Outline of Final Research Achievements |
Objective of this study was to test the hypothesis that rice-derived alpha-glucan plays a role in health-promotion of Japanese people through modulation of host-defense system. Oral feeding with rice-derived starch significantly suppressed the development of nasal symptoms in a murine model of allergic rhinitis without affecting adaptive immunity. The anti-inflammatory effect was more potent in uruchi-rice than in mochi-rice, suggesting that a major anti-allergic alpha-glucan unit was amylose. I also found a possibility that one could modulate such anti-allergic potency by regulation of rice starch consumptions.
