The intestinal microbiota of infants is a critical component in the development of digestive and immune functions. As the baby’s immune system continues to mature, the innate immune system takes most of its cues from the intestinal bacteria.
Current research indicates that a healthy infant microbiome is required to modulate Th1 and Th2 immune responses and promote the healthy production of secretory IgA, a critical immunoglobulin secreted into the lumen of the gut which is responsible for important non-inflammatory immune functions. These factors are all required for minimising the risks associated with the development of allergy and autoimmune diseases.
While providing healthy bacteria to the baby is necessary for proper colonisation of the gut, another important factor is an adequate supply of prebiotics. Prebiotics influence the composition and activity of the gastrointestinal microbiota, which in turn can have a major effect on the immune system that may be sustained throughout life. As well as this, prebiotics have been shown to be beneficial for the maturation of the infant gut, nutrient absorption and metabolism, resistance to pathogens and optimal digestive function.
In this infographic we explore the research that indicates that prebiotics, such as fructo-oligosaccharides (FOS) and galacto-oligosaccharides (GOS), play an important role in early nutrition and the impact of prebiotics on the development and modulation of the infant immune system.
