[Abstract]
This study examined the effect of changing the proportion of dietary fat on metabolic control in rats rendered mildly diabetic with streptozotocin (STZ). The high-fat (HF) diet contained 66% energy as fat and 12% as carbohydrate while the low-fat (LF) diet contained 12% energy as fat and 66% as carbohydrate. Both diets had a P/S ratio of 1:3. Young male rats weighing 100 g were treated with STZ (60 mg/kg IV) and randomly allocated to either the LF of HF diet. After 2 weeks, the fasting plasma glucose concentrations were significantly higher in the HF-STZ rats than in the LF-STZ rats (13.2 +/- 1.2 mmol/L v 7.1 +/- 0.8 mmol/L, respectively, P less than 0.001). The increase in plasma glucose above the basal level following the intravenous glucose load (0.5 g/kg body wt) was similar in both groups of STZ-treated rats and glucose clearance was similarly impaired. The fall in glucose concentrations in the 30 minutes following the IV insulin (0.5 U Actrapid insulin/kg body wt) was greater in the LF-STZ rats (delta AUC = -1.60 +/- 0.20 mmol/L 0.5h) than in the HF-STZ group (delta AUC = -0.97 +/- 0.20 mmol/L 0.5 h, P less than 0.05) and either of the control groups (delta AUC = -0.94 +/- 0.37, -0.83 +/- 0.09 mmol/L 0.5 h for LF and HF rats, respectively, P less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)
