FBGL: fasting blood glucose levels (F = 58.298, P < 0.05); PBGL: final postprandial blood glucose levels (F = 78.990, P < 0.05). a,b,cp < 0.05 significantly different from the diabetic group and b,c,d,ep < 0.05 significantly different from the control group. Groups with the same superscript letter did not represent any significant differences.
