Abstract
The present studies aimed to evaluate the glycaemic and insulinaemic responses, in healthy adults, to short-chain fructo-oligosaccharides (scFOS) from sucrose used to replace sugars in foods. Two study populations aged 18-50 years were recruited and they consumed dairy desserts or pound cakes containing either standard sugar content or scFOS to replace 30% of the sugar content. For each study, the two products were tested once under a double-blind and cross-over design with at least 7d between the two tests. Glucose and insulin were measured using standard methods in blood samples collected with a venous catheter for 120min during a kinetic test. For the dairy desserts, replacing 30% of the sugars with scFOS significantly reduced postprandial glycaemic (AUC0-120min; P=0·020) and insulinaemic (AUC0-120min; P=0·003) responses. For the pound cakes, the glycaemic response was not altered (AUC0-120min; P=0·322) while the insulinaemic response tended to be lower (AUC0-120min; P=0·067). This study showed that scFOS can be used to replace sugars with the benefit of lowering the postprandial glycaemic response without increasing the insulinaemic response. The effect might be modulated by other parameters (e.g. fat content) of the food matrices.

As an example of dietary fibres, short-chain fructo-oligosaccharides produced from sucrose by a controlled reaction with the enzyme fructo-furanosiadase are not extensively digested nor absorbed in the small intestine, but as prebiotic fibres they will be selectively fermented in the large intestine, providing potential health benefits for the host[1]
More recently the effects of different mixtures of maltitol and short-chain fructo-oligosaccharides (scFOS) in dairy desserts on the postprandial blood glucose response were studied as a secondary objective in a Abbreviations: AUC0–120 min, AUC between 0 and 120 min; Cmax, maximum concentration; mITT, modified intention-to-treat; PP, per protocol; scFOS, short-chain fructooligosaccharides
