Nutrition is the science that interprets the interaction of nutrients and other substances in food in relation to maintenance, growth, reproduction, health, and disease of an organism. It includes food intake, absorption, assimilation, biosynthesis, catabolism, and excretion. The diet of an organism can significantly impact its physical and mental health, influencing various aspects of well-being from immune response and physical development to cognitive function and chronic disease prevention. Essential nutrients required by the human body include carbohydrates, proteins, fats, vitamins, and minerals. These compounds provide energy, support growth and repair of tissues, and help regulate body processes. Public health recommendations promote balanced diets rich in fruits, vegetables, whole grains, and lean proteins, while minimizing processed foods high in sugar, salt, and unhealthy fats. Nutrition science also examines how environmental and social factors, such as access to food and eating habits, affect dietary intake and overall health.
