| Outline of Final Research Achievements |
In this study, we used the diet containing acetylated, propionylated or butyrylated starches in order to increase the level of short-chain fatty acids (SCFA) in the intestinal lumen. As a result, the diet was good for the growth of mice and resulted in the creation of SCFA such as acetic acid, propionic acid or butyric acid in the cecum. We fed SPF mice with the diet and investigated physiological function. However, no definite behavior change was found between the mice group which did have SCFA containing diet and did not. In conclusion, this diet is considered to be useful for elucidating the mechanism by which SCFA derived from gut microbe affect host physiology.
