Nutrition

If enough data is available norish shows the protein, fats, carbs and calories of a recipe. When the source does not state it the macros are worked out from the ingredients. This works on every server, with or without AI.

How it works

Each line of the recipe is turned into grams and counted through the numbers per 100 g of its ingredient:

  • A weight (“200 g onion”, “1 lb rice”) is used as is.
  • A count (“2 onions”, “2 large eggs”, “3 cloves garlic”, “1 slice bread”) uses the average a piece weighs
  • A volume (“1 tsp cumin”, “2 tbsp olive oil”, “1 cup milk”, “100 ml stock”) uses its spoon weighs settable in the ingredient panel
  • When the weight is stated in brackets that is used: “1 (15 ounce) can coconut milk”, “1 can (400 g) tomatoes”, “1 tsp (3 g) paprika”.
  • A pinch, a dash or “to taste” is seasoning and never counted.

The nutrition card always shows what is counted and what isn't with the reasoning.

A teaspoon is 5 ml, a tablespoon 15 ml and a cup 240 ml.

The total is divided by the recipe's servings to get a per portion estimate.

The data

Each ingredient has its numbers per 100 g, what one piece weighs and what a spoon of it weighs. Open Settings => Ingredients and click an ingredient to see the data.

The order

  1. Your (household's) correction.
  2. A food Norish chose for it, where the dataset's usual pick is wrong for cooking: “milk” is whole milk, not skimmed, and “corn” is sweet corn, not dry grain. Marked with: chosen by Norish.
  3. The food the ingredient's Open Food Facts code names in CIQUAL, CALNUT or USDA FoodData Central.
  4. A dataset food with the same name. Marked with: matched by name.
  5. The nearest more general food that has numbers: “red onion” borrows from “onion”. Marked with: from onion, so filing a food under a parent gives it nutritional values as well. A few general foods never lend their numbers, because their children differ too much such as: sauces, pure alcohol and fruit.

The datasets

The datasets are CIQUAL 2025 and CALNUT (ANSES), USDA FoodData Central and CoFID.

Correcting nutrition

If Norish's numbers don't match what you buy, open Nutrition in the ingredient's panel and press Correct. Anyone in your household can correct any ingredient, and corrections are scoped to your household: nobody else sees them. Each fact says what Norish has for it now. For each of the numbers per 100 g, the weight of one piece and the weight of a spoon (in the measure your recipes use for it), choose:

  • No correction: keep Norish's numbers,
  • A dataset food: search the datasets by name, such as “milk semi-skimmed”,
  • From a label: type the numbers from a pack.
