ABSTRACT

Diabetes mellitus is a chronic condition that significantly impacts global health, with an increasing prevalence largely due to lifestyle changes and poor dietary habits. Effective management of diabetes relies on a multifaceted approach that includes pharmacological treatment, physical activity, and, crucially, nutritional interventions. This comprehensive review explores dietary management strategies for diabetic patients, focusing on macronutrient distribution, carbohydrate management, micronutrient intake, functional foods, and emerging technologies. The review outlines the key nutritional goals for individuals with diabetes, including the regulation of blood glucose, lipid levels, and blood pressure, alongside the prevention of complications such as cardiovascular disease and kidney damage. Special attention is given to carbohydrate management through techniques such as carbohydrate counting and glycemic index/load, which help to stabilize blood glucose levels. Macronutrient considerations, including the roles of protein, fat, and dietary fiber in blood sugar control, are examined in detail, emphasizing the importance of high-quality fats, lean proteins, and fiber-rich foods. Micronutrients such as magnesium, chromium, and zinc, as well as omega-3 fatty acids, are discussed for their potential to enhance insulin sensitivity and support overall metabolic health. The role of functional foods, including cinnamon, fenugreek, and bitter melon, is reviewed for their promising effects on glycemic control, though further clinical research is needed. Additionally, the review addresses the influence of cultural and regional dietary patterns, highlighting the need for personalized dietary strategies that respect cultural food practices while promoting health. Challenges such as socio-economic constraints, limited access to nutrition education, and misinformation about dietary practices are also explored, along with emerging technologies that aim to improve dietary adherence. This review provides a comprehensive framework for the dietary management of diabetes, aiming to improve glycemic control and reduce the risk of long-term complications, with recommendations for future research and personalized dietary interventions.

Keywords: Diabetes mellitus, nutritional interventions, dietary management, glycemic control.
