Data sources

Scientific literature

When an article relies on scientific studies or on guidance from official bodies, its sources are listed at the end.

Food data

Generic foods come from the USDA FoodData Central database (public domain). Branded products come from Open Food Facts (ODbL licence). Every food shows its source. Labels do contain the odd mistake, which is why every page has a “Report an error” button.

Before a food is published, a person checks it: our team sets the Greek name, the category and the keto label. We carry the nutrition values over as the source gives them, per 100 grams. Net carbs are worked out as the “Methodology” page describes.

Business and product information

A business supplies its own details and those of its products (description, ingredients, nutrition from the label, links). Our team checks them before they are published. Net carbs and the keto label we calculate ourselves, with the same rules for everyone. Sponsored pages and affiliate links are marked.
