The condition of the body is maintained at a constant level by modulating body temperature and blood pressure, to cope with changes in the environment inside and outside the body.

This mechanism is called homeostasis. In homeostasis, the innate immune system plays an important role: it eliminates foreign substances (non-self) such as pathogens, viruses and cancer cells. However, it is known that immune function deteriorates with aging, and is impaired or stimulated by a poor lifestyle such as smoking, insufficient physical exertion or an unbalanced diet, and by adverse environmental changes and pollution.

Deterioration of immune function causes or aggravates infection and malignant tumors, while excessive elevation of the immune system may cause things such as hay fever, atopic dermatitis or chronic inflammation.

Daiwa Pharmaceutical Co., Ltd. has focused on a dietary fiber thought to have the potential to impact the immune response and developed a multifunctional food slosely related to the Japanese foodstuff of ancient times, named BioBran (Rice Bran Arabinoxylan Compound). ・
