Essential Terms

• Nutrition: The study of how the body uses the food that is eaten. It is both a science and an art.
• Nutrient: A chemical substance in food that helps maintain the body. Nutrients support growth, support, and maintenance of normal body function. Some provide energy, and all help build cells and regulate bodily processes such as breathing. No single food supplies all the nutrients the body needs. (Human body needs approximately 50 different nutrients daily).
