You can add nutrition data to Google Fit by creating a data source and using
the com.google.nutrition data type. Each data point represents the value
of all nutrients consumed in a meal or snack. This example shows you how to add
nutrition data for someone who's eaten a banana.
Creating a data source
Android
Use DataSource.Builder to create a new data source. For example, nutritionSource.
val nutritionSource = DataSource.Builder()
.setDataType(DataType.TYPE_NUTRITION)
// ...
.build()
REST
Call the REST API to create a new data source. For example, NutritionSource.

Request body
{
"dataStreamName": "NutritionSource",
"type": "raw",
"application": {
"detailsUrl": "http://example.com",
"name": "My Example App",
"version": "1"
},
"dataType": {
"name": "com.google.nutrition",
}
}
Response
If your data source was created successfully, you'll get a 200 OK HTTP
response status code. The response body contains a JSON representation of
the data source, including a datasource.dataStreamId property. Use this ID
as the dataSourceId to add data.

Adding nutrition data
Android
This example shows you how to create a new data point, and add nutrition
data for a banana, using the nutritionSource data source.
val nutrients = mapOf(
Field.NUTRIENT_TOTAL_FAT to 0.4f,
Field.NUTRIENT_SODIUM to 1f,
Field.NUTRIENT_SATURATED_FAT to 0.1f,
Field.NUTRIENT_PROTEIN to 1.3f,
Field.NUTRIENT_TOTAL_CARBS to 27.0f,
Field.NUTRIENT_CHOLESTEROL to 0.0f,
Field.NUTRIENT_CALORIES to 105.0f,
Field.NUTRIENT_SUGAR to 14.0f,
Field.NUTRIENT_DIETARY_FIBER to 3.1f,
Field.NUTRIENT_POTASSIUM to 422f
)
val banana = DataPoint.builder(nutritionSource)
.setTimestamp(timestamp, TimeUnit.MILLISECONDS)
.setField(Field.FIELD_FOOD_ITEM, "banana")
.setField(Field.FIELD_MEAL_TYPE, Field.MEAL_TYPE_SNACK)
.setField(Field.FIELD_NUTRIENTS, nutrients)
.build()
REST
This example shows you how to add a set of nutrition data using the
NutritionSource data source. The values for the nutrition data type are
nutrients (a map), meal type (4 = 'snack'), and the actual food item
(a string).
