Diet-driven modulation of the gut microbiome supports improved pet health and longevity. However, the science is often confusing to pet owners and many animal health pros alike. In the white paper linked below, Jess Jarett, PhD, R&D principal pet scientist at Cargill, explains how specific macronutrient compositions of diets, as well as moisture content, help shape microbial communities.
Jarett reminds us that the gut is not an isolated digestive system but a command center communicating directly with the skin, joints and oral cavity via circulating metabolites and inflammatory signals.

Formulators and nutritionists can help bridge the gap in pet owner understanding, because many owners draw from human health trends yet have only a vague grasp of how diet influences the pet microbiome. Clear communication from pet industry professionals is essential to correct misconceptions, including the belief that biotic ingredients can solve every health issue.
Microbial communities within the gut are not only digestive aids but signaling systems that modulate organ systems including skin, joints and oral health.”
