Add Nutrition Data

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.

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).
