Outline of Final Research Achievements

Soy isoflavone and plant lignan are belong to the phytoestrogens. In this study, we found that the administration of equol-producing bacteria to the mice fed the diet containing daidzein and plant lignan increased the equol production as compared to the mice administrated physiological saline. Co-administration of three lignan-metabolizing bacteria and two isoflavone-metabolizing bacteria to the mice increased the enterodiol production as compared to the mice administrated physiological saline. Our results suggest that the administration of lignan-metabolizing bacteria to the mice fed the diet containing daidzein and plant lignan affects the lipid metabolism of mice differently from the administration of lignan-metabolizing bacteria plus isoflavone-metabolizing bacteria to the mice fed the diet containing daidzein and plant lignan.
