Document Summary
Section 1. 3: what are the classes and sources of nutrients? concepts: what are the six classes of nutrients, what are the three general functions of nutrients in the body, what are phytochemicals, six classes of nutrients. Regulate body processes: table 1-1: functions of nutrients. Nutrient classes that provide energy: most carbohydrates, proteins, most lipids.
