Taste of the Wild Canyon River Feline Recipe

9 ingredients in this list are ones we hold sourced evidence on , and 2 of them are genuinely contested rather than merely unpopular online.

• Lentils · ingredient 5ContestedA pulse (legume) common in grain-free formulas as a protein and carbohydrate source. Lentils are named alongside peas in the FDA's open 2018 investigation into diet-associated canine DCM; the agency grouped 'peas and/or lentils,' which appeared in 93% of reported products.
• Peas · ingredient 6ContestedA pulse (legume) used in many grain-free foods as a plant protein and carbohydrate source. Peas are central to an open FDA investigation, begun in July 2018, into a possible link between diets high in peas, other pulses, and potatoes and canine dilated cardiomyopathy (DCM); 93% of reported products contained peas and/or lentils.
• 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 7Well 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.
• Sweet potato · ingredient 4NeutralA starchy root used as a carbohydrate source and a source of fiber and beta-carotene in grain-free foods (a vegetable, not a cereal grain). The FDA's 2018 DCM investigation grouped 'potatoes (including sweet potatoes)' within its ingredients of interest, but the reported cases were dominated by pulses and white potato, and evidence isolating sweet potato specifically is limited.
• Taurine (supplemental) · ingredient 14NeutralA sulfur amino acid that dogs can normally synthesize from methionine and cysteine, so it is not classically essential for them. However, some breeds (e.g., golden retrievers) and some diets are linked to low taurine status and dilated cardiomyopathy: an observational study (Ontiveros 2020) associated non-traditional, largely grain-free diets with taurine deficiency and DCM-consistent echocardiographic changes in golden retrievers, though causation and mechanism remain under investigation.
