Evaluation of the Anti-diabetic Activities of Colored Rice Varieties in Streptozotocin-Induced Diabetic Rats -

The study was done to evaluate the replacement of white rice with other varieties of pigmented rice in a streptozotocin (STZ) -induced type 1 diabetic rat model (T1DRM). Application was carried out for a month in the form of ethanol extracts delivered via oral intubation or supplementation of whole-grain rice as 20% of the feed. The antioxidant activities of different colored rice varieties were measured, with the highest activity recorded in brown rice, followed by black, and then red rice. The results obtained for the T1DRM indicated that there had been a gain in body weight in all rats that received rice supplementation, with the highest seen in groups given diets supplemented with 20% red rice, while the lowest was in those supplemented with white rice. It was noted that the black and brown rice, either in extract form or 20% whole rice supplementation (P
