Clinical Nutrition is the study of how nutrients and dietary interventions impact human health, with a primary focus on the prevention, diagnosis, and management of disease. This course explores the principles of nutritional assessment, metabolic pathways, and the development of tailored nutrition care plans for diverse patient populations. Topics include the role of macronutrients and micronutrients in health and disease, nutritional therapy for specific medical conditions, the importance of evidence-based guidelines, and the integration of nutrition within interdisciplinary healthcare teams. Emphasis is placed on critical thinking, case-based learning, and application of nutritional science to clinical practice.
