/// A record of food or fluid that is being consumed by a patient. A
/// NutritionIntake may indicate that the patient may be consuming the food or
/// fluid now or has consumed the food or fluid in the past. The source of this
/// information can be the patient, a 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 at an encounter or visit.
///
/// In FHIR R5 this resource supports nutrition and dietary workflows by
/// documenting what was actually taken in, distinct from what was ordered or
/// dispensed. It captures oral intake, enteral feeding, and fluid consumption,
/// including cases where an item was offered but refused or not consumed. Each
/// entry can record the specific food or fluid product, its scheduled timing,
/// the amount and administration rate, and an optional nutrient label breakdown,
/// which makes the resource useful both for clinical review during history
/// taking and for downstream dietary and nutritional analysis. A NutritionIntake
/// is always anchored to a subject and may be linked to the encounter during
/// which it was recorded, the performer who administered or observed the intake,
/// and the location where it occurred.
///
/// # Related resources
///
/// The [`subject`](NutritionIntake::subject) is commonly a
/// [`Patient`](crate::r5::resources::patient::Patient), and the
/// [`encounter`](NutritionIntake::encounter) references the
/// [`Encounter`](crate::r5::resources::encounter::Encounter) in which the intake
/// was captured. Coded and referenced values throughout use
/// [`CodeableConcept`](crate::r5::types::CodeableConcept),
/// [`CodeableReference`](crate::r5::types::CodeableReference), and
/// [`Reference`](crate::r5::types::Reference). This resource is closely related
/// to `NutritionOrder`, which represents the request or prescription, and to
/// `NutritionProduct`, which describes the food or fluid product itself.
///
