Iams PROACTIVE HEALTH™ SENIOR WITH SLOW COOKED CHICKEN AND RICE CLASSIC GROUND

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 12Worth 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.
• Fish oil (EPA + DHA omega-3) · ingredient 18Well supportedMarine-source omega-3 fatty acids (EPA and DHA) from fish oil. A randomized, double-blinded controlled trial (Roush 2010) found improved weight-bearing in dogs with osteoarthritis, and a 2022 meta-analysis identified clear clinical analgesic efficacy for omega-3-enriched diets and supplements.
• By-Product Meal (Meat / Poultry By-Product Meal) · ingredient 2NeutralA rendered concentrate made from clean, non-muscle parts of the carcass (organs, necks, feet, and similar), defined by AAFCO. It is more variable and lower-transparency than a named muscle meal, but it is not inherently unsafe or low-nutrition: controlled feeding trials in dogs report high protein digestibility (roughly 92-95%) for poultry by-product-based diets, and some by-product organs are nutrient-dense.
• Wheat Gluten · ingredient 7NeutralThe 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.
• Flaxseed (ALA omega-3) · ingredient 8NeutralA plant source of the short-chain omega-3 ALA. Dogs convert ALA to the long-chain omega-3s inefficiently: a controlled feeding study (Dunbar 2010) found flaxseed raised serum EPA but produced no measurable DHA.
• Xanthan Gum · ingredient 14NeutralA 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.
