Polyunsaturated Fat

Dietary Fat Polyunsaturated records a total logged polyunsaturated-fat amount in g. Apple defines it as a cumulative mass quantity. It does not specify an omega-3 dose or an omega-6 amount.

NIH describes omega-3 and omega-6 as major PUFA classes, with distinct omega-3 forms including ALA, EPA and DHA. One combined HealthKit quantity cannot separate these components or establish an omega-6-to-omega-3 ratio.

PUFA is a component of total fat in Apple's nutrition hierarchy. Adding both double counts the same contribution. Incomplete subtype composition is common enough that an absent record must stay missing; it cannot establish zero PUFA in food.

The log describes recorded intake, with food-database and portion uncertainty. It cannot establish absorption, tissue fatty-acid levels or a supplement's effect. There is no general normal range for each food sample. Review supplement composition separately, and avoid applying an omega-3-specific dose recommendation to total PUFA grams.

This HealthKit concept is documented in the knowledge base, but it is absent from the current PulsHealth collection catalog. Automatic sync is not provided for this type by that catalog. Its absence from the database does not establish that Apple Health contains no records.

Entry timing follows food logging or source synchronization. A timestamp may describe an earlier meal or a daily summary. Review start times, durations and source history before discussing meal timing. Missing days remain unlogged rather than zero intake. Health's source controls help when reviewing overlapping apps.

The researched 365-day reporting window contained no raw samples or stored aggregates for this nutrient. Recorded ranges, unusual portions, source overlap, recording intervals were unavailable. Related nutrient comparisons were unavailable because there were no records for this type. No empirical nutrient association or measured chart is supported. These missing records do not establish zero consumption or a deficient diet.

Check the represented serving, preserve source-specific daily totals and state how many days have usable logs. Review duplicate food imports before summing sources. Food descriptions may clarify portions when supplied, but absent metadata does not prove automatic measurement or complete recording.
