What this feature does

Feast can surface richer fat information than a total-fat number when the supporting analysis contains it.

Why it can be useful

Fat type can matter to nutrition questions, but fatty-acid detail is only useful when the ingredient mapping and source record support it.

A careful workflow

Use the feature as a reviewable part of your record.

  • Check total fat alongside saturated and unsaturated fat fields that are available.
  • Look across repeated food choices rather than labeling one meal good or bad.
  • Inspect the analysis assumptions when fatty-acid subtotals do not reconcile cleanly.

Limits to keep visible

Convenience and analytical detail do not remove uncertainty.

  • Not every source food has complete fatty-acid data.
  • The feature is educational and does not prescribe treatment for cardiovascular or metabolic conditions.

Limits and cautions

  • Not every source food has complete fatty-acid data.
