The aim of this study is to investigate the ameliorative potentials of Cyperus esculentus (Tigernut) oil, in type 2 diabetes induced with the combination of high fat diet and a low dose streptozotocin (35mg/kg) in male Wistar rats. Forty rats weighing between 100-115g were divided randomly into group of five (n=8), 3 groups were subsequently fed with a high fat diet (HFD) for 30 days and the other 2 were maintained on normal rat chow (NPD). Results revealed an increase in body weight amongst the groups fed with a HFD and treatment with C. esculentus oil significantly (P<0.05) reduced the body weight (HFD+STZ+CEO). Glycated hemoglobin (HbAIC), G6PDH and α-Amylase activity were significantly stabilized in C.esculentus oil treated group. Oral glucose tolerant test with a load dose of 150 mg/kg glucose showed there was a rapid blood sugar level clearance in HFD+STZ+CEO as compared to untreated group (HFD+STZ). Atherogenic index (AIP) levels was significantly (p<0.05) lowered in the treated groups (HFD+STZ+GLI 0.262±0.40 and HFD+STZ+CEO 0.18±0.03) when compared to untreated groups (HFD+STZ 0.495±0.66 and NFD+STZ 0.495±0.57) as well as Triglyceride and VLDL levels. Enzymatic antioxidants activities were enhanced by C. esculentus oil. Therefore, C. esculentus oil may be used as either a therapeutic agent or as a dietary choice for the management of type 2 diabetes.
