How the Database Is Built

Original Photography

Every photo in the app is original — personally photographed and weighed with real portions. No stock images are used. Rather than relying on AI to estimate portion sizes (where you can never be sure if the result is accurate) or weighing all your food on a kitchen scale, the app offers a practical middle ground: real photos of the most common portions with their actual weight. Tap the photo that looks like your portion and the grams are set automatically. If you had more than one of that serving, increase the number of portions. Or compare your food with the photos to estimate your portion size and enter the grams manually. Photos show food as it naturally appears, but the weight reflects only the edible portion, excluding peels, bones, seeds, and other inedible parts.

Regional Focus & Languages

The app is built for health-conscious adults in Spain, Italy, France, and Germany. The aim is to cover the most commonly eaten foods in these regions, with support for six languages: English, Spanish, Italian, French, German, and Portuguese. If you are outside these regions and find enough foods for your diet, that's great.

USDA Food Selection

All foods marked “USDA” are sourced from the USDA FoodData Central database. For each food, careful analysis was used to select which specific USDA entry best represents that food as commonly consumed in these regions, since the USDA database can contain multiple entries for the same food type with varying nutritional profiles. Most foods come from the SR Legacy data type, which was selected specifically because it provides the most complete micronutrient profiles, including vitamins, minerals, amino acids, and omega-3 and omega-6 fatty acids. A small number come from the Foundation and Survey (FNDDS) data types for foods not available in SR Legacy. Each entry's USDA source page is saved locally as a PDF. This serves both as an offline archive of the original source (so the citation stays intact even if USDA later changes or removes the page) and lets a Python script verify the entry's nutritional values against it. In a few cases, values were adjusted using a related USDA entry or a standard conversion.

AMFT Foods

Foods marked “AMFT” fall into two categories: composite foods made up of multiple ingredients, or packaged foods where nutritional data was obtained from the manufacturer. Composite foods show a complete ingredient breakdown with percentage composition, aiming to reflect how that food is commonly prepared in Spain, Italy, France, and Germany. Where ingredients vary by region, the most widely used or neutral option is chosen.
