Rice Components with Immunomodulatory Function

J Nutr Sci Vitaminol (Tokyo). 2019;65(Supplement):S9-S12. doi: 10.3177/jnsv.65.S9.


Rice (Oryza sativa) is one of the most important food crops in the world, and the effect of its consumption on human health is of great concern. Evidence has accumulated that rice contains several components, such as γ-oryzanol and rice bran fibers, which modulate the immune system. In addition, rice has other immunologically beneficial characteristics. It has a low allergenic potential and is gluten-free, reducing the risk of development of food allergies and diseases related to gluten sensitivity such as coeliac disease. This review presents the recent advances in our understanding of the immunomodulatory function of rice components.

Keywords: Immune modulation; allergy; inflammatory diseases; rice bran fiber; γ-oryzanol.
