This program examines the chemical structure of food and the human body’s ability to convert food into fuel and raw materials. Major and minor nutrients are defined, catabolism and anabolism are contrasted, and the function of the digestive tract at the cellular level is scrutinized.

A segment on healthier eating concludes the program. A viewable/printable instructor’s guide is available online. A Films for the Humanities & Sciences Production.
