Dietetics, the application of nutritional science to human health, has evolved significantly in the past 50 years. Today, dietitians are recognized experts in planning and assessing nutritional treatment for patients and the general public. They hold the unique ability to analyse, diagnose, and address diet and nutrition concerns, playing a crucial role in individual and societal well-being. By utilizing the latest insights on diet, health, and disease, dietitians offer practical guidance for improving overall health. However, certain dietary deficiencies like iron (Fe) and zinc (Zn) pose significant global health risks, impacting over 2 billion individuals and leading to malnutrition. As this field rapidly advances, medical and dietetic professionals must enhance their knowledge of safety, therapeutic effectiveness, and stay current in this dynamic domain.
