public final class Nutrient

Object
Nutrient

A single nutrient that a NutritionSample can carry – a macronutrient, a vitamin, a mineral.

Interned constants, like HealthDataType, so == is a valid identity test and forId(String) stays total across framework versions.

Each nutrient declares the unit its amounts are expressed in. That is not cosmetic: sodium is conventionally logged in milligrams and protein in grams, and a food database that mixes them up is off by a thousand.

Field details

ENERGY

public static final Nutrient ENERGY

Food energy. Note that this is also available as a standalone type, HealthDataType.DIETARY_ENERGY; writing a NutritionSample that carries it makes it part of a logged meal rather than a bare total.

PROTEIN

public static final Nutrient PROTEIN

TOTAL_FAT

public static final Nutrient TOTAL_FAT

SATURATED_FAT

public static final Nutrient SATURATED_FAT

MONOUNSATURATED_FAT

public static final Nutrient MONOUNSATURATED_FAT

POLYUNSATURATED_FAT

public static final Nutrient POLYUNSATURATED_FAT

TRANS_FAT

public static final Nutrient TRANS_FAT

CHOLESTEROL

public static final Nutrient CHOLESTEROL

TOTAL_CARBOHYDRATE

public static final Nutrient TOTAL_CARBOHYDRATE

DIETARY_FIBER

public static final Nutrient DIETARY_FIBER

SUGAR

public static final Nutrient SUGAR

WATER

public static final Nutrient WATER

SODIUM

Method details

getId

public String getId()

The stable, portable identifier for this nutrient.

getUnit

public HealthUnit getUnit()

The unit amounts of this nutrient are expressed in.

forId

public static Nutrient forId(String id)

Looks a nutrient up by getId(), or null when unknown to this version of the framework.

values

public static List<Nutrient> values()

Every nutrient this framework understands.

toString

public String toString()

Returns a string representation of the object. In general, the toString method returns a string that “textually represents” this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method. The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@’, and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of: getClass().getName() + ‘@’ + Integer.toHexString(hashCode())
