RESUMO
The effect of chromium administration on glucose utilization was investigated in 32 rats fed either high or low protein diet. In rats fed a low protein diet of NDpE% 4.3 the glucose removal rate increased significantly following the administration of chromium. However, the administration of chromium has no effect on the glucose removal rate in rats fed high protein diet of NDpE% 10.1. The glucose removal rate of rats kept on a diet of high protein value free from chromium was significantly higher than those kept on a low protein diet. Chromium deficiency did not appear to be the only responsible cause for the impaired glucose tolerance in animals fed low protein diet. It could be concluded that both chromium supplementation and protein ingestion promote insulin secretion.
