Tapioca Starch
Refined starch extracted from cassava root, used in extruded kibble to bind particles and help the kibble expand. Common in grain-free formulas as a replacement for cereal grains. It cooks to a high degree during extrusion — grain-free diets averaged about 94% starch gelatinization versus 88% for grain-based — which means it is digested rapidly and contributes little resistant starch.
What it's doing there
Binder / carbohydrate source.
The concern
Highly digestible with negligible resistant starch, so it offers no prebiotic benefit and is rapidly absorbed. Its presence high in an ingredient list signals a formula leaning on refined carbohydrate for structure rather than nutrition.
How sure are we
Moderate. There is reasonable information available, but less of it, or less agreement than we would like.
Note: Resistant starch in commercial extruded pet foods measured below 1% of total starch — too low to support colonic health.

This application is intended for educational purposes only. Scores are generated using publicly available product information and are not veterinary advice. We are not veterinarians. Always consult your veterinarian regarding medical decisions.
A high score does not mean a product is right for your pet, and a low score does not mean it is dangerous. An individual animal can react to an ingredient that scores well here, and a product with a mediocre score may be exactly what your vet recommends.
The score reads ingredients one at a time. It cannot account for how ingredients interact with each other, with other products you use, or with your pet's medications and conditions. Two ingredients that are each fine on their own may not be fine together. A score is a starting point for questions, not a substitute for professional judgment.
