Proteins Tier List

Protein is the only category scored on amino-acid quality (DIAAS) — because 20 grams of complete protein and 20 grams of incomplete protein are not the same thing. Liver sits at the top. Nobody is surprised.

How the grading works: scored per 100 calories on fixed benchmarks, weighted, ranked. Read the full methodology — the formula is published, argue with it.

A note before you eat your screen: grades are computed from published nutrition data with a transparent formula. They are a starting point for thinking about food, not medical advice. Talk to your doctor or a registered dietitian about your diet.
