gut microbiota development.
• Fermented milk-based formulas offer a novel approach to modulate gut immunity and microbiota.
• These formulas undergo fermentation with lactic acid bacteria and heat treatment, yielding specific products without viable bacteria or added prebiotics.

Purpose of the Study:

• To review the effects of fermentation products in milk-based infant formulas on the immune system.
• To differentiate the impact of fermentation products from that of live bacteria and prebiotics.
• To explore the potential of fermented formulas in establishing immune balance and oral tolerance in infants.

Main Methods:

• Literature review of in vitro and in vivo studies.
• Analysis of research on fermented milk-based infant formulas.
• Focus on the role of fermentation-derived compounds.

Main Results:

• Fermentation products may modulate gut microbiota composition.
• Specific fermentation products show potential in promoting immune balance and oral tolerance.
• Studies suggest active participation of fermentation products in immune modulation.

Conclusions:

• Fermented milk-based infant formulas, distinct from probiotic/prebiotic options, warrant further investigation.
• Fermentation products show promise for infant immune development and gut health.
• Additional research is needed to confirm clinical benefits and identify active compounds and pathways.
