12 ingredients in this list are ones we hold sourced evidence on , and 1 of them is genuinely contested rather than merely unpopular online.

• Potato · ingredient 6ContestedA starchy tuber used as the carbohydrate base in many grain-free foods (it is a vegetable, not a cereal grain). The FDA's open 2018 investigation into diet-associated canine DCM listed potatoes 'in various forms' as main ingredients of interest alongside pulses such as peas and lentils.
• Named Muscle Meat (e.g., Deboned Chicken, Beef, Salmon) · ingredient 1Well supportedA named fresh muscle meat identifies both the species and that it is clean flesh (AAFCO defines 'meat' as the clean flesh of a specified slaughtered mammal, and 'poultry' as clean flesh and skin). Naming the species is what lets an owner verify a protein for allergy avoidance.
• Named Meat/Poultry Meal (e.g., Chicken Meal, Lamb Meal) · ingredient 2Well supportedA rendered, water- and fat-reduced concentrate from a named species (AAFCO, e.g., 'chicken meal'). Because most moisture is removed it is a dense protein source (poultry meals commonly around 57-69% crude protein) and it names the species for allergy avoidance.
• Mixed tocopherols (natural vitamin E) · ingredient 12Well supportedA blend of vitamin E forms (alpha-, beta-, gamma-, delta-tocopherol) used as a natural-source antioxidant to slow fat rancidity, commonly chosen as an alternative to synthetic preservatives. EFSA concluded that tocopherol-rich extracts are safe for all animal species and the consumer and are efficacious antioxidants in feed.
• Rosemary extract · ingredient 70Well supportedA plant-derived natural antioxidant (active compounds carnosic acid and carnosol) used to slow fat oxidation, frequently chosen as an alternative to synthetic preservatives. It is an authorized food antioxidant in the EU (E 392); JECFA established a temporary acceptable daily intake for rosemary extract expressed as carnosic acid plus carnosol.
• Powdered Cellulose · ingredient 5NeutralPurified plant cell-wall fiber (typically from wood pulp) used as an insoluble-fiber source, bulking agent, and anti-caking aid, often in weight-management diets. It is not absorbed and is poorly fermentable, so it firms stool and dilutes calories but yields little of the short-chain fatty acids that more fermentable fibers produce; EFSA's 2018 re-evaluation found no safety concern and no need for a numerical ADI.
