Indigestible dextrin equals to resistant dextrin
Dextrins are a type of starch, and as the name suggests, indigestible dextrin resists digestion. The other name of resistant dextrin is indigestible dextrin. Dextrin is made from cornstarch that is roasted and then hydrolyzed by amylase (an enzyme that digests starch taken in as food). Indigestible dextrin is a water-soluble dietary fiber extracted and prepared from the indigestible components in the resulting mush.
Dextrin was created with the aim of supplementing dietary fiber, which tends to be deficient in many diets. The aqueous solution of dextrin, which has low viscosity and low sweetness, is a food ingredient that is nearly transparent with excellent heat and acid resistance.
Indigestible dextrin is made from corn, and is used in supplement foods designed to prevent dietary fiber deficiency.
It is also approved as a functional ingredient of 'food for specified health use' by the Consumer Affairs Agency (Japan).
How resistant dextrin suppresses post-meal blood sugar rise?
One main function of the indigestible dextrin is slowing sugar absorption or suppressing post-meal blood sugar rise.
Sugars taken in from food are broken down into glucose inside the body. In several trials on sugars conducted in rats and humans, indigestible dextrin, along with monosaccharides and disaccharides, was confirmed to have no effect on monosaccharides such as glucose and fructose while it did act to suppress blood sugar rise caused by maltose.
Indigestible dextrin suppresses the rise of blood sugar after meals by inhibiting the digestion of maltose.
Further, human studies in which indigestible dextrin was taken together with meals confirmed that it suppresses the rise of blood sugar after eating.
Other main functions if indigestible dextrin:
Intestinal healing effect
Slows fat absorption (suppresses post-meal triglyceride rise in the blood)
Reduction of visceral fat
Promotion of mineral absorption
