Nutrition

Nutrition is the sum of all the interactions between an organism and the food it consumes. In other words, nutrition is what a person eats and how the body uses it. Nutrients are organic and inorganic substances found in foods that are required for body functioning. Adequate food intake consists of a balance of nutrients: water, carbohydrates, proteins, fats, vitamins and minerals. Foods differ greatly in their nutritive value (the nutrient content of a specified amount of food) and no one food provides all essential nutrients. Nutrients have three major functions: providing energy for body processed and movement, providing structural material for body tissues and regulating body processes.
