Animal models are used extensively in nutritional research. Studies with animal models may not provide a discussion of the applicability of the model to humans, and seldom do such studies discuss the limitations of the model. This article presents information that is targeted toward the nutrition support practitioner about the use of animal models in nutritional research. The rationale for using animal models and the applicability to humans, the limitations of applicability, and the unique opportunities related to animal models is presented.
