The effects of the soy protein and casein diets on mice were studied. Bifidobacteria, clostridia, and lactobacilli were fewer and the cecal β-glucuronidase activity was higher in the soy protein diet group. Equol was detected only in plasma from the soy protein diet group. These results indicate that the soy protein diet has an impact on the intestinal microflora.
