 What happens to the food we eat, and how does it benefit the body? This video illustrates how the six essential nutrient classes—carbohydrates, proteins, amino acids, vitamins, minerals, and water—function. It also explains mechanical and chemical digestion, the expenditure of energy, and the process of metabolism, a collection of chemical reactions that convert the fuel in food into the energy needed to power everything we do. Viewable/printable educational resources are available online. Not available for preview. (23 minutes)
