Inulin-enriched diets increased insulin sensitivity. (A and B) STZ-treated and untreated mice at 11 weeks after STZ treatment were fasted for 5 hours; glucose was measured (A), and insulin sensitivity check index was calculated (B). (C–E) Mice without or with STZ treatment were fasted for 5 hours, injected IP with insulin at dose of 5 or 7.5 U/g body weight, respectively, and glucose was measured at indicated time points (insulin tolerance test [ITT]) (C and D); area under curve was calculated (E). (F–H) Five-hour fasted mice were administered with glucose (2 g/kg body weight) IP to measure glucose tolerance test (GTT) (F and G); area under curve was calculated (H).
