Evidence labels

Pages distinguish government datasets, official guidelines, systematic reviews, individual studies, first-party product documentation, and editorial inference. These evidence types are not interchangeable. A source list should make it possible to tell whether a sentence describes reference composition, a research finding, current product behavior, or Feast's interpretation.

Source selection and citation placement

Sources should be primary or authoritative when feasible and should directly support the nearby claim. Nutrition reference pages preserve a stable public record identifier. Product claims point to current first-party documentation or direct verification and are labeled accordingly. A reputable link is not added merely to lend authority to a broader, unsupported sentence.

Claims we avoid

Feast does not publish unsupported claims of exact photo accuracy, proven superiority, guaranteed behavior or health outcomes, causation from observational sleep patterns, diagnosis, or medical treatment. Product capability is not efficacy evidence. Statistical association is not causation. A citation to a nutrient database does not validate the inferred identity or portion of a photographed meal.

Programmatic content controls

Generated nutrition pages must preserve unique source identifiers, reproducible serving math, explicit range meaning, and useful internal relationships. Build validation rejects duplicate identifiers, malformed records, broken paths, implausible portions, and missing required provenance. Automation handles structure at scale; editorial review remains responsible for naming, interpretation, and whether a page answers a real reader question.

Publication and review status

Published product and resource pages require a completed internal review status and a named editorial role. Research explainers that need qualified methodology review remain draft and noindex until that review is complete. Dates indicate when the current version was published, updated, checked, or scheduled for review; they do not guarantee that an external source has not changed sooner.

Corrections

Readers can report an error through Feast's published support channel. A material correction updates the affected source, claim, calculation, or interpretation and refreshes the editorial date. When an issue comes from a shared template or data transformation, the generator is fixed so every affected page is rebuilt consistently rather than patching only the reported URL.

Limits and cautions

  • This resource is educational and does not provide individualized medical or nutrition treatment.
  • Methods and product behavior are reviewed periodically; the displayed review date indicates the current editorial version.
