Description
Explicit edible-portion food diary accounting, without nutrient recommendations or dietary adequacy assessment.
Pediatric research records use chronological age, visit windows, measurement resolution, task observations, and caregiver reports. Missing observation differs from noncompletion, and a completeness share depends on its denominator. Arithmetic on supplied records is separate from a developmental or clinical assessment.
Explicit edible-portion food diary accounting, without nutrient recommendations or dietary adequacy assessment.
When to use this tool
Use Child Meal Record Edible Leftover when you need this age, observation, visit, measurement, or record-completeness calculation with supplied inputs.
How to use the tool and how it works
- Enter servedMass, boneInedibleMass, edibleLeftoverMass, nutrientPerEdibleMass. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read edibleServed, consumedEdibleMass, consumedNutrient. Use the output convention below.
For nonnegative masses require boneInedibleMass+edibleLeftoverMass<=servedMass and nonnegative nutrientPerEdibleMass. Return edibleServed=served-bone, consumedEdibleMass=served-bone-leftover, and consumedNutrient=consumedEdibleMass*nutrientPerEdibleMass.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| servedMass | Served Mass | Required. Finite number; minimum 0. |
| boneInedibleMass | Bone Inedible Mass | Required. Finite number; minimum 0. |
| edibleLeftoverMass | Edible Leftover Mass | Required. Finite number; minimum 0. |
| nutrientPerEdibleMass | Nutrient amount per mass unit matching consumed edible mass. | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| edibleServed | Edible Served | Required. Finite number. |
| consumedEdibleMass | Consumed Edible Mass | Required. Finite number. |
| consumedNutrient | Consumed Nutrient | Required. Finite number. |

}Limitations and assumptions
- Masses need one unit and nutrient density must use the same edible-mass denominator. This is supplied meal accounting, not proof of ingestion, an adequate dietary assessment, or a feeding recommendation.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Signed zero is exported as zero.
Alternative or Complementary methods
Use verified dates, measurement protocols, and observation definitions for the intended research question. A clinical interpretation needs the relevant age-specific assessment and context beyond the arithmetic record check.
