This chapter discusses the Geometric Framework (GF) for nutrition. GF satisfies the multiple-food-components requirement using a simple device known as a nutrient space. A nutrient space is a geometric space built of two or more axes, where each axis represents a food component that is suspected to play a role in influencing the animal's responses to its environment. In most cases, these food components will be nutrients but this is not invariably the case. The nutrient space provides the common context in which to describe the pertinent aspects of the animal, its environment, the interactions between animal and environment, and the consequences of these interactions.

Keywords:   Geometric Framework, nutrition, multiple-food-components, food requirements, nutrient space, food components, animal nutrition
