Figure 2  Glucose tolerance, insulin sensitivity and pancreatic islet size of mice. (A) Fasting serum glucose, (B) Fasting serum insulin, (C) Glucose concentrations during intraperitoneal glucose tolerance test (ipGTT), (D) ipGTT area under the curve (AUC), (E) Glucose concentrations during intraperitoneal insulin tolerance test (ipITT), (F) ipITT area under the curve (AUC), (G) Representative hematoxylin and eosin stained pancreatic islets (scale bars 100 um), (H) Islet size quantification of mice fed control diet (control), a high-fat diet (HF) or a high-fat diet with milk from goats fed a conventional diet (HFCD), from goats grazing (HFG) or from goats fed a CD supplemented with Acacia farnesiana pods (HFAF). Results are presented as the mean ± S.E.M., n = 6 mice per group and analyzed by one-way ANOVA followed by Tukey multiple comparison post hoc test. The differences were considered statistically significant at p < 0.05. Mean values with different lowercase letters show statistical differences between each other.
