Good Neutral Watch Flagged
  1. 1
    chicken meal

    Chicken with the water cooked out. Per pound, packs more protein than fresh chicken.

  2. 2
    tapioca starch

    Refined cassava starch, used as a binder. Easy to digest, low on nutrition.

  3. 3
    potato

    Standard white potato. Steady carb source, common starch in grain-free recipes.

  4. 4
    peas

    Cheap protein bulk. Fine in small amounts, but when peas stack with lentils and chickpeas in the top ingredients, it's the pattern the FDA flagged in its heart-disease investigation. See why →

  5. 5
    powdered cellulose

    Plant fiber, often from wood pulp. Cheap bulk filler. Not harmful, but a tell that the recipe is reaching for inexpensive bulk.

  6. 6
    salmon meal

    Salmon cooked into a dry concentrate. Carries both protein and natural omega-3s in one ingredient.

  7. 7
    chicken fat

  8. 8
    ground whole flaxseed

    egg product

    Processed whole eggs. Same nutritional profile as fresh eggs, just shelf-stable.

  10. 10
    dried porcine plasma
  11. 11
