Abstract The effect of supplementation with Phellinus linteus (P. linteus), Paecilomyces tenuipes (P. tenuipes), and Cordyceps militaris (C. militaris) mushroom water extracts on the insulin secretion and insulin resistance of 90\% pancreatectomized (Px) male Sprague Dawley rats was investigated. Px rats were daily administered 0.5 g of P. linteus, P. tenuipes, and C. militaris aqueous extracts or a placebo per 1 kg body weight with a 40\% fat diet for 8 weeks. Fasting serum glucose levels were lower in rats receiving C. militaris than in the control group. Insulin secretion at the elevated serum glucose levels was lowest in rats that consumed P. tenuipes in hyperglycemic clamp. Whole body glucose disposal rates increased in C. militaris but decreased in P. tenuipes compared to those in the control group in euglycemic hyperinsulinemic clamp. The GLUT4 content and fraction velocity of glycogen synthase in the soleus and quadriceps muscles increased in the rats treated with C. militaris, but P. tenuipes decreased both. In sum, a water extract of C. militaris ameliorates insulin resistance by enhancing glucose utilization in skeletal muscles.
