Data are expressed as the mean ± standard deviation (SD). The mean values on the same column with different lower-case superscripts and row with different upper-case superscripts represent significant differences () based on analysis of variance (ANOVA) and Duncan’s multiple range tests. CIB, cereal-based instant beverage; C1 to C3, group C subgroups, group A (diabetic control) fed with rat ration, group B treated with metformin and fed with rat ration, group C (C1, C2, and C3) fed diet loaded with 50%, 60%, and 70% of optimized CIB, respectively.
