Following an application from BENEO-Orafti S.A., submitted pursuant to Article 13.5 of Regulation (EC) No 1924/2006 via the Competent Authority of Belgium, the Panel on Dietetic Products, Nutrition and Allergies (NDA) was asked to deliver an opinion on the scientific substantiation of a health claim related to “native chicory inulin” and maintenance of normal defecation by increasing stool frequency. The food constituent that is a subject of a claim is “native chicory inulin”. The Panel considers that “native chicory inulin”, a non-fractionated mixture of monosaccharides (< 10%), disaccharides, inulin-type fructans and inulin extracted from chicory, with a mean DP ≥ 9, is sufficiently characterised in relation to the claimed effect. The Panel considers that maintenance of normal defecation by increasing stool frequency (provided that it does not result in diarrhoea) is a beneficial physiological effect. Six studies involving 86 subjects consistently showed that consumption of “native chicory inulin” at an amount of at least 12 g/day increases stool frequency. The Panel also notes the plausible mechanisms by which inulin and inulin-type fructans in “native chicory inulin” could exert the claimed effect. The Panel concludes that a cause and effect relationship has been established between the consumption of “native chicory inulin” and maintenance of normal defecation by increasing stool frequency. The following wording reflects the scientific evidence: “Chicory inulin contributes to maintenance of normal defecation by increasing stool frequency”. In order to obtain the claimed effect, 12 g of “native chicory inulin” should be consumed daily.
