description: A record of intake by a patient.  A NutritionIntake may indicate that the patient may be consuming the food (i.e., solid and/or liquid), breastmilk, infant formula, supplements, enteral formula now or has consumed it in the past.  The source of this information can be the patient, significant other (such as a family member or spouse), or a clinician.  A common scenario where this information is captured is during the history taking process during a patient visit or stay or through an app that tracks food (i.e., solid and/or liquid), breastmilk, infant formula, supplements, enteral formula consumed.   The consumption information may come from sources such as the patient's memory, from a nutrition label, or from a clinician documenting observed intake.
