Abstract
Traditional management of T2D involves lifestyle interventions, such as dietary modifications, increased physical activity, and weight management. The hygienic-dietary measures, particularly the diet, represent the first pillar of diabetes management. In the framework of our work, we conducted a study whose aim was to evaluate the effect of a diet enriched with Cinnamomum cassia on the equilibrium of diabetic patients followed at the Yaoundé General Hospital and at the Yaoundé National Centre for Diabetology and Hypertension. The study was a 12-week, parallel-design, randomized controlled trial (n = 34 Intervention Group (IG), n = 34 Control Group (CG); non-randomized open-label clinical trial with 2 arms lasting 4 months from May to August 2022. Patients were included if they had type 2 diabetes and the HbA1c value between 7%-8.5%. It was carried out in two groups: an experimental group and a control group whose patients were followed for a period of 12 weeks. At the beginning and at the end of the study, we recorded their HbA1c and then determined their level of adherence to the diet by a modified score. Patients in the experimental group were given a diet detailing the different types of food to be favoured in 07 categories: starchy foods, vegetables, fruits, fish, meats, dairy products and beverages, all associated with 100g of ground cinnamon and a 3g pod to be consumed ad libitum throughout the intervention period, as well as telephone calls as a reminder 1 times/week, while participants in the control group were given only the diet. In total we recruited 32 participants in both the experimental and control groups. The glycaemic control of both groups at baseline was 7.7 (7.12-8.37) and 7.85 (7.3-8.5) for the control and experimental groups respectively. At the end of the intervention we noted a decrease in HbA1c of 1.8% in the control group and a significant decrease of 3.6% in the experimental group (p=0.031) although there was an average adherence to the diet in both groups. This study shows that a diet enriched with Cinnamomum cassia improves glycaemic balance and significantly reduced HbA1c in intervention group compared to control group. This effect can be improve if the recommended dietary measures are strictly adhered to.if the recommended dietary measures are strictly adhered to.
