food.get.v2

Description

Returns detailed nutritional information for the specified food. Use this call to display nutrition values for a food to users.

The only storable values returned by this call are the food_id unique identifier and the one or more serving_id unique serving size identifier values.

Why are we introducing version 2?

On May 27, 2016 the USA Food and Drug Administration (FDA) published new rules on the new Nutrition Facts label for packaged foods to reflect new scientific information, including the link between diet and chronic diseases such as obesity and heart disease.

Manufacturers in the USA with $10 million or more in annual sales were required to switch to the new label by January 1, 2020; manufacturers with less than $10 million in annual food sales have until January 1, 2021 to comply.

More information can be found here: Changes to the Nutrition Facts Label

Response

The food element returned contains general information about the food item with detailed nutritional information for each available standard serving size.

The general information returned is:

  • food_id – the unique food identifier.
  • food_name – the name of the food, not including the brand name. E.G.: "Instant Oatmeal".
  • food_type – takes the value "Brand" or "Generic". Indicates whether the food is a brand or generic item – see food_type.
  • brand_name – the brand name, only when food_type is "Brand". E.G.: "Quaker".
  • food_url – URL of this food item on www.fatsecret.com.

Nutrient values for each food item are returned according to the standard serving sizes available. The elements returned for each standard serving size are:

  • serving_id – the unique serving identifier.
  • serving_description – the full description of the serving size. E.G.: "1 cup" or "100 g".
  • serving_url – URL of the serving size for this food item on www.fatsecret.com.
  • metric_serving_amount is a Decimal - the metric quantity combined with metric_serving_unit to derive the total standardized quantity of the serving (where available).
  • metric_serving_unit – the metric unit of measure for the serving size – either "g" or "ml" or "oz" – combined with metric_serving_amount to derive the total standardized quantity of the serving (where available).
  • number_of_units is a Decimal - the number of units in this standard serving size. For instance, if the serving description is "2 tablespoons" the number of units is "2", while if the serving size is "1 cup" the number of units is "1". Please note that this is only applicable for when food_type is "Generic" whereas for "Brand" the number of units will always be "1".
  • measurement_description – a description of the unit of measure used in the serving description. For instance, if the description is "1/2 cup" the measurement description is "cup", while if the serving size is "100 g" the measurement description is "g".
