Purina Beyond Beyond Cage-Free Turkey, Sweet Potato & Spinach Recipe In Gravy Natural Cat Food

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

• Carrageenan · ingredient 16Worth knowingA seaweed-derived (Chondrus crispus) thickener and gelling agent used mainly in some wet and canned dog foods. Low-molecular-weight 'degraded' carrageenan (poligeenan) is inflammatory in lab-animal studies and is not permitted as a food additive, but food-grade undegraded carrageenan (E 407) is authorized by regulators; EFSA's 2018 re-evaluation kept only a temporary group ADI of 75 mg/kg body weight per day pending better data, and its specific effect in dogs is unresolved.
• Wheat Gluten · ingredient 4NeutralThe concentrated protein fraction of wheat, used as a plant protein and binder; it is highly digestible in dogs (about 88% crude-protein digestibility in one feeding study). The 2007 pet-food deaths linked to wheat gluten were caused by criminal melamine adulteration of imported product to fake protein readings, a contamination event rather than a property of wheat gluten itself.
• Sweet potato · ingredient 7NeutralA 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.
• Prebiotics (chicory root / inulin, FOS) · ingredient 11NeutralFermentable fibers (chicory-derived inulin and fructooligosaccharides) that feed colonic bacteria and are readily fermented to short-chain fatty acids in dogs. Feeding studies show they shift fecal microbiota composition and are well tolerated at typical inclusion levels, but clear health benefits beyond compositional change are not yet established.
• Xanthan Gum · ingredient 13NeutralA fermentation-derived polysaccharide used as a thickener and stabilizer, mainly in wet and gravy-style foods. EFSA's 2017 re-evaluation found no safety concern and concluded no numerical ADI was needed; direct studies in dogs are limited, but at the small amounts used it acts as a non-absorbed, largely fermentable fiber.
• Taurine (supplemental) · ingredient 15NeutralA 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.
