The study looked at how cinnamon affects blood sugar and fat levels in diabetic rats. The researchers induced diabetes in rats and gave them different doses of cinnamon extract for 30 days. They found that the rats given high-dose cinnamon had lower blood sugar, total cholesterol, triglycerides, and LDL cholesterol levels, while their body weight and HDL cholesterol increased. This suggests that cinnamon could be a helpful spice for improving health in people with diabetes.
