Studies on food selection in non-human primates were reviewed from the viewpoint of optimal food selection. Key factors in the classical model of optimal food selection were "maximization" of the "intake rate" of "energy". Later, the key factors were changed to "maximization" of the "contents" of "energy-essential nutrients" and "minimization" of the "contents" of "digestion inhibitor-toxins" in a modified model for herbivores. Most studies on food selection in herbivorous non-human primates have been based on the modified model, and revealed that primates choose food so as to maximize protein, and to minimize digestion inhibitiors (fiber, condensed tannin). However, the present review points out that the above key factors of the classical model are also important because food availability relating these factors correlates positively with feeding frequency.
