Nutrition therapy is a cornerstone of diabetes management, supporting glycemic control, weight management, and overall metabolic health. Individualized meal planning considers calorie needs, macronutrient distribution, glycemic index of foods, and cultural preferences to optimize dietary adherence. Evidence-based interventions, including carbohydrate counting, fiber-rich diets, and balanced macronutrient intake, help stabilize blood glucose levels and reduce the risk of complications. Functional foods, fortified products, and plant-based options can further enhance nutritional quality and promote cardiovascular health. By integrating personalized nutrition therapy into diabetes care, healthcare providers empower patients to make informed dietary choices, improve metabolic outcomes, and maintain long-term health and quality of life.
