The Effect of Cinnamon-Based Cookies on Blood Glucose and Antioxidant Levels of ST-Induced Diabetic Rats

Introduction: Diabetes mellitus is a significant public health concern as its global prevalence continues to rise. Non-pharmacological treatments may offer promising results for diabetic patients. This study aimed to evaluate the effects of cinnamon-based cookies on blood glucose and antioxidant levels in diabetic rats. Methods: A randomized block design was used, involving five groups: a non-diabetic group, a positive control group receiving 0.6 mg/kg/day of glibenclamide, a negative control group receiving aqua dest, a group receiving cinnamon extract cookies (0.2 g/kg), and a group receiving powdered cinnamon cookies (0.6 g/kg). A total of 40 Sprague-Dawley rats were randomly divided into these groups (n = 8 per group). Diabetes was induced using streptozotocin (50 mg/kg). The intervention lasted for 21 days, during which body weight and blood glucose levels were monitored on days 0, 3, 7, 14, and 21. At the end of the intervention, the rats were sacrificed, and blood serum was collected via intracardiac puncture. Body weight was measured using a digital scale, while blood glucose levels were determined using a glucometer. The serum was then analyzed for SOD, MDA, and insulin levels using the ELISA method. Results: The study demonstrated that both types of cinnamon cookies significantly decreased blood glucose levels by day 3, with the cinnamon powder cookies achieving levels comparable to those of non-diabetic rats by day 7. Additionally, both types of cookies significantly improved SOD and insulin levels and reduced MDA levels in the rats. However, the body weight of the diabetic rats was not fully restored. Conclusion: These findings suggest that cinnamon could be utilized in food product development for blood glucose control, with cinnamon powder potentially offering more favorable results. conclusion: These findings suggest that cinnamon could be utilized in food product development for blood glucose control, with cinnamon powder potentially offering more favorable results.
