USDA nutrition numbers, real grocery prices, and one very long spreadsheet, so you can see exactly what your dollar buys.
53 foods ranked by how much fiber a dollar buys. Spoiler: the winners live in the dry goods aisle.
49 protein sources compared by cost per gram. The fancy stuff near the deli counter does not do well.
Punch in any food and its price. Find out if you're buying fiber or just paying for the packaging.
