Scientific Opinion on the substantiation of health claims related to isomalto-oligosaccharides and reduction of post-prandial glycaemic responses (ID 798), and increase in the frequency of daily bowel movements (ID 800) pursuant to Article 13(1) of Regulation (EC) No 1924/2006

Summary

Following a request from the European Commission, the Panel on Dietetic Products, Nutrition and Allergies was asked to provide a scientific opinion on a list of health claims pursuant to Article 13 of Regulation (EC) No 1924/2006. This opinion addresses the scientific substantiation of health claims in relation to isomalto-oligosaccharides and reduction of post-prandial glycaemic responses, and increase in the frequency of daily bowel movements. The scientific substantiation is based on the information provided by the Member States in the consolidated list of Article 13 health claims and references that EFSA has received from Member States or directly from stakeholders.

The food constituent that is the subject of the health claims is isomalto-oligosaccharides. The Panel considers that isomalto-oligosaccharides is sufficiently characterised.

Reduction of post-prandial glycaemic responses

The claimed effect is “low glycaemic index”. The target population is assumed to be individuals willing to reduce their post-prandial glycaemic responses. In the context of the proposed wording, the Panel assumes that the claimed effect refers to the reduction of post-prandial glycaemic responses. The Panel considers that the reduction of post-prandial glycaemic responses (as long as post-prandial insulinaemic responses are not disproportionally increased) may be a beneficial physiological effect.

No references were provided from which conclusions could be drawn for the scientific substantiation of the claimed effect.
On the basis of the data presented, the Panel concludes that a cause and effect relationship has not been established between the consumption of isomalto-oligosaccharides and the reduction of post-prandial glycaemic responses.

Increase in the frequency of daily bowel movements

The claimed effect is “normal bowel function/gastrointestinal function/colonic function”. In the context of the clarifications provided by Member States, the Panel assumes that the claimed effect is related to an increase in the frequency of daily bowel movements. The target population is assumed to be individuals with constipation. The Panel considers that an increase in the frequency of daily bowel movements within the normal range might be a beneficial physiological effect.

No human studies were provided from which conclusions could be drawn for the scientific substantiation of the claimed effect.

On the basis of the data presented, the Panel concludes that a cause and effect relationship has not been established between the consumption of isomalto-oligosaccharides and an increase in the frequency of daily bowel movements.
