How the math works
- 1
Every food's protein content comes from USDA FoodData Central (source + access date embedded in data).
- 2
Cost per gram of protein = your price รท total protein grams per package.
Example: $3.99 for a dozen eggs รท 72g protein = $0.055/g
- 3
Unit conversions use 1 lb = 453.6g, 1 kg = 1000g. Switch the toggle anytime โ all prices and rankings recalculate.
Defaults are USDA retail price report averages, labeled as estimates. They're a starting point, not gospel โ your store is what matters.
