Abstract

Effects of newly developed functional rice grains Goami (high-amylose rice) and Nokwon (green-kerneled rice) on the glucose metabolism and antioxidative defense system in C57BL/6N mice under high fat diet condition were investigated. Animals were randomly divided into five groups (n = 8) and given experimental diets for eight weeks: normal control diet (NC), high fat diet (HF), and high fat diet supplemented with white rice (HF-WR), Goami rice (HF-GR), and Nokwon rice (HF-NR). At the end of the experimental period, the HF group exhibited markedly higher blood glucose level, insulin concentration, plasma lipid peroxidation and lower hepatic glycogen concentration than that exhibited by NC group. However, diet supplementation of Goami and Nokwon suppressed the high fat diet-induced hyperglycemia and oxidative stress through inhibition of the glucose-regulating enzymes and enhancement of the antioxidant enzymes activities. The results illustrate that the new functional rice Goami and Nokwon may be useful in the development of functional foods with preventive effect against high fat diet-induced hyperglycemia and oxidative stress.
