What this feature does

Feast's rich nutrient breakdown includes macronutrient and micronutrient context so users can look beyond a calorie total.

Why it can be useful

Macro totals answer different questions from vitamins, minerals, fatty acids, fiber, caffeine, or alcohol. A useful review starts with the user's actual goal and the reliability of the estimate.

A careful workflow

Use the feature as a reviewable part of your record.

  • Choose a small number of nutrients relevant to the question.
  • Review averages or recurring meals before reacting to a single estimate.
  • Check source and portion assumptions when a value looks surprising.

Limits to keep visible

Convenience and analytical detail do not remove uncertainty.

  • Estimated micronutrients can be missing or mismatched when database records are incomplete.
  • Nutrient tracking does not diagnose a deficiency or determine an individualized treatment target.

Limits and cautions

  • Estimated micronutrients can be missing or mismatched when database records are incomplete.
  • Nutrient tracking does not diagnose a deficiency or determine an individualized treatment target.
