Rice-bran products: phytonutrients with potential applications in preventive and clinical medicine

Abstract

This paper reviews phytonutrients from rice bran that have shown promising disease-preventing and health-related benefits in experimental research studies. Candidate products studied and under investigation include: inositol and related compounds, inositol hexaphosphate (IP6 or phytate), rice oil, ferulic acid, gamma-oryzanol, plant sterols, tocotrienols and RICEO, a new rice-bran-derived product. Diseases in which preventive and/or nutraceutical effects have been detected include: cancer, hyperlipidemia, fatty liver, hypercalciuria, kidney stones, and heart disease. In addition, rice-bran products may have potential applications as nutritional ingredients in the context of their utility in functional foods.
