The global prevalence of diabetes is increasing gradually requiring effective intervention to be implemented. Inadequate nutritional management and lifestyle management contribute to the development of diabetes and its associated complications. To address this issue, dietary interventions are required to be formulated and implemented to control, reduce, and prevent the occurrence of diabetes across the globe. This systematic review study aims to analyze the impact of nutritional intervention on biomarkers among patients with diabetes. This cross sectional study aims to examine the impact of nutritional interventions on biomarkers in diabetic patients in a defined clinical population. Data were collected from diabetic patients who underwent structured nutritional interventions, and key biochemical markers were measured. Results indicate significant improvements in biomarkers following dietary adjustments, suggesting nutritional interventions' role in better managing diabetes.
