Dietetics is the science of applying principles of nutrition to the planning and preparation of meals in order to improve overall health and well-being. Dietitians work with individuals to assess their nutritional needs, develop personalized meal plans, and provide education on healthy eating habits. They may work in a variety of settings, such as hospitals, schools, government agencies, and private practice, to help clients manage chronic diseases, optimize athletic performance, or achieve weight loss goals. Dietetics is a continuously evolving field, with a focus on evidence-based research and the promotion of sustainable and culturally appropriate dietary practices.
