Nutrition science is the study of how food affects the body and overall health. It explores the nutrients found in different foods, such as carbohydrates, proteins, fats, vitamins, and minerals, and how these components contribute to growth, energy, and disease prevention. Researchers in this field analyze dietary patterns and their impact on health outcomes. This discipline also examines the role of dietary guidelines and food policies in promoting healthy eating habits. By understanding the relationship between nutrition and health, scientists aim to develop strategies to improve public health and reduce the risk of chronic diseases like obesity, diabetes, and heart disease.
