USDA FoodData Central
JFS can use USDA FoodData Central for product and nutrition information. Coverage differs by product, and records may not always match the latest package label.
Source transparency
Know where the product data came from.
JFS uses named external data sources instead of presenting product information as if it were created in isolation. Coverage and freshness can vary by product and region.
Open Food Facts
JFS can use community-maintained Open Food Facts for product, ingredient, and nutrition information. Community data can be incomplete, outdated, or contain errors, so the current package remains the best source when records differ.
AI photo analysis
When a user explicitly chooses Analyze photo, the selected image is sent through the JFS service to OpenAI for constrained product-candidate and visible-label reading. The resulting match is then evaluated using available product records.
Why records can differ
Recipes change, package sizes vary, regional products differ, and third-party databases are updated on different schedules. JFS should show source information and handle incomplete or no-match states rather than implying universal coverage.
