Plant Proteins Tier List
Protein quantity and quality (DIAAS where published), plus fiber for the legume crowd. The meat-alternative showdown, scored straight.

Mycoprotein (Quorn)
51Fungus you eat on purpose. Weirdly complete, weirdly inoffensive.

TVP (Textured Vegetable Protein)
50Defatted soy flour doing a ground-beef impression. 52g protein per 100g dry.

Tofu (Firm, Calcium-Set)
49The calcium-set kind is basically a calcium supplement that happens to contain protein.

Seitan
47Wheat gluten cosplaying as meat — protein quantity without the quality.

Nutritional Yeast
44Deactivated yeast with a main-character complex. Cheesy without the cheese.

Mung Beans
43Dal's quiet overachiever. Folate for days.

Lupini Beans
42The Mediterranean bar snack with a bodybuilder's protein count.

Split Peas
41Soup's hardest worker. 8g fiber doing the quiet heavy lifting.

Lima Beans
40The bean everyone skipped as a kid. The potassium numbers say they were wrong.

Natto
40Soybeans that went feral. Stringy, stinky, superb.

Adzuki Beans
39The dessert bean that moonlights as a protein source.
