What is nutrition?
Nutrition is the science of food. It is the study of the nutrients and substances that make up food. Nutrition looks at the action, interaction, and balance of food as it relates to health and disease and the process of how the body digests, absorbs, transports, uses, and eliminates food.
Nutrients are substances needed for health that the body cannot make or makes in amounts too small to support health. Nutrients primarily provide energy, support growth and development, and keep body functions running smoothly.
