Influence of prebiotics on the human immune system (GALT).

Prebiotics have great potential to improve human health in specific intestinal disorders. The knowledge about the influence of prebiotics on the gut-associated lymphoid tissues (GALT) for the improvement of human health is still growing. This paper reviews the latest evidence for the immunity-enhancing effects of prebiotics. Prebiotics, include inulin, fructooligosaccharides, mannosoligosaccharides, and arabinogalactans, are a therapeutic nutritional preparation used for the gut function favoring growth of normal bacterial flora and impedes growth of pathogenic organisms. There is convincing preliminary data to suggest that the consumption of prebiotics can modulate immune parameters in GALT, secondary lymphoid tissues and peripheral circulation. There is increasing evidence that the newly described prebiotics and innovative means of administration can modulate various properties of the immune system, including those of the gut-associated lymphoid tissues (GALT). Authors of recently published patents showed new mechanisms for immuno-modulation, and the ultimate impact on immunological health of prebiotics.
