Effects of extruded polished rice, brown rice, and germinated brown rice supplemented with nacl on the blood pressure and adipocytokines of spontaneously hypertensive rats (SHR/Izm)

Abstract

We investigated the effects of extruded polished rice, brown rice, and germinated brown rice supplemented with NaCl on the blood pressure and glucose metabolism-related hormones of spontaneously hypertensive rats (SHR/Izm). Compared to baseline levels, no significant increase in systolic blood pressure was observed after intake of germinated brown rice for 13 weeks. Although plasma glucose concentrations did not significantly differ between dietary groups, the plasma C-peptide concentration was significantly lower in rats in the germinated brown-rice group than in rats in the other two groups. These results suggest that intake of germinated brown rice may suppress increases in blood pressure associated with NaCl intake and also improve insulin sensitivity.
