Dietary Sodium

Dietary Sodium is a cumulative mass quantity for the sodium amount recorded as consumed. Amounts on this page are expressed in mg. One sample can represent a food portion, a supplement entry or a source-generated daily total; it is not necessarily a whole day. Apple defines this quantity.

Dietary Sodium stores the sodium amount entered from foods, drinks and other logged sources. Salt contains sodium and other components, so grams of salt are not grams of sodium. For pure table salt, sodium is about 40% of its mass; other ingredients and salt substitutes need their own composition. FDA explains sodium on food labels.

FDA uses a Daily Value of less than 2,300 mg for sodium. That is general label guidance, not a normal range for each HealthKit sample or an individualized treatment target. Compare complete daily logs, not a single food entry, and check the serving count. Restaurant recipes, sauces and salt added in cooking can make an apparently complete day incomplete.

The interval between entries reflects logging or synchronization, not nutrient absorption or a validated meal schedule. A midnight timestamp may be a daily summary, and multiple entries may have been added later. Review source, portion and duration before summing; importing the same meal from two apps can inflate a total. A day without entries is missing coverage, not zero intake.

Recorded sodium and blood pressure may be compared descriptively when both have adequate coverage, but an association does not isolate salt sensitivity or establish causation. Dietary entries do not measure sweat sodium or replacement needs. Weight and water records offer context rather than proof of sodium-related fluid changes. Dietary sodium also does not diagnose low or high blood sodium.

The researched 365-day reporting window contained no raw sodium samples and no stored sodium aggregates. Recorded value ranges, unusually large entries, source-specific daily totals and logging gaps could not be measured. No empirical graph or nutrient-status conclusion is presented. Related measurements cannot supply an intake relationship without sodium observations.

Check nutrient units and serving count: 1 g = 1,000 mg, while 1 microgram = 0.001 mg. Keep compatible contributions within a source and state how many days have credible logs. Apple allows apps to write selected nutrition types, so another nutrient being present does not establish complete sodium coverage. Review contributing Health sources after changing logging apps.

The current PulsHealth sync catalog includes Dietary Sodium in mg. Database absence still does not establish that the phone contains no sodium records or that logging was complete.
