Based on the definition of the European Food Safety Agency (EFSA), dietary fibre (DF) includes non-starch polysaccharides, resistant starch, resistant oligosaccharides with three or more monomeric units and other non-digestible, but quantitatively minor, components that are associated with the dietary fibre polysaccharides, especially lignin1. This definition is in accordance with Codex Alimentarius’ (CODEX) definition, although the inclusion of non-digestible carbohydrates with 3-9 monomeric residues is so far left of the natnow supplements zinc glycinateional authorities2. Examples of DF include cellulose, hemicelluloses, pectins, hydrocolloids, fructo-oligosacchamagnesium glycinate sunday naturalrides (FOS), galacto-oligosaccharides (GOS) or resistant starch.
