Additionally, different types of cinnamon have been found to inhibit digestive enzymes, with Chinese cinnamon showing strong activity against α-amylase, and all types potently inhibiting α-glucosidase activity.
Furthermore, clinical trials have demonstrated the potential of cinnamon to improve blood glucose levels in individuals with type 2 diabetes. Studies have shown that daily administration of cinnamon resulted in significant reductions in fasting plasma glucose (FPG) levels, HbA1c levels, and improvements in lipid profiles [2]. These findings suggest that the chemical composition of cinnamon plays a crucial role in its potential to stabilize blood sugar levels and positively impact overall health.
6. Mechanisms of Action in Blood Sugar Regulation
In understanding how cinnamon influences blood sugar regulation, it’s essential to delve into the mechanisms of action involved. Studies have shown that cinnamon extract enhances glucose uptake in adipocytes and myocytes by inducing LKB1-AMP-activated protein kinase signaling [1]. Additionally, cinnamon may affect blood glucose levels by influencing the insulin-signaling pathway, insulin receptor phosphorylation, and the translocation of glucose transporter GLUT4 [2]. Furthermore, the spice has been found to increase the level of glucagon-like peptide 1, inhibit intestinal α-glucosidase, inhibit gluconeogenesis, stimulate glycogen synthesis, and potentially delay gastric emptying, all of which contribute to the reduction in post-prandial blood glucose. These mechanisms shed light on how cinnamon’s components interact with the body to potentially impact blood glucose levels.
7. Clinical Studies on Cinnamon and Blood Sugar
Numerous clinical studies have been conducted to investigate the impact of cinnamon on blood sugar levels, particularly in individuals with type 2 diabetes. These studies have largely focused on cinnamon’s potential to improve insulin sensitivity, lower fasting blood glucose levels, and reduce HbA1c, a key marker of long-term blood sugar control. For example, a randomized, placebo-controlled clinical trial conducted by Salih Sahib [2] revealed that patients who consumed cinnamon experienced significant reductions in fasting plasma glucose, HbA1c, and total cholesterol compared to those who received a placebo. This suggests that cinnamon may be effective as a complementary treatment for managing blood sugar in diabetic patients.
Another notable study by Medagama [1] reviewed the experimental evidence and clinical trials surrounding cinnamon’s glycaemic outcomes. The study found that cinnamon not only improved glycaemic control but also had a positive effect on lipid profiles, potentially reducing cardiovascular risk factors in patients with type 2 diabetes. However, the study also highlighted the need for further research, as there are still controversies surrounding the appropriate dosage, duration of treatment, and the species of cinnamon that yields the most significant benefits.
