Corn Meal
plant protein controversial
Ground corn used as a starchy binder/filler; 4th ingredient in Marshall Premium Ferret Diet.
Why it's debated: Cheap, high-starch filler that contributes to blood sugar instability and displaces animal protein. Widely criticized for an obligate carnivore; subject to ingredient-splitting. Its 4th-place position in Marshall Premium is a common criticism.
