This study was designed to evaluate the effect of administration of chromium-enriched Grifola frondosa (CEGF) in insulin-resistant sucrose-fed mice. Mice were randomly assigned to be unsupplemented (S group) or to receive oral CEGF at a dose of 0.5, 1.0, 2.0, 3.0, 4.0, and 5.0 mg/kg per day chromium. A control group (C) did not consume sucrose and was not supplemented. Sucrose-fed mice had an elevated serum insulin concentration compared with controls and this was significantly lower in sucrose-fed mice that received CEGF (4.0 and 5.0 mg/kg per day chromium), which did not differ from controls. Impaired glucose tolerance in sucrose-fed mice, evidenced by the poor glucose disposal rate following an intraperitoneal glucose tolerance test, was significantly improved in mice receiving CEGF. CEGF is essentially nontoxic at the dose of 4.0 and 5.0 mg/kg per day. These results indicate that CEGF may have potential beneficial effects in insulin-resistant prediabetic conditions.
