Updated 24 September 2026
The recipes in the app's shared catalogue come from public bodies and open projects that let anyone reuse their work. Each recipe in the app keeps its publisher's credit. This page lists them all, with the licence each is used under.
Every catalogue recipe is adapted. Diet Handbook reads each ingredient line into an amount and a food, and works out the allergen, diet and nutrition figures itself. Those figures are ours, not the publisher's, and no publisher here has reviewed or endorses the app.
The app screens on the home page show some of these recipes as the app draws them, with their photographs cropped. Those photographs are from the University of Alberta cookbook, Health and Wellbeing Queensland and the NSW Government, credited below.
