| Outline of Final Research Achievements |
We examined the effects of indigestible saccharides including rare sugar D-allulose on a gut hormone GLP-1 secretion. Single oral administration of resistant maltodextrin (RMD) or D-allulose potently stimulated GLP-1 secretion in rats. D-allulose had larger and continuous stimulatory effect on GLP-1 secretion than RMD. The GLP-1-stimulating effect was observed by oral and luminal but not by intraperitoneal administration of D-allulose, indicating D-allulose exerted the effect in the intestinal lumen. These results demonstrate important role of enteroendocrine cell to sense indigestible saccharides in gut hormone secretions under a physiological condition.
