A low-glycemic available carbohydrate composition of the invention contains the following components: (i) 5-60 wt. % of one or more monosaccharides selected from monosaccharides other than glucose and fructose, in particular galactose, ribose and mannose; (ii) 15-95 wt. % of oligosaccharides having a length of 2 to 20 anhydromonose units, at least half of which are anhydroglucose units linked by non-α-1,4 bonds; these oligosaccharides preferably comprising disaccharides such as palatinose, isomaltose and trehalose and/or non-α-1,4 linked higher glucose-containing oligosaccharides; (iii) 0-45 wt. % of other available carbohydrates, such as glucose and maltodextrins. This carbohydrate composition can be part of a food composition for the treatment of diabetes, obesitas, insulin resistance, or for postprandial glucose response.
