USDA FoodData Central publishes no textured vegetable protein entry, so this row is sourced to the manufacturer label of the exact priced product. The Bob's Red Mill product page was fetched 2026-08-02 and states serving size 1/4 cup (23g) with 12g protein, which is 52.17 g per 100 g. The previous 50.0 g per 100 g figure matched neither that label nor any USDA record and was unsupported; it has been corrected to 52.17 and protein_g_per_dollar recomputed from 22.5 to 23.4, which moves this row above canned kidney beans. The label rounds protein to the nearest gram, so the underlying value lies roughly between 50.0 and 54.3 g per 100 g. USDA's nearest analogue, Soy flour, defatted (FDC 174275) at 51.5 g per 100 g, corroborates the magnitude but is untextured flour and is not cited as this row's source."}},{"dataset":"protein-per-dollar-2026","food":"Canned kidney beans","category":"Canned beans","nutrients":["protein"],"metrics":{"protein_g_per_dollar":23.4},"package":"15.5 oz can","price_usd":0.98,"price_basis":"Walmart GV (fiber study, audited)","rank":32,"fields":{"rank":32,"food":"Canned kidney beans","category":"Canned beans","protein_g_per_100g":5.22,"package":"15.5 oz can","package_price_usd":0.98,"package_weight_g":439,"edible_fraction":1,"price_per_100g_usd":0.223,"protein_g_per_dollar":23.4,"price_basis":"Walmart GV (fiber study, audited)","nutrition_source_status":"exact","nutrition_source_type":"USDA FoodData Central SR Legacy","nutrition_source_id":"FDC 173741","nutrition_source_url":"https://api.nal.usda.gov/fdc/v1/food/173741?api_key=DEMO_KEY","nutrition_source_description":"Beans, kidney, all types, mature seeds, canned","nutrition_source_form":"All types, mature seeds, canned","nutrition_source_note":null}},{"dataset":"protein-per-dollar-2026","food":"Canned tuna (chunk light, in water)","category":"Fish (canned & frozen)","nutrients":["protein"],"metrics":{"protein_g_per_dollar":22.4},"package":"5 oz can (113 g drained)","price_usd":0.98,"price_basis":"Walmart GV Jul 2026","rank":33,"fields":{"rank":33,"food":"Canned tuna (chunk light, in water)","category":"Fish (canned & frozen)","protein_g_per_100g":19.44,"package":"5 oz can (113 g drained)","package_price_usd":0.98,"package_weight_g":113,"edible_fraction":1,"price_per_100g_usd":0.867,"protein_g_per_dollar":22.4,"price_basis":"Walmart GV Jul 2026","nutrition_source_status":"exact","nutrition_source_type":"USDA FoodData Central SR Legacy","nutrition_source_id":"FDC 173709","nutrition_source_url":"https://api.nal.usda.gov/fdc/v1/food/173709?api_key=DEMO_KEY","nutrition_source_description":"Fish, tuna, light, canned in water, drained solids (Includes foods for USDA's Food Distribution Program)","nutrition_source_form":"Canned in water, drained solids","nutrition_source_note":null}},{"dataset":"protein-per-dollar-2026","food":"Pork loin chops (boneless)","category":"Meat & poultry","nutrients":["protein"],"metrics":{"protein_g_per_dollar":22.3},"package":"per lb","price_usd":4.39,"price_basis":"BLS US avg May 2026 (APU0000FD3101)","rank":34,"fields":{"rank":34,"food":"Pork loin chops (boneless)","category":"Meat & poultry","protein_g_per_100g":21.55,"package":"per lb","package_price_usd":4.39,"package_weight_g":454,"edible_fraction":1,"price_per_100g_usd":0.967,"protein_g_per_dollar":22.3,"price_basis":"BLS US avg May 2026 (APU0000FD3101)","nutrition_source_status":"exact","nutrition_source_type":"USDA FoodData Central SR Legacy","nutrition_source_id":"FDC 167839","nutrition_source_url":"https://api.nal.usda.gov/fdc/v1/food/167839?api_key=DEMO_KEY","nutrition_source_description":"Pork, fresh, loin, top loin (chops), boneless, separable lean and fat, raw","nutrition_source_form":"Top-loin chop, boneless, lean and fat, raw","nutrition_source_note":null}},{"dataset":"protein-per-dollar-2026","food":"Canned chickpeas","category":"Canned beans","nutrients":["protein"],"metrics":{"protein_g_per_dollar":22},"package":"15.5 oz can","price_usd":0.98,"price_basis":"Walmart GV (fiber study, audited)","rank":35,"fields":{"rank":35,"food":"Canned chickpeas","category":"Canned beans","protein_g_per_100g":4.92,"package":"15.5 oz can","package_price_usd":0.98,"package_weight_g":439,"edible_fraction":1,"price_per_100g_usd":0.223,"protein_g_per_dollar":22,"price_basis":"Walmart GV (fiber study, audited)","nutrition_source_status":"proxy","nutrition_source_type":"USDA FoodData Central SR Legacy","nutrition_source_id":"FDC 175206","nutrition_source_url":"https://api.nal.usda.gov/fdc/v1/food/175206?api_key=DEMO_KEY","nutrition_source_description":"Chickpeas (garbanzo beans, bengal gram), mature seeds, canned, solids and liquids","nutrition_source_form":"Mature seeds, canned, solids and liquids","nutrition_source_note":"The regular-sodium record is cited because the priced can is not labelled low sodium, but the price record does not state the sodium variant; the low-sodium record FDC 175250 reports the identical 4.92 g protein per 100 g, so the ambiguity does not affect this row's protein value (the records differ only in sodium, 278 vs 132 mg per 100 g).
