6 ingredients in this list are ones we hold sourced evidence on , and 3 of them are genuinely contested rather than merely unpopular online.

• Potato · ingredient 5ContestedA 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.
• 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.
• Carrageenan · ingredient 7Worth 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.
• Cassia Gum · ingredient 8NeutralA gelling agent made from the purified endosperm of Cassia seeds, used mainly in canned and wet foods. It is specifically authorized in the EU as a pet-food thickener: EFSA (2017) concluded that purified semi-refined cassia gum meeting the food-additive specification (under 0.5 mg anthraquinones/kg) is safe for dogs and cats up to the permitted feed level.
• Guar Gum · ingredient 9NeutralA soluble, viscous fiber from the guar bean used in small amounts to thicken and stabilize foods, mostly wet formulas. At higher dietary inclusion it can lower the digestibility of dry matter and protein in dogs, but it also produces metabolic effects such as reduced post-meal insulin and cholesterol; at the low levels used as a thickener these effects are minor.
• Flaxseed (ALA omega-3) · ingredient 11NeutralA 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.
