  "description": "Every public dataset behind the Daily Life Hacks grocery cost studies: fiber per dollar, protein per dollar, protein quality adjusted with DIAAS, daily menu costing, and category-level rankings across produce, grains, legumes, dairy, meat, pantry staples and fast food.\n\nGrocery nutrient values primarily trace to USDA FoodData Central; the flagship files expose exact, proxy, and unresolved row-level status, and documented product-label exceptions remain labeled as such. Restaurant values come from chain-published nutrition. Prices are US national figures: BLS Average Price data where the item is tracked, Walmart national listings otherwise, observed July 2026. Every ranking is calculated as-purchased, with USDA refuse percentages removed so peels, pits and bone are not counted as food.\n\nThe original Daily Life Hacks selection, arrangement, calculations, field descriptions, and explanatory material are licensed CC BY 4.0.
