Protein source
Ingredient guideWhole plant source plus processed protein support
Animal protein
Beef (#1), Lamb Meal (#2), Salmon Meal (#5), Beef Heart (#8), Beef Liver (#12), Beef Kidney (#15), Beef Tripe (#16)
Plant protein
Chickpeas (#3), Peas (#4), Lentils (#6), Pea Protein (#7)
The top-3 whole plant source is a possibility signal, while the later processed plant protein is a clear protein-support signal.
Because both possible and clear plant-protein signals appear, the protein number is read conservatively.
