Dietary science is the study of how food and nutrition affect human health. It explores the relationship between diet, lifestyle, and various health outcomes, including the prevention of diseases. Researchers in this field analyze the composition of foods, dietary patterns, and the impact of nutrients on the body. This discipline also examines the role of vitamins, minerals, and macronutrients in maintaining overall well-being. By understanding how different foods influence metabolism and health, dietary science aims to provide evidence-based guidelines for healthy eating and promote better dietary choices among individuals and communities.
