Recipe Nutrition Calculator
Calculates calories and nutrition facts per serving for your recipes, using USDA food data.
Turns recipe ingredient lines into per-serving nutrition using USDA FoodData Central values. Converts cups, spoons and counted items to grams, scales recipes to a new serving count, and rounds results to FDA Nutrition Facts label rules with percent Daily Value. Ingredients it cannot match are listed, not guessed. No account or API key needed.
Try asking Muse: "Work out the calories and nutrition facts per serving for my lasagna recipe, which makes 8 servings."
