Small enough to work offline

The application catalog contains 71 foods, 168 nutrient definitions, 61 food-specific volume anchors and 56 matching-capable foods. The catalog is about 166 kB before compression (about 30 kB with gzip). Larger provenance and tabular exports are separate files.

What is included

Browse the complete food reference atlas or explore four illustrated combinations.

The catalog focuses on whole foods and simple culinary ingredients, with separate preparation records. It includes plant foods, eggs, meat, fish, plain dairy, tofu and tempeh. It includes basic cooking ingredients such as salt, honey, cocoa, natural peanut butter and olive oil. There are no brand rankings or protein-isolate products.

Four foods have incomplete amino-acid panels: Tempeh, cooked; Plain Greek whole-milk yogurt; Amaranth, cooked; Lemon juice, raw. They retain their other nutrients. No catalog food has an approved digestibility coefficient join. Unknown values are never filled with invented zeros.
