Serum glucose concentrations and area under the curve of glucose and insulin during oral glucose tolerance test (OGTT). Control, OVX rats fed a high-fat diet (HFD) with 1% dextrin; CFM, OVX rats fed an HFD with 1% lyophilized cauliflower mushroom; LFE, OVX rats fed an HFD with 0.1% L. fermentum plus 1% dextrin; CFLF, OVX rats fed an HFD with 1% CFM plus 0.1% L. fermentum; positive-control, OVX rats fed an HFD with 1% dextrin plus 30 μg/kg body weight 17β-estradiol. Changes of serum glucose concentration were measured during OGTT (a) and the average of the area under the curve (AUC) of glucose during the first part (0–40 min) and second part (40–120 min) of OGTT (b) was given. The changes of serum insulin levels were shown (c). Each dot and bar represents the mean ± SD (n = 12). Asterisk indicates significantly different among the treatments of OVX rats at p < 0.05. Different letters represent a significant difference in Tukey test at p < 0.05
