Obesity is closely associated with metabolic disorders such as hyperglycemia and dyslipidemia. Leptin-deficient ob/ob mice (C57BL/6J-ob/ob) and C57BL/6J mice were randomly assigned to a diet of black rice with giant embryo (BR), white rice (WR), or AIN-93G (control) and pair-fed for 14 weeks. Although there was no significant difference in body weight, BR-fed ob/ob mice had (1) significantly lower body fat mass than WR- and control-fed ob/ob mice determined by dual-energy X-ray absorptiometry; (2) significantly lower blood glucose, serum insulin, and triacylglycerol levels than control-fed ob/ob mice; and (3) significantly lower liver weight, hepatic triacylglycerol, and hepatic lipid droplets than both WR- and control-fed ob/ob mice. Furthermore, DNA damage in the liver, determined by phosphorylated H2AX protein, and in the kidney, determined by single-cell gel electrophoresis, was significantly lower in BR-fed than WR- and control-fed ob/ob mice. This study indicates that BR ameliorates obesity and its related metabolic disorders.
