Nutrients

Nutrient values in our database are expressed per 100 grams. This applies to all standard nutrient fields across our API responses.

Exception for evaluation

An exception is made for /evaluation responses, where values are expressed per total amount of food entries in the request. In simpler terms, the /evaluation endpoint provides nutrient totals for an entire protocol.

Big7 Units Reference

Below is an overview of the default units used for the Big 7 nutrients. For all other nutrients, the same fixed-unit principle applies as listed in the full Nutrient Units Reference in the section below.

Note

These units are consistent across all endpoints, ensuring comparability and predictable interpretation of values.
