1. Charakterystyka żywności / składnika
The food constituent that is the subject of the health claims is isomalto-oligosaccharides. Isomalto- oligosaccharides (IMO) are produced by enzymatic hydrolysis of starch and consist mainly of oligomers of isomaltose, panose, isomaltotriose and isomaltotetraose connected by non-digestible α 1→6 glucosidic linkages. IMO do not occur naturally in foods. IMO can be quantified in foods by established methods.
The Panel considers that the food constituent, isomalto-oligosaccharides, which is the subject of the health claims, is sufficiently characterised.

The claimed effect is “low glycaemic index”. The Panel assumes that the target population is 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.
Postprandial glycaemia is interpreted as the elevation of blood glucose concentrations after consumption of a food and/or meal. This is a normal physiological response that varies in magnitude and duration and may be influenced by the chemical and physical nature of the food or meal consumed, as well as by individual factors (Venn and Green, 2007). The evidence provided does not establish that decreasing post-prandial glycaemic responses in subjects with normal glucose tolerance is a beneficial physiological effect. However, it may be beneficial to subjects with impaired glucose tolerance as long as post-prandial insulinaemic responses are not disproportionally increased. Impaired glucose tolerance is common in the general population of adults.
The Panel considers that reduction of post-prandial glycaemic responses (as long as post-prandial insulinaemic responses are not disproportionally increased) may be a beneficial physiological effect.

Two references were provided for the scientific substantiation of this claim. One was in Chinese and unavailable to the Panel, and the second reported on an intervention study in dogs on post-prandial glucose concentrations (Hesta et al., 2001). The Panel considers that while effects shown in animal studies may be used as supportive evidence, human studies are required for the substantiation of a claim, and that the evidence provided in animal studies alone is not sufficient to predict the occurrence of an effect of isomalto-oligosaccharides consumption on the reduction of post-prandial glycaemic responses in humans.
The Panel concludes that a cause and effect relationship has not been established between the consumption of isomalto-oligosaccharides and reduction of post-prandial glycaemic responses.
