THERAPEUTIC NUTRITION FOR DISEASE-SPECIFIC

MANAGEMENT IN COMPANION ANIMALS

In the modern era, the role of pet nutrition is no longer limited to merely providing the energy required for
survival. It has evolved into “therapeutic nutrition,” playing a vital role in disease management and promoting
longevity in companion animals. Understanding the physiological mechanisms of diet is paramount for product
developers, facilitating the transition from mere “food manufacturers” to “health creators.” The primary
mechanisms for modulating health outcomes through nutrition can be categorized into two principal pathways:
the modulation of key nutritional factors and the delivery of active substances into the body.

Management through the modulation of key nutritional factors previously regarded as an immune-supporting supplement, recent
