Although bifidobacteria may have traits which are beneficial for human health, not all Bifidobacterium possess such traits. The results obtained from these studies introduced here indicate that the different residential features of bifidobacteria may be the results of adaptation to the diet and environment.

Complementing the law of nature, the capabilities of HRB, especially infant-type HRB, to utilize various glycans available in the human gut as well as their compatibility with human breast milk have drawn attention to the possibility that infant-type HRB could be a better candidate as probiotics for human health.

Morinaga Milk will continue research on bifidobacteria for better understanding of the mechanisms of residential features and superiority of HRB species for the contribution to human health.
