This study was performed to investigate the effects of rice added with mulberry leaves and fruit on blood glucose, body fat and serum lipid levels in Sprague-Dawley male rats for 4 weeks. Mulberry rice diet was prepared with mixture of 50% of purified AIN-diet and 50% of formulated rice consisting of soybean, barley, polished rice, black rice, uncleaned rice bud, mulberry leaves and fruit. The experimental animals were fed the mulberry rice diet (group A) and the purified AIN-diet (group B, diabetic control) for 4 weeks in rats injected with streptozotocin. In terms of observing hypolipidemic effect of mulberry rice, rats were fed either high-fat diet (13% fat) with additional lard, corn oil, cholesterol to AIN-diet (group C, control) or mulberry rice diet mixed with high fat diet (group D) for 4 weeks. Blood glucose level at the 4th week of group A had increased 5 ㎎/dL compared with that of day 0, while group B increased 51 mg/dL. However, the glucose levels of the groups A and B at the final day were 156 ㎎/dL (12.4% decrease compared with B) and 178 ㎎/dL, respectively. As for hypolipidemic effect, weight gain and body fat were 8% lower in the group D and serum triglyceride level also 19% lower in the group D compared with those of group C (p＜0.05).
