The full Protein per Dollar Index: 49 protein sources ranked by protein grams per dollar, with package prices, edible fractions and price per 100g. Primary nutrition source: USDA FoodData Central. TVP is a proxy: USDA publishes no textured vegetable protein record at all, so the row is sourced to the manufacturer label at 52.17 grams per 100 grams. Current row-level source audit: 39 exact USDA matches and 10 close proxies, with no unresolved rows; proxy rows are not independently re-verified.
