Background: Diabetes is one of the most common metabolic disorders and is related to oxidative-stress-induced diseases. Given the role of dietary antioxidants in the control and prevention of diabetes, this study aimed to examine the effects of sesame butter versus sesame oil on the serum levels of glucose, lipid profile, and oxidative stress biomarkers in diabetic rats.Methods: Forty male albino rats of Wistar strain were randomly divided into 4 groups (i.e., nondiabetic control rats, diabetic rats, diabetic rats treated with sesame butter, and diabetic rats treated with sesame oil). Experimental diabetes was induced with an intraperitoneal injection of streptozotocin (55 mg/kg). Sesame butter (1.25 g/kg) and sesame oil (0.5 g/kg) were given by oral gavage to the diabetic rats for 6 weeks. Finally, serum glucose, lipid profile, total antioxidant capacity (TAC), and malondialdehyde (MDA) levels were measured and analyzed statistically.Results: Our data showed that the diabetic groups treated with sesame butter and sesame oil had significantly lower levels of glucose and higher levels of high-density lipoprotein than did the diabetic control group at the end of the study (P<0.05). Sesame butter supplementation also increased TAC and decreased MDA concentrations significantly in the diabetic rats (P<0.05).Conclusion: The antihyperglycemic, antioxidative, and partly lipid-lowering effects of sesame butter make it an excellent candidate for future human studies on diabetes, although further research is needed to determine the exact dose and duration of supplementation.
