Nutrition data sources and updates
GLP Food Score compares listed nutrition values. Restaurant formulations, portions and menus change, so we maintain source, serving-basis and retrieval records separately from the score itself.
Source priority
Official restaurant nutrition pages and documents are authoritative for that restaurant’s current products. Government data is used for general foods. Traceable third-party records may preserve historical lineage while an official menu is being reconciled.
What we record
Where available, each nutrition record retains its source URL, serving basis, retrieval date, verification date and any transformation required to normalize units. Unknown nutrients remain unknown; they are not silently converted to zero.
Restaurant verification dates
Restaurant pages display the latest official-menu verification date and whether the complete active menu or only part of it has been checked. A build or deployment date is never presented as a nutrition verification date.
Update schedule
We review official restaurant nutrition sources on a recurring freshness schedule and sooner when a material menu change is identified. Updates are reconciled in staging, tested and released in controlled batches.
Corrections and limitations
Nutrition values can vary by location, preparation and selected modifiers. If a source or serving identity is genuinely ambiguous, nutrition-derived claims may be withheld internally until resolved. To report a correction, email hello@glpfoodscore.com.
