Abstract:
Objective: To investigate the specific effects of resistant starch (RS) on zinc status in rats. Methods: (1)Zinc metabolism in normal rats: Three groups of Wistar rats were fed with basal diet (control), diet with 13% or 26% RS respectively, for 18 days. Urine, fecal and blood samples were collected for zinc measurement. Zinc apparent absorption was calculated.(2)Zinc status in rats fed with high sucrose (50%) diet: Three groups of Wistar rats were fed with basal diet, high sucrose digestible starch diet (S DS) or high sucrose resistant starch diet (S RS, containing 14% RS) respectively for 12 w. Samples of urine, blood, liver, pancreas and kidney were collected for measurement of zinc content. Results: (1)Zinc apparent absorption in normal rats was: control group 56.59%, 13%RS group 50.11%, and 26%RS group 54.40%. (2)High sucrose diet led to increased postprandial glucose and HbA 1C and depressed fast insulin level in S DS group rats, with decreased plasma and pancreas zinc level (compared with control group, P
