Outline of Final Research Achievements |
The objective of this study was to detect any immunological responses that may be enhanced in aged or young mice by consuming fermented dietary products such as natto. When mice were administered natto, low levels of IgA and IgG were seen in both young and aged mice. However, inductions of murine β-defensin specific mRNA were detected in the gum of both young and aged mice fed natto. In addition, the intestinal flora showed an increase of Clostridium subcluster XIVa, and the presence of butyrate as a metabolic product was confirmed. These results suggest that eating natto activates oral immunological responses and contributes to a healthy increase in beneficial gut flora.
