*Molecular Impact of Dietary Fibre Metabolites on Intestinal Immunity of Host DOI: http://dx.doi.org/10.5772/intechopen.107348*

Pectin, a soluble dietary fiber with recognized modulatory effects on the gastrointestinal immunological barrier, is an essential dietary fiber. Because pectins have a positive influence on microbial communities, they may indirectly look after the intestinal barrier by increasing the growth and diversity of microbiota communities. The chemical structure of pectins has an immense impact on these actions. The well-studied prebiotics include inulin, oligofructose, and fructo-oligosaccharide (FOS). All β (2–1) linear fructans with varying degrees of polymerization are referred to as inulin. Inulin is not digestible by digestive enzymes in the small intestine due to the existence of β (2–1) bonds it enters the colon intact, where it is fermented to SCFA and gases by colonic bacteria. The well-studied prebiotics include inulin, oligofructose, and fructo-oligosaccharide (FOS). Moreover, commensal communities stimulated by dietary fiber are important taking into account, intestinal immunity. The microbial community secretes metabolites such as secondary bile acids and tryptophan, which together limit the growth of pathogens.
