First study on human-grade dog food says whole, fresh food is highly digestible

(University of Illinois College of Agricultural, Consumer and Environmental Sciences) some pet food companies are developing diets that more closely resemble human food, incorporating human-grade meat and vegetable ingredients that pass USDA quality inspections. Until now, little research had been done on these foods. A new study from the University of Illinois shows these diets are not only highly palatable, they are more digestible than originally estimated.
