Comparison of diarrhea induced by ingestion of fructooligosaccharide Idolax and
disaccharide lactulose (role of osmolarity versus fermentation of malabsorbed carbohydrate).
«test meals consisting of sponge cakes made with rapidly digestible, nonfermentable amylopectin starch plus cellulose, amylopectin starch plus the fermentable
disaccharide lactulose, or slowly digestible, partly fermentable amylose starch plus cellulose.»
The purified fiber used for the LGI breakfast and for 1 of the 2 HGI breakfasts was a preparation of nonfermentable purified cellulose from hazelnut shells (ALSO, Zelbio, Italy), whereas, in the second HGI breakfast, the HGI - Lac meal, cellulose was replaced with 5 g of the undigestible and highly fermentable
disaccharide lactulose in crystalline form (INALCO, Milan, Italy).
In particular, the SME of a completely and rapidly digestible breakfast containing amylopectin starch with or without added the fermentable
disaccharide lactulose was compared with that of a slowly digestible breakfast meal containing high - amylose starch, in which, besides being slowly digested, some of the starch would escape small - intestine digestion and be fermented in the colon.
Not exact matches
We enhanced the colonic fermentation of an HGI amylopectin breakfast meal by adding
lactulose, a soluble
disaccharide that boosts colonic fermentation but that, because it is nonviscous, should not affect the GI of the food to which is added.
Lactulose, a non-metabolizable
disaccharide, acidifies colonic contents (causing ammonia trapping), shortens the intestinal transit time, alters colonic flora, promotes incorporation of ammonia into bacterial proteins, and reduces production of potentially toxic short - chain fatty acids (SCFA) by producing the nontoxic SCFA acetate.
