Outline of Final Research Achievements

This study demonstrated that consumption of lily bulb, a traditional food in Asia, increased fecal IgA and mucins (indices intestinal immune and barrier functions), colonic fermentation, and improved intestinal microflora composition in rats fed a high-fat diet. Dietary lily bulb also reduced adipose tissue weight by increasing fecal lipid excretion. Furthermore, this study showed that consumption lily bulb may suppress liver injury and inflammatory colitis. These results suggest that lily bulb can be considered as a novel functional food for improving colonic luminal environment and preventing lifestyle-related diseases under the high-fat diet condition.
